[0217] A detailed description of one or more embodiments of the disclosed apparatus and method is provided herein with reference to the accompanying drawings, which are shown by way of example, and not limitation.

[0218] Referring now to the drawings, various examples of child safety seat systems 20 are shown. In each of the non-limiting embodiments shown, the child safety seat system 20 includes a support base 22 that can be removably secured to a vehicle seat 10 (see Figure 1 and 20), for example, via a latch (LATCH) system. Alternatively or additionally, the support base 22 can be removably secured to the vehicle seat 10 via a vehicle seat belt associated with the vehicle seat 10.

[0219] Child safety seat system 20 additionally includes a child safety seat 24 associated with support base 22. In one embodiment, child safety seat 24 is detachably coupled to support base 22, thereby allowing child safety seat 24 to be separated from support base 22. Alternatively, at least a portion of support base 22 and child safety seat 24 can be permanently connected or attached together, as will be described in greater detail below. As used herein, the term "permanently connected" refers to embodiments in which child safety seat 24 or a portion thereof is not intended to be detached from support base 22 by a user.

[0220] Child safety seat 24 includes a seat back portion 26 and a seat bottom portion 28 disposed at an angle relative to seat back portion 26. Seat bottom portion 28 can, but need not be, configured to be removably coupled to seat back portion 26. In the illustrated, non-limiting embodiment, seat back portion 26 includes a seat back having an upright support surface 30 that generally faces forward and extends from a first end or top 32 of seat back portion 26 to a second, opposite end or bottom 34 of seat back portion 26. A first upright side member 36 can be disposed at a first side 38 of upright support surface 30, and a second upright side member 40 can be disposed at a second, opposite side 42 of upright support surface 30. Thus, first upright side member 36 and second upright side member 40 form the left and right sides, respectively, of seat back portion 26. As shown, first upright side member 36 and second upright side member 40 extend forward from upright support surface 30. First upright side member 36 and second upright side member 40 can extend generally normal to upright support surface 30, or alternatively, can extend at another angle, such as an angle greater than 90° therefrom. Thus, upright support surface 30, as well as first upright side member 36 and second upright side member 40, define a back region or upright support cavity within which an upper body of a child is received.

[0221] Upright side members 36, 40 can facilitate proper positioning of vehicle safety belts during one or more modes of operation when child safety seat 24 is installed within a vehicle. Although not illustrated, in some embodiments, each upright side member 36, 40 has an opening formed therein. The opening can be configured to receive a vehicle safety belt (not shown) to secure child safety seat 24 to vehicle seat 10 in a forward-facing configuration or to secure an upper body of a child positioned within the cavity.

[0222] In Figures 21A to 23In the illustrated non-limiting embodiment, the seat back portion 26 is an assembly that includes a seat back 27 from which the upright support surface 30 and the first upright side member 36 and the second upright side member 40 extend at an angle as previously described. A separate back cover or seat back shell 29 can be positioned in contact with a rear-facing surface 31 of the seat back 27. In the illustrated non-limiting embodiment, the seat back shell 29 has a size and shape that is complementary to the seat back 27 such that the seat back shell 29 overlaps the entire rear-facing surface 31 of the seat back 27. However, embodiments in which the seat back shell 29 has a configuration that covers only a portion of the rear-facing surface 31 of the seat back 27 are also within the scope of the present disclosure. In such embodiments, the seat back shell 29 is formed of a first material, such as plastic or composite material, and the seat back 27 can be formed of a different second material, such as polystyrene or high-density foam. In addition, a textile (not shown) can be attached to an inner-facing surface of the seat back 27 to provide cushioning for a child seated within the back region.

[0223] With continued reference to Figures 21A to 23 In the illustrated non-limiting embodiment, the seat back panel 33 is mounted in overlapping arrangement with the upright support surface 30 of the seat back 27. The seat back panel 33 can have a configuration that is complementary to the upright support surface 30. As shown, the seat back panel 33 is generally rectangular and has a length that is approximately equal to the distance between the top 32 and the bottom 34 of the upright support surface 30 and a width that is generally equal to the distance between the first side 38 and the second side 42 of the upright support surface 30. In other embodiments, the seat back panel 33 can cover only a portion of the upright support surface 30 or, alternatively, can extend beyond the upright support surface 30, such as in overlapping arrangement with one or both of the first upright side member 36 and the second upright side member 40.

[0224] Regardless of the configuration of the seat back portion 26, in non-limiting embodiments, one or more shock absorbers or side impact pods 37 that are designed to absorb forces in the event of an accident or crash can be arranged at the outer surface 35 of the seat back portion 26. While a single impact pod 37 is shown in the illustrated non-limiting embodiment, it is contemplated that two or more impact pods 37 can be arranged at the outer surface 35 of the seat back portion 26. Figures 21A to 23embodiments having multiple impact pods 37 are within the scope of the present disclosure. As shown, the at least one impact pod 37 can be disposed proximate the top 32 of the seat back portion 26. In an embodiment, the at least one impact pod 37 can be disposed vertically positioned higher than the support base 22, for example when the child safety seat 24 is in a forward-facing configuration. Further, the at least one impact pod is disposed out of contact with the vehicle seat 10 when the child safety seat system 20 is installed about the vehicle seat 10. However, embodiments including impact pods 37 disposed alternatively or additionally in another location are also contemplated herein. In the illustrated non-limiting embodiment, the impact pod 37 is disposed generally centrally and extends or wraps around the outer surface 35 toward at least one of the first upright side member 36 and the second upright side member 40, and in some embodiments, both. Thus, the at least one impact pod 37 can substantially enclose the back of the seat back portion 26. However, it is appreciated that embodiments in which one or more impact pads 37 are positioned only at the center of the seat back portion, for example generally aligned with the upright support surface 30, or only at one side of the outer surface, for example aligned with one of the upright side members 36, 40, are also contemplated herein.

[0225] In the illustrated non-limiting embodiment, the seat back portion 26 of the child safety seat 24 includes a headrest 46. The headrest 46 can be attached to, or integral with, the seat back portion 26 or can be removably coupled therewith. The headrest 46 can be fixed, or in some embodiments, can be configured to move relative to the upright support surface 30. For example, the headrest 46 can be configured to translate relative to the upright support surface 30 between a retracted position and an extended position, allowing for adjustment based on the size of a child positioned within the child safety seat 24. However, it is appreciated that embodiments in which the seat back portion 26 does not include a headrest 46 are also contemplated herein.

[0226] Reference Figure 5 , 6And 24A to 24C, in an embodiment, the headrest 46 includes a main body, identified at 300, having a head support surface 302. A first head side member 304 can be disposed at a first side 306 of the head support surface 302, and a second head side member 308 can be disposed at a second, opposite side 310 of the head support surface 302. The first and second head side members 304, 308 form respective left and right sides of the headrest 46. The first and second head side members 304, 308 extend forwardly from the head support surface 302. Thus, the head support surface 302, as well as the first and second head side members 304, 308, define a headrest region or cavity within which a child's head positioned within the child safety seat 24 is received. The first and second head side members 304, 308 can extend generally orthogonally to the head support surface 302, or alternatively, can extend therefrom at another angle, e.g., an angle greater than 90°. The angle of at least one of the first and second head side members 304, 308 relative to the head support surface 302 can be equal to or can differ from the angle of a corresponding one of the first and second upright side members 36, 40 relative to the upright support surface 30.

[0227] In an embodiment, as shown in Figures 24A to 24C The main body of the headrest 46 is, in an embodiment, an assembly including a first portion 312 having the head support surface 302, as well as the first and second head side members 304, 308 extending angularly therefrom as described. A second portion 314 including a headrest cover or panel can be positioned in contact with a rear-facing surface (not shown) of the first portion 312. In the illustrated, non-limiting embodiment, the second portion 314 has a size and shape complementary to the first portion 312, such that the second portion 314 substantially overlaps the entire rear-facing surface of the first portion 312. In such embodiments, the second portion 314 can be a structural shell formed of a first material, e.g., plastic, and the first portion 312 can be formed of a different second material, e.g., polystyrene or high-density foam. A textile (not shown) can be disposed at one or more surfaces of the first portion 312 facing the headrest region to provide cushioning for a child seated within the child safety seat 24. In an embodiment, a channel 316 is formed between the first and second portions 312, 314, and a portion of the textile is disposed within the channel 316 to couple the textile to the headrest 46. However, any suitable means for attaching the textile to the headrest 46 is contemplated herein.

[0228] The headrest 46 can include at least one shoulder harness guide 320 having an opening 322 therein for receiving a vehicle safety belt. The shoulder harness guide 320 can be integrally formed with the main body of the headrest, or alternatively, can be a separate component attached thereto. As shown inFigures 24A to 24C As shown in FIG. 3, the at least one shoulder harness guide 320 can be aligned with and installed as an extension of a portion of the body 300. For example, the at least one shoulder harness guide 320 can be positioned at a bottom surface of one or both of the first head side member 304 and the second head side member 308. The shoulder harness guide 320 can have a complementary shape to the adjacent portion of the body 300 such that the shoulder harness guide is flush with the body and defines a portion of the profile of the headrest 46. The at least one shoulder harness guide 320 can be permanently affixed to the body 300, or alternatively can be removably connected thereto. In the illustrated non-limiting embodiment, the shoulder harness guide 320 is attached to the body 300 using one or more fasteners, for example at a location between the first portion 312 and the second portion 314. However, it should be appreciated that any suitable means for removably connecting the shoulder harness guide 320 to the body 300 of the headrest 46 at any location is within the scope of the present disclosure.

[0229] The seat bottom portion 28 of the child safety seat 24 can include a seat support surface 50 that generally faces upward and extends from a first or front end 52 to a second or rear end 54 of the seat bottom portion 28. A first seat side member 56 can be disposed at a first side 58 of the seat support surface 50, and a second seat side member 60 can be disposed at a second, opposite side 62 of the seat support surface 50. The first seat side member 56 and the second seat side member 60 extend upward and from the left and right sides of the seat portion. The seat support surface 50, as well as the first seat side member 56 and the second seat side member 60, in combination define an area within which at least a portion of a child’s lower body can be received.

[0230] As shown, the seat side members 56, 60 extend at an angle from the seat support surface 50. The angle of the first seat side member 56 relative to the seat support surface 50 can be the same as the angle of the first upright side member 36 relative to the upright support surface 30, but need not be. Similarly, the angle of the second seat side member 60 relative to the seat support surface 50 can be the same as the angle of the second upright side member 40 relative to the upright support surface 30, but need not be.

[0231] In the illustrated non-limiting embodiment, each seat side member 56, 60 has a slot 66 formed therein that is configured to act as a leg harness guide during at least one mode of use of the child safety seat 24. In some modes of operation of the child safety seat 24, the slot 66 can be configured to receive and position a leg harness portion of a vehicle restraint or a separate restraint harness to secure a child within the child safety seat 24. As will be described in greater detail, the rotational configuration and / or the recline of the child safety seat 24 can be adjusted when the child safety seat 24 is connected to the support base 22.

[0232] Child safety seat 24 generally includes a first booster portion and a second booster portion, and in one embodiment, seat back portion 26 can be considered the first booster portion and seat bottom portion 28 can be considered the second booster portion. However, embodiments in which seat bottom portion 28 is the first booster portion and seat back portion 26 is the second booster portion are also contemplated herein. The first booster portion can, but need not, be configured to be removably coupled to the second booster portion. In Figure 20A and 20B In the non-limiting embodiment shown in FIGS. 1-3, seat back portion 26 includes at least one seat back engagement feature 67, and seat bottom portion 28 includes at least one seat bottom engagement feature 68 that is selectively engageable with the corresponding seat back engagement feature. As shown, seat back engagement feature 67 can be a protrusion extending from near second end 34, and seat bottom engagement feature 68 can be a corresponding recess or opening formed in the surface of seat bottom portion 28 and aligned with the protrusion. Thus, the protrusion can be received within the recess to couple seat back portion 26 to seat bottom portion 28. However, embodiments in which seat bottom engagement feature 68 is the protrusion and seat back engagement feature 67 is the recess are also contemplated herein. Furthermore, other suitable mechanisms for removably coupling seat back portion 26 to seat bottom portion 28 are within the scope of the present disclosure.

[0233] Support base 22 for mounting child safety seat 24 includes a base body having a base seat portion 70 and a base rear portion 72 (see Figure 1 ). Suitable materials for manufacturing the base body include, but are not limited to, rigid plastic or composite materials, for example. Base seat portion 70 and base rear portion 72 can be integrally formed as a single body, or alternatively can be formed by separate components that are removably or permanently connected together.

[0234] Referring now to Figure 2In the illustrated non-limiting embodiment, the support base 22 includes a first base member 74 having a bottom surface 76 suitable for placement on a support surface such as a vehicle seat 10, and a second base member 78 coupled to the first base member 74. The first base member 74 may be a reclining leg and / or the second base member 78 may include a rigid frame 80 at least partially contained within a structural housing 82. At least a portion of the second base member 78 may be positioned overlapping the upper surface 84 of the first base member 74. In the illustrated non-limiting embodiment, the first base member 74 is arranged only at the base seat portion 70 of the support base 22, and the second base member 78 forms part of both the rear portion 72 of the base and the base seat portion 70. However, embodiments in which the first base member 74 forms part of both the rear portion 72 of the base and the base seat portion 70 are also covered herein. Referring to the figures, in one embodiment, the support base 22 includes a third base member 86, such as a spinner positioned overlapping the second base member 78. The third base component 86 includes a base component seat portion 88 located at the base seat portion 70 of the support base 22, and may include a base component rear portion 90 extending at an angle from the base component seat portion 88. As will be described in more detail, at least a portion of the child safety seat 24 may be detachably attached to the third base component 86 of the support base 22.

[0235] The third base component 86, and therefore any part of the child safety seat 24 connected to the third base component 86, can rotate about an axis relative to the first base component 74 and the second base component 78. In one embodiment, the third base component 86 includes a spin bracket 92. The spin bracket 92 can have different configurations, such as Figure 2 , 3 As shown in 25 and 26. In Figure 2 and 3 In the non-limiting embodiments shown, the spin carrier 92 is at least partially included within the structural housing or body 94. However, embodiments that do not include the body 94 are also covered herein. For example, in Figures 25 to 27 In the embodiment shown, the distal ends of the rear portion 90 of the base component and the spin bracket 92 can be positioned between the seat back panel 33 and the seat back, such as the upright support surface 30. The seat back panel 33 may include protrusions or tabs 96 that can be inserted into corresponding recesses or openings (not shown) formed in the seat portion 88 of the base component to attach the third base component to the seat back portion 26.

[0236] refer to Figure 70Storage compartment 700 may be formed in a portion of support base 22, for example, at the rear portion 72 of the base. While storage compartment 700 is generally shown as being formed only in the second base member 78, embodiments in which storage compartment 700 is formed only in the first base member 74, or alternatively formed by a combination of the first base member 74 and the second base member 78, are also within the scope of this invention. In one embodiment, one or more latches (not shown), such as those of a latching system for attaching a child seat system 20 to a vehicle seat, may be held within storage compartment 700. As shown, cover 702 may be movable relative to support base 22 between an open position and a closed position (not shown) to selectively seal storage compartment 700. In one embodiment, cover 702 may be removed from support base 22. However, in other embodiments, cover 702 may be movably coupled, for example, pivotally or hingedly coupled to support base 22, such that cover 702 remains attached to support base when cover 504 is in both the open and closed positions.

[0237] The second base component 78 at the base seat portion 70 may include a profile or opening 97 (see...). Figure 29 Furthermore, a portion of the third base component 86 can be housed within the opening 97. In one embodiment, as... Figure 3 , 4 As shown in Figures 25 to 27, near the bottom of the third base component 86, the spin bracket 92 includes a circular flange 98, for example, having an edge that has been rolled or otherwise formed to form a seat anchor or edge 100. A portion of the second base component 78, such as a rigid frame 80, may include one or more hooks or anchors 102 (see Figure 2). Figure 3 and 25 ), which has a curvature configured to engage the edge 100. In, for example Figure 22 and 27 In some embodiments shown, the bottom spin-on cap 99 may be vertically positioned below the circular flange 98. In such embodiments, the bottom spin-on cap 99 may, but does not need to, be mounted to the circular flange 98.

[0238] In one embodiment, the third base component 86 is rotatable about an axis relative to the first base component 74 and the second base component 78 of the support base 22 among multiple configurations. In one embodiment, the third base component 86, and therefore the child safety seat 24 to which it is connected, is rotatable relative to both the first base component 74 and the second base component 78 of the support base 22. For example, engagement between the edge 100 and a corresponding hook 102 formed on the second base component 78 can define the rotational path of the third base component 86 relative to the first base component 74 and the second base component 78, and thus define the rotational path of the child safety seat 24 relative to the support base 22. Figure 4 , 16 As shown in Figure 17, the third base component 86, and therefore the child safety seat 24 that can be connected to the third base component 86, can be in a first rotational configuration, for example, in which the child safety seat 24 is in a forward-facing position. Figure 1 and 3 The configuration of the child safety seat 24 is the same as the second rotating configuration, for example, where the child safety seat 24 is in a rear-facing position. Figure 4 and 16 The child safety seat 24 can rotate between the first and second rotating configurations. However, it should be understood that embodiments in which the child safety seat 24 can be positioned in one or more additional configurations between the first and second rotating configurations are also within the scope of this invention.

[0239] The spin lock 330 can be used to selectively lock the third base component 86, and thus the child safety seat 24 connected to the third base component 86, in one of a plurality of configurations relative to the support base 22. Reference Figure 28A and 28B An example of the spinlock 330 is shown in more detail below. As shown, the spinlock 330 is disposed within a portion of the second base member 78 at the base seat portion 70 of the support base 22. Referring to the illustrated non-limiting embodiment, the spinlock 330 includes a centrally positioned link 332 rotatable about an axis X. In one embodiment, the link 332 may be suitably mounted to the support base 22 via bolts or other suitable fasteners. As shown, the link 332 may have two end segments 334 extending outward therefrom, for example, positioned on opposite sides of the link 332 relative to the axis of rotation. A plurality of locking pins 336, such as two locking pins, are connected to the link 332. For example, a first end 338 of each locking pin 336 is connected to a corresponding end segment 334 of the link 332. As shown, the locking pins 336 may extend from the link 332 in opposite directions.

[0240] Locking pin 336 can be in a first locked position in which the child safety seat 24 cannot rotate relative to the support base 22. Figure 28A) between a first locked position in which the child safety seat 24 is locked in place relative to the support base 22 and a second unlocked position in which the child safety seat 24 is free to rotate relative to the support base 22. Figure 28B ) and a second unlocked position in which the child safety seat 24 is free to rotate relative to the support base 22. When each of the lock pins 336, and thus the spin lock 330, is in the locked position, the second opposing end 340 of the lock pin 336 is received within a corresponding lock segment 342, such as a groove or opening formed in a portion of the support base 22. When the lock pin 336, and thus the spin lock 330, is in the second unlocked position, the second end 340 of the lock pin 336 is separated from the lock segment 342, allowing the child safety seat 24 to rotate relative to the second base component 78. In the illustrated non-limiting embodiment, the plurality of lock segments 342 are formed in the second base component 78. However, embodiments in which the plurality of lock segments 342 are formed in the first base component 74 or another suitable component are also contemplated herein. In one embodiment, a biasing component (not shown), such as a torsion spring, is operably coupled to the link 332 to bias the link 332, and thus the lock pin 336, to the first locked position.

[0241] With continued reference to Figure 28A and 28B , and further reference to Figures 29 to 32B , at least one actuator 350 is operably coupled to at least one of the lock pins 336. In the illustrated non-limiting embodiment, a plurality of actuators are operably coupled to the spin lock 330. As shown, a first actuator 350a is operably coupled to the first lock pin 336 and a second actuator 350b is operably coupled to the second lock pin 336. Each actuator 350a, 350b can be independently or individually operated to transition the lock pin 336 from the locked position to the unlocked position. Alternatively or additionally, the first actuator 350a and the second actuator 350b can be operated simultaneously to transition the lock pin 336 from the locked position to the unlocked position.

[0242] In the illustrated non-limiting embodiment, the plurality of actuators 350a, 350b are substantially identical and include a handle 352 disposed at an outer surface of the child safety seat 24. The handle 352 can be directly or indirectly connected to the lock pin 336. As shown, each handle 352 is operably coupled to the corresponding lock pin by a wire, cable, or other suitable tension member 354. The handle 352 can be part of or integral with a drive component 356 that is pivotally mounted to the child safety seat 24. In such embodiments, the drive component 356 is positioned such that the handle 352 extends through an opening in, for example, the seat back shell 29 and is exposed at the exterior of the child safety seat 24. However, embodiments in which the handle 352 is separate from the drive component 356 and is operably coupled to the drive component are also contemplated herein. An engagement link 360 connected to the tension member 354 can be movably coupled to the drive component 356.

[0243] In the illustrated non-limiting embodiment, the drive member 356 has an angled slot 362 formed therein, and a pin 364 extending through an opening 366 formed in the engagement link 360, e.g. near one end thereof, is also received within the slot 362. The pin 364 is configured to translate within the slot 362 in response to rotation of the drive member 356. Due to the angled configuration of the slot 362, this translation of the pin 364 and engagement link 360 relative to the drive member 356 exerts a force on the tension member 354. As Figure 31 illustrated, the drive member 356, engagement link 360, and a portion of the tension member 354 can be embedded within the seat back portion 26, e.g. between the seat back 27 and the seat back shell 29.

[0244] To operate the actuator 350a to unlock the spin lock 330, a user exerts a force Fl on the handle 352 Figure 32A ). In one embodiment, the user operates to rotate the handle 352 forward. However, embodiments in which the handle 352 moves in another manner, e.g. translates inwardly or pushes or pulls outwardly, are also within the scope of the present disclosure. This movement of the handle causes the drive member 356 to rotate about its axis, such that the pin 364 of the engagement link 360 moves upwardly within the slot 362 (see Figure 32B ). Accordingly, in response to the force exerted on the handle 352, a force is exerted on the corresponding lock pin 336 in a direction opposite to the bias of the biasing member. Movement or translation of the first lock pin 336 causes the link 332 to rotate about its axis X against the bias of the biasing member. Because the second lock pin 336 is also coupled to the link 332, rotation of the link 332 via the first lock pin 336 causes a similar inward movement of the second lock pin 336. Via this inward movement, the second end 340 of both lock pins 336 disengage from the corresponding lock segment 342 of the support base 22. With the actuator 350a, 350b operated and the lock pins 336 disengaged from the lock segments 342, the user can then rotate the child safety seat 24 to a desired rotational configuration relative to the support base 22.

[0245] Once the child safety seat 24 has reached the desired rotational configuration, the user will release the actuator 350a, 350b. Upon release of the actuator 350a, 350b, the biasing force of the biasing member will cause the link 332 to rotate and the lock pins 336 to move outwardly, e.g. translate, into engagement with the corresponding lock segment 342 associated with the rotational configuration of the child safety seat 24. This force exerted on the tension member 354 via this outward movement causes the engagement link 360 to translate relative to the slot 362, and the drive member 356 to rotate about its axis back to the unactuated position. It will be appreciated that the spin lock 330 illustrated and described herein is intended only as an example and any suitable configuration is within the scope of the present disclosure.

[0246] Another embodiment of a spin lock 400 is shown in Figures 38 to 40 . Similar to the previous embodiment, the spin lock 400 includes a central portion 402 movably mounted to the child seat 24. In the non-limiting embodiment shown, the central portion 402 is translatable relative to the child seat 24. It should be appreciated that the child seat 24 can be rotationally coupled to the support base 22 at a location other than the spin lock 400 via a bolt or other suitable fastener (403).

[0247] As shown, the central portion 402 can include at least one engagement slot 404, such as a pair of engagement slots. At least one lock pin 406 can be fixed to the central portion 402. In the non-limiting embodiment shown, a pair of lock pins 406 are movably coupled to the pair of engagement slots 404, respectively. As shown, the lock pins 406 can extend outwardly from the central portion 402 in opposite directions.

[0248] The lock pins 406 can be transitioned between a first locked position (Fig. 1) in which the child safety seat 24 is not rotatable relative to the support base 22, Figure 39A and a second unlocked position (Fig. 2) in which the child safety seat 24 is freely rotatable relative to the support base 22. Figure 39B When each of the lock pins 406, and thus the spin lock 400, is in the locked position, the distal ends 408 of the lock pins 406 are received within corresponding lock segments (not shown) formed in a portion of the support base 22. When the lock pins 406, and thus the spin lock 400, are in the second unlocked position, the distal ends 408 of the lock pins 406 are separated from the lock segments, allowing the child safety seat 24 to rotate relative to the support base 22.

[0249] An actuator 410 (Fig. 3) Figure 40 operably coupled to the central portion 402 is operable to transition the spin lock 400 between the locked position and the unlocked position. In the non-limiting embodiment, the actuator is shown to be located at the upright side member 36 of the seat back portion 28 of the child seat 24. However, embodiments in which the actuator 410 of the spin lock is disposed in another location about the child seat 24 or even about the support base 22 are contemplated herein. When operated, the actuator 410 applies a force to the central portion 402. As shown, the engagement slots 404 formed in the central portion 402 are disposed at a non-parallel angle relative to the direction of movement of the central portion 402. Accordingly, the lock pins 406 are configured to translate inwardly as the lock pins 406 move within the engagement slots 404 in response to the actuator 410 applying a force to the central portion 402.

[0250] In Figures 71A to 72Yet another embodiment of a spin lock 800 is shown in FIG. 8. Similar to the previous embodiments, the spin lock 800 includes a centrally located link 802 that is rotatable about an axis X. The link 802 can be mounted to the support base 22 via bolts or other suitable fasteners. As shown, the link 802 can have two end segments 804 extending outwardly therefrom, e.g., disposed on opposite sides of the link 802 relative to the axis of rotation X. A plurality of lock pins 806, 808 can be connected to the link 802. Unlike the previously described embodiments in which the two lock pins can be substantially identical, in the illustrated non-limiting embodiment, a first lock pin 806 has a first configuration and a second lock 808 has a second configuration that is different than the first configuration. As shown, the first lock pin 806 can be generally rectangular in shape such that a first end 810 and a second end 812 of the first lock pin 808 are coaxial. The first end 810 of the first lock pin 806 can be connected to the end segments 804 of the link 802, and the second end 812 of the first lock pin 808 extends outwardly toward the outer perimeter of the support base 22. The second lock pin 808 can include a first segment 814 having a generally curved or arcuate profile and a second segment 816 having a rectangular configuration coupled to or integral with the first segment 816. For example, a first end 818 of the second lock pin 808 formed at the first arcuate segment 814 can be connected to the end segments 804 of the link 802, and a second end 820 of the second lock pin 808 disposed at the second segment 816 can extend radially outwardly from the link 802. As shown, the first lock pin 806 and the second segment 816 of the second lock pin 808 can be coaxial. Further, this axis of the first lock pin 806 and the second segment 816 of the second lock pin 808 can be spaced apart from or offset from, and thus not intersect, the axis of rotation X of the link 802.

[0251] The first lock pin 806 and the second lock pin 808 are movable between a first locked position (FIG. 8) in which the child safety seat 24 is not rotatable relative to the support base 22, Figure 71A and a second unlocked position (FIG. 9) in which the child safety seat 24 is freely rotatable relative to the support base 22. Figure 71B When in the locked position, the second ends 812, 820 of the lock pins 806, 808 are received within corresponding lock segments (not shown) formed in a portion of the support base 22. When the lock pins 806, 808, and thus the spin lock 800, are in the second unlocked position, the second ends 812, 820 of the lock pins 806, 808 are separated from the lock segments, allowing the child safety seat 24 to rotate relative to the support base 22.

[0252] In the illustrated non-limiting embodiment, a portion of the first and second locking pins 806, 808, such as the second segment 816, has a slot 822, 824 formed therein, and a pin or fastener 826, 828 is disposed within the respective slot 822, 824. This engagement between the pin 826, 828 and the corresponding slot 822, 824 defines a path of movement for each of the first and second locking pins 806, 808. As the spin lock 800 is transitioned between the locked and unlocked positions, each slot 822, 824 translates relative to the respective pin 826, 828. The pins 826, 828 can be disposed adjacent a first end of the slots 822, 824, such as the end of the slots 822, 824 closest to the link 802 when the spin lock 800 is in the locked configuration, and the pins 826, 828 can be disposed adjacent a second, opposite end of the slots 822, 824 when the spin lock 800 is in the unlocked configuration.

[0253] At least one biasing mechanism is operably coupled to the spin lock 800 to bias the first and second locking pins 806, 808 radially outward toward the locked position. In one embodiment, the biasing mechanism is coupled to the link 802. However, in other embodiments, such as that illustrated in the figures, a respective biasing component 830, 832, such as a coil spring, is operably coupled to each of the first and second locking pins 806, 808 and is operable to bias the first and second locking pins 806, 808 to the first, locked position.

[0254] The actuator, illustratively shown at 840, Figure 72 is operably coupled to the spin lock 800. In the illustrated non-limiting embodiment, the link 802 includes a radially extending actuation tab 836, and the actuator 840 is coupled to the actuation tab 836 via a link mechanism or tension member 838. Application of a force to the actuator 840 is to rotate the link 802 about its axis X. This rotation will apply a force to the first and second locking pins 806, 808, causing the locking pins 806, 808 to translate from the locked position to the unlocked position. While the locking pins 806, 808 are held in the unlocked position via the application of the force to the actuator 840, the second base component 78 can be translated relative to the first base component 74. Further, the actuator 840 can be biased to a normal position in response to removal of the force applied to the actuator 840. The actuator 840 can be located in any suitable location about the child safety seat 24, such as at an outer surface of the upright side components. Alternatively, the actuator 840 can be located at the support base, such as at the first base component 76 or the second base component 78.

[0255] The at least one base anchoring member 104 can be fixedly connected to a portion of the second base member 78. For example, the base anchoring member 104 can be part of the frame 80 and extend through an opening formed in the structural shell 82 (see Figure 2 While the illustrated non-limiting embodiment includes a base anchoring member 104 disposed near the distal end 106 of the second base member 78 at the base rear portion 72 of the support base 22, it should be appreciated that the base anchoring member 104 can be disposed in any suitable location. The base anchoring member 104 can be connected to a corresponding seat anchoring member 108. In one embodiment, the seat anchoring member 108 is located at the third base member 86. For example, the seat anchoring member 108 can be disposed at the base member rear portion 90 such that the base anchoring member 104 can be connected with the seat anchoring member when the child safety seat 24 is connected to the third base member 86 in a forward-facing configuration. In the illustrated non-limiting embodiment, the seat anchoring member 108 includes a wave-shaped flange or groove that is complementary to the base anchoring member 104. In other embodiments, the seat anchoring member 108 can be disposed at the child safety seat 24. For example, in the non-limiting embodiments of Figs. 1 and 2, the seat anchoring member 108 protrudes from the seat back portion 26, such as from an outer surface 35 thereof. Figure 21B and 23

[0256] As will be described in greater detail below, the base anchoring member 104 can also be connected to the seat anchoring member 108 regardless of the angle of recline of the child safety seat 24 relative to the support base 22. This connection between the base anchoring member 104 and the seat anchoring member 108 stabilizes the seat back portion 26 of the child safety seat 24. In such embodiments, the base anchoring member 104 can not be connectable to the seat anchoring member 108 when the child safety seat 24 is in a rear-facing configuration. However, it should be appreciated that the base anchoring member 104 can be adapted for use with seat anchoring members 108 disposed at any location about the third base member 86 and / or the child safety seat 24.

[0257] ​Alternatively or additionally, the child safety seat 24, when coupled to the support base 22, can be movable relative to at least a portion of the support base 22 to adjust the recline of the child safety seat 24. In one embodiment, the second base component 78 is movable (e.g., translated) relative to the first base component 74 along a recline path to control the recline or tilt of the child safety seat 24. Because the third base component 86 is coupled to the second base component 78, the third base component 86 and the child safety seat 24, if connected thereto, can move in unison with the second base component 78 between, for example, a first position associated with an upright position of the child safety seat 24 and a second position associated with a tilted position of the child safety seat 24. However, it should be appreciated that the first and second tilted positions can each be a position in a recline arrangement having a different degree of recline. Moreover, embodiments in which the child safety seat 24 can be arranged in any one of a plurality of tilted positions between the upright position and the tilted position are also contemplated herein.

[0258] Moreover, the support base 22 can include a recline lock mechanism operable to selectively lock the second base component 78, and thus the child safety seat 24 coupled thereto via the third base component 86, at one of a plurality of positions along the recline path. An example of a recline lock mechanism 420 is shown in Figures 41 to 44B . As shown, the recline lock mechanism 420 includes a centrally positioned pivot link 422 rotatable about an axis. As shown, the pivot link 422 can have two end segments 424 extending outwardly therefrom, e.g., disposed on opposite sides of the pivot link 422 relative to its axis of rotation. At least one recline pin 426, e.g., two recline pins, is connected to the pivot link 422. As shown, the recline pins 426 can extend in opposite directions from the pivot link 422.

[0259] The plurality of recline pins can be in a first locked position in which the second base component 78 is not movable relative to the first base component 74 Figure 42 , 43A , 44A) and a second unlocked position in which the second base component 78, and thus the child seat 24 rotatably coupled thereto, is free to move relative to the first base component 74 to adjust the recline of the second base component 78 and the child seat 24 Figure 43B and 44B) are uniformly transformed. When each of the recline pins 426 is in the locked position, the second end 428 of the recline pin 426 is received in a corresponding lock opening 430 formed in a portion of the first base component 74, such as in a sidewall of the first base component. When the recline pin 426 is in the second, unlocked position, the second end 428 of the recline pin 426 is disengaged or disassociated from the lock opening 430, thereby allowing the second base component 78 and the child seat 24 to be tilted or reclined.

[0260] In one embodiment, a respective biasing component 432, such as a coil spring, is operably coupled to each of the recline pins 426 and is operable to bias the recline pins 426 to the first, locked position. An actuator 434 is operably coupled to the recline lock mechanism 420. In the illustrated, non-limiting embodiment, the pivot link 422 includes a radially extending actuation tab 436, and the actuator 434 is coupled to the actuation tab 436 via a linkage mechanism or tension member 438. Application of force to the actuator 434 can be used to rotate the pivot link 422 about its axis. This rotation will apply a force to the recline pins 426, causing the recline pins 426 to translate from the locked position to the unlocked position. While the recline pins 426 are held in the unlocked position via application of force to the actuator 434, the second base component 78 can be translated relative to the first base component 74. The actuator 434 can be biased to a normal position in response to removal of the force applied to the actuator 434. A biasing mechanism (not shown) can be directly coupled to the actuator 434, or alternatively, the biasing mechanism can be associated with an intermediate assembly, as shown in Figure 44A and 44B shown in

[0261] As shown in Figure 42 , the first base component 74 includes a plurality of lock openings 430, each associated with a different tilt or recline of the child seat 24. The second base component 78 is thus movable to a position in which the ends 428 of the recline pins 426 are aligned with and configured to engage a respective lock opening of the plurality of lock openings 430. It will be appreciated that the recline lock mechanism 420 shown and described herein is intended only as an example, and that any mechanism suitable for selectively locking and unlocking movement of the child seat 24 and / or the second base component 78 relative to the first base component 74 to adjust the tilt of the child seat 24 is within the scope of the present disclosure. Further, the child safety seat 24 can be rotated relative to the support base between a forward-facing configuration and a rear-facing configuration when the child seat is locked in any of a plurality of reclined positions.

[0262] Reference is now made to Figures 45 to 47In one embodiment, the support base 22 includes a seat belt tensioner 450. In the illustrated, non-limiting embodiment, an opening 452 is formed in a base rear portion of the support base 22, such as in the second base component 78, and the seat belt tensioner 450 is receivable within the opening 452. The profile of the seat belt tensioner 450 can be complementary to the profile of the opening 452 such that substantially the entirety of the seat belt tensioner 450 is receivable within the opening 452. A vehicle seat belt associated with the vehicle seat 10 is positionable along a seat belt receiving path defined between a surface of the base rear portion 72 of the support base 22 and the seat belt tensioner 450. In one embodiment, the seat belt tensioner 450 is selectively movable relative to the support base 22 to adjust the tension applied to the vehicle seat belt 12 along the vehicle seat belt receiving path. For example, the seat belt tensioner 450 can be configured to pivot about at least one axis between an open position Figure 45 and 46 ) and a closed position Figure 38 ) to selectively tension a portion of the vehicle seat belt 12 sandwiched between the seat belt tensioner 450 and the opening 452 to couple the support base 22 to the vehicle seat belt 12, thereby limiting movement of the support base 22 relative to the vehicle seat 10.

[0263] A seat belt tensioner locking mechanism 470 can be used to retain the seat belt tensioner 450 in the closed position. As shown, a portion of the seat belt tensioner 450, such as near its top end 456, includes a rigid shaft or pin 458. One or more slots 460 can be formed at a surface 462 of the seat belt tensioner 450 facing the opening 452 and can extend to the shaft 458 to define a passageway for accessing the shaft 458. At least one clasp 472 is disposed within the opening 452 at a location aligned with the slots 460 formed in the surface 462 and is coupleable to the shaft 458. In one embodiment, each clasp 472 includes a movable component 474 and a fixed component 476. When the clasp 472 is open Figure 46 ), the movable component 474 is disposed at a non-parallel angle relative to the fixed component 476. Thus, the ends of the movable component 474 and the fixed component 476 are separated from one another and define an opening for receiving the shaft 458. When the clasp 472 is closed Figure 45 ), the movable component 474 is rotated toward the fixed component 476. In the closed configuration, the movable component 474 can be oriented substantially parallel to the fixed component 476, and the distal ends of the movable component 474 and the fixed component 476 can overlap one another. Thus, when closed, the opening 478 defined between the movable component 474 and the fixed component 476 is substantially enclosed, thereby locking the shaft 458 in place relative to the clasp.

[0264] A biasing mechanism (not shown) can be associated with the movable member 474 of the buckle 472 and operable to bias the movable member 474 toward the fixed member 476 toward the closed position. As the seat belt tensioner 450 pivots toward the opening 452 and the buckle 472, the shaft 458 can engage a forward-facing surface 480 of the movable member 474. In the illustrated non-limiting embodiment, the forward-facing surface 480 of the movable member 474 is contoured, e.g., sloped, such that engagement between the shaft 458 and the forward-facing surface 480 resists the bias of the biasing mechanism urging the movable member 474 away from the fixed member 476. Once the shaft 458 clears the forward-facing surface 480, the bias will cause the movable member 474 to rotate toward the fixed member 476 such that the shaft 458 is enclosed within the opening 478.

[0265] The actuator 482 is operably coupled to the at least one buckle 472 to selectively open the at least one buckle 472 to release the seat belt tensioner 450. While the actuator 482 is shown positioned proximate to the seat belt tensioner locking mechanism 470, it should be appreciated that embodiments in which the actuator 482 is positioned remotely therefrom are within the scope of the present disclosure. The actuator 482 is operably coupled to the movable member 474 of the at least one buckle 472 by a linkage mechanism 484 (see Figure 45 ) or other suitable connection. Thus, when a force is applied to the actuator 482, e.g., when the actuator 482 is pressed, the force is transmitted to the movable member 474 via the linkage mechanism 484. The force resists the bias of the biasing mechanism, in turn causing the movable member 474 to disengage from the fixed member 476. In the disengaged or open position, the seat belt tensioner 450 can be moved away from the seat belt opening 452.

[0266] As indicated above, at least a portion of the child safety seat 24 can be removably connected to the third base component 86. In one embodiment, the seat bottom portion 28 is detachable from the third base component 86, e.g., from the base component seat portion 88 thereof. Referring to Figures 5 to 7 and 33, the base component seat portion 88 can include at least one upwardly projecting attachment component, e.g., extending from the surface 110 in a direction between a rear end and a front end thereof. Figures 5 to 7The non-limiting embodiments shown in FIGS. 33 include a first attachment component 120 disposed generally centrally between the lateral sides of the base component seat portion 88. Additionally, two substantially identical second attachment components 122 can be laterally spaced apart from a first side 124 and a second side 126 of the first attachment component 120, respectively. It should be appreciated, however, that embodiments including a single attachment component disposed at another location about the base component seat portion 88 and / or at least one attachment component are also contemplated herein. Each attachment component 120, 122 can be shaped as a tube, a bar, a block, or any other suitable shape. The one or more attachment components 120, 122 can be formed of a suitably rigid material and can be fixedly attached to the base component seat portion 88, or alternatively, can be integrally formed with the main body of the third base component 86.

[0267] As Figure 6 , 7 , 36A and 36B, at least one positioning feature 130, such as a recess, is formed in one or more surfaces of the seat bottom portion 28 of the child safety seat 24, such as a bottom surface 132 of the seat bottom portion 28 configured to dock with the upper surface 110 of the seat bottom portion 28. Each seat positioning feature 130 can be complementary in size and / or shape to a corresponding one of the attachment components 120, 122 such that the attachment component can be received therein. This alignment and / or engagement between the attachment components 120, 122 and the seat positioning features 130 properly positions the seat bottom portion 28 adjacent to the base component seat portion 88.

[0268] In an embodiment, the seat bottom portion 28 of the child safety seat 24 is loosely positioned about the supporting base, such as about the base component seat portion 88. As used herein, the term "loosely positioned" describes embodiments in which the seat bottom portion is simply disposed in contact with the supporting base but the seat bottom portion is not otherwise connected thereto. Thus, in this loosely positioned configuration, a user can easily simply detach the seat bottom portion 28 from the supporting base 22 by lifting and / or rotating the seat bottom portion 28 away from the third base component 86. The weight of the passenger can be sufficient to restrain unwanted detachment of the seat bottom portion 28 from the third base component 86. In other embodiments, the seat bottom portion 28 can be coupled or attached to the third base component 86 via a booster locking mechanism. In such embodiments, the booster locking mechanism prevents unwanted detachment of the seat bottom portion 28 from the third base component 86. Thus, the booster locking mechanism must be deactivated, such as by disconnecting a corresponding portion of the booster locking mechanism before the seat bottom portion 28 is detached from the third base component 86.

[0269] Figure 34An example of a booster lock mechanism 370 is shown in FIG. 3. As shown, the booster lock mechanism 370 includes at least one locking member 372 movably mounted to the seat bottom portion 28. In the illustrated non-limiting embodiment, the locking member 372 is pivotally mounted to an underside of the seat bottom portion 28, for example, near the first seat side member 56 or the second seat side member 60. The locking member 372 includes an elongated body 374 having an engagement feature 376 disposed at a first end thereof and an actuation face 378 disposed, for example, near a second end thereof. The engagement feature 376 can be oriented at a non-parallel angle to the body. A biasing member (not shown), for example, a torsion spring, is operably coupled to the locking member 372 and is operable to bias the locking member 372 toward a first locked position (shown). In the locked position, the engagement feature 376 extending from the body 374 is disposed in contact or abuts a surface of the third base member 86.

[0270] An actuator 380 is operably coupled to the locking member 372. With continued reference to Figure 34 and further reference to Figure 35 , the actuator 380 includes a handle 382 disposed at an outer surface of the child safety seat 24. In the illustrated non-limiting embodiment, the handle 382 is disposed at an outer surface of the seat bottom portion 28, for example, at one of the first seat side member 56 or the second seat side member 60. The handle 382 can be directly or indirectly coupled to the locking member 372. As shown, an actuation member 384 can extend from a surface of the handle 382 toward an interior of the seat bottom portion 28. The actuation member 384 can be positioned in alignment with the actuation face 378 of the locking member 372.

[0271] To operate the actuator 380 to unlock the seat bottom portion 28 from the third base member 86, a user applies a force F2 to the handle 382. In one embodiment, the user is configured to push or translate the handle 382 inward. However, embodiments in which the handle 352 is moved in another manner, for example, pulled outward or rotated, are within the scope of the present disclosure. This movement of the handle 382 moves the actuation member 384 into engagement with and imparts a force to the actuation face 378. The force applied to the actuation face 378 resists the bias of the biasing member, thereby causing the locking member 372 to rotate about its axis to a second unlocked position. In this second unlocked position, the engagement feature 376 is separated or disengaged from the third base member 86. Although Figure 34The diagram shows only a single locking member 372, but it should be understood that embodiments including multiple locking members are within the scope of this invention. For example, the locking member 372 may be arranged adjacent to each of the first seat side member 56 or the second seat side member 60. In such embodiments, a single actuator may be operatively coupled to the plurality of locking members 372, or alternatively, a corresponding actuator 380 may be associated with a corresponding locking member 372.

[0272] refer to Figures 48 to 49B This illustrates another embodiment of the booster locking mechanism 500. The booster locking mechanism 500 includes at least one locking member 502 pivotally mounted to the seat base portion 28, for example, pivotally mounted to the underside of the seat base portion 28. In one embodiment, the locking member 502 is a latch plate. Similar to... Figure 34 and 35 In the previous embodiment shown, the latch plate 502 includes an engaging member 504 disposed at its first end and a releasing member 506, for example, disposed near its second end. A recess 508 may be defined between the engaging member 504 and the releasing member 506. A biasing mechanism 510, such as a torsion spring, may be operably coupled to the latch plate 502. In one embodiment, the biasing mechanism 510 is operable toward a first locked position ( Figure 49A ) Biased latch plate 502. In the first locked position, the pin or shaft 512 arranged at the third base member 86 is received in the recess 508 and / or engaged by the engagement member 504 of the latch plate 502.

[0273] The seat base portion 28 further includes an actuator 514 operably coupled to the booster locking mechanism 500. In the illustrated non-limiting embodiment, the actuator 514 is a release handle disposed on an outer surface of the seat base portion 28, such as its upper surface. The actuator 514 may be pivotally mounted to the seat base portion 28. When not actuated, the actuator 514 may be substantially flush with the upper surface of the seat base portion 28. In one embodiment, the axis of rotation of the actuator is parallel to the axis of rotation of the latch plate 502. A portion of the actuator 514, such as its distal end 516, is configured to contact the release member 506 of the latch plate 502. In response to lifting the actuator 514, the actuator 514 pivots about its axis such that the distal end 516 engages the release member 506 of the latch plate 502 and applies a force to the release member. This engagement causes the latch plate 502 to rotate in a direction opposite to the biasing force of the biasing mechanism 510. This movement of the latch plate 502 disengages the pin 512 and the engagement part 504 of the latch plate 502. Once disengaged, the seat base portion 28 can be separated from the rest of the child seat 24.

[0274] In some embodiments, the seat back portion 26 of the child safety seat 24 is not separable from the support base 22. However, in other embodiments, both the seat floor portion 28 and the seat back portion 26 are detachable from the third base component 86. More specifically, the seat floor portion 28 can be removably connected to the base component seat portion 88, and the seat back portion 26 can be removably connected to the base component rear portion 90 of the third base component 86. Furthermore, the seat floor portion 28 can be separable from the seat back portion 26, such that the seat floor portion 28 and the seat back portion 26 can be independently detached from the third base component 86.

[0275] In Figures 8 to 12 In the non-limiting embodiments shown in FIGS. 1-3, the seat back portion 26 includes at least one, and in some embodiments, a plurality of seat interlock features 140, such as a groove, recess, or opening. The base component rear portion 90 can similarly include at least one base interlock feature 142, such as a ledge, rib, or other protrusion, configured to engage, be received within, or rest against the corresponding seat interlock feature 140. This engagement between the at least one seat interlock feature 140 and the at least one base interlock feature 142 properly positions the base component rear portion 90 of the third base component 86 relative to the adjacent seat back portion 26.

[0276] In Figure 12 In the non-limiting embodiments shown in FIGS. 1-3, the seat back portion 26 includes at least one, and in some embodiments, a plurality of seat interlock features 140, such as a groove, recess, or opening. The base component rear portion 90 can similarly include at least one base interlock feature 142, such as a ledge, rib, or other protrusion, configured to engage, be received within, or rest against the corresponding seat interlock feature 140. This engagement between the at least one seat interlock feature 140 and the at least one base interlock feature 142 properly positions the base component rear portion 90 of the third base component 86 relative to the adjacent seat back portion 26.

[0277] In one embodiment, the base component rear portion 90 includes at least one base interlock feature 142 protruding from near the bottom thereof, and the seat back portion 26 includes at least one seat interlock feature 140, such as an opening, within which the base interlock feature can be received. As shown in FIG. 4, the base interlock feature 142 can be received within the seat interlock feature 140 in a first portion of the seat interlock feature 140. The base interlock feature 142 can then be moved, such as slid, to a second portion of the seat interlock feature 140. In the second portion of the seat interlock feature 140, the base interlock feature 142 can abut a plurality of surfaces of the seat back portion 26, such as the upper end 144 of the seat interlock feature 140, thereby limiting undesired separation of the base interlock feature 142 from the seat interlock feature 140. Figures 13A to 15As shown in the middle, the at least one base interlock feature 142 can extend through the seat back portion 26 such that at least a distal end 146 of the base interlock feature 142 is disposed generally adjacent to the upright support surface 30. The seat back portion 26 can include an engagement feature 150 that is movable relative to the upright support surface 30 to selectively engage the adjacent base interlock feature 142. In the illustrated non-limiting embodiment, the engagement feature 150 is a pin lock that includes a handle 152 and a pin 154 extending from the handle 152. The base interlock feature 142 includes an opening or through-hole 148, and a free end of the pin 154 can be received within the opening 148 to couple the base interlock feature 142, and thus the third base component 86, to the seat back portion 26.

[0278] The pin lock 150 can be translated into engagement with the base interlock feature 142. For example, the pin lock 150 can be configured to slide along an axis X between an unlocked position Figure 13A ) and a locked position Figure 13B ). In the unlocked position, a distal or free end of the pin 154 is spaced inwardly from the base interlock feature 142 and in the locked position, the pin 154 is received within the opening 148 of the base interlock feature 142. In some embodiments, the pin lock 150 can also be rotatable about an axis to retain the pin lock 150 in the locked position. As shown, the pin lock 150 can be rotatable out of the plane of the upright support surface 30 between a first position in which the handle 152 extends at a non-parallel angle to the adjacent upright support surface 30 and a second position in which the handle 152 is at a generally parallel angle to the adjacent upright support surface 30. The upright support surface 30 of the seat back portion 26 can have one or more grooves or recesses 156 formed therein such that at least a portion of the handle 152 is disposed within the recess 156 when the pin 154 is in the locked position and the handle 152 is in the second position. Alternatively or additionally, the pin 154 of the pin lock 150 can be disposed within a recess 156, such as the same recess or a different recess. With this configuration, the handle 152 and / or the pin 154 can be positioned at a location that avoids or minimizes contact with a passenger's back. Further, the handle 152 can include a tab, flange or other feature 158 that is configured to engage or interface with a corresponding surface of the recess 156 when the handle 152 is disposed in the second position. This engagement can prevent unwanted rotation of the handle 152 from the second position.

[0279] Although the translation and rotation of the locking pin 150 are described as occurring individually or sequentially, in other embodiments, the locking pin 150 rotates about axis X from a first position to a second position, causing the locking pin 150 to simultaneously translate along axis X between an unlocked position and a locked position. For example, a user can apply a downward force to handle 152, causing handle 152 to rotate about axis X, and as handle 152 rotates downward, the locking pin 150 slides laterally to engage with the through-hole 148 of the base interlocking feature 142. It should be understood that the engagement feature 150 and the interface with the corresponding base interlocking feature 142, as illustrated and described herein, are intended only as examples, and any suitable mechanism for removably attaching the third base component 86 to the seat back portion is covered herein.

[0280] A portion of the child safety seat system 20, such as the support base 22, may include a strap 200 operable to secure a child in the child safety seat system 20 when the child seat is in at least one of a plurality of configurations. In the non-limiting embodiment shown, the strap 200 is attached to and positioned adjacent to a third base component 86. Figures 5 to 8 The suspenders shown in the best example may include multiple straps, including but not limited to shoulder straps, waist belts and crotch straps.

[0281] In one embodiment, the suspender 200 includes a crotch strap that is generally positioned between the passenger's legs and has a webbing 202 and a buckle 204 at its distal end (also...). Figures 21A to 21C (As shown in the diagram). The harness 200 may additionally include a first strap 206 and a second strap 208, each having at least one piece of webbing and a latch 210 configured to selectively fasten to a buckle 204. The latch 210 may be releasably secured or fastened to the buckle 204 to secure a child in the child safety seat 24. Each of the first strap 206 and the second strap 208 may have a leg strap portion that can be positioned over the child's legs and a shoulder strap portion that can be positioned over the child's shoulders. In one embodiment, the leg strap portion and the shoulder strap portion of each strap 206, 208 are separate pieces of webbing coupled to the latch 210. In another embodiment, the leg strap portion and the shoulder strap portion are integrally formed via a single piece of webbing. In such embodiments, the latch 210 is movable relative to the webbing pieces, and portions of the webbing arranged on a first side of the latch 210 form the leg strap portion and portions of the webbing on a second side of the latch 210 form the shoulder strap portion.

[0282] In one embodiment, one end (not shown) of the webbing 202 of the crotch strap is attached to a portion of the support base 22, for example, to a third base component 86. Furthermore, the webbing 202 may extend through at least one attachment component, such as a first attachment component 120. As shown, the first attachment component 120 may define a recess 220 configured to receive and store the crotch strap when the harness 200 is not used to restrain a child in the child safety seat 24. For example, when the child safety seat 24 is used as a booster seat without the harness 200, the crotch strap can be retracted into the recess 220.

[0283] One end of the leg strap portion and / or one end of the shoulder strap portion of each strap 206, 208 may be attached to a portion of the support base 22, such as to the third base member 86. The ends of the leg strap portions and shoulder strap portions may be coupled to the third base member 86 at a location positioned below the upper surface 110 of the third base member. In the non-limiting embodiment shown, the end of each leg strap portion extends through a corresponding attachment member, such as a corresponding second attachment member 122.

[0284] The child safety seat 24 may have one or more openings formed therein to receive the straps of the harness 200 when the child safety seat 24 is mounted to the support base 22. For example, the shoulder strap portion of each harness 206, 208 may extend through a corresponding slit (not shown) formed in the upright support surface 30, or alternatively in a portion of the headrest 46. In such embodiments, the slit may extend to an edge of the upright support surface 30, such as the top edge, or to an edge of the headrest to provide a path for mounting the shoulder strap portion. In embodiments where the shoulder strap portion extends through a slit formed in the headrest 46, the harness is operably coupled to the headrest 46.

[0285] exist Figure 6 , 7 In the non-limiting embodiment shown in 21A, the seat base portion 28 of the child safety seat 24 has a first opening 230 formed in a seat positioning feature 130 configured to overlap with a first attachment member 120. The first opening 230 is sized to receive a lap belt buckle 204. Similarly, a slit 232 is associated with each corresponding seat positioning feature 130 configured to abut the second attachment member 122. As shown, the slit 232 forms an opening at each seat positioning feature 130 and may extend beyond the seat positioning feature 130 in at least one direction to the edge of the seat base portion 28, such as the rear 54.

[0286] During installation of the seat bottom portion 28 of the child safety seat 24 to the support base 22, the leg belt portion of each of the first and second harnesses 206, 208 is fed into the slot 232 and pulled into alignment with one of the seat positioning features 130. The buckle 204 of the crotch belt can similarly be threaded through the corresponding opening 230 formed in the respective seat positioning feature 130. With each of the leg belt portion and the crotch belt accessible at the seat support surface 50 at the seat bottom portion 28, the seat bottom portion 28 can then be lowered into position around the third base component 86 such that the seat positioning features 130 are aligned with and engaged by the corresponding first and second attachment components 120, 122. Once in position, the seat bottom portion 28 can be coupled to the third base component 86 and / or the seat back portion 26 as previously described. It should be appreciated that the harness 200 shown and described herein is intended only as an example and that harnesses having any suitable configuration are contemplated herein.

[0287] The seat bottom portion 28 can include at least one cup holder 520. In the non-limiting embodiment shown, the seat bottom portion 28 includes a first cup holder 520 positioned at the first seat side component 56 and a second cup holder 520 positioned at the second seat side component 60. While two cup holders 520 are shown, it should be appreciated that embodiments having only a single cup holder are also within the scope of the present disclosure. The cup holders 520 can be disposed forward of the slots 66 formed in the seat side components 56, 60 configured to receive and position the leg belt portion of a vehicle safety belt. In one embodiment, the cup holders 520 are positioned to provide sufficient seating space for a seat occupant while also providing sufficient clearance with respect to the support base 22 of the child restraint system 20. As shown, a textile 522 can be configured to be sewn under a portion of the cup holder 520, such as under the rim 524 of the cup holder 520. Figures 50 to 52

[0288] The cup holders 520 can be movable with respect to the seat bottom portion 28 and, in some embodiments, removable with respect thereto. In one embodiment, the cup holders 520 include a resilient or flexible snap finger 526 extending from a bottom 528 of the cup holder. The flexible snap finger 526 is configured to engage a protrusion 530 located at an interior of the seat bottom portion 28 to restrain separation of the cup holder 520 from the seat bottom portion 28. A flexible snap finger button 532 can be formed at an outer surface of the seat bottom portion 28 adjacent to a portion of the surface of the flexible snap finger 526. Application of force to the flexible snap finger button 532 moves the flexible snap finger 526 out of engagement with the protrusion 530 to allow separation of the cup holder 520 from the seat bottom portion 28. The removability of the cup holders 520 improves their, while also providing a final appearance with the adjacent textile 522. ​

[0289] Referring Figures 73 to 75B An example of a seat bottom portion 28 having a removable cup holder 900 similar to cup holder 520 is shown in greater detail. As shown, an actuation mechanism 902 associated with cup holder 900 is operable to selectively release cup holder 900 from seat bottom portion 28. In the illustrated non-limiting embodiment, actuation mechanism 902 is removably coupled to seat bottom portion 28. As shown, actuation mechanism 902 can be received within an opening 904 formed in seat bottom portion 28, for example directly beneath cup holder 900. Actuation mechanism 902 can include a body 906 having a first end 908 positionable at an exterior 910 of seat bottom portion 28, for example at seat side members 56, 60. Body 906 further includes a slot 912, and a flexible snap finger or other feature 914 of cup holder 900 can be received within slot 912. Body 906 can further define a surface 916 that can be engaged by an end 918 of feature 914 to limit separation of cup holder 900 from seat bottom portion 28. In one embodiment, a biasing structure 920 is mounted within an interior of seat bottom portion 28 adjacent to opening 904 and can be operably coupled to actuation mechanism 902, for example to a second end 922 thereof. Biasing structure 920 is operable to bias actuation mechanism 902 to an engaged position.

[0290] To disengage cup holder 90 from seat bottom portion 28, a user applies a force to first end 908 of actuation mechanism 902. The force opposes the biasing force of biasing mechanism 920, thereby causing body 906 to translate within opening 904 formed in seat bottom portion 28. As a result of this translation, surface 916 moves out of engagement with flexible snap finger 914, such that flexible snap finger 914 is disposed within slot 912 formed in body 906. When actuation mechanism 902 is in this disengaged position, cup holder 900 can be separated from or mounted relative to seat bottom portion 28. As shown, when cup holder 900 is not mounted about seat bottom portion 28, actuation mechanism 902 can be removed from seat bottom portion 28.

[0291] Referring now to Figures 16 to 19 various use configurations of child safety seat system 20 are shown. Figure 16 A use configuration of child safety seat system 20 associated with a baby or child having a weight of up to approximately 40 pounds is indicated. As shown, child safety seat 24 is connected to support base 22 and faces rearward. In the baby configuration, a child is restrained within child safety seat 24 using harness 200 that is integral with child safety seat system 20, and support base 22 can be mounted to vehicle seat 10 using an integral latching system or using vehicle safety belts. Figure 17Another configuration of the child safety seat system 20 shown is associated with use by toddlers or children older than two years or weighing between approximately 25 and 65 pounds. In this toddler configuration, the child safety seat 24 is attached to the support base 22 and faces forward. Similar to the infant configuration, in the toddler configuration, the child is restrained within the child safety seat 24 using the harness 200 of the child safety seat system 20, and the support base 22 can be mounted to the vehicle seat 10 using either an integrated latching system or the vehicle seatbelt.

[0292] In other embodiments, the child safety seat 24 may be configured as a booster seat. For example, in embodiments where the seat base portion 28 and the seat back portion 26 are separable from the support base 22, such as... Figure 18 As shown, the child safety seat 24 is positioned forward and in direct contact with the vehicle seat 10. In this high-back booster configuration, the child safety seat system 20 is intended for use by a child weighing between approximately forty pounds and approximately one hundred pounds. Furthermore, the child is restrained within the child safety seat 24 using the vehicle seatbelt. Although the child safety seat 24 is shown in a high-back booster configuration where the support base 22 is absent, it should be understood that the child safety seat 24 can also be used in booster configurations where the child safety seat system 20 is attached to the support base 22. In such embodiments, the child is restrained within the child safety seat 24 using the vehicle seatbelt and not using the harness 200.

[0293] Without backrest lifter configuration ( Figure 19 In this configuration, only the seat base portion 28 of the child safety seat 24 faces forward and is in direct contact with the vehicle seat. In the booster configuration without a backrest, the support base 22 and seat back portion 26 of the child safety seat 24 are absent. In this configuration, the child safety seat 24 is suitable for use by children weighing between approximately forty pounds and approximately one hundred and twenty pounds, and the child is restrained by the vehicle seatbelt relative to the seat base portion 28.

[0294] refer to Figures 36A to 37B The seat base portion 28 may include a stabilizing leg 390. As shown, the stabilizing leg 390 may be positioned at or adjacent to the bottom surface 132 of the seat base portion 28. The stabilizing leg 390 may be movable relative to the main body of the seat base portion 28. For example, the retractable stabilizing leg 390 may be in a first retracted configuration ( Figure 36A , 37A ) and the second extended configuration ( Figure 36B , 37B) from the adjacent surface 394 of the main body. In embodiments where the main body is sloped downward from the front edge 52 of the seat support surface 50 toward the rear of the seat bottom portion 28, the front surface 392 of the stability leg 390 can be generally aligned with the front edge 52 when in the stowed configuration. In the extended configuration, the bottom surface 396 of the stability leg 390 (in addition to the bottom surface 132 of the seat bottom portion 28) can be positioned in contact with the support surface, such as the vehicle seat 10. Thus, in the extended configuration, the footprint of the seat bottom portion 28 is expanded, thereby increasing the stability of the seat bottom portion 28.

[0295] In Figure 53 other embodiments shown in FIG. 54, the seat bottom portion 28 can have a plurality of separate stability legs 540. For example, a first stability leg 540 can be disposed proximate the first seat side member 56, and a second stability leg 540 can be disposed proximate the second seat side member 60. In embodiments including a plurality of discrete stability legs, the stability legs 540 can, but need not, have the same configuration. Similar to the previous embodiments, the plurality of stability legs 540 can be moved between a stowed configuration and an extended configuration relative to the seat bottom portion 28. In embodiments including a plurality of stability legs 540, the stability legs 540 can operate in unison, or alternatively can be moved independently of one another.

[0296] Referring to Figures 54 to 5 9, an example of a stability leg 540 is shown in greater detail. In the stowed configuration, the at least one stability leg 540 can be disposed at least partially, and in some embodiments entirely, within the interior of the seat bottom portion 28 (see Figure 55B ). In one embodiment, the at least one stability leg 540 has a sloped or angled front surface 542, and the front surface 52 is parallel or substantially parallel to an angled front surface 544 of the seat bottom portion 28 when the stability leg 540 is in the retracted configuration. In the extended configuration, the one or more stability legs 540 protrude beyond the surface of the seat bottom portion 28, such as the front surface 544. In Figure 55AIn the illustrated non-limiting embodiment, the bottom 546 of the stability leg 540 is spaced apart from and substantially aligned with the bottom 548 of the seat floor portion 28 when in the extended configuration. Thus, when the seat floor portion 28 is used independent of the remainder of the child seat 24, both the bottom 546 of the stability leg 540 and the bottom 548 of the seat floor portion 28 can be positioned on a support surface, such as the vehicle seat 10. In one embodiment, the angle of recline of the seat floor portion 28 relative to the vehicle seat when the at least one stability leg 540 is in the extended configuration is different than the angle of recline of the seat floor portion 28 when the at least one stability leg is in the stowed configuration.

[0297] In one embodiment, the at least one stability leg 540 is rotatable between the stowed configuration and the extended configuration. However, embodiments in which the at least one stability leg 540 can be translated or moved in another manner are also contemplated herein. In the illustrated non-limiting embodiment, each stability leg 540 of the seat floor portion 28 is operably coupled to a corresponding retractor 550 by a linkage 552. As shown, the retractor 550 can include an engagement member 554 and a leg member 556 that are arranged at an angle relative to one another. Although the leg member 556 and the engagement member 554 are shown as being generally perpendicular to one another, embodiments in which the members 554, 556 are separated at another angle are within the scope of the present disclosure. The retractor 550 is rotatable about an axis relative to the seat floor portion 28. The linkage 552 is pivotally coupled to one end of the leg member 554 and pivotally coupled to a portion of the stability leg 540, such as near the rear portion 558 of the stability leg 540.

[0298] A biasing mechanism 560 is operably coupled to the stability leg 540 to bias the stability leg 540 to the extended configuration. In the illustrated non-limiting embodiment, the biasing mechanism 560 is connected to the retractor 550; however, embodiments in which the biasing mechanism 560 is included at another suitable location are also contemplated herein. Upon separation of the seat floor portion 28 from the third base component 86 of the child seat 24, the biasing force of the biasing mechanism 560 will cause the corresponding stability leg 540 to automatically transition from the stowed configuration to the extended configuration. Thus, if the seat floor portion 28 is not attached to the child seat 24, the stability leg 540 extends to enhance the stability of the seat floor portion.

[0299] The stability leg 540 can automatically retract in response to the seat floor portion 28 being connected to the child seat 24, such as to the third base component 86. In one embodiment, the third base component 86 includes a height enhancer receiver 562 arranged in alignment with the corresponding retractor 550 Figure 57). When the seat bottom portion 28 is attached to the third base component 86, the riser receiver 562 engages the corresponding retractor 550. This engagement applies a force to the retractor 550, causing the retractor 550 to rotate about its axis, for example, toward the front of the seat bottom portion 28. This rotation of the retractor 550 drives a corresponding rotation of the stability leg 540 in the opposite direction. Thus, as the retractor 550 is rotated by the riser receiver 562, the stability leg 540 is rotated in the opposite direction, for example, toward the interior of the seat bottom portion 28 and the retractor 550, via the linkage 552. The retractor 550 remains in this rotated position while the seat bottom portion 28 remains coupled to the third base component 86. Upon separation of the seat bottom portion 28 from the third base component 86, the biasing force acting on the retractor 550 will cause the retractor 550 to rotate to drive the corresponding stability leg 540 forward to the extended configuration.

[0300] Reference is made to Figures 58 to 59B In another embodiment, rather than being operably coupled by a linkage, the leg component 554 of the retractor 550 can be directly secured to the stability leg 540 (via the pin 564). The operation of this configuration is substantially identical to that of the embodiment of Figures 54 to 57 described previously. As described previously, engagement with the riser receiver 562 drives the retractor 550, and thus the stability leg 540 coupled to the retractor 550, to the retracted configuration. Once the seat bottom portion 28 is separated from the third base component 86, the biasing force of the biasing mechanism 560 acting on the retractor 550 will automatically rotate the retractor 550, in turn driving the stability leg 540 forward to the extended configuration.

[0301] Reference is now made to Figures 60A to 60BIn one embodiment, at least a portion of the metal structural frame of support base 22 is formed from aluminum. For example, at least one of rigid frame 80 of second base component 78 and spin carriage 92 of third base component 86 can be formed from aluminum. However, it should be understood that while a portion of the structural frame of support base 22 can be formed from aluminum, another portion of the structural frame can be formed from a different material, such as steel. In the non-limiting embodiment shown in the figures, both rigid frame 80 and spin carriage 92 are formed from a first material, such as aluminum. In such embodiments, one or more components disposed at the interface between rigid frame 80 and spin carriage 92 are formed from a second material, such as steel. As shown, bottom spin cover 99, which is disposed between rigid frame 80 and spin carriage 92, is formed from a steel material. Similarly, base anchor component 104, which is disposed near one end of rigid frame 80, and seat anchor component 108, which is disposed at a corresponding location of spin carriage 92, can be formed from a steel material. The use of this combination of materials can require additional bolting. However, it should be understood that embodiments in which the structural frame of support base 22 is formed from another material or another combination of materials including a metal alloy having sufficient strength for application are also within the scope of the present disclosure.

[0302] Headrest 46 of child seat 24 as described herein can be moved between a retracted position and an extended position relative to upright support surface 30 of child seat 24, allowing for adjustment based on the size of a child positioned within child seat 24. A locking mechanism 600 operable to selectively lock headrest 46 in a position relative to child seat 24 generally includes a component associated with headrest 46 and receivable within one of a plurality of openings of a slot 602 formed in a channel 604 at or adjacent to upright support surface 30. In one embodiment, a portion of spin carriage 92 forms channel 604 including a plurality of slots 602 that define respective positions of headrest 46.

[0303] In embodiments in which spin carriage 92 is formed from an aluminum material, existing locking mechanisms can not be suitable for interaction with the aluminum components. In the non-limiting embodiment shown, locking mechanism 600 includes a first lock component 610 operably coupled to a second lock component 612. First lock component 610 can be moved relative to headrest 46 between a locked position Figure 62A , 62B in which first lock component 610 is engaged with slot 602 Figure 63B and 64BThe second lock component 612 can also be movable relative to the headrest 46. For example, the second lock component 612 can rotate about an axis between a disengaged position and an engaged position. In the illustrated non-limiting embodiment, the type and / or direction of movement of the second lock component 612 is different than the type and / or direction of movement of the first lock component 610. As shown, the axis of rotation of the second lock component 612 is arranged at a non-parallel angle to the axis of rotation of the first lock component 610. For example, the axes can be perpendicular to one another. However, any suitable configuration of the first lock component 610 and the second lock component 612 is within the scope of the present disclosure. A biasing mechanism 614, such as a torsion or spring, can be operably coupled to the first lock component 610 and can bias the first lock component 610 into engagement with the adjacent slot 602.

[0304] The lock mechanism 600 can be part of an actuation mechanism 620 associated with movement of the headrest 46. In one embodiment, the actuation mechanism 620 includes at least one link component 622. While only a single link component 622 is shown in the figures, it should be understood that in some embodiments, the actuation mechanism 620 can include multiple link components 622, such as a link component associated with each passage 604 of the slot 602 and corresponding lock mechanism 600. In the illustrated non-limiting embodiment, a portion of the second lock component 612 can be received within an opening 624 formed in the link component 622 when the actuation mechanism 620 is not actuated.

[0305] The actuation mechanism 620 additionally includes an actuator 626, such as a handle, arranged on the exterior of the headrest 46 for access by a user. In the illustrated non-limiting embodiment, the actuator 626 is disposed at or near the top of the headrest 46. The at least one link component 622 is operably coupled to the actuator 626. For example, a first end (not shown) of each link component 622 can be connected to the actuator 626, or in some embodiments integrally formed with the actuator.

[0306] The first lock component 610 disengages from the corresponding slot 602 in response to operation of the actuator 626, for example via application of a force to the actuator 626. Once disengaged, the headrest 46 is movable relative to the child seat 24. When a user applies a force to the actuator 626, the force is transmitted to the at least one link component 622, causing the at least one link component 622 to translate relative to the headrest 46. As the link component 622 translates, a surface of the link component 622 engages the second lock component 612 and applies a force to the second lock component, causing the second lock component 612 to rotate about its axis toward the first lock component 610. In its rotation, the second lock component 612 engages a portion of the first lock component 610. The force transmitted by the second lock component 612 to the first lock component 610 resists the biasing force of the biasing mechanism 614, in turn causing the first lock component 610 to rotate out of engagement with the slot 602.

[0307] When the actuator 626 is released, the biasing force of the biasing mechanism 614 will cause the first lock component 610 to rotate into engagement with the corresponding slot 602. Rotation of the first lock component 610 will drive a similar rotation of the second lock component 612. In its rotation about its axis, the second lock component 612 will apply a force to a corresponding portion of the link component 622, causing the link component 622 to translate downwardly such that the second lock component 612 is received within the opening 624 of the link component 622.

[0308] Yet another embodiment of a headrest locking mechanism 600 associated with a headrest 46 is shown in Figures 65 to 69B . As shown, the locking mechanism 600 includes a single lock component 640 having a first or ramp engagement component 642 and a second or slot engagement component 644. The lock component 640 can be disposed in direct contact with a portion of a link component 646. In the non-limiting embodiment shown, the link component 646 includes an opening 648 and a ramp surface 650 extending from the opening 648. It should be appreciated, however, that embodiments in which the link component 646 does not include an opening 648 are within the scope of the present disclosure. A biasing mechanism 652 is operably coupled to the lock component 640 to bias the slot engagement component 644 into and out of engagement with a slot associated with a position of the headrest 46, such as the slot 602 (see Figures 69A to 69B ).

[0309] As previously described, the link member 646 can be operatively coupled to a user-accessible actuator 654, and in some embodiments is integrally formed with said actuator. In response to the application of a force to the actuator 654, the link member 646 translates relative to the headrest 46. During this translation, the ramp engagement member 642 slides along the ramp surface 650. As the slope of the ramp surface 650 increases, this engagement causes the locking member 640 to pivot about its longitudinal axis. This rotation of the locking member 640 resists the biasing force of the biasing mechanism 652 and moves the slot engagement member 644 out of the corresponding slot 602 ( Figure 67B , 68B (69B). For example Figures 68A to 69B As shown, the disengagement slot 656 may be formed in a portion of the headrest 46 aligned with the slot engagement member, such as the headrest housing 47. Thus, when the slot engagement member 644 rotates out and engages with the slot 602 associated with the child seat, the slot engagement member 644 is housed within the disengagement slot 656 of the headrest 46. When the actuator 654 is released, gravity may cause the link member 646 to move downward relative to the headrest 46, causing the ramp surface 650 to disengage from the ramp engagement surface. Furthermore, the biasing force of the biasing mechanism 652 will cause the locking member 640 to rotate back to engage with the corresponding slot 602 to lock the headrest in a position into the slot. However, it should be understood that in some embodiments, the biasing force of the biasing mechanism 652 may be sufficient to move the ramp surface 650 away from the ramp engagement member 642 and cause the locking member 640 to rotate about its axis.
