[0198] The present disclosure provides a detailed description of one or more embodiments of the disclosed devices and methods by way of example and not limitation with reference to the accompanying drawings.

[0199] Referring now to FIG. 1, an example of a support base 20 for use with a child restraint system and configured to receive a child safety seat is illustrated according to an embodiment. The support base 20 may be removably secured to a vehicle seat 2( Figure 17 ), for example via a latch or anchoring mechanism not shown in the figures. Such a latch or anchoring system is often referred to as the "Lower Anchors and Tethers for Children", e.g., the LATCH system. Alternatively or additionally, as will be described in more detail below, the support base 20 may be removably secured to the vehicle seat 2 via a vehicle seat belt 12 associated with the vehicle seat 2 (see Figure 18 ).

[0200] As shown, the support base 20 includes a base body 22 having a seat portion 24 and a rear portion 26. Suitable materials for manufacturing the base body 22 include, but are not limited to, rigid plastics or composite materials. Although the seat portion 24 and the rear portion 26 are illustrated as being integrally formed as a single unit, embodiments in which the seat portion 24 and the rear portion 26 are separate components that are removably or permanently attached together are also within the scope of the present disclosure. The seat portion 24 has a bottom surface 28 adapted to be placed on a support surface, such as a vehicle seat (see Figure 17 ). The rear portion 26 may be disposed at a first end 30 of the seat portion 24 and extend angularly relative to the seat portion. In the illustrated non-limiting embodiment, the rear portion 26 is oriented at an angle between about 75 degrees and about 120 degrees relative to the bottom surface 28 of the seat portion 24. However, it should be understood that embodiments in which the angle formed between the rear 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.

[0201] For example, in the illustrated non-limiting embodiment, a stability leg 32 having a fixed or adjustable length is connected to a portion of the base body 22, such as a second opposite end 34 of the seat portion 24. The stability leg 32 may rotate or fold between an extended configuration ( Figure 1A ) and a retracted configuration ( Figure 1B ), in the extended configuration, the stability leg 32 abuts against the vehicle floor, and in the retracted configuration, the stability leg 32 is stowed under or within the seat portion 24 of the support base 20. When in the retracted configuration, the stability leg may protrude slightly from the bottom surface 28 of the seat portion 24 to facilitate the use of the stability leg 32 during the installation of the support base 20 around the vehicle seat 2.

[0202] Reference Figure 47A , in an embodiment, the rotational axis A of the stability leg 32 can be located within the plane defined by the bottom surface 28 of the seat portion 24. In other embodiments, the rotational axis A of the stability leg 32 can be vertically offset from the bottom surface of the seat portion 24. For example, as Figure 47B shown, the rotational axis can be generally centered between the upper surface of the seat portion 24 and the bottom surface 28. However, it should be understood that stability legs having a rotational axis at any position between the upper surface and the bottom surface 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.

[0203] Continuing to refer Figure 1A , and additionally referring Figures 2 - 4 to FIGS. 8 and 16, the support base 20 can include a seat belt pretensioner 35 coupled to the base body 22. In the illustrated non-limiting embodiment, a recess 36 formed in the base body 22 extends from the seat portion 24 into the rear portion 26 and the seat belt pretensioner 35 can be received within the recess 36. However, it should be understood that embodiments in which the recess 36 is formed only in the rear portion 26 of the base body 22 are also contemplated herein. The profile of the seat belt pretensioner 35 can be complementary to the profile of the recess 36 such that substantially the entire seat belt pretensioner 35 can be received within the recess 36. A vehicle seat belt 12 associated with a vehicle seat on which the support base 20 can be positioned above can be arranged along a seat belt receiving path defined between an outer surface or a top surface 38 of the base body 22 (e.g., the rear portion 26 of the base body 22) and the seat belt pretensioner 35. In an embodiment, the seat belt pretensioner 35 can be selectively moved relative to the base body 22 to adjust the tension applied to the vehicle seat belt 12 along the vehicle seat belt receiving path. For example, the seat belt pretensioner 35 can be configured to pivot about at least one axis to selectively pinch a portion of the vehicle seat belt 12 sandwiched between the seat belt pretensioner 35 and the recess 36 to couple the support base 20 to the vehicle seat belt 12, thereby restricting movement of the support base 20 relative to the vehicle seat.

[0204] In Figures 2 - 4 , 8 and 16 of the non-limiting embodiment, the seat belt pretensioner 35 is formed of a single piece that is pivotally connected to the support base 20 at its first end. However, in other embodiments, as Figure 20A and 20BAs shown, the seatbelt pretensioner 35 can be an assembly that includes a plurality of pretensioning members operatively coupled together. In the illustrated non-limiting embodiment, the seatbelt pretensioner 35 includes a first pretensioning member 130 movably coupled to the support base 20 at its first end 132 and a second pretensioning member 134 movably coupled to the first pretensioning member 130, for example, at its second opposite end 136. Although the first pretensioning member 130 is shown as being rotatably coupled to the support base 20 and the second pretensioning member 134 is shown as being rotatably coupled to the first pretensioning member 130, embodiments in which one or both of the first pretensioning member 130 and the second pretensioning member 134 can move in another manner are also contemplated herein. Additionally, embodiments in which the second pretensioning member 134 is movably directly coupled to the support base 20 rather than the first pretensioning member 130 are also within the scope of the present disclosure.

[0205] In the unlocked position, as Figure 20B shown, the first pretensioning member 130 of the seatbelt pretensioner 35 rotates away from the recess 36, and the second pretensioning member 134 is arranged at a non-parallel angle to the first pretensioning member 130. In such embodiments, a respective biasing mechanism (not shown) can be associated with each of the respective rotational axes of the first pretensioning member 130 and the second pretensioning member 134. In the locked position, the first pretensioning member 130 and the second pretensioning member 134 are arranged generally parallel to each other. In the illustrated non-limiting embodiment, the first pretensioning member 130 has a recess 138 formed in its first surface 140 (e.g., a surface configured to face a seat that can be received on the support base 20). The size of the recess 138 can be complementary to the second pretensioning member 134 such that the second pretensioning member 134 can be nested within the recess 138 of the first pretensioning member 130. In such embodiments, the surface 142 of the second pretensioning member 134 that faces the seat that can be received on the support base can be generally flush with the first surface 140 of the first pretensioning member 130. In other embodiments, a recess can be formed in the rear surface of the second pretensioning member 134 such that the first pretensioning member 130 can be nested within the second pretensioning member 134.

[0206] When in the locked position, as Figure 20AAs shown, the second tensioning member 134 is arranged parallel to the first tensioning member 130. The distal end 144 of the second tensioning member 134 can be selectively coupled to the first tensioning member 130, for example, via a locking mechanism. In the illustrated non-limiting embodiment, the locking mechanism includes a spring-biased first feature 146 that is complementary to a corresponding second feature 148 disposed at the first tensioning member 130 and is configured to engage with the second feature. The first feature 146 can be a tooth or tab biased to a position where the tooth projects beyond the distal end 144 of the second tensioning member 134. As shown, when the seatbelt pretensioner 35 is in the locked position, a portion of the first feature 146 is accessible to the user. The user can thus apply a force to the accessible portion such that the first feature 146 retracts toward the distal end 144 and disengages from the second feature 148, thereby disengaging the distal end 144 of the second tensioning member 134 from the first tensioning member 130. It should be understood that in other embodiments, the feature of the locking mechanism formed at the first tensioning member 130 can alternatively or additionally be moved by the user to selectively unlock the seatbelt pretensioner 35.

[0207] In an embodiment, the second tensioning member 134 has a tab or engagement member 150 projecting therefrom. Although the engagement member 150 is illustrated as being disposed near the end 136 of the second tensioning member 134, embodiments in which the engagement member 150 is disposed at another location on the second tensioning member 134 are also within the scope of the present disclosure. When the seatbelt pretensioner 35 is in the locked configuration, for example, when the seatbelt pretensioner 35 is positioned within the recess 36, the engagement member 150 can be received within a corresponding opening 152 formed in a surface of the support base 20 (adjacent to and in some embodiments defining the recess) adjacent the recess 36. In such embodiments, during the locking operation, the first tensioning member 130 pivots toward the recess 36. Once properly positioned, rotation of 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 can rotate relative to both the first tensioning member 130 and the support base 20 similar to a lever. When the vehicle seatbelt 12 is disposed between the recess 36 and the first tensioning member 130 of the seatbelt pretensioner 35, the mechanical advantage of this lever-type configuration reduces the force applied by the user to move the seatbelt pretensioner 35 to the locked position.

[0208] In an embodiment, at Figures 21A - 21CBest shown in, one or more seat belt guides 160 may be positioned around the support base 20, such as at its rear portion 26. Although generally identical seat belt guides 160 are illustrated as being disposed at opposite sides of the rear portion 26, it should be understood that embodiments having a single seat belt guide are within the scope of the present disclosure. Additionally, in embodiments including multiple seat belt guides 160, the seat belt guides may have different configurations and / or may be arranged at different vertical and lateral positions relative to the vehicle seat belt path with respect to the support base 20. As shown, the seat belt guide 160 may include a slot 162 connected to an internal opening 164 for receiving a portion of the vehicle seat belt 12 therein. At least one seat belt guide 160 is positioned to maintain the portion of the vehicle seat belt 12 not held in place by the seat belt pretensioner 35 outside of the area associated with the seat that may be received on the support base 20. For example, at least one seat belt guide 160 may also assist in aligning the vehicle seat belt 12 relative to the support base 20, keeping the vehicle seat belt 12 away from the base anchoring member 56 that interferes with the support base, as described in more detail below, and keeping the vehicle seat belt 12 away from the child when positioned on the child seats 10a, 10b.

[0209] Reference Figure 2 and 3 , the support base 20 further includes a seat receiving assembly 40 coupled to the base body 22. The seat receiving assembly 40 is configured to receive at least one child seat and couple it to the support base 20. In an embodiment, multiple child seats may be interchangeably mounted to the seat receiving assembly 40. For example, a first child seat 10a ( Figures 13A - 13B ) that may be connected to the seat receiving assembly 40 is a convertible child seat, and a second child seat 10b ( Figures 14A - 14B ) that may be connected to the seat receiving assembly 40 is an infant child seat. As used herein, the term "convertible child seat" refers to a seat that may be used in both rearward and forward directions, such as being suitable for a child weighing between 5 pounds and 65 pounds and / or up to 49 inches in height. The convertible child seat may also be referred to herein as an upright child seat or a toddler seat. Similarly, as used herein, the term "infant child seat" refers to such a seat as would be defined by one of ordinary skill in the art. For example, an infant child seat may be described as a seat for an infant or child too young to use a convertible child seat and may include a carrying handle to allow for portability of the infant child seat outside of the vehicle. However, embodiments are also contemplated herein where another type of child seat may alternatively or additionally be connected to the seat receiving assembly 40.

[0210] In Figures 39A - 39CAn example of the toddler seat 10a is described in more detail below. As shown, the toddler seat 10a includes a rigid seat shell 400 adapted to receive a child. The seat shell 400 may include a seat portion 402 and a backrest 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 detachably coupled, or alternatively, may be permanently coupled. In the illustrated non-limiting embodiment, the upright portion 404 and the seat portion 402 are integrally formed as a single unitary body. In another alternative aspect, the upright portion 404 may be rotatably connected to the seat portion 402 such that the upright portion 404 can be tilted and reclined relative to the seat portion 402.

[0211] As shown, the upright portion 404 of the seat shell 400 includes an upright support surface 406 that generally faces forward and 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 at a first side 414 of the upright support surface 406 and a second upright side member 416 may be disposed at a second, opposite side 418 of the upright support surface 406. Thus, the first upright side member 412 and the second upright side member 416 respectively form the left and right sides of the upright portion 404. As shown, the first upright side member 412 and the second upright side member 416 extend forward from the upright support surface 406. The first upright side member 412 and the second upright side member 416 may generally extend orthogonally to the upright support surface 406, or alternatively, may extend therefrom at another angle, such as an angle greater than 90°. Thus, the upright support surface 406, along with the first upright side member 412 and the second upright side member 416, defines a backrest area or upright support cavity for receiving the upper body of a child therein.

[0212] 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, may be 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 retracted position and an extended position, thereby allowing adjustment based on the size of the child positioned within the toddler seat 10a.

[0213] Continuing to refer Figures 39A - 39C And further referring Figure 40, in an embodiment, the headrest 420 includes a body identified as 422 and at least one side impact portion 424 mounted to the body 422. In the illustrated non - limiting embodiment, the headrest 420 includes one side impact portion 424 that is mounted to align with and extend as an extension of an end 426 of the body 422. For example, the side impact portion 424 may be located on the end 426 closest to the vehicle door. However, embodiments including two side impact portions are also contemplated herein. In such embodiments, the side impact portions may be connected to the end 426 of the body 422. The side impact portion 424 may be permanently attached to the body 422 or, alternatively, may be detachably connected to the body. In the illustrated non - limiting embodiment, a slot 427 (see Figure 39C ) is formed in the body 422, such as near the end 426, and the side impact portion 424 has a connector 428 that can be received within the slot 427 to attach and properly position the side impact portion 424 around the body 422.

[0214] The seat portion 402 includes a seat support surface 430 that generally faces upward and extends from a first end or front portion 432 of the seat portion 402 to a second end or rear portion 434. A first seat side member 436 may be disposed at a first side 438 of the seat support surface 430 and a second seat side member 440 may be disposed at a second, opposite side 442 of the seat support surface 430. The first seat side member 436 and the second seat side member 440 extend upward and form the left and right sides of the seat portion 402. The seat support surface 430, along with the first seat side member 436 and the second seat side member 440, together define an area 444 that can internally receive at least a portion of a child's lower body.

[0215] 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 side member 440 relative to the seat 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 an 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.

[0216] It should be understood that although at least one child seat is described and illustrated herein as being mountable to a vehicle seat 2 via a support base 20, in other embodiments, the child seat may be directly mounted to the vehicle seat 2 without the presence of the support base 20. In such embodiments, the child seat includes one or more openings formed therein and defining a seat belt path for receiving a vehicle seat belt 12. For example, referring to Figures 39A - 43C the toddler seat 10a shown in, although not shown, each of the upright side members 412, 416 may have an opening formed therein. Alternatively or additionally, each of the seat side members 436, 440 may have an opening, such as opening 450 formed therein. Each of these openings may be configured to receive the vehicle seat belt 12 to secure the toddler seat 10a to the vehicle seat 2 in a forward-facing high-back configuration. It should be understood that the infant car seat 10b may have similar openings, such as formed at the upper edge of its seat shell, to secure the infant car seat 10b to the vehicle seat 2 in a rear-facing configuration.

[0217] When the vehicle seat belt 12 is installed along this vehicle seat belt path, the normal buckle 13 or connector of the vehicle seat belt 12 and the tension applied to the seat belt by a seat belt pretensioner (not shown) may be sufficient to restrict movement of the child seat relative to the vehicle seat 2. Alternatively or additionally, the child seat may include one or more anchors or latches (not shown) similar to those used in a latching system. For such anchors, examples of recesses, compartments with movable covers, or other storage locations (identified as 452) are described in Figures 43A - 43C the seat shell, or other storage locations (identified as 452).

[0218] Although not generally shown, the child seat further includes a harness assembly for restraining a child within the child seat. A typical harness assembly includes two shoulder straps that may be connected via a buckle to at least one crotch strap. Referring to Figure 44 in an embodiment, the two shoulder straps may be anchored to the child seats 10a, 10b via pulleys and a single strap. A stitching separator may be used to connect the two shoulder straps to the pulley using a single webbing. The length of the shoulder straps and the tightness of the harness assembly may be adjusted via the pulleys.

[0219] As Figure 45 and 46 shown in, the toddler seat 10a may include a metal frame 453 disposed within the seat portion 402 of the seat shell 400. When the toddler seat 10a is coupled to the seat attachment 60, the metal frame of the toddler seat 10a may be connected to the metal frame of the attachment member 202 ( Figure 46), and the metal frame is in turn rigidly connected to the frame of the support base 20. In an embodiment, the crotch strap 454 of the protective strap assembly is connected to the metal frame 453 of the infant seat 10a via an anchor pin 456. This connection creates a rigid interface between the buckle 458 attached to the crotch strap and the frame of the support base 20.

[0220] In an embodiment, the crotch strap 454 of the protective strap assembly extends through an opening 460 formed in a slider 462 disposed within the seat portion 402. The slider 462 is movable relative to the seat shell 400, e.g., forward and backward between a first position and a second position. To move the slider 462, a user applies a force to the slider 462, thereby disengaging the slider from the bottom of the seat portion 402 such that the slider 462 is free to move, e.g., forward or backward. Once properly positioned, the slider 462 can be biased to engage 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 changed based on the size of the child sitting within the infant seat 10a. Although the protective strap assembly and its connections are described and illustrated herein with respect to the infant seat 10a, it should be understood that the infant seat 10b may have a similar protective strap assembly or may be configured to form a similar rigid connection between the protective strap assembly and the support base 20.

[0221] In the illustrated non-limiting embodiment, the seat stowage assembly 40 includes an inclined member 42 generally disposed within the interior 44 of the base body 22 (see Figure 4 ). Referring to Figures 2 - 5 , the inclined member 42 has a first leg 46a and a second leg 46b that are offset from each other by a certain distance. Although the first leg 46a and the second leg 46b are illustrated as being generally the same, it should be understood that in other embodiments, the configuration of the first leg 46a and the second leg 46b may vary. 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 a bend formed in each of the first leg 46a and the second leg 46b. Thus, the upper portion 48 of each of the legs 46a, 46b is arranged at a non-parallel angle relative to its lower portion 50. The upper portion 48 of each leg 46a, 46b may be disposed within the rear portion 26 of the base body 22 and the lower portion 50 of each leg 46a, 46b may be disposed within the seat portion 24 of the base body 22. Due to 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 rear portion 26 of the base body 22.

[0222] The upper portions 48 of the first leg 46a and the second leg 46b may have a generally linear configuration and the lower portions 50 of the first leg 46a and the second leg 46b may have a generally curved configuration. For example, as shown, the lower portions 50 of the first leg 46a and the second leg 46b have a generally concave curvature. However, embodiments in which the lower portions 50 of the first leg 46a and the second leg 46b have different curvatures or linear configurations are also contemplated herein. Additionally, the distal ends 52 of the upper portions 48 of each leg 46a, 46b may be joined by a connecting member 54. The connecting member 54 may extend generally perpendicular or orthogonal to the upper portions 48 of the legs 46a, 46b.

[0223] At least one base anchoring member 56 may be fixedly connected to the recline member 42. In the illustrated non-limiting embodiment, the base anchoring member 56 is attached to the connecting member 54 of the recline member 42 and projects therefrom. When the child seat is attached to the seat storage assembly 40, the base anchoring member 56 may be connected to a corresponding seat anchoring member 57 of the child seat (see Figure 19 and Figure 22 ). Such seat anchoring members 57 are typically disposed at the surface of the rear portion of the convertible child seat 10a (e.g., behind the child's back), and thus the base anchoring member 56 may be connected to the seat anchoring member when the child seat is in the forward configuration. This second connection between the base anchoring member 56 and the seat anchoring member 57 further stabilizes the rear portion of the child seat. In such embodiments, the base anchoring member 56 may not be connectable to the seat anchoring member 57 when the child seat is in the rearward configuration. However, it should be understood that the base anchoring member 56 may be adapted to be used with seat anchoring members 57 disposed at any location around the child seat.

[0224] In Figures 49A - 49B an example of the base anchoring member 56 is described in more detail, and in Figures 50A - 50B an example of the seat anchoring member 57 is described in more detail. The base anchoring member 56 may include a base top hook 58 having an angular configuration, such as an L or U shape. The base top hook 58 may be formed of any suitable rigid material, such as steel. The distal end 59 of the base top hook 58 is offset from the base body 22 such that a space or gap is formed therebetween. Similarly, the seat anchoring member 57 may include a seat top hook 61 having an angular configuration. Although the seat top hook 61 illustrated in the figures has a generally J-shaped configuration, it should be understood that seat top hooks 61 having any configuration including a distal end 63 that can be received within the gap defined between the distal end 59 of the base top hook 58 and the base body 22 are contemplated herein (see Figure 51 and 52 ).

[0225] Alternatively or additionally, a portion of the base body 22, such as the rear portion 26, may include a base anchoring member 56 configured to connect to a corresponding seat anchoring member (57) of a child seat. In the illustrated non-limiting embodiment, the base anchoring member 56 may be fixedly mounted to the base body 22. The seat anchoring member 57 associated with the child seat may be fixed or movable about the child seat to accommodate connection with the base anchoring member 56 when the child seat is in a plurality of positions, such as a first reclined position and a second reclined position, as will be described in more detail below. Alternatively, the base anchoring member 56 may be movable about the base body 22, and the seat anchoring member 57 may be fixedly mounted to the child seat. The configuration of the seat anchoring member 57 and the base anchoring member 56 allows the connection between the seat anchoring member 57 and the base anchoring member 56 to move relative to either the child seat or the base body 22 as the child seat transitions between the first reclined position and the second reclined position, as will be described in more detail below.

[0226] Alternatively or additionally, the seat anchoring member 57 may be designed with a self-centering feature to facilitate alignment or connection with the base anchoring member 56, regardless of the position of the seat anchoring member 57 along its movement path relative to the child seat. In an embodiment, the self-centering feature includes an angled contact surface configured to engage the base anchoring member 56 to center its attachment point relative to the base anchoring member 56. As will be described in more detail below, the base anchoring member 56 is generally disengaged from the corresponding seat anchoring member 57 before the child seat 10 attached to the seat receiving assembly 40 rotates about an axis relative to the support base 20.

[0227] The support base 20 may additionally include a tether assembly for securing the support base 20 to the vehicle seat 2. The tether assembly includes a tether support 65 movable relative to the base body 22 between a first position and a second position. In an embodiment, the tether support 65 is located at or integrally formed with the tilt member 42 (such as its upper end). Thus, the tether support 65 may move relative to the base body 22 together with the tilt member 42, as will be described in more detail below. The tether support 65 may be formed of any suitable material and has a U-shape in the illustrated non-limiting embodiment, with the ends of the tether support 65 connected to the base top hook 58 or directly to a portion of the tilt member 42. A tether strap (not shown) is connected to the support base 20 and extends through an opening 67 formed in the upper surface of the base body 22 or the base anchoring member 56 and may be connected to a portion of the vehicle seat 2. When the tether strap extends through the opening 67 and is connected to the vehicle seat, the tether strap abuts the tether support 65 such that at least a portion of the load acting on the tether strap is transferred to the tether support 65 rather than the base body 22.

[0228] Continuing referenceFigure 2 and 3 and additionally refer to Figures 6 - 7 , the seat storage assembly 40 additionally includes a seat attachment 60. In the illustrated non - limiting embodiment, the seat attachment 60 includes a support platform 62 and an attachment member 64. The support platform 62 can be positioned in an overlapping arrangement with the attachment member 64. The support platform 62 can include two guide rails 66, which are adapted to receive and couple to corresponding portions of the child seats 10a, 10b to lock the child seats to the seat attachment 60. As shown, the guide rails 66 can be symmetric and substantially identical. In the illustrated non - limiting embodiment, each guide rail 66 includes a first groove 68 and a second groove 70 spaced from the first groove 68. The first groove 68 and the second groove 70 can be formed as recesses in the upper surface of the guide rail 66 and sized to receive and hold a portion of the components disposed at the bottom or base portion of the child seats 10a, 10b, such as shafts 14, 16( Figure 2 ). Although not shown, it should be understood that each of the first groove 68 and the second groove 70 can include a snap, and a corresponding latch (not shown) can engage with the snap to lock the child seats 10a, 10b to the seat attachment 60.

[0229] As Figure 2 , 3 and best shown in 6, a ring or circular collar 72 can project from the bottom of the support platform 62. Additionally, one or more flanges 74 can extend radially outward from the distal end of the collar 72. The flanges 74 may or may not extend around the entire periphery of the collar 72. In such embodiments, the base 76 of the attachment member 64 can also include one or more radially outwardly extending flanges 78. Thus, when the support platform 62 is mounted to the attachment member 64 in an axially overlapping configuration as shown, at least one flange 78 of the attachment member 64 is disposed in the plane of one or more flanges 74 of the collar 72. Additionally, the flanges 74, 78 can cooperate to form a flange that extends around the entire periphery of the collar 72.

[0230] The seat storage assembly 40 can additionally include a support plate 80 for mounting the seat attachment 60 to the base body 22. As shown, the support plate 80 has a central opening 82 formed therein. Both the collar 72 of the support platform 62 and the base 76 of the attachment member 64 extend through the opening 82 such that the flanges 74, 78 are adjacent to the bottom side of the support plate 80. This engagement between the flanges 74, 78 and the support plate 80 can prevent the seat attachment 60 from separating from the support plate 80.

[0231] As Figure 4Best shown in, the base body 22 has an opening 84 formed in the upper surface of the seat portion 24. The support plate 80 can be mounted to the base body 22 adjacent to or overlapping with the opening 84 (see FIG. 1). For example, in an embodiment, a portion of the support plate 80, such as its first end 86, can be received inside the interior 44 of the base body 22. In the illustrated non-limiting embodiment, fins 88 (see Figure 3 ) protruding from the support plate 80 near its first end 86 are configured to abut against an adjacent surface of the base body 22, such as the inner surface of the seat portion 24, to restrict movement of the support plate 80 relative to the base body 22. In such embodiments, the profile of the fins 88 can be complementary to the profile 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 connected to the base body 22 in another suitable manner are also within the scope of the present disclosure.

[0232] When the support plate 80 is mounted around the base body 22, the support plate 80 generally seals the opening 84 of the seat portion 24. In addition, the upper surface of the support platform 62 including the guide rail 66 for connecting to a child seat is vertically disposed above the support plate 80 at the outside of the base body 22.

[0233] In an embodiment, the seat attachment 60 is movably coupled to the support base 20, such as coupled to the tilt member 42. For example, the seat attachment 60 can be rotatably coupled to the tilt member 42. Thus, the seat attachment 60 can rotate between a first rotational configuration and a second rotational configuration relative to the tilt member 42, the support plate 80, and the base body 22, the first rotational configuration being, for example, a configuration in which a child seat coupled to the seat receiving assembly 40 is in a forward position ( Figure 13A ), the second rotational configuration being, for example, a configuration in which a child seat coupled to the seat receiving assembly 40 is in a rearward position ( Figure 13B ) or one or more other configurations ( Figure 14B ).

[0234] Referring to Figure 5 、 7 and 8, in the illustrated non-limiting embodiment, the tilt member 42 includes a mounting bracket 90 coupled to a lower portion 50 of one or both of the first leg 46a and the second leg 46b. A mounting post 92 projects from the upper surface 94 of the mounting bracket 90. The attachment member 64 can similarly include a plate 96 having an opening 98 formed therein, and the mounting post 92 can be received within the opening 98 to define the axis of rotation X of the seat attachment 60. Thus, the coupled support platform 62 and the attachment member 64 can rotate together about the axis X relative to the tilt member 42, the support plate 80, and the base body 22.

[0235] In an embodiment, the allowable rotation of the seat attachment 60 about the axis of rotation X is changed based on the child seat connected thereto. For example, when a first child seat, such as the 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 configuration ( Figure 13A ) and a second rearward configuration ( Figure 13B ). The first and second rotational configurations of the first child seat 10a can be arranged 180 degrees apart. When a second child seat, such as the 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 configuration ( Figure 14B ) and a second lateral configuration ( Figure 14B and 16B ). The first and second rotational configurations associated with the second child seat 10b can be arranged approximately 90 degrees apart, or any amount less than 180 degrees. Thus, the allowable rotation of the seat attachment 60 when the first child seat 10a is connected to the seat attachment 60 is greater than the allowable rotation of the seat attachment 60 when the second child seat 10b is connected to the seat attachment 60. However, embodiments are also contemplated herein where the seat attachment 60 can rotate in the same manner when both the first child seat 10a and the second child seat 10b are attached thereto.

[0236] As previously noted, a child seat, such as the first child seat 10a, can have a seat anchoring member 57 mounted to its rear portion. Thus, in the case where the child seat is in the first rotational configuration, the seat anchoring member can be connected to the base anchoring member 56. When the child seat rotates relative to the base about the axis to the second rotational configuration, the seat anchoring member is spaced apart from the base anchoring member 56. Further, when the child seat rotates from the second rotational configuration to the first rotational configuration, the seat anchoring member 57 can be configured to automatically align with the base anchoring member.

[0237] 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 the first and second rotational configurations. When the spin lock mechanism is engaged, the rotation of the seat attachment 60 about the axis of rotation X is restricted. It should be understood that the spin lock mechanism can be operable to lock the seat attachment 60, and thus the child seat coupled thereto, in only the first and second configurations, or alternatively, at any suitable position along the rotational path between the first and second rotational configurations.

[0238] The spin release actuator 100 can be operable to selectively disengage the spin lock mechanism and thus allow rotation of the seat attachment 60 about the axis X. In an embodiment, at least a portion of the spin release actuator 100 is located at a child seat that can be connected to the seat attachment 60 (see Figures 13A - 13B ). However, embodiments are also covered herein where all or at least a portion of the spin release actuator 100 is locally mounted around the support base 20.

[0239] Now referring to Figures 23 - 27 , another example of the seat storage assembly 40 and the seat attachment 60 will be described. The seat attachment 60 similarly includes a support platform 200 that can be positioned in an overlapping arrangement with the attachment member 202, as previously described. The support platform 200 can include one or more guide rails 204 that are adapted to receive and couple to corresponding portions of the child seats 10a, 10b to lock the child seats 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 that are spaced apart from each other. The first groove 206 and the second groove 208 can be formed as recesses in the upper surface of the guide rail 204 and are sized to receive and hold a portion of the child seat, such as the shafts 14, 16. The first groove 206 and the second groove 208 can include latches, and corresponding latches (not shown) can engage with the latches to lock the child seats 10a, 10b to the seat attachment 60.

[0240] As best shown in Figure 27 , similar to the previous embodiment, an annular or circular collar 210 extends downward from the bottom 212 of the support platform 200. In an embodiment, one or more openings 214 are formed in the collar 210. The attachment member 202 can include one or more radially outwardly extending legs 216 and each leg can be received within a corresponding opening 214 in the collar 210 to couple the support platform 200 to the attachment member 202. In an embodiment, the attachment member 202 includes a collar 217 from which the legs 216 project outwardly. The collar 217 has one or more openings 219 formed therein such that when the support platform 200 is coupled to the attachment member 202, the collar 217 is received within the opening 214 and the collar 210 is received within the opening 219. Thus, the support platform 200 and the attachment member 202 can jointly define a collar that extends around the entire periphery of the seat attachment 60.

[0241] In an embodiment, the bottom of at least one radially outwardly extending leg 216 is arranged to be generally flush with a corresponding bottom surface of the collar 210. However, embodiments are also contemplated herein where the legs 216 are not flush with the bottom surface of the collar 210. Additionally, both the collar 210 of the support platform 200 and the legs 216 of the attachment member 202 may extend through an opening 82 formed in a support plate, such as support plate 80.

[0242] Similar to the previous embodiments, the seat attachment 60 is movably coupled to the support base 20, such as via the tilt member 42. The seat attachment 60 may rotate relative to the support base 20 about an axis X between a plurality of rotational configurations including a first rotational configuration and a second rotational configuration. Continuing reference Figure 28 、 29A and FIGS. 29B, illustrate an example of a locking mechanism 220 operable to selectively restrict movement of the seat attachment 60 about its axis. Although the locking mechanism 220 is described and illustrated herein with respect to the seat attachment of FIGS. 25 - 29B, it should be understood that the locking mechanism 220 may be adapted to be used with Figure 2 、 3 、6 and 7's seat attachment 60 or another suitable seat attachment.

[0243] As shown, the locking mechanism 220 may include a locking member 222 that is movable along an axis generally perpendicular to the axis of rotation of the seat attachment 60 between a disengaged position and an engaged position, such as translatable along the axis between the disengaged position and the engaged position. When the locking member 222 is in the engaged position, the spin locking mechanism prevents rotation of the seat attachment 60. At least one opening 224 ( Figure 28 ) may be formed in the annular collar 210 of the support platform 200. In the illustrated non - limiting embodiment, a first opening 224 is formed in the annular collar 210 of the support platform 200 at a first position associated with the first rotational configuration, such as a forward position, and a second opening (not shown) is formed in the annular collar 210 at a second or another position associated with the second rotational configuration, such as a fore - aft position. The size and shape of the opening 224 are selected such that at least a portion of the locking member 222 can be received therein. In some embodiments, one or more of the openings are generally the same in size and / or shape as the portion of the locking member 222 that can be received therein.

[0244] In the engaged position, at Figure 28In the best display, at least a portion of the locking member 222 extends into an opening 224 formed in the annular collar 210. In this configuration, a portion of the seat attachment 60, such as the engagement between the sidewall of the opening 224 and the locking member 222, restricts the rotation of the support platform 200 and thus the child seat attached thereto about its axis X. Although not shown, a biasing mechanism may be operatively coupled to the locking member 222. In such embodiments, the biasing force of the biasing mechanism may be configured to bias the locking member 222 toward the engaged position.

[0245] One or more actuators may be operable to transform the locking member 222 to the disengaged position, such as by resisting the bias of the biasing mechanism, thereby allowing the seat attachment 60 to rotate about its axis of rotation X. In an 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 additionally, 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.

[0246] Now refer to Figures 30A - 30B , and describe the locking mechanism 220 according to another embodiment. As shown, the locking member 222 is mounted to the base body 22 and is rotatable about an axis between an engaged or locked position ( Figure 30A ) and a disengaged or unlocked position ( Figure 30B ). As Figure 31 best shows, a stationary component, such as a portion of the spin locking mechanism 240 that defines the rotational path of the seat attachment (which will be described in more detail below), may be located within the support base 20. In the illustrated non-limiting embodiment, the spin locking 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 grooves, recesses, or pawls. When the locking member 222 is in the locked position, a portion of the locking member may be received within the corresponding locking feature 247. The engagement between the locking member 222 and the locking feature 247 restricts the rotation of the seat attachment 60 about the axis X in any direction. When the locking member 222 is in the disengaged position, the locking member 222 rotates about its axis and disengages from the locking feature 247. Thus, the seat attachment 60 is free to rotate relative to the support base 20 to the desired position.

[0247] The rotational locking actuator 230 can be operable to transform the locking member 222 to the disengaged position. In the illustrated non-limiting embodiment, the operation of the rotational locking actuator 230 directly applies a force to a portion of the locking member 222, causing the locking member 222 to rotate about its axis. The operation of the rotational locking actuator 230 additionally resists the biasing of a biasing mechanism 231 that is operably coupled to the rotational locking actuator. After the actuator is released, the biasing mechanism 231 will bias the rotational locking actuator 230 to disengage from the locking member 222. Additionally, the overall shape and body of the locking member 222 can be selected such that when the force from the rotational locking actuator is removed, the force of gravity acting on the locking member 222 will cause the locking member to pivot about the axis toward the engaged position. It should be understood that the various configurations of the locking mechanism 220 illustrated and described herein are intended only as examples, and a locking mechanism 220 having any suitable configuration that is operable to selectively restrict rotation of the seat attachment is within the scope of the present disclosure.

[0248] At least one of the actuators 230, 232 includes an actuator mechanism 233 that can be accessed by a user to operate the actuator. In Figures 23 - 24B the illustrated non-limiting embodiments of, 27, 30A - 30B, and 32B, the actuator mechanism 233 is disposed at the seat attachment 60 and is movable relative to the support base 20 about the rotational axis X together with the seat attachment. Thus, when the infant car seat 10b is connected to the seat attachment 60, the user applies a force to the rotational locking actuator 230 via the actuator mechanism 233 to rotate the seat attachment 60 as needed. In embodiments where the toddler seat 10a is connected to the seat attachment, the toddler seat 10a can cover the actuator mechanism 233. In such embodiments, a spin actuator 251 integral with the toddler seat 10a can be operably coupled (e.g., via an actuator member 235) to the actuator mechanism 233 or another portion of the actuator 230 such that operation of the spin actuator 251 located on the toddler seat 10a will transform the locking member 222 from the locked position to the unlocked position.

[0249] In embodiments that include multiple actuators 230, 232, the actuator mechanism of each actuator can be disposed at various locations. For example, the actuator mechanism of a first actuator 230 associated with the locking mechanism 220 can be mounted to the support base 20 and the actuator mechanism of a second actuator 232 associated with the locking mechanism 220 can be located at the child seat 10a, 10b connected to the seat attachment 60. In Figure 28 the non-limiting embodiment shown in, the actuator mechanism of an actuator, such as the second actuator 232, can be disposed along the vehicle seat belt path for directly attaching the child seat 10a to the vehicle seat 2 in the absence of the support base 20 at the child seat 10a.

[0250] Reference Figure 5 、 7 and 8, in the illustrative non - limiting embodiments, the recline 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 the upper surface 94 of the mounting bracket 90. The attachment member 64 may similarly include a plate 96 having an opening 98 formed therein, and the mounting post 92 may be received within the opening 98 to define the axis of rotation X of the seat attachment 60. Thus, the coupled support platform 62 and attachment member 64 may jointly rotate about the axis X relative to the recline member 42, the support plate 80, and the base body 22.

[0251] In an embodiment, the allowable rotation of the seat attachment 60 about the axis of rotation X varies based on the child seat connected thereto. For example, when a first child seat, such as the convertible child seat 10a, is coupled to the seat attachment 60, the first child seat 10a may rotate about the axis X between a first forward configuration ( Figure 13A ) and a second rearward configuration ( Figure 13B ). The first and second rotational configurations of the first child seat 10a may be arranged 180 degrees apart. When a second child seat, such as the infant child seat 10b, is attached to the seat attachment 60, the second child seat 10b may rotate about the axis of rotation X between a first rearward configuration ( Figure 14B ) and a second lateral configuration ( Figure 14B and 16B ). The first and second rotational configurations associated with the second child seat 10b may be arranged approximately 90 degrees apart, or any amount less than 180 degrees. Thus, the allowable rotation of the seat attachment 60 when the first child seat 10a is connected to the seat attachment 60 is greater than the allowable rotation of the seat attachment 60 when the second child seat 10b is connected to the seat attachment 60. However, embodiments are also contemplated herein where the seat attachment 60 rotates in the same manner when both the first child seat 10a and the second child seat 10b are attached thereto.

[0252] As previously noted, a child seat, such as the first child seat 10a, may have a seat anchor member 57 mounted to its rear portion. Thus, in the case where the child seat is in the first rotational configuration, the seat anchor member may be connected to the base anchor member 56 or 58. When the child seat rotates relative to the base about the axis to the second rotational configuration, the seat anchor member is spaced apart from the base anchor members 56, 58. Further, when the child seat rotates from the second rotational configuration to the first rotational configuration, the seat anchor member 57 may be configured to automatically align with the base anchor member.

[0253] Referring again to Figures 28 - 29B and additionally referring toFigures 33A - 33C , an example of a spin lock mechanism 240 for defining and / or controlling the rotation of the seat attachment 60 about the axis X is described. The spin lock mechanism 240 can be used to control the allowable rotation of the seat attachment relative to the support base 20 based on the type of child seat 10a, 10b attached to the seat attachment 60. As shown, the spin lock mechanism 240 can include a spin bracket assembly 242, a first spin lock member 244, and a second spin lock member 246. The first spin lock member 244 is fixedly mounted relative to the support base 20. In an embodiment, the first spin lock member 244 is integrally formed with or fixedly mounted to the mounting bracket 90. The spin bracket assembly 242 and the second spin lock member 246 can rotate together with the seat attachment 60. In the illustrated non-limiting embodiment, the spin bracket assembly 242 is integrally formed with the bottom side of the support platform 200. Thus, in some embodiments, the annular collar 210 of the support platform 200 can be considered the spin bracket assembly 242. The second spin lock member 246 can be movably coupled to a portion of the seat attachment 60, such as to the spin bracket assembly 242. Thus, the spin bracket assembly 242 and the second spin lock member 246 can rotate relative to the first spin lock member 244 together with the child seats 10a, 10b attached to the seat attachment 60.

[0254] As shown, the first spin lock member 244 can have a partially circular perimeter. For example, the first spin lock member 244 can have a constant radius of at least about 200 degrees and in some embodiments at least about 220 degrees, at least 240 degrees, at least 250 degrees, at least 260 degrees, and at least 270 degrees. The remaining portion of the perimeter of the first spin lock member 244 has a reduced radius. In an embodiment, a chord portion 248 extends between two endpoints of the circular perimeter having the constant radius, and a protrusion 250 extends radially outward from the chord portion 248, such as from a central position of the chord portion 248. However, the radius at the protrusion 250 is less than the constant radius. In an 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 perimeter toward the protrusion 250.

[0255] When the spin bracket assembly 242 and the second spin lock member 246 rotate about the axis of rotation X together with the seat attachment 60, the second spin lock member 246 substantially engages with the periphery of the first spin lock member 244. In an embodiment where the first child seat 10a, such as a convertible child seat or an infant seat, is connected to the seat attachment 60, the spin bracket assembly 242 and the second spin lock member 246 can be freely configured and arranged. In the freely configured state, the spin bracket assembly 242 and the second spin lock member 246 can freely rotate 360 degrees around the entire periphery of the first spin lock member 244. In an embodiment where the second child seat 10b, such as an infant child seat, is coupled to the seat attachment, the second spin lock member 246 can be considered to be arranged in a lockable configuration. During the rotation of the spin bracket assembly 242 and the second spin lock member 246 in the lockable configuration, the engaging member 252 is configured to be adjacent to the side surface 256 of the protrusion 250. Therefore, the interference between the engaging member 252 and the side surface 256 of the protrusion 250 limits the rotation of the second spin lock member 246 to less than 360 degrees. In an embodiment, the contact between the engaging member 252 and the side surface 256 of the protrusion 250 limits the rotation of the seat attachment 60 to the forward position.

[0256] In the illustrated non - limiting embodiment, the engaging member 252 of the second spin lock member 246 is fixedly mounted to the shaft 260. The shaft 260 can rotate about its longitudinal axis between a locked position and an unlocked position. A biasing mechanism 262, such as a helical spring, can be fixedly mounted to the engaging member 252 or another part 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 towards the locked position.

[0257] When the engaging member 252 of the second spin lock member 246 is arranged to contact the circular periphery of the first spin lock member 244 having a constant radius, regardless of whether the first child seat 10a or the second child seat 10b is connected to the seat attachment 60, the contact between the engaging member 252 of the second spin lock member 246 and the first spin lock member 244 resists the biasing force of the biasing mechanism 262. Therefore, when the engaging member 252 of the second spin lock member 246 contacts the circular periphery of the first spin lock member 244 having a constant radius, the shaft 260 remains in the unlocked position.

[0258] When the second spin lock member 246 is further rotated relative to the first spin lock member 244 about the axis X, the engagement member 252 contacts the periphery of the chord portion 248 in a direction toward the protrusion 250. Since the radius at the chord portion 248 gradually decreases from its end toward the protrusion 250, the force acting on the engagement member 252 by the first spin lock member 244 and resisting the biasing force of the biasing mechanism 262 decreases. Therefore, the biasing force of the biasing mechanism 262 will cause the shaft 260 and the engagement member 252 coupled thereto to rotate about the axis to maintain the contact between the engagement member 252 and the first spin lock member 244.

[0259] When the first child seat 10a is connected to the seat attachment 60, the first child seat 10a can be configured to resist the biasing force of the biasing mechanism 262, thereby preventing the second spin lock member 246 from transitioning from the free configuration to the lockable configuration. As shown, the engagement member 252 is located radially outside the protrusion 250 in the free configuration. Due to this positioning, the second spin lock member 246 can freely rotate around the entire periphery of the first spin lock member 244.

[0260] In an embodiment, at least one removal lock member 264 is attached, for example, outside the spin bracket assembly 242 to the shaft 260 of the second spin lock member 246. Accordingly, the at least one removal lock member 264 is configured to rotate with the shaft 260 and the engagement member 252 about the axis between a locked position and an unlocked position. The first child seat 10a can include not only the shafts 14 and 16 disposed at its bottom as previously described, but also, for example, an additional intermediate shaft 17 positioned between the shafts 14, 16. In such embodiments, corresponding openings 265 (see Figure 27 ) can be formed in the seat attachment 60 for receiving the intermediate shaft 17.

[0261] When the first child seat 10a is coupled to the seat attachment 60, the intermediate shaft 17 of the first child seat 10a is disposed within the rotational path of at least one removal lock member 264 of the second spin lock member 246. Accordingly, when the engagement member 252 rotates from the end of the chord portion 248 toward the protrusion 250, the engagement between the intermediate shaft 17 and at least one removal lock member 264 coupled to the shaft 260 resists the biasing force of the biasing mechanism 262. This engagement restricts further rotation of the shaft 260, thereby preventing the second spin lock member 246 from transitioning from the free configuration to the lockable configuration.

[0262] The second child seat 10b does not include a corresponding intermediate shaft. Thus, when the second child seat 10b is connected to the seat attachment 60, the shaft 260 of the second spin lock member 246 is biased to a lockable configuration by the biasing force of the biasing mechanism 262 when the engagement member 252 rotates from the end point of the chord bar portion 248 toward the projection 250. In the lockable configuration, the engagement member 252 is biased inwardly toward the surface of the first spin lock member 244. In this first lockable configuration, the projection 250 of the first spin lock member 244 is disposed within the rotational path of the engagement member 252 of the second spin lock member 246, thereby restricting the rotation of the second spin lock member 246, the spin bracket assembly 242, and the seat attachment 60 (including the second child seat 10b) to one or more positions, such as the forward position. It should be understood that the spin lock mechanism 240 illustrated and described herein is intended only as an example and is within the scope of the present disclosure for any suitable mechanism for controlling the rotation of the seat attachment about an axis based on a child seat attached to the seat attachment 60.

[0263] In an embodiment, the separation of the first child seat 10a from the seat attachment 60 is restricted based on the position of the first child seat 10a relative to the support base 20. For example, when the first child seat 10a is disposed at any position relative to the support base 20 other than a specific position, such as when in the forward configuration, the first child seat 10a can be separated from the seat attachment. In the forward configuration, the separation of the first child seat 10a from the seat attachment 60 can be prevented by at least one removal lock member 264. As previously described, in the forward configuration, the base anchor member 56 of the first child seat 10a is connected to the corresponding seat anchor member 57 of the support base 20. Thus, the separation of the first child seat 10a from the support base 20 when coupled to the support base 20 in the forward configuration is prevented by locking at least one removal lock member 264 to the intermediate shaft 17 of the first child seat 10a.

[0264] In an embodiment, at least one removal lock member 264 is operable to selectively restrict the separation of the first child seat 10a from the seat attachment 60. The second spin lock member 246 is capable of freely rotating about the first spin lock member 244 when coupled thereto. During this rotation, as previously described, the engagement member 252 is disposed radially outside the projection 250 of the first spin lock member 244 or is configured to contact the radially outer peripheral surface 254 of the projection. As Figure 33ABest shown in, when the first child seat 10a is disposed at any position other than a specific position where separation is restricted, the shaft 260 and thus at least one removal locking member 264 are in the unlocked position. In an embodiment, when the engaging member 252 of the spin carriage assembly 242 and the second spin locking member 246 rotates towards the chord portion 248 of the first spin locking member 244, the biasing force of the biasing mechanism 262 causes at least one removal locking member 264 to rotate at least partially from the unlocked position towards the locked position. This rotation of at least one removal locking member 264 can be caused by a reduced radius of the first spin locking member 244 and a resulting contact separation between the engaging member 252 and the first spin locking member 244.

[0265] In the illustrated non-limiting embodiment, at least one removal locking member 264 includes a hook or other engaging feature 266 disposed at its distal end. When at least one removal locking member 264 rotates towards the locked position, for example due to a reduced radius of the chord portion 248 of the first spin locking member 244, the hook 266 engages with the intermediate shaft 17 or a corresponding portion associated with the intermediate shaft 17 of the first child seat 10a (best shown in Figure 33B ). Due to this engagement, when the engaging member 252 of the second spin locking member 246 rotates to the chord portion 248 of the first spin locking member 244, for example when the first child seat 10a is in the forward position, the first child seat 10a cannot be separated from the seat attachment 60. Similarly, when the first child seat 10a connected to the seat attachment 60 rotates away from the forward position, once the engaging feature 266 disengages or separates from the first child seat 10a, the first child seat 10a can be considered to be in the second rotational configuration. Although at least one removal locking member 264 is illustrated and described herein as being operable to prevent the first child seat 10a from separating from the seat attachment 60 when in the forward position, it should be understood that the seat attachment 60 can be designed to prevent the first child seat 10a from separating from it at alternative or additional positions relative to the support base 20.

[0266] Referring again to Figures 1A - 5, in an embodiment, the tilt member 42 may move (e.g., translate) relative to the base body 22 between a first position (e.g., a reclined position) and a second position (e.g., a tilted position). However, it should be understood that both the first position and the second position may be positions of a tilted arrangement, with different degrees of tilt. In the illustrated non-limiting embodiment, when in the first position, the connecting member 54 of the tilt member 42 is arranged to be generally adjacent to or flush with the upper end 101 of the rear portion 26 of the base body 22. Similarly, when in the second position, the tilt member 42 projects through an opening 103 formed at the upper end 101 of the rear portion 26 such that the connecting member 54 is spaced a distance from the end of the rear portion 26.

[0267] Reference Figure 9 and 10 , in the illustrated non-limiting embodiment, the tilt member 42 includes a frame having one or more legs 46. As shown, at least one of the first leg 46a and the second leg 46b of the tilt member 42 has one or more pins 102 projecting outward therefrom. Although two pins 102 ( Figure 10 ) are shown as projecting from each leg 46a, 46b (central portion and one end), it should be understood that embodiments having only a single pin or more than two pins are also within the scope of the present disclosure. Further, although each of the pins 102 is shown as being disposed at the lower portion 50 of each leg 46a, 46b 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 legs 46a, 46b.

[0268] For example, referring to Figure 38 the embodiment of the tilt member 42 illustrated therein, the tilt member 42 is slidably connected to the support base 20 at a plurality of different positions. A first sliding pin connection may be disposed near the upper end of the rear portion 26 of the support base 20 and a second sliding pin connection may be disposed near the central portion of the support base 20, e.g., near the interface between the seat portion 24 and the rear portion 26 of the base body 22. In an embodiment, a roller 111 may be mounted at or near one end of the tilt member 42 near the stability leg 32. In such embodiments, the roller 111 may be configured to roll along or engage a ramp or track portion located at an adjacent surface of the base body 22.

[0269] A plurality of mobile brackets 104 are arranged within the interior 44 of the base body 22, for example adjacent to the surface of at least one of the legs 46a, 46b. The mobile brackets 104 may be fixed to the base body 22. Although the brackets 104 are illustrated as separate components positioned within the interior 44 of the base body 22, it should be understood that embodiments in which the mobile brackets 104 are integrally formed with the base body 22 are also contemplated herein. The mobile brackets 104 may have at least one elongated slot 106 formed therein, and the corresponding pins 102 of the tilt member 42 may be received within each slot 106. The position of the pins 102 within the slots 106 allows the force applied to the base body 22 by the vehicle seat belt 12 to be directly transmitted to the tilt member 42. The slots 106 define the movement path of the tilt member 42 relative to the base body 22. Thus, in the illustrated non-limiting embodiment, the tilt member 42 is in a first or reclined position when the pins 102 are positioned adjacent the first end 108 of each of the slots 106, and the tilt member 42 is in a second or tilted position when the pins 102 are positioned adjacent the second opposite end 110 of each of the slots 106.

[0270] It should be understood that the pin and slot engagement described herein is presented only as an example and any configuration that allows movement of the seat receiving assembly 40 relative to the base body 22 is within the scope of the present disclosure. For example, in an embodiment, the legs 46a, 46b of the tilt 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.

[0271] Referring Figures 11A - 12B , alternative or additional connections between the seat receiving assembly 40 and the base body 22 are illustrated. As shown, at least one rib 83, such as a plurality of ribs, projects upwardly from the upper surface of the fin 88 of the support plate 80. The rib 83 may or may not extend beyond the end 85 of the support plate 80. Additionally, the configuration of the rib 83 may be generally the same or may vary. In the illustrated non-limiting embodiment, the plurality of ribs 83 are spaced apart from each other to define slots 87 between adjacent ribs 83. As Figure 11BIn the best display, the inner surface 89 of the base body 22 facing the fin 88 includes one or more protrusions 91 that can be slidably received within one or more slots 87 defined by ribs 83. In embodiments including multiple protrusions 91, the protrusions 91 may be generally the same or may vary. Additionally, the protrusions 91 may be axially spaced above the inner surface 89 in one or more directions such that two or more protrusions 91 can be received within the same slot 87. However, in other embodiments, both the upper surface of the fin 88 and the corresponding inner surface 89 of the base body 22 may be generally smooth. In such embodiments, the upper surface of the fin 88 may be separated from the inner surface 89 of the base body 22 by a certain interval or gap such that the support plate 80 can move freely relative to the base body 22 together with the tilting member 42.

[0272] Reference Figure 12A and 12B , when the tilting member 42 and thus the support plate 80 and the seat attachment 60 translate between a first position ( Figure 12A ) and a second position ( Figure 12B ), at least one protrusion 91 remains disposed within the corresponding slot 87, thereby restricting lateral movement of the seat storage assembly 40. Additionally, this engagement between at least one slot 87 and the protrusion 91 allows vehicle seat belt forces to be transmitted directly through the base body 22 to the seat storage assembly 40.

[0273] Furthermore, it should be understood that since 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 relative to the support base 20 together with the tilting member 42.

[0274] The tilting member 42 can be in a first position ( Figure 13A , 13B , 14A and 14B) and a second position ( Figure 15A , 15B、between 16A and 16B), regardless of the rotational position of the seat attachment 60 relative to the base body 22 and the reclining member 42. For example, when the seat attachment 60 is in any position of a 360-degree rotation of the seat attachment 60, the reclining member 42 may be movable. Similarly, the seat attachment 60 may rotate about the axis X, regardless of the position of the reclining member 42 relative to the base body 22. As shown, the child seats 10a, 10b may recline when both are in the first forward configuration, the second rearward configuration, and any position therebetween. Additionally, since the reclining member 42 is located within the interior 44 of the base body 22 and is separated from the seat belt pretensioner 35 and the seat belt storage path, the reclining member 42 may move between the first position and the second position without affecting the position of the vehicle seat belt on the seat belt storage path and without affecting the tension applied to the vehicle seat belt by the seat belt pretensioner 35.

[0275] In Figure 9 In the illustrated non-limiting embodiment best shown in Figure 9 , the reclining member 42 includes a plurality of recline retaining members 112, such as being vertically overlapped with the lower portions 50 of the legs 46a, 46b, respectively. The end 114 of the recline retaining member 112 closest to the mounting bracket 90 may have a profile complementary to the periphery of the collar 72 or the flanges 74, 78. Although each recline retaining member 112 is illustrated as a distinct component, embodiments in which each of its ends 114 cooperate or couple to define a ring extending substantially around the entire periphery of the collar or flanges 74, 78 are also within the scope of the present disclosure.

[0276] When the reclining member 42 is transformed from the first or reclined position to the second or tilted position, the end 114 of the recline retaining member 112 disposed on the first side of the collar 72 is configured to engage a portion of the flange 74, 78 of the seat attachment 60 to prevent lateral movement of the seat attachment 60. Similarly, when the reclining member 42 is transformed from the tilted position to the reclined position, the end 114 of the recline retaining member 112 disposed on the second side of the collar 72 is configured to engage a portion of the flange 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 arranged in either the forward configuration or the rearward configuration, the recline retaining member 112 is configured to engage at least one flange 78 of the attachment member 64 to limit unwanted movement of the seat attachment 60. However, embodiments in which one or more of the recline retaining members 112 are alternatively or additionally configured to engage the flange 74 of the collar 72 when the seat attachment 60 is in either the forward configuration or the rearward configuration are also covered herein. It should also be understood that the recline retaining member 112 may be configured to contact one or both flanges 74, 78 based on the relative position of the seat attachment 60.

[0277] In addition, because the opening 82 of the support plate 80 is generally the same size as the diameter of the collar 72, in some embodiments, movement of the seat attachment 60 resulting from movement of the tilt 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 a size greater than the opening 84 formed in the base body 22, the opening 84 remains covered regardless of the position of the support plate 80.

[0278] 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 tilted configuration. When engaged with the tilt locking mechanism, movement of the tilt member 42 relative to the support base 20 is restricted. It should be understood that the tilt locking mechanism can be operable to lock the tilt member 42 in only one of the reclined position and the tilted position. However, in other embodiments, the tilt locking mechanism can be configured to lock the tilt member 42 at any suitable position along the movement path between the reclined position and the tilted position to achieve different degrees of tilt of the seat attachment 60.

[0279] Now referring Figures 35 - 37 , an example of the tilt locking mechanism 300 will be described. As shown, the tilt locking 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 recline member 306 operatively coupled to the locking pin 304. The housing of the tilt locking mechanism can be attached to a portion of the moving bracket 104, such as at a position offset from the slot 106. The recline member 306 includes a post or pin that is disposed within an elongate slot 308 formed in the housing 302. In the illustrated non-limiting embodiment, the slot 308 is arranged at an angle to the movement path of the locking pin 304.

[0280] As shown, the locking bracket 310 can be disposed between the mounting bracket 104 and the surface of the leg 46a of the tilt member 42. Thus, the pin 102 can be formed as part of the locking bracket 310 or alternatively can also 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 tilted position. The plurality of locking openings 312 can additionally include one or more openings disposed between the first and second locking openings associated with at least one intermediate position of the tilt member 42.

[0281] The tilt locking mechanism 300 is positioned such that the locking pin 304 is generally aligned or disposed within the plane containing the plurality of locking openings 312. Receiving the locking pin 304 within one of the plurality of locking openings 312 restricts movement of the locking bracket 310 and thus the tilt member 42 relative to the mounting bracket 104 and the base body 22. As the pin 102 translates within the slot 106, the locking bracket 310 moves relative to the tilt locking mechanism 300 such that different locking openings of the plurality of locking openings 312 are sequentially aligned with the locking pin 304 above the tilt movement path.

[0282] Reference Figure 37 , the tilt release actuator 320 is operable to selectively disengage from the tilt locking mechanism 300, thereby allowing movement of the tilt member 42 relative to the support base 20. In an embodiment, the tilt release actuator 320 is operable to disengage the locking pin 304 from one of the plurality of locking openings 312 formed in the locking bracket 310, thereby allowing movement of the locking bracket 310 coupled to the tilt member 42 relative to the mounting bracket 104. In an embodiment, the tilt release actuator 320 is operably coupled to the recline member 306 by a cable or tension member 322. In response to operation of the tilt release actuator 320, the recline member 306 is configured to translate within a slot 308 formed in the housing 302. This movement of the recline member 306 causes the locking pin 304 to translate out of the plane of the locking bracket 310, thereby separating the locking pin 304 from the corresponding locking opening 312. It should be understood that the tilt locking mechanism 300 and the tilt release actuator 320 illustrated and described herein are intended only as examples and that a locking mechanism or release actuator having another suitable configuration is within the scope of the present disclosure.

[0283] Although the input 116 associated with the operation of the tilt release actuator is illustrated as being disposed at the support plate 80, such as near the second end of the seat portion 24 of the base body 22, in other embodiments, the input may be located at another location around the support base 20. For example, in Figure 32B and 39A -39C non-limiting embodiments, the input 116 associated with the operation of the tilt release actuator 320 is located at one side of the base body 22 and is accessible when both the first child seat 10a and the second child seat 10b are coupled to the seat attachment 60.

[0284] The support base 20 as described herein provides the benefit of being suitable for use with a plurality of interchangeable child seats such that as the child grows, the same base can be used with different seats.
