[Modes for carrying out the invention] 【0122】 A detailed description of one or more embodiments of the disclosed apparatus and method is provided herein with reference to the figures, as illustrative and not limiting. 【0123】 Embodiments of the present disclosure provide a child seat 20 that can be configured in various modes to accommodate different intended uses and seat heights, suitable for different child sizes (e.g., infants, toddlers, adolescents), different table sizes (standard, adolescent, counter), and different support surfaces (e.g., floor, chair). Referring to Figures 1A-3C, an example of the child seat 20 is illustrated in a first mode 20A (also referred to as high chair mode). In Figures 4-6C, an example of the child seat 20 is illustrated in a second mode 20B (also referred to as booster mode). In Figures 7A-8C, an example of the child seat 20 is illustrated in a third mode 20C (also referred to as youth chair mode). In Figures 9A-11A, an example of the child seat 20 is illustrated in a fourth mode 20D (also referred to as counter height mode). 【0124】 Referring to the figures, an example of a child seat 20 is illustrated. As shown, the child seat 20 comprises a seat assembly 22 and at least one leg 24 for placing the child seat 20 on a support surface, such as the floor. The seat assembly 22 includes a seat member 26 having a seat portion 28 oriented generally horizontally and at least one side wall, such as first and second upright side walls 30, respectively, positioned on opposing sides of the seat portion. A seat back 32 may be connected to at least one of the horizontal seat portion 28 and the upright side walls 30. In the non-limiting embodiments illustrated (Figures 2A-2C), the seat back 32 is approximately equal to the vertical height of one or both of the first and second upright side walls 30. However, embodiments in which the vertical height of the seat back 32 extends vertically beyond the vertical height of one or both of the first and second upright side walls 30 are also contemplated herein. In one embodiment, as shown in Figure 97, the vertical height of the sheet back 32 may vary between the side walls 30. As illustrated, the sheet back 32 may be formed to have a convex curvature or peak such that the vertical height of the central portion of the sheet back 32 is greater than the vertical height of the portions of the sheet back 32 adjacent to the first and second upright side walls 30. In one embodiment, the sheet member 26, including the sheet portion 28, the sheet back 32, and the upright side walls 30, is formed as a single, integrated component molded from, for example, plastic or composite material. However, embodiments in which at least a portion of the sheet member 26 is formed as a separate component permanently or detachably connected to the rest of the sheet member 26 are also within the scope of the disclosure. 【0125】 The seat portion 28, upright side wall 30, and seat back 32 of the seat member 26 work together to define a generally hollow interior 34 in which a child's body can be accommodated. Furthermore, the front portion 36 of the seat member 26 is open to accommodate the child's legs when the child is seated in the hollow interior 34. In one embodiment, the seat member 26 is intended for use by infants or toddlers who can support themselves in an upright position, typically children 6 months of age or older. Therefore, the seat member 26 is suitable for accommodating a child seated in contact with the seat portion 28, with the child's back at least partially supported by the seat back 32. 【0126】 The seat back extension member 38 may be removably connectable to the seat member 26 to increase the vertical height of the seat back 32. When connected, the seat back 32 and the seat back extension member 38 together extend vertically beyond the upright side wall 30. In such embodiments, the contour of the seat back extension member 38 may be, but not necessarily, substantially complementary to or identical to the contour of the seat back 32. The seat back extension member 38 may be formed from the same material as the seat back 32, or alternatively, from a different material than the seat member 26. The seat back extension member 38 may be connected to the seat member 26 via any preferred connection mechanism, such as a quick-connect mechanism. 【0127】 Referring here to Figures 56-59B, an example of a connection mechanism for securing the seat back extension member 38 to the seat member 26 is shown. In the non-limiting embodiments illustrated, the seat back extension member 38 includes one or more extension member mounts 250, such as two extension member mounts operable to selectively connect the extension member 38 to a portion of the seat member 26. As illustrated, each extension member mount 250 is similar to a clip and is insertable into a corresponding opening 252 formed in a portion of the seat member 26. The opening 252 is illustrated as being formed in a ledge 253 formed in the seat back 32, but it should be understood that in other embodiments, the opening 525 may be located elsewhere around the seat member 26. Hooks or other engagement features 254 (see Figures 59A-59B) may be formed on the distal end 256 of the extension member mount 250. When the seat back extension member 38 is installed around the seat member 26, such as by inserting the extension member mount 250 into the corresponding opening 252, the engagement feature 254 is configured to abut against the bottom surface 258 of a portion of the seat member 26 located adjacent to the opening 252. The engagement between the bottom surface 258 and the engagement feature 254 restricts the vertical movement of the seat back extension member 38 away from the seat member 26. 【0128】 By forming the extension member mount 250 from an elastic material, at least a portion of the extension member mount 250, such as its distal end 256, may be configured to bend relative to the seat back extension member 38, thereby disengaging the engagement feature 254 from the seat member 26. Continuing to refer to Figures 59A and 59B, to remove the seat back extension member 38 from the seat member 26, the user applies force to the distal end 256 of the extension member mount 250 in an inward direction, as indicated by arrow F. It should be understood that the direction of the force varies based on the position of the engagement feature 254 around the extension member mount 250. As illustrated, the end 256 of the extension member mount 250 may be positioned adjacent to an exposed surface of the seat back 32 that is easily accessible to the user. This force F bends or rotates the distal end 256 of the extension member mount 250, thereby aligning the engagement feature 254 with the opening 252 without contacting the adjacent surface 258. While the engagement feature 254 is in this bent position, the extension member mount 250 can be removed from the opening 252, thereby separating the seat back extension member 38 from the seat member 26. The clip exemplified in the non-limiting embodiments as the extension member mount 250 used to connect the seat back extension member 38 to the seat member 26 is intended only as an example, and it should be understood that any suitable connector or coupling mechanism, such as a snap-fit ​​connection, is also within the scope of this disclosure. 【0129】 The seat assembly 22 further includes a seat base 40 that supports its seat member 26. One or more legs 24 of the child seat 20 may be detachably connected to the seat base 40 to support the child seat 20 on a support surface. In one embodiment, the seat base 40 includes at least one leg mount 42 for receiving at least one leg 24. The at least one leg mount 42 may be an opening formed in the bottom surface 44 of the seat base 40. However, in other embodiments, the at least one leg mount 42 may project outward from the bottom surface 44 of the seat base 40. In such embodiments, the at least one leg mount 42 may form a seat base leg on which the seat assembly 22 can be supported on a support surface without one or more legs 24. In one embodiment best shown in Figure 5, the at least one leg mount 42 includes a pad or other friction surface 46 located at its distal end to prevent the seat base 40 from slipping against the support surface. 【0130】 Referring here to Figure 1, the tray 50 may be attachable to a portion of the child seat 20. The tray 50 may have a generally flat upper support surface 52 configured to support items such as food in a location easily accessible to the occupant of the seat member 26. In one embodiment, the tray 50 may be connectable to an adjacent surface of the seat member 26, such as the front or upper end of the upright side wall 30. In one embodiment, the tray 50 is a front tray that can be positioned directly in front of the torso of an occupant seated in the interior 34 of the seat member 26, in an arrangement that overlaps with the hollow interior 34 of the seat member 26. A tray horn 54, or in some embodiments, an arm bar (not shown), may be connected to the child seat 20, such as a seat assembly 22. In one embodiment, the tray horn 54 is permanently connected to the seat assembly 22. As used herein, “permanently connected” is intended to represent embodiments in which the tray horn 54 is not intended to be disassembled from the tray 50 by the user. Such connections may be formed by rivets, molding, or other preferred connecting mechanisms. In such embodiments, the tray 50 and tray horn 54 may be connected to the child seat 20 by the user when the child seat will be used by a younger infant, and may be detached from the child seat when it is intended for use by an older toddler or child. This connection between the tray 50 and a portion of the seat member 26, such as the seat member 26, may be formed by fasteners, snap-fit ​​connections, or other preferred connecting mechanisms, as will be described in more detail below. However, embodiments in which the tray horn 54 is detachable from the tray 50 are also contemplated herein. 【0131】 As illustrated, the tray horn 54 is intended to form a barrier that extends over at least a portion of the seat member 26 and, in some embodiments, over the entire front portion 36 of the seat member 26, thereby restricting the movement of a child over the front portion 36 of the seat member 26. The tray horn 54 may work in cooperation with the front portion 36 of the seat member 26 to define a first leg opening 52a and a separate or substantially separate second leg opening 52b located on either side of the tray horn 54. 【0132】 In one embodiment, the tray 50 can be positioned to overlap the upper surface 31 of the seat assembly 22, such that the tray 50 extends between the upright side walls 30 of the seat member 26. For example, a groove or channel (not shown) having a shape complementary to the contour of a portion of the seat assembly 22 may be formed on the lower surface 56 of the tray 50. It should be understood that the child seat 20 as exemplified and described herein is intended merely as an example, and any child seat having any preferred configuration is within the scope of this disclosure. 【0133】 Referring here to Figures 60-68, the illustrated tray 50 can be attached to a portion of the child seat 20, for example, the top or the seat member 26. As shown, the tray 50 may be connectable to the side wall 30 of the seat member 26. In a non-limiting embodiment, the tray 50 is part of a tray assembly that includes one or more connector elements 302a, 302b that are operable to engage with a portion of the seat member 26 in order to removably couple the tray 50 to the seat member 26. At least the connector elements 302a, 302b may be located near or adjacent to the rear edge 306 of the tray 50. For example, the first connector element 302a may be positioned around the tray 50 such that it is positioned substantially adjacent to the first side wall 30 of the sheet member 26, and the second connector element 302b may be positioned around the tray 50 such that it is positioned substantially adjacent to the second opposite side wall 30 of the sheet member 26. 【0134】 In one embodiment, the first connector element 302a and the second connector element 302b are engageable with a ledge 308 extending outward from the upper surface 31 of the side wall 30. At least one groove or slot 310, and in some embodiments, a plurality of slots 310, may be formed within the ledge 308, for example, on the lower surface of the ledge 308. Each portion of the connector elements 302a and 302b may be positioned in contact with the lower surface of the ledge 308, for example, by one or more slots 310, in order to restrict the movement of the tray 50 relative to the sheet member 26. 【0135】 In one embodiment, the tray 50 can be connected to the seat member 26 at multiple positions. In one embodiment, each of the multiple slots 310 defines a corresponding position among the multiple positions. The distance between the seat back 32 of the seat member 26 and the end of the tray 50 can vary among the multiple positions, allowing for adjustment based on the size of the child sitting in the seat member 26. 【0136】 The connector elements 302a and 302b may be movable between a first engaged position and a second disengaged position to selectively couple the tray 50 to and from the sheet member 26. In one embodiment, a bias mechanism 314 is operably coupled to the connector elements 302a and 302b. The bias force of the bias mechanism 314 is configured to bias each of the connector elements 302a and 302b toward the first engaged position. When a user applies force to either of the connector elements 302a or 302b, this force counteracts the bias force of the bias mechanism 314, which converts, for example, the connector elements 302a and 302b from the engaged position to the disengaged position. 【0137】 As illustrated, each of the connector elements 302a and 302b includes a latch body 316 movably mounted on the tray 50. For example, the latch body 316 may include one or more projections 318 slidably mounted in corresponding slots 319 (Figure 63) formed in the tray 50. The slots 319 may define a path of movement of the latch body 316, such as translation between an engaged position and an unengaged position. In the non-limiting embodiments illustrated, the path of movement of the latch body 316 is generally oriented in a horizontal plane. A bias mechanism 314 may be positioned between the tray 50 and the latch body 316 such that the bias force of the bias mechanism 314 applies a force to the latch body 316 toward the engaged position. 【0138】 In the non-limiting embodiments shown in Figures 60-65D, each connector element 302a, 302b includes a catch 320 movably coupled to a latch body 316. The catch 320 includes an engaging member 322 positioned to engage with a slot 310 formed in the sheet member 26 in order to couple the tray 50 to the sheet member 26. As shown, the catch 320 is movable relative to the latch body 316 between a first catch engagement position (Figures 62-65B, 65D) and a second catch disengagement position (Figure 65C). In one embodiment, a bias mechanism 324 is operably coupled to the catch 320 such that the bias force of the bias mechanism 324 biases the engaging member 322 of the catch 320 toward the catch engagement position. 【0139】 As the latch body 316 moves between the engaged and disengaged positions, the engagement between the ledge 308 of the seat member 26 and the surface of the engaging member 322 of the catch 320 is operable to counteract the bias force of the bias mechanism 324. In the illustrated non-limiting embodiments, the engaging member 322 has a first inclined surface 326 and a second inclined surface 328. During the installation of the tray 50 onto the child seat 20, the latch body 316 may be pulled to the disengaged position by the operator against the bias of the bias mechanism 314. Once the tray 50 is in the predetermined position relative to the seat member 26, the connector elements 302a, 302b are released, and the bias mechanism 314 pushes the latch body 316, including the catch 320, toward the seat member 26. 【0140】 As the latch body 316 and catch 320 move, the surface of the sheet member 26, such as the ledge 308, engages with the first inclined surface 326 and applies force. Because the first inclined surface 326 is sloped, this force pushes the engaging member 322 to a retracted position in a direction opposite to the bias force of the bias mechanism 324. In the retracted position, the engaging member 322 can move beyond the ledge 308 of the sheet member 26. As the ledge 308 moves so as not to contact the engaging member 322, the bias force of the bias mechanism 324 pushes the engaging member 322 back to the extended position. In the extended position, the engaging member 322 is received in a corresponding slot 310 formed in the ledge 308, thereby connecting the tray 50 to the sheet member 26. 【0141】 To separate the tray 50 from the sheet member 26, the user applies force to the connector elements 302a and 302b against the bias of the bias mechanism 314, thereby moving the connector elements 302a and 302b to the disengaged position. As the connector elements 302a and 302b, and thus the latch body 316 and catch 320, move relative to the tray 50 and the sheet member 26, the second inclined surface 328 of the engaging member 322 engages with the ledge 308 of the sheet member 26. As a result of the inclined configuration of the second surface 328, this engagement pushes the engaging member 322 into a retracted position against its bias, thereby allowing the engaging member 322 to move below the ledge 308 and away from the sheet member 26. 【0142】 Another embodiment of the connector elements 302a, 302b is illustrated in Figure 66. As shown, the catch 320 is pivotably mounted to a portion of a latch body 316 that is receivable below the ledge 308 of the seat member 26. Similar to the previous embodiment, the catch 320 may include an engaging member 322 located at its distal end, which includes at least one inclined surface. In such an embodiment, a biasing mechanism 324, such as a torsion spring, may be operable to bias the engaging member 322 to an extended position that is able to engage with the slot 310. In the non-limiting embodiment illustrated, the engaging member 322 includes a first inclined surface 326 and a second inclined surface 328. 【0143】 As described above, the connector elements 302a and 302b can be biased toward the engagement position by the bias mechanism 314. For example, while the connector elements 302a and 302b move toward the sheet member 26 as driven by the bias mechanism 314, the first surface 326 of the engagement member 322 contacts the ledge 308. This engagement rotates the engagement member 322 about its axis toward the retracted position in the first direction against the bias force of the bias mechanism 324. In the retracted position, the engagement member 322 can move beyond the ledge 308 to align with the corresponding slot 310. Once the force applied to the engagement member 322 by the ledge 308 is removed, the bias force of the bias mechanism 324 rotates the engagement member 322 toward the extended position and engages with the slot 310. Similarly, when the user moves the connector elements 302a and 302b away from the sheet member 26, or against the bias force of the bias mechanism 314, the second opposite surface of the engaging member 322 comes into contact with the ledge 308. The engagement between the ledge 308 and the second surface 328 rotates the engaging member 322 around its axis against the bias force of the bias mechanism to a second opposite retracted position. This rotation to the retracted position allows the engaging member 322 to pass under the ledge 308, thereby separating the connector elements 302a and 302b from the sheet member 26. 【0144】 In the embodiments disclosed in Figures 61-66, the engaging member 322 is a passive member that is driven to the disengaged position by engaging with the ledge 308 of the sheet member 26. However, in other embodiments, the engaging member may be actively moved to the disengaged position by the latch body. In non-limiting embodiments illustrated in Figures 67A-68, other embodiments of the connector elements 302a, 302b associated with the tray 50 are illustrated. As illustrated, the connector elements 302a, 302b may include a latch body 330 that is movable, for example, translatable, relative to the tray 50. In the non-limiting embodiments illustrated, the latch body 330 is movable vertically perpendicular to the flat support surface of the tray 50. A bias member (not shown) may be operable to bias the latch body 316 downward to the extended or engaged position. However, in other embodiments, gravity may be sufficient to bias the latch body 330 downward to the engaged position. 【0145】 The connector elements 302a and 302b further include a catch 340 pivotably mounted on the tray 50 and operably coupled to the latch body 330. The distal end of the catch 340 includes an engaging member 342 that can engage with a corresponding portion of the sheet member 26, for example, so as to be receivable in a corresponding slot 310, thereby coupling the tray 50 to the sheet member 26. While a hook-shaped or curved engaging member 342 is shown, it should be understood that engaging members 342 having other preferred configurations are within the scope of this disclosure. As shown, the engaging member 342 may be fixedly mounted on the catch 340 and, in some embodiments, may be integrally formed with the catch 340. A bias mechanism (not shown) may be operably coupled to the catch 340 and may be operable to bias the engaging member 342 of the catch 340 toward the engagement position. 【0146】 In the non-limiting embodiments illustrated in Figures 67A-67B, the latch body 330 includes an outwardly extending latch projection 332, and the catch 340 includes an outwardly extending catch projection 344 that can engage with the latch projection 332, thereby converting the catch 340 from an engaged position to an unengaged position. In other embodiments, such as those shown in Figure 68, the catch 340 may include an elongated flange 346 positioned in the path of movement of the latch body 330 between the engaged and unengaged positions. As shown, the elongated flange 346 is positioned either perpendicularly on the latch body 330 or overlapping the latch body 330. In either embodiment, movement of the latch body 330 to the unengaged position drives a corresponding movement of the catch 340 to the unengaged position. 【0147】 Regardless of the configuration of the interface between the latch body 330 and the catch 340, in order to connect the tray 50 to the sheet member 26, the user applies force to connector elements 302a, 302b, such as the latch body 330, thereby moving the latch body 330 upward to the engaged position. When the latch body 330 moves upward, it engages with the corresponding portion of the catch 340, such as the catch projection 344 or the elongated flange 346, and applies force. The force transmitted to the catch 340 rotates the catch 340 around its axis to the disengaged position. The engagement between the latch body 330 and the catch 340 can counteract bias forces acting on the catch. When the catch 340 is in the disengaged position, the engaging member 342 is positioned out of alignment with the ledge 308 of the sheet member 26. When the tray 50 is positioned around the sheet member 26, the latch body 330 is released. When the latch body 330 returns to the engaged position, the force acting on the catch 340 is released, and the engaging member 342 of the catch 340 is biased to engage with the sheet member 26. The tray 50 can be disengaged from the sheet member 26 by applying force to the latch body 330 again, separating the tray 50 from the sheet member 26 while the latch body 330, and therefore the catch 340, are in the disengaged position. 【0148】 In embodiments such as those illustrated in Figures 99A to 109C, the tray assembly 600 may include a tray 602 that can be attached to a portion of the child seat 20, so that the tray 602 can be positioned independently of the reclining of the seat member 26. For example, the tray 602 may remain substantially horizontal when the seat member 26 is reclined. In each of the illustrated non-limiting embodiments, the tray 602 has a generally planar upper support surface 604 configured to support one or more items, such as food. When attached to the child seat 20, the tray 602 may be positioned in a location easily accessible to the person seated in the seat member 26. In each of the illustrated non-limiting embodiments of the tray 602 that can be positioned independently of the reclining of the seat member 26, the tray 602 is attached adjacent to the outer surface of the seat assembly 22 in a position that does not obstruct access to or exit from the interior 34 of the seat member 26. Therefore, such a tray 602 may be considered a “side” tray rather than a front tray, such as tray 50, which can be positioned between the side walls 30 of the seat member 26. However, it should be understood that the aforementioned front tray is adjustable relative to the seat member 26 and can be adapted to control the position of such a tray independently of the reclining of the seat member 26. 【0149】 Each embodiment of the tray assembly 600 illustrated and described herein includes a mounting assembly 606 that can be permanently or removablely attached to a portion of the child seat 20. The mounting assembly 606 may be connectable to a surface of the seat member 26, such as the side wall 30, legs 24a-d, tray horn 54, arm bar, a combination thereof, or one or more front or top surfaces of other parts of the child seat 20. In some embodiments, the tray assembly 600 is connectable to the child seat 20 with or without the presence of the tray horn 54 or arm bar. 【0150】 In the non-limiting embodiments shown in Figures 99A to 99101, the mounting assembly 606 can be positioned in a configuration that overlaps with the upper surface 31 of one of the side walls 30 of the seat member 26. In embodiments in which the seat member 26 includes an armbar or tray horn 54, the mounting assembly 606 may be mounted in a configuration that overlaps with at least a portion of the armbar or tray horn 54 positioned on the side wall 30. As shown, the mounting assembly 606 may include a generally U-shaped or C-shaped channel member 608 having a hollow interior 610 complementary to the contour of the upper surface 31 of the side wall 30. The mounting assembly 606 can be assembled to the child seat 20 by pressing the channel member 608 downward onto the armrest or the upper surface 31 of the upright side wall 30. In some embodiments, the mounting assembly 606 is positioned around the upper surface 31 of the side wall 30 and slid forward, thereby locking the mounting assembly 606 into place around the child seat 20. 【0151】 In the exemplary, non-limiting embodiments, the tray 602 is rotatably coupled to the mounting assembly, such as the surface of a channel member 608 positioned adjacent to the outer surface of the upright side wall 30. Such a configuration allows the tray 602 to pivot about an axis relative to the mounting assembly 606 and the child seat 20. The tray 602 may be pivotable about an axis that extends generally horizontally, for example, laterally across the child seat 20, so that the tray 602 is movable in the same direction as the rotation of the seat member 26 during reclining. When the child seat 20 is reclined, the tray 602 can be rotated about its axis to a substantially horizontal position (see Figure 99B). 【0152】 Furthermore, the lock assembly 612 may be operably coupled to the tray 602 to lock the tray 602 in a desired position relative to the mounting assembly 606. The lock assembly 612 may include a button (or other actuator) 614, a bias mechanism 616 such as a compression spring, and a lock gear 618 configured to mesh with a complementary portion 619 of the mounting assembly 606. The bias mechanism 616 may bias the lock gear 618 to engage with the corresponding portion 619 of the mounting assembly 606. The bias force of the bias mechanism 616 may be counteracted by applying force to the actuator 614 to disengage the lock gear 618 from the corresponding portion 619 of the mounting assembly 606. In this operating state, the tray 602 can pivot to a desired position about its axis. When the actuator 614 is released, the lock gear 618 is biased in the reverse direction to engage with the corresponding portion 619 of the mounting assembly 606, thereby locking the tray 602 against rotation about its axis. 【0153】 The locking assembly 612 allows the tray 602 to rotate and lock in various positions relative to the mounting assembly 606. In one embodiment, the locking assembly 612 provides several distinct locking positions, each corresponding to a reclining position of the seat member 26. For example, the tray 602 may be configured to rotate a total of 25° around an axis, and each of the four distinct locking positions is adjusted by an 8.3° increment, corresponding to the 8.3° adjustment angle of each of the four (4) reclining positions of the seat member 26. However, it should be understood that the total rotation of the tray 602 and the distances between the distinct locking positions described herein are intended to be examples only, and various other angles and distinct positions are contemplated herein. 【0154】 Referring to Figures 102A–104, another embodiment of a tray assembly 600 that can be attached to the seat member 26 of a child seat 20 is illustrated. In the non-limiting embodiments illustrated, a mounting assembly 606 associated with a tray 602 may be operable to form a separate mechanical interlock between the tray 602 and the side wall 30 of the child seat. As shown in Figure 104, the mounting assembly 606 includes a plurality of engagement features 620a, 620b positioned on the surface 622 of the tray 602 configured to abut or face the surface of the seat member 26. The engagement features 620a, 620b are sized to receive within complementary receiving features 626 formed on the seat member 26, although other interfiting features are intended. In one embodiment, as shown in Figure 104, the engagement features 620a, 620b are provided in a plurality of different angular orientations. In this way, even if one or more receiving features 626 move with the seat member 26 during reclining, the tray 602 can be positioned at various angles relative to the seat member 26, including a substantially horizontal configuration, by attaching the tray 602 with appropriate engagement features. 【0155】 In the non-limiting embodiments described herein, the engagement features include a first pair of engagement features 620a having a first angular orientation and a second pair of engagement features 620b having a second angular orientation. For example, the first pair of engagement features 620a may be oriented for use when the seat member 26 is upright, and the second pair of engagement features 620b may be oriented for use when the seat member 26 is reclined. It will be understood that each angular orientation may include a single engagement feature or, alternatively, two or more engagement features. Furthermore, engagement features arranged in any preferred number of different angular orientations are contemplated herein. For example, in embodiments in which the seat member 26 can be positioned in a certain number of distinct reclining positions, at least one engagement feature may be provided for the corresponding number of angular orientations. A mounting assembly 606 having such a configuration would include engagement features having a specific angular orientation associated with each respective reclining position of the seat member 26. 【0156】 As shown in the figure, the engaging features 620a, 620b may be ribs having a J-shape, and the receiving feature may be a recess. The ribs 620a, 620b may be inserted into the recess 626 and abut against the bottom surface of the recess 626 to support the tray 602 in a cantilever configuration. In one embodiment, the recess 626 is the same recess located outside the side wall 30 and engageable by connector members such as connector elements 302a, 302b of a tray located at the front of the seat member 26, for example. Thus, in some embodiments, both the front tray and the side tray can be interchangeably mounted on the child seat 20 using the same receiving feature 626. 【0157】 While the tray 602 in Figures 102A-104 is shown having engagement features 620a, 620b in multiple different angular orientations, in other embodiments, such as those shown in Figures 105A-106B, the tray 602 may have one or more engagement features 620 in only a single angular orientation. In the exemplary, non-limiting embodiments, the engagement features 620 are oriented for use when the seat member 26 is upright. In such embodiments, the tray 602 is not adjustable to be positionable independently of the reclining of the seat member 26. However, in embodiments in which the seat member 26 includes multiple receiving features 626, such as recesses, the tray 602 may be selectively and adjustable to be positioned forward and backward relative to the child seat 20. 【0158】 Referring here to Figures 107A-108, an example of a tray assembly 600 that can be mounted on the seat base 40 of the seat assembly 22 is illustrated. Since the seat member 26 is movable relative to the seat base 40 between various reclining positions, the tray 602 maintains a constant position regardless of the reclining position of the seat member 26. In the non-limiting embodiments illustrated, the mounting assembly 606 for the tray 602 includes a support member 630 that can be connected to the seat base 40. The support member 630 is illustrated to extend from the underside of the tray 602, but it should be understood that a support member 630 mounted elsewhere around the tray 602 is also within the scope of this disclosure. As illustrated, the distal end 632 of the support member 630 may be received in a cavity 634 formed in the seat base 40. As illustrated, the opening 636 or other features formed in the support member 630 may engage with corresponding bosses or complementary features (not shown) in the cavity 634 to rigidly connect the tray 602 to the seat base 40. The connection between the support member 630 and the seat base 40 is intended merely as an example, and any preferred interface operable to connect the support member 630 and the seat base 40 is contemplated herein. 【0159】 In yet another embodiment, the tray 602 may be attached to one or more legs 24a-24d of the child seat 20 via a mounting assembly 606. In some embodiments, such as those shown in Figures 109A-109C, the mounting assembly 606 includes a clamp or releaseable clip 640, for example, an elastic C-shaped clip. The mounting assembly 606 may further include an arm 642 extending between the clip 640 and the tray. The length of the arm 642 may be selected to position the tray 602 at a usable height. In one embodiment, the arm 642 has a fixed length, but in other embodiments, the length of the arm 642 may be adjustable. In the illustrated non-limiting embodiments, the clip 640 is illustrated to engage with the legs 24a-24d such that the tray 602 is positioned at or near the corners of the seat member 26. However, in other embodiments, the mounting assembly 606 may be oriented to position the tray 602 in a different location, for example, adjacent to the outer surface of the upright side wall 30 of the seat member 26. It should be understood that the tray assembly 600 described in each of the embodiments in Figures 99A to 109C may be mounted on either the left or right side of the child seat 20. Furthermore, the first tray assembly 600 may be mounted in a first location around the child seat 20, and the second tray assembly may be mounted in a second location around the child seat 20. 【0160】 Continuing to refer to Figure 1, the seat assembly 22 is supported by at least one leg 24, and in some embodiments, by multiple legs 24 spaced apart from one another. In the non-limiting embodiments illustrated, the legs 24 are positioned generally adjacent to each corner of the seat assembly 22. Thus, as illustrated, the child seat 20 may include a first front right leg 24a, a second front left leg 24b, a third rear right leg 24c, and a fourth rear left leg 24d. Embodiments including different numbers of legs, such as a single leg, two legs, or three legs, should be understood to be within the scope of this disclosure. Each of the multiple legs 24 may be substantially identical. However, in other embodiments, the configuration of the legs 24 may vary. For example, the rear legs 24c, 24d may have a first configuration, and the front legs 24a, 24b may have a second configuration different from the first configuration. Although the overall cross-sectional shape and size of the front and rear legs 24a, 24b, 24c, and 24d appear to be identical, in some embodiments the axial length of the rear legs 24c and 24d may be greater than the axial length of the front legs 24a and 24b. 【0161】 The first ends 60 of each of the front legs 24a, 24b and rear legs 24c, 24d are configured to contact a support surface, such as the floor, to support the child seat 20 in an upright configuration. As shown in the figure, the second opposite ends 62 of each of the legs 24a, 24b, 24c, 24d are positioned adjacent to the corresponding portion of the seat assembly 22. At least one of the legs 24a-24d, and in some embodiments, each of the legs 24a-24d may have a generally linear configuration between a first end that can be positioned on a support surface and a second end 62 that can be connected to the seat assembly 22. However, in other embodiments, one or more of the legs 24a-24d may have a non-linear configuration. 【0162】 In one embodiment, as shown in Figure 11, the seat foot 61 is locatable on one or more first ends 60 of the legs 24a-24d. The seat foot 61 may include a pad 63 and a connector 65 that is operable to connect the pad 63 to the respective legs 24a-24d. As shown, when the seat foot 61 is connected to the leg, the seat foot 61 does not extend beyond the outer surface of the leg. In one embodiment, the seat foot 61 is collinear with the leg. 【0163】 As described above, one or more of the legs 24a to d may be detachably connectable to the seat assembly 22 to convert the child seat between different modes or operations. As illustrated, the second end 62 of at least one leg 24a to d may be connectable to the seat base 40, for example, at least one leg mount 42. In the non-limiting embodiments illustrated, at least one leg mount 42 protrudes beyond the bottom surface 44 of the seat base 40 in the form of a seat base leg, and the second end 62 of the legs 24a to d can be positioned in an arrangement that overlaps with the seat base leg along the axis. The second end 62 of the legs 24a to d may be receptible inside the hollow seat base leg, or alternatively, a portion of the legs 24a to d may be hollow so that the seat base leg is receptible inside the leg. 【0164】 The child seat described herein may be convertible between a first high chair mode and a second booster mode. In the first mode, the legs 24a-d are attached to the seat base 40 such that the child seat 20 can operate as a standalone high chair and the seat member 26 is positioned at approximately table height from the support surface. As used herein, the term “table height” is intended to describe embodiments in which a portion of the seat assembly, such as the upper end of the side wall 30 forming the armrest, is positioned between approximately 27.5 inches and approximately 30 inches from the support surface. The child seat 20 is positioned in the second mode when the legs 24a-24d are detached from the child seat. In the second mode, the child seat 20 may be configured as a booster seat. For example, a portion of the seat base 40, such as a seat base leg formed by at least one leg mount 42, may be positioned in contact with the top surface of another seat, such as an adult seat, to position the seat assembly 22 at approximately table height. 【0165】 Alternatively, or in addition, one or more of the legs 24a-d of the child seat 20 may be formed from a leg assembly having multiple components or parts that may be selectively included or omitted to provide the various modes disclosed herein. As described, in embodiments where the legs 24a-24d are assemblies formed from multiple parts, the child seat 20 may be able to transform into additional modes that cannot be achieved otherwise when the legs 24a-24d are formed from a single body. In one embodiment, each of the legs 24a-d is a leg assembly including an upper leg section 70 and a lower leg section 72. Furthermore, in some embodiments, such as those shown in Figure 8A, the leg 24 may additionally include an intermediate leg section or leg extension section 74 that can be positioned between the upper leg section 70 and the lower leg section 72. Interfaces between adjacent leg sections, such as between the upper leg section 70 and the lower leg section 72, may include, but are not required, washers or leg connectors 76 that separate adjacent leg sections. It should be understood that embodiments in which some of the legs 24a-d are leg assemblies comprising multiple parts, and other(may be) legs 24a-d are integral legs, are also within the scope of this disclosure. Furthermore, it should be understood that in embodiments in which multiple legs 24a-d are formed from leg assemblies, the components of each leg 24 may not be the same. For example, the front legs 24a-b may comprise an upper leg section 70 and a lower leg section 72, while the rear legs 24c-d may use relatively longer parts instead of the upper and / or lower leg sections. 【0166】 In embodiments where one or more of the legs 24 are formed via an assembly, it should be understood that one or more sections of the legs 24 can be connected to the seat assembly 22. For example, only the upper leg section 70 can be connected to the seat assembly 22, only the lower leg section 72 can be connected to the seat assembly 22, only the upper leg section 70 and the intermediate leg section 74 can be combined and connected to the seat assembly 22, only the lower leg section 72 and the intermediate leg section 74 can be combined and connected to the seat assembly 22, both the upper leg section 70 and the lower leg section 72 can be combined and connected to the seat assembly 22, or the upper leg section 70, the lower leg section 72, and the intermediate leg section 74 can be combined and connected to the seat assembly 22. 【0167】 The child seat 20 is convertible between multiple modes based on one or more sections of the legs 24a-d connected to the seat assembly 22. For example, the child seat 20 may be convertible between a first high chair mode (Figures 1A-2C), a second booster mode (Figures 3A-5), and a third youth chair mode (Figures 6A-7C). In the first mode, both the upper leg section 70 and the lower leg section 72 may be attached to the seat assembly 22 to position the seat assembly at table height. In the second booster mode, the legs 24a-24d may be removed entirely. In the third or youth chair mode, only a portion of the legs is connected to the seat assembly 22. For example, the lower leg section 72 may be attached to the seat assembly 22, while the upper leg section 70 and / or leg extension section 74 are detached from it. Alternatively, only the upper leg section 70 may be attached to the seat assembly 22, while the lower leg section 72 and / or leg extension section 74 are detached from the seat assembly 22. In some embodiments, the leg extension section 74 is connected to the seat assembly 22 in combination with either the upper leg section 70 or the lower leg section during operation in the third mode. When configured as a youth chair, the seat member 26 is positioned between approximately 10 inches and 25 inches from the support surface, for example, at the end of a side wall. 【0168】 The upper leg section 70 and the lower leg section 72 can have different vertical heights, and as a result, by coupling the upper leg section 70 and the lower leg section 72 to the seat assembly 22 respectively, two different modes can be achieved. For example, the seat assembly 22 with only the upper leg section 70 coupled may be suitable as an infant chair, while the seat assembly 22 with only the lower leg section 72 coupled may be suitable as a use chair for children older than infants. In one embodiment, the seat assembly 22 with only the upper leg section 70 coupled can position the seat portion 28 of the seat member 26 between about 10 and about 16 inches from the support surface, and the seat assembly 22 with the lower leg section 70 coupled can position the seat portion 28 of the seat member 26 between about 16 and about 25 inches from the support surface. 【0169】 When the child seat 20 is in the third use mode, a portion of the child seat 20 can be used to form a complementary play table separate from the child seat 20, such as the complementary play table 700 shown in FIGS. 110 - 112. In the exemplary embodiments of FIGS. 110 - 112, a first leg section, such as the upper leg sections 70a - 70d of each leg 24, is connected to the seat assembly 22. The seat back extension member 38 can be coupled to the seat assembly 22, but is not necessarily required. The play table 700 can include, for example, a tray 50 and one or more second leg sections of the leg assembly 24 coupled thereto to support the tray 50 on the support surface. In the illustrated non - limiting embodiment, the second leg section is the lower leg sections 72a - 72d. 【0170】 As illustrated, one or more fasteners 702 or connecting mechanisms may be coupled to or integrated with the tray 50, for example, on the underside 704 of the tray 50. The fasteners 702 may be complementary to at least a portion of the connecting mechanism 80 associated with each leg section 72a-72d of the leg assemblies 24a-24d. In some embodiments, the fasteners 702 may be identical to those embedded in the seat base 40 of the seat assembly 22 and may be configured to receive the legs 24a-24d and to couple to the seat base 40 (see Figure 114). For example, the fasteners 702 may have an upper connector 710 in the form of a threaded hole configured to receive the lower connector of the connecting mechanism 80, for example, a threaded bolt or screw. Thus, a portion of the legs 24a-24d, for example, the lower leg section, may be screwably connected to the fasteners 702 of the tray 50. 【0171】 In one embodiment, the tray 50 includes at least one, and in some embodiments, a plurality of sockets 712. A fastener 702 can be received in each of the plurality of sockets 712, for example, at the base of the socket 712 relative to the surface of the tray 50. In some embodiments, when the legs 24 are connected to the fastener, a portion of the legs 24 is also received in the socket 712. One or more bolts, screws, or other connecting devices (not shown) can be used to mount the fastener 702 in each of the sockets 712. In one embodiment, the body of the fastener 702 has at least one alignment slot 714 formed therein. A projection 716 extending inward from the side wall 718 of the socket 712 may be receivable in the corresponding alignment slot 714 to properly position or align the fastener 702 within the tray 50. 【0172】 In some embodiments, the child seat 20 may be additionally convertible to a fourth counter-height mode. In one embodiment, the legs 24, when in counter-height mode, include an upper leg section 70, a lower leg section, and a leg extension section 74, such that a portion of the seat assembly 22 is positioned at approximately counter-height. As used herein, the term “counter-height” is intended to describe embodiments in which a portion of the seat assembly 22, such as the upper end of the side wall 30 forming the armrest, is at least about 30 inches from the support surface. In some embodiments, in counter-height mode, the upper end of the side wall 30 forming the armrest is at least about 31 inches from the support surface, about 32 inches from the support surface, about 33 inches from the support surface, about 34 inches from the support surface, about 35 inches from the support surface, and in some embodiments, about 36 inches from the support surface. For example, the upper end of the side wall may be located between approximately 30 inches and approximately 36 inches from the support surface, and in some embodiments, between approximately 31 inches and approximately 36 inches, between approximately 32 inches and approximately 36 inches, between approximately 33 inches and approximately 36 inches, between approximately 34 inches and approximately 36 inches, between approximately 35 inches and approximately 36 inches, between approximately 31 inches and approximately 35 inches, between approximately 32 inches and approximately 35 inches, between approximately 33 inches and approximately 35 inches, between approximately 34 inches and approximately 35 inches, between approximately 31 inches and approximately 34 inches, between approximately 32 inches and approximately 34 inches, between approximately 33 inches and approximately 34 inches, between approximately 31 inches and approximately 33 inches, between approximately 32 inches and approximately 33 inches, and between approximately 31 inches and approximately 32 inches. 【0173】 As illustrated in Figure 9, it should be understood that when the child seat 20 is in counter height mode, the armrest of the seat assembly 22, as formed by the upper end of the side wall 30, is at a greater distance (higher) from the support surface than when the child seat is in the first mode, at table height. It should be understood that the seat assembly 22 and legs 24 of the child seat 20 may be packaged and sold as a kit that can be configured by the user. The various leg sections of the legs can be easily disassembled and reassembled by the user to convert the child seat to any one of the different modes. 【0174】 As shown in Figure 1, each of the multiple legs 24a-24d may extend from the seat base 40 at substantially the same angle. However, in other embodiments, such as those shown in Figure 55, the angle at which one or more legs extend from the seat base 40 (relative to the vertical plane) may differ from the angle at which another leg extends from the seat base 40. For example, the angle of one or more of the rear legs may be greater than the angle of one or more of the front legs. However, embodiments in which the angle of one or more of the front legs is greater than the angle of one or more of the rear legs are also within the scope of this disclosure. In one embodiment, the front legs 24a-24b extend forward from the seat base 40 at an angle of about 15 to about 25 degrees relative to the vertical plane, more specifically about 18 to about 22 degrees, for example, about 20 degrees. Similarly, the rear legs 24c-24d may extend backward from the seat base 40 at an angle of about 20 to about 30 degrees relative to the vertical plane, more specifically about 22 to about 27 degrees, for example, about 25 degrees. In embodiments where the forward angles of the front legs 24a, 24b differ from the rear angles of the rear legs 24c, 24d, the lateral angles of the front legs 24a, 24b and the rear legs 24c, 24d with respect to the vertical plane may be equal or vary. 【0175】 As described above, the first ends 60 of each leg 24a-24d are configured to contact the support surface. Referring to Figures 2A, 6A, and 8A, the footprint area of ​​the child seat 20 is an area having a geometric shape or linear distance defined by the interface points between the distal first ends 60 of the multiple legs 24 and the support surface. In some embodiments, such as when the legs 24a-24d have a generally linear configuration, the footprint area is the maximum area defined between the multiple legs 24a-24d. In the illustrated non-limiting embodiments of the child seat 20 including four legs, the footprint area has a geometric shape that is generally rectangular and, in some embodiments, square. However, it should be understood that footprint areas having other geometric shapes are also within the scope of this disclosure. For example, in other embodiments, such as when the child seat 20 includes, for example, three legs 24, the footprint area may be triangular. Similarly, in embodiments where the child seat 20 has only two legs, the footprint area may be defined by the straight-line distance between two points at the interface between the first end 60 of each leg 24 and the support surface. It should be understood that the lengths of each of the multiple legs 24 defined between their first end 60 and second end 62 may be the same or, alternatively, different. In embodiments with different lengths, the seat base 40 may be oriented at an angle nonparallel to the support surface. 【0176】 Because at least one of the legs 24a-24d is attached to the seat assembly 22 at a non-vertical angle, the footprint area changes as the lengths of the multiple legs 24a-24d change, such as by adding or removing leg segments from them. In embodiments where one or more of the legs 24a-24d extend outward from the seat assembly 22 at a non-vertical angle, the footprint area increases as the lengths of the legs 24a-24d increase. The lengths of the legs 24a-24d increase from a mode in which the child seat 20 is configured as a high chair, such that the legs 24 include only the upper leg section 70 and the lower leg section 72 (Figure 2A), and another mode in which the child seat 20 is configured as a counter-height seat, such that the legs 24 include the upper leg section 70, the lower leg section 72, and the leg extension section 74 (Figure 8A). Thus, the footprint area when the child seat 20 is configured as a counter-height seat is larger than the footprint area of ​​the child seat 20 when it is configured as a high chair. Similarly, a child seat 20 configured as a youth seat is shown in Figure 6A. As shown, the legs 24a-24d include only the upper leg section 70. Therefore, the footprint area of ​​the child seat 20 when configured as a high chair seat is larger than the footprint area of ​​the child seat 20 when configured as a youth chair. 【0177】 In embodiments in which the leg 24 comprises multiple components or sections, the leg further includes connecting mechanisms 80 between the components, for example, between the upper leg section 70 and the lower leg section 72, between the upper leg section 70 and the leg mount 42, between the upper leg section 70 and the leg extension section 74, or between the leg extension section 74 and the lower leg section 72. In one embodiment, two or more connecting mechanisms 80 may be duplicated or substantially identical, allowing for interchangeability along with ease of manufacture and assembly. 【0178】 Referring to Figure 10, an example of a connecting mechanism 80 is shown, such as one located between the leg extension section 74 and the lower leg section 72. As illustrated, the connecting mechanism 80 may include a lower connector 82 on the leg extension section 74 and an upper connector (not shown) on the lower leg section 72. The lower connector 82 may be a threaded part fixed to the leg extension section 74, and the upper connector may be a threaded receptacle in the lower leg section 72. In some embodiments, the lower connector is a metal threaded receptacle embedded in the material of the lower leg section 72. In other embodiments, the illustrated threaded connection may be replaced with various other removable mechanical connections (e.g., quick-connect parts, spring pins, threads on the leg itself, etc.). 【0179】 Each leg 24 or a section thereof can be connected to a part of the seat assembly 22, such as a fastener 83 (see Figure 114), a leg mount 42, etc., via a leg attachment 84. The leg attachment 84 may have any preferred configuration. An example of a leg attachment 84 is illustrated with reference to Figures 12A-17B. It should be understood that the leg attachment 84 may be substantially identical to the connecting mechanism 80 or may have a different configuration from the connecting mechanism 80. As illustrated, the leg attachment 84 includes a post 86 and a head 88 positioned at the first end 90 of the post 86, the head projecting radially outward beyond the post 86. The post 86 may be formed integrally with the head 88, permanently attached to the head, such as by welding to the head, or detachably coupled to the head, such as via multiple threads (Figures 14A-14C). It should be understood that the post 86 is not rotatable relative to the head 88 during use of the leg attachment 84. 【0180】 The head 88 may include various features to improve retention, assembly, etc., with either the seat base 40 or a portion of the leg 24. The post 86 may be screwed into a complementary connector formed on one or more portions of the leg 24, or into an opening formed in a fastener 83. In one embodiment, the post 86 is a metal part injection-molded together with the seat base 40. However, embodiments in which the leg attachment 84 is injection-molded together with a section of the leg 24 are also contemplated herein. As shown in Figures 18-20B, in one embodiment, the post 86 may be located in the central portion of the leg mount 42, such as within an opening 43 in the leg mount 42. The leg 24, or a section thereof, may have an upper connector 92 (see Figure 20B), such as a threaded part, complementary to the post 86, to enable engagement between the post and the connector. While the leg attachment 84 is illustrated and described herein as extending from the seat base 40, embodiments in which the leg attachment 84 is fixed to a leg or a section thereof such that a post 86 is receivable within the seat base 40 are also contemplated herein. 【0181】 Referring here to Figure 21, in another embodiment, the leg attachment 84 is a quick-connect coupling mechanism that does not require the use of any additional or external tools, such as a screwdriver. In the non-limiting embodiments illustrated, an engaging member 94 may be movably mounted on the seat base 40 or its leg mount 42. The engaging member 94 is shown to be generally circular, but it should be understood that any preferred shape is contemplated herein. The engaging member 94 may be movable between an extended position and a retracted position. In the extended position, the engaging member 94 protrudes beyond the outer surface of the leg mount 42 as shown, and in the retracted position, the engaging member 94 is generally receptive within the leg mount 42. A bias mechanism (not shown), such as a coil or torsion spring, may be operably coupled to the engaging member 94 and configured to exert a bias force on the engaging member 94 to maintain the engaging member 94 in the extended position. 【0182】 A through-hole or opening 96 (see Figure 32A) may be formed in a portion of the leg 24, such as a section of the leg 24 configured to overlap with or engage with the leg mount 42. The through-hole 96 is configured to receive at least a portion of the engaging member 94 in order to connect or lock the leg 24 in place with respect to the leg mount 42. In one embodiment, the size and shape of the through-hole 96 may be complementary to, and in some embodiments substantially identical to, the size and shape of the engaging member 94. 【0183】 To disengage the leg 24 from the leg mount 42, such as when switching the child seat from one mode to another, the user applies a force to the engaging member 94, represented by arrow F1. The force F1 applied by the user counteracts the bias force of the bias member, thereby moving or translating the engaging member 94 inward toward the retracted position. When the engaging member 94 is in the retracted position, the leg 24 can be translated linearly relative to the leg mount 42, such as away from the seat base 40. After the through-hole 96 of the leg 24 disengages from alignment with the engaging member 94, the force F1 is removed from the engaging member 94. As a result, the bias force of the bias member biases the engaging member 94 from the retracted position to the extended position. 【0184】 Similarly, to connect the leg 24 or a portion thereof to the seat assembly 22, a force F1 is applied to the engaging member 94 to retract the engaging member to the retracted position. While retracting, the leg 24 slides relative to the leg mount 42. It should be understood that the presence of the leg 24 is sufficient to hold the engaging member 94 in the retracted position once the force applied by the user is removed. Once the through-hole 96 of the leg 24 is aligned with the engaging member 94, the bias force of the bias member automatically shifts to return the engaging member 94 to the extended position so that the engaging member 94 is positioned within the through-hole 96 and, in some embodiments, protrudes beyond the through-hole 96. 【0185】 While the engaging member 94 is illustrated and described herein as being located on the leg mount 42, it should be understood that embodiments in which the engaging member 94 is located elsewhere, such as on the bottom surface 44 of the seat base 40, are also within the scope of this disclosure. Furthermore, it should be understood that the leg attachment 84 illustrated and described herein is intended only as an example, and any suitable leg attachment mechanism that allows the leg 24 or a section of the leg 24 of the child seat 20 to be easily coupled and uncoupled with the seat assembly 22 or another section of the leg 24 without the use of external tools is also within the scope of this disclosure. 【0186】 In the non-limiting embodiments illustrated in Figures 1A-2C and 8A-8D, examples of leg assemblies having various leg sections 70, 72, and 74 are shown. Another embodiment of leg assemblies 24a-24d is illustrated in Figures 69-74. The leg sections 70, 72, and 74 in the embodiments illustrated in Figures 1A-2C and 8A-8D may be formed solid or at least partially solid from, for example, wood material. However, in the non-limiting embodiments illustrated in Figures 69-74, one or more sections of the leg assembly may be formed as a hollow body. In the illustrated non-limiting embodiments, leg assemblies 24a-24d may similarly include an upper leg section 70, a lower leg section 72, and, in some embodiments, an intermediate leg section 74. 【0187】 Referring to Figures 69-74, in one embodiment, each of the upper leg section 70, the lower leg section 72, and the intermediate leg section 74 may be formed with at least one substantially open upper end 400, 402, 404 and substantially open lower ends 406, 408, 410. However, in some embodiments, the seat foot 412 is connectable to the lower end of one or more of the leg sections 70, 72, 74. However, embodiments in which the seat foot 412 is integrally formed with one or more of the leg sections, such as the lower leg section 72, are also contemplated herein. 【0188】 The connecting mechanism 420 can be positioned between adjacent portions of the leg assemblies 24a-24d to join the respective leg portions together. In one embodiment, two or more substantially identical connecting mechanisms can be used in the leg assemblies, enabling interchangeability of leg sections within the assembly, as well as ease of manufacture and assembly. The connecting mechanism 420 shown in FIGS. 69-74 includes one or more joining posts operable to form a quick-connect interface with one or more of the leg sections 70, 72, 74. In one embodiment, the joining post 420 is operable to form a snap-fit connection with at least one of the leg sections 70, 72, 74. 【0189】 Unlike the connecting mechanism 80 disclosed earlier herein with reference to FIG. 10, the joining post 420 as shown in FIGS. 69A-71B need not be integrally formed with a particular leg section. Rather, the joining post 420 can be removably coupled to any leg section 70, 72, 74 of the leg assemblies 24a-24d based on the operating mode of the child seat 20. For example, in an embodiment including both an upper leg section 70 and a lower leg section 72 as shown in FIGS. 71A-71B, the joining post 420 can be operable to join the upper leg section 70 and the lower leg section 72 together. In an embodiment including each of an upper leg section 70, a lower leg section 72, and an intermediate leg section 74, the leg assemblies 24a-24d can include a plurality of joining posts 420. As shown in FIGS. 72A-72B, the joining posts can include a first joining post 420a disposed between the upper leg section 70 and the intermediate leg section 74 and a second joining post 420b disposed between the intermediate leg section 74 and the lower leg section 72. In an embodiment where the leg assemblies 24a-24d include only a single leg section, such as the upper leg section 70 as shown in FIGS. 69A-69B, a single joining post 420 can be connected to its distal end to form the foot of the leg assemblies 24a-24d. 【0190】 In the exemplary, non-limiting embodiments, the joining posts 420, 420a, 420b include a first portion 422 and a second portion 424 separated by an annular projection or collar 426. The first portion 422 extends from a first end 428 of the joining post 420, 420a, 420b to the projection 426, and the second portion 424 extends between the projection 426 and a second opposite end 430 of the joining post 420, 420a, 420b. Furthermore, the diameters of both the first portion 422 and the second portion 424 may be equal to or slightly smaller than the inner diameter of the end of the corresponding sections 70, 72, 74 of the leg assembly 24. In one embodiment, the second ends 430 of the connecting posts 420, 420a, and 420b have a generally rounded or convex contour such that the second ends 430 form a foot that can be positioned in contact with the support surface of the child seat 20. 【0191】 The leg sections 70, 72, and 74 include one or more features configured to cooperate with joining posts 420, 420a, and 420b to connect the leg sections to the joining posts 420, 420a, and 420b. The lower leg section 72 and / or the intermediate leg section 74 may include contoured key features or recesses 440 formed on the sidewalls of the leg sections 72 and 74, such as near their upper ends 402 and 404. In a non-limiting embodiment, the joining posts 420, 420a, and 420b include outwardly extending bosses 442, such as those located on an annular projection 426. The bosses 442 are receivable within the corresponding key features 440. In one embodiment, similar key features 444 may be formed on the sidewalls of the upper leg section 70 and / or the intermediate leg section 74, such as near their lower ends 406 and 410. In embodiments where joining posts 420, 420a, and 420b are coupled to two leg sections, the boss 442 may be positioned within key features 440, 444 of both the upper and lower leg sections to rotatably align the respective leg sections 70, 72, and 74. 【0192】 One or more of the leg sections 70, 72, and 74 may optionally or additionally include a slot 446 formed in its side wall, such as near its upper end 400, 402, or 404. In embodiments in which the leg sections 70, 72, and 74 include both a key feature 440 and a slot 446, the slot 446 may be positioned vertically below the key feature 440 (see Figure 70). The joining posts 420, 420a, and 420b may include a latch 448 receivable within the slot 446 for coupling the lower leg section 72 or the intermediate leg section 74 to the joining posts 420, 420a, and 420b. The latch 448 may bend or retract relative to the joining posts 420, 420a, and 420b, thereby allowing the latch 448 to separate from the slot 446 of the adjacent leg sections 72 and 74. In one embodiment, the joining posts 420, 420a, 420b include buttons operably coupled to the latch 448 for selectively retracting or bending the latch 448. In some embodiments, the boss 442 may be configured as a button, but embodiments having another button accessible by the operator from outside the leg assemblies 24a-24d are also contemplated herein. 【0193】 A post or upper cap 450, separate from the joining posts 420, 420a, 420b, may be used to connect the respective leg sections 70, 72, 74 to the leg mount 42 of the seat assembly 22. As shown, the upper cap 450 may be receivable inside the leg sections 70, 72, 74, such as near its upper end 400, 402, 404. Similar to the joining posts 420, 420a, 420b, the upper cap 450 may have an elastic latch 452 that can engage with a portion of the leg sections 70, 72, 74. The latch 452 may be receivable in either a key feature 440 or a slot 446 formed within the lower and intermediate leg sections 72, 74. In one embodiment, the upper leg section 70 also has at least one slot 456 formed in its side wall near its upper end 400, from which the latch 452 can be receivable. A button 454 located on the upper cap 450 may be operable to retract a latch 452, thereby allowing the upper cap 450 to be separated from the leg sections 70, 72, and 74. In one embodiment, the button 454 is configured to extend through another opening 458 formed in the side wall of the upper leg section 70, or through either a key feature 440 or a slot 446 formed in the lower leg and intermediate leg sections 72, and 74. 【0194】 When the upper ends 400, 402, 404 of the leg sections 70, 72, 74, including the upper cap 450, are inserted into the leg mount 42 of the seat assembly 22, the latch 452 is configured to engage with a corresponding feature 460, such as a ledge formed on the inner surface of the leg mount 42 (see Figure 74). The leg sections 70, 72, 74 remain firmly fixed to the seat assembly 22 until the latch 452 retracts or moves away from its engagement with the ledge 460. Once separated, the leg sections 70, 72, 74 can be removed from the leg mount 42. As shown in Figure 74, the button 454 associated with the latch 452 on the upper cap 450 may be exposed even when the leg sections 70, 72, 74 are coupled to the seat assembly 22, for example, in a location directly below the end of the leg mount 42. In one embodiment, the upper cap 450 and the connecting posts 420, 420a, 420b may have substantially similar configurations such that the upper cap 450 and the connecting posts 420, 420a, 420b can be connected to any of the leg sections 70, 72, 74 of the leg assemblies 24a to 24d. 【0195】 In embodiments of leg assemblies 24a to 24d, which include connecting mechanisms 420, 420a, 420b separable from each of the multiple leg sections 70, 72, 74, one or more of the leg sections 70, 72, 74 and / or connecting mechanisms 420, 420a, 420b may be formed from a metallic material. However, in other embodiments, the leg sections 70, 72, 74 and / or connecting mechanisms 420, 420a, 420b may be formed from another suitable material, such as wood. It should be further understood that other embodiments of the leg assemblies described herein, such as a leg assembly having leg sections 70, 72, and 74 connectable via a connecting mechanism 80, may be formed from any suitable material, including wood or metal. 【0196】 Continuing to refer to Figure 21 and further to Figures 22A-22B, at least one attachment strap, webbing, or other tensioning member 100 may be associated with the seat base 40 to secure the child seat 20 to the seat. In one embodiment, the attachment strap 100 extends through an opening 102 formed in at least one leg mount 42. Although each of the multiple leg mounts 42 is illustrated to include an attachment strap 100, it should be understood that in some embodiments, the attachment strap 100 may be associated with only some of the leg mounts 42. In other embodiments, one or more attachment straps 100 may extend from a cavity or compartment formed in the seat assembly 22, such as the seat base 40, as will be described in more detail below. The attachment straps 100 may be used to removably connect the child seat 20 to a corresponding support surface when in a second booster mode. For example, one or more attachment straps 100 may wrap around the underside of the seat to connect the child seat 20 to the seat. In one embodiment, the attachment straps 100 are arranged in pairs, for example, with a first attachment strap associated with a first leg, such as the front left leg 24a, and a second attachment strap associated with a second leg, such as the front right leg 24c. In such an embodiment, one of the attachment straps 100 in the pair may have a buckle attached, and the other attachment strap 100 in the pair may have a clip that can be connected to the attached buckle, connecting the free ends of the attachment straps 100 to each other. 【0197】 The positioning of the mounting straps 100 relative to the seat base 40 prevents the legs 24 from being placed on the seat base 40 when the mounting straps 100 are extended from or suspended from the seat base 40, and thus prevents improper use of the child seat 20. In one embodiment, the child seat 20 includes a strap storage mechanism 110 for storing one or more mounting straps 100 when not in use (for example, in the first, third, or fourth mode). 【0198】 Referring to Figures 23A–23C, in one embodiment, the strap storage mechanism 110 may be directly integrated into the seat base 40. As shown, the strap storage mechanism 110 includes at least one seat storage compartment 112 formed in the seat base 40. A lid 114 is movably mounted on the seat base 40 and is operable to selectively seal the seat storage compartment 112, such as when one or more mounting straps 100 are placed therein. In one embodiment, the seat storage compartment 112 is inaccessible due to a locking mechanism 116 that is enabled or engaged when the legs 24 are connected to the seat base 40. In the non-limiting embodiments illustrated in Figures 23A–24B, the locking mechanism 116 includes a movable locking pin 118. When the locking pin 118 is in the unlocked position (Figure 23B), the locking pin 118 extends into the opening 43 of the leg mount 42 and does not engage in any way with any portion of the lid 114. In the locked position, the locking pin 118 does not extend into the opening 43 of the leg mount 42, but rather engages with a portion of the lid 114 to hold the lid closed relative to the seat storage compartment 112. A bias mechanism (not shown) may be operably coupled to the locking pin 118 such that the biasing force of the bias mechanism biases the locking pin 118 to the unlocked position. 【0199】 The lid 114 is convertible between an open position and a closed position when the locking pin 118 is in the unlocked position. The locking pin 118 may be movable, for example, translatable, from the unlocked position to the locked position in response to the connection of the leg 24 to the leg mount 42. For example, the leg 24 is receivable within the opening 43 of the leg mount 42 during installation so that the leg 24 applies a force F2 to the locking pin 118. The force F2 counteracts the bias force of the bias mechanism and converts the locking pin 118 from the unlocked position to the locked position. In one embodiment, the locking pin 118 is movable to the locked position only when the lid 114 is closed to the seat storage compartment 112. Furthermore, the lid 114 may only be closed when one or more mounting straps 100, which are receivable within the seat storage compartment 112, are fully housed within the compartment. If a portion of the mounting strap 100 extends outward from the seat storage compartment 112, the lid 114 engages with the mounting strap 100, thereby preventing the corresponding portion of the lid 114 from aligning with the locking pin 118. The locking mechanism 116 illustrated and described herein is intended only as an example, and it should be understood that other suitable locking mechanisms are within the scope of this disclosure. 【0200】 Another example of a locking mechanism 500 that can operate to selectively lock the lid 114 to the seat base 40 to seal the seat storage compartment 112 is illustrated in Figures 75–79B. In the non-limiting embodiments illustrated, the locking mechanism 500 includes a locking pin 502 that is movable between a locked position (Figures 76, 78A) and an unlocked position (Figure 78B). Similar to the previous embodiments, the locking pin 502 does not extend into the opening 43 of the leg mount 42 when in the locked position, and extends into the opening 43 of the leg mount 42 when in the unlocked position. The locking pin 502 is further mounted on a first pin or projection 506 that extends outward from the surface 508 of the lid 114. The first projection 506 is located in a corresponding slot 510 formed in the seat base 40. As shown in the figure, the lid 114 is pivotable about an axis as defined by a second projection 512 that extends from the lid 114 and into a corresponding groove (not shown) formed in the seat base 40. The translation of the first projection 506 in the slot 510 defines the rotation of the lid 114 about the axis of the second projection 512. The bias mechanism 514 is operably coupled to the lock pin 502 such that the bias force of the bias mechanism 514 biases the lock pin 502 toward the unlocked position. 【0201】 The actuation mechanism 520 is located on the seat base 40 and is operably coupled to the lid 114. In the exemplary, non-limiting embodiments, the actuation mechanism 520 includes, for example, an actuator 522, such as a button located on the surface of the seat base 40, and an engaging member 524 operably coupled to the actuator 522. A rib 526 may extend from a portion of the lid 114, and the engaging member 524 of the actuation mechanism 520 may cooperate with the rib 526 to counteract the bias force of the bias mechanism 514. For example, the engaging member 524 may abut against the rib 526 to prevent the lid 114 from rotating toward the open position. 【0202】 As described above, the lid 114 is switchable between a closed position and an open position when the locking pin 502 is in the unlocked position. The locking pin 502 is movable to the unlocked position in response to the operation of the actuator 522. Applying force to the actuator 522 separates the engaging member 524 from the rib 526. As a result, the bias force acting on the locking pin 502 biases the locking pin 502 toward the interior 43 of the leg mount 42, thereby translating the first projection 506 of the lid 114 within its slot 510. This translation rotates the lid 114 around the axis of the second projection 512. 【0203】 The actuator 522 cannot open the lid 114 when the leg 24 is in the leg mount 42. Applying force to the actuator 522 moves the engaging member 524 away from contact with the rib 526, but the presence of the leg 24 counteracts the bias force of the bias mechanism 514. Thus, the leg 24 prevents the lock pin 502 from moving, and therefore prevents the first projection 506 from translating toward the open position within its slot 510. 【0204】 In embodiments where at least a portion of the leg 24 has a hollow interior 25, the hollow interior may form a leg storage compartment for receiving the mounting strap 100. Referring here to Figure 25, the mounting strap 100 may be installed in the interior 25 of the leg 24 before connecting the leg 24 to the seat base 40. In embodiments where the leg mount 42 can be received within the interior 25 of the leg 24, the mounting strap 100 may be positioned vertically below the leg mount 42. 【0205】 In one embodiment, the child seat 20 includes a footrest 120 that can be attached to one or more legs 24 at a position vertically offset from the front portion 36 of the seat member 26. The position of the footrest 120 may be fixed or adjustable relative to the seat portion 28 of the seat member 26. In the non-limiting embodiment illustrated in the figures, the footrest 120 is single-positionable relative to one or more legs 24. However, it should be understood that embodiments in which the footrest 120 can be fixedly attached to the legs 24 at two or more positions are also contemplated herein. Furthermore, it should be understood that in some embodiments, the footrest 120 is detachable from the legs 24, and therefore the child seat 20 can be used without the footrest 120 attached to it. 【0206】 In each of the illustrated embodiments, the footrest 120 includes a footrest body 122, the footrest body 122 having a generally planar upper surface 124 on which a child can position one or more feet. In the non-limiting embodiments of Figures 26-30, the footrest 120 is supported by a cross brace assembly 130. The cross brace assembly 130 can be attached to the child seat 20 by being sandwiched between adjacent sections of the legs, for example, between the upper leg section 70 and the lower leg section 72. As illustrated, the cross brace assembly 130 may include a front brace 132, side braces 134, 136, and a rear brace 138. However, it should be understood that cross brace assemblies 130 having only one, two, or three of the identified cross braces are also contemplated herein. As shown in the figure, a disc-shaped washer or leg connector, such as a leg connector 76, may be placed in one or more of the interfaces formed between adjacent cross braces. The leg connector 76 may have an opening therein through which at least a portion of a leg 24, such as a connecting mechanism 80, may extend. 【0207】 The cross brace assembly 130 may be formed as a single, rigid component. For example, in some embodiments, such as those shown in Figures 26 and 27, the braces 132, 134, 136, 138 and leg connectors 76 may be formed from a metallic material, and the braces 132, 134, 136, 138 may be permanently fixed to their respective leg connectors 76 located at the corners of the cross brace assembly 130, for example, by welding or riveting. In other embodiments, such as those shown in Figures 80 and 81, the cross brace assembly may be formed from a mixture of materials. For example, the braces 132, 134, 136, 138 may be formed from a metallic material, such as a metal tube, while the leg connectors 76 may be formed from a different material, such as plastic. In such embodiments, the braces 132, 134, 136, 138 may be detachably connected to the leg connectors 76 via any preferred mechanism, including but not limited to pop rivets, barco snaps, and screws. 【0208】 In some embodiments, the child seat 20 may comprise a kit having multiple cross brace assemblies in different arrangements. For example, a cross brace assembly 130 including four braces 132, 134, 136, and 138 may be used when the child seat is in a fourth counter-height mode, and a cross brace assembly 130 having one, two, or three braces may be used when the child seat is in another mode. In some embodiments, the leg connector 76 may be omitted or separated from the cross brace assembly 130, in which case the cross brace assembly 130 may include a ring or other structure that mechanically engages with one or more of the legs 24a to d. 【0209】 As shown in the figure, the footrest 120 may be connected to at least one cross brace, such as the front cross brace 132. In one embodiment, the footrest 120 is integrally formed with the front cross brace 132. In other embodiments, the footrest 120 may be detachably coupled to the front cross brace 132. For example, the bottom of the footrest 126 may include a recess (not shown), and a corresponding portion of the front cross brace 132 may be received in the recess for connecting the footrest 120 to the cross brace assembly 130. Alternatively, or in addition, a locking mechanism may be used to lock the footrest 120 in place around the cross brace assembly 130 and prevent the footrest 120 from rotating relative to it. 【0210】 In other embodiments, the footrest 120 is mounted via engagement with one or more legs 24. Referring to Figures 1A and 31A-32B, in the exemplary non-limiting embodiments, the body 122 of the footrest 120 includes at least one opening 140 into which a leg 24 can be received. For example, a footrest engaging member 142, such as a guide rib, extends radially inward from the inner surface of the opening 140. A retaining element 144, such as a groove or recess, which is geometrically complementary to the footrest engaging member 142, may be formed on the surface of a leg 24 adjacent to the footrest engaging member 142. The leg 24 may further include one or more holes 146, also referred to herein as retaining stops, formed along the retaining element 144, for example, at its end. When the footrest engaging member 142 is aligned with the retaining element 144 (Figure 32A), the body 122 of the footrest 120 is translationally responsive to the leg 24. When the engagement retainer 144 is aligned with or engaged with the retainer stop 146, a portion of the footrest engagement member 142 extends to or abuts against the retainer stop 146, thereby locking the footrest 120 in a predetermined position relative to the leg 24. 【0211】 To install the footrest 120, the legs 24 are aligned with each opening 140 formed within the footrest body 122, so that the footrest engaging member 142 of each opening 140 aligns with the corresponding engaging stopper 144. The user then manually moves the footrest 120 relative to the legs 24 by applying force to the footrest body 122 until the footrest engaging member 142 contacts the respective stopper 146. In one embodiment best shown in Figure 26, the front legs 24a, 24b of the child seat 20 are positioned at non-parallel angles to each other. As a result, the horizontal clearance defined between the front legs 24a, 24b changes from the support surface toward the seat member 26, for example, gradually decreasing. Thus, as the footrest body 122 is translated toward the desired position relative to the legs 24, the relative orientation of the legs 24 changes. For example, the angle α defined between the legs 24 when they are first connected to the footrest, also referred to herein as the insertion angle (see Figures 31A, 33A), is approximately zero. The legs 24 transition from being approximately parallel to being positioned at an angle to each other. The connection between the footrest 120 and the multiple legs 24 orients the multiple legs 24 at a desired angle. In one embodiment, when the footrest body 122 is in its final position, the legs 24 are positioned at a desired angle to each other, and their second ends 62 are appropriately positioned or aligned with the leg mounts 42 of the seat base 40 in order to connect the legs 24 to the seat base 40. 【0212】 Referring here to Figures 82-96C, alternatively, or in addition to the footrest 120, the child seat 20 may include a support member assembly 550 that can be positioned beneath the seat assembly 22, such as within a defined area between several legs 24a-24d. In one embodiment, the support member assembly 550 is a basket assembly having a support member, such as a fabric basket 551, and a frame for mounting the support member or basket 551 to the child seat 20. In some embodiments, such as those shown in Figures 82-85B, a cross brace assembly 130 functions as a frame that can operate to support the basket 551. As illustrated, the basket 551 has one or more sides 552a, 552b, 552c, 552d, formed, for example, from a fabric material and connected by a central fabric section 554, such as one formed from a mesh material. In one embodiment, one or more of the sides 552a, 552b, 552c, and 552d may include a tunnel or passage 556 configured to receive the corresponding cross braces 132, 134, 136, and 138 of the cross brace assembly 130 for connecting the basket 551 to the cross brace assembly 130. In one embodiment, components of the cross brace assembly 130 may be detachable to allow the basket 551 to be separated from the cross brace assembly 130. In such embodiments, the sides 552a to 552d of the basket 551 fabric may be sewn together so that the tunnel 556 is permanently formed therein. 【0213】 Alternatively, as shown in Figures 84A and 84B, the basket 551 may include one or more fastening mechanisms 558, such as zippers, snaps, or hook-and-loop fasteners, which can be converted by an operator to open and close their respective tunnels 556 in order to selectively connect the basket 551 to the corresponding braces of the cross brace assembly 130. In embodiments in which the tunnels 556 are formed via one or more fastening mechanisms 558, the cross brace assembly 130 may be a single body or may be disassembled as previously described. It should also be understood that the basket 551 as described herein may be mounted on a cross brace assembly 130 with a footrest 120 attached or integrally formed with it (see Figures 85A and 85B). 【0214】 Referring here to Figures 86-88B, in another embodiment, the basket 551 can be coupled to a cross brace assembly 130, which is at least partially formed from a plastic material. In such an embodiment, the leg connector 76 of the cross brace assembly 130, which is formed from, for example, a plastic material, may be insertable into a slot 462 formed in a portion of the leg of the child seat. As shown, the leg may be configured as leg assemblies 24a-24d, and the slot 462 may be formed within coupling posts 420, 420a, 420b that are operable to connect two adjacent leg sections of the leg assemblies 24a-24d, such as an upper leg section 70 and a lower leg section 72. When the coupling posts 420, 420a, 420b are coupled to the lower leg section 72, refer to Figures 88A and 88B, the distal ends of the coupling posts 420, 420a, 420b are received within the lower leg section 72. Furthermore, when fully coupled, the lower leg section 72 may be configured to overlap a portion of the leg connector 76, thereby preventing the leg connector 76 from separating from the leg assemblies 24a-24d. Only after the lower leg section 72 has separated from the joining posts 420, 420a, 420b can the leg connector 76 be removed from the slots 462 formed in the joining posts 420, 420a, 420b. Although the joining posts 420, 420a, 420b are illustrated and described as receivable within the lower leg section 72, it should be understood that in some embodiments, the joining posts 420, 420a, 420b may alternatively be receivable within the intermediate leg section 74. 【0215】 In other embodiments of the support member assembly 550 shown in Figures 89A-95, the frame operable to support the basket 551 is a footrest brace 572 having a single body including a plurality of sides 574a, 574b, 574c, 574d arranged in a general ring shape. Although the footrest brace 572 is illustrated to have four sides, it should be understood that embodiments including fewer than four sides, such as three or even two sides, are also within the scope of this disclosure. One of the plurality of sides 574a, 574b, 574c, 574d of the footrest brace 572 may extend further outward than the other sides of the footrest brace 572 to form a functional footrest similar to the footrest 120. The basket 551 may be positioned centrally between the sides 574a, 574b, 574c, and 574d of the footrest brace 574, and may be coupled to one or more of its sides 574a, 574b, 574c, and 574d. 【0216】 The upper end 578 of the basket 551 (see Figures 91 and 92) can be permanently fixed to the footrest brace 572, for example, on the underside of the footrest brace 572, or alternatively, it can be detachably coupled. In one embodiment, the upper end 578 of the basket 551 includes a plastic rod 580. The plastic rod 580 may, but does not have to be, formed integrally with the basket 551. As shown, the upper end 578 of the basket 551 may have an opening or tunnel 582 formed therein that extends around at least a portion of the periphery of the basket 551, and the plastic rod 580 may be positioned within the tunnel. The plastic rod 580 may be held in place relative to the footrest brace 572 by one or more retaining features 584, for example, an undercut ledge. 【0217】 As illustrated, the notches 586, such as U-shaped notches, may be formed in one or more locations, for example, at one or more corners of the footrest brace 572. In the non-limiting embodiments illustrated, retaining locks 588 are positioned within each notch 586 and are operable to engage with the legs of the child seat 20 positioned within the notches 586. Furthermore, the retaining locks 588 may cooperate with an undercut ledge 584 to hold the upper end 578 of the basket 551 in place relative to the footrest brace 572. In Figure 93B, the retaining locks 588 are shown engaging with features of the joining posts 420, 420a, and 420b of the leg assemblies 24a to 24d, such as a boss 442. This engagement restricts the movement of the basket 551 relative to the footrest brace 572, and thus to the leg assemblies 24a-24d, unless the operator intentionally bends the retaining lock 588 by disengaging from the features 442 of the joining posts 420, 420a, and 420b. 【0218】 In other embodiments, the footrest brace 572 may be adapted for use with a leg assembly such as leg assemblies 24-24d having a plurality of leg sections 70, 72, 74 that can be connected via a screw connection mechanism 80. Referring to Figures 94-96C, circular mounting brackets or leg connectors 590 may be positioned at each corner of the footrest brace 572 within the aforementioned notches 586. As shown, each mounting bracket 590 has a hole 592 for receiving the connection mechanism 80 through which it passes. The mounting brackets 590 may be formed integrally with the footrest brace 572, as shown in Figures 94 and 95A-C. However, in other embodiments, the mounting brackets 590 may be detachably connected to the footrest brace 572. In the non-limiting embodiments illustrated in Figures 96A-96C, the mounting brackets 590 are exemplified as being detachably connected to the footrest brace 572 via fasteners (not shown), such as screws. It should be understood that other suitable connection mechanisms may also be used, including a mechanism that can be connected via a biased engagement similar to that of the aforementioned retaining lock 588. 【0219】 In embodiments where the mounting bracket 590 is detachable from the footrest brace 572, the mounting bracket 590 may function as an adapter based on each of the legs 24a-24d of the child seat 20. For example, the footrest brace 572 may be adapted for use with wooden legs, such as including one or more leg sections 70, 72, 74 of a leg assembly, by including the mounting bracket 590, or it may be adapted for use with one or more at least partially metal legs, such as leg assemblies 24a-24d, by removing one or more mounting brackets 590 from the footrest brace 572. In such embodiments, the mounting bracket 590 may be connectable in an arrangement that overlaps with the retaining lock 588. 【0220】 Referring here to Figures 33A to 52B, the first part of the seat assembly 22 may be movable relative to the second part of the seat assembly 22. In one embodiment, the seat member 26 is movable relative to the seat base 40 between a first seat member position and a second seat member position. For example, in one embodiment, the seat member 26 is translationally movable forward (towards the front legs) and backward (towards the rear legs). Alternatively, or in addition, the inclination angle of at least a portion of the seat member 26 may be adjustable so that the seat member 26 is movable relative to the seat base 40 between an inclined position (first inclined position or first seat member position) and a reclined position (second inclined position or second seat member position). It should also be understood that the seat member 26 may be positioned at one or more positions defined between the first seat member position and the second seat member position. 【0221】 During movement along an inclined path, the seat back 32 of the seat member 26 is configured to rotate about an axis offset from the intersection point between the seat back 32 and the seat portion 28. In the non-limiting embodiments shown in Figures 34A to 37B, the entire seat member 26 is movable relative to the seat base 40 to control the inclination or recline of the seat member 26. As illustrated, a reclining lock mechanism 150 may be mounted on the seat member 26. In the exemplary non-limiting embodiments, the reclining lock mechanism 150 includes a reclining cap 152 that can be positioned in an arrangement that overlaps with the bottom surface of the seat member 26. Thus, when the seat member 26 is mounted on the seat base 40, the reclining cap 152 is positioned between the seat member 26 and the seat base 40. The reclining lock mechanism 150 may additionally include, for example, at least one reclining pin 154 located in a cavity formed within the reclining cap 152. In the exemplary, non-limiting embodiments, the reclining lock mechanism 150 includes a plurality of reclining pins, such as a first reclining pin 154 and a second reclining pin 154, arranged on opposing sides of the reclining cap 152, and a bias mechanism 156, such as a coil spring, extending between the first reclining pin 154 and the second reclining pin 154 and operably coupled. 【0222】 The reclining pins 154 can be simultaneously switched between a first locked position (Figure 35A) in which the seat member 26 is not movable relative to the seat base 40, and a second unlocked position (Figure 35B) in which the seat member 26 is movable relative to the seat base 40, in order to adjust the inclination of the seat member 26. When each of the reclining pins 154 is in the locked position, the end 158 of the reclining pin 154 extends through an opening 160 formed in the reclining cap 152 and engages with a corresponding locking opening 162 formed in a portion of the seat base 40. When the reclining pin 154 is in the second unlocked position, the second end 158 of the reclining pin 154 is separated from or disengaged from the locking opening 162, allowing the seat member 26 to be tilted or reclined. 【0223】 The actuator 164 is operably coupled to the reclining lock mechanism 150. The actuator 164 may include a handle 166 positioned on the outer surface of the seat assembly 22, such as the surface of the seat back 32. In embodiments where the upper surface of the seat back 32 is curved, such as those shown in Figures 97-98B, the handle 166 may be positioned near the top of the arch or convex curvature. In one embodiment, the handle 166 has a plurality of angled slots 168 formed therein (see Figures 37A and 37B), and engaging pins 170 extending from each reclining pin 154 are positioned in the corresponding slots 168 formed in the handle 166. When a force F3 is applied to the handle 166, the handle 166 is configured to move relative to the seat member 26, such as relative to the seat back 32. As shown in Figures 98A and 98B, when operated, the upper end of the handle 166 may be receivable within the clearance defined between the ledge 253, which extends outward from the upper surface of the seat back 32, and the outer surface of the seat back 32. 【0224】 When a force F3 is applied to the handle 166, the engagement pin 170 is configured to translate within the slot 168, for example, from a first position adjacent to the first end of the slot 168 to a second position adjacent to the second opposite end of the slot 168. Due to the angled configuration of the slot 168, the recliner pin 154 is configured to translate inward relative to the opening 160 formed in the recliner cap 152 as the engagement pin 170 translates within the slot 168. The force applied to the engagement pin 170 via the movement of the handle 166 exceeds the bias force of the bias mechanism 156 operably coupled to the recliner pin 154. However, when the handle 166 is released, the bias force of the bias mechanism pushes the recliner pin 154 outward, moving the handle 166 relative to it and returning it to the deacting position. 【0225】 The seat member 26 is translationally movable relative to the seat base 40 while the reclining pin 154 is held in the unlocked position by applying a force F3 to the handle 166. As best shown in Figure 34B, the seat base 40 includes a plurality of locking openings 162, each associated with a different inclination of the seat member 26. Thus, the seat member 26 is movable to a position configured such that the end 158 of the reclining pin 154 aligns with and engages with each of the locking openings 162 of the plurality of locking openings. Once aligned, the handle 166 is released, locking the reclining pin 154 into engagement with each locking opening 162. The reclining locking mechanism 150 illustrated and described herein is intended only as an example, and it should be understood that any suitable mechanism for selectively locking and unlocking a portion of the seat assembly 22 to adjust the inclination of the seat member 26 is within the scope of this disclosure. 【0226】 Referring here to Figures 38A-38C, the final assembly steps of the seat member 26 to the seat base 40 are illustrated, allowing them to be separated for shipment. As shown, the upper surface 41 of the seat base 40 includes flexible or elastic fingers 172, and the outer surface of the reclining cap 152 has a slot 174 formed therein. Once the seat member 26 is aligned with the upper surface 41 of the seat base 40, the user slides the seat member 26 in the direction F5 shown in Figure 38C, elastically retracting the flexible fingers 172. The seat member 26 is then mounted to the seat base 40 when the elastic flexible fingers 172 move freely upward and engage with the slot 174 formed in the reclining cap 152 connected to the seat member 26. In this mounted configuration, the seat member 26 is virtually impossible to disassemble from the seat base 40. 【0227】 Referring here to Figures 43-48, another embodiment of a seat assembly 22 having a reclining lock mechanism 150 and a lock actuator 164 similar to those in the embodiments of Figures 33A-38C is illustrated. As shown in Figure 46, the reclining cap 152 of the reclining lock mechanism 150 may include curved slots 153 formed on one or more of its sides, and adjacent surfaces of the seat base 40 may include corresponding curved ribs 155 that can be received within the curved slots 153. It should be understood that embodiments in which the ribs 155 are formed in the reclining cap 152 and the slots 153 are formed in the seat base 40 are also within the scope of this disclosure. 【0228】 Alternatively, or in addition, at least one base reclining groove 157 may be formed on the upper surface 41 of the seat base 40, and at least one seat reclining member 159 extending from the bottom of the seat member 26 may be receivable within the corresponding base reclining groove 157. The engagement between the seat reclining member 159 and the corresponding end face 161 of the base reclining groove 157 may define an end position or stopping position (Figure 45) relative to the seat base 40 along the inclination path of the seat member 26. In one embodiment, the engagement between the seat reclining member 159 and the corresponding end face 161 of the base reclining groove 157 limits the separation of the seat member 26 from the seat base 40. 【0229】 Referring here to Figures 47A-48, the final assembly steps of the seat member 26 to the seat base 40 are shown, and they can be separated during shipment. As shown in Figure 47A, the reclining cap 152 is positioned in the reclining orientation (second inclined position) and lowered on the base. From this reclined position, the reclining cap 152 can be moved relative to the seat base 40 so that one or more ribs 155 of the seat base 40 are positioned in one or more slots 153 of the reclining cap 152 (Figure 47B). As shown in Figure 47C, once the slots 153 and ribs 155 are fully engaged and positioned in the upright position (first inclined position), the seat member 26 can be lowered onto the seat base 40 and engaged with the reclining lock mechanism 150. The reclining cap 152 can be fixed to the seat member 26 using, for example, multiple fasteners, with the seat reclining member 159 positioned within the base reclining groove 157 (see Figure 48). 【0230】 Referring here to Figures 39A to 42B, in one embodiment, the seat back 32, and in some embodiments, a seat back extension member 38 connectable to it, are movable relative to the seat member 26 and the rest of the seat base 40, adjusting the inclination of the seat member 26. In one embodiment, the seat back 32 and / or the seat back extension member 38 are movable relative to the seat member 26 between a first seat back position (upright or first inclined position) and a second seat back position (reclined or second inclined position). It should also be understood that the seat back 32 and / or the seat back extension member 38 may be positioned in one or more positions defined between the first seat back position and the second seat back position. 【0231】 In the exemplary, non-limiting embodiments, the curved rib 180 has at least one side facing outward and, in some embodiments, protrudes from the opposite side of the seat back 32. A corresponding curved slot 182 is formed in the seat member 26, such as a portion of the side wall 30. The engagement between at least one rib 180 and at least one slot 182 defines an inclined path for the seat back 32 relative to the rest of the seat member 26. In one embodiment, the front end of the curved slot 182 (see Figure 40) extends perpendicularly below the seat portion 28 of the seat member 26, such that when the seat back 32 is positioned in the reclining position, the end of the seat back 32 is positioned below the seat portion 28. Such a configuration results in a generally smooth surface extending from the seat portion 28 to the seat back 32 and / or seat back extension member 38, thereby improving user comfort when in the reclining configuration. Embodiments illustrated and described herein include a rib 180 attached to the seat back 32 and a slot 182 formed in the side wall 30 of the seat member 26, but it should be understood that embodiments in which the rib 180 protrudes from the seat member 26 and is receivable within the slot 182 formed in the seat back 32 are also within the scope of this disclosure. 【0232】 A reclining lock mechanism 190 may be used to selectively lock the seat back 32 at a desired inclination relative to the seat member 26. The reclining lock mechanism 190 may be similar to the reclining lock mechanism 150 described above with reference to Figures 34A-37B. As shown, the reclining lock mechanism 150 may include one or more reclining pins 192 that project radially outward from the surface of the seat back 32 and engage with at least one locking opening 194 formed in the seat member 26. The reclining pins 192 are illustrated and described herein as being located in the seat back 32, and the locking opening 194 is illustrated and described as being located in the side wall 30 of the seat member 26, but it should be understood that embodiments in which the reclining pins 192 are located in the seat member 26 and the locking opening 194 is formed in the seat back 32 are also within the scope of this disclosure. 【0233】 The actuator 200 includes a handle 202 operably coupled to a reclining pin 192. When a force F4 is applied to the handle 202, the reclining pin 192 is translated from a locked position engaged with a corresponding locking opening 194 to an unlocked position away from the locking opening 194. The direction of movement of the handle 202 in response to the force F4 may be set at an angle with respect to the direction of movement of the reclining pin 192 between the locked and unlocked positions. A bias mechanism (not shown) may bias the reclining pin 192 to the locked position when the handle 202 is released. Any preferred connection between the reclining pin 192 and the handle 202 is contemplated herein. For example, the reclining pin 192 may be operably coupled to a pivot member (not shown) rotatable about an axis in response to the operation of the handle 202 to translate the reclining pin 192. 【0234】 In some embodiments, where the seat back portion 32 and / or seat back extension member 38 are movable relative to the seat member 26 between a first seat back position and a second seat back position, the seat member 26 is fixedly mounted to the seat base 40 or integrally formed with the seat base 40. In such embodiments, as shown in Figures 39A-42B, the seat portion 28 and side walls 30 of the seat member 26 are not movable relative to the seat base 40. However, in other embodiments, the seat member 26 is movable relative to the seat base 40 between a first seat member position and a second seat member position. For example, the seat member 26 may be configured to translate relative to the seat base 40 and / or to be inclined relative to the seat base 40, as previously described with respect to Figures 33A-38C and 43-47C. In such embodiments, the seat member 26 may be considered movable relative to the seat base 40 along a first path between a first seat member position and a second seat member position, and the seat back 32 and / or seat back extension member 38 may be considered movable relative to the seat member 26 along a second path between a first seat back position and a second seat back position. It should be understood that the first path may have at least one of a linear configuration and an inclined configuration. 【0235】 In embodiments where the seat member 26 is movable relative to the seat base 40, and the seat back 32 and / or seat back extension member 38 are movable relative to the seat member 26, the movement of the seat member 26 relative to the seat base 40 may occur independently of the movement of the seat back 32. In such embodiments, a first actuator, such as actuator 164, is associated with the seat member 26 and is operable to move the seat member 26, and a second actuator, such as actuator 200, separate from the first actuator, is associated with the seat back 32 and / or seat back extension member 38 and is operable to move the seat back 32 and / or seat back extension member 38. 【0236】 However, it should be understood that embodiments in which the reclining lock mechanism 150 associated with the seat member 26 is operably coupled to, or integrated with, the reclining lock mechanism 190 associated with the seat back 32 and / or the seat back extension member 38 are also within the scope of this disclosure. In such embodiments, a single actuator may be operable to unlock both reclining mechanisms to allow adjustment of the position of either the seat member 26, the seat back 32 and / or the seat back extension member 38, or both. 【0237】 Furthermore, in one embodiment, movement of either the seat member 26 or the seat back 32 and / or the seat back extension member 38 can drive movement of the other seat member 26 or the seat back 32 and / or the seat back extension member 38. For example, movement of the seat back 32 and / or the seat back extension member 38 to a second seat back position can cause the seat member 26 to move away from the first seat member position relative to the seat base 40, for example, by reclining. Alternatively, or in addition, the seat back 32 and / or the seat back extension member 38 may move from the first seat back position in response to the seat member 26 reaching the second seat member position. Although it has been explained that the movement of the seat member 26 or the seat back 32 and / or the seat back extension member 38 occurs in response to the other of the seat member 26 or the seat back 32 and / or the seat back extension member 38 reaching its respective second position, it should be understood that the movement of the seat member 26 and / or the seat back 32 and / or the seat back extension member 38 can occur at any position along the first and second paths, respectively. 【0238】 When an existing high chair is in a fully upright and reclined position, its center of gravity typically lies vertically beneath the seat assembly, between the front and rear legs. When the seat back of an existing high chair is in the fully reclined position, the center of gravity shifts backward, and sometimes outward, beyond the rear legs. This backward shift of the center of gravity makes the high chair unstable when the seat is reclined. 【0239】 Referring here to the child seat 20 illustrated in Figures 52A and 52B, the center of gravity of the child seat 20 with a child seated on it may be located between the front and rear legs of the child seat 20 in both the tilted position and the fully reclined position. The term “fully reclined position” is intended to include embodiments in which the seat member 26 is in the second seat member position and the seat back 32 and / or seat back extension member 38 are in any position relative to the seat member 26, embodiments in which the seat back 32 and / or seat back extension member 38 are in the second seat back position and the seat member 26 is in any position relative to the seat base 40, and embodiments in which the seat back 32 and / or seat back extension member 38 are in the second seat back position and the seat member 26 is in the second seat member position. 【0240】 The center of gravity of the child seat 20 may be based at least in part on the weight of the child seated in the child seat 20. For example, continuing to refer to Figures 52A and 52B, a child seat 20 seated in a child approximately 0–3 months old has a first center of gravity associated with the seat assembly 22 in the tilted position (Figure 52A) and a second center of gravity associated with the seat assembly 22 in the fully reclined position (Figure 52B). The average weight associated with a 0–3 month old seated child may be 10–20 pounds, 12–20 pounds, 15–20 pounds, 18–19 pounds, and in some embodiments may be approximately 18 pounds or more, such as 18.167 pounds. Similarly, a child seat 20 seated in a child approximately 1 year old has a first center of gravity associated with the seat assembly 22 in the tilted position (Figure 53A) and a second center of gravity associated with the seat assembly 22 in the fully reclined position (Figure 53B). The average weight associated with a seated child of approximately 1 year of age may be 20–28 pounds, 22–28 pounds, 24–28 pounds, 25–26 pounds, and in some embodiments, it may be approximately 26 pounds or more than 25 pounds, for example, 25.636 pounds. Referring to Figures 54A and 54B, a child seat 20 seated with a child of approximately 3 years of age has a first center of gravity associated with the seat assembly 22 in the tilted position (Figure 54A) and a second center of gravity associated with the seat assembly 22 in the fully reclined position (Figure 54B). The average weight associated with a seated child of approximately 3 years of age may be 28–40 pounds, 28–38 pounds, 32–36 pounds, 33–34 pounds, and in some embodiments, it may be approximately 34 pounds or less than 34 pounds, for example, 33.825 pounds. It should be understood that the size and weight of the seated child will vary depending on the mode of the child seat. As mentioned above, the total length of one or more of the legs 24 may be determined by the mode of the child seat 20. 【0241】 In one embodiment, the second center of gravity of the child seat 20 is located closer to the front legs 24a-24b of the child seat 20 than the first center of gravity. Therefore, the center of gravity may shift toward the front legs as the seat assembly 22 changes from the tilted position and the reclined position. In other embodiments, as shown in Figures 52A-54B, the second center of gravity of the child seat 20 may be located closer to the rear legs of the child seat 20 than the first center of gravity. Therefore, in such embodiments, the center of gravity may shift toward the rear legs as the seat assembly 22 changes from the tilted position and the reclined position. 【0242】 Alternatively, the location of the center of gravity may remain substantially constant between the tilted position and the reclined position of the seat assembly 22. As used herein, the term “substantially constant” is intended to describe embodiments in which the center of gravity does not move, or moves only a small distance, such as 3 mm or less, when the seat assembly 22 transitions between the tilted position and the fully reclined position. 【0243】 When the seat assembly 22 is in both the fully upright and fully reclined positions, the center of gravity of the child seat 20 with a seated person may be located in front of the vertical axis X, which is midway between the front and rear legs. However, embodiments are also contemplated herein in which the center of gravity associated with the seat assembly 22 in the tilted position is located on the opposite side of the vertical axis X as the center of gravity associated with the fully reclined position, and embodiments in which the center of gravity of the child seat 20 with a seated person is located behind the vertical axis X when the seat assembly 22 is in both the fully upright and fully reclined positions. In embodiments in which the center of gravity moves in response to reclining the seat assembly 22, the center of gravity may remain located between the front and rear legs of the child seat 20 when the seat assembly 22 is in both the upright and fully reclined positions. 【0244】 As described above, the center of gravity of the child seat 20 may shift as the seat assembly transitions between the tilted and reclined positions. The center of gravity may be able to move by any suitable distance in either the forward or backward direction. However, in one embodiment, the horizontal distance between the center of gravity associated with the seat assembly 22 in the tilted position and the center of gravity associated with the seat assembly 22 in the reclined position may be less than 2 inches, and in some embodiments, it may be less than 1 inch or half an inch in any given direction such as upward, downward, forward, and backward. For example, referring to Figures 52A and 52B, the second center of gravity of the child seat 20 is located about 0.078 inches below and / or about 0.075 inches behind the first center of gravity. Similarly, referring to Figures 53A and 53B, the second center of gravity of the child seat 20 is located about 0.077 inches below and / or about 0.043 inches behind the first center of gravity. In the non-limiting embodiments of Figures 54A and 54B, the second center of gravity of the child seat 20 is located approximately 0.055 inches below and / or approximately 0.036 inches behind the first center of gravity. 【0245】 Referring here to Figures 49A-50, in one embodiment, the seat member 26 includes a recess or indentation 210 formed in the seat portion 28. The recess 210 may form a hole through which the crotch strap 212 of the harness assembly can be extended. In such an embodiment, an elastic tab or projection 214 may extend inward from the lower surface of the seat member 26, for example from a reclining cap 152, to engage with a corresponding anchor 216 of the crotch strap to secure the crotch strap 212 in place around the seat member 26. 【0246】 In other embodiments, as shown in Figure 51, the recess 210 may engage with the seat pad 220 to restrict the movement of the seat pad 220 relative to the seat member 26, regardless of whether the crotch strap 212 is fixed to the seat member 26. In one embodiment, the seat pad 220 includes a seat pad projection 222 that is receivable in an arrangement overlapping the upper surface of the seat portion 28 of the seat member 26 and is situable within the recess 210. The configuration of the seat pad projection 222 may, but does not have to be, substantially identical to the configuration of the recess 210. 【0247】 The term "approximately" is intended to include the degree of error associated with the measurement of a particular quantity, based on the equipment available at the time of filing. 【0248】 The technical terms used herein are for the sole purpose of describing specific embodiments and are not intended to limit this disclosure. Where used herein, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise. The terms “comprises” and / or “comprising,” where used herein, specify the presence of the described features, components, steps, actions, elements, and / or components, but do not exclude the presence or addition of one or more other features, components, steps, actions, elements, components, and / or groups thereof. 【0249】 This disclosure is described with reference to one or more exemplary embodiments, but it will be understood by those skilled in the art that various modifications may be made and equivalents may be substituted for their elements without departing from the scope of this disclosure. In addition, many modifications may be made to adapt the teachings of this disclosure to specific circumstances or materials without departing from the essential scope of this disclosure. Thus, this disclosure is not limited to any particular embodiment disclosed as the best mode intended for carrying out this disclosure, and this disclosure is intended to include all embodiments that fall within the claims.
