[0215] A detailed description of one or more embodiments of the disclosed apparatus and methods is provided herein by way of example and not limitation with reference to the accompanying figures.

[0216] Referring now to the drawings, various examples of child safety seat systems 20 are shown. In each of the non-limiting embodiments shown, the child safety seat system 20 includes a support base 22 that can be removably secured to the vehicle seat 10 (see FIG. Figure 1 The support base 22 may be secured to the vehicle seat 10 in a removable manner via a vehicle safety belt associated with the vehicle seat 10.

[0217] The child safety seat system 20 additionally includes a child safety seat 24 associated with the 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, the support base 22 and at least a portion of the child safety seat 24 can be permanently connected or attached together, as will be described in more detail below. As used herein, the term "permanently connected" refers to an embodiment in which the child safety seat 24 or a portion thereof is not intended to be detached from the support base 22 by a user.

[0218] The child safety seat 24 includes a seat back portion 26 and a seat pan portion 28 disposed at an angle relative to the seat back portion 26. The seat pan portion 28 may, but need not, be configured to be removably 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 that 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 disposed at a first side 38 of the upright support surface 30, and a second upright side member 40 may be disposed at a 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 left and right sides of the seat back portion 26, respectively. As shown, 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 generally orthogonally to the upright support surface 30, or alternatively, may extend therefrom at another angle, such as 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 within which the upper body of a child is received.

[0219] The upright side members 36, 40 can facilitate proper positioning of a vehicle safety belt during one or more operating modes when the child safety seat 24 is installed in a vehicle. Although not shown, in some embodiments, each upright side member 36, 40 has an opening formed therein. The opening can be configured to receive a vehicle safety belt (not shown) to secure the child safety seat 24 to the vehicle seat 10 in a forward-facing configuration or to secure the upper body of a child positioned within the cavity.

[0220] exist Figures 21A to 23In the non-limiting embodiment shown in FIG. 1 , the seat back portion 26 is an assembly including a seat back 27, wherein an upright support surface 30 and a first upright side member 36 and a second upright side member 40 extend angularly therefrom as previously described. A separate back cover or seat back shell 29 can be positioned in contact with the rearward-facing surface 31 of the seat back 27. In the non-limiting embodiment shown, the seat back shell 29 has a size and shape complementary to the seat back 27, such that 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 has a configuration that covers only a portion of the rearward-facing surface 31 of the seat back 27 are also within the scope of the present invention. In such embodiments, the seat back shell 29 is formed of a first material, such as plastic or a composite material, and the seat back 27 can be formed of a different second material, such as polystyrene or a high-density foam. In addition, a textile (not shown) can be attached to the inward-facing surface of the seat back 27 to provide cushioning for a child sitting in the backrest area.

[0221] Continue to refer Figures 21A to 23 In the non-limiting embodiment shown, a seat back panel 33 is mounted in an overlapping arrangement 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 generally rectangular and has a length approximately equal to the distance between the top 32 and the bottom 34 of the upright support surface 30 and a width generally equal to the distance between the first side 38 and the second side 42 of the upright support surface 30. In other embodiments, the seat back panel 33 may cover only a portion of the upright support surface 30, or alternatively, may extend beyond the upright support surface 30, such as in an overlapping arrangement with one or both of the first upright side member 36 and the second upright side member 40.

[0222] Regardless of the configuration of the seat back portion 26, in a non-limiting embodiment, one or more shock absorbers or side impact pods 37 designed to absorb forces in the event of an accident or collision may be disposed at the outer surface 35 of the seat back portion 26. Figures 21A to 23, but it should be understood that embodiments with multiple impact chambers 37 are within the scope of the present invention. As shown, the at least one impact chamber 37 can be arranged near the top 32 of the seat back portion 26. In one embodiment, for example, when the child safety seat 24 is in a forward-facing configuration, the at least one impact chamber 37 can be arranged at a position vertically positioned above the support base 22. In addition, when the child safety seat system 20 is installed around the vehicle seat 10, the at least one impact chamber is arranged without contact with the vehicle seat 10. However, embodiments including the impact chamber 37 arranged in another position alternatively or additionally are also covered herein. In the non-limiting embodiment shown, the impact chamber 37 is generally centrally arranged and extends or wraps around the outer surface 35 toward at least one of the first upright side member 36 and the second upright side member 40, and in some embodiments toward both. Therefore, the at least one impact chamber 37 can substantially surround the rear portion of the seat back portion 26. However, it should be understood that embodiments in which one or more impact pads 37 are positioned only at the center of the seat back portion, such as generally aligned with the upright support surface 30, or only on one side of the outer surface, such as aligned with one of the upright side members 36, 40 are also contemplated herein.

[0223] In the non-limiting embodiment shown, the seat back portion 26 of the child safety seat 24 includes a headrest 46. The headrest 46 can be attached to the seat back portion 26 or can be integral with the seat back or can be removably coupled thereto. The headrest 46 can be fixed, or in some embodiments, can be configured to move relative to the upright support surface 30. For example, the headrest 46 can be configured to translate between a retracted position and an extended position relative to the upright support surface 30, 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 seat back portion 26 does not include a headrest 46 are also contemplated herein.

[0224] refer to Figure 5 , 624A to 24C, in one embodiment, the headrest 46 includes a body, generally designated 300, having a head support surface 302. A first head side component 304 may be disposed at a first side 306 of the head support surface 302, and a second head side component 308 may be disposed at a second opposite side 310 of the head support surface 302. The first head side component 304 and the second head side component 308 form respective left and right sides of the headrest 46. The first head side component 304 and the second head side component 308 extend forward from the head support surface 302. Thus, the head support surface 302 and the first head side component 304 and the second head side component 308 define a headrest area or cavity within which the head of a child positioned in the child safety seat 24 is received. The first head side component 304 and the second head side component 308 may extend generally orthogonally to the head support surface 302, or alternatively, may extend therefrom at another angle, such as an angle greater than 90°. The angle of at least one of the first head side component 304 and the second head side component 308 relative to the head support surface 302 may be equal to or may be different from the angle of a corresponding one of the first upright side component 36 and the second upright side component 40 relative to the upright support surface 30 .

[0225] In one embodiment, if Figures 24A to 24C As shown in FIG. 1 , the body of the headrest 46 is an assembly including a first portion 312 having a head support surface 302 and a first head side component 304 and a second head side component 308 extending angularly therefrom as described. A second portion 314 including a headrest cover or panel can be positioned in contact with a rearward-facing surface (not shown) of the first portion 312. In the non-limiting embodiment shown, the second portion 314 has a size and shape complementary to the first portion 312, so that the second portion 314 substantially overlaps the entire rearward-facing surface of the first portion 312. In such embodiments, the second portion 314 can be a structural shell formed of a first material such as plastic, and the first portion 312 can be formed of a different second material such as polystyrene or high-density foam. A textile (not shown) can be arranged at one or more surfaces of the first portion 312 facing the headrest area to provide cushioning for a child sitting in the child safety seat 24. In one embodiment, a channel 316 is formed between the first portion 312 and the second portion 314, and a portion of the textile is arranged in the channel 316 to couple the textile to the headrest 46. However, any suitable means for attaching soft goods to the head restraint 46 are contemplated herein.

[0226] The headrest 46 may include at least one shoulder belt guide 320 having an opening 322 therein for receiving a vehicle seat belt. The shoulder belt guide 320 may be integrally formed with the body of the headrest, or alternatively, may be a separate component attached thereto. Figures 24A to 24C As shown in , the at least one shoulder belt guide 320 can be aligned with a portion of the main body 300 and installed as an extension of the portion. For example, the at least one shoulder belt guide 320 can be positioned at the bottom surface of one or both of the first head side component 304 and the second head side component 308. The shoulder belt guide 320 can have a shape complementary to an adjacent portion of the main body 300, so that the shoulder belt guide is flush with the main body and defines a portion of the contour of the headrest 46. The at least one shoulder belt guide 320 can be permanently attached to the main body 300, or alternatively can be removably connected thereto. In the non-limiting embodiment shown, the shoulder belt guide 320 is attached to the main body 300 using one or more fasteners, for example, at a position between the first portion 312 and the second portion 314. However, it should be understood that any suitable means for removably connecting the shoulder belt guide 320 to the main body 300 of the headrest 46 at any position is within the scope of the present invention.

[0227] The seat pan portion 28 of the child safety seat 24 can include a seat support surface 50 that faces generally upward and 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 component 56 can be disposed at a first side 58 of the seat support surface 50, and a second seat side component 60 can be disposed at a second, opposite side 62 of the seat support surface 50. The first seat side component 56 and the second seat side component 60 extend upward and extend from left and right sides of the seat portion. The seat support surface 50 and the first seat side component 56 and the second seat side component 60 define in combination an area within which at least a portion of a child's lower body can be received.

[0228] As shown, the seat side components 56, 60 extend at an angle from the seat support surface 50. The angle of the first seat side component 56 relative to the seat support surface 50 may be the same as the angle of the first upright side component 36 relative to the upright support surface 30, but this need not be the case. Similarly, the angle of the second seat side component 60 relative to the seat support surface 50 may be the same as the angle of the second upright side component 40 relative to the upright support surface 30, but this need not be the case.

[0229] In the illustrated non-limiting embodiment, each seat side member 56, 60 has a slot 66 formed therein that is configured to function as a leg strap guide during at least one use mode of the child safety seat 24. In some operating modes of the child safety seat 24, the slot 66 may be configured to receive and position a leg strap portion of a vehicle restraint or separate restraint belt to secure a child within the child safety seat 24. As will be described in greater detail, the rotational configuration and / or tilt of the child safety seat 24 may be adjusted when the child safety seat 24 is connected to the support base 22.

[0230] The child safety seat 24 generally includes a first booster portion and a second booster portion, and in one embodiment, the seat back portion 26 can be considered the first booster portion and the seat pan portion 28 can 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 contemplated herein. The first booster portion can, but need not, be configured to be removably coupled to the second booster portion. Fig. 20A and 20B In the non-limiting embodiment shown in , the seat back portion 26 includes at least one seat back engagement feature 67, and the seat pan portion 28 includes at least one seat pan engagement feature 68 that can selectively engage with the corresponding seat back engagement feature. As shown, the seat back engagement feature 67 can be a protrusion extending from near the second end 34, and the seat pan engagement feature 68 can be a corresponding recess or opening formed in the surface of the seat pan portion 28 and aligned with the protrusion. Therefore, the protrusion can be received in the recess to connect the seat back portion 26 to the seat pan portion 28. However, embodiments in which the seat pan engagement feature 68 is a protrusion and the seat back engagement feature 67 is a recess are also covered herein. In addition, other suitable mechanisms for removably connecting the seat back portion 26 to the seat pan portion 28 are also within the scope of the utility model.

[0231] The support base 22 for mounting the child safety seat 24 includes a base body having a base seat portion 70 and a base rear portion 72 (see FIG. Figure 1 ). For example, suitable materials for making the base body include, but are not limited to, rigid plastics or composite materials. The base seat portion 70 and the base rear portion 72 can be integrally formed as a single body, or alternatively can be formed by separate components that are removably or permanently connected together.

[0232] View now Figure 2In the non-limiting embodiment shown, the support base 22 includes a first base member 74 having a bottom surface 76 suitable for placement on a support surface such as a vehicle seat 10, and a second base member 78 coupled to the first base member 74. The first base member 74 can be a reclining foot and / or the second base member 78 can include a rigid frame 80 at least partially contained within a structural shell 82. At least a portion of the second base member 78 can be positioned in an overlapping arrangement with an upper surface 84 of the first base member 74. In the non-limiting embodiment shown in the figures, the first base member 74 is only disposed at the base seat portion 70 of the support base 22, and the second base member 78 forms a portion of both the base rear portion 72 and the base seat portion 70. However, embodiments in which the first base member 74 forms a portion of both the base rear portion 72 and the base seat portion 70 are also contemplated herein. Referring to the figures, in one embodiment, the support base 22 includes a third base member 86, such as 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 located at the base seat portion 70 of the support base 22, and may include a base member rear portion 90 extending at an angle from the base member seat portion 88.

In one embodiment, as Figure 3 , 4 As shown in FIGS. 25 to 27 , near the bottom of the third base member 86, the spin bracket 92 includes a circular flange 98, such as an edge that has been rolled or otherwise formed to form a seat anchor or rim 100. A portion of the second base member 78, such as the rigid frame 80, may include one or more hooks or anchors 102 (see FIG. Figure 3 and 25 ), which has a curvature configured to engage edge 100. In e.g. Fig. 22 and 27 In some embodiments shown in FIG. 8 , the bottom spin cap 99 can be positioned vertically below the circular flange 98. In such embodiments, the bottom spin cap 99 can but need not be mounted to the circular flange 98.

[0236] In one embodiment, the third base member 86 can rotate about an axis between a plurality of configurations relative to the first base member 74 and the second base member 78 of the support base 22. In one embodiment, the third base member 86, and therefore the child safety seat 24 that can be connected to the third base member 86, can rotate relative to both the first base member 74 and the second base member 78 of the support base 22. For example, the engagement between the edge 100 and the corresponding hook 102 formed on the second base member 78 can define a rotational path of the third base member 86 relative to the first base member 74 and the second base member 78, and therefore define a rotational path of the child safety seat 24 relative to the support base 22. Figure 4 , 16 17, the third base member 86, and therefore the child safety seat 24 that can be connected to the third base member 86, can be in a first rotational configuration, such as where the child safety seat 24 is in a forward-facing position ( Figure 1 and 3 ) configuration, and a second rotational configuration, such as one in which the child safety seat 24 is in a rearward facing position ( Figure 4 and 16 However, it should be understood that embodiments in which the child safety seat 24 can be positioned in one or more additional configurations between the first rotational configuration and the second rotational configuration are also within the scope of the present invention.

[0237] The spin lock 330 may be used to selectively lock the rotation of the third base member 86, and therefore the child safety seat 24 coupled to the third base member 86, in one of a plurality of configurations relative to the support base 22. Fig.28A and 28B , an example of a spin lock 330 is shown in more detail. As shown, the spin lock 330 is arranged in a portion of the second base member 78 at the base seat portion 70 of the support base 22. With reference to the non-limiting embodiment shown, the spin lock 330 includes a centrally located connecting rod 332 that can rotate around the axis X. In one embodiment, the connecting rod 332 can be appropriately mounted to the support base 22 via bolts or other suitable fasteners. As shown, the connecting rod 332 can have two end segments 334 extending outwardly therefrom, for example, disposed on opposite sides of the connecting rod 332 relative to the axis of rotation. A plurality of locking pins 336, for example two locking pins, are connected to the connecting rod 332. For example, the first end 338 of each locking pin 336 is connected to the corresponding end segment 334 of the connecting rod 332. As shown, the locking pins 336 can extend from the connecting rod 332 in opposite directions.

[0238] The locking pin 336 may be in a first locked position ( Fig.28A) and a second unlocked position in which the child safety seat 24 can rotate freely relative to the support base 22 ( Fig.28B ). When each of the locking pins 336, and therefore the spin lock 330, is in the locked position, the second opposite end 340 of the locking pin 336 is received in a corresponding lock segment 342, such as a groove or opening formed in a portion of the support base 22. When the locking pins 336, and therefore the spin lock 330, are in the second unlocked position, the second end 340 of the locking pin 336 is separated from the lock segment 342, thereby allowing the child safety seat 24 to rotate relative to the second base member 78. In the non-limiting embodiment shown, the plurality of lock segments 342 are formed in the second base member 78. However, embodiments in which the plurality of lock segments 342 are formed in the first base member 74 or another suitable component are also contemplated herein. In one embodiment, a biasing member (not shown), such as a torsion spring, is operably coupled to the link 332 to bias the link 332, and therefore the locking pin 336, to the first locked position.

[0239] Continue to refer Fig.28A and 28B , and further reference Figures 29 to 32B , at least one actuator 350 is operably coupled to at least one of the locking pins 336. In the illustrated non-limiting embodiment, a plurality of actuators are operably coupled to the spin lock 330. As shown, a first actuator 350a is operably coupled to the first locking pin 336 and a second actuator 350b is operably coupled to the second locking pin 336. Each actuator 350a, 350b can be independently or individually operated to transform the locking pin 336 from a locked position to an unlocked position. Alternatively or in addition, the first actuator 350a and the second actuator 350b can be operated simultaneously to transform the locking pin 336 from a locked position to an unlocked position.

[0240] In the non-limiting embodiment shown, the plurality of actuators 350a, 350b are substantially identical and include handles 352 disposed at an outer surface of the child safety seat 24. The handles 352 may be directly or indirectly connected to the locking pins 336. As shown, each handle 352 is operably coupled to a corresponding locking pin by a wire, cable or other suitable tensioning member 354. The handles 352 may be part of or integral with a drive component 356 pivotally mounted to the child safety seat 24. In such embodiments, the drive component 356 is positioned such that the handles 352 extend through an opening in, for example, the seat back shell 29 and are exposed at an exterior of the child safety seat 24. However, embodiments in which the handles 352 are separate from the drive component 356 and operably coupled to the drive component are also contemplated herein. An engagement link 360 connected to the tensioning member 354 may be movably coupled to the drive component 356.

[0241] In the non-limiting embodiment shown, the drive member 356 has an angled slot 362 formed therein, and a pin 364 that extends through an opening 366 formed in the engagement link 360, for example, near one end thereof, is also received within the slot 362. The pin 364 is configured to translate within the slot 362 in response to rotation of the drive member 356. Due to the angled configuration of the slot 362, this translation of the pin 364 and the engagement link 360 relative to the drive member 356 applies a force to the tensioning member 354. Fig.31 As shown, the drive component 356 , the engagement link 360 , and a portion of the tensioning member 354 may be embedded within the seat back portion 26 , such as between the seat back 27 and the seat back shell 29 .

[0242] To operate the actuator 350a to unlock the spin lock 330, the user applies a force F1 ( Fig.32A ). In one embodiment, the user operates to rotate the handle 352 forward. However, embodiments in which the handle 352 moves in another manner, such as translating inward or pushing or pulling outward, are also within the scope of the present invention. This movement of the handle causes the drive member 356 to rotate about its axis, so that the pin 364 of the engagement link 360 moves upward in the slot 362 (see Fig.32B ). Thus, in response to the force applied to the handle 352, a force is applied to the corresponding locking pin 336 in a direction opposite to the bias of the biasing member. The movement or translation of the first locking pin 336 causes the link 332 to rotate about its axis X against the bias of the biasing member. Because the second locking pin 336 is also coupled to the link 332, the rotation of the link 332 via the first locking pin 336 causes a similar inward movement of the second locking pin 336. Via this inward movement, the second ends 340 of the two locking pins 336 disengage from the corresponding lock segments 342 of the support base 22. With the actuators 350a, 350b operated and the locking pins 336 disengaged from the lock segments 342, the user can then rotate the child safety seat 24 relative to the support base 22 to a desired rotational configuration.

[0243] Once the child safety seat 24 has reached the desired rotational configuration, the user will release the actuators 350a, 350b. Upon release of the actuators 350a, 350b, the biasing force of the biasing member will cause the link 332 to rotate and the lock pin 336 to move (e.g., translate) outwardly into engagement with the corresponding lock segment 342 associated with the rotational configuration of the child safety seat 24. This force applied to the tension member 354 via this outward movement causes the engagement link 360 to translate relative to the slot 362 and the drive member 356 to rotate about its axis back to the unactuated position. It should be understood that the spin lock 330 shown and described herein is intended only as an example and that any suitable configuration is within the scope of the present invention.

[0244] Another embodiment of the spin lock 400 is Figures 38 to 40 . Similar to the previous embodiments, the spin lock 400 includes a center portion 402 that is movably mounted to the child seat 24. In the non-limiting embodiment shown, the center portion 402 can translate relative to the child seat 24. It should be understood that the child seat 24 can be rotationally coupled to the support base 22 via bolts or other suitable fasteners (403) at locations other than the spin lock 400.

[0245] As shown, the central portion 402 can include at least one engagement slot 404, such as a pair of engagement slots. At least one locking pin 406 can be fixed to the central portion 402. In the non-limiting embodiment shown, a pair of locking pins 406 are respectively movably coupled to the pair of engagement slots 404. As shown, the locking pins 406 can extend outward from the central portion 402 in opposite directions.

[0246] The locking pin 406 may be in a first locked position ( Fig.39A ) and a second unlocked position in which the child safety seat 24 can rotate freely relative to the support base 22 ( Fig.39B ). When each of the locking pins 406, and therefore the spin lock 400, is in the locked position, the distal end 408 of the locking pin 406 is received in a corresponding lock segment (not shown) formed in a portion of the support base 22. When the locking pins 406, and therefore the spin lock 400, are in the second unlocked position, the distal end 408 of the locking pin 406 is separated from the lock segment, thereby allowing the child safety seat 24 to rotate relative to the support base 22.

[0247] An actuator 410 (operably coupled to the central portion 402) Fig.40 ) is operable to transform the spin lock 400 between a locked position and an unlocked position. In a non-limiting embodiment, the actuator is shown as being located at the upright side member 36 of the seat back portion 28 of the child seat 24. However, embodiments in which the actuator 410 of the spin lock is arranged around the child seat 24 or even at another position around the support base 22 are also covered herein. When operated, the actuator 410 applies a force to the center portion 402. As shown, the engagement slot 404 formed in the center portion 402 is arranged at a non-parallel angle relative to the direction of movement of the center portion 402. Therefore, the locking pin 406 is configured to translate inwardly when the locking pin 406 moves in the engagement slot 404 in response to the actuator 410 applying a force to the center portion 402.

[0248] exist Figures 71A to 72, another embodiment of a spin lock 800 is shown in FIG. Similar to the previous embodiment, the spin lock 800 includes a centrally positioned connecting rod 802 that can rotate around an axis X. The connecting rod 802 can be mounted to the support base 22 via bolts or other suitable fasteners. As shown, the connecting rod 802 can have two end segments 804 extending outwardly therefrom, for example, disposed on opposite sides of the connecting rod 802 relative to the axis of rotation X. A plurality of locking pins 806, 808 can be connected to the connecting rod 802. Different from the previously described embodiments in which the two locking pins can be substantially identical, in the non-limiting embodiment shown, the first locking pin 806 has a first configuration and the second locking pin 808 has a second configuration different from the first configuration. As shown, the first locking pin 806 can be a generally rectangular shape, so that the first end 810 and the second end 812 of the first locking pin 808 are coaxial. The first end 810 of the first locking pin 806 can be connected to the end segment 804 of the connecting rod 802, and the second end 812 of the first locking pin 808 extends outwardly toward the outer periphery of the support base 22. The second locking pin 808 can include a first section 814 having a generally curved or arcuate profile and a second section 816 having a rectangular configuration coupled to or integrally formed with the first section 816. For example, the first end 818 of the second locking pin 808 formed at the first arcuate section 814 can be connected to the end segment 804 of the connecting rod 802, and the second end 820 of the second locking pin 808 arranged at the second section 816 can extend radially outward from the connecting rod 802. As shown, the second sections 816 of the first locking pin 806 and the second locking pin 808 can be coaxial. In addition, this axis of the second sections 816 of the first locking pin 806 and the second locking pin 808 can be spaced apart from or offset from the rotation axis X of the connecting rod 802, and thus do not intersect with it.

[0249] The first locking pin 806 and the second locking pin 808 may be in a first locked position (ie, a first locking position) in which the child safety seat 24 cannot rotate relative to the support base 22. Fig.71A ) and a second unlocked position in which the child safety seat 24 can rotate freely relative to the support base 22 ( Fig.71B ). When in the locked position, the second ends 812, 820 of the locking pins 806, 808 are received in corresponding lock sections (not shown) formed in a portion of the support base 22. When the locking pins 806, 808 and therefore the spin lock 800 are in the second unlocked position, the second ends 812, 820 of the locking pins 806, 808 are separated from the lock sections, thereby allowing the child safety seat 24 to rotate relative to the support base 22.

[0250] In the non-limiting embodiment shown, a portion of the first and second locking pins 806, 808, such as the second section 816, has slots 822, 824 formed therein, and pins or fasteners 826, 828 are disposed within the respective slots 822, 824. This engagement between the pins 826, 828 and the corresponding slots 822, 824 defines a path of movement for each of the first and second locking pins 806, 808. When the spin lock 800 is transformed between the locked position and the unlocked position, each slot 822, 824 translates relative to the respective pin 826, 828. The pins 826, 828 may be disposed adjacent to a first end of the slots 822, 824, such as the end of the slots 822, 824 closest to the link 802 when the spin lock 800 is in the locked configuration, and the pins 826, 828 may be disposed adjacent to a second, opposite end of the slots 822, 824 when the spin lock 800 is in the unlocked configuration.

[0251] At least one biasing mechanism is operably coupled to the spin lock 800 to bias the first locking pin 806 and the second locking pin 808 radially outward toward the locked position. In one embodiment, the biasing mechanism is coupled to the link 802. However, in other embodiments such as those shown in the figures, respective biasing members 830, 832 such as coil springs are operably coupled to each of the first locking pin 806 and the second locking pin 808 and are operable to bias the first locking pin 806 and the second locking pin 808 to the first locked position.

[0252] In 840( Fig.72 ) is operably coupled to the spin lock 800. In the illustrated non-limiting embodiment, the link 802 includes a radially extending actuation tab 836, and the actuator 840 is coupled to the actuation tab 836 via a linkage mechanism or tension member 838. The application of force to the actuator 840 serves to rotate the link 802 about its axis X. This rotation applies force to the first and second locking pins 806, 808, thereby causing the locking pins 806, 808 to translate from the locked position to the unlocked position. While the locking pins 806, 808 are maintained in the unlocked position via the application of force to the actuator 840, the second base member 78 can translate relative to the first base member 74. In addition, the actuator 840 can be biased to a normal position in response to the removal of the force applied to the actuator 840. The actuator 840 can be located at any suitable location around the child safety seat 24, such as at the outer surface of the upright side member. Alternatively, the actuator 840 may be positioned at a support base, such as at the first base member 76 or the second base member 78 .

[0253] At least one base anchor member 104 can be fixedly connected to a portion of the second base member 78. For example, the base anchor member 104 can be part of the frame 80 and extend through an opening formed in the structural shell 82 (see Figure 2 ). Although the non-limiting embodiment shown includes a base anchor member 104 disposed at the base rear portion 72 of the support base 22 near the distal end 106 of the second base member 78, it should be understood that the base anchor member 104 can be disposed in any suitable location. The base anchor member 104 can be connected to a corresponding seat anchor member 108. In one embodiment, the seat anchor member 108 is located at the third base member 86. For example, the seat anchor member 108 can be disposed at the base member rear portion 90 so that the base anchor member 104 can be connected to the seat anchor member when the child safety seat 24 is connected to the third base member 86 in a forward-facing configuration. In the non-limiting embodiment shown, the seat anchor member 108 includes a wavy flange or groove that is complementary to the base anchor member 104. In other embodiments, the seat anchor member 108 can be disposed at the child safety seat 24. For example, at Fig.21B and 23 In the non-limiting embodiment of FIG. 1 , the seat anchor component 108 protrudes from the seat back portion 26 , such as from the outer surface 35 thereof.

[0254] As will be described in more detail below, the base anchor member 104 may also be connected to the seat anchor member 108 regardless of the tilt angle 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 connected 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 the seat anchor member 108 disposed at any location around the third base member 86 and / or the child safety seat 24.

[0255] Alternatively or additionally, the child safety seat 24 can be moved relative to at least a portion of the support base 22 when coupled to the support base 22 to adjust the deflection of the child safety seat 24. In an embodiment, the second base member 78 can be moved (e.g., translated) along a deflection path relative to the first base member 74 to control the deflection or recline of the child safety seat 24. Because the third base member 86 is coupled to the second base member 78, the third base member 86 and the child safety seat 24 connectable thereto can be moved in unison with the second base member 78 between a first position associated with, for example, an upright position of the child safety seat 24 and a second position associated with, for example, a reclined position of the child safety seat 24. However, it should be understood that both the first reclined position and the second reclined position can be positions arranged in a deflection, the positions having different degrees of deflection. In addition, embodiments in which the child safety seat 24 can be arranged in any of a plurality of reclined positions between the upright position and the reclined position are also contemplated herein.

[0256] In addition, the support base 22 may include a rearward tilt lock mechanism operable to selectively lock the second base member 78 and, therefore, the child safety seat 24 coupled thereto via the third base member 86, in one of a plurality of positions along the deflection path. An example of a rearward tilt lock mechanism 420 is shown in FIG. Figures 41 to 44B . As shown, the rearward tilt lock mechanism 420 includes a centrally located pivot link 422 that can rotate about an axis. As shown, the pivot link 422 can have two end segments 424 extending outwardly therefrom, such as disposed on opposite sides of the pivot link 422 relative to its axis of rotation. At least one rearward tilt pin 426, such as two rearward tilt pins, is connected to the pivot link 422. As shown, the rearward tilt pins 426 can extend from the pivot link 422 in opposite directions.

[0257] The plurality of rearward dump pins may be in a first locked position ( ) in which the second base member 78 cannot move relative to the first base member 74. Fig.42 , 43A , 44A) and wherein the second base member 78 and thus the child seat 24 rotatably coupled to the second base member 78 can freely move relative to the first base member 74 to adjust the second base member 78 and the child seat 24 to a second unlocked position ( Fig.43B and 44B). When each of the rearward tilt pins 426 is in the locked position, the second end 428 of the rearward tilt pin 426 is received in a corresponding lock opening 430 formed in a portion of the first base component 74, such as in a side wall of the first base component. When the rearward tilt pins 426 are in the second unlocked position, the second end 428 of the rearward tilt pin 426 is separated or disengaged from the lock opening 430, thereby allowing the second base component 78 and the child seat 24 to tilt or recline.

[0258] In one embodiment, a corresponding biasing member 432, such as a coil spring, is operably coupled to each of the rearward tilt pins 426 and is operable to bias the rearward tilt pins 426 to a first locked position. An actuator 434 is operably coupled to the rearward tilt lock mechanism 420. In the non-limiting embodiment shown, the pivot link 422 includes a radially extending actuation tab 436, and the actuator 434 is coupled to the actuation tab 436 via a linkage mechanism or a tension member 438. The application of force to the actuator 434 can be used to rotate the pivot link 422 around its axis. This rotation will apply force to the rearward tilt pin 426, thereby causing the rearward tilt pin 426 to translate from the locked position to the unlocked position. While the rearward tilt pin 426 is maintained in the unlocked position via the application of force to the actuator 434, the second base member 78 can translate relative to the first base member 74. The actuator 434 can be biased to a normal position in response to the removal of the force applied to the actuator 434. The biasing mechanism (not shown) may be coupled directly to the actuator 434, or alternatively, the biasing mechanism may be associated with an intermediate component, such as Fig.44A and 44B As shown in , the intermediate assembly is operable to engage the actuator 434 and transmit a biasing force thereto.

[0259] like Fig.42 As shown, the first base member 74 includes a plurality of lock openings 430, each lock opening being associated with a different deflection or recline of the child seat 24. The second base member 78 can thus be moved to a position in which the end 428 of the recline pin 426 is aligned with and configured to engage with a corresponding lock opening of the plurality of lock openings 430. It should be understood that the recline lock mechanism 420 shown and described herein is intended only as an example, and any mechanism suitable for selectively locking and unlocking the movement of the child seat 24 and / or the second base member 78 relative to the first base member 74 to adjust the deflection of the child seat 24 is within the scope of the present invention. In addition, the child safety seat 24 can be rotated relative to the support base between a forward-facing configuration and a rearward-facing configuration when the child seat is locked in any of the plurality of reclined positions.

[0260] Reference Figures 45 to 47In one embodiment, the support base 22 includes a seat belt tensioner 450. In the non-limiting embodiment shown, an opening 452 is formed in a base rear portion of the support base 22, such as the second base member 78, and the seat belt tensioner 450 is receivable within the opening 452. The profile of the seat belt tensioner 450 can be complementary to the profile of the opening 452 so that a substantial portion of the seat belt tensioner 450 can be receivable within the opening 452. A vehicle seat belt associated with the vehicle seat 10 can be positioned along a seat belt storage path defined between a surface of the base rear portion 72 of the support base 22 and the seat belt tensioner 450. In one embodiment, the seat belt tensioner 450 can be selectively movable relative to the support base 22 to adjust the tension applied to the vehicle seat belt 12 along the vehicle seat belt storage path. For example, the seat belt tensioner 450 can be configured to be in an open position ( Fig.45 and 46 ) and closed position ( Fig.38 ) pivots about at least one axis between the support base 22 and the vehicle seat 10 to selectively tension a portion of the vehicle seat belt 12 sandwiched between the seat belt tensioner 450 and the opening 452 to couple the support base 22 to the vehicle seat belt 12, thereby limiting movement of the support base 22 relative to the vehicle seat 10.

[0261] The seat belt tensioner locking mechanism 470 can be used to hold the seat belt tensioner 450 in a closed position. As shown, a portion of the seat belt tensioner 450, such as near its top end 456, includes a rigid shaft or pin 458. One or more slots 460 can be formed at a surface 462 of the seat belt tensioner 450 that faces the opening 452 and can extend to the shaft 458 to define a passage for accessing the shaft 458. At least one buckle 472 is arranged in the opening 452 at a position aligned with the slot 460 formed in the surface 462 and can be connected to the shaft 458. In one embodiment, each buckle 472 includes a movable part 474 and a fixed part 476. When the buckle 472 is opened ( Fig.46 ), the movable member 474 is arranged at a non-parallel angle relative to the fixed member 476. Therefore, the ends of the movable member 474 and the fixed member 476 are separated from each other and define an opening for receiving the shaft 458. When the buckle 472 is closed ( Fig.45 ), the movable member 474 rotates toward the fixed member 476. In the closed configuration, the movable member 474 can be oriented substantially parallel to the fixed member 476, and the distal ends of the movable member 474 and the fixed member 476 can overlap each other. Thus, when closed, the opening 478 defined between the movable member 474 and the fixed member 476 is substantially enclosed, thereby locking the shaft 458 in place relative to the buckle.

[0262] A biasing mechanism (not shown) may be associated with the movable member 474 of the buckle 472 and operable to bias the movable member 474 toward the closed position toward the fixed member 476. When the seat belt tensioner 450 is pivoted toward the opening 452 and the buckle 472, the shaft 458 may engage the forward facing surface 480 of the movable member 474. In the non-limiting embodiment shown, the forward facing surface 480 of the movable member 474 is contoured, such as angled, such that the engagement between the shaft 458 and the forward facing surface 480 pushes the movable member 474 away from the fixed member 476 against the bias of the biasing mechanism. Once the shaft 458 is beyond the forward facing surface 480, the bias will cause the movable member 474 to rotate toward the fixed member 476 such that the shaft 458 is enclosed within the opening 478.

[0263] The actuator 482 is operably coupled to the at least one buckle 472 to selectively open the at least one buckle 472 to release the seat belt tensioner 450. Although the actuator 482 is shown as being located proximate to the seat belt tensioner locking mechanism 470, it should be understood that embodiments in which the actuator 482 is located remote therefrom are also within the scope of the present invention. The actuator 482 is coupled to the seat belt tensioner 450 via a linkage mechanism 484 (see Fig.45 ) or other suitable connection is operably coupled to the movable member 474 of the at least one buckle 472. Thus, when a force is applied to the actuator 482, such as when the actuator 482 is pressed, for example, the force is transmitted to the movable member 474 via the linkage mechanism 484. The force resists the bias of the biasing mechanism, thereby separating the movable member 474 from the fixed member 476. In the disengaged or open position, the seat belt tensioner 450 can be moved away from the seat belt opening 452.

[0264] As indicated above, at least a portion of the child safety seat 24 may be removably connected to the third base member 86. In one embodiment, the seat pan portion 28 may be detachable from the third base member 86, such as from the base member seat portion 88 thereof. Figures 5 to 7 33, the base member seat portion 88 may include at least one upwardly protruding attachment member, such as extending from the surface 110 in a direction between its rearward and forward ends. Figures 5 to 7The non-limiting embodiment shown in Figures 3 and 33 includes a first attachment member 120 that is generally centrally arranged between the lateral sides of the base member seat portion 88. In addition, two substantially identical second attachment members 122 can be laterally spaced apart from the first side 124 and the second side 126 of the first attachment member 120, respectively. However, it should be understood that embodiments including a single attachment member and / or at least one attachment member arranged at another position around the base member seat portion 88 are also covered herein. Each attachment member 120, 122 can be formed into a tube, a strip, a block, or any other suitable shape. The one or more attachment members 120, 122 can be formed of a suitably rigid material and can be fixedly attached to the base member seat portion 88, or alternatively, can be integrally formed with the body of the third base member 86.

[0265] like Figure 6 , 7 , 36A and 36B, at least one positioning feature 130, such as a groove, is formed in one or more surfaces of the seat pan portion 28 of the child safety seat 24, such as a bottom surface 132 of the seat pan portion 28 configured to engage the upper surface 110 of the seat pan portion 28. Each seat positioning feature 130 can be complementary in size and / or shape to a corresponding one of the attachment members 120, 122 so that the attachment member can be received therein. This alignment and / or engagement between the attachment members 120, 122 and the seat positioning feature 130 properly positions the seat pan portion 28 adjacent to the base member seat portion 88.

[0266] In one embodiment, the seat pan portion 28 of the child safety seat 24 is loosely positioned around the support base, such as around the base member seat portion 88. As used herein, the term "loosely positioned" describes an embodiment in which the seat pan portion is simply arranged in contact with the support base but the seat pan portion is not otherwise connected thereto. Therefore, in this loosely positioned configuration, a user can easily separate the seat pan portion 28 from the support base 22 simply by lifting and / or rotating the seat pan portion 28 away from the third base member 86. The weight of the passenger may be sufficient to restrain the undesirable separation of the seat pan portion 28 from the third base member 86. In other embodiments, the seat pan portion 28 may be coupled or attached to the third base member 86 via a booster locking mechanism. In such embodiments, the booster locking mechanism prevents the undesirable separation of the seat pan portion 28 from the third base member 86. Therefore, the booster locking mechanism must be deactivated, for example, by disconnecting the corresponding portion of the booster locking mechanism before the seat pan portion 28 is separated from the third base member 86.

[0267] Fig.342. An example of a height-enhancing member locking mechanism 370 is shown in FIG. As shown, the height-enhancing member locking mechanism 370 includes at least one locking member 372 movably mounted to the seat pan portion 28. In the non-limiting embodiment shown, the locking member 372 is pivotally mounted to the underside of the seat pan portion 28, such as near the first seat side member 56 or the second seat side member 60. The locking member 372 includes an elongated body 374 having an engagement feature 376 disposed at a first end thereof and an actuation surface 378 disposed, for example, near a second end thereof. The engagement feature 376 may be oriented at a non-parallel angle to the body. A biasing member (not shown), such as a torsion spring, is operably coupled to the locking member 372 and is operable to bias the locking member 372 toward a first locked position (shown). In the locked position, the engagement feature 376 extending from the body 374 is disposed in contact with or abuts against a surface of the third base member 86.

[0268] The actuator 380 is operably coupled to the locking member 372. Fig.34 And further reference Fig.35 , the actuator 380 includes a handle 382 disposed at an outer surface of the child safety seat 24. In the non-limiting embodiment shown, the handle 382 is disposed at an outer surface of the seat bottom portion 28, such as at one of the first seat side component 56 or the second seat side component 60. The handle 382 can be directly or indirectly coupled to the locking member 372. As shown, the actuating member 384 can extend from the surface of the handle 382 toward the interior of the seat bottom portion 28. The actuating member 384 can be aligned and positioned with the actuating surface 378 of the locking member 372.

[0269] To operate the actuator 380 to unlock the seat pan portion 28 from the third base member 86, the user applies a force F2 to the handle 382. In one embodiment, the user is configured to push or translate the handle 382 inward. However, embodiments in which the handle 352 is moved in another manner, such as pulling or rotating outward, are also within the scope of the present invention. This movement of the handle 382 moves the actuation member 384 to engage with the actuation surface 378 and transmit force to the actuation surface. The force applied to the actuation surface 378 resists the bias 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 or disengaged from the third base member 86. Although Fig.34372, it should be understood that embodiments including multiple locking components are within the scope of the present invention. For example, the locking component 372 can be arranged adjacent to each of the first seat side component 56 or the second seat side component 60. In such embodiments, a single actuator can be operably coupled to the multiple locking components 372, or alternatively, a corresponding actuator 380 can be associated with the corresponding locking component 372.

[0270] refer to Figures 48 to 49B , another embodiment of a booster locking mechanism 500 is shown. The booster locking mechanism 500 includes at least one locking member 502 pivotally mounted to the seat pan portion 28, such as pivotally mounted to the underside of the seat pan portion 28. In one embodiment, the locking member 502 is a latch plate. Similar to Fig.34 and 35 , the latch plate 502 includes an engagement member 504 disposed at a first end thereof and a release member 506 disposed, for example, near a second end thereof. A recess 508 may be defined between the engagement member 504 and the release member 506. A biasing mechanism 510, such as a torsion spring, may be operably coupled to the latch plate 502. In one embodiment, the biasing mechanism 510 is operable to move toward a first locked position ( Fig.49A ) biases the latch plate 502. In the first locked position, a pin or shaft 512 disposed at the third base member 86 is received within the recess 508 and / or engaged by the engagement member 504 of the latch plate 502.

[0271] The seat pan portion 28 further includes an actuator 514 operatively coupled to the heightening member locking mechanism 500. In the illustrated non-limiting embodiment, the actuator 514 is a release handle disposed at an outer surface of the seat pan portion 28, such as an upper surface thereof. The actuator 514 may be pivotally mounted to the seat pan portion 28. The actuator 514 may be substantially flush with the upper surface of the seat pan portion 28 when not actuated. In one embodiment, the rotation axis of the actuator is parallel to the rotation axis of the latch plate 502. A portion of the actuator 514, such as a distal end 516 thereof, is configured to contact the release member 506 of the latch plate 502. In response to lifting the actuator 514, the actuator 514 pivots about its axis so that the distal end 516 engages the release member 506 of the latch plate 502 and applies force to the release member. This engagement causes the latch plate 502 to rotate in a direction opposite to the biasing force of the biasing mechanism 510. This movement of the latch plate 502 disengages the pin 512 and the engagement 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.

[0272] In some embodiments, the seat back portion 26 of the child safety seat 24 is not separable from the support base 22. However, in other embodiments, both the seat pan portion 28 and the seat back portion 26 are removable from the third base member 86. More specifically, the seat pan portion 28 can be removably connected to the base member seat portion 88, and the seat back portion 26 can be removably connected to the base member rear portion 90 of the third base member 86. In addition, the seat pan portion 28 can be separated from the seat back portion 26, so that the seat pan portion 28 and the seat back portion 26 can be independently separated from the third base member 86.

[0273] exist Figures 8 to 12 In the non-limiting embodiment shown in , the seat back portion 26 includes at least one and in some embodiments, multiple seat interlocking features 140, such as grooves, recesses, or openings. The base component rear portion 90 can similarly include at least one base interlocking feature 142, such as a flange, rib, or other protrusion, which is configured to engage, be received within, or rest against a corresponding seat interlocking feature 140. This engagement between the at least one seat interlocking feature 140 and the at least one base interlocking feature 142 properly positions the base component rear portion 90 of the third base component 86 relative to the adjacent seat back portion 26.

[0274] exist Fig.12 In the non-limiting embodiment shown in , the base interlock feature 142 is smaller than the corresponding seat interlock feature 140. Therefore, the base interlock feature 142 can be received within the first portion of the seat interlock feature 140, and can then be moved (e.g., slid) to the second portion of the seat interlock feature 140. Within the second portion of the seat interlock feature 140, the base interlock feature 142 can engage multiple surfaces of the seat back portion 26, such as the upper end 144 of the seat interlock feature 140, thereby limiting undesirable separation of the base interlock feature 142 from the seat interlock feature 140.

[0275] In one embodiment, the base member rear portion 90 includes at least one base interlock feature 142 protruding from near the bottom thereof, and the seat back portion 26 includes at least one seat interlock feature 140, such as an opening, into which the base interlock feature can be received. Figures 13A to 15, the at least one base interlock feature 142 can extend through the seat back portion 26 such that at least a distal end 146 of the base interlock feature 142 is disposed generally adjacent to the upright support surface 30. The seat back portion 26 can include an engagement feature 150 that is movable relative to the upright support surface 30 to selectively engage an adjacent base interlock feature 142. In the non-limiting embodiment shown, the engagement feature 150 is a pin lock that includes a handle 152 and a pin 154 extending from the handle 152. The base interlock feature 142 includes an opening or through hole 148, and the free end of the pin 154 can be received within the opening 148 to couple the base interlock feature 142, and thus the third base component 86, to the seat back portion 26.

[0276] The pin lock 150 can translate into engagement with the base interlock feature 142. For example, the pin lock 150 can be configured to be in an unlocked position ( Fig.13A ) and locked position ( Fig. 13B ). In the unlocked position, the distal or free end of the pin 154 is spaced inwardly from the base interlock feature 142 and in the locked position, the pin 154 is received within the opening 148 of the base interlock feature 142. In some embodiments, the pin lock 150 can also rotate about an axis to maintain the pin lock 150 in the locked position. As shown, the pin lock 150 can be rotated out of the plane of the upright support surface 30 between a first position in which the handle 152 extends at a non-parallel angle to the adjacent upright support surface 30 and a second position in which the handle 152 is substantially parallel to the adjacent upright support surface 30. The upright support surface 30 of the seat back portion 26 can have one or more grooves or recesses 156 formed therein, so that when the pin 154 is the locked position and the handle 152 is in the second position, at least a portion of the handle 152 is disposed in the recess 156. Alternatively or in addition, the pin 154 of the pin lock 150 can be disposed in a recess 156, such as the same recess or a different recess. By this configuration, the handle 152 and / or the pin 154 can be positioned at a position that avoids or minimizes contact with the back of the passenger. In addition, the handle 152 can include a tab, flange or other feature 158 that is configured to engage or abut a corresponding surface of the recess 156 when the handle 152 is arranged in the second position. This engagement can prevent undesired rotation of the handle 152 from the second position.

[0277] While the translation and rotation of the pin lock 150 are described as occurring separately or sequentially, in other embodiments, the rotation of the pin lock 150 from the first position to the second position about the axis X causes the pin lock 150 to simultaneously translate along the axis X between the unlocked position and the locked position. For example, a user may apply a downward force to the handle 152, thereby causing the handle 152 to rotate about the axis X, and as the handle 152 rotates downward, the pin lock 150 slides laterally into engagement with the through hole 148 of the base interlock feature 142. It should be understood that the engagement features 150 and the interface with the corresponding base interlock features 142 as illustrated and described herein are intended only as examples, and any suitable mechanism for removably coupling the third base component 86 to the seat back portion is contemplated herein.

[0278] A portion of the child safety seat system 20, such as the support base 22, may include a harness 200 operable to secure a child in the 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 non-limiting embodiment shown, the harness 200 is attached to and positioned adjacent to the third base member 86. Figures 5 to 8 The harness best shown in FIG. 1 may include multiple harness straps, including but not limited to shoulder straps, a waist belt, and a crotch strap.

[0279] In one embodiment, the harness 200 includes a crotch strap that is generally positionable between the legs of the passenger and has a piece of webbing 202 and a buckle 204 at its distal end (also located on the upper side of the harness). Figures 21A to 21C 200). The sling 200 may further include a first strap 206 and a second strap 208, each of which has at least one piece of webbing and a latch 210 configured to be selectively fastened to the buckle 204. The latch 210 may be releasably fixed or fastened to the buckle 204 to secure the child in the child safety seat 24. Each of the first strap 206 and the second strap 208 may have a leg strap portion that can be positioned above the child's legs and a shoulder strap portion that can be positioned above the child's shoulders. In one embodiment, the leg strap portion and the shoulder strap portion of each strap 206, 208 are separate pieces of webbing coupled to the latch 210. In another embodiment, the leg strap portion and the shoulder strap portion are integrally formed via a single piece of webbing. In such embodiments, the latch 210 is movable relative to the webbing piece, and the portion of the webbing arranged on the first side of the latch 210 forms the leg strap portion and the portion of the webbing on the second side of the latch 210 forms the shoulder strap portion.

[0280] In one embodiment, one end (not shown) of the webbing 202 of the crotch strap is attached to a portion of the support base 22, such as the third base member 86. In addition, the webbing 202 can extend through at least one attachment member, such as the first attachment member 120. As shown, the first attachment member 120 can define a recess 220 that is configured to receive and store the crotch strap when the harness 200 is not being used to restrain a child in the child safety seat 24. For example, the crotch strap can be stowed in the recess 220 when the child safety seat 24 is used as a booster seat without the harness 200.

[0281] One end of the leg strap portion and / or one end of the shoulder strap portion of each strap 206, 208 can be attached to a portion of the support base 22, such as the third base member 86. The ends of the leg strap portion and the shoulder strap portion can be coupled to the third base member 86 at a location disposed below the upper surface 110 of the third base member. In the non-limiting embodiment shown, the end of each leg strap portion extends through a corresponding attachment member, such as a corresponding second attachment member 122.

[0282] The child safety seat 24 can have one or more openings formed therein to receive the straps of the harness 200 when the child safety seat 24 is mounted to the support base 22. For example, the shoulder strap portion of each strap 206, 208 can extend through a corresponding slot (not shown) formed in the upright support surface 30, or alternatively in a portion of the headrest 46. In such embodiments, the slot can extend to an edge of the upright support surface 30, such as the top edge, or to an edge of the headrest to provide a path for mounting the shoulder strap portion. In embodiments where the shoulder strap portion extends through a slot formed in the headrest 46, the harness is operably coupled to the headrest 46.

[0283] exist Figure 6 , 7 In the non-limiting embodiment shown in FIGS. 21A and 21A, the seat pan portion 28 of the child safety seat 24 has a first opening 230 formed in a seat positioning feature 130 configured to overlap with the first attachment member 120. The first opening 230 is sized to receive the buckle 204 of the crotch strap. Similarly, a slit 232 is associated with each corresponding seat positioning feature 130 configured to engage the second attachment member 122. As shown, the slit 232 forms an opening at each seat positioning feature 130 and can extend beyond the seat positioning feature 130 in at least one direction to an edge of the seat pan portion 28, such as the rear portion 54.

[0284] During installation of the seat pan portion 28 of the child safety seat 24 to the support base 22, the leg strap portion of each of the first strap 206 and the second strap 208 is fed into the slot 232 and pulled into alignment with one of the seat locating features 130. The buckle 204 of the crotch strap can similarly be passed through a corresponding opening 230 formed in the corresponding seat locating feature 130. With each of the leg strap portion and the crotch strap accessible at the seat pan portion 28 of the seat support surface 50, the seat pan portion 28 can then be lowered into position about the third base member 86 so that the seat locating features 130 are aligned and engaged with the corresponding first attachment features 120 and second attachment features 122. Once in position, the seat pan portion 28 can be coupled to the third base member 86 and / or the seat back portion 26 as previously described. It should be understood that the harness 200 shown and described herein is intended to be an example only and that harnesses having any suitable configuration are contemplated herein.

[0285] The seat pan portion 28 may include at least one cup holder 520. Figures 50 to 52 In the illustrated non-limiting embodiment, the seat pan portion 28 includes a first cup holder 520 positioned at the first seat side member 56 and a second cup holder 520 positioned at the second seat side member 60. Although two cup holders 520 are shown, it should be understood that embodiments having only a single cup holder are also within the scope of the present invention. The cup holder 520 can be arranged in front of a slot 66 formed in the seat side members 56, 60 configured to receive and position the leg belt portion of the vehicle seat belt. In an embodiment, the cup holder 520 is positioned to provide sufficient seating space for the seat occupant while also providing sufficient clearance relative to the support base 22 of the child restraint system 20. As shown, the soft goods 522 can be configured to be tucked under a portion of the cup holder 520, such as under an edge 524 of the cup holder 520.

[0286] The cup holder 520 can be moved relative to the seat pan portion 28, and in some embodiments can be removed relative to the seat pan portion. In one embodiment, the cup holder 520 includes a resilient or flexible snap-on finger 526 extending from a bottom 528 of the cup holder. The flexible snap-on finger 526 is configured to engage a protrusion 530 located at the interior of the seat pan portion 28 to restrict the separation of the cup holder 520 from the seat pan portion 28. A flexible snap-on finger button 532 can be formed at the outer surface of the seat pan portion 28 adjacent to a portion of the surface of the flexible snap-on finger 526. Application of a force to the flexible snap-on finger button 532 moves the flexible snap-on finger 526 out of engagement with the protrusion 530 to allow separation of the cup holder 520 from the seat pan portion 28. The removability of the cup holder 520 improves them while also providing a finished appearance with the adjacent textile 522.

[0287] refer to Figures 73 to 75B , shows in more detail an example of a seat pan portion 28 having a removable cup holder 900 similar to the cup holder 520. As shown, an actuation mechanism 902 associated with the cup holder 900 is operable to selectively release the cup holder 900 from the seat pan portion 28. In the non-limiting embodiment shown, the actuation mechanism 902 can be removably coupled to the seat pan portion 28. As shown, the actuation mechanism 902 can be received within an opening 904 formed in the seat pan portion 28, such as directly below the cup holder 900. The actuation mechanism 902 can include a body 906 having a first end 908 positionable at an exterior 910 of the seat pan portion 28, such as at the seat side members 56, 60. The body 906 further includes a slot 912, and a flexible snap-on finger or other feature 914 extending the cup holder 900 can be received within the slot 912. The body 906 may further define a surface 916 that may be engaged by an end 918 of the feature 914 to limit separation of the cup holder 900 from the seat pan portion 28. In one embodiment, a biasing structure 920 is mounted within the interior of the seat pan portion 28 adjacent the opening 904 and may be operably coupled to the actuation mechanism 902, such as to a second end 922 thereof. The biasing structure 920 may be operable to bias the actuation mechanism 902 to an engaged position.

[0288] To disengage the cup holder 90 from the seat pan portion 28, the user applies a force to the first end 908 of the actuation mechanism 902. The force opposes the biasing force of the biasing mechanism 920, thereby causing the body 906 to translate within the opening 904 formed in the seat pan portion 28. As a result of this translation, the surface 916 moves out of engagement with the flexible snap fingers 914, such that the flexible snap fingers 914 are disposed within the slots 912 formed in the body 906. When the actuation mechanism 902 is in this disengaged position, the cup holder 900 can be separated from or mounted relative to the seat pan portion 28. As shown, when the cup holder 900 is not mounted about the seat pan portion 28, the actuation mechanism 902 can be removed from the seat pan portion 28.

[0289] Reference Figures 16 to 19 , showing various usage configurations of the child safety seat system 20 . Fig.16 1 shows a configuration for use of the child safety seat system 20 associated with an infant or child having a weight of up to approximately 40 pounds. As shown, the child safety seat 24 is connected to the support base 22 and faces rearward. In the infant configuration, the child is restrained in the child safety seat 24 using a harness 200 integral to the child safety seat system 20, and the support base 22 may be mounted to the vehicle seat 10 using an integrated latch system or using the vehicle seat belt. Fig.17Another configuration of the child safety seat system 20 shown in FIG. 1 is associated with use with toddlers or children older than two years of age or weighing between approximately twenty-five and sixty-five pounds. In this toddler configuration, the child safety seat 24 is connected to the support base 22 and faces forward. Similar to the infant configuration, in the toddler configuration, the child is restrained within the child safety seat 24 using the harness 200 of the child safety seat system 20, and the support base 22 may be mounted to the vehicle seat 10 using an integrated latch system or using the vehicle seat belt.

[0290] In other embodiments, the child safety seat 24 can be configured as a booster seat. For example, in embodiments where the seat pan portion 28 and the seat back portion 26 can be separated from the support base 22, such as Fig.18 , the child safety seat 24 faces forward and may be arranged in direct contact with the vehicle seat 10. In this high back booster configuration, the child safety seat system 20 is intended for use with a child having a weight between about forty pounds and about one hundred pounds. In addition, the child is restrained within the child safety seat 24 using the vehicle seat belt. Although the child safety seat 24 is shown in a high back booster configuration in which the support base 22 is not present, it should be understood that the child safety seat 24 may also be used in a booster configuration when the child safety seat system 20 is attached to the support base 22. In such embodiments, the child is restrained within the child safety seat 24 using the vehicle seat belt and without the harness 200.

[0291] In the non-backrest height-boosting configuration ( Fig.19 ), only the seat pan portion 28 of the child safety seat 24 faces forward and is in direct contact with the vehicle seat. The support base 22 and the seat back portion 26 of the child safety seat 24 are not present in the non-back booster configuration. In this configuration, the child safety seat 24 can be suitable for use by a child having a weight between about forty pounds and about one hundred and twenty pounds, and the child is restrained relative to the seat pan portion 28 by the vehicle seat belt.

[0292] refer to Figures 36A to 37B , the seat pan portion 28 can include a stability foot 390. As shown, the stability foot 390 can be positioned at or adjacent to the bottom surface 132 of the seat pan portion 28. The stability foot 390 can be movable relative to the body of the seat pan portion 28. For example, the stowable stability foot 390 can be in a first stowed configuration ( Fig.36A , 37A ) and the second extended configuration ( Fig.36B , 37B). In the first stowed configuration, a front surface 392 of the stability foot 390 is substantially aligned with an adjacent surface 394 of the main body, and in the second, extended configuration, the front surface 392 of the stability foot 390 is axially offset from the adjacent surface 394 of the main body. In embodiments where the main body slopes 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 stability foot 390 may be substantially aligned with the front edge 52 when in the stowed configuration. In the extended configuration, a bottom surface 396 of the stability foot 390 (in addition to the bottom surface 132 of the seat pan portion 28) may be positioned in contact with a support surface, such as the vehicle seat 10. Thus, in the extended configuration, the footprint of the seat pan portion 28 is expanded, thereby increasing the stability of the seat pan portion 28.

[0293] exist Fig.53 In other embodiments shown in , the seat pan portion 28 can have multiple separate stability feet 540. For example, a first stability foot 540 can be disposed near the first seat side component 56, and a second stability foot 540 can be disposed near the second seat side component 60. In embodiments including multiple discrete stability feet, the stability feet 540 can, but need not, have the same configuration. Similar to the previous embodiments, the multiple stability feet 540 can be moved between a stowed configuration and an extended configuration relative to the seat pan portion 28. In embodiments including multiple stability feet 540, the stability feet 540 can operate in unison, or alternatively can move independently of each other.

[0294] refer to Figure 54 to 5 9, showing an example of a stability foot 540 in more detail. In the stowed configuration, the at least one stability foot 540 may be at least partially, and in some embodiments, completely, disposed within the interior of the seat pan portion 28 (see Fig.55B In one embodiment, the at least one stability leg 540 has an inclined or angled front surface 542, and when the stability leg 540 is in the retracted configuration, the front surface 52 is parallel or substantially parallel to the angled front surface 544 of the seat pan portion 28. In the extended configuration, the one or more stability legs 540 protrude beyond a surface of the seat pan portion 28, such as the front surface 544. Fig.55A, the bottom 546 of the stability foot 540 is spaced apart from and substantially aligned with the bottom 548 of the seat pan portion 28 when in the extended configuration. Thus, when the seat pan portion 28 is used independently of the remainder of the child seat 24, both the bottom 546 of the stability foot 540 and the bottom 548 of the seat pan portion 28 can be positioned on a support surface, such as the vehicle seat 10. In one embodiment, when the at least one stability foot 540 is in the extended configuration, the seat pan portion 28 has a different angle of inclination relative to the vehicle seat than when the at least one stability foot is in the stowed configuration.

[0295] In one embodiment, the at least one stability foot 540 can rotate between a stowed configuration and an extended configuration. However, embodiments in which the at least one stability foot 540 can translate or move in another manner are also covered herein. In the illustrated non-limiting embodiment, each stability foot 540 of the seat pan portion 28 is operably coupled to a corresponding retractor 550 via a linkage 552. As shown, the retractor 550 can include an engagement member 554 and a foot member 556 arranged at an angle relative to each other. Although the foot member 556 and the engagement member 554 are shown as being substantially perpendicular to each other, embodiments in which the members 554, 556 are separated at another angle are also within the scope of the present invention. The retractor 550 can rotate relative to the seat pan portion 28 about an axis. The linkage 552 is pivotally coupled to one end of the foot member 554 and pivotally coupled to a portion of the stability foot 540, such as near the rear portion 558 of the stability foot 540.

[0296] The biasing mechanism 560 is operably coupled to the stability leg 540 to bias the stability leg 540 to the extended configuration. In the non-limiting embodiment shown, the biasing mechanism 560 is connected to the retractor 550; however, embodiments that include the biasing mechanism 560 in another suitable location are also contemplated herein. Upon separation of the seat pan portion 28 from the third base member 86 of the child seat 24, the biasing force of the biasing mechanism 560 will cause the corresponding stability leg 540 to automatically transition from the retracted configuration to the extended configuration. Thus, if the seat pan portion 28 is not attached to the child seat 24, the stability leg 540 extends to enhance the stability of the seat pan portion.

[0297] The stability foot 540 can be automatically retracted in response to the seat pan portion 28 being connected to the child seat 24, such as to the third base component 86. In one embodiment, the third base component 86 includes a booster receiver 562 ( Fig.57). When the seat pan portion 28 is attached to the third base member 86, the booster receiver 562 engages the corresponding retractor 550. This engagement applies a force to the retractor 550, causing the retractor 550 to rotate about its axis, such as toward the front of the seat pan portion 28. This rotation of the retractor 550 drives a corresponding rotation of the stability foot 540 in the opposite direction. Therefore, as the retractor 550 is rotated by the booster receiver 562, the stability foot 540 rotates in the opposite direction via the linkage 552, such as toward the interior of the seat pan portion 28 and the retractor 550. The retractor 550 remains in this rotated position while the seat pan portion 28 remains coupled to the third base member 86. Upon separation of the seat pan portion 28 from the third base member 86, the biasing force acting on the retractor 550 will cause the retractor 550 to rotate to drive the corresponding stability foot 540 forward to the extended configuration.

[0298] refer to Figures 58 to 59B In another embodiment, rather than being operably coupled via a linkage, the foot member 554 of the retractor 550 may be secured directly to the stability foot 540 (via pin 564). The operation of this configuration is substantially the same as Figures 54 to 57 As previously described, engagement with the booster receiver 562 drives the retractor 550, and therefore the stability foot 540 coupled to the retractor 550, to the retracted configuration. Once the seat pan portion 28 is separated from the third base member 86, the biasing force of the biasing mechanism 560 acting on the retractor 550 will automatically rotate the retractor 550, thereby driving the stability foot 540 forward to the extended configuration.

[0299] Reference Figures 60A to 60BIn one embodiment, at least a portion of the metal structural frame of the support base 22 is formed of aluminum. For example, at least one of the rigid frame 80 of the second base member 78 and the spin bracket 92 of the third base member 86 can be formed of aluminum. However, it should be understood that while a portion of the structural frame of the support base 22 can be formed of aluminum, another portion of the structural frame can be formed of a different material, such as steel. In the non-limiting embodiment shown in the accompanying drawings, both the rigid frame 80 and the spin bracket 92 are formed of a first material, such as aluminum. In such an embodiment, one or more components disposed at the interface between the rigid frame 80 and the spin bracket 92 are formed of a second material, such as steel. As shown, the bottom spin cover 99 disposed between the rigid frame 80 and the spin bracket 92 is formed of a steel material. Similarly, the base anchoring component 104 disposed near one end of the rigid frame 80 and the seat anchoring component 108 disposed at a corresponding position of the spin bracket 92 can be formed of a steel material. The use of this material combination may require additional bolting. However, it should be understood that embodiments in which the structural frame of the support base 22 is formed from another material or another combination of materials including a metal alloy having sufficient strength for application are also within the scope of the present invention.

[0300] The head restraint 46 of the child seat 24 as described herein can be moved between a retracted position and an extended position relative to the upright support surface 30 of the child seat 24, thereby allowing adjustment based on the size of the child positioned in the child seat 24. The locking mechanism 600 operable to selectively lock the head restraint 46 in a position relative to the child seat 24 generally includes a component associated with the head restraint 46 and receivable within one of a plurality of openings of a slot 602 formed in a channel 604 at or adjacent to the upright support surface 30. In one embodiment, a portion of the spin bracket 92 forms a channel 604 including a plurality of slots 602 that define respective positions of the head restraint 46.

[0301] In embodiments where the spin bracket 92 is formed of an aluminum material, existing locking mechanisms may not be suitable for interacting with aluminum components. In the illustrated non-limiting embodiment, the locking mechanism 600 includes a first lock component 610 operably coupled to a second lock component 612. The first lock component 610 can be positioned relative to the headrest 46 in a locked position ( Fig.62A , 62B , 63A, 64A) and an unlocked position ( Fig.63B and 64B) between the first and second lock components 610, such as being rotatable about an axis. The second lock component 612 may also be movable relative to the headrest 46. For example, the second lock component 612 may be rotatable about an axis between a disengaged position and an engaged position. In the non-limiting embodiment shown, the type and / or direction of movement of the second lock component 612 is different from the type and / or direction of movement of the first lock component 610. As shown, the rotation axis of the second lock component 612 is arranged at a non-parallel angle to the rotation axis of the first lock component 610. For example, the axes may be perpendicular to each other. However, any suitable configuration of the first lock component 610 and the second lock component 612 is within the scope of the present invention. For example, a biasing mechanism 614 of a torsion or spring may be operably coupled to the first lock component 610 and may bias the first lock component 610 to engage with an adjacent slot 602.

[0302] The locking mechanism 600 may be part of an actuation mechanism 620 associated with movement of the headrest 46. In one embodiment, the actuation mechanism 620 includes at least one link member 622. Although only a single link member 622 is shown, it should be understood that in some embodiments, the actuation mechanism 620 may include a plurality of link members 622, such as a link member associated with each channel 604 of the slot 602 and a corresponding locking mechanism 600. In the non-limiting embodiment shown, a portion of the second lock member 612 may be received within an opening 624 formed in the link member 622 when the actuation mechanism 620 is not actuated.

[0303] The actuation mechanism 620 additionally includes an actuator 626, such as a handle, disposed on the exterior of the headrest 46 for user access. In the non-limiting embodiment shown, the actuator 626 is disposed at or near the top of the headrest 46. The 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 can be connected to the actuator 626, or in some embodiments, be integrally formed with the actuator.

[0304] The first lock component 610 disengages from the corresponding slot 602 in response to operation of the actuator 626, such as via application of force to the actuator 626. Once disengaged, the headrest 46 can move relative to the child seat 24. When a user applies force to the actuator 626, the force is transmitted to the at least one link component 622, causing the at least one link component 622 to translate relative to the headrest 46. As the link component 622 translates, a surface of the link component 622 engages the second lock component 612 and applies force to the second lock component, causing the second lock component 612 to rotate about its axis toward the first lock component 610. As it rotates, the second lock component 612 engages a portion of the first lock component 610. The force transmitted to the first lock component 610 by the second lock component 612 resists the biasing force of the biasing mechanism 614, thereby causing the first lock component 610 to rotate out of engagement with the slot 602.

[0305] When the actuator 626 is released, the biasing force of the biasing mechanism 614 will rotate the first lock component 610 into engagement with the corresponding slot 602. The rotation of the first lock component 610 will drive a similar rotation of the second lock component 612. As the second lock component 612 rotates about its axis, it will apply a force to a corresponding portion of the link component 622, causing the link component 622 to translate downward so that the second lock component 612 is received within the opening 624 of the link component 622.

[0306] Yet another embodiment of a head restraint locking mechanism 600 associated with the head restraint 46 is Figures 65 to 69B As shown in the figure, the locking mechanism 600 includes a single lock component 640, which has a first or ramp engagement component 642 and a second or slot engagement component 644. The lock component 640 can be arranged in direct contact with a portion of a link component 646. In the non-limiting embodiment shown, the link component 646 includes an opening 648 and a ramp surface 650 extending from the opening 648. However, it should be understood that embodiments in which the link component 646 does not include an opening 648 are also within the scope of the present invention. The biasing mechanism 652 is operably connected to the lock component 640 to bias the slot engagement component 644 into engagement with a slot associated with the position of the headrest 46, such as the slot 602 (see Figures 69A to 69B ).

[0307] As previously described, the link member 646 can be operably coupled to an actuator 654 accessible by a user, and in some embodiments, is integrally formed with the actuator. In response to the application of force to the actuator 654, the link member 646 translates relative to the headrest 46. As the link member 646 translates, the ramp engagement member 642 slides along the ramp surface 650. As the slope of the ramp surface 650 increases, this engagement causes the lock member 640 to pivot about its longitudinal axis. This rotation of the lock member 640 resists the biasing force of the biasing mechanism 652 and moves the slot engagement member 644 out of the corresponding slot 602 ( Fig.67B , 68B , 69B). Figures 68A to 69B As shown in , the disengagement slot 656 can be formed in a portion of the headrest 46 that is aligned with the slot engagement member, such as the headrest housing 47. Therefore, when the slot engagement member 644 is rotated out of engagement with the slot 602 associated with the child seat, the slot engagement member 644 is received in the disengagement slot 656 of the headrest 46. When the actuator 654 is released, gravity can cause the link member 646 to move downward relative to the headrest 46, so that the ramp surface 650 is disengaged from the ramp engagement surface. In addition, the biasing force of the biasing mechanism 652 will rotate the lock member 640 back to engage with the corresponding slot 602 to lock the headrest to the slot in a position. However, it should be understood that in some embodiments, the biasing force of the biasing mechanism 652 can be sufficient to move the ramp surface 650 away from the ramp engagement member 642 and rotate the lock member 640 about its axis.
