[0118] A detailed description of one or more embodiments of the disclosed apparatus and method is illustrated herein with reference to the figures, by way of example and not limitation.

[0119] Referring now to FIG. 1 , an example of a support base 20 configured to receive a child seat for use in a child restraint system is shown, according to an embodiment. The support base 20 can be removably secured to a vehicle seat 2 ( FIG. 17 ), such as via a latch or anchor mechanism (not shown). This commonly used latch or anchor system is sometimes referred to as a “lower anchor and tether for children” (e.g., a LATCH system). Alternatively, or in addition, the support base 20 can be removably secured to the vehicle seat 2 via a vehicle belt 12 (see FIG. 18 ) associated with the vehicle seat 2, as described in more detail below.

[0120] As shown, the support base 20 includes a base body 22 having a seat portion 24 and a back portion 26. Suitable materials for manufacturing the base body 22 include, but are not limited to, rigid plastics and composite materials. While the seat portion 24 and the back portion 26 are illustrated as being formed as a unitary structure, embodiments in which the seat portion 24 and the back portion 26 are separate components that are removably or permanently connected are also within the scope of the present disclosure. The seat portion 24 has a bottom surface 28 suitable for placement on a support surface, such as a vehicle seat (see FIG. 17 ). The back portion 26 is disposed at a first end 30 of the seat portion 24 and is extendable obliquely therewith. In the illustrated non-limiting embodiment, the back portion 26 forms an angle of between approximately 75 degrees and approximately 120 degrees with respect to the bottom surface 28 of the seat portion 24. However, it should be understood that embodiments in which the angle formed between the back portion 26 and the bottom surface of the seat portion 24 is less than 75 degrees or greater than 120 degrees are also contemplated herein.

[0121] In the illustrated non-limiting embodiment, a stabilization leg 32 having a fixed or adjustable length is coupled to a portion of the base body 22, such as, for example, a second, opposite end 34 of the seat portion 24. The stabilization leg 32 may be rotatable or foldable relative to the seat portion 24 between an extended configuration ( FIG. 1A ) in which the stabilization leg 32 abuts the vehicle floor and a retracted configuration ( FIG. 1B ) in which the stabilization leg 32 is stored below or within the seat portion 24 of the support base 20. When in the retracted configuration, the stabilization leg may protrude slightly from the bottom surface 28 of the seat portion 24 to facilitate use of the stabilization leg 32 when attaching the support base 20 to the vehicle seat 2.

[0122] 47A, in one embodiment, the rotation axis A of the stability leg 32 may lie in a plane defined by the bottom surface 28 of the seat portion 24. In other embodiments, the rotation axis A of the stability leg 32 may be vertically offset from the bottom surface of the seat portion 24. For example, as shown in FIG. 47B, the rotation axis may be located approximately centered between the top and bottom surfaces 28 of the seat portion 24. However, it should be understood that stability legs having a rotation axis location anywhere between the top and bottom surfaces 28 of the seat portion, and even vertically below the bottom surface 28 of the seat portion 24, are within the scope of the present disclosure.

[0123] With continued reference to FIG. 1A and further reference to FIGS. 2-4, 8, and 16, the support base 20 can include a belt tensioner 35 coupled to the base body 22. In the illustrated non-limiting embodiment, a groove 36 formed in the base body 22 extends from the seat portion 24 to the back portion 26, with the belt tensioner 35 receivable within the groove 36. However, it should be understood that embodiments in which the groove 36 is formed only in the back portion 26 of the base body 22 are also contemplated herein. The contour of the belt tensioner 35 can be complementary to the contour of the groove 36 such that substantially the entire belt tensioner 35 is received within the groove 36. The vehicle belt 12 associated with a vehicle seat in which the support base 20 is positionable can be positioned along a belt receiving path defined between the belt tensioner 35 and an outer or upper surface 38 of the base body 22, such as the back portion 26 of the base body 22. In one embodiment, the belt tensioner 35 is selectively movable relative to the base body 22 to adjust the tension applied to the vehicle belt 12 along the vehicle belt receiving path. For example, the belt tensioner 35 may be configured to pivot about at least one axis to selectively pinch a portion of the vehicle belt 12 sandwiched between the belt tensioner 35 and the groove 36 to couple the support base 20 to the vehicle belt 12, thereby limiting movement of the support base 20 relative to the vehicle seat.

[0124] 2-4, 8, and 16, the belt tensioner 35 is formed from a single member pivotally coupled to the support base 20 at a first end. However, in other embodiments, such as those shown in FIGS. 20A and 20B, the belt tensioner 35 may be an assembly including multiple tensioning members operably coupled to one another. In the illustrated non-limiting embodiment, the belt tensioner 35 includes a first tensioning member 130 movably coupled to the support base 20 at its first end 132 and a second tensioning member 134 movably coupled to the first tensioning member 130 at a second, opposite end 136, etc. Although the first tensioning member 130 is illustrated as rotatably coupled to the support base 20 and the second tensioning member 134 is illustrated as rotatably coupled to the first tensioning member 130, embodiments in which one or both of the first and second tensioning members 130, 134 are otherwise movable are also contemplated herein. Additionally, embodiments in which the second tensioning member 134 is movably coupled directly to the support base 20 rather than to the first tensioning member 130 are also within the scope of the present disclosure.

[0125] In the unlocked position, as shown in FIG. 20B , the first tensioning member 130 of the belt tensioner 35 is rotated away from the groove 36, and the second tensioning member 134 is disposed at a non-parallel angle relative to the first tensioning member 130. In such an embodiment, a respective biasing mechanism (not shown) may be associated with each rotational axis of the first and second tensioning members 130, 134. In the locked position, the first and second tensioning members 130, 134 are disposed generally parallel to one another. In the illustrated, non-limiting embodiment, the first tensioning member 130 has a recess 138 formed in its first surface 140, e.g., configured to face toward a seat portion receivable on the support base 20. The size of the recess 138 may be complementary to the second tensioning member 134 such that the second tensioning member 134 is nestably positionable within the recess 138 of the first tensioning member 130. In such an embodiment, the surface 142 of the second tensioning member 134 facing toward the sheet portion receivable on the support base may be generally flush with the first surface 140 of the first tensioning member 130. In other embodiments, the recess may be formed on the back surface of the second tensioning member 134 such that the first tensioning member 130 is nestably positionable within the second tensioning member 134.

[0126] As shown in FIG. 20A , when in the locked position, the second tensioning member 134 is disposed parallel to the first tensioning member 130. A distal end 144 of the second tensioning member 134 may be selectively couplable to the first tensioning member 130, such as via a locking mechanism. In the illustrated, non-limiting embodiment, the locking mechanism includes a spring-biased first feature 146 configured to complement and engage a corresponding second feature 148 disposed on the first biasing member 130. The first feature 146 may be a tooth or tab that is biased to a position where the tooth protrudes beyond the distal end 144 of the second biasing member 134. As shown, a portion of the first feature 146 may be accessible to a user when the belt tensioner 35 is in the locked position. Thus, a user can apply force to the accessible portion to retract the first feature 146 toward the tip 144 and separate it from the second feature 148, thereby disengaging the tip 144 of the second tensioning member 134 from the first tensioning member 130. It should be understood that in other embodiments, a feature of the locking mechanism formed on the first tensioning member 130 may alternatively or additionally be movable by a user to selectively unlock the belt tensioner 35.

[0127] In one embodiment, the second tensioning member 134 has a tab or engagement member 150 protruding therefrom. While the engagement member 150 is illustrated as being located near the end 136 of the second tensioning member 134, embodiments in which the engagement member 150 is located at another location on the second tensioning member 134 are also within the scope of this disclosure. When the belt tensioner 35 is in a locked configuration, such as when the belt tensioner 35 is disposed within the groove 36, the engagement member 150 is receivable within a corresponding opening 152 formed in the surface of the support base 20 that is adjacent to, and in some embodiments defines, the groove 36. In such an embodiment, during a locking operation, the first tensioning member 130 is swung toward the groove 36. Once properly positioned, rotating the second tensioning member 134 toward the first tensioning member 130 positions the engagement member 150 within the opening 152. Thus, the second tensioning member 134 is rotatable like a lever relative to both the first tensioning member 130 and the support base 20. The mechanical advantage of this lever-type configuration reduces the user-applied force required to deform the belt tensioner 35 to the locked position when the vehicle belt 12 is positioned between the groove 36 of the belt tensioner 35 and the first tensioning member 130.

[0128] In one embodiment, best shown in FIGS. 21A-21C, one or more belt guides 160 may be positioned about the support base 20, such as on the back 26. While substantially identical belt guides 160 are shown positioned on opposite sides of the back 26, it should be understood that embodiments having a single belt guide are also within the scope of this disclosure. Furthermore, in embodiments including multiple belt guides 160, the belt guides may have various configurations and / or may be positioned at different vertical and lateral locations based on the vehicle belt path relative to the support base 20. As shown, the belt guide 160 may include a slot 162 connected to an internal opening 164 that receives a portion of the vehicle belt 12 therein. At least one belt guide 160 is positioned to maintain the portion of the vehicle belt 12 not held in place by the belt tensioner 35 away from the area of ​​the support base 20 associated with the receivable seat. The at least one belt guide 160 can also, for example, align the vehicle belt 12 with the support base 20, prevent the vehicle belt 12 from interfering with the base anchor member 56 of the support base, which will be described in more detail below, and direct the vehicle belt 12 away from the child when placed in the child seat 10a, 10b.

[0129] 2 and 3, the support base 20 further includes a seat receiver assembly 40 coupled to the base body 22. The seat receiver assembly 40 is configured to receive and couple to at least one child car seat to the support base 20. In one embodiment, multiple child car seats are interchangeably attached to the seat receiver assembly 40. For example, a first child car seat 10a (FIGS. 13A-13B) connectable to the seat receiver assembly 40 is a convertible child car seat, and a second child car seat 10b (FIGS. 14A-14B) connectable to the seat receiver assembly 40 is an infant car seat. As used herein, the term "convertible child car seat" refers to a seat that can be used both rearward and forward facing and is suitable for use by children weighing 5 to 65 pounds and / or up to 49 inches tall. A convertible child car seat may also be referred to herein as an upright child car seat or a toddler car seat. Similarly, as used herein, the term "infant car seat" refers to a seat as defined by those skilled in the art. For example, an infant car seat may be described as a seat for use by infants or children who are too small to use a convertible car seat, and may include a carrying handle to allow the infant car seat to be transported outside of a vehicle, although embodiments in which other types of car seats are alternatively or additionally connectable to the seat receiver assembly 40 are also contemplated herein.

[0130] An example of an infant seat 10a is illustrated in more detail in FIGS. 39A-39C. As illustrated, the infant seat 10a includes a rigid seat shell 40 adapted to receive a child. The seat shell 400 may include a seat portion 402 and a back or upright portion 404 disposed at an angle relative to the seat portion 402. The seat portion 402 and the upright portion 404 may be removably coupled or permanently coupled. In the illustrated non-limiting embodiment, the upright portion 404 and the seat portion 402 are integrally formed as a single, unitary structure. In another alternative, the upright portion 404 may be rotatably coupled to the seat portion 402 such that the upright portion 404 can tilt and recline relative to the seat portion 402.

[0131] As shown, the upright portion 404 of the seat shell 400 faces generally forward and includes an upright support surface 406 that extends from a first end or top 408 of the upright portion 404 to a second, opposite end or bottom (not shown). A first upright side member 412 may be disposed on a first side 414 of the upright support surface 406, and a second upright side member 416 may be disposed on a second, opposite side 418 of the upright support surface 406. Thus, the first and second upright side members 412, 416 form the left and right sides, respectively, of the upright portion 404. As shown, the first and second upright side members 412, 416 extend forward from the upright support surface 406. The first and second upright side members 412, 416 can extend generally perpendicular to the upright support surface 406, or can extend therefrom at another angle, for example, at an angle greater than 90 degrees. Thus, the upright support surface 406 and the first and second upright side members 412, 416 define a back support region or upright support cavity that receives the child's upper body.

[0132] In the illustrated non-limiting embodiment, the upright portion 404 of the seat shell 400 includes a headrest 420. The headrest 420 is attached to or integral with the upright portion 404. The headrest 420 may be stationary or, in some embodiments, configured to move relative to the upright support surface 406. For example, the headrest 420 may be configured to translate relative to the upright support surface 406 between a stowed position and an extended position, allowing adjustment based on the size of the child positioned within the infant seat 10a.

[0133] With continued reference to FIGS. 39A-39C and with further reference to FIG. 40, in one embodiment, a headrest 420 includes a body, identified at 422, and at least one side impact portion 424 attached to the body 422. In the illustrated non-limiting embodiment, the headrest 420 includes one side projection 424 aligned with and attached as an extension of an end 426 of the body 422. The side projection 424 may be located, for example, at the end 426 closest to the vehicle door. However, embodiments including two side projections are also contemplated herein. In such an embodiment, the side projection may be connected to the end 426 of the body 422. The side projection 424 may be permanently fixed to the body 422 or may be removably coupled thereto. In the illustrated non-limiting embodiment, a slot 427 (see FIG. 39C) is formed in the main body 422, for example near the end 426, and the side projection 424 has a connector 428 receivable within the slot 427 for attaching and properly positioning the side projection 424 relative to the main body 422.

[0134] The seat portion 402 includes a seat support surface 430 that faces generally upward and extends from a first end or front 432 to a second end or rear 434 of the seat portion 402. A first seat side member 436 may be disposed on a first side 438 of the seat support surface 430, and a second seat side member 440 may be disposed on a second side 442 opposite the seat support surface 430. The first seat side member 436 and the second seat side member 440 extend upward and form left and right sides of the seat portion 402. The seat support surface 430 and the first and second seat side members 436, 440 combine to define an area 444 in which at least a portion of the child's lower body is received.

[0135] As shown, the seat side members 436, 440 extend at an angle from the seat support surface 430. The angle of the first seat side member 436 relative to the seat support surface 430 may, but need not, be the same as the angle of the first upright side member 412 relative to the upright support surface 406. Similarly, the angle of the second seat portion side member 440 relative to the seat portion support surface 430 may, but need not, be the same as the angle of the second upright side member 416 relative to the upright support surface 406. In one embodiment, the first upright side member 412 and the first seat side member 436 are integrally formed, and the second upright side member 416 and the second seat side member 440 are integrally formed.

[0136] Although at least one child car seat is illustrated and described herein as being mountable to the vehicle seat 2 via the support base 20, it should be understood that in other embodiments, the child car seat may be mountable directly to the vehicle seat 2 without the support base 20. In such embodiments, the child car seat includes one or more openings formed therein that define a belt path for receiving the vehicle belt 12. For example, with reference to the infant car seat 10a shown in FIGS. 39A-43C, although not shown, each upright side member 412, 416 can have an opening formed therein. Alternatively, or in addition, each of the seat side members 436, 440 can have an opening formed therein, such as opening 450. Each of these openings ( ) can be configured to receive a vehicle belt 12 for securing the infant car seat 10a to a forward-facing, high-back configuration of the vehicle seat 2. It should be understood that the infant car seat 10b may have a similar opening, for example formed in the upper edge of its seat shell, for securing the infant car seat 10b to the vehicle seat 2 in a rear-facing configuration.

[0137] When the vehicle belt 12 is installed along such a vehicle belt path, the tension applied to the belt by the vehicle belt's 12 normal buckle 13 or connection and a belt tensioner (not shown) may be sufficient to limit movement of the child safety seat relative to the vehicle seat 2. Alternatively, or additionally, the child safety seat may include one or more anchors or latches (not shown) similar to those used in the LATCH system. Examples of pockets, compartments with movable covers, or other storage locations identified at 452 for such anchors are shown in Figures 43A-43C.

[0138] Although not typically shown, the car seat also includes a harness assembly for restraining a child within the car seat. A typical harness assembly includes two shoulder straps connectable to at least one crotch strap via a buckle. Referring to FIG. 44, in one embodiment, the two shoulder straps can be secured to the car seat 10a, 10b via pulleys and a single strap. A sewn-in splitter can also be used to connect the two shoulder straps to the pulleys with webbing. The length of the shoulder straps and the tightness of the harness assembly can be adjusted with the pulleys.

[0139] As shown in Figures 45 and 46, infant seat 10a can include a metal frame 453 disposed within seat portion 402 of seat shell 400. When infant seat 10a is connected to seat attachment 60, the metal frame of infant seat 10a can be connected to the metal frame of attachment member 202 (Figure 46), which is fixedly connected to the frame of support base 20. In one embodiment, a crotch strap 454 of the harness assembly is connected to metal frame 453 of infant seat 10a via anchor pin 456. Such connection forms a rigid interface between a buckle 458 attached to the crotch strap and the frame of support base 20.

[0140] In one embodiment, the crotch strap 454 of the harness assembly extends through an opening 460 formed in a slider 462 disposed within the seat portion 402. The slider 462 may be movable back and forth relative to the seat shell 400, such as between a first position and a second position. To move the slider 462, a user applies force to the slider 462, thereby disengaging it from the bottom surface of the seat portion 402 and allowing the slider 462 to move freely, for example, forward or backward. When properly positioned, the slider 462 may be biased into engagement with the seat portion 402. The inclusion of the slider 462 allows the position of the buckle 458 attached to the crotch strap 454 to be varied based on the size of the child seated within the infant seat 10a. While the harness assembly and its connections are illustrated and described herein with respect to the infant seat 10a, it should be understood that the infant car seat 10b may have a similar harness assembly or be configured to form a similar rigid connection between the harness assembly and the support base 20.

[0141] In the illustrated non-limiting embodiment, the sheet receiving assembly 40 includes a ramp member 42 generally disposed within an interior 44 of the base body 22 (see FIG. 4). Referring to FIGS. 2-5, the ramp member 42 has a first leg 46a and a second leg 46b offset from one another by a distance. While the first and second legs 46a, 46b are illustrated as being substantially identical, it should be understood that in other embodiments, the first and second legs 46a, 46b may have different configurations. In the illustrated non-limiting embodiment, both the first leg 46a and the second leg 46b each have an upper portion 48 and a lower portion 50. The upper portion 48 and the lower portion 50 may be defined by bends formed in each of the first and second legs 46a, 46b. Thus, the upper portion 48 of each leg 46a, 46b is disposed at a non-parallel angle relative to its lower portion 50. An upper portion 48 of each leg portion 46 a, 46 b may be disposed within the back portion 26 of the base body 22, and a lower portion 50 of each leg portion 46 a, 46 b may be disposed within the seat portion 24 of the base body 22. Because of this positioning, the angle between the upper portion 48 and the lower portion 50 may be the same as or different from the angle formed between the seat portion 24 and the back portion 26 of the base body 22.

[0142] The upper portions 48 of the first and second legs 46 a, 46 b can have a substantially straight configuration, while the lower portions 50 of the first and second legs 46 a, 46 b can have a generally curved configuration. For example, as shown, the lower portions 50 of the first and second legs 46 a, 46 b have a generally concave curvature. However, embodiments in which the lower portions 50 of the first and second legs 46 a, 46 b have different curvatures or straight configurations are also contemplated herein. Furthermore, the tips 52 of the upper portions 48 of each leg 46 a, 46 b can be connected by a connecting member 54. The connecting member 54 can extend generally perpendicular or orthogonal to the upper portions 48 of the legs 46 a, 46 b.

[0143] At least one base anchor member 56 may be fixedly coupled to the tilt member 42. In the illustrated non-limiting embodiment, the base anchor member 56 is fixed to and protrudes from the connecting member 54 of the tilt member 42. The base anchor member 56 is connectable to a corresponding seat anchor member 57 (see FIGS. 19 and 22) of the child car seat when the child car seat is attached to the seat receiver assembly 40. Such a seat anchor member 57 is typically positioned on a surface of the back of the convertible child car seat 10a (e.g., behind a child's back), and thus the base anchor member 56 is connectable thereto when the child car seat is in a forward-facing configuration. This second connection between the base anchor member 56 and the seat anchor member 57 further stabilizes the back of the child car seat. In such an embodiment, the base anchor member 56 may not be connectable to the seat anchor member 57 when the child car seat is in a rear-facing configuration. However, it should be understood that the base anchor member 56 may be suitable for use with a seat anchor member 57 positioned in any position relative to the child car seat.

[0144] An example of a base anchor member 56 is shown in more detail in FIGS. 49A-49B, and an example of a sheet anchor member 57 is shown in more detail in FIGS. 50A-50B. The base anchor member 56 can include a base top hook 58 having an angular configuration, such as an L-shape or a U-shape. The base top hook 58 can be formed from any suitable rigid material, such as steel. The tip 59 of the base top hook 58 is offset from the base body 22 so that a gap or clearance is formed therebetween. Similarly, the sheet anchor member 57 can include a sheet top hook 61 having an angular configuration. While the illustrated sheet top hook 61 has a generally J-shaped configuration, it should be understood that sheet top hooks 61 having any configuration, including a tip 63 that can be received within the clearance defined between the tip 59 of the base top hook 58 and the base body 22, are contemplated herein (see FIGS. 51 and 52).

[0145] Alternatively, or in addition, a portion of the base body 22, such as the back portion 26, may include a base anchor member 56 configured to connect to a corresponding seat anchor member (57) of a child safety seat. In the illustrated non-limiting embodiment, the base anchor member 56 is fixedly attached to the base body 22. The seat anchor member 57 associated with the child safety seat may be fixed or may be movable relative to the child safety seat to accommodate connection with the base anchor member 56 when the child safety seat is in multiple positions, such as a first reclined position and a second reclined position. Alternatively, the base anchor member 56 may be movable relative to the base body 22, and the seat anchor member 57 may be fixedly attached to the child safety seat. The configuration of the seat anchor member 57 and the base anchor member 56 allows the connection between the seat anchor member 57 and the base anchor member 56 to move relative to either the child safety seat or the base body 22 as the child safety seat transitions between the first reclined position and the second reclined position, as described in more detail below.

[0146] Alternatively or additionally, the seat anchor members 57 may be designed with a self-centering feature to facilitate alignment or connection with the base anchor members 56 regardless of the position of the seat anchor member 57 along the path of travel relative to the child seat. In one embodiment, the self-centering feature includes an angled contact surface configured to engage the base anchor member 56 for self-centering about the attachment point of the base anchor member 56. As described in more detail below, the base anchor members 56 typically disengage from their corresponding seat anchor members 57 before the child seat 10 mounted on the seat receiver assembly 40 rotates about an axis relative to the support base 20.

[0147] The support base 20 may further include a tether assembly for securing the support base 20 to the vehicle seat 2. The tether assembly includes a tether support portion 65 that is movable relative to the base body 22 between a first position and a second position. In one embodiment, the tether support portion 65 is disposed on or integrally formed with the tilt member 42, such as at its upper end. Thus, the tether support portion 65 may be movable with the tilt member 42 relative to the base body 22, as described in more detail below. The tether support portion 65 may be formed from any suitable material and, in the illustrated non-limiting embodiment, has a U-shape with both ends of the tether support portion 65 connected to the base top hooks 58 or directly to a portion of the tilt member 42. A tether strap (not shown) is coupled to the support base 20 and extends through an opening 67 formed in the upper surface of the base body 22 or the base anchor member 56, allowing it to be coupled to a portion of the vehicle seat 2. When the tether strap is extended through the opening 67 and connected to the vehicle seat, the tether strap abuts against the tether support portion 65, and at least a portion of the load acting on the tether strap is transmitted to the tether support portion 65 rather than the base body 22.

[0148] 2 and 3, and with further reference to FIGS. 6-7, the seat receiver assembly 40 further includes a seat attachment 60. In the illustrated non-limiting embodiment, the seat attachment 60 includes a support base 62 and a mounting member 64, with the support base 62 positionable in an overlapping arrangement with the mounting member 64. The support base 62 may include two guide rails 66 adapted to receive and couple with corresponding portions of the child car seats 10a, 10b to lock the child car seats to the seat attachment 60. The guide rails 66 may be symmetrical and substantially identical, as shown. In the illustrated non-limiting embodiment, each guide rail 66 includes a first groove 68 and a second groove 70 spaced apart from the first groove 68. The first and second grooves 68, 70 may be recessed in the upper surface of the guide rails 66 and sized to receive and retain portions of components, such as shafts 14, 16 (FIG. 2), located at the bottom or base of the child car seats 10a, 10b. Although not shown, it should be understood that each of the first and second grooves 68, 70 may include a catch that a corresponding latch (not shown) engages to lock the child car seat 10a, 10b to the seat attachment 60.

[0149] As best shown in Figures 2, 3, and 6, an annular or circular collar 72 may protrude from the bottom surface of the support base 62. Additionally, one or more flanges 74 may extend radially outward from the distal end of the collar 72. The flanges 74 may, but need not, extend around the entire circumference of the collar 72. In such an embodiment, the base 76 of the mounting member 64 may also include one or more radially outwardly extending flanges 78. Thus, when the support base 62 is attached to the mounting member 64 in an axially overlapping configuration as shown, at least one flange 78 of the mounting member 64 is disposed within the plane of one or more flanges 74 of the collar 72. Furthermore, the flanges 74, 78 may cooperate to form a flange that extends around the entire circumference of the collar 72.

[0150] The sheet receiving assembly 40 may further include a support plate 80 for attaching the sheet attachment 60 to the base body 22. As shown, the support plate 80 has a central opening 82 formed therein. The collar 72 of the support base 62 and the base 76 of the mounting member 64 both extend through the opening 82 so that the flanges 74, 78 contact the underside of the support plate 80. This engagement between the flanges 74, 78 and the support plate 80 prevents the sheet attachment 60 from separating from the support plate 80.

[0151] As best shown in FIG. 4 , the base body 22 has an opening 84 formed in the upper surface of the seat portion 24. The support plate 80 can be attached to the base body 22 adjacent to or overlapping the opening 84 (see FIG. 1 ). For example, in one embodiment, a portion of the support plate 80, e.g., its first end 86, is receivable within the interior 44 of the base body 22. In the illustrated non-limiting embodiment, a fin 88 (see FIG. 3 ) protruding from the support plate 80 near its first end 86 is configured to contact an adjacent surface of the base body 22, such as the inner surface of the seat portion 24, to limit movement of the support plate 80 relative to the base body 22. In such an embodiment, the contour of the fin 88 can be complementary to the contour of the inner surface of the seat portion 24. However, it should be understood that embodiments in which the support plate 80 is alternatively or additionally coupled to the base body 22 in another suitable manner are also within the scope of the present disclosure.

[0152] When the support plate 80 is attached to the base body 22, the support plate 80 substantially seals the opening 84 of the seat portion 24. Furthermore, the upper surface of the support platform 62, which includes the guide rails 66 for connecting to a child seat, is located vertically above the support plate 80 on the outside of the base body 22.

[0153] In one embodiment, the seat attachment 60 is movably coupled to the support base 20, such as to the tilting member 42. For example, the seat attachment 60 may be rotatably coupled to the tilting member 42. Thus, the seat attachment 60 may be rotatable relative to the tilting member 42, the support plate 80, and the base body 22 between a first rotational configuration, such as a configuration in which the child seat coupled to the seat-receiving assembly 40 is in a forward-facing position (FIG. 13A), and a second rotational configuration, such as a configuration in which the child seat coupled to the seat-receiving assembly 40 is in a rearward-facing position (FIG. 13B) or one or more other configurations (FIG. 14B).

[0154] 5, 7, and 8, in the illustrated non-limiting embodiment, the tilt member 42 includes a mounting bracket 90 coupled to the lower portion 50 of one or both of the first leg 46a and the second leg 46b. A mounting post 92 projects from an upper surface 94 of the mounting bracket 90. The mounting member 64 may similarly include a plate 96 having an opening 98 formed therein, the mounting post 92 being receivable within the opening 98 to define an axis of rotation X for the seat attachment 60. Thus, the connecting support 62 and the mounting member 64 are rotatable together relative to the tilt member 42, the support plate 80, and the base body 22 about axis X.

[0155] In one embodiment, the allowable rotation of the seat attachment 60 about the axis of rotation X varies depending on the child seat connected to it. For example, when a first child seat, such as a convertible child seat 10a, is coupled to the seat attachment 60, the first child seat 10a can rotate about the axis X between a first, forward-facing configuration (FIG. 13A) and a second, rearward-facing configuration (FIG. 13B). The first and second rotation configurations of the first child seat 10a can be positioned 180 degrees apart. When a second child seat, such as an infant child seat 10b, is attached to the seat attachment 60, the second child seat 10b can rotate about the axis of rotation X between a first, rearward-facing configuration (FIG. 14B) and a second, side-facing configuration (FIGS. 14B and 16B). The first and second rotational configurations associated with the second child seat 10b may be spaced approximately 90 degrees apart, or may be any amount less than 180 degrees. Thus, the amount of allowable rotation of the seat attachment 60 when the first child seat 10a is connected to the seat attachment 60 is greater than the amount of allowable rotation of the seat attachment 60 when the second child seat 10b is connected to the seat attachment 60. However, embodiments in which the seat attachment 60 is rotatable in the same manner when both the first and second child seats 10a, 10b are attached thereto are also contemplated herein.

[0156] As previously mentioned, a child car seat, such as the first child car seat 10a, can have a seat anchor member 57 attached to its back. Thus, when the child car seat is in a first rotational configuration, the seat anchor member is connectable to the base anchor member 56. When the child car seat is rotated about an axis relative to the base to a second rotational configuration, the seat anchor member is spaced from the base anchor member 56. Furthermore, the seat anchor member 57 can be configured to automatically align with the base anchor member when the child car seat is rotated from the second rotational configuration to the first rotational configuration.

[0157] Although not shown, a spin lock mechanism is associated with the seat attachment 60 and is operable to selectively lock the seat attachment 60 in one of a plurality of configurations, including a first rotational configuration and a second rotational configuration. When the spin lock mechanism is engaged, rotation of the seat attachment 60 about the rotational axis X is restricted. It should be understood that the spin lock mechanism may be operable to lock the seat attachment 60, and thus the child seat coupled thereto, only in the first and second configurations, or alternatively, at any suitable position along the rotational path between the first and second rotational configurations.

[0158] The spin release actuator 100 may be operable to selectively release the spin lock mechanism, thus allowing rotation of the seat attachment 60 about axis X (see FIGS. 13A and 13B). However, embodiments in which all or at least a portion of the spin release actuator 100 is locally mounted relative to the support base 20 are also contemplated herein.

[0159] 23-27, another example of a seat receiver assembly 40 and a seat attachment 60 is shown. The seat attachment 60 similarly includes a support base 200 positionable to overlap the attachment member 202, as previously described. The support base 200 may include one or more guide rails 204 adapted to receive and couple with corresponding portions of the child car seat 10a, 10b to lock the child car seat to the seat attachment 60. In the illustrated non-limiting embodiment, each guide rail 204 includes a first groove 206 and a second groove 208 spaced apart from one another. The first and second grooves 206, 208 may be formed as recesses in the upper surface of the guide rail 204 sized to receive and retain a portion of the child car seat, such as the shafts 14, 16. The first and second grooves 206, 208 may include catches that are engaged by corresponding latches (not shown) to lock the child car seat 10a, 10b to the seat attachment 60.

[0160] As best shown in FIG. 27 , similar to the previous embodiment, an annular or circular collar 210 extends downwardly from a bottom 212 of the support base 200. In one embodiment, one or more openings 214 are formed in the collar 210. The mounting member 202 can include one or more radially outwardly extending legs 216, each receivable within a corresponding opening 214 in the collar 210 to couple the support base 200 to the mounting member 202. In one embodiment, the mounting member 202 includes a collar 217 from which the legs 216 project outward. The collar 217 has one or more openings 219 formed therein such that the collar 217 is received within the openings 214 and the collar 210 is received within the openings 219 when the support base 200 is coupled to the mounting member 202. Thus, the support base 200 and the mounting member 202 in combination can define a collar that extends around the entire periphery of the seat mounting portion 60.

[0161] In embodiments, a bottom surface of at least one radially outwardly extending leg 216 is disposed generally flush with a corresponding bottom surface of collar 210. However, embodiments in which leg 216 is not flush with the bottom surface of collar 210 are also contemplated herein. Additionally, both collar 210 of support base 200 and leg 216 of mounting member 202 may extend through openings 82 formed in a support plate, such as support plate 80.

[0162] As with the previous embodiment, the seat attachment 60 is movably coupled to the support base 20 via the tilting member 42 or the like. The seat attachment 60 is rotatable relative to the support base 20 about axis X between a plurality of rotational configurations, including a first rotational configuration and a second rotational configuration. With continued reference to FIGS. 28, 29A, and 29B, an example of a locking mechanism 220 operable to selectively limit movement of the seat attachment 60 about an axis is shown. While the locking mechanism 220 is illustrated and described herein with respect to the seat attachment of FIGS. 25A-29B, it should be understood that the locking mechanism 220 may be adapted for use with the seat attachment of FIGS. 2, 3, 6, and 7, or any other suitable seat attachment.

[0163] As shown, the locking mechanism 220 may include a locking member 222 movable between a disengaged position and an engaged position, for example, along an axis oriented substantially perpendicular to the axis of rotation of the seat attachment 60. When the locking member 222 is in the engaged position, the spin lock mechanism prevents rotation of the seat attachment 60. At least one opening 224 ( FIG. 28 ) may be formed in the annular collar 210 of the support base 200. In the illustrated non-limiting embodiment, a first opening 224 is formed in the annular collar 210 of the support base 200 at a first position associated with a first rotational configuration, such as a forward-facing position, and a second opening (not shown) is formed in the annular collar 210 at a second or other position associated with a second rotational configuration, such as a rearward-facing position. The size and shape of the opening 224 are selected so that at least a portion of the locking member 222 can be received therein. In some embodiments, the one or more openings are substantially the same size and / or shape as the portion of the locking member 222 receivable therein.

[0164] 28 , at least a portion of the locking member 222 extends into an opening 224 formed in the annular collar 210. In this configuration, engagement between the locking member 222 and a portion of the seat mounting portion 60, such as a sidewall of the opening 224, limits rotation of the support base 200, and thus the child seat attached thereto, about axis X. Although not shown, a biasing mechanism may be operably coupled to the locking member 222. In such an embodiment, the biasing force of the biasing mechanism may be configured to bias the locking member 222 toward the engaged position.

[0165] One or more actuators are operable to deform the locking member 222 to a disengaged position, for example, by opposing the bias of the biasing member 222, to allow rotation of the seat attachment 60 about the rotation axis X. In one embodiment, an actuator 230 coupled to the locking member 222 is operable to pull the locking member 222 from the engaged position to the disengaged position. Alternatively, or in addition, an actuator 232 coupled to the locking member 222 is configured to push the locking member 222 from the engaged position to the disengaged position.

[0166] 30A-30B, another embodiment of a locking mechanism 220 is shown. As shown, the locking member 222 is attached to the base body 22 and is rotatable about an axis between an engaged or locked position (FIG. 30A) and a disengaged or unlocked position (FIG. 30B). As best shown in FIG. 31, a stationary component, such as a portion of a spin lockout mechanism 240 (described in further detail below) that defines the rotational path of the seat attachment, may be disposed within the support base 20. In the illustrated, non-limiting embodiment, the spin lockout mechanism 240 includes a stationary first spin locking member 244 having a radial flange 245 that includes one or more locking features 247, such as, for example, grooves, recesses, or detents. When the locking member 222 is in the locked position, a portion of the locking member is receivable within the corresponding locking feature 247. The engagement between the locking member 222 and the locking feature 247 limits rotation of the seat attachment 60 in any direction about the axis X. When the locking member 222 is in the disengaged position, the locking member 222 rotates about its axis and moves out of engagement with the locking feature 247. As a result, the seat attachment 60 is free to rotate relative to the support base 20 to a desired position.

[0167] The rotation lock actuator 230 may be operable to deform the lock member 222 to the disengaged position. In the illustrated non-limiting embodiment, operation of the rotation lock actuator 230 applies a direct force to a portion of the lock member 222, causing the lock member 222 to rotate about its axis. Activation of the rotation lock actuator 230 further counteracts the bias of a biasing mechanism 231 operably coupled to the rotation lock actuator. When the actuator is released, the biasing mechanism 231 biases the rotation lock actuator 230 out of engagement with the lock member 222. Furthermore, the overall shape and body of the lock member 222 can be selected such that when the force of the rotation lock actuator is removed therefrom, gravity acting on the lock member 222 causes the lock member to swing about its axis toward the engaged position. The various configurations of the lock mechanism 220 shown and described herein are intended to be exemplary only, and it should be understood that a lock mechanism 220 having any suitable configuration operable to selectively restrict rotation of a seat accessory is within the scope of the present disclosure.

[0168] At least one actuator 230, 232 includes an actuator mechanism 233 accessible to a user for operating the actuator. In the non-limiting embodiment shown in FIGS. 23-24B, 27, 30B-32B, the actuator mechanism 233 is disposed on the seat attachment 60 and is movable about its rotation axis X relative to the support base 20. Thus, when an infant car seat 10b is connected to the seat attachment 60, a user applies a force to the rotation lock actuator 230 via the actuator mechanism 233 to rotate the seat attachment 60 as desired. In embodiments in which an infant seat 10a is connected to the seat attachment, the infant seat 10a may cover the actuator mechanism 233. In such embodiments, a spin actuator 251 integrated into the infant seat 10a may be operably coupled to the actuator mechanism 233 or another portion of the actuator 230 (e.g., via an actuator member 235) such that operation of the spin actuator 251 disposed on the infant seat 10a transforms the lock member 222 from the locked position to the unlocked position.

[0169] In embodiments including multiple actuators 230, 232, the actuation mechanism for each actuator may be located in a variety of locations. For example, the actuation mechanism for a first actuator 230 associated with the locking mechanism 220 may be attached to the support base 20, and the actuation mechanism for a second actuator 232 associated with the locking mechanism 220 may be located on the child car seat 10a, 10b connected to the seat attachment 60. In the non-limiting embodiment shown in FIG. 28 , the actuation mechanism for an actuator, such as the second actuator 232, may be located on the child car seat 10a along the vehicle belt path used to attach the child car seat 10a directly to the vehicle seat 2, without using the support base 20.

[0170] 5, 7, and 8, in the illustrated non-limiting embodiment, the tilt member 42 includes a mounting bracket 90 coupled to the lower portion 50 of one or both of the first leg 46a and the second leg 46b. A mounting post 92 projects from an upper surface 94 of the mounting bracket 90. The mounting member 64 may similarly include a plate 96 having an opening 98 formed therein, the mounting post 92 being receivable within the opening 98 to define an axis of rotation X for the seat attachment 60. Thus, the connecting support 62 and the mounting member 64 are rotatable together relative to the tilt member 42, the support plate 80, and the base body 22 about axis X.

[0171] In one embodiment, the allowable rotation of the seat attachment 60 about the axis of rotation X varies depending on the child seat connected to it. For example, when a first child seat, such as a convertible child seat 10a, is coupled to the seat attachment 60, the first child seat 10a can rotate about the axis X between a first, forward-facing configuration (FIG. 13A) and a second, rearward-facing configuration (FIG. 13B). The first and second rotation configurations of the first child seat 10a can be positioned 180 degrees apart. When a second child seat, such as an infant child seat 10b, is attached to the seat attachment 60, the second child seat 10b can rotate about the axis of rotation X between a first, rearward-facing configuration (FIG. 14B) and a second, side-facing configuration (FIGS. 14B and 16B). The first and second rotational configurations associated with the second child seat 10b may be spaced approximately 90 degrees apart, or may be any amount less than 180 degrees. Thus, the amount of allowable rotation of the seat attachment 60 when the first child seat 10a is connected to the seat attachment 60 is greater than the amount of allowable rotation of the seat attachment 60 when the second child seat 10b is connected to the seat attachment 60. However, embodiments in which the seat attachment 60 is rotatable in the same manner when both the first and second child seats 10a, 10b are attached thereto are also contemplated herein.

[0172] As previously mentioned, a child car seat, such as the first child car seat 10a, can have a seat anchor member 57 attached to its back. Thus, when the child car seat is in a first rotational configuration, the seat anchor member is connectable to the base anchor member 56 or 58. When the child car seat is rotated about an axis relative to the base into a second rotational configuration, the seat anchor member is spaced from the base anchor members 56, 58. Furthermore, the seat anchor member 57 can be configured to automatically align with the base anchor member when the child car seat is rotated from the second rotational configuration to the first rotational configuration.

[0173] Referring again to Figures 28-29B and further to Figures 33A-33C, an example spin lockout mechanism 240 for defining and / or controlling rotation of the seat attachment 60 about axis X is shown. The spin lockout mechanism 240 can be used to control the allowable rotation of the seat attachment 60 relative to the support base 20 based on the type of child car seat 10a, 10b attached thereto. As shown, the spin lockout mechanism 240 can include a spin carriage assembly 242, a first spin lock member 244, and a second spin lock member 246. The first spin lock member 244 is fixedly attached to the support base 20. In one embodiment, the first spin lock member 244 is integrally formed with or fixedly attached to the mounting bracket 90. The spin carriage assembly 242 and the second spin lock member 246 are rotatable with the seat attachment 60. In the illustrated non-limiting embodiment, the spin carriage assembly 242 is integrally formed with the underside of the support base 200. Thus, in some embodiments, the annular collar 210 of the support base 200 may be considered the spin carriage assembly 242. The second spin lock member 246 may be movably coupled to a portion of the seat mount 60, such as the spin carriage assembly 242. Thus, the spin carriage assembly 242 and the second spin lock member 246 are rotatable with the child car seat 10a, 10b attached to the seat mount 60 relative to the first spin lock member 244.

[0174] As shown, the first spin lock member 244 may have a partially circular circumference. For example, the first spin lock member 244 may have a constant radius for at least 200 degrees, and in some embodiments, at least 220 degrees, at least 240 degrees, at least 250 degrees, at least 260 degrees, and at least 270 degrees of the circumference. The remaining portion of the circumference of the first spin lock member 244 has a smaller radius. In one embodiment, the chord portion 248 extends between two endpoints of a circular circumference having a constant radius, and the protrusion 250 extends radially outward from the chord portion 248, e.g., from a center location of the chord portion 248. However, the radius at the protrusion 250 is smaller than the constant radius. In one embodiment, the chord portion 248 has a curved configuration such that the radius of the chord portion 248 gradually decreases from each of the two endpoints of the circular circumference toward the protrusion 250.

[0175] As the spin carriage assembly 242 and second spin lock member 246 rotate with the seat attachment 60 about rotation axis X, the second spin lock member 246 generally engages the outer periphery of the first spin lock member 244. In embodiments in which a first child seat 10a, such as a convertible or infant seat, is connected to the seat attachment 60, the spin carriage assembly 242 and second spin lock member 246 may be arranged in a free configuration. In the free configuration, the spin carriage assembly 242 and second spin lock member 246 are free to rotate 360 ​​degrees about the entire outer periphery of the first spin lock member 244. In embodiments in which a second child seat 10b, such as an infant seat, is coupled to the seat attachment 60, the second spin lock member 246 can be considered to be arranged in a lockable configuration. During rotation of the spin carriage assembly 242 and second spin lock member 246 in the lockable configuration, the engagement member 252 is configured to abut against a side surface 256 of the protrusion 250. As a result, interference between the engagement member 252 and the side surface 256 of the protrusion 250 limits rotation of the second spin lock member 246 to less than 360 degrees. In one embodiment, contact between the engagement member 252 and the side surface 256 of the protrusion 250 limits rotation of the seat attachment 60 to a forward position.

[0176] In the illustrated non-limiting embodiment, the engagement member 252 of the second spin lock member 246 is fixedly attached to a shaft 260. The shaft 260 is rotatable about its longitudinal axis between a locked position and an unlocked position. A biasing mechanism 262, such as a coil spring, can be fixedly attached to the engagement member 252 or another portion of the second spin lock member 246. The biasing force of the biasing mechanism 262 can be configured to bias the shaft 260 about its axis toward the locked position.

[0177] When the engaging member 252 of the second spinlock member 246 is positioned to abut against the circular outer peripheral surface having a constant radius of the first spinlock member 244, the abutment between the engaging member 252 of the second spinlock member 246 and the first spinlock member 244 counters the biasing force of the biasing mechanism 262, regardless of whether the first child car seat 10a or the second child car seat 10b is connected to the seat attachment 60. Therefore, when the engaging member 252 of the second spinlock member 246 abuts against the circular outer peripheral surface having a constant radius of the first spinlock member 244, the shaft 260 is held in the unlocked position.

[0178] As the second spin lock member 246 further rotates about axis X relative to the first spin lock member 244, the engagement member 252 contacts the outer periphery of the chord portion 248 in a direction toward the protrusion 250. Because the radius of the chord portion 248 gradually decreases from its end point toward the protrusion 250, the force exerted by the first spin lock member 244 on the engagement member 252 that counters the biasing force of the biasing mechanism 262 decreases. As a result, the biasing force of the biasing mechanism 262 rotates the shaft 260 and the coupled engagement member 252 about the shaft axis, maintaining contact between the engagement member 252 and the first spin lock member 244.

[0179] When the first child car seat 10a is connected to the seat attachment 60, the first child car seat 10a can be configured to counter the biasing force of the biasing mechanism 262, thereby preventing the second spinlock member 246 from transitioning from the free configuration to the lockable configuration. As shown, the engagement member 252 is positioned radially outward of the protrusion 250 in the free configuration. As a result of this positioning, the second spinlock member 246 is free to rotate about the entire circumference of the first spinlock member 244.

[0180] In one embodiment, at least one detachable lock member 264 is fixed to the shaft 260 of the second spin lock member 246, for example, on the outside of the spin carriage assembly 242. The at least one detachable lock member 264 is therefore configured to rotate together with the shaft 260 and the engagement member 252 about the shaft axis between a locked position and an unlocked position. The first child seat 10a may include not only the shafts 14, 16 located at its bottom as described above, but also an additional intermediate shaft 17 located between the shafts 14, 16. In such an embodiment, a corresponding opening 265 (see FIG. 27) for receiving the intermediate shaft 17 may be formed in the seat mounting portion 60.

[0181] When the first child car seat 10a is coupled to the seat attachment 60, the intermediate shaft 17 of the first child car seat 10a is disposed within the rotational path of the at least one release lock member 264 of the second spin lock member 246. Thus, when the engagement member 252 rotates from the end point of the chord portion 248 toward the protrusion 250, the engagement between the intermediate shaft 17 and the at least one release lock member 264 coupled to the shaft 260 counters the biasing force of the biasing mechanism 262. This engagement limits further rotation of the shaft 260, thereby preventing the second spin lock member 246 from transitioning from the free configuration to the lockable configuration.

[0182] The second child car seat 10b does not include an equivalent intermediate shaft. Thus, when the second child car seat 10b is coupled to the seat attachment 60, the engagement member 252 rotates from the end point of the chord portion 248 toward the protrusion 250, thereby biasing the shaft 260 of the second spinlock member 246 into a lockable configuration via the biasing force of the biasing mechanism 262. In the lockable configuration, the engagement member 252 is biased inward toward the surface of the first spinlock member 244. In this first lockable configuration, the protrusion 250 of the first spinlock member 244 is positioned within the rotational path of the engagement member 252 of the second spinlock member 246, thereby limiting rotation of the second spinlock member 246, spin carriage assembly 242, and seat attachment 60 (including the second child car seat 10b) to one or more positions, such as a forward-facing position. It should be understood that the spin lockout mechanism 240 shown and described herein is intended to be exemplary only, and that any suitable mechanism for controlling rotation of the seat mount 60 about an axis relative to a child seat mounted thereto is within the scope of the present disclosure.

[0183] In one embodiment, separation of the first child seat 10a from the seat attachment 60 is limited based on the position of the first child seat 10a relative to the support base 20. For example, the first child seat 10a may be separable from the seat attachment when the first child seat 10a is disposed in any position relative to the support base 20, except for certain positions, such as when in the forward-facing configuration. In the forward-facing configuration, separation of the first child seat 10a from the seat attachment 60 is prevented by at least one removal lock member 264. As mentioned above, in the forward-facing configuration, the base anchor member 56 of the first child seat 10a is coupled to the corresponding seat anchor member 57 of the support base 20. Therefore, separation of the first child seat 10a from the support base 20 when coupled to the support base 20 in the forward-facing configuration is prevented by locking the at least one removal lock member 264 to the intermediate shaft 17 of the first child seat 10a.

[0184] In one embodiment, the at least one detachment lock member 264 is operable to selectively limit separation of the first child car seat 10a from the seat attachment 60. The second spinlock member 246 is free to rotate relative to the first spinlock member 244 when the first child car seat 10a is coupled thereto. During this rotation, as previously described, the engagement member 252 is configured to be positioned radially outward of the protrusion 250 of the first spinlock member 244 or to contact the radially outer surface 254. As best shown in FIG. 33A , when the first child car seat 10a is positioned in a position other than the specific position in which separation is limited, the shaft 260, and therefore the at least one detachment lock member 264, is in the unlocked position. In one embodiment, when the engagement member 252 of the spin carriage assembly 242 and the second spin lock member 246 is rotated relative to the chord portion 248 of the first spin lock member 244 toward the protrusion 250, the biasing force of the biasing mechanism 262 causes the at least one detachment lock member 264 to at least partially rotate from the unlocked position toward the locked position. This rotation of the at least one detachment lock member 264 can be caused by a decrease in the radius of the first spin lock member 244, resulting in a loss of contact between the engagement member 252 and the first spin lock member 244.

[0185] In the illustrated non-limiting embodiment, the at least one release lock member 264 includes a hook or other engagement feature 266 disposed at its distal end. When the at least one release lock member 264 is rotated toward the locked position, such as by a reduced radius as the chord 248 of the first spin lock member 244, the hook 266 engages the intermediate shaft 17 of the first child seat 10a or a corresponding portion associated with the intermediate shaft 17 (best shown in FIG. 33B). As a result of this engagement, the first child seat 10a cannot be separated from the seat attachment 60 when the engagement member 252 of the second spin lock member 246 is rotated to the chord 248 of the first spin lock member 244, such as when the first child seat 10a is in a forward-facing position. Similarly, when a first child seat 10a connected to the seat attachment 60 is rotated away from the forward-facing position, the first child seat 10a is considered to be in the second rotated configuration as soon as the engagement feature 266 disengages or separates from the first child seat 10a. Although the at least one removal locking member 264 is illustrated and described herein as being operable to prevent separation of the first child seat 10a from the seat attachment 60 when in the forward-facing position, it will be appreciated that the seat attachment 60 may be designed to prevent separation of the first child seat 10a therefrom in alternative or additional positions relative to the support base 20.

[0186] 1A-5, in one embodiment, the tilting member 42 is movable, e.g., translatable, relative to the base body 22 between a first position, such as a reclined position, and a second position, such as a tilted position. However, it should be understood that both the first and second positions may be tilted positions, with varying degrees of tilt. In the illustrated non-limiting embodiment, the connecting member 54 of the tilting member 42 is generally adjacent to or flush with the upper end 101 of the back portion 26 of the base body 22 when in the first position. Similarly, when in the second position, the tilting member 42 protrudes through an opening 103 formed in the upper end 101 of the back portion 26 such that the connecting member 54 is spaced from the end of the back portion 26.

[0187] 9 and 10 , in the illustrated non-limiting embodiment, the tilting member 42 includes a frame having one or more legs 46. As shown, at least one of the first leg 46 a and the second leg 46 b of the tilting member 42 has one or more pins 102 protruding outwardly therefrom. While two pins 102 ( FIG. 10 ) are shown protruding from each leg 46 a, 46 b (center and end), it should be understood that embodiments having only a single pin or more than two pins are within the scope of the present disclosure. Furthermore, while each of the pins 102 is illustrated as being located at the lower portion 50 of each leg 46 a, 46 b disposed within the seat portion 24 of the base body 22, in other embodiments, one or all of the pins 102 may extend from the upper portion 48 of the leg 46 a, 46 b.

[0188] For example, referring to the embodiment of the ramp member 42 illustrated in FIG. 38 , the ramp member 42 is slidably coupled to the support base 20 at a number of different positions. A first slide pin connection can be located near the top end of the back portion 26 of the support base 20, and a second slide pin connection can be located near the center of the support base 20, for example, near the interface between the seat portion 24 and the back portion 26 of the base body 22. In one embodiment, a roller 111 can be attached to or near the end of the ramp member 42 near the stability leg 32. In such an embodiment, the roller 111 can be configured to roll along or engage with a ramp or track portion located on an adjacent surface of the base body 22.

[0189] A plurality of travel brackets 104 are disposed within the interior 44 of the base body 22, such as adjacent a surface of at least one of the legs 46 a, 46 b. The travel brackets 104 may be secured to the base body 22. While the brackets 104 are illustrated as separate components disposed within the interior 44 of the base body 22, it should be understood that embodiments in which the travel brackets 104 are integrally formed with the base body 22 are also contemplated herein. The travel brackets 104 may have at least one elongated slot 106 formed therein, and a corresponding pin 102 of the ramp member 42 is receivable within each slot 106. Positioning the pin 102 within the slot 106 allows the force exerted by the vehicle belt 12 on the base body 22 to be directly transferred to the ramp member 42. The slot 106 defines a travel path for the ramp member 42 relative to the base body 22. Thus, in the illustrated non-limiting embodiment, when the pin 102 is positioned adjacent the first end 108 of each of the slots 106, the tilt member 42 is in a first or reclined position, and when the pin 102 is positioned adjacent the second, opposite end 110 of each of the slots 106, the tilt member 42 is in a second or tilted position.

[0190] It should be understood that the pin and slot engagement described herein is intended as an example only, and that any configuration that allows movement of the sheet receiving assembly 40 relative to the base body 22 is within the scope of the present disclosure. For example, in one embodiment, the legs 46 a, 46 b of the ramp member 42 have one or more rollers configured to engage a curved surface of the base body 22 or a component disposed within the interior 44 of the base body 22.

[0191] 11A-12B, an alternative or additional connection between the sheet receiving assembly 40 and the base body 22 is illustrated. As shown, at least one rib 83, e.g., a plurality of ribs, projects upward from the upper surface of the fin 88 of the support plate 80. The rib 83 may, but need not, extend beyond the end 85 of the support plate 80. Furthermore, the configuration of the ribs 83 may be substantially identical or different. In the illustrated non-limiting embodiment, the plurality of ribs 83 are spaced apart from one another to define slots 87 between adjacent ribs 83. As best shown in FIG. 11B, the inner surface 89 of the base body 22 facing the fin 88 includes one or more protrusions 91 slidably receivable within the one or more slots 87 defined by the ribs 83. In embodiments including multiple protrusions 91, the protrusions 91 may be substantially identical or different. Additionally, the protrusions 91 may be axially spaced apart on the inner surface 89 in one or more directions such that two or more protrusions 91 are receivable within the same slot 87. However, in other embodiments, both the upper surfaces of the fins 88 and the corresponding inner surface 89 of the base body 22 may be substantially smooth. In such embodiments, the upper surfaces of the fins 88 may be spaced apart from the inner surface 89 of the base body 22 by a gap or clearance such that the support plate 80 is free to move with the ramp member 42 relative to the base body 22.

[0192] 12A and 12B, as the tilting member 42, and thus the support plate 80 and the seat section attachment 60, translate between the first position (FIG. 12A) and the second position (FIG. 12B), the at least one protrusion 91 remains disposed within the corresponding slot 87, thereby limiting lateral movement of the seat section receiving assembly 40. Furthermore, this engagement between the at least one slot 87 and the protrusion 91 causes the force of the vehicle belt to be transmitted directly by the base body 22 to the seat receiving assembly 40.

[0193] Furthermore, it should be understood that because the seat attachment 60 is coupled to the tilting member 42 via the mounting post 92, the seat attachment 60 and the child seat attached to the seat attachment 60 can move with the tilting member 42 relative to the support base 20.

[0194] The tilting member 42 is transformable between a first position (FIGS. 13A, 13B, 14A, and 14B) and a second position (FIGS. 15A, 15B, 16A, and 16B) regardless of the rotational position of the seat attachment 60 relative to the base body 22 and the tilting member 42. For example, the tilting member 42 may be movable when the seat attachment 60 is in any position throughout its 360-degree rotation. Similarly, the seat attachment 60 may be rotatable about axis X regardless of the position of the tilting member 42 relative to the base body 22. As shown, either of the child seats 10a, 10b can be tilted when in a first forward-facing configuration, a second rearward-facing configuration, or any position therebetween. Furthermore, because the inclined member 42 is positioned within the interior 44 of the base body 22 and is separated from the belt tensioner 35 and the belt receiving path, the inclined member 42 is movable between the first position and the second position without affecting the position of the vehicle belt on the belt receiving path and without affecting the tension applied to the vehicle belt by the belt tensioner 35.

[0195] In the illustrated non-limiting embodiment best shown in FIG. 9 , the angled member 42 includes a plurality of angled retaining members 112, for example, arranged to vertically overlap the lower portions 50 of the legs 46 a, 46 b, respectively. The end 114 of the angled retaining member 112 located closest to the mounting bracket 90 can have a complementary contour to the periphery of the collar 72 or flanges 74, 78. While each angled retaining member 112 is illustrated as a separate component, embodiments in which each end 114 cooperates or is joined to define a ring that extends substantially the entire periphery of the collar or flange 74, 78 are also within the scope of this disclosure.

[0196] When the tilt member 42 is transformed from a first or reclined position to a second or tilted position, an end 114 of the tilt retaining member 112 located on a first side of the collar 72 is configured to engage a portion of the flanges 74, 78 of the seat attachment 60 to prevent lateral movement of the seat attachment 60. Similarly, when the tilt member 42 is transformed from a reclined position to a tilted position, an end 114 of the tilt retaining member 112 located on a second side of the collar 72 is configured to engage a portion of the flanges 74, 78 of the seat attachment 60 to prevent lateral movement of the seat attachment 60. For example, in embodiments in which the seat attachment 60 is positioned in either a forward-facing or a rear-facing configuration, the tilt retaining member 112 is configured to engage at least one flange 78 of the attachment member 64 to limit undesired movement of the seat attachment 60. However, embodiments are also contemplated herein in which one or more angled retaining members 112 are alternatively or additionally configured to engage flange 74 of collar 72 when seat attachment 60 is in either the forward-facing or rearward-facing configuration. It should also be understood that angled retaining member 112 may be configured to contact one or both flanges 74, 78 based on the relative position of seat portion attachment 60.

[0197] Additionally, because the opening 82 in the support plate 80 is substantially the same size as the diameter of the collar 72, in some embodiments, movement of the seat mounting portion 60 due to movement of the ramp member 42 may cause a similar movement of the support plate 80 relative to the base body 22. However, by forming the support plate 80 with dimensions larger than the opening 84 formed in the base body 22, the opening 84 remains covered regardless of the position of the support plate 80.

[0198] The tilt locking mechanism is associated with the tilt member 42 and is operable to selectively lock the tilt member 42 in one of a plurality of configurations, including a first reclined configuration and a second reclined configuration. When the tilt locking mechanism is engaged, movement of the tilt member 42 relative to the support base 20 is restricted. It should be understood that the tilt locking mechanism may be operable to lock the tilt member 42 in only one of the reclined and reclined positions. However, in other embodiments, the tilt locking mechanism is configured to lock the tilt member 42 at any suitable position along the path of movement between the reclined and reclined positions to achieve various degrees of tilt of the seat mounting portion 60.

[0199] 35-37, an example of a tilt lock mechanism 300 is shown. As shown, the tilt lock mechanism 300 includes a housing 302, a locking pin 304 movable relative to the housing 302 between an engaged position and a disengaged position, and a reclining member 306 operably coupled to the locking pin 304. The tilt lock mechanism housing may be secured to a portion of the moving bracket 104, such as at a position offset from the slot 106. The reclining member 306 includes a post or pin disposed within an elongated slot 308 formed in the housing 302. In the illustrated non-limiting embodiment, the slot 308 is disposed obliquely relative to the path of movement of the locking pin 304.

[0200] As shown, the locking bracket 310 can be disposed between the mounting bracket 104 and a surface of the leg 46a of the tilting member 42. Accordingly, the pin 102 can be formed as part of the locking bracket 310 or can extend through an opening formed in the locking bracket 310. The locking bracket 310 has a plurality of locking openings 312 formed therein. It should be understood that the plurality of locking openings 312 includes a first locking opening associated with the fully reclined position and a second locking opening associated with the fully reclined position. The plurality of locking openings 312 can further include one or more openings disposed between the first locking opening and the second locking opening associated with at least one intermediate position of the tilting member 42.

[0201] The tilt locking mechanism 300 is positioned so that the locking pin 304 is generally aligned or disposed in a plane that includes the plurality of locking openings 312. Reaching of the locking pin 304 within one of the plurality of locking openings 312 restricts movement of the locking bracket 310, and therefore the tilting member 42, relative to the mounting bracket 104 and base body 22. As the pin 102 translates within the slot 106, the locking bracket 310 moves relative to the tilt locking mechanism 300, sequentially aligning different ones of the plurality of locking openings 312 with the locking pin 304 along the path of tilting movement.

[0202] 37 , tilt release actuator 320 is operable to selectively disengage tilt lock mechanism 300, thereby allowing movement of tilt member 42 relative to support base 20. In embodiments, tilt release actuator 320 is operable to disengage lock pin 304 from one of a plurality of lock openings 312 formed in lock bracket 310, thereby allowing movement of lock bracket 310 coupled to tilt member 42 relative to mounting bracket 104. In one embodiment, tilt release actuator 320 is operably coupled to recliner member 306 by a cable or tension member 322. In response to operation of tilt release actuator 320, recliner member 306 is configured to translate within slot 308 formed in housing 302. This movement of recliner member 306 moves lock pin 304 out of the plane of lock bracket 310, thereby separating lock pin 304 from the corresponding lock opening 312. It should be understood that the tilt lock mechanism 300 and tilt release actuator 320 shown and described herein are intended as examples only, and that any lock mechanism or release actuator having any other suitable configuration is within the scope of the present disclosure.

[0203] Although the input 116 associated with operating the tilt release actuator is shown as being located, for example, on the support plate 80 near the second end of the seat portion 24 of the base body 22, in other embodiments the input may be located at locations around the support base 20. For example, in the non-limiting embodiment of FIGS. 32B and 39A-39C, the operating input 116 for the tilt release actuator 320 is located on a side of the base body 22 that is accessible when both the first child seat 10a and the second child seat 10b are coupled to the seat attachment 60.

[0204] The support base 20 described herein provides the advantage of being suitable for use with multiple interchangeable child seats, allowing the same base to be used with different seats as a child grows. Additionally, the support base 20 allows the rotation configuration and tilt of each child seat to be adjusted relative to the base body 22 and the vehicle seat.

[0205] Embodiment 1. A support base for a child restraint system suitable for placement on a vehicle seat, the child restraint system including an infant car seat and a convertible car seat, the support base comprising: a base body; a seat receiving assembly, the support base comprising: a tilting member movably attached to the base body, the tilting member being movable along a tilting path between a first position and a second position; and a seat mounting fixture rotatably connected to the tilting member, the seat mounting fixture being rotatable relative to the tilting member between a first rotational configuration and a second rotational configuration.
