[0217] This document provides a detailed description of one or more embodiments of the disclosed apparatus and methods by way of example and not limitation, with reference to the accompanying drawings.

[0218] Referring now to the accompanying drawings, various examples of a child safety seat system 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 detachably attached to the vehicle seat 10 (see...). Figure 1 (and 20), the fixing is, for example, via a latch or anchoring mechanism not shown in the figure. This latch or anchoring system, which is often used, is sometimes referred to as a “lower anchor and tether for children,” for example, a latch system. Alternatively or additionally, the support base 22 may be removably secured to the vehicle seat 10 via a vehicle seat belt associated with the vehicle seat 10.

[0219] The child safety seat system 20 further includes a child safety seat 24 associated with a support base 22. In one embodiment, the child safety seat 24 is detachably attached to the support base 22, thereby allowing the child safety seat 24 to be separated from the support base 22. Alternatively, at least a portion of the support base 22 and the child safety seat 24 may be permanently connected or attached together, as will be described in more detail below. As used herein, the term "permanently connected" refers to embodiments 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.

[0220] The child safety seat 24 includes a seat back portion 26 and a seat base portion 28 arranged at an angle relative to the seat back portion 26. The seat base portion 28 may, but does not need to, be configured to be removably coupled to the seat back portion 26. In the non-limiting embodiment shown, the seat back portion 26 includes a seat back with an upright support surface 30, which is generally face 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 arranged at a first side 38 of the upright support surface 30, and a second upright side member 40 may be arranged 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 the 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 substantially orthogonally to the upright support surface 30, or alternatively, may extend from it 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 that accommodates the upper body of a child.

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

[0222] exist Figures 21A to 23In the non-limiting embodiment shown, the seat back portion 26 is an assembly including a seat back 27, from which the upright support surface 30 and the first upright side member 36 and the second upright side member 40 extend at an angle as previously described. A separate back cover or seat back housing 29 may be positioned in contact with the rearward-facing surface 31 of the seat back 27. In the non-limiting embodiment shown, the seat back housing 29 has a size and shape complementary to the seat back 27, such that the seat back housing 29 overlaps the entire rearward-facing surface 31 of the seat back 27. However, embodiments in which the seat back housing 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 this invention. In such embodiments, the seat back housing 29 is formed of a first material, such as plastic or composite material, and the seat back 27 may be formed of a different second material, such as polystyrene or high-density foam. Furthermore, textiles (not shown) may be attached to the inward-facing surface of the seat back 27 to provide cushioning for a child sitting in the backrest area.

[0223] Continue to refer to Figures 21A to 23 In the illustrated non-limiting embodiment, the 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, with a length approximately equal to the distance between the top 32 and bottom 34 of the upright support surface 30, and a width approximately equal to the distance between the first side 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, it may extend beyond the upright support surface 30, for example, in an overlapping arrangement with one or both of the first upright side member 36 and the second upright side member 40.

[0224] Regardless of the construction of the seat back portion 26, in a non-limiting embodiment, one or more shock absorbers or side impact chambers 37, designed to absorb forces in the event of an accident or collision, can be arranged on the outer surface 35 of the seat back portion 26. While a single impact chamber 37... Figures 21A to 23As shown, but it should be understood, embodiments having multiple impact chambers 37 are within the scope of this invention. As shown, the at least one impact chamber 37 may 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 may be arranged vertically positioned above the support base 22. Furthermore, when the child safety seat system 20 is mounted around the vehicle seat 10, the at least one impact chamber is arranged without contact with the vehicle seat 10. However, embodiments including impact chambers 37 alternatively or separately arranged in another location are also covered herein. In the non-limiting embodiments 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. Thus, the at least one impact chamber 37 may 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, for example, generally aligned with the upright support surface 30, or only on one side of the outer surface, for example, aligned with one of the upright side members 36, 40, are also covered herein.

[0225] In the illustrated non-limiting embodiment, the seat back portion 26 of the child safety seat 24 includes a headrest 46. The headrest 46 may be attached to the seat back portion 26, integral with the seat back, or removably coupled thereto. The headrest 46 may be fixed, or in some embodiments, it may be configured to move relative to the upright support surface 30. For example, the headrest 46 may be configured to translate relative to the upright support surface 30 between a retracted position and an extended position, thereby allowing adjustment based on the size of the child positioned within 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 covered herein.

[0226] refer to Figure 5 , 6In one embodiment, as shown in 24A to 24C, the headrest 46 includes a body identified by 300, the body 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 in which the head of a child positioned within the child safety seat 24 is received. The first head-side component 304 and the second head-side component 308 may extend substantially orthogonally to the head support surface 302, or alternatively, may extend from it at another angle, for example, an angle greater than 90°. At least one of the first head-side component 304 and the second head-side component 308 may have the same or different angles relative to the head support surface 302 as the corresponding one of the first upright side component 36 and the second upright side component 40.

[0227] In one embodiment, such as Figures 24A to 24C As shown, the headrest 46 is a body comprising 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 therefrom at an angle as described. A second portion 314, comprising a headrest cover or panel, can be positioned in contact with the rear-facing surface (not shown) of the first portion 312. In a non-limiting embodiment shown, the second portion 314 has a size and shape complementary to the first portion 312, such that the second portion 314 substantially overlaps the entire rear-facing surface of the first portion 312. In such embodiments, the second portion 314 may be a structural shell formed of a first material, such as plastic, and the first portion 312 may be formed of a different second material, such as polystyrene or high-density foam. Textiles (not shown) may be arranged on 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 within the channel 316 to attach the textile to the headrest 46. However, any suitable component for attaching textiles to the headrest 46 is covered herein.

[0228] The headrest 46 may include at least one shoulder strap guide 320, having an opening 322 for receiving a vehicle seatbelt. The shoulder strap 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, the at least one shoulder strap guide 320 can be aligned with a portion of the body 300 and mounted as an extension of said portion. For example, at least one shoulder strap guide 320 can be positioned on the bottom surface of one or both of the first head-side component 304 and the second head-side component 308. The shoulder strap guide 320 can have a shape complementary to an adjacent portion of the body 300, such that the shoulder strap guide is flush with the body and defines a portion of the outline of the headrest 46. The at least one shoulder strap guide 320 can be permanently attached to the body 300, or alternatively, can be detachably connected to it. In the non-limiting embodiment shown, the shoulder strap guide 320 is attached to the body 300, for example, at a location between the first portion 312 and the second portion 314, using one or more fasteners. However, it should be understood that any suitable component for removably connecting the shoulder strap guide 320 to the body 300 of the headrest 46 at any location is within the scope of this invention.

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

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

[0231] In the non-limiting embodiment shown, each seat side component 56, 60 has a slot 66 formed therein, which is configured to act as a leg strap guide during at least one usage 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 the leg strap portion of the vehicle restraint or individual restraint seat belt to secure the child within the child safety seat 24. As will be described in more detail, the rotational configuration and / or tilting of the child safety seat 24 can be adjusted when the child safety seat 24 is connected to the support base 22.

[0232] 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 as the first booster portion and the seat base portion 28 can be considered as the second booster portion. However, embodiments in which the seat base portion 28 is the first booster portion and the seat back portion 26 is the second booster portion are also covered herein. The first booster portion may, but does not need to, be configured to be removably connected to the second booster portion. Figure 20A and 20B In the non-limiting embodiment shown, the seat back portion 26 includes at least one seat back engagement feature 67, and the seat base portion 28 includes at least one seat base engagement feature 68 that can selectively engage with a corresponding seat back engagement feature. As shown, the seat back engagement feature 67 may be a protrusion extending from near the second end 34, and the seat base engagement feature 68 may be a corresponding recess or opening formed in the surface of the seat base portion 28 and aligned with the protrusion. Thus, the protrusion can be received within the recess to attach the seat back portion 26 to the seat base portion 28. However, embodiments in which the seat base engagement feature 68 is a protrusion and the seat back engagement feature 67 is a recess are also covered herein. Furthermore, other suitable mechanisms for removably attaching the seat back portion 26 to the seat base portion 28 are also within the scope of this invention.

[0233] 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...). Figure 1 For example, suitable materials for manufacturing 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 formed by separate components that are removable or permanently connected together.

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

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

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

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

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

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

[0240] Locking pin 336 can be in a first locked position in which the child safety seat 24 cannot rotate relative to the support base 22. Figure 28AThe child safety seat 24 is in a second unlocked position where it can rotate freely relative to the support base 22. Figure 28B The child safety seat 24 can be switched between the locking pins 336 and, therefore, the spinlock 330, when in the locked position, the second opposite end 340 of the locking pin 336 is received within the corresponding locking section 342, for example, in a recess or opening formed in a portion of the support base 22. When the locking pin 336 and, therefore, the spinlock 330, is in the second unlocked position, the second end 340 of the locking pin 336 separates from the locking section 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 locking sections 342 are formed in the second base member 78. However, embodiments in which the plurality of locking sections 342 are formed in the first base member 74 or another suitable component are also covered 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.

[0241] Continue to refer to Figure 28A and 28B And further reference Figures 29 to 32B At least one actuator 350 is operatively coupled to at least one of the locking pins 336. In the illustrated non-limiting embodiment, multiple actuators are operatively coupled to the spinlock 330. As shown, a first actuator 350a is operatively coupled to a first locking pin 336 and a second actuator 350b is operatively coupled to a second locking pin 336. Each actuator 350a, 350b can be operated independently or individually to change the locking pin 336 from a locked position to an unlocked position. Alternatively or additionally, the first actuator 350a and the second actuator 350b can be operated simultaneously to change the locking pin 336 from a locked position to an unlocked position.

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

[0243] In the non-limiting embodiment shown, the drive member 356 has an angled slot 362 formed therein, and a pin 364 extending through an opening 366 formed in the connecting rod 360, for example near one end, 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 connecting rod 360 relative to the drive member 356 applies a force to the tensioning member 354. Figure 31 As shown, a portion of the drive component 356, the connecting rod 360, and the tensioning member 354 may be embedded within the seat back portion 26, for example, between the seat back 27 and the seat back housing 29.

[0244] In order to operate actuator 350a to unlock spinlock 330, the user applies force F1 to handle 352. Figure 32A In one embodiment, the user operates the handle 352 to rotate forward. However, embodiments in which the handle 352 moves in another manner, such as translating inward, pushing, or pulling outward, are also within the scope of this invention. This movement of the handle causes the drive member 356 to rotate about its axis, such that the pin 364 of the engaging link 360 moves upward within the slot 362 (see...). Figure 32B Therefore, in response to the force applied to the handle 352, a force is applied to the corresponding locking pin 336 in the opposite direction to the bias of the biasing member. 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 connected to the link 332, rotation of the link 332 via the first locking pin 336 causes a similar inward movement of the second locking pin 336. This inward movement disengages the second ends 340 of both locking pins 336 from the corresponding locking sections 342 of the support base 22. With the actuators 350a, 350b operated and the locking pins 336 disengaged from the locking sections 342, the user can then rotate the child safety seat 24 relative to the support base 22 to the desired rotation configuration.

[0245] Once the child safety seat 24 has reached the desired rotational configuration, the user releases actuators 350a and 350b. Upon release of actuators 350a and 350b, the biasing force of the biasing member causes link 332 to rotate and locking pin 336 to move outward (e.g., translate) into engagement with the corresponding locking segment 342 associated with the rotational configuration of the child safety seat 24. This outward movement, applied to tension member 354, causes engaging link 360 to translate relative to slot 362, and drive member 356 to rotate about its axis back to the unactuated position. It should be understood that the spinlock 330 shown and described herein is intended only as an example, and any suitable configuration is within the scope of this invention.

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

[0247] As shown, the central portion 402 may include at least one engaging slot 404, such as a pair of engaging slots. At least one locking pin 406 may be secured to the central portion 402. In the illustrated non-limiting embodiment, the pair of locking pins 406 are movably coupled to the pair of engaging slots 404, respectively. As shown, the locking pins 406 may extend outward from the central portion 402 in opposite directions.

[0248] Locking pin 406 can be in a first locked position in which the child safety seat 24 cannot be rotated relative to the support base 22. Figure 39A The child safety seat 24 is in a second unlocked position where it can rotate freely relative to the support base 22. Figure 39B The child safety seat 24 can be switched between the locking pins 406 and, consequently, the spin lock 400, when in the locked position. 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 housed within a corresponding locking section (not shown) formed in a portion of the support base 22. When the locking pin 406, and therefore the spin lock 400, is in the second unlocked position, the distal end 408 of the locking pin 406 disengages from the locking section, thereby allowing the child safety seat 24 to rotate relative to the support base 22.

[0249] The actuator 410 is operably connected to the central portion 402. Figure 40 The spinlock 400 is operable to switch between a locked position and an unlocked position. In a non-limiting embodiment, the actuator is shown 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 spinlock is arranged in another location, such as around the child seat 24 or even around the support base 22, are also covered herein. When operated, the actuator 410 applies force to the central portion 402. As shown, the engagement slot 404 formed in the central portion 402 is arranged at a non-parallel angle relative to the direction of movement of the central portion 402. Therefore, the locking pin 406 is configured to translate inwardly when the locking pin 406 moves within the engagement slot 404 in response to the actuator 410 applying force to the central portion 402.

[0250] exist Figures 71A to 72Another embodiment of a spinlock 800 is shown. Similar to previous embodiments, the spinlock 800 includes a centrally positioned link 802 rotatable about an axis X. The link 802 can be mounted to a support base 22 via bolts or other suitable fasteners. As shown, the link 802 may have two end segments 804 extending outward therefrom, for example, positioned on opposite sides of the link 802 relative to the axis of rotation X. A plurality of locking pins 806, 808 may be connected to the link 802. Unlike the previously described embodiments in which two locking pins may 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 may be generally rectangular in shape, such that a first end 810 and a second end 812 of the first locking pin 808 are coaxial. A first end 810 of the first locking pin 806 can be connected to an end segment 804 of the connecting rod 802, and a second end 812 of the first locking pin 808 extends outward toward the outer periphery of the support base 22. The second locking pin 808 may include a first segment 814 having a generally curved or arcuate profile and a second segment 816 having a rectangular configuration, connected to or integrally formed with the first segment 816. For example, a first end 818 of the second locking pin 808 formed at the first arcuate segment 814 can be connected to the end segment 804 of the connecting rod 802, and a second end 820 of the second locking pin 808 disposed at the second segment 816 can extend radially outward from the connecting rod 802. As shown, the second segments 816 of the first locking pin 806 and the second locking pin 808 can be coaxial. Furthermore, this axis of the first locking pin 806 and the second segments 816 of the second locking pin 808 can be spaced apart from or offset from the axis of rotation X of the connecting rod 802, and therefore do not intersect with it.

[0251] The first locking pin 806 and the second locking pin 808 are in a first locked position in which the child safety seat 24 cannot be rotated relative to the support base 22. Figure 71A The child safety seat 24 is in a second unlocked position where it can rotate freely relative to the support base 22. Figure 71B The child safety seat 24 moves between the base and the support base 22. When in the locked position, the second ends 812 and 820 of the locking pins 806 and 808 are housed in corresponding locking sections (not shown) formed in a portion of the support base 22. When the locking pins 806 and 808, and therefore the spin lock 800, are in the second unlocked position, the second ends 812 and 820 of the locking pins 806 and 808 separate from the locking sections, thereby allowing the child safety seat 24 to rotate relative to the support base 22.

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

[0253] At least one biasing mechanism is operably coupled to the spinlock 800 to radially outwardly bias the first locking pin 806 and the second locking pin 808 toward a locked position. In one embodiment, the biasing mechanism is coupled to a link 802. However, in other embodiments, such as those shown in the figures, corresponding biasing components 830, 832, such as helical 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 a first locked position.

[0254] In 840 ( Figure 72 The actuator, schematically shown at ( ), is operably coupled to the spinlock 800. In the illustrated non-limiting embodiment, the link 802 includes a radially extending actuating tab 836, and the actuator 840 is coupled to the actuating tab 836 via a linkage mechanism or tension member 838. A force is applied to the actuator 840 to rotate the link 802 about its axis X. This rotation applies a force to the first locking pin 806 and the second locking pin 808, causing the locking pins 806, 808 to translate from a locked position to an unlocked position. While the locking pins 806, 808 are held in the unlocked position by the application of a force to the actuator 840, the second base member 78 can translate relative to the first base member 74. Furthermore, the actuator 840 can be biased to a normal position in response to the removal of a force applied to the actuator 840. The actuator 840 can be located at any suitable location around the child safety seat 24, such as on the outer surface of the upright side member. Alternatively, the actuator 840 may be positioned at a support base, such as at a first base component 76 or a second base component 78.

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

[0256] As will be described in more detail below, the base anchoring member 104 can be connected to the seat anchoring member 108 regardless of the tilt angle of the child safety seat 24 relative to the support base 22. This connection between the base anchoring member 104 and the seat anchoring member 108 stabilizes the seat back portion 26 of the child safety seat 24. In such embodiments, when the child safety seat 24 is in a rear-facing configuration, the base anchoring member 104 may not be able to be connected to the seat anchoring member 108. However, it should be understood that the base anchoring member 104 can be adapted for use with seat anchoring members 108 located anywhere on the third base member 86 and / or around the child safety seat 24.

[0257] Alternatively or additionally, the child safety seat 24, when coupled to the support base 22, can be moved relative to at least a portion of the support base 22 to adjust the tilt of the child safety seat 24. In one embodiment, the second base member 78 can be moved (e.g., translated) relative to the first base member 74 along a tilt path to control the tilt 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 to which it can be coupled can move in accordance with the second base member 78 between, for example, a first position associated with 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 with tilt, said positions having different degrees of tilt. Furthermore, 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 covered herein.

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

[0259] The plurality of rear tilt pins may be in a first locked position in which the second base component 78 is immobile relative to the first base component 74. Figure 42 , 43A , 44A) and the child seat 24, which is rotatably connected to the second base component 78, can move freely relative to the first base component 74 to adjust the second unlocked position of the tilt of the second base component 78 and the child seat 24. Figure 43B and 44BThe rear tilt pins 426 change position consistently between the two positions. When each of the tilt pins 426 is in the locked position, the second end 428 of the tilt pin 426 is received with a corresponding locking opening 430 formed in a portion of the first base member 74, for example, in a sidewall of the first base member. When the tilt pin 426 is in the second unlocked position, the second end 428 of the tilt pin 426 separates or disengages from the locking opening 430, thereby allowing the second base member 78 and the child seat 24 to tilt or recline.

[0260] In one embodiment, a corresponding biasing member 432, such as a coil spring, is operably coupled to each of the tilt pins 426 and operable to bias the tilt pin 426 to a first locked position. An actuator 434 is operably coupled to the tilt lock mechanism 420. In the illustrated non-limiting embodiment, the pivot link 422 includes a radially extending actuating tab 436, and the actuator 434 is coupled to the actuating tab 436 via a linkage mechanism or tension member 438. The application of a force to the actuator 434 can be used to rotate the pivot link 422 about its axis. This rotation will apply a force to the tilt pin 426, causing the tilt pin 426 to translate from the locked position to the unlocked position. While the tilt pin 426 is held in the unlocked position by the application of a 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) can be directly coupled to the actuator 434, or alternatively, the biasing mechanism can be associated with an intermediate component, such as... Figure 44A and 44B As shown, the intermediate component is operable to engage actuator 434 and transmit a bias force thereto.

[0261] like Figure 42 As shown, the first base component 74 includes a plurality of locking openings 430, each associated with a different tilt or recline of the child seat 24. The second base component 78 is thus movable to a position in which the end 428 of the tilt pin 426 is aligned with and configured to engage with a corresponding locking opening among the plurality of locking openings 430. It should be understood that the tilt locking mechanism 420 shown and described herein is intended only as an example, and any mechanism suitable for selectively locking and unlocking the child seat 24 and / or the movement of the second base component 78 relative to the first base component 74 to adjust the tilt of the child seat 24 is within the scope of this invention. Furthermore, the child safety seat 24 can rotate 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.

[0262] For reference Figures 45 to 47In one embodiment, the support base 22 includes a seatbelt tensioner 450. In the illustrated non-limiting embodiment, an opening 452 is formed in a rear portion of the base of the support base 22, such as in a second base member 78, and the seatbelt tensioner 450 is receptacle within the opening 452. The profile of the seatbelt tensioner 450 may be complementary to the profile of the opening 452, such that the substantially integral portion of the seatbelt tensioner 450 is receptacle within the opening 452. The vehicle seatbelt associated with the vehicle seat 10 may be positioned along a seatbelt retraction path defined between the surface of the rear portion 72 of the base of the support base 22 and the seatbelt tensioner 450. In one embodiment, the seatbelt tensioner 450 may be selectively movable relative to the support base 22 to adjust the tension applied to the vehicle seatbelt 12 along the vehicle seatbelt retraction path. For example, the seatbelt tensioner 450 may be configured in an open position ( Figure 45 and 46 ) and closing position ( Figure 38 The seat belt 12 is pivoted about at least one axis between the seat belt tensioner 450 and the opening 452 to selectively tension a portion of the vehicle seat belt 12 sandwiched between the seat belt tensioner 450 and the opening 452 to attach the support base 22 to the vehicle seat belt 12, thereby limiting the movement of the support base 22 relative to the vehicle seat 10.

[0263] A seatbelt tensioner locking mechanism 470 can be used to hold the seatbelt tensioner 450 in a closed position. As shown, a portion of the seatbelt tensioner 450, for example near its tip 456, includes a rigid shaft or pin 458. One or more slots 460 may be formed on the surface 462 of the seatbelt tensioner 450 facing the opening 452 and may extend to the shaft 458 to define a passage for access to the shaft 458. At least one buckle 472 is disposed within the opening 452 at a position aligned with the slot 460 formed in the surface 462 and is engageable with the shaft 458. In one embodiment, each buckle 472 includes a movable part 474 and a fixed part 476. When the buckle 472 is open ( Figure 46 When the movable part 474 is closed, it is arranged at a non-parallel angle relative to the fixed part 476. Therefore, the ends of the movable part 474 and the fixed part 476 are separated from each other and define an opening for receiving the shaft 458. When the retaining ring 472 is closed... Figure 45 When closed, the movable part 474 rotates toward the fixed part 476. In the closed configuration, the movable part 474 may be oriented substantially parallel to the fixed part 476, and the distal ends of the movable part 474 and the fixed part 476 may overlap each other. Therefore, when closed, the opening 478 defined between the movable part 474 and the fixed part 476 is substantially closed, thereby locking the shaft 458 in place relative to the retaining ring.

[0264] A biasing mechanism (not shown) may be associated with and operable to bias the movable part 474 toward the fixed part 476 in a closed position. When the seatbelt tensioner 450 pivots toward the opening 452 and the buckle 472, the shaft 458 may engage the forward-facing surface 480 of the movable part 474. In the non-limiting embodiment shown, the forward-facing surface 480 of the movable part 474 is wavy, for example, inclined, such that the engagement between the shaft 458 and the forward-facing surface 480 resists the biasing mechanism from pushing the movable part 474 away from the fixed part 476. Once the shaft 458 extends beyond the forward-facing surface 480, the biasing will cause the movable part 474 to rotate toward the fixed part 476, such that the shaft 458 is enclosed within the opening 478.

[0265] Actuator 482 is operably coupled to the at least one buckle 472 to selectively open the at least one buckle 472 to release the seatbelt tensioner 450. Although actuator 482 is shown positioned immediately adjacent to the seatbelt tensioner locking mechanism 470, it should be understood that embodiments in which actuator 482 is positioned away from its location are also within the scope of this invention. Actuator 482 is connected via linkage mechanism 484 (see...). Figure 45 (or other suitable connection) is operably coupled to the movable part 474 of the at least one buckle 472. Therefore, when a force is applied to the actuator 482, for example when the actuator 482 is pressed, the force is transmitted to the movable part 474 via the linkage mechanism 484. This force resists the biasing of the biasing mechanism, thereby separating the movable part 474 from the fixed part 476. In the disengaged or open position, the seatbelt tensioner 450 can move away from the seatbelt opening 452.

[0266] As indicated above, at least a portion of the child safety seat 24 can be removably connected to the third base component 86. In one embodiment, the seat base portion 28 is detachable from the third base component 86, for example, from its base component seat portion 88. (See reference...) Figures 5 to 7 33, the base component seat portion 88 may include at least one upwardly projecting attachment member, for example, extending from surface 110 in a direction between its rear end and front end. Figures 5 to 7The non-limiting embodiment shown in Figure 33 includes a first attachment member 120 generally centrally disposed between the lateral sides of the seat portion 88 of the base member. Furthermore, two substantially identical second attachment members 122 may be laterally spaced 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 disposed at another location around the seat portion 88 of the base member are also covered herein. Each attachment member 120, 122 may be formed as a tube, strip, block, or any other suitable shape. The one or more attachment members 120, 122 may be formed of a suitably rigid material and be securely attached to the seat portion 88 of the base member, or alternatively, may be integrally formed with the body of the third base member 86.

[0267] like Figure 6 , 7 As shown in 36A and 36B, at least one positioning feature 130, such as a recess, is formed in one or more surfaces of the seat base portion 28 of the child safety seat 24, for example, the bottom surface 132 of the seat base portion 28 configured to abut the upper surface 110 of the seat base portion 28. Each seat positioning feature 130 may be complementary in size and / or shape to a corresponding one of the attachment members 120, 122, such 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 base portion 28 adjacent to the base member seat portion 88.

[0268] In one embodiment, the seat base portion 28 of the child safety seat 24 is loosely positioned around a support base, such as around a base member seat portion 88. As used herein, the term "loosely positioned" describes an embodiment in which the seat base portion is simply arranged in contact with the support base but is not otherwise connected to it. Therefore, in this loosely positioned configuration, the user can easily and simply separate the seat base portion 28 from the support base 22 by lifting and / or rotating it away from the third base member 86. The weight of the passenger is sufficient to restrain undesirable separation of the seat base portion 28 from the third base member 86. In other embodiments, the seat base 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 undesirable separation of the seat base 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 base portion 28 is separated from the third base member 86.

[0269] Figure 34An example of a booster locking mechanism 370 is shown. As shown, the booster locking mechanism 370 includes at least one locking member 372 movably mounted to a seat base portion 28. In the non-limiting embodiment shown, the locking member 372 is pivotally mounted to the underside of the seat base portion 28, for example, near a first seat side member 56 or a 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 actuating 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 operable to bias the locking member 372 toward a first locking position (shown). In the locked position, the engagement feature 376 extending from the body 374 is disposed in contact with or abuts a surface of a third base member 86.

[0270] Actuator 380 is operably coupled to locking member 372. (Continue to the previous section) Figure 34 And further reference Figure 35 The actuator 380 includes a handle 382 disposed on the outer surface of the child safety seat 24. In the illustrated non-limiting embodiment, the handle 382 is disposed on the outer surface of the seat base portion 28, for example, at one of the first seat side member 56 or the second seat side member 60. The handle 382 may be directly or indirectly coupled to the locking member 372. As shown, the actuating member 384 may extend from the surface of the handle 382 toward the interior of the seat base portion 28. The actuating member 384 may be aligned and positioned with the actuating surface 378 of the locking member 372.

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

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

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

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

[0275] exist Figures 8 to 12 In the non-limiting embodiments shown, the seat back portion 26 includes at least one, and in some embodiments, multiple, seat interlocking features 140, such as recesses, indentations, or openings. The rear portion 90 of the base member may similarly include at least one base interlocking feature 142, such as a flange, rib, or other protrusion, configured to engage, be housed within, or abut 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 rear portion 90 of the base member 86 relative to the adjacent seat back portion 26.

[0276] exist Figure 12 In the non-limiting embodiment shown, the base interlock feature 142 is smaller than the corresponding seat interlock feature 140. Therefore, the base interlock feature 142 can be housed within a first portion of the seat interlock feature 140 and then movable (e.g., slidable) to a second portion of the seat interlock feature 140. Within the second portion of the seat interlock feature 140, the base interlock feature 142 can abut against 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.

[0277] In one embodiment, the rear portion 90 of the base component includes at least one base interlocking feature 142 projecting from near its bottom, and the seat back portion 26 includes at least one seat interlocking feature 140, such as an opening, into which the base interlocking feature can be received. Figures 13A to 15As shown, at least one base interlocking feature 142 may extend through the seat back portion 26 such that at least the distal end 146 of the base interlocking feature 142 is arranged substantially adjacent to the upright support surface 30. The seat back portion 26 may include an engagement feature 150 movable relative to the upright support surface 30 to selectively engage adjacent base interlocking features 142. In the non-limiting embodiment shown, the engagement feature 150 is a pin lock comprising a handle 152 and a pin 154 extending from the handle 152. The base interlocking feature 142 includes an opening or through-hole 148, and the free end of the pin 154 may be received within the opening 148 to connect the base interlocking feature 142, and thus the third base member 86, to the seat back portion 26.

[0278] The pin 150 can be translated to engage with the base interlocking feature 142. For example, the pin 150 can be configured in the unlocked position along axis X. Figure 13A ) and locked position ( Figure 13B The pin 154 slides between the base interlock feature 142 and the base interlock feature 142. 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 may also rotate about an axis to hold the pin lock 150 in the locked position. As shown, the pin lock 150 can rotate 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 extends at a substantially parallel angle to the adjacent upright support surface 30. The upright support surface 30 of the seat back portion 26 may have one or more grooves or recesses 156 formed therein, such that when the pin 154 is in the locked position and the handle 152 is in the second position, at least a portion of the handle 152 is disposed within the recess 156. Alternatively or additionally, the pin 154 of the pin lock 150 may be disposed within the recess 156, for example, the same recess or different recesses. With this configuration, the handle 152 and / or pin 154 can be positioned to avoid or minimize contact with the passenger's back. Furthermore, the handle 152 may include tabs, flanges, or other features 158 configured to engage or abut the corresponding surface of the recess 156 when the handle 152 is positioned in the second position. This engagement prevents undesirable rotation of the handle 152 from the second position.

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

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

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

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

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

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

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

[0286] During installation of the child safety seat 24 from the seat base portion 28 to the support base 22, the leg strap portions of each of the first strap 206 and the second strap 208 are fed into the slit 232 and pulled to align with one of the seat positioning features 130. The buckle 204 of the crotch strap can similarly pass through the corresponding opening 230 formed in the respective seat positioning feature 130. With each of the leg strap portions and the crotch strap accessible at the seat base portion 28 on the seat support surface 50, the seat base portion 28 can then be lowered into position around the third base member 86, such that the seat positioning feature 130 aligns and engages with the corresponding first attachment member 120 and the second attachment member 122. Once in place, the seat base 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 sling 200 shown and described herein is intended only as an example, and any suitable configuration of sling is covered herein.

[0287] The seat base portion 28 may include at least one cup holder 520. Figures 50 to 52 In the illustrated non-limiting embodiment, the seat base portion 28 includes a first cup holder 520 positioned at a first seat side member 56 and a second cup holder 520 positioned at a second seat side member 60. Although two cup holders 520 are shown, it should be understood that embodiments with only a single cup holder are also within the scope of this invention. The cup holder 520 may be arranged in front of a slot 66 formed in the seat side members 56, 60, which are configured to house and position the leg strap portion of a vehicle seat belt. In one 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, textile 522 may be configured to be sewn under a portion of the cup holder 520, for example, under the edge 524 of the cup holder 520.

[0288] The cup holder 520 is movable relative to the seat base portion 28 and, in some embodiments, removable relative to said seat base portion. In one embodiment, the cup holder 520 includes resilient or flexible hook-and-loop fingers 526 extending from the bottom 528 of the cup holder. The flexible hook-and-loop fingers 526 are configured to engage a protrusion 530 located inside the seat base portion 28 to restrain separation of the cup holder 520 from the seat base portion 28. A flexible hook-and-loop finger button 532 may be formed on the outer surface of the seat base portion 28 adjacent to a portion of the surface of the flexible hook-and-loop fingers 526. Applying force to the flexible hook-and-loop finger button 532 moves the flexible hook-and-loop fingers 526 away from engagement with the protrusion 530 to allow separation of the cup holder 520 from the seat base portion 28. The removability of the cup holders 520 improves their appearance while also providing a final look with the adjacent textile 522.

[0289] refer to Figures 73 to 75B An example of a seat base portion 28 having a removable cup holder 900 similar to a cup holder 520 is shown in more detail. As shown, an actuation mechanism 902 associated with the cup holder 900 is operable to selectively release the cup holder 900 from the seat base portion 28. In the non-limiting embodiment shown, the actuation mechanism 902 may be removably coupled to the seat base portion 28. As shown, the actuation mechanism 902 may be housed within an opening 904 formed in the seat base portion 28, for example, directly below the cup holder 900. The actuation mechanism 902 may include a body 906 having a first end 908 that can be positioned at an exterior 910 of the seat base portion 28, for example, at seat side members 56, 60. The body 906 further includes a slot 912, and flexible latching fingers or other features 914 extending from the cup holder 900 may be housed within the slot 912. The body 906 may further define a surface 916, which may be engaged by one end 918 of feature 914 to restrict separation of the cup holder 900 from the seat base portion 28. In one embodiment, a biasing structure 920 is mounted within the seat base portion 28, adjacent to opening 904, and may be operably coupled to an actuation mechanism 902, for example, to its second end 922. The biasing structure 920 is operable to bias the actuation mechanism 902 into an engaged position.

[0290] To detach the cup holder 90 from the seat base portion 28, the user applies a force to the first end 908 of the actuation mechanism 902. This force resists the biasing force of the biasing mechanism 920, causing the body 906 to translate within the opening 904 formed in the seat base portion 28. Due to this translation, the surface 916 moves away from engagement with the flexible hook-and-loop fingers 914, causing the flexible hook-and-loop fingers 914 to be positioned within a slot 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 base portion 28. As shown, when the cup holder 900 is not mounted around the seat base portion 28, the actuation mechanism 902 can be removed from the seat base portion 28.

[0291] For reference Figures 16 to 19 This shows various usage configurations of the child safety seat system 20. Figure 16 This illustrates the usage configuration of a child safety seat system 20 associated with an infant or child weighing up to approximately 40 pounds. As shown, the child safety seat 24 is attached to the support base 22 and faces rearward. In the infant configuration, the child is restrained within the child safety seat 24 using a harness 200 integrated with the child safety seat system 20, and the support base 22 can be mounted to the vehicle seat 10 using either an integrated latching system or the vehicle's seatbelt. Figure 17Another configuration of the child safety seat system 20 shown is associated with use by toddlers or children older than two years or weighing between approximately 25 and 65 pounds. In this toddler configuration, the child safety seat 24 is attached to the support base 22 and faces forward. Similar to the infant configuration, in the toddler configuration, the child is restrained within the child safety seat 24 using the harness 200 of the child safety seat system 20, and the support base 22 can be mounted to the vehicle seat 10 using either an integrated latching system or the vehicle seatbelt.

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

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

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

[0295] exist Figure 53 In other embodiments shown, the seat base portion 28 may have a plurality of individual stabilizing legs 540. For example, a first stabilizing leg 540 may be arranged near the first seat side member 56, and a second stabilizing leg 540 may be arranged near the second seat side member 60. In embodiments including a plurality of discrete stabilizing legs, the stabilizing legs 540 may, but need not, have the same configuration. Similar to previous embodiments, the plurality of stabilizing legs 540 may be movable relative to the seat base portion 28 between a folded configuration and an extended configuration. In embodiments including a plurality of stabilizing legs 540, the stabilizing legs 540 may operate uniformly, or alternatively may move independently of each other.

[0296] refer to Figures 54 to 5 9. An example of the stabilizing foot 540 is shown in more detail. In the retracted configuration, the at least one stabilizing foot 540 may be arranged at least partially, and in some embodiments completely, within the interior of the seat base portion 28 (see [reference]). Figure 55B In one embodiment, the at least one stabilizing leg 540 has an inclined or angled front surface 542, and when the stabilizing leg 540 is in a retracted configuration, the front surface 52 is parallel or substantially parallel to the angled front surface 544 of the seat base portion 28. In an extended configuration, the one or more stabilizing legs 540 protrude beyond the surface of the seat base portion 28, such as the front surface 544. Figure 55AIn the non-limiting embodiment shown, the bottom 546 of the stability leg 540 is spaced apart from and substantially aligned with the bottom 548 of the seat base portion 28 when in the extended configuration. Therefore, when the seat base portion 28 is used independently of the rest of the child seat 24, both the bottom 546 of the stability leg 540 and the bottom 548 of the seat base portion 28 can be positioned on a support surface, such as the vehicle seat 10. In one embodiment, the skew angle of the seat base portion 28 relative to the vehicle seat is different when the at least one stability leg 540 is in the extended configuration compared to the skew angle of the seat base portion 28 when the at least one stability leg is in the retracted configuration.

[0297] In one embodiment, the at least one stabilizing leg 540 is rotatable between a retracted configuration and an extended configuration. However, embodiments in which the at least one stabilizing leg 540 can translate or move in another manner are also covered herein. In the non-limiting embodiment shown, each stabilizing leg 540 of the seat base portion 28 is operatively coupled to a corresponding retractor 550 via a linkage mechanism 552. As shown, the retractor 550 may include an engagement member 554 and a leg member 556 arranged at an angle relative to each other. Although the leg member 556 and the engagement member 554 are shown as generally perpendicular to each other, embodiments in which the members 554, 556 are separated at another angle are also within the scope of this invention. The retractor 550 is rotatable about an axis relative to the seat base portion 28. The linkage mechanism 552 is pivotally coupled to one end of the leg member 554 and pivotally coupled to a portion of the stabilizing leg 540, for example, near the rear portion 558 of the stabilizing leg 540.

[0298] The biasing mechanism 560 is operatively coupled to the stability leg 540 to bias the stability leg 540 into an extended configuration. In the non-limiting embodiment shown, the biasing mechanism 560 is connected to the retractor 550; however, embodiments in which the biasing mechanism 560 is included in another suitable location are also covered herein. Upon separation of the seat base 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 a retracted configuration to an extended configuration. Thus, if the seat base portion 28 is not attached to the child seat 24, the stability leg 540 extends to enhance the stability of the seat base portion.

[0299] The stability support 540 can automatically retract in response to the seat base portion 28 being connected to the child seat 24, for example, to the third base component 86. In one embodiment, the third base component 86 includes a booster holder 562 arranged aligned with a corresponding retractor 550. Figure 57When the seat base portion 28 is attached to the third base member 86, the riser retractor 562 engages the corresponding retractor 550. This engagement applies a force to the retractor 550, causing it to rotate about its axis, for example, towards the front of the seat base portion 28. This rotation of the retractor 550 drives a corresponding rotation of the stabilizing leg 540 in the opposite direction. Therefore, as the retractor 550 is rotated by the riser retractor 562, the stabilizing leg 540 rotates in the opposite direction via the linkage mechanism 552, for example, towards the interior of the seat base portion 28 and the retractor 550. The retractor 550 remains in this rotated position while the seat base portion 28 remains connected to the third base member 86. After the seat base portion 28 separates from the third base member 86, a biasing force acting on the retractor 550 causes it to rotate, driving the corresponding stabilizing leg 540 forward into an extended configuration.

[0300] refer to Figures 58 to 59B In another embodiment, instead of being operably connected via a linkage mechanism, the support member 554 of the retractor 550 can be directly secured to the stabilizing support 540 (via pin 564). This configuration operates substantially the same as... Figures 54 to 57 The operation of the embodiment is as follows. As described above, engagement with the riser retractor 562 drives the retractor 550 and thus the stabilizing leg 540 connected to the retractor 550 into the retracted configuration. Once the seat base portion 28 is separated from the third base member 86, the biasing force acting on the biasing mechanism 560 of the retractor 550 will automatically rotate the retractor 550, thereby driving the stabilizing leg 540 forward into the extended configuration.

[0301] For reference Figures 60A to 60BIn one embodiment, at least a portion of the metal structural frame supporting the base 22 is formed of aluminum. For example, at least one of the rigid frame 80 of the second base component 78 and the spin bracket 92 of the third base component 86 may be formed of aluminum. However, it should be understood that while portions of the structural frame supporting the base 22 may be formed of aluminum, other portions of the structural frame may be formed of a different material, such as steel. In the non-limiting embodiment shown in the figures, both the rigid frame 80 and the spin bracket 92 are formed of a first material, such as aluminum. In such embodiments, 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 cap 99 disposed between the rigid frame 80 and the spin bracket 92 is formed of steel. 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 on the spin bracket 92 may be formed of steel. The use of this combination of materials may require additional bolted connections. However, it should be understood that embodiments in which the structural frame of the support base 22 is formed of another material or another combination of materials comprising a metal alloy having sufficient strength for application are also within the scope of this invention.

[0302] The headrest 46 of the child seat 24, as described herein, is movable relative to the upright support surface 30 of the child seat 24 between a retracted position and an extended position, thereby allowing adjustment based on the size of the child positioned within the child seat 24. A locking mechanism 600 operable to selectively lock the headrest 46 in its position relative to the child seat 24 typically includes a component associated with the headrest 46 and retractable within one of a plurality of openings in a slot 602 formed in or adjacent to the upright support surface 30. In one embodiment, a portion of the spin bracket 92 forms a channel 604 comprising a plurality of slots 602 that define corresponding positions of the headrest 46.

[0303] In embodiments where the spin bracket 92 is formed of aluminum, 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 locking member 610 operably coupled to the second locking member 612. The first locking member 610 can be positioned relative to the headrest 46 in a locked position where the first locking member 610 engages with the slot 602. Figure 62A , 62B (63A, 64A) and the unlocking position where the first locking component 610 is separated or disengaged from the plurality of slots 602 ( Figure 63B and 64BThe second locking member 612 can move relative to the headrest 46, for example, it can rotate about an axis. The second locking member 612 can also move relative to the headrest 46. For example, the second locking member 612 can rotate 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 locking member 612 differs from the type and / or direction of movement of the first locking member 610. As shown, the axis of rotation of the second locking member 612 is arranged at a non-parallel angle to the axis of rotation of the first locking member 610. For example, the axes can be perpendicular to each other. However, any suitable configuration of the first locking member 610 and the second locking member 612 is within the scope of this invention. For example, a biasing mechanism 614, such as a torque or spring, can be operably coupled to the first locking member 610 and can bias the first locking member 610 to engage with the adjacent slot 602.

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

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

[0306] The first locking member 610 disengages from the corresponding slot 602 in response to the operation of the actuator 626, for example, by applying force to the actuator 626. Once disengaged, the headrest 46 can move relative to the child seat 24. When the user applies force to the actuator 626, the force is transmitted to the at least one link member 622, causing the at least one link member 622 to translate relative to the headrest 46. As the link member 622 translates, its surface engages the second locking member 612 and applies force to the second locking member, causing the second locking member 612 to rotate about its axis toward the first locking member 610. During its rotation, the second locking member 612 engages a portion of the first locking member 610. The force transmitted from the second locking member 612 to the first locking member 610 resists the biasing force of the biasing mechanism 614, thereby causing the first locking member 610 to rotate and disengage from the slot 602.

[0307] When actuator 626 is released, the biasing force of biasing mechanism 614 causes the first locking member 610 to rotate and engage with the corresponding slot 602. The rotation of the first locking member 610 drives a similar rotation of the second locking member 612. As the second locking member 612 rotates about its axis, it applies a force to the corresponding portion of linking member 622, causing linking member 622 to translate downwards so that the second locking member 612 is received within opening 624 of linking member 622.

[0308] Another embodiment of the headrest locking mechanism 600 associated with headrest 46 is in Figures 65 to 69B As shown in the figure, the locking mechanism 600 includes a single locking member 640 having a first or ramp engagement member 642 and a second or slot engagement member 644. The locking member 640 may be arranged in direct contact with a portion of the linking member 646. In the non-limiting embodiment shown, the linking member 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 linking member 646 does not include an opening 648 are also within the scope of this invention. A biasing mechanism 652 is operably coupled to the locking member 640 to bias the slot engagement member 644 into engagement with a slot associated with the position of the headrest 46, such as slot 602 (see Figure 1). Figures 69A to 69B ).

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