[Modes for carrying out the invention]

[0118] A detailed description of one or more embodiments of the disclosed apparatus and method is provided herein with reference to the figures, as illustrative and not limiting.

[0119] Next, various examples of the child safety seat system 20 are shown with reference to the figures. 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 the vehicle seat 10 (see Figures 1 and 20) via a latch or anchoring mechanism, etc., which is not shown in the figures. This latch or anchoring system, which is often used, is sometimes referred to as a “lower anchor and tether for children” (e.g., a LATCH system). Alternatively, or in addition to that, the support base 22 may be removably secured to the vehicle seat 10 via a vehicle belt associated with the vehicle seat 10.

[0120] The child safety seat system 20 further includes a child safety seat 24 associated with a support base 22. In one embodiment, the child safety seat 24 is detachably coupled to the support base 22, thereby allowing the child safety seat 24 to be separated from the support base 22. Alternatively, as will be described in more detail later, the support base 22 and at least a portion of the child safety seat 24 may be permanently connected or attached together. As used herein, the term “permanently connected” identifies embodiments in which the child safety seat 24 or any portion thereof is not intended to be disassembled from the support base 22 by the user.

[0121] The child safety seat 24 includes a seat back portion 26 and a seat pan portion 28 positioned diagonally to the seat back portion 26. The seat pan portion 28 may, but is not required, be configured to be detachably coupled to the seat back portion 26. In the illustrated non-limiting embodiment, the seat back portion 26 includes a seat back having an upright support surface 30. The upright support surface 30 faces generally forward and extends from a first end or top 32 of the seat back portion 26 to a second opposite end or bottom 34 of the seat back portion 26. A first upright side member 36 may be positioned on the first side 38 of the upright support surface 30, and a second upright side member 40 may be positioned on the second opposite side 42 of the upright support surface 30. Thus, the first upright side member 36 and the second upright side member 40 form the left and right sides of the seat back portion 26, respectively. As illustrated, the first upright side member 36 and the second upright side member 40 extend forward from the upright support surface 30. The first upright side member 36 and the second upright side member 40 may extend approximately perpendicular to the upright support surface 30, or they may extend from it at a different angle (for example, an angle greater than 90°). Thus, the upright support surface 30 and the first upright side member 36 and the second upright side member 40 define a backrest area or upright support cavity in which the child's upper body is accommodated.

[0122] The upright side members 36, 40 can facilitate the correct positioning of the vehicle belt during one or more driving modes when the child safety seat 24 is installed in the vehicle. In some embodiments, though not shown, an opening is formed within each upright side member 36, 40. The opening may be configured to accommodate a vehicle belt (not shown) to secure the child safety seat 24 to the vehicle seat 10 in a forward-facing configuration, or to secure the upper body of a child located within the cavity.

[0123] In the non-limiting embodiments shown in Figures 21A to 23, the seat back portion 26 is an assembly including a seat back 27 comprising an upright support surface 30 and a first upright side member 36 and a second upright side member 40 extending diagonally therefrom, as described above. A separate back cover or seat back shell 29 may be positioned in contact with the rearward-facing surface 31 of the seat back 27. In the illustrated non-limiting embodiments, the seat back shell 29 has a size and shape complementary to the seat back 27, and the seat back shell 29 overlaps the entire rearward-facing surface 31 of the seat back 27. However, embodiments in which the seat back shell 29 covers only a portion of the rearward-facing surface 31 of the seat back 27 are also within the scope of the disclosure. In such embodiments, the seat back shell 29 may be formed from a first material (e.g., plastic or composite material), and the seat back 27 may be formed from a different second material (e.g., polystyrene or high-density foam). Furthermore, soft goods (not shown) can be attached to the inward-facing surface of the seat back 27 to provide cushioning for children positioned within the backrest area.

[0124] Referring further to Figures 21A to 23, in the illustrated non-limiting embodiment, the seat back panel 33 is mounted in a configuration that overlaps with the upright support surface 30 of the seat back 27. The seat back panel 33 may have a configuration complementary to the upright support surface 30. As shown, the seat back panel 33 is substantially rectangular and includes a length approximately equal to the distance between the top 32 and bottom 34 of the upright support surface 30, and a width approximately equal to the distance between the first side surface 38 and the second side surface 42 of the upright support surface 30. In other embodiments, the seat back panel 33 may cover only a portion of the upright support surface 30, or it may extend beyond the upright support surface 30 (for example, in a configuration that overlaps with one or both of the first upright side member 36 and the second upright side member 40).

[0125] Regardless of the configuration of the seatback portion 26, in non-limiting embodiments, one or more bumpers or side impact pods 37 designed to absorb force in the event of an accident or collision may be positioned on the outer surface 35 of the seatback portion 26. While Figures 21A to 23 show a single impact pod 37, it should be understood that embodiments having multiple impact pods 37 are also within the scope of this disclosure. As illustrated, at least one impact pod 37 may be positioned near the top 32 of the seatback portion 26. In one embodiment, at least one impact pod 37 may be positioned vertically above the support base 22 (for example, when the child safety seat 24 is in a forward-facing configuration). Furthermore, when the child safety seat system 20 is installed around the vehicle seat 10, at least one impact pod is not positioned to be in contact with the vehicle seat 10. However, embodiments including impact pods 37 positioned elsewhere, either alternatively or additionally, are also intended herein. In the illustrated, non-limiting embodiments, the impact pod 37 is positioned substantially in the center and extends around or wraps around the outer surface 35 toward at least one, in some embodiments both, of the first upright side member 36 and the second upright side member 40. Thus, at least one impact pod 37 can substantially surround the rear of the seat back portion 26. However, it should be understood that embodiments in which one or more impact pads 37 are positioned only in the center of the seat back portion (e.g., substantially aligned with the upright support surface 30) or only on the sides of the outer surface (e.g., aligned with one of the upright side members 36, 40) are also intended herein.

[0126] In the illustrated, non-limiting embodiments, the seatback portion 26 of the child safety seat 24 includes a headrest 46. The headrest 46 may be attached to the seatback portion 26, integrated with the seatback portion 26, or detachably coupled to the seatback portion 26. The headrest 46 may be stationary or, in some embodiments, may be configured to move relative to the upright support surface 30. For example, the headrest 46 may be configured to move relative to the upright support surface 30 between a retracted position and an extended position, thereby allowing adjustment based on the size of the child positioned in the child safety seat 24. However, it should be understood that embodiments in which the seatback portion 26 does not include a headrest 46 are also intended herein.

[0127] Referring to Figures 5, 6, and 24A-24C, in one embodiment the headrest 46 includes a main body (specified as 300) having a head support surface 302. A first head side member 304 may be positioned on the first side 306 of the head support surface 302, and a second head side member 308 may be positioned on the second opposite side 310 of the head support surface 302. The first head side member 304 and the second head side member 308 form the left and right sides of the headrest 46, respectively. The first head side member 304 and the second head side member 308 extend forward from the head support surface 302. Thus, the head support surface 302, the first head side member 304, and the second head side member 308 define a headrest area or cavity in which the head of a child located within the child safety seat 24 is accommodated. The first head side member 304 and the second head side member 308 may extend substantially perpendicular to the head support surface 302, or from there at a different angle (for example, an angle greater than 90°). At least one angle of the first head side member 304 and the second head side member 308 with respect to the head support surface 302 may be equal to or different from the corresponding angle of the first upright side member 36 and the second upright side member 40 with respect to the upright support surface 30.

[0128] In one embodiment, as shown in Figures 24A to 24C, the main body of the headrest 46 is an assembly including a first portion 312 having a head support surface 302 and a first head side member 304 and a second head side member 308 extending diagonally therefrom as described. A second portion 314, including a headrest cover or panel, can be positioned in contact with the rearward-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, and the second portion 314 substantially overlaps the entire rearward-facing surface of the first portion 312. In such an embodiment, the second portion 314 may be a structural shell formed from a first material (e.g., plastic), and the first portion 312 may be formed from a different second material (e.g., polystyrene or high-density foam). Soft goods (not shown) may be placed on one or more surfaces of the first portion 312 facing the headrest area to provide cushioning to a child placed in the child safety seat 24. In embodiments, a channel 316 is formed between the first portion 312 and the second portion 314, and a portion of the soft goods is placed within the channel 316 to connect the soft goods to the headrest 46. However, any suitable means for attaching the soft goods to the headrest 46 are intended herein.

[0129] The headrest 46 may include at least one shoulder belt guide 320 having an opening 322 therein for receiving a vehicle belt. The shoulder belt guide 320 may be formed integrally with the headrest body or may be a separate component attached thereto. As shown in Figures 24A to 24C, at least one shoulder belt guide 320 may be aligned with a portion of the main body 300 and mounted as an extension thereof. For example, at least one shoulder belt guide 320 may be positioned on the bottom surface of one or both of the first head side member 304 and the second head side member 308. The shoulder belt guide 320 may have a shape complementary to an adjacent portion of the main body 300, so that the shoulder belt guide is coplanar with the main body and defines a portion of the contour of the headrest 46. At least one shoulder belt guide 320 may be permanently attached to the main body 300 or may be detachably coupled thereto. In the illustrated non-limiting embodiments, the shoulder belt guide 320 is attached to the main body 300 (for example, between the first portion 312 and the second portion 314) using, for example, one or more fasteners. However, it should be understood that any suitable means for detachably connecting the shoulder belt guide 320 to any location on the main body 300 of the headrest 46 is within the scope of this disclosure.

[0130] The seat pan portion 28 of the child safety seat 24 may include a seat support surface 50 that generally faces upward. The seat support surface 50 extends from a first end or front portion 52 to a second end or rear portion 54 of the seat pan portion 28. A first seat side member 56 may be positioned on the first side portion 58 of the seat support surface 50, and a second seat side member 60 may be positioned on the second opposite side portion 62 of the seat support surface 50. The first seat side member 56 and the second seat side member 60 extend upward from the left and right sides of the seat portion. Together, the seat support surface 50, the first seat side member 56 and the second seat side member 60 define an area in which at least a portion of the child's lower body can be accommodated.

[0131] As shown in the diagram, the sheet side members 56 and 60 extend diagonally from the sheet support surface 50. The angle of the first sheet side member 56 with respect to the sheet support surface 50 may be the same as the angle of the first upright side member 36 with respect to the upright support surface 30, but is not necessarily required. Similarly, the angle of the second sheet side member 60 with respect to the sheet support surface 50 may be the same as the angle of the second upright side member 40 with respect to the upright support surface 30, but is not necessarily required.

[0132] In the illustrated non-limiting embodiment, a slot 66 is formed in each seat side member 56, 60. The slot 66 is configured to function as a lap belt guide during at least one mode of use of the child safety seat 24. In some operating modes of the child safety seat 24, the slot 66 may be configured to accommodate and position a lap belt portion of a vehicle restraint or a separate restraint belt for securing a child within the child safety seat 24. The rotational configuration and / or tilt of the child safety seat 24 can be adjusted when the child safety seat 24 is connected to the support base 22, as will be described in more detail later.

[0133] The child safety seat 24 generally includes a first booster portion and a second booster portion, and in embodiments, the seat back portion 26 may be considered the first booster portion and the seat pan portion 28 may be considered the second booster portion. However, embodiments in which the seat pan portion 28 is the first booster portion and the seat back portion 26 is the second booster portion are also intended herein. The first booster portion may, but is not required, be configured to be detachably coupled to the second booster portion. In the non-limiting embodiments shown in Figures 20A and 20B, the seat back portion 26 includes at least one seat back fitting feature 67, and the seat pan portion 28 includes at least one seat pan fitting feature 68 that can selectively fit with the corresponding seat back fitting feature. As illustrated, the seat back fitting feature 67 may be a projection extending from the vicinity of the second end 34, and the seat pan fitting feature 68 may be a corresponding recess or opening formed on the surface of the seat pan portion 28 and aligned with the projection. Thus, the projection is accommodable within the recess, connecting the seat back portion 26 to the seat pan portion 28. However, embodiments in which the seat pan fitting feature 68 is a projection and the seat back fitting feature 67 is a recess are also intended herein. Furthermore, other suitable mechanisms for removably connecting the seat back portion 26 to the seat pan portion 28 are also within the scope of this disclosure.

[0134] The support base 22 for mounting the child safety seat 24 includes a base body having a base seat portion 70 and a base back portion 72 (see Figure 1). Suitable materials for fabricating the base body include, but are not limited to, rigid plastics or composite materials. The base seat portion 70 and the base back portion 72 may be formed as a single body or may be formed by separate components that are detachably or permanently connected to each other.

[0135] Referring next to Figure 2, in 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 (e.g., 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 portion, and / or the second base member 78 may include a rigid frame 80 at least partially housed within a structural shell 82. At least a portion of the second base member 78 may be positioned in a configuration that overlaps with the top surface 84 of the first base member 74. In the illustrated non-limiting embodiment, the first base member 74 is located only on the base seat portion 70 of the support base 22, and the second base member 78 forms part of both the base back portion 72 and the base seat portion 70. However, embodiments in which the first base member 74 forms part of both the base back portion 72 and the base seat portion 70 are also intended herein. Referring to the figure, in this embodiment, the support base 22 includes a third base member 86 (for example, a spin member) positioned in an overlapping arrangement with the second base member 78. The third base member 86 includes a base member seat portion 88 positioned on the base seat portion 70 of the support base 22, and may include a base member back portion 90 extending diagonally from the base member seat portion 88. As will be described in more detail later, at least a portion of the child safety seat 24 is detachably coupled to the third base member 86 of the support base 22.

[0136] A third base member 86, and therefore any portion of the child safety seat 24 coupled to the third base member 86, may be rotatable about an axis relative to the first base member 74 and the second base member 78. In embodiments, the third base member 86 includes a spin carriage 92. The spin carriage 92 may have various configurations as shown in Figures 2, 3, 25, and 26. In the non-limiting embodiments shown in Figures 2 and 3, the spin carriage 92 is at least partially housed within a structural shell or body 94. However, embodiments without a body 94 are also intended herein. For example, in embodiments shown in Figures 25 to 27, the base member back portion 90 and the distal end of the spin carriage 92 may be positioned between the seat back panel 33 and the seat back (e.g., an upright support surface 30). The seat back panel 33 may include a projection or tab 96 which is insertable into a corresponding recess or opening (not shown) formed in the base member seat portion 88, and which connects the third base member to the seat back portion 26.

[0137] Referring to Figure 70, the storage compartment 700 may be formed in part of the support base 22 (e.g., the base back portion 72). Although the storage compartment 700 is generally shown to be formed only on the second base member 78, embodiments in which the storage compartment 700 is formed only on the first base member 74, or by a combination of the first base member 74 and the second base member 78, are also within the scope of this disclosure. In embodiments, one or more latches (not shown) (e.g., a LATCH system) for attaching the child seat system 20 to a vehicle seat may be held within the storage compartment 700. As shown, the cover 702 is movable relative to the support base 22 between an open position and a closed position (not shown) to selectively seal the storage compartment 700. In embodiments, the cover 702 is removable from the support base 22. However, in other embodiments, the cover 702 may be movably coupled (for example, swivelly or hinged) to the support base 22 so that the cover 702 remains attached to the support base when the cover 504 is in both the open and closed positions.

[0138] The second base member 78 in the base seat portion 70 may include a contour or opening 97 (see Figure 29), and a portion of the third base member 86 may be housed within the opening 97. In the embodiments shown in Figures 3, 4, and 25-27, near the bottom of the third base member 86, the spin carriage 92 includes a circular flange 98 (for example, its edges are rolled or otherwise shaped to form a sheet anchor or lip 100). A portion of the second base member 78 (for example, a rigid frame 80) may include one or more hooks or anchors 102 (see Figures 3 and 25) having a curvature configured to engage with the lip 100. In some embodiments, such as those shown in Figures 22 and 27, a bottom spin cover 99 may be positioned directly below the circular flange 98 in the vertical direction. In such embodiments, the bottom spin cover 99 may, but is not required, be mounted on the circular flange 98.

[0139] In the embodiment, the third base member 86 is rotatable around an axis between multiple configurations with respect to the first base member 74 and the second base member 78 of the support base 22. In the embodiment, the third base member 86 (and therefore the child safety seat 24 connectable to the third base member 86) is rotatable with respect to both the first base member 74 and the second base member 78 of the support base 22. For example, the fitting between the lip 100 and the corresponding hook 102 formed on the second base member 78 can define the rotational path of the third base member 86 with respect to the first base member 74 and the second base member 78, and therefore the rotational path of the child safety seat 24 with respect to the support base 22. As shown in Figures 4, 16, and 17, the third base member 86 (and therefore the child safety seat 24 connectable to the third base member 86) is rotatable between a first rotational configuration, for example, a configuration in which the child safety seat 24 is in a forward-facing position (Figures 1 and 3), and a second rotational configuration, for example, a configuration in which the child safety seat 24 is in a rearward-facing position (Figures 4 and 16). However, it should be understood that embodiments in which the child safety seat 24 is positionable in one or more additional configurations between the first and second rotational configurations are also within the scope of this disclosure.

[0140] The spin lock 330 can be used to selectively lock the rotation of the third base member 86 (and thus the child safety seat 24 coupled to the third base member 86) in one of several configurations relative to the support base 22. An example of the spin lock 330 is shown in more detail with reference to Figures 28A and 28B. As shown, the spin lock 330 is located within a portion of the second base member 78 in the base seat portion 70 of the support base 22. Referring to the illustrated non-limiting embodiment, the spin lock 330 includes a centrally located connecting link 332 that is rotatable about axis X. In the embodiment, the connecting link 332 may be appropriately attached to the support base 22 via bolts or other suitable fasteners. As shown, two end segments 334 may extend outward from the connecting link 332 (for example, located on either side of the connecting link 332 with respect to the axis of rotation). A number of locking pins 336 (for example, two locking pins) are connected to the connecting link 332. For example, the first end 338 of each locking pin 336 is connected to the respective end segment 334 of the connecting link 332. As shown in the illustration, the locking pins 336 may extend in the opposite direction from the connecting link 332.

[0141] The locking pin 336 can be changed between a first locked position (Figure 28A) in which the child safety seat 24 is not rotatable relative to the support base 22, and a second unlocked position (Figure 28B) in which the child safety seat 24 is freely rotatable relative to the support base 22. When each of the locking pins 336 (and thus the spin locks 330) is in the locked position, the second opposite end 340 of the locking pin 336 is housed in a corresponding locking portion 342 (e.g., a groove or opening) formed in a part of the support base 22. When the locking pin 336 (and thus the spin locks 330) is in the second unlocked position, the second end 340 of the locking pin 336 moves away from the locking portion 342, allowing the child safety seat 24 to rotate relative to the second base member 78. In the illustrated non-limiting embodiment, a plurality of locking portions 342 are formed in the second base member 78. However, embodiments in which multiple locking portions 342 are formed on the first base member 74 or another suitable component are also intended herein. In these embodiments, a biasing member (not shown) (e.g., a torsion spring) is operably coupled to the connecting link 332, biasing the connecting link 332 (and thus the locking pin 336) to a first locked position.

[0142] Referring further to Figures 29-32B, and continuing to Figures 28A and 28B, at least one actuator 350 is operably coupled to at least one of the lock pins 336. In the illustrated non-limiting embodiments, multiple actuators are operably coupled to the spinlock 330. As illustrated, a first actuator 350a is operably coupled to a first lock pin 336, and a second actuator 350b is operably coupled to a second lock pin 336. Each actuator 350a, 350b may be independently or individually operated to change the lock pin 336 from the locked position to the unlocked position. Alternatively, or in addition to this, the first actuator 350a and the second actuator 350b may be operated simultaneously to change the lock pin 336 from the locked position to the unlocked position.

[0143] In the illustrated non-limiting embodiments, several actuators 350a, 350b are substantially identical and include handles 352 positioned on the outer surface of the child safety seat 24. The handles 352 may be directly or indirectly connected to a locking pin 336. As illustrated, each handle 352 is operably coupled to the corresponding locking pin by a wire, cable, or other suitable tension member 354. The handles 352 may be part of or integrated with a drive member 356 that is swivelably mounted on the child safety seat 24. In such embodiments, the drive member 356 is positioned such that the handles 352 extend through an opening (e.g., a seat back shell 29) and are exposed to the outside of the child safety seat 24. However, embodiments in which the handles 352 are separate from the drive member 356 and operably coupled to the drive member 356 are also intended herein. A fitting link 360 connected to a tension member 354 may be movably coupled to the drive member 356.

[0144] In the illustrated non-limiting embodiment, an angled slot 362 is formed in the drive member 356, and a pin 364 (for example, near its end) extending through an opening 366 formed in the mating link 360 is also housed in the slot 362. The spin 364 is configured to move within the slot 362 in response to the rotation of the drive member 356. Due to the angled configuration of the slot 362, this movement of the pin 364 and the mating link 360 relative to the drive member 356 applies a force to the tension member 354. As shown in Figure 31, the drive member 356, the mating link 360, and a portion of the tension member 354 may be embedded within the seat back portion 26 (for example, between the seat back 27 and the seat back shell 29).

[0145] To operate actuator 350a and unlock spin lock 330, the user applies a force F1 (Figure 32A) to handle 352. In one embodiment, the user is configured to rotate handle 352 forward. However, embodiments in which handle 352 is moved in a different direction (e.g., pulled, pushed inward, or pulled outward) are also within the scope of the disclosure. This movement of the handle causes the drive member 356 to rotate about its axis, thereby causing the pin 364 of the mating link 360 to move upward in the slot 362 (see Figure 32B). Thus, in response to the force applied to handle 352, a force (in the direction opposite to the biasing of the biasing member) is applied to the corresponding lock pin 336. The movement or translation of the first lock pin 336 causes the connecting link 332 to rotate about its axis X opposite to the biasing of the biasing member. Since the second locking pin 336 is also connected to the connecting link 332, rotating the connecting link 332 via the first locking pin 336 causes the second locking pin 336 to move inward as well. Through this inward movement, the second ends 340 of both locking pins 336 are disengaged from the corresponding locking portions 342 of the support base 22. With the actuators 350a and 350b in operation and the locking pins 336 disengaged from the locking portions 342, the user can further rotate the child safety seat 24 relative to the support base 22 to achieve the desired rotational configuration.

[0146] Once the child safety seat 24 reaches the desired rotation configuration, the user releases the actuators 350a and 350b. Upon release of the actuators 350a and 350b, the biasing force of the biasing member causes the connecting link 332 to rotate, and the locking pin 336 moves outward (e.g., translates) to engage with the corresponding locking portion 342 associated with the rotation configuration of the child safety seat 24. This force, applied to the tensioning member 354 via this outward movement, causes the engaging link 360 to move relative to the slot 362, and the drive member 356 rotates around its axis to return to the non-operating position. The spin lock 330 illustrated and described herein is intended only as an example, and it should be understood that any suitable configuration is within the scope of this disclosure.

[0147] Another embodiment of the spinlock 400 is shown in Figures 38 to 40B. Similar to the previous embodiment, the spinlock 400 includes a central portion 402 that is movably mounted on the child seat 24. In the illustrated non-limiting embodiment, the central portion 402 is movable relative to the child seat 24. It should be understood that the child seat 24 is rotatably coupled to the support base 22 via bolts or other suitable fasteners (403) in positions other than the spinlock 400.

[0148] As illustrated, the central portion 402 may include at least one mating slot 404 (for example, a pair of mating slots). At least one locking pin 406 may be fixed to the central portion 402. In the illustrated non-limiting embodiment, a pair of locking pins 406 are movably coupled to a pair of mating slots 404, respectively. As illustrated, the locking pins 406 may extend outward from the central portion 402 in opposite directions.

[0149] The locking pin 406 can be moved between a first locked position (Figure 39A) in which the child safety seat 24 is not rotatable relative to the support base 22, and a second unlocked position (Figure 39B) in which the child safety seat 24 is freely rotatable relative to the support base 22. When each of the locking pins 406 (and thus the spin lock 400) is in the locked position, the distal end 408 of the locking pin 406 is housed within a corresponding locking portion (not shown) formed in part of the support base 22. When the locking pin 406 (and thus the spin lock 400) is in the second unlocked position, the distal end 408 of the locking pin 406 moves away from the locking portion, allowing the child safety seat 24 to rotate relative to the support base 22.

[0150] An actuator 410 (Figure 40), operably coupled to the central portion 402, is operable to change the spin lock 400 between a locked position and an unlocked position. In a non-limiting embodiment, the actuator is shown to be located on 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 located at a different position around the child seat 24 or at a different position around the support base 22 are also intended herein. When operating, the actuator 410 applies force to the central portion 402. As shown, the mating slot 404 formed in the central portion 402 is positioned at an angle nonparallel to the direction of movement of the central portion 402. Thus, the locking pin 406 is configured to move inward as the locking pin 406 moves within the mating slot 404 in response to the force applied to the central portion 402 by the actuator 410.

[0151] Another embodiment of the spin lock 800 is shown in Figures 71A to 72. Similar to the previous embodiment, the spin lock 800 includes a centrally located connecting link 802 that is rotatable about an axis X. The connecting link 802 may be attached to a support base 22 via bolts or other suitable fasteners. As shown, two end segments 804 may extend outward from the connecting link 802 (for example, they may be located on either side of the connecting link 802 with respect to the axis of rotation X). A number of lock pins 806, 808 may be connected to the connecting link 802. Unlike the above embodiment in which two lock pins may be substantially identical, in the illustrated non-limiting embodiment, the first lock pin 806 has a first configuration and the second lock 808 has a second configuration different from the first configuration. As shown, the first lock pin 806 may be substantially rectangular in shape, thereby the first end 810 and the second end 812 of the first lock pin 808 are coaxial. The first end 810 of the first locking pin 806 may be connected to the end segment 804 of the connecting link 802, and the second end 812 of the first locking pin 808 may extend outward toward the outer circumference of the support base 22. The second locking pin 808 may include a first portion 814 having a substantially curved or arc-shaped contour, and a second portion 816 having a rectangular configuration that is coupled to or integrally formed with the first portion 816. The first end 818 of the second locking pin 808 (e.g., formed on the first working portion 814) may be connected to the end segment 804 of the connecting link 802, and the second end 820 of the second locking pin 808 (located on the second portion 816) may extend radially outward from the connecting link 802. As illustrated, the first locking pin 806 and the second portion 816 of the second locking pin 808 may be coaxial. Furthermore, the axes of the first locking pin 806 and the second portion 816 of the second locking pin 808 may be spaced apart from or offset from the rotation axis X of the connecting link 802, and therefore do not intersect with the rotation axis X of the connecting link 802.

[0152] The first locking pin 806 and the second locking pin 808 are movable between a first locked position (Figure 71A) in which the child safety seat 24 is not rotatable relative to the support base 22, and a second unlocked position (Figure 71B) in which the child safety seat 24 is freely rotatable relative to the support base 22. When in the locked position, the second ends 812 and 820 of the locking pins 806 and 808 are housed within corresponding locking portions (not shown) formed on a part of the support base 22. When the locking pins 806 and 808 (and thus the spin lock 800) are in the second unlocked position, the second ends 812 and 820 of the locking pins 806 and 808 move away from the locking portions, allowing the child safety seat 24 to rotate relative to the support base 22.

[0153] In the illustrated non-limiting embodiment, slots 822, 824 are formed in a portion of the first locking pin 806 and a portion of the second locking pin 808 (for example, a second portion 816), and pins or fasteners 826, 828 are positioned within their respective slots 822, 824. The mating between the pins 826, 828 and the corresponding slots 822, 824 defines the respective movement paths of the first locking pin 806 and the second locking pin 808. As the spin lock 800 changes between the locked and unlocked positions, each slot 822, 824 moves relative to its respective pin 826, 828. When the spinlock 800 is in a locked configuration, pins 826 and 828 may be located adjacent to the first ends of slots 822 and 824 (for example, the ends of slots 822 and 824 closest to the connecting link 802), and when the spinlock 800 is in an unlocked configuration, pins 826 and 828 may be located adjacent to the second opposite ends of slots 822 and 824.

[0154] At least one biasing mechanism is operably coupled to the spin lock 800 and biases the first lock pin 806 and the second lock pin 808 radially outward toward the locked position. In one embodiment, the biasing mechanism is coupled to a connecting link 802. However, in another embodiment, as shown in the figure, each biasing member 830, 832 (e.g., a coil spring) is operably coupled to the first lock pin 806 and the second lock pin 808, respectively, and is operable to bias the first lock pin 806 and the second lock pin 808 toward the first locked position.

[0155] An actuator schematically shown in Figure 72 (840) is operably coupled to the spin lock 800. In the illustrated non-limiting embodiment, the connecting 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. Applying force to the actuator 840 is operable to rotate the connecting link 802 about its axis X. This rotation applies force to the first lock pin 806 and the second lock pin 808, moving the lock pins 806, 808 from the locked position to the unlocked position. While the lock pins 806, 808 are held in the unlocked position by applying force to the actuator 840, the second base member 78 is movable relative to the first base member 74. Furthermore, the actuator 840 can be biased to the normal position in response to the removal of the force applied to the actuator 840. The actuator 840 may be positioned at any suitable location around the child safety seat 24 (for example, on the outer surface of the upright side member). Alternatively, the actuator 840 may be positioned on a support base (for example, the first base member 76 or the second base member 78).

[0156] At least one base anchor member 104 may be fixedly connected to a portion of the second base member 78. For example, the base anchor member 104 may be part of the frame 80 and may extend through an opening formed in the structural shell 82 (see Figure 2). In the illustrated non-limiting embodiment, a base anchor member 104 is included that is positioned near the distal end 106 of the second base member 78 in the base back portion 72 of the support base 22, but it should be understood that the base anchor member 104 may be positioned in any suitable location. The base anchor member 104 is connectable to a corresponding seat anchor member 108. In the embodiment, the seat anchor member 108 is located on the third base member 86. For example, the seat anchor member 108 may be located on the base member back portion 90, thereby allowing the base anchor member 104 to be connectable to the base member back portion 90 when the child safety seat 24 is connected to the third base member 86 in a forward-facing configuration. In the non-limiting embodiments shown, the seat anchor member 108 includes a flange or groove with a complementary contour to the base anchor member 104. In other embodiments, the seat anchor member 108 may be positioned on the child safety seat 24. For example, in the non-limiting embodiments of Figures 21B and 23, the seat anchor member 108 protrudes from the seat back portion 26 (for example, from its outer surface 35).

[0157] As will be explained in more detail later, the base anchor member 104 may also be connectable to the seat anchor member 108, regardless of the angle of inclination of the child safety seat 24 relative to the support base 22. This connection between the base anchor member 104 and the seat anchor member 108 stabilizes the seat back portion 26 of the child safety seat 24. In such embodiments, the base anchor member 104 may not be connectable to the seat anchor member 108 when the child safety seat 24 is in a rearward-facing configuration. However, it should be understood that the base anchor member 104 may be suitable for use with a third base member 86 and / or a seat anchor member 108 positioned at any location around the child safety seat 24.

[0158] Alternatively, or in addition to the above, the child safety seat 24 is movable relative to at least a portion of the support base 22 when coupled to the support base 22, allowing adjustment of the tilt of the child safety seat 24. In embodiments, a second base member 78 is movable (e.g., translatable) relative to the first base member 74 along an inclined path to control the tilt or recline of the child safety seat 24. Since a third base member 86 is coupled to the second base member 78, the third base member 86 and the child safety seat 24 to which it can be connected are movable simultaneously with the second base member 78 between a first position (e.g., related to the upright position of the child safety seat 24) and a second position (e.g., related to the reclined position of the child safety seat 24). However, it should be understood that both the first and second reclining positions can be inclined positions, and the degree of inclination of the positions can vary. Furthermore, embodiments in which the child safety seat 24 may be positioned in any of a plurality of reclining positions between the upright position and the reclined position are also intended herein.

[0159] Furthermore, the support base 22 may include a reclining lock mechanism that can operate to selectively lock a second base member 78 (and thus the child safety seat 24 coupled to it via a third base member 86) at one of a plurality of positions along the inclined path. An example of the reclining lock mechanism 420 is shown in Figures 41 to 44B. As illustrated, the reclining lock mechanism 420 includes a centrally located pivot link 422 that is rotatable about an axis. As illustrated, two end segments 424 may extend outward from the pivot link 422 (for example, they may be located on either side of the pivot link 422 with respect to its axis of rotation). At least one reclining pin 426 (for example, two reclining pins) is connected to the pivot link 422. As illustrated, the reclining pins 426 may extend in the opposite direction from the pivot link 422.

[0160] Multiple reclining pins can simultaneously change between a first locked position (Figures 42, 43A, and 44A) (where the second base member 78 is not movable relative to the first base member 74) and a second unlocked position (Figures 43B and 44B) (where the second base member 78 (and therefore the child seat 24 rotatably coupled to the second base member 78) is freely movable relative to the first base member 74, adjusting the inclination between the second base member 78 and the child seat 24). When each of the reclining pins 426 is in the locked position, the second end 428 of the reclining pin 426 is accommodated by a corresponding locking opening 430 formed in a part of the first base member 74 (for example, its side wall). When the reclining pin 426 is in the second unlocked position, the second end 428 of the reclining pin 426 moves away from or disengages from the locking opening 430, allowing the second base member 78 and the child seat 24 to be tilted or reclined.

[0161] In the embodiment, each biasing member 432 (e.g., a coil spring) is operably coupled to each of the reclining pins 426 and is operable to bias the reclining pins 426 to a first locked position. An actuator 434 is operably coupled to the reclining lock mechanism 420. In the illustrated non-limiting embodiment, the pivot link 422 includes a radially extending actuating tab 436, and the actuator 434 is coupled to the actuating tab 436 via a link mechanism or tension member 438. Applying force to the actuator 434 is operable to rotate the pivot link 422 about its axis. This rotation applies force to the reclining pins 426, moving them from the locked position to the unlocked position. While the reclining pins 426 are held in the unlocked position by applying force to the actuator 434, the second base member 78 is movable relative to the first base member 74. The actuator 434 can be biased to its normal position in response to the removal of a force applied to it. A biasing mechanism (not shown) may be directly connected to the actuator 434, or the biasing mechanism may be related to an intermediate component that can mate with the actuator 434 and transmit a biasing force to it, as shown in Figures 44A and 44B.

[0162] As shown in Figure 42, the first base member 74 includes a plurality of locking openings 430, each of which is associated with a different tilt or recline of the child seat 24. Thus, the second base member 78 is movable to a position configured such that the end 428 of the recline pin 426 is aligned with and engages with each of the locking openings 430. The recline locking mechanism 420 illustrated and described herein is intended only as an example, and it should be understood that any mechanism suitable for selectively locking and unlocking the child seat 24 and / or the second base member 78 with respect to movement relative to the first base member 74 for adjusting the tilt of the child seat 24 is within the scope of this disclosure. Furthermore, when the child seat is locked in any of the plurality of recline positions, the child safety seat 24 may be rotatable relative to the support base between a forward-facing configuration and a rearward-facing configuration.

[0163] Referring next to Figures 45 to 47, in the embodiment, the support base 22 includes a belt tensioner 450. In the illustrated non-limiting embodiment, an opening 452 is formed in the base back portion of the support base 22 (e.g., a second base member 78), and the belt tensioner 450 is accommodable within the opening 452. Since the contour of the belt tensioner 450 may be complementary to that of the opening 452, substantially the entire belt tensioner 450 is accommodable within the opening 452. The vehicle belt associated with the vehicle seat 10 is positionable along a belt accommodating path defined between the surface of the base back portion 72 of the support base 22 and the belt tensioner 450. In the embodiment, the belt tensioner 450 is selectively movable relative to the support base 22 and adjusts the tension applied to the vehicle belt 12 along the vehicle belt accommodating path. For example, the belt tensioner 450 may be configured to pivot about at least one axis between an open position (Figures 45 and 46) and a closed position (Figure 38) to selectively apply tension to the portion of the vehicle belt 12 sandwiched between the belt tensioner 450 and the opening 452, thereby connecting the support base 22 to the vehicle belt 12, thereby restricting the movement of the support base 22 relative to the vehicle seat 10.

[0164] A belt tensioner locking mechanism 470 can be used to hold the belt tensioner 450 in a closed position. As illustrated, a portion of the belt tensioner 450 (for example, near its uppermost end 456) includes a rigid shaft or pin 458. One or more slots 460 may be formed on the surface 462 of the belt tensioner 450 facing the opening 452, extending to the shaft 458 and defining a passage for accessing the shaft 458. At least one latch 472 is positioned within the opening 452, aligned with the slots 460 formed on the surface 462, and is connectable to the shaft 458. In one embodiment, each latch 472 includes a movable member 474 and a fixed member 476. When the latch 472 is open (Figure 46), the movable member 474 is positioned at an angle non-parallel to the fixed member 476. Therefore, the ends of the movable member 474 and the fixed member 476 are separated from each other, defining an opening for accommodating the shaft 458. When the latch 472 is closed (Figure 45), the movable member 474 rotates toward the fixed member 476. In the closed configuration, the movable member 474 may be oriented substantially parallel to the fixed member 476, and the distal ends of the movable member 474 and the fixed member 476 may overlap each other. Therefore, when closed, the opening 478 defined between the movable member 474 and the fixed member 476 is substantially closed, thereby locking the shaft 458 in place relative to the latch.

[0165] A biasing mechanism (not shown) may be associated with the movable member 474 of the clasp 472 and may be operable to bias the movable member 474 toward the fixed member 476 toward the closed position. As the belt tensioner 450 is swung toward the opening 452 and the clasp 472, the shaft 458 may engage with the 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., inclined) such that the engagement between the shaft 458 and the forward-facing surface 480 pushes the movable member 474 toward the fixed member 476 toward the opposite direction of the biasing mechanism. As the shaft 458 moves beyond the forward-facing surface 480, the biasing causes the movable member 474 to rotate toward the fixed member 476, thereby enclosing the shaft 458 within the opening 478.

[0166] The actuator 482 is operably coupled to at least one latch 472, selectively opening the at least one latch 472 to release the belt tensioner 450. Although the actuator 482 is shown positioned directly adjacent to the belt tensioner locking mechanism 470, it should be understood that embodiments in which the actuator 482 is positioned at a distance from there are also within the scope of this disclosure. The actuator 482 is operably coupled to the movable member 474 of the at least one latch 472 by a link mechanism 484 (see Figure 45) or other suitable connection. Thus, when a force is applied to the actuator 482 (for example, when the actuator 482 is pushed down), that force is transmitted to the movable member 474 via the link mechanism 484. The force counteracts the biasing of the biasing mechanism, thereby separating the movable member 474 from the fixed member 476. In the separated or open position, the belt tensioner 450 can be separated from the belt opening 452.

[0167] As shown above, at least a portion of the child safety seat 24 is detachably connectable to the third base member 86. In embodiments, the seat pan portion 28 is detachable from the third base member 86 (for example, from its base member seat portion 88). Referring to Figures 5-7 and 33, the base member seat portion 88 may include at least one upwardly projecting mounting member (for example, extending from the surface 110 along the direction between the rear end and the front end). In the non-limiting embodiments illustrated in Figures 5-7 and 33, a first mounting member 120 is included, positioned substantially centrally between the lateral sides of the base member seat portion 88. Furthermore, two substantially identical second mounting members 122 may be positioned laterally spaced from the first side 124 and the second side 126 of the first mounting member 120, respectively. However, it should be understood that embodiments including a single mounting member and / or at least one mounting member positioned at other locations around the base member seat portion 88 are also intended herein. Each mounting member 120, 122 may be formed as a pipe, rod, block, or any other suitable shape. One or more mounting members 120, 122 may be formed from a suitable, rigid material, fixedly attached to the base member seat portion 88, or formed integrally with the body of the third base member 86.

[0168] As shown in Figures 6, 7, 36A, and 36B, at least one positioning feature 130 (e.g., a groove) is formed on one or more surfaces of the sheet pan portion 28 of the child safety seat 24 (e.g., the bottom surface 132 of the sheet pan portion 28 configured to abut the top surface 110 of the sheet pan portion 28). Each sheet positioning feature 130 may be complementary in size and / or shape to a corresponding one of the mounting members 120, 122, thereby allowing the mounting member to be accommodated therein. This alignment and / or fitting between the mounting members 120, 122 and the sheet positioning feature 130 ensures that the sheet pan portion 28 adjacent to the base member sheet portion 88 is properly positioned or located.

[0169] In one embodiment, the seat pan portion 28 of the child safety seat 24 is loosely positioned around the support base (e.g., the base member seat portion 88). As used herein, the term “loosely positioned” describes an embodiment in which the seat pan portion is simply positioned in contact with the support base, but is not otherwise connected to the support base. As a result, in this loosely positioned configuration, the user can easily separate the seat pan portion 28 from the support base 22 by simply lifting and / or rotating the seat pan portion 28 away from the third base member 86. The weight of the occupant may be sufficient to limit unintended separation of the seat pan portion 28 from the third base member 86. In another embodiment, the seat pan portion 28 may be coupled to or attached to the third base member 86 via a booster locking mechanism. In such an embodiment, the booster locking mechanism prevents unintended separation of the seat pan portion 28 from the third base member 86. Therefore, for example, before separating the sheet pan portion 28 from the third base member 86, the booster locking mechanism must be released, for example, by removing the corresponding parts of the booster locking mechanism.

[0170] An example of a booster locking mechanism 370 is shown in Figure 34. As shown, the booster locking mechanism 370 includes at least one locking member 372 movably mounted on the sheet pan portion 28. In the illustrated non-limiting embodiment, the locking member 372 is pivotably mounted on the underside of the sheet pan portion 28 (for example, near the first sheet side member 56 or the second sheet side member 60). The locking member 372 includes an elongated body 374. The elongated body 374 has a fitting feature 376 located at its first end and an operating surface 378 located, for example, near its second end. The fitting feature 376 may be oriented at an angle nonparallel 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 (illustrated). In the locked position, the fitting feature portion 376 extending from the main body 374 is positioned in contact with or abutting the surface of the third base member 86.

[0171] The actuator 380 is operably coupled to the locking member 372. Continuing to refer to Figure 34, and further to Figure 35, the actuator 380 includes a handle 382 positioned on the outer surface of the child safety seat 24. In the illustrated non-limiting embodiment, the handle 382 is positioned on the outer surface of the seat pan portion 28 (for example, one of the first seat side member 56 or the second seat side member 60). The handle 382 may be coupled directly or indirectly to the locking member 372. As illustrated, an actuation member 384 may extend from the surface of the handle 382 toward the interior of the seat pan portion 28. The actuation member 384 may be positioned in alignment with the actuation surface 378 of the locking member 372.

[0172] To operate the actuator 380 and unlock the sheet pan portion 28 from the third base member 86, the user applies a force F2 to the handle 382. In this embodiment, the user is configured to push or move the handle 382 inward. However, embodiments in which the handle 352 is moved in a different way (e.g., pulled outward or rotated) are also within the scope of this disclosure. This movement of the handle 382 causes the actuating member 384 to move and engage with the actuating surface 378, and the force is transmitted to the actuating surface 378. The force applied to the actuating surface 378 counteracts the biasing of the biasing member, 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 from the third base member 86 or disengaged from the third base member 86. Although only a single locking member 372 is shown in Figure 34, it should be understood that embodiments including multiple locking members are also within the scope of this disclosure. For example, the locking member 372 may be positioned adjacent to either the first seat side member 56 or the second seat side member 60. In such embodiments, a single actuator may be operably coupled to a plurality of locking members 372, or each actuator 380 may be associated with a corresponding locking member 372.

[0173] Referring to Figures 48 to 49B, another embodiment of the booster locking mechanism 500 is shown. The booster locking mechanism 500 includes at least one locking member 502 that is pivotably mounted on the sheet pan portion 28 (for example, the underside of the sheet pan portion 28). In this embodiment, the locking member 502 is a latch plate. Similar to the earlier embodiments shown in Figures 34 and 35, the latch plate 502 includes a fitting member 504 located at its first end and a release member 506 located, for example, near its second end. A recess 508 may be defined between the fitting member 504 and the release member 506. A biasing mechanism 510 (for example, a torsion spring) may be operably coupled to the latch plate 502. In this embodiment, the biasing mechanism 510 is operable to bias the latch plate 502 toward a first locked position (Figure 49A). In the first locked position, the pin or shaft 512 located on the third base member 86 is housed in the recess 508 and / or engaged by the fitting member 504 of the latch plate 502.

[0174] The sheet pan 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 located on the outer surface (e.g., its upper surface) of the sheet pan portion 28. The actuator 514 may be swivelably mounted on the sheet pan portion 28. When not in operation, the actuator 514 may be substantially coplanar with the upper surface of the sheet pan portion 28. In the 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 (e.g., its distal end 516) is configured to contact, for example, the release member 506 of the latch plate 502. In response to lifting the actuator 514, the actuator 514 swivels about its axis, thereby causing the distal end 516 to engage with the release member 506 of the latch plate 502 and apply force to it. 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 from the engagement member 504 of the latch plate 502. Once disengaged, the seat pan portion 28 can be separated from the rest of the child seat 24.

[0175] In some embodiments, the seat back portion 26 of the child safety seat 24 is not detachable from the support base 22. However, in other embodiments, both the seat pan portion 28 and the seat back portion 26 are detachable from the third base member 86. More specifically, the seat pan portion 28 may be detachably connected to the base member seat portion 88, and the seat back portion 26 may be detachably connected to the base member back portion 90 of the third base member 86. Furthermore, the seat pan portion 28 may be detachable from the seat back portion 26, thereby allowing the seat pan portion 28 and the seat back portion 26 to be detachable independently of the third base member 86.

[0176] In the illustrated non-limiting embodiments shown in Figures 8 to 12, the seat back portion 26 includes at least one (in some embodiments, more) seat interlock feature portion 140, such as a groove, recess, or opening. The base member back portion 90 may similarly include at least one base interlock feature portion 142 (such as a flange, rib, or other projection) configured to fit into, be housed in, or seat against each seat interlock feature portion 140. This fitting between the at least one seat interlock feature portion 140 and the at least one base interlock feature portion 142 ensures that the base member back portion 90 of the third base member 86 is properly positioned relative to the adjacent seat back portion 26.

[0177] In the non-limiting embodiment shown in Figure 12, the base interlock feature 142 is smaller than the corresponding sheet interlock feature 140. Thus, the base interlock feature 142 is accommodable within a first portion of the sheet interlock feature 140 and then movable (e.g., slidable) within a second portion of the sheet interlock feature 140. Within the second portion of the sheet interlock feature 140, the base interlock feature 142 may contact multiple surfaces of the sheet back portion 26 (e.g., the upper end 144 of the sheet interlock feature 140), thereby limiting unintended separation of the base interlock feature 142 from the sheet interlock feature 140.

[0178] In the embodiment, the base member back portion 90 includes at least one base interlock feature portion 142 protruding from near its bottom, and the seat back portion 26 includes at least one seat interlock feature portion 140 (e.g., an opening) capable of accommodating the base interlock feature portion. As shown in Figures 13A to 15, at least one base interlock feature portion 142 may extend through the seat back portion 26 so that at least the distal end 146 of the base interlock feature portion 142 is positioned substantially adjacent to the upright support surface 30. The seat back portion 26 may include a fitting feature portion 150 that is movable relative to the upright support surface 30 and can selectively fit with adjacent base interlock feature portions 142. In the illustrated non-limiting embodiment, the fitting feature portion 150 is a pin lock including a handle 152 and a pin 154 extending from the handle 152. The base interlock feature 142 includes an opening or through hole 148, the free end of the pin 154 can be accommodated within the opening 148, and the base interlock feature 142 (and therefore the third base member 86) is connected to the seat back portion 26.

[0179] The pin lock 150 may be movable to engage with the base interlock feature 142. For example, the pin lock 150 may be configured to slide along axis X between an unlocked position (Figure 13A) and a locked position (Figure 13B). In the unlocked position, the distal or free end of the pin 154 is spaced inward from the base interlock feature 142, and in the locked position, the pin 154 is housed within the opening 148 of the base interlock feature 142. In some embodiments, the pin lock 150 is also rotatable about an axis to hold the pin lock 150 in the locked position. As illustrated, the pin lock 150 may be rotatable from the plane of the upright support surface 30 between a first position in which the handle 152 extends at an angle non-parallel to the adjacent upright support surface 30 and a second position in which the handle 152 is at an angle substantially parallel to the adjacent upright support surface 30. One or more grooves or recesses 156 may be formed in the upright support surface 30 of the seat back portion 26, so that at least a portion of the handle 152 is positioned within the recess 156 when the pin 154 is in the locked position and the handle 152 is in the second position. Alternatively, or in addition to this, the pin 154 of the pin lock 150 may be positioned within the recess 156 (e.g., the same recess or different recesses). Such a configuration allows the handle 152 and / or the pin 154 to be positioned in a location that avoids or minimizes contact with the occupant's back. Furthermore, the handle 152 may include a tab, flange, or other feature portion 158 configured to engage with or abut against the corresponding surface of the recess 156 when the handle 152 is in the second position. This engagement can prevent unintended rotation of the handle 152 from the second position.

[0180] Although the movement and rotation of the pin lock 150 are described as occurring separately or sequentially, in other embodiments, the rotation of the pin lock 150 about axis X from a first position to a second position causes the pin lock 150 to move simultaneously along axis X between an unlocked position and a locked position. For example, a user may apply a downward force to the handle 152 to rotate the handle 152 about axis X, and as the handle 152 rotates downward, the pin lock 150 slides laterally and engages with the through hole 148 of the base interlock feature 142. The interface between the engaging feature 150 and the corresponding base interlock feature 142 shown and described herein is intended only as an example, and it should be understood that any suitable mechanism for detachably coupling the third base member 86 to the seat back portion is intended herein.

[0181] A portion of the child safety seat system 20 (for example, a support base 22) may include a harness 200 that can operate to secure a child to a child seat within the child safety seat system 20 when the child seat is in at least one of a plurality of configurations. In the illustrated, non-limiting embodiment, the harness 200 is attached to and positioned adjacent to a third base member 86. The harness (best shown in Figures 5–8) may include a plurality of harness straps (for example, shoulder straps, waist straps, and crotch straps, without limitation).

[0182] In embodiments, the harness 200 includes a crotch strap which is generally positionable between the occupant's legs and has a webbing piece 202 and a buckle 204 at its distal end (also shown in Figures 21A-21C). The harness 200 may further include a first strap 206 and a second strap 208, each having at least one webbing piece and a latch 210 configured to be selectively fastened to the buckle 204. The latch 210 can be releasably fastened or secured to the buckle 204 to secure the child to the child safety seat 24. Each of the first strap 206 and the second strap 208 may have a lap belt portion that can be positioned over the child's knees and a shoulder belt portion that can be positioned over the child's shoulders. In embodiments, the lap belt portion and shoulder belt portion of each strap 206, 208 are separate webbing pieces coupled to the latch 210. In another embodiment, the lap belt portion and the shoulder belt portion are integrally formed via a single webbing piece. In such an embodiment, the latch 210 is movable relative to the webbing piece, with the portion of the webbing located on the first side of the latch 210 forming the lap belt portion, and the portion of the webbing located on the second side of the latch 210 forming the shoulder belt portion.

[0183] In the embodiment, the end of the webbing 202 of the crotch strap (not shown) is attached to a portion of the support base 22 (for example, a third base member 86). Furthermore, the webbing 202 may extend through at least one attachment member (for example, a first attachment member 120). As illustrated, the first attachment member 120 may define a pocket 220 configured to house and store the crotch strap when the harness 200 is not being used to restrain the 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 stored in the pocket 220.

[0184] The ends of the lap belt portion and / or shoulder belt portion of each strap 206, 208 can be attached to a part of the support base 22 (e.g., a third base member 86). The ends of the lap belt portion and the shoulder belt portion can be joined to the third base member 86 at a position located below its upper surface 110. In the illustrated non-limiting embodiment, the end of each lap belt portion extends through a corresponding mounting member (e.g., each second mounting member 122).

[0185] The child safety seat 24 may have one or more openings for accommodating the straps of the harness 200 when the child safety seat 24 is mounted on the support base 22. For example, the shoulder belt portions of each strap 206, 208 may extend through respective slits (not shown) formed in the upright support surface 30 (or part of the headrest 46). In such embodiments, the slits may extend to the edge of the upright support surface 30 (e.g., the upper end) or the edge of the headrest to provide a path for attaching the shoulder belt portions. In embodiments where the shoulder belt portions extend through slits formed in the headrest 46, the harness is operably coupled to the headrest 46.

[0186] In the illustrated non-limiting embodiments shown in Figures 6, 7 and 21A, the seat pan portion 28 of the child safety seat 24 has a first opening 230 formed in a seat positioning feature portion 130 configured to overlap with a first mounting member 120. The first opening 230 is sized to accommodate a crotch strap buckle 204. Similarly, slits 232 are associated with each of the seat positioning feature portions 130 configured to abut against a second mounting member 122. As illustrated, the slits 232 form an opening in each seat positioning feature portion 130 and may extend beyond the seat positioning feature portion 130 in at least one direction to the edge of the seat pan portion 28 (e.g., the rear portion 54).

[0187] While the seat pan portion 28 of the child safety seat 24 is attached to the support base 22, the respective lap belt portions of the first strap 206 and the second strap 208 are fed into the slit 232 and pulled to position with one of the seat positioning features 130. The buckle 204 of the crotch strap can similarly be fed through the corresponding opening 230 formed in the respective seat positioning features 130. With the lap belt portions and crotch straps each accessible on the seat support surface 50 of the seat pan portion 28, the seat pan portion 28 can then be lowered into a predetermined position around the third base member 86 so that the seat positioning features 130 align and engage with the corresponding first and second mounting members 120 and 122. Once in place, the seat pan portion 28 can be coupled to the third base member 86 and / or the seat back portion 26 as described above. The harness 200 illustrated and described herein is intended only as an example, and it should be understood that any harness with any suitable configuration is intended herein.

[0188] The seat pan portion 28 may include at least one cup holder 520. In the non-limiting embodiments illustrated in Figures 50–52, the seat pan portion 28 includes a first cup holder 520 positioned on a first seat side member 56 and a second cup holder 520 positioned on a second seat side member 60. Although two cup holders 520 are illustrated, it should be understood that embodiments having only a single cup holder are also within the scope of this disclosure. The cup holder 520 may be positioned in front of a slot 66 formed in the seat side members 56, 60, which is configured to accommodate and position the lap belt portion of the vehicle belt. In one embodiment, the cup holder 520 is positioned to provide sufficient seating space for the seat occupant while simultaneously providing sufficient clearance for the support base 22 of the child restraint system 20. As illustrated, soft goods 522 may be configured to fit under a portion of the cup holder 520 (e.g., the rim 524 of the cup holder 520).

[0189] The cup holder 520 may be movable relative to the sheet pan portion 28 and, in some embodiments, may be removable. In embodiments, the cup holder 520 includes an elastic or flexible snap finger 526 extending from the bottom 528 of the cup holder. The flexible snap finger 526 is configured to engage with a projection 530 located inside the sheet pan portion 28 to restrict the separation of the cup holder 520 from the sheet pan portion 28. A flexible snap finger button 532 may be formed on the outer surface of the sheet pan portion 28 adjacent to a portion of the surface of the flexible snap finger 526. Applying force to the flexible snap finger button 532 causes the flexible snap finger 526 to disengage from the projection 530, thereby separating the cup holder 520 from the sheet pan portion 28. The removable nature of the cup holder 520 improves their appearance while simultaneously providing a finished look with adjacent soft goods 522.

[0190] Referring to Figures 73 to 75B, an example of a sheet pan portion 28 having a removable cup holder 900, similar to the cup holder 520, is shown in more detail. As illustrated, an actuation mechanism 902 associated with the cup holder 900 is operable to selectively release the cup holder 900 from the sheet pan portion 28. In the illustrated non-limiting embodiment, the actuation mechanism 902 is removablely coupled to the sheet pan portion 28. As illustrated, the actuation mechanism 902 may be housed within an opening 904 formed in the sheet pan portion 28 (for example, directly below the cup holder 900). The actuation mechanism 902 may include a body 906 having a first end 908 that can be positioned on the outside 910 of the sheet pan portion 28 (for example, sheet side members 56, 60, etc.). The body 906 further includes a slot 912, within which a flexible snap finger or other feature 914 extending the cup holder 900 can be housed. The main body 906 may further define a surface 916 that can be fitted by the end 918 of the feature portion 914 in order to limit the separation of the cup holder 900 from the sheet pan portion 28. In the embodiment, a biasing mechanism 920 is mounted inside the sheet pan portion 28 adjacent to the opening 904 and is operably coupled to the actuation mechanism 902 (for example, its second end 922). The biasing mechanism 920 is operable to bias the actuation mechanism 902 to the fitted position.

[0191] To detach the cup holder 90 from the sheet pan portion 28, the user applies force to the first end 908 of the actuation mechanism 902. This force counteracts the biasing force of the biasing mechanism 920, causing the body 906 to move within the opening 904 formed in the sheet pan portion 28. As a result of this movement, the surface 916 disengages from the flexible snap finger 914, thereby positioning the flexible snap finger 914 within the slot 912 formed in the body 906. When the actuation mechanism 902 is in this disengaged position, the cup holder 900 can be detached from the sheet pan portion 28 or installed relative to the sheet pan portion 28. As illustrated, when the cup holder 900 is not installed around the sheet pan portion 28, the actuation mechanism 902 may be removable from the sheet pan portion 28.

[0192] Next, various usage configurations of the Child Safety Seat System 20 are shown with reference to Figures 16 to 19. Figure 16 shows a usage configuration of the Child Safety Seat System 20 associated with infants or children weighing up to approximately 40 pounds. As illustrated, the Child Safety Seat 24 is connected to the support base 22 and is rear-facing. In the infant configuration, the child is restrained in the Child Safety Seat 24 using a harness 200 integrated with the Child Safety Seat System 20, and the support base 22 can be attached to the vehicle seat 10 using an integrated LATCH system or a vehicle belt. Another configuration of the Child Safety Seat System 20 shown in Figure 17 is associated with use by toddlers or children over 2 years of age, or children weighing approximately 25 to 65 pounds. In this toddler configuration, the Child Safety Seat 24 is connected to the support base 22 and is forward-facing. Similar to the infant configuration, in the toddler configuration, the child is restrained in the child safety seat 24 using the harness 200 of the child safety seat system 20, and the support base 22 can be attached to the vehicle seat 10 using an integrated LATCH system or a vehicle belt.

[0193] In other embodiments, the child safety seat 24 may be configured as a booster seat. For example, in an embodiment where both the seat pan portion 28 and the seat back portion 26 are detachable from the support base 22, as shown in Figure 18, the child safety seat 24 may be forward-facing and positioned 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 children weighing approximately 40 pounds to approximately 100 pounds. Furthermore, the child is restrained within the child safety seat 24 using a vehicle belt. 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 a booster configuration while 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 a vehicle belt rather than a harness 200.

[0194] In the backless booster configuration (Figure 19), only the seat pan portion 28 of the child safety seat 24 faces forward and is in direct contact with the vehicle seat. In the backless booster configuration, the support base 22 and the seat back portion 26 of the child safety seat 24 are absent. In this configuration, the child safety seat 24 may be suitable for use by children weighing approximately 40 pounds to 120 pounds, and the child is restrained against the seat pan portion 28 by a vehicle belt.

[0195] Referring to Figures 36A to 37B, the sheet pan portion 28 may include stabilizing legs 390. As illustrated, the stabilizing legs 390 may be positioned on or adjacent to the bottom surface 132 of the sheet pan portion 28. The stabilizing legs 390 may be movable relative to the body of the sheet pan portion 28. For example, a retractable stabilizing leg 390 may be movable between a first retracted configuration (Figures 36A and 37A) and a second extended configuration (Figures 36B and 37B). In the first retracted configuration, the front surface 392 of the stabilizing leg 390 is substantially aligned with an adjacent surface 394 of the body, while in the second extended configuration, the front surface 392 of the stabilizing leg 390 is axially offset from the adjacent surface 394 of the body. In an embodiment in which the main body is inclined downward from the front edge 52 of the seat support surface 50 toward the rear of the seat pan portion 28, the front surface 392 of the stabilizing leg 390 can be substantially aligned with the front edge 52 when in the retracted configuration. In the extended configuration, the bottom surface 396 of the stabilizing leg 390 (in addition to the bottom surface 132 of the seat pan portion 28) can be positioned in contact with the support surface (for example, the vehicle seat 10). Therefore, in the extended configuration, the contact area of ​​the seat pan portion 28 is increased, thereby increasing the stability of the seat pan portion 28.

[0196] In another embodiment shown in Figure 53, the sheet pan portion 28 may have a plurality of separate stabilizing legs 540. For example, a first stabilizing leg 540 may be positioned near the first sheet side member 56, and a second stabilizing leg 540 may be positioned near the second sheet side member 60. In embodiments including a plurality of separate stabilizing legs, the stabilizing legs 540 may have the same configuration, but are not necessarily required. As in the previous embodiment, the plurality of stabilizing legs 540 may be movable relative to the sheet pan portion 28 between a retracted configuration and an extended configuration. In embodiments including a plurality of stabilizing legs 540, the stabilizing legs 540 may operate simultaneously or may be movable independently of each other.

[0197] Refer to Figures 54–59 for a more detailed example of the stabilizing legs 540. In the retracted configuration, at least one stabilizing leg 540 may be positioned at least partially (in some embodiments, entirely) inside the sheet pan portion 28 (see Figure 55B). In embodiments, at least one stabilizing leg 540 has an inclined or angled front 542, and when the stabilizing leg 540 is in the retracted configuration, the front 52 is parallel or substantially parallel to the angled front 544 of the sheet pan portion 28. In the extended configuration, one or more stabilizing legs 540 protrude beyond the surface of the sheet pan portion 28 (e.g., the front 544). In the illustrated non-limiting embodiment shown in Figure 55A, when in the extended configuration, the bottom 546 of the stabilizing leg 540 is positioned at a distance from the bottom 548 of the sheet pan portion 28 and substantially aligned with the bottom 548 of the sheet pan portion 28. Therefore, both the bottom 546 of the stabilizing leg 540 and the bottom 548 of the seat pan portion 28 are positionable on a support surface (e.g., the vehicle seat 10) when the seat pan portion 28 is used independently of the rest of the child seat 24. In the embodiment, when at least one stabilizing leg 540 is in the extended configuration, the inclination angle of the seat pan portion 28 with respect to the vehicle seat is different from that of the seat pan portion 28 when at least one stabilizing leg is in the retracted configuration.

[0198] In some embodiments, at least one stabilizing leg 540 is rotatable between a retracted configuration and an extended configuration. However, embodiments in which at least one stabilizing leg 540 is translatable or movable in other ways are also intended herein. In the illustrated non-limiting embodiments, each stabilizing leg 540 of the sheet pan portion 28 is operably coupled to a respective retractor 550 by a link mechanism 552. As illustrated, the retractor 550 may include a fitting member 554 and a leg member 556 positioned obliquely to each other. Although the leg member 556 and the fitting member 554 are shown to be substantially perpendicular to each other, embodiments in which the members 554 and 556 are separated by a different angle are also within the scope of this disclosure. The retractor 550 is rotatable about an axis relative to the sheet pan portion 28. The link mechanism 552 is pivotably connected to the end of the leg member 554 and pivotably connected to a part of the stabilizing leg 540 (for example, near the rear 558 of the stabilizing leg 540).

[0199] The biasing mechanism 560 is operably coupled to the stabilizing leg 540, biasing the stabilizing leg 540 into an extended configuration. In the illustrated non-limiting embodiment, the biasing mechanism 560 is connected to the retractor 550, but embodiments including the biasing mechanism 560 in another suitable location are also intended herein. When the seat pan portion 28 is separated from the third base member 86 of the child seat 24, the biasing force of the biasing mechanism 560 causes the corresponding stabilizing leg 540 to automatically transition from a retracted configuration to an extended configuration. Thus, when the seat pan portion 28 is not attached to the child seat 24, the stabilizing leg 540 is extended to enhance the stability of the seat pan portion.

[0200] The stabilizing leg 540 may be automatically retractable in response to connecting the seat pan portion 28 to the child seat 24 (for example, a third base member 86). In an embodiment, the third base member 86 includes a booster receiver 562 (Figure 57) positioned in alignment with a corresponding retractor 550. When the seat pan portion 28 is attached to the third base member 86, the booster receiver 562 engages with the corresponding retractor 550. This engagement applies a force to the retractor 550, causing it to rotate around its axis (for example, toward the front of the seat pan portion 28). This rotation of the retractor 550 drives a corresponding rotation of the stabilizing leg 540 in the opposite direction. Thus, as the retractor 550 is rotated by the booster receiver 562, the stabilizing leg 540 rotates in the opposite direction (for example, toward the interior of the seat pan portion 28 and toward the retractor 550) via the linkage mechanism 552. The retractor 550 is held in this rotational position while the sheet pan portion 28 remains connected to the third base member 86. When the sheet pan portion 28 is separated from the third base member 86, the retractor 550 rotates due to the biasing force acting on it, and the corresponding stabilizing legs 540 are driven forward to extend into an extended configuration.

[0201] Referring to Figures 58 to 59B, in another embodiment, instead of being operably coupled by a linkage mechanism, the leg member 554 of the retractor 550 may be directly pinned to the stabilizing leg 540 (via pin 564). The operation of such a configuration is substantially identical to that of the embodiments in Figures 54 to 57. As previously stated, the engagement with the booster receiver 562 drives the retractor 550 (and thus the stabilizing leg 540 coupled to the retractor 550) into a retracted configuration. When the sheet pan portion 28 is separated from the third base member 86, the biasing force of the biasing mechanism 560 acting on the retractor 550 causes the retractor 550 to rotate automatically, thereby driving the stabilizing leg 540 forward into an extended configuration.

[0202] Referring next to Figures 60A and 60B, in the embodiment, at least a portion of the metal structural frame of the support base 22 is formed from aluminum. For example, at least one of the rigid frame 80 of the second base member 78 and the spin carriage 92 of the third base member 86 may be formed from aluminum. However, it should be understood that while a portion of the structural frame of the support base 22 may be formed from aluminum, other portions of the structural frame may be formed from a different material (e.g., steel). In the non-limiting embodiment shown in the figures, both the rigid frame 80 and the spin carriage 92 are formed from a first material (e.g., aluminum). In such an embodiment, one or more components located at the interface between the rigid frame 80 and the spin carriage 92 are formed from a second material (e.g., steel). As shown, the bottom spin cover 99 located between the rigid frame 80 and the spin carriage 92 is formed from steel. Similarly, the base anchor members 104 positioned near the ends of the rigid frame 80 and the sheet anchor members 108 positioned at corresponding locations on the spin carriage 92 may be formed from steel. Using such a combination of materials may require additional bolt connections. However, it should be understood that embodiments in which the structural frame of the support base 22 is formed from a different material or a combination of different materials, including a metal alloy having sufficient strength for the application, are also within the scope of this disclosure.

[0203] The headrest 46 of the child seat 24 described herein may be movable relative to the upright support surface 30 of the child seat 24 between a retracted position and an extended position and can be adjusted based on the size of the child positioned in the child seat 24. A locking mechanism 600 that can operate to selectively lock the headrest 46 in a predetermined position relative to the child seat 24 typically includes a component associated with the headrest 46 that can be housed in the upright support surface 30 or in one of a plurality of openings of a slot 602 formed in a channel 604 adjacent to the upright support surface 30. In embodiments, a portion of the spin carriage 92 forms a channel 604 containing a plurality of slots 602 that define the respective positions of the headrest 46.

[0204] In embodiments where the spin carriage 92 is formed from an aluminum material, existing locking mechanisms may not be suitable for interaction with the aluminum component. In the illustrated non-limiting embodiments, the locking mechanism 600 includes a first locking member 610 operably coupled to a second locking member 612. The first locking member 610 may be movable relative to the headrest 46 (e.g., rotatable about an axis) between a locked position in which the first locking member 610 engages with the slots 602 (Figures 62A, 62B, 63A, and 64A) and an unlocked position in which the first locking member 610 is separated from or disengaged from the multiple slots 602 (Figures 63B and 64B). The second locking member 612 is also movable relative to the headrest 46. For example, the second locking member 612 may be rotatable about an axis between the unlocked position and the engaged position. In the illustrated non-limiting embodiments, the type and / or direction of movement of the second locking member 612 differs from that of the first locking member 610. As illustrated, the axis of rotation of the second locking member 612 is positioned at an angle non-parallel to the axis of rotation of the first locking member 610. For example, the axes may be perpendicular to each other. However, any suitable configuration of the first locking member 610 and the second locking member 612 is within the scope of this disclosure. A biasing mechanism 614 (e.g., a torsion or spring) may be operably coupled to the first locking member 610 to bias the first locking member 610 and engage it with an adjacent slot 602.

[0205] The locking mechanism 600 may be part of an actuation mechanism 620 related to the movement of the headrest 46. In embodiments, the actuation mechanism 620 includes at least one link member 622. Although only a single link member 622 is shown in the figure, it should be understood that in some embodiments, the actuation mechanism 620 may include multiple link members 622 (for example, link members related to each channel 604 of the slot 602 and the corresponding locking mechanism 600). In the illustrated non-limiting embodiment, a portion of the second locking member 612 can be accommodated within an opening 624 formed in the link member 622 when the actuation mechanism 620 is not actuated.

[0206] The operating mechanism 620 further includes an actuator 626 (e.g., a handle) located outside the headrest 46 for user access. In the illustrated, non-limiting embodiments, the actuator 626 is located at or near the top of the headrest 46. At least one link member 622 is operably coupled to the actuator 626. For example, a first end (not shown) of each link member 622 may be connected to the actuator 626 or, in some embodiments, formed integrally with the actuator 626.

[0207] The first locking member 610 is disengaged from its respective slot 602 in response to the operation of the actuator 626 (for example, by applying force to the actuator 626). When disengaged, the headrest 46 is movable relative to the child seat 24. When a user applies force to the actuator 626, the force is transmitted to at least one link member 622, which moves relative to the headrest 46. As the link member 622 moves, its surface engages with the second locking member 612 and applies force to it, causing the second locking member 612 to rotate toward the first locking member 610 about its axis. As it rotates, the second locking member 612 engages with a portion of the first locking member 610. The force transmitted to the first locking member 610 by the second locking member 612 counteracts the biasing force of the biasing mechanism 614, thereby causing the first locking member 610 to rotate and disengage from the slot 602.

[0208] When actuator 626 is released, the biasing force of biasing mechanism 614 causes the first locking member 610 to rotate and engage with the corresponding slot 602. The rotation of the first locking member 610 drives a similar rotation of the second locking member 612. As the second locking member 612 rotates around its axis, a force is applied to the corresponding portion of link member 622, causing link member 622 to move downward, thereby housing the second locking member 612 within the opening 624 of link member 622.

[0209] Another embodiment of the headrest locking mechanism 600 associated with the headrest 46 is shown in Figures 65 to 69B. As illustrated, the locking mechanism 600 includes a single locking member 640 having a first or inclined fitting member 642 and a second or slotted fitting member 644. The locking member 640 may be positioned in direct contact with a portion of a link member 646. In the illustrated non-limiting embodiment, the link member 646 includes an opening 648 and an inclined surface 650 extending from the opening 648. However, it should be understood that embodiments in which the link member 646 does not include the opening 648 are also within the scope of this disclosure. A biasing mechanism 652 is operably coupled to the locking member 640 to bias the slotted fitting member 644 into a slot associated with the position of the headrest 46 (for example, slot 602 (see Figures 69A to 69B)).

[0210] As previously mentioned, the link member 646 may be operably coupled to an actuator 654 accessible by the user, and in some embodiments, may be formed integrally with the actuator 654. In response to the application of force to the actuator 654, the link member 646 moves relative to the headrest 46. As the link member 646 moves, the inclined fitting member 642 slides along the inclined surface 650. As the inclination of the inclined surface 650 increases, this fitting causes the locking member 640 to pivot about its longitudinal axis. This rotation of the locking member 640 counteracts the biasing force of the biasing mechanism 652, moving the slot fitting member 644 out of the corresponding slot 602 (Figures 67B, 68B, and 69B). As shown in Figures 68A to 69B, the release slot 656 may be formed in a part of the headrest 46 (e.g., the headrest shell 47) aligned with the slot fitting member. Therefore, when the slot fitting member 644 rotates and disengages from the slot 602 associated with the child seat, the slot fitting member 644 is housed in 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, thereby disengaging the inclined surface 650 from the inclined fitting surface. Furthermore, the biasing force of the biasing mechanism 652 causes the locking member 640 to rotate and return to engagement with the corresponding slot 602, locking the headrest into the slot. However, it should be understood that in some embodiments, the biasing force of the biasing mechanism 652 may be sufficient to both move the inclined surface 650 away from the inclined fitting member 642 and rotate the locking member 640 about its axis.
