[0065] 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.

[0066] For reference Figures 1 to 3 The illustration depicts a child safety seat 20 according to an embodiment. The child safety seat 20 can be, for example, via a latch or anchoring mechanism 12 (…). Figure 5 (shown in the middle) detachably secured to vehicle seat 10 ( Figure 7 This latching or anchoring system, often used, is sometimes referred to as a “lower anchor and tether for children,” for example, a latching system. Alternatively or additionally, as will be described in more detail below, the child safety seat 20 may be detachably secured to the vehicle seat 10 via a vehicle strap (not shown) associated with the vehicle seat 10.

[0067] A child safety seat 20 may include a seat base 22 and a rigid seat housing 24 coupled to the seat base 22 for accommodating a child. In one embodiment, the seat housing 24 is detachably attached to the seat base 22, thereby allowing the seat housing 24 to be separated from the seat base 22. Alternatively, the seat base 22 and the seat housing 24 may be permanently attached or attached together. As used herein, the term "permanently attached" refers to embodiments where it is not intended for the user to detach the seat housing 24 from the seat base 22.

[0068] The seat housing 24 may include a seat portion 26 and a backrest or upright portion 28 arranged at an angle relative to the seat portion 26. The seat portion 26 and the upright portion 28 may be detachably coupled, or alternatively, permanently coupled. In the illustrated non-limiting embodiment, the upright portion 28 and the seat portion 26 are integrally formed as a single unit. In another alternative aspect, the upright portion 28 may be rotatably connected to the seat portion 26, such that the upright portion 28 can tilt and recline relative to the seat portion 26.

[0069] As shown, the upright portion 28 of the seat housing 24 includes an upright support surface 30, which generally faces forward and extends from a first end or top 32 of the upright portion 28 to a second opposite end or bottom 34. 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 upright portion 28, respectively. As shown, the first upright side member 36 and the second upright side member 40 extend forward from the upright support surface 30. The first upright side member 36 and the second upright side member 40 may extend generally orthogonally to the upright support surface 30, or alternatively, may extend from it at another angle, for example, an angle greater than 90°. Therefore, the upright support surface 30 and the first upright side component 36 and the second upright side component 40 define the backrest area or upright support cavity 43, which accommodates the upper body of a child.

[0070] When the child safety seat 20 is installed in a vehicle, the side members 36, 40 can assist in the proper positioning of the vehicle harness. In some embodiments, each upright side member 36, 40 has an opening 44 formed therein. The opening 44 can be configured to receive a vehicle seat belt (not shown) to secure the child safety seat 20 to the vehicle seat in a forward-facing high-back configuration.

[0071] In the illustrated non-limiting embodiment, the upright portion 28 of the seat housing 24 includes a headrest 46. The headrest 46 is attached to or integral with the upright portion 28. 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 20.

[0072] Seat portion 26 includes a seat support surface 50, which generally faces upward and extends from a first end or front portion 52 of seat portion 26 to a second end or rear portion 54. A first seat side member 56 may be disposed at a first side 58 of seat support surface 50, and a second seat side member 60 may be disposed at a second opposite side 62 of seat support surface 50. The first seat side member 56 and the second seat side member 60 extend upward and form the left and right sides of seat portion 26. Seat support surface 50 and the first seat side member 56 and the second seat side member 60 define an area 64 in combination, within which at least a portion of a child's lower body can be accommodated.

[0073] 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 this is not required. 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 this is not required. In an embodiment, the first upright side member 36 and the first seat side member 56 are integrally formed, and the second upright side member 40 and the second seat side member 60 are integrally formed.

[0074] In the illustrated non-limiting embodiment, each seat side component 56, 60 has a slot 66 formed therein, the slot 66 being configured to act as a leg strap guide during at least one use mode of the child safety seat 20. The slot 66 may be configured to receive and position the leg strap portion of the vehicle restraints or a separate restraint strap to ensure that the child safety seat 20 is in a position such as… Figure 1 The child safety seat 20 is attached to the vehicle seat 10 in the forward-facing high-back configuration shown in the illustration.

[0075] refer to Figures 1 to 3In embodiments 5 to 6 and 9 to 10, at least one armrest 70 is arranged on the inner surface of the upright portion 28, for example within an upright support cavity 43 in which the child's upper body is accommodated. As shown, the inward surface 72 of at least one of the first upright side member 36 and the second upright side member 40 may have a non-flat configuration. For example, a cavity or recess 74 (in...) Figure 3 and 6 (Best shown in the diagram) may be formed in a portion of the inward surface 72. In the illustrated non-limiting embodiment, each upright side member 36, 40 has: a first end portion 76 disposed near a first end 32 of the upright support surface 30; a second end portion 78 disposed near a second end 34 of the upright support surface 30; and a central portion 80 disposed between the first end portion 76 and the second end portion 78. As shown, a cavity 74 may be formed in the central portion 80. In an embodiment, the inward surface at the central portion is an arcuate or curved surface 82 defining the cavity 74. The curved surface 82 may extend from approximately shoulder height to waist height of a child seated in a child safety seat. As shown, the curved surface 82 may be recessed and extend outward away from the plane defined by the inward surface 72 of the first end portion 76 or the second end portion 78. Therefore, the thickness of the first upright side member 36 and the second upright side member 40 can gradually decrease from the first end 84, which is positioned adjacent to the center portion 80 of the first end portion 76, toward the second end 86, which is arranged near the second end portion 78.

[0076] In one embodiment, within the cavity 74, an armrest 70 is arranged at the second end 86 of the curved surface 82. For example... Figure 3As best shown, the second end 86 of the curved surface 82 is not flush with the inward surface 72 of the second end portion 78. Specifically, the inward surface 72 adjacent to the second end 86 of the curved surface 82 may have a stepped configuration such that the inward surface 72 of the second end portion 78 is laterally offset from the second end 86 of the curved surface 82 toward the interior or child safety seat 20. This lateral offset, extending at the depth of the upright side members 36, 40 at said location, can form a shelf or support surface 88 suitable as an armrest 70. Alternatively, in embodiments, a separate component 90, such as a pad, is mounted in an arrangement overlapping this support surface 88. In embodiments where a pad or other component 90 is attached to the support surface 88 to form the armrest 70, the component 90 may protrude beyond the support surface 88 in at least one direction, for example, in front of the upright side members 36, 40, rearwardly into the opening 44 from the upright side members 36, 40, and / or inwardly from the support surface 88. Positioning the armrest 70 within the upright support cavity 43 provides a more ergonomic configuration for children seated in the child safety seat 20. Furthermore, arranging the armrest 70 vertically offset from and behind the slot 66 minimizes interference between the armrest and the positioning of the vehicle restraints within the slot 66.

[0077] like Figure 1 , 5 As best shown in 6, 8, and 9, in this embodiment, the child safety seat includes at least one light 92. The at least one light 92 is selectively operable to illuminate at least a portion of the upright support cavity 43 of the upright portion 28, in which the child's upper body is housed or directly in front of the upright support cavity 43. (See illustrations...) Figure 1 , 5 In the non-limiting embodiments illustrated in 6 and 8, at least one lamp 92 is positioned at the inward surface 72 of each of the upright side members 36, 40. Figure 9 and 10 In another embodiment illustrated, at least one lamp 92 is arranged on the forward surface of the central portion 80 of the side members 36, 40. Although Figure 1 , 5Figures 6 and 8 show a single lamp 92 with an elongated configuration, but it should be understood that embodiments with lamps 92 having other shapes and embodiments with multiple lamps are also within the scope of this disclosure. In embodiments, the lamp 92 may include various colors. For example, a child may choose between white light, blue light, yellow light, a combination of colored light, or another colored light. A child may choose between colors by actuating a switch or other mechanism for controlling a lamp (not shown) positioned, for example, on a curved surface 82. In embodiments where the upright side members 36, 40 include a cavity 74, at least one lamp 92 may be positioned within the cavity, for example adjacent to the front edge of the upright side members 36, 40. However, embodiments with lamps 92 arranged at another suitable location relative to the cavity 74 and / or the upright side members 36, 40 are also covered herein.

[0078] In one embodiment, the child seat 20 includes one or more lights 92 permanently attached thereto. However, in other embodiments, for example... Figure 10 As shown, at least one lamp 92 can be detachably attached to the child seat 20. Although only the lamps 92 located at the side parts 36, 40 of the child seat 20 are actually depicted as detachable, it should be understood that lamps located anywhere around the child seat 20 can be permanently or detachably attached to the child seat 20.

[0079] refer to Figures 11A to 12 An example of a detachable lamp 92 is illustrated in more detail below. In an embodiment, the lamp 92 may be integrated into an assembly 100, wherein the assembly 100 may be integrally and detachably connected to the child seat 20. The assembly 100 may be at least partially housed within a corresponding support or cavity 102 formed in a portion of the child seat 20 (e.g., within side members 36, 40). In such embodiments, the lamp 92 is positioned at a location of the assembly 100 that is visible from and / or not disposed within the cavity 102.

[0080] In the illustrated non-limiting embodiment, assembly 100 includes a housing 104 having a first end 106, a second end 108, and at least one sidewall 110 extending between the first end 106 and the second end 108. For selectively attaching assembly 100 to child seat 20, housing 104 may include a resilient or flexible member 112. As shown, flexible member 112 extends from sidewall 110 of housing 104 to the second end 108, such that a distal end 114 of flexible member 112 is exposed at the second end 108. Biasing of flexible member 112 radially outward from sidewall 110 pushes the distal end 114 of flexible member 112. In some embodiments, a flange or latch 116 projects outwardly from a central portion of flexible member 112.

[0081] refer to Figure 13When the assembly 100 is installed within the cavity 102 formed in the seat housing 24, a first end 106 of the housing 104 abuts the end of the cavity 102, and a second end 108 of the housing 104 is positioned near the adjacent external surface of the child seat 20, such as the forward surface of the side members 36, 40. During installation, the flexible member 112 is radially inwardly pressed against the sidewall 110 for its bias. In this compressed or compressed position, the latch 116 of the flexible member 112 is held outside a path that interferes with the internal surface 118 of the cavity 102. Once the assembly 100 is fully inserted, the flexible member 112 is released. Due to the bias, the distal end 114 of the flexible member 112 moves outward from the sidewall 110, thereby moving the latch to align with the adjacent internal surface 118 of the cavity 102. The latch surface contacts and abuts the internal surface 118 of the cavity 102, thereby restricting movement of the assembly 100 from the cavity 102. To remove assembly 100, flexible member 112 is compressed toward sidewall 110 to move latch 116 away from aligning it with internal surface 118. It should be understood that flexible member 112 and latch 116 illustrated and described herein are intended as examples only, and this document covers any suitable mechanism for selectively engaging the assembly to child seat 20, including, but not limited to, twist locks, friction fits, or threaded engagements.

[0082] The interior of housing 104 is typically hollow, allowing one or more additional components to be positioned therein. Figure 12 In the non-limiting embodiments illustrated herein, assembly 100 includes a power source 120 for powering a lamp 92 disposed within housing 104. Power source 120 may be replaceable, such as one or more batteries. In other embodiments, power source 120 may be rechargeable, such as a rechargeable battery. In such embodiments, power source 120 may be rechargeable after removal from assembly 100, or alternatively, may be recharged within assembly 100. In embodiments where power source 120 is recharged within assembly 100, assembly 100 includes a charging port 122 that includes, for example, a corresponding charging circuitry 124 formed at a first end 106 of housing 104. Thus, when assembly 100 is detached from child seat 20, a charger, such as a USB charger, may be connected to charging port 122 to recharge power source 120. Although assembly 100 is illustrated and described herein as including lamp 92, it should be understood that embodiments of assembly 100 without an embedded lamp are also covered herein. To be precise, as will be described in more detail below, assembly 100 can provide the power required for lamp 92 located away from assembly 100.

[0083] One or more lights 92 of the child seat 20 may operate automatically, for example, in response to an input. For example, the lights 92 may be activated or powered in response to the operation or application of a force to a button, switch, or other actuator located around the child seat 20. In a non-limiting embodiment illustrated in the figures, the assembly 100 includes a pressable button 126 located at a second end 108 of the housing 104, and applying force to the button 126 may selectively power the lights 92. In embodiments, one or more lights 92 may be operated, for example, via a timer or selectively powered for a predetermined period of time. For example, at least one light 92 may automatically turn off after 30 seconds, 45 seconds, one minute, or two minutes. In other embodiments, the same input may be used to power the lights 92, such as the button 126, or different inputs may be used to selectively depower the lights 92.

[0084] In an embodiment, one or more lights 92 may be operatively connected to one or more sensors (not shown). The one or more sensors may include, for example, a proximity sensor, a pressure sensor, or another sensor for sensing the proximity of the child seat 20 relative to a vehicle seat or stroller seat, or the position or movement of components of the child seat 20. The one or more sensors may be configured to transmit signals for activation and / or deactivation to the one or more lights 92.

[0085] refer to Figure 14 In an embodiment, when the assembly 100 is installed within the cavity 102, the power supply 120 embedded in the assembly 100 can be operatively connected to a plurality of lights 92 located at several different locations on the child seat 20, such as lights associated with the car seat belt path, or lights designed to assist in installing the child seat 20 within the vehicle. Thus, operation of the lights 92 embedded in the assembly 100, for example via button 126 or a sensor, can similarly power or depower one or more lights 92 associated with the child seat 20 and located remotely from the assembly 100. Furthermore, via the aforementioned connection to the plurality of lights 92, the power supply 120 of the assembly 100 can be used to provide power to the plurality of lights 92 when installed in the cavity 102.

[0086] In embodiments, assembly 100 may operate as a battery or power source for charging a portable device, including but not limited to a mobile phone, tablet, computer, or watch. Therefore, in some embodiments, assembly 100 may be considered a portable device charger. In embodiments where the assembly is a portable device charger, assembly 100 may (but may not) have a lamp 92. In such embodiments, the portable device may be electrically connected to power source 120 via a charging port formed in housing 104. The charging port for connecting the portable device to power source 120 may be the same charging port 122 for recharging power source 120, or may be separate from it. For example, in embodiments, charging port 122 for recharging power source 120 may be a USB Micro A or Micro B port, and the charging port for transferring power from power source 120 to the portable device may be a USB-A port. In other embodiments, housing 104 may include a plug or connector (not shown) retractable into the charging port of the portable device. In one embodiment, a charging port for powering the portable device may be located on the front or second end 108 of the housing 104. This location of the charging port allows the assembly 100 to charge the portable device not only when the assembly 100 is separated from the seat housing 24, but also when the assembly 100 is mounted around (e.g., inside) the seat housing 24.

[0087] In one embodiment, at least a portion of the seat base 22 is movable to adjust the tilt of the child safety seat 20. (See reference...) Figure 8 , 15A Up to 17, the seat base 22 includes a housing 200 and a support member 202 movable relative to the housing 200 between a plurality of positions, including, for example, a first position of tilting and a second position of reclining. However, it should be understood that both the first and second positions can be tilted, with different degrees of tilt. Furthermore, it should be understood that in some embodiments, the support member 202 may be arranged at one or more locations along a path of movement between the first and second positions to provide a greater degree of adjustability to the child safety seat 20. When the support member 202 is arranged in the first position, the support member 202 may be substantially or completely positioned within the interior of the housing 200. In the first position, the bottom 206 of the support member 202 may be substantially flush with the bottom surface 208 of the housing 200. In the second position, at least a portion of the support member 202, and in some embodiments, a substantial portion of the support member 202, protrudes beyond the bottom surface 208 of the housing 200. In the second position, the bottom 206 of the support member 202, rather than the bottom surface 208 of the seat, is configured to contact the vehicle seat.

[0088] Mechanism 203 can be used to adjust the tilt of the child safety seat 20 relative to the vehicle seat 10. Support member 202 can be selectively locked in a first position, a second position, or any position in between. (Reference) Figures 15A to 16B In the illustrated non-limiting embodiment, mechanism 203 includes a rack 210 mounted within the housing 200 and having a plurality of first teeth 212. A latch 214 having at least one second tooth 216 and, in some embodiments, a plurality of second teeth, is attached to support member 202. For example, latch 214 may be mounted on or near the upper surface of support member 202 (e.g., ...). Figure 15A As shown in the figure, it may be mounted in the support member 202 adjacent to the rack 210 (as shown in the figure). Figure 16A (As shown in the diagram). In each of the plurality of positions, at least one second tooth 216 engages with a plurality of first teeth 212 to selectively lock the support member 202 relative to the housing 200.

[0089] An actuator 220, operably coupled to the latch 214, may be located on the outer surface of the child safety seat 20, in a position accessible to the user. In an embodiment, the actuator 220 (see...) Figure 4 The actuator 220 is positioned adjacent to, for example, the upright side members 36, 40 of the backrest portion 28. Although the actuator 220 is illustrated at the backrest portion 28 of the seat housing 24, it should be understood that when the child safety seat 20 is installed in the vehicle seat, the actuator 220 may be located in any position easily accessible to the user. For example, in one aspect, the actuator 220 may be positioned on at least one of the first upright side member 36 and the second upright side member 40, and may extend into the corresponding opening 44. The user can access and actuate the actuator 220 by grasping the first upright side member 36 and the second upright side member 40 and passing their hands through the corresponding opening 44.

[0090] exist Figure 15A and 15BIn the illustrated non-limiting embodiment, the latch 214 is configured to translate relative to the rack 210 in response to operation of the actuator 220. A force F is transmitted to the latch 214, for example via a cable, linkage, or other flexible component 222, in response to operation of the actuator 220. This force F causes at least one second tooth 216 of the latch 214 to disengage and separate from a plurality of first teeth 212 of the rack 210. In this disengaged configuration, the support member 202 can be moved relative to the housing 200 to adjust the tilt angle of the child safety seat 20. In an embodiment, a biasing member 224 is operably coupled to the latch 214 and configured to bias the latch 214 into engagement with the rack 210. Therefore, once the force F is removed from the actuator 220, the biasing force of the biasing member 224 will cause the latch 214 to translate and at least one second tooth 216 to engage a plurality of first teeth 212, thereby locking the support member 202 in place relative to the housing 200.

[0091] exist Figure 16A and 16B In another embodiment shown, the latch 214 is configured to pivot relative to the latch 214 about axis P. In response to operation of the actuator 220, a force F transmitted to the latch 214 causes the latch 214 to pivot about axis P, thereby disengaging at least one second tooth 216 of the latch 214 from a plurality of first teeth 212 of the rack 210. In this disengaged configuration, the support member 202 can be moved relative to the housing 200 to adjust the tilt angle of the child safety seat 20. After the force is removed from the actuator 220, the biasing force of the biasing member 224 will cause the latch 214 to pivot toward the rack 210 about axis P. Although a vertically oriented spring 224 is illustrated, it should be understood that another biasing member 224, such as a torsion spring, capable of pivoting the latch 214 about its axis P is included herein. The biasing force of the biasing member 224 causes at least one second tooth 216 of the latch 214 to pivot to engage with a plurality of first teeth 212, thereby locking the support member 202 in place relative to the housing 200.

[0092] Actuator 220 can be configured to switch between an engaged position and a released position. In the engaged position, actuator 220 is not actuated, and latch 214 engages with rack 210 to lock support member 202 in place. In the released position, actuator 220 is actuated (e.g., compressed or rotated), latch 214 disengages from rack 210, and support member 202 can move relative to housing 200 to adjust the tilt of child safety seat 20.

[0093] For reference Figure 17An example of an actuator 220 according to an embodiment is illustrated in more detail. As shown, the actuator 220 includes a pivoting member 230 connected to a flexible member 222. The pivoting member 230 may have a slot 232 formed therein, and a pin or other member 234 extending from an inner surface of the seat housing 24 is received within the slot 232. Thus, the pivoting member 230 can translate relative to the pin 234. For example, a pressing button engagement member 236 protrudes through an opening in the seat housing 24. The engagement member 236 is operably coupled to the pivoting member 230. In an embodiment, the pivoting member 230 is configured to rotate about a pivot axis R relative to the engagement member 236.

[0094] To operate actuator 220, a force F is applied to engagement member 236 in a first direction. This force F causes engagement member 236 to translate inward into seat housing 24 in the same first direction, from an engaged position to a released position. As engagement member 236 translates, pivot member 230 rotates relative to engagement member 236 about pivot axis R. During this rotation, pivot member 230 is also configured to translate relative to seat housing 24, causing pin 234 to disengage from slot 232 ( Figure 17 The position near the first end of the pivot 230 is moved to a position near the second opposite end 238 of the slot 232. Since the pivot 230 rotates about the pivot axis R, the translation of the pivot 230 occurs in a second direction different from the first direction. This second direction, or the direction of translation of the pivot 230, is arranged at an angle relative to the direction of movement of the engaging member 236 or the direction of the force F applied to the engaging member 236. In an embodiment, the second direction is arranged substantially perpendicular to the first direction. This movement of the pivot 230 in the second direction applies a force to the flexible member 222, causing the latch 214 to disengage from the rack 210 as previously described.

[0095] In one embodiment, for example, a biasing member 240 of a coil spring extends between the engaging member 236 and the pivoting member 230. After the force F is removed from the engaging member 236, the weight and / or biasing force of the biasing member 240 will cause the pivoting member 230 to translate relative to the seat housing and rotate relative to the engaging member 236. This translation and rotation of the pivoting member 230 causes the engaging member 236 to translate outward to the engaging position.

[0096] exist Figure 18 Another example of the actuator 220 associated with mechanism 203 is illustrated in more detail below. In this embodiment, actuator 220 includes an engagement member 236 pivotally mounted to seat housing 24. Engagement member 236 can rotate inward into the interior of seat housing 24 as it rotates about its axis A from an engaged position to a released position. However, embodiments in which the actuator can rotate relative to seat housing 24 in another orientation are also covered herein.

[0097] For example, a cable, linkage, or other flexible component 222 is coupled to the engaging member 236. In the illustrated non-limiting embodiment, the flexible component 222 is directly coupled to the engaging member 236. Force is transmitted to the flexible component 222 as the engaging member 236 rotates about its axis A from an engaged position to a released position in response to a force F applied thereto. The flexible component 222 may also be connected to the support member 202 to move the support member relative to the housing 200 to adjust the tilt angle of the child safety seat 20. A biasing member 223 is operatively coupled to the actuator 220 such that the biasing force of the biasing member 223 biases the actuator 220 to a first unactuated position. In the illustrated non-limiting embodiment, the biasing member 223 is a helical spring positioned between the surface of the seat housing 24 and the actuator 220; however, embodiments in which the biasing member 223 is arranged in another location or has another configuration (e.g., a torsion spring aligned with axis A) are also covered herein.

[0098] Regardless of the construction of actuator 220, actuator lock 250 is operably connected to actuator 220. Actuator lock 250 can be configured to lock actuator 220 in a releasable position. For example, when a user moves actuator 220 from an engaged position to a released position by operating actuator 220, the user can lock actuator 220 in the released position, allowing support member 202 to move relative to housing 200 even after the user removes force from actuator 220. If the actuator is locked in the released position when child safety seat 20 is installed on vehicle seat 10, the reclining of child safety seat 20 can be configured to automatically adapt to the reclining of vehicle seat as the vehicle seat back angle is adjusted. Once support member 202 is positioned on vehicle seat 10 with child safety seat 20 at the desired angle, actuator lock 250 can be unlocked to move actuator 220 to the engaged position, thereby locking support member 202 in place. Although the actuator lock 250 is described herein as operable to lock the actuator 220 in the release position, it should be understood that the actuator lock 250 may additionally or alternatively be operable to lock the actuator 220 in the engagement position in order to prevent its intentional release.

[0099] After the child safety seat 20 has been positioned and attached to the vehicle seat 10 by the vehicle restraints or latching system, the mechanism 203 for adjusting the tilt angle of the child safety seat 20, as described herein, allows the user to adjust the tilt angle of the child safety seat 20. When adjusting the angle of the vehicle seat 10, the child safety seat 20 does not need to be removed and reattached to the vehicle seat 10. In effect, the mechanism 203 allows the child safety seat 20 to tilt and recline without disengaging the vehicle restraints or latching system.

[0100] For reference Figure 19 In one embodiment, the seat housing 24 of the child seat 20 includes a seat belt 300 separate from the vehicle harness for securing the child within the child seat 20. In the illustrated non-limiting embodiment, the seat belt 300 includes two straps 302, 304 with clips (not shown), each clip being connectable to a buckle 306 (see [link to embodiment]). Figure 22 For example, a hip strap (not shown) may be installed to form shoulder and leg straps around a child positioned within the child seat 20. The shoulder portions of straps 302, 304 may additionally include corresponding portions with clips or buckles (not shown) that can cross the passenger's chest and connect to each other.

[0101] When the child seat 20 is converted into a high-back booster, the seat belt of the child seat 20 is removed or stored outside the upright support cavity 43 and / or area 64, with at least a portion of the child's lower body accommodated within said area 64. Therefore, in embodiments, the seat housing 24 may include one or more storage compartments or pockets for stacking all or part of the seat belt outside the cavity 43 and area 64. For example, at least one of the side components 36, 40 of the seat housing 24 (e.g., in the portion below the armrest 70) may include, for example, a pocket or compartment 310. Figure 20A and 20B In the illustrated non-limiting embodiment, compartment 310 is formed in each of the side members 36, 40. Alternatively or additionally, the support surface 30 of the seat back 28 includes at least one compartment (see...). Figure 20B Compartment 313 may be arranged in the support surface 50 of the seat base 26. However, it should be understood that compartments arranged in any suitable location around the child seat 20 to house or retract part of the seat belt 300 or latching system are within the scope of this disclosure. Compartments 310, 312 may be openable or may have movable doors for selective access to the interior of the compartment.

[0102] To retract the seatbelt 300, the user will loosen the seatbelt 300 and place the corresponding straps 302, 304 and buckles and / or chest clips into the corresponding compartments 310 (e.g., formed in the side members 36, 40). Similarly, the lap straps and buckles 306 of the seatbelt 300 can retract into compartments 313 formed in the support surface 50. When the child seat 20 is configured as a booster, latches (not shown) for securing the child seat 20 to the vehicle seat 10 can be stored in compartments 312 arranged in the seat back 28 (e.g., support surface 30).

[0103] exist Figure 20B and 21In the illustrated non-limiting embodiment, compartment 312 includes a door 314 movable to access its interior 316. In this embodiment, compartment 312 is operable as a harness lock for securing the child seat 20 to the vehicle seat 10 using a vehicle harness. The vehicle harness is fed behind the door 314 and then the door 314 is closed to lock the vehicle harness to the child seat 20.

[0104] According to one aspect of this disclosure, Figure 23A and 23B The illustration depicts a child safety seat 20', which has textiles positioned at least partially on it. Figure 23A and 23B The replacement aspect of the 20' child safety seat disclosed in the document is similar to that described above. Figures 1 to 22 The child safety seat 20 described herein functions similarly to those described above. The child safety seat 20' includes an armrest 70' positioned within the interior of the child safety seat 20'. The armrest 70' is positioned above a support portion 71'. In one aspect, the support portion 71' is integrally formed with the seat shell of the child safety seat 20'. Alternatively or additionally, the support portion 71' may be positioned directly below the armrest 70'. The support portion 71' is configured to receive and / or support padding or textiles 73' thereon. The padding or textiles 73' may help support, for example, the buttocks of a child positioned in the child safety seat 20'.

[0105] For reference Figure 23A , 23B Child safety seats 20 or 20', such as seats 24 and 25, may be further designed to provide improved side impact protection for the occupants of seats 20 or 20'. Side impact protection, as used herein, is intended to describe protection for occupants involved in a collision or impact at the side of a vehicle (e.g., at or near a vehicle door). Child safety seats 20 or 20' as shown may include at least one side impact protector, and in some embodiments, include multiple side impact protectors (shown as 400a, 400b) arranged around seats 20 or 20'. In an exemplary embodiment, one or more side impact protectors 400a, 400b are one or more protruding structures that extend a greater distance into the upright support cavity 43 than the portion of seat 20 or 20' adjacent to the side impact protectors 400a, 400b.

[0106] Figures 23A to 25 An exemplary embodiment of the side impact protector is shown as a shoulder impact protector 400a, which is arranged in or near the area of ​​the seats 20, 20' positioned adjacent to the passenger's shoulder. Figures 23A to 25As shown, the shoulder impact protector 400a is disposed in the upper region 402 of at least one or both of the first upright side member 36 or 36' and the second upright side member 40 or 40' of the seat housing 24. As shown, this upper region 402 includes at least a portion of the first end portion 76 or 76'. In some embodiments, the upper region 402 may alternatively or additionally include a portion of the central region 80 or 80', for example, adjacent to the first end portions 76, 76'. However, it should be understood that any suitable portion of the upright portion 28 may be designed as part of the shoulder impact protector.

[0107] Shoulder impact protector 400a can be made from seat housing 24 (see Figure 24 The inwardly extending outline and / or the inwardly extending, for example, textile 73' ( Figure 23A and 23B It is formed from padding or textiles. In some embodiments, the shoulder impact protector 400a may additionally or alternatively be formed from a portion of the central area 80. For example Figure 25 In the embodiment shown, the central region 80 includes a flange 81 disposed at the upper end 84 of the central region portion 80 and extending inward toward the upright support cavity 43.

[0108] A shoulder impact protector 400a extends or protrudes into an upright support cavity 43 to limit or reduce chest displacement of a passenger during a side impact event. Through this extension into the upright support cavity 43, the inward surface of the shoulder impact protector 400a at the upper region 402 is laterally offset from the inward surface of the adjacent portions of the first upright side member 36 and the second upright side member 40. For example, as... Figure 24 As shown, the inward surface 72a of the seat housing 24 at the first end portion 76 of the upright side members 36, 40 can form a shoulder impact protector 400a. This is in contrast to the inward surface 82 of the adjacent area of ​​the upright side members 36, 40 (e.g., ...). Figure 24 The inward surface of the central portion 80 of the seat housing 24 (and its inner surface 72) extends further toward the interior of the upright support cavity 43. Similarly, as Figure 23A and 23B As shown, the inward surface 75'a defined by the textile 73' at the upper region 402 of the upright side members 36', 40' can also form a shoulder impact protector 400a. Compared to the inward surface 75'b of the textile 73' in the adjacent region of the upright side members 36', 40, this surface 75'a extends further inward toward the center of the upright support cavity 43. Figure 25In a non-limiting embodiment, the flange 81 disposed at the upper end 84 of the central portion 80 also extends further into the interior of the upright support cavity 43, in a similar manner, compared to the inward surface 82 of the adjacent section of the central portion 80. It should be understood, for example... Figure 23A and 23B The protrusion of the shoulder impact protector 400a toward the interior of the upright support cavity 43 shown may be the outline of the seat housing 24, the construction of the textile 73, and additional components (e.g., beneath the material of surface 75a). Figure 25 The result of positioning one or more of the flanges 81).

[0109] Alternatively, or in addition to the shoulder impact protector 400a described above, Figures 23A to 25 The side impact protector is shown as a hip impact protector 400b, disposed in or near the area of ​​the seat 20, 20' positioned adjacent to the passenger's hips. In an embodiment, the hip impact protector 400b is disposed in a lower region 404 of at least one or both of the first upright side member 36 or 36' and the second upright side member 40 or 40'. As shown, this lower region 404 includes at least a portion of the second end portion 78 or 78'. In some embodiments, the lower region 404 may alternatively or additionally include a portion of the central region 80 or 80', for example, adjacent to the second end portion 78, 78'. However, it should be understood that any suitable portion of the upright portion 28 may be designed as part of the hip impact protector 400b.

[0110] The hip impact protector 400b can be made from the seat housing 24 (see Figure 24 The outline of ) and / or made of, for example, textiles 73' ( Figure 23A and 23B The padding or textiles are formed. In some embodiments, the hip impact protector 400b may additionally or alternatively be formed from a portion of the central regions 80, 80'. For example, the end of the central region 80 near the second end portion 78 may include a shelf 83 projecting inward toward the center of the upright support cavity 43.

[0111] The hip impact protector 400b may extend or protrude into the upright support cavity 43 to limit or reduce chest displacement of the passenger during a side impact event. Through this extension into the upright support cavity 43, the inward surface of the hip impact protector 400b is laterally offset from the inward surface of the adjacent portions of the first upright side member 36 and / or the second upright side member 40. For example, as... Figure 24As shown, the inward surface 72b at the second end portion 78 of the upright side members 36, 40 can form a hip impact protector 400b. This surface 72b can be laterally offset from the inward surface of the adjacent area of ​​the upright side members 36, 40. In the illustrated non-limiting embodiment, the inward surface 72b at the second end portion 78 extends further toward the upright support cavity 43 than the inward surface 82 of the adjacent area of ​​the upright side members 36, 40. Similarly, refer to... Figure 23A and 23B The inward surface 75'c of the textile 73' in the lower region of the upright side members 36', 40' can also form a hip impact protector 400b. Compared to the inward surface 75'b of the textile 73' located in adjacent portions of the upright side members 36', 40 (e.g., between the upper region 402 and the lower region 404), this surface 75'c can extend further laterally inward into the upright support cavity 43. Figure 25 In a non-limiting embodiment, compared to the inward surface 82 of the adjacent area of ​​the central portion 80, the shelf 83 arranged at the end of the central portion 80 positioned adjacent to the lower region 404 similarly extends further into the interior of the upright support cavity 43. It should be understood, for example... Figure 23A and 23B The protrusion of the hip impact protector 400b toward the interior of the upright support cavity 43 shown may be the outline of the seat housing 24, the construction of the textile 73, and additional components (e.g., beneath the material of surface 75'c). Figure 25 The result of positioning one or more of the flanges 83).

[0112] In addition to limiting chest displacement, at least one side impact protector (e.g., 400a and / or 400b) included near or aligned with the shoulder and / or hip area of ​​a child seated therein, may also reduce the standard of head injury or specific head movement of a passenger during a side impact event. It should be understood that although side impact protectors 400a and 400b are described as being located in the shoulder and hip area of ​​seats 20 and 20', embodiments including side impact protectors located in another area of ​​seats 20 and 20' are also within the scope of this disclosure. Furthermore, any combination of side impact protectors is covered herein. It should be understood that the first upright side member 36 may have a side impact protector similar to that of the second upright side member 40, or alternatively, may have a different side impact protector than the second upright side member 40. For example, the first upright side members 36 and 36' may not include an impact protector, or may include one or both of a shoulder impact protector 400a and a hip impact protector 400b. Similarly, regardless of the configuration of the impact protector at the first upright side member 36, 36', the second upright side member 40, 40' may not have an impact protector or may have one or both of a shoulder impact protector 400a and a hip impact protector 400b.

[0113] For reference Figures 26 to 31B The illustration depicts another example of a child safety seat 520. As shown, the child safety seat 520 includes a seat base 522 and a rigid seat housing 524 coupled to the seat base 522 for accommodating a child. The child safety seat 520 may be substantially similar in configuration to the child safety seats 20 or 20' previously described herein. Figure 26 In the image shown, the rear panel of the upright portion 528 of the seat housing 524 that forms the rear surface of the child safety seat 520 has been removed.

[0114] The headrest 530 of the child safety seat 520 is movable relative to the seat shell 524 between a retracted position and an extended position, thereby allowing adjustment based on the size of the child positioned within the child safety seat 520. A headrest adjustment mechanism 540 is operable to selectively lock the headrest 530 in a position relative to the seat shell 524. (Reference) Figure 27A , 27B29A and 29B, the headrest adjustment mechanism 540 may include: a mounting bracket 542 fixedly coupled to a portion of the headrest 530; and at least one locking pin 544a, 544b movably coupled to the mounting bracket 542. In the illustrated non-limiting embodiment, the first locking pin 544a is positioned adjacent to a first end 546 of the mounting bracket 542, and the second locking pin 544b is positioned adjacent to a second opposing end 548 of the mounting bracket 542. The mounting bracket 542 may have a longitudinal axis L extending parallel to the seat back (e.g., between the left and right sides of the child safety seat 520), and in embodiments, at least one locking pin 544a, 544b is movable relative to the mounting bracket 542 along the longitudinal axis L.

[0115] In the illustrated non-limiting embodiment, the mounting bracket 542 has a slot 543 formed therein extending parallel to the longitudinal axis L (see [reference]). Figure 29B The rigid pin support member 550 (e.g., a metal tube) is fixedly mounted within a slot in the mounting bracket 542. A first locking pin 544a and a second locking pin 544b may be movably connected to the pin support member 550. For example, the first locking pin 544a may be disposed within a first cavity 552 formed in the pin support member 550, and the second locking pin 544b may be disposed within a second cavity 554 formed in the pin support member 550. In embodiments, the locking pins 544a and 544b are positioned such that their distal ends 545a and 545b are close to the ends 556 and 558 of the pin support member 550. As shown, the length of the pin support member 550, measured along the longitudinal axis L, is greater than the length of the mounting bracket 542. However, embodiments in which the length of the pin support member 550 is substantially equal to the length of the mounting bracket 542 are also within the scope of this disclosure. In one embodiment, cover plate 547 may be positioned to protect pin support member 550 and movable locking pins 544a, 544b from dust and debris.

[0116] At least one locking pin 544a, 544b may be in the first locked or extended position ( Figure 31A (where the headrest 530 cannot move relative to the seat shell 524) and the second unlocked or retracted position ( Figure 31B(Wheelrest 530 is freely translatable relative to seat housing 524) When each of the locking pins 544a, 544b is in the locked position and therefore the headrest adjustment mechanism 540 is in the locked configuration, the distal ends 545a, 545b of each locking pin 544a, 544b are housed within the corresponding locking section disposed on the child safety seat 520. When the locking pins 544a, 544b are in the second unlocked position and therefore the headrest adjustment mechanism 540 is in the unlocked configuration, the second ends 545a, 545b of each locking pin 544a separate from the locking section, allowing the headrest 530 to move relative to seat housing 524. At least one biasing mechanism 560a, 560b is operably coupled to at least one locking pin. In the illustrated non-limiting embodiment, the first biasing mechanism 560a is associated with the first locking pin 544a, and the second biasing mechanism 560b is associated with the second locking pin 544b (see [link]). Figure 29A Each biasing mechanism 560a, 560b has a biasing force operable to bias the corresponding locking pin 544a, 544b toward the locking position. However, this document also covers embodiments in which a single biasing mechanism is operably coupled to both the first locking pin 544a and the second locking pin 544b.

[0117] refer to Figure 27A , 28A In the illustrated non-limiting embodiments, 28B, 29A, and 29B, multiple locking sections are partially formed by at least one frame member, such as two rigid frame members 562a, 562b embedded within a seat frame 524. Frame members 562a, 562b may be substantially identical and may be oriented parallel to each other. In embodiments, frame members 562a, 562b extend generally vertically within an upright portion 528 of the seat housing 524. In some embodiments, frame members 562a, 562b are formed of a material with a stiffness greater than that of the material of the seat housing 524. For example, the seat housing 524 may be formed of a plastic material, and frame members 562a, 562b may be formed of a metallic material (e.g., steel). One or more locking openings 564a, 564b are formed in the frame members 562a, 562b to define discrete predetermined vertical positions of the headrest 530 relative to the seat housing 524. The ends 545a and 545b of the locking pins 544a and 544b can be housed in each of the multiple locking openings 564a and 564b of the corresponding frame components 562a and 562b.

[0118] As shown, each frame component 562a, 562b may be formed from a rectangular tube having an inner portion or first sidewall 566a, 566b positioned closest to the headrest adjustment mechanism 540 and an outer portion or second sidewall 568a, 568b positioned furthest from the headrest adjustment mechanism 540. Because each frame component 562a, 562b is embedded within the seat housing 524, the first walls 570a, 570b of the seat housing 524 may be arranged between the first sidewalls 566a, 566b and the headrest adjustment mechanism 540, and the second walls 572a, 572b of the seat housing 524 may be arranged adjacent to the second sidewalls 568a, 568b. The first 570a, 570b and the second walls 572a, 572b of the seat housing 524 are located on the outer surfaces of the first sidewalls 566a, 566b and the second sidewalls 568a, 568b.

[0119] exist Figure 27A , 28A In the embodiment shown in 29A, a plurality of locking openings 564a, 564b are formed in the second sidewalls 568a, 568b, furthest from the headrest adjustment mechanism 540. Because the ends 545a, 545b of the locking pins 544a, 544b extend through and beyond these locking openings 564a, 564b when engaging with them, at least one cavity 580a, 580b (see [reference]) Figure 31A and 31B A locking pin 544a 544b may be formed in the second wall 572a 572b of the seat housing 524 located on the exterior of the second sidewalls 568a 568b. Each of one or more cavities 580a 580b formed in the second wall 572a 572b may be aligned with at least one of the locking openings 564a 564b of the second sidewall 568a 568b, such that a portion therein may be received. In an embodiment, instead of a plurality of discrete cutouts or cavities 580a 580b having multiple locking openings 564a 564b aligned with the plurality of locking openings 564a 564b, a single cavity may be formed as a slot 580a 580b in the second wall 572a 572b of the seat housing 524. This single slot 580a 580b may be configured such that each of the plurality of locking openings 564a 564b is aligned with the slot 580a 580b. Therefore, instead of the corresponding cutouts in the case of engagement with any of the multiple locking openings 564a, 564b, the ends 545a, 545b of the locking pins 544a, 544b can be accommodated in the slots 580a, 580b formed in the seat housing 524.

[0120] In embodiments where the ends 556, 558 of the pin support member 550 are laterally offset from the ends 546, 548 of the mounting bracket 542, the pin support member 550 may extend through the first walls 570a, 570b of the seat housing 524 and the first side walls 566a, 566b of the frame members 562a, 562b, into the interior of the frame members 562a, 562b. Therefore, at least one opening 582a, 582b for receiving the ends 556, 558 of the pin support member 550 may be formed in the corresponding side walls 566a, 566b of the frame members 562a, 562b, and at least one housing opening 584a, 584b may be formed in the corresponding first walls 570a, 570b of the seat housing 524. Each opening 582a, 582b formed in the first sidewalls 566a, 566b may be aligned with a corresponding housing opening 584a, 584b formed in the first walls 570a, 570b. In the illustrated non-limiting embodiment, a single opening or slot 582a, 582b, 584a, 584b may be formed in each of the first sidewalls 566a, 566b and the first walls 570a, 570b, respectively. Furthermore, these corresponding slots may be aligned with each of a plurality of locking openings 564a, 564b formed in the second sidewalls 568a, 568b.

[0121] The pin support member 550 can therefore be housed within corresponding slots 584a, 584b formed in the first walls 570a, 570b and corresponding slots 582a, 582b formed in the first side walls 566a, 566b. The pin support member 550 remains engaged with these aligned slots 582a, 584a, 582b, 584b, regardless of whether the locking pins 544a, 544b are in the extended or retracted position. When the locking pins 544a, 544b disengage from the cavities 580a, 580b and the plurality of locking openings 564a, 564b, the headrest adjustment mechanism 540 can move relative to the seat housing. The engagement between the body of the pin support member 550 and the slots 582a, 582b, 584a, 584b defines the path of movement of the headrest 530 relative to the seat housing 524.

[0122] Although frame components 562a and 562b are illustrated and described herein as conduits having parallel first sidewalls 566a and 566b and second sidewalls 568a and 568b, in other embodiments, at least one of the frame components 562a and 562b may be a U-shaped or C-shaped channel. In these embodiments, the open ends of the channels 562a and 562b may be arranged adjacent to the ends 556 and 558 of the first walls 570a and 570b and the pin support member 550, such that the pin support member 550 extends through the open ends into the interior of the channels 562a and 562b.

[0123] In other embodiments, for example, where the ends 556, 558 of the pin support member 550 do not extend beyond the mounting bracket 542, the ends 545a, 545b of the locking pins 544a, 544b may be configured to extend through the first walls 570a, 570b, the first side walls 566a, 566b, the second side walls 568a, 568b, and the second walls 572a, 572b. In these embodiments, a single slot or multiple openings 582a, 582b, 584a, 584b may be formed at each of the first side walls 566a, 566b and the first walls 570a, 570b. Furthermore, embodiments in which one of the first side walls 566a, 566b and the first walls 570a, 570b has multiple openings and another of the first side walls 566a, 566b and the first walls 570a, 570b has a single slot are also within the scope of this disclosure. Although the engagement between the headrest adjustment mechanism 540 and the seat housing 524 and channels 562a, 562b is illustrated and described herein as locking pins 544a, 544b and / or pin support members 550 being received within corresponding slots or openings 582a, 582b, 584a, 584b, 564a, 564b, 580a, 580b, other types of engagement between the headrest adjustment mechanism 540 and the seat housing 524 and / or channels 562a, 562b are also covered herein. For example, locking pins 544a, 544b may include at least one snap-fit, for example, protruding radially from the body of locking pins 544a, 544b and being received within the corresponding opening. Alternatively or additionally, frictional means may be used to engage corresponding surfaces of the seat housing 524 or channels 562a, 562b.

[0124] like Figure 29A and 31AAs shown, in each of the embodiments described herein, when the headrest adjustment mechanism 540 is in a locked configuration, locking pins 544a, 544b movably approaching the ends 556, 558 of the pin support member 550 can extend into corresponding openings 580a, 580b formed in the second walls 572a, 572b of the seat housing 524, this extension passing through locking openings 564a, 564b formed in the respective second sidewalls 568a, 568b. Depending on the configuration of the pin support member 550, the pin support member 550 can engage the first walls 570a, 570b of the seat housing 524, and in some embodiments, engage the first sidewalls 566a, 566b of the frame members 562a, 562b. Alternatively, locking pins 544a, 544b may further engage the first sidewalls 566a, 566b of the frame components 562a, 562b, and in some embodiments, engage the corresponding first walls 570a, 570b of the seat housing 524. Thus, each side of the headrest adjustment mechanism 540 engages at least three walls associated with the child safety seat 520 when in the locked configuration, and in some embodiments, engages four separate walls.

[0125] At least one actuator 590 is operatively coupled to locking pins 544a, 544b of the headrest adjustment mechanism 540. In the illustrated non-limiting embodiment, a single actuator 590 is operatively coupled to both the first locking pin 544a and the second locking pin 544b. However, embodiments with a separate actuator associated with each corresponding locking pin 544a, 544b are also covered herein. In an exemplary embodiment, the actuator 590 is operable to change one or both of the locking pins 544a, 544b from a locked position to an unlocked position. As shown, the actuator 590 may include a handle 592 disposed on the outer surface of the child safety seat 520 and movable with the headrest 530. In the illustrated non-limiting embodiment, the handle 592 is disposed on the top of the headrest 530. The handle 592 may be directly or indirectly coupled to one or both of the locking pins 544a, 544b. As shown, the handle 592 can be operably connected to locking pins 544a, 544b via a wire, cable, or other suitable tension member. In the illustrated non-limiting embodiment, a first tension member 594a operably connects a first locking pin 544a to the handle 592, and a second tension member 594b operably connects a second locking pin 544b to the handle 592.

[0126] To operate the actuator 590 and unlock the headrest adjustment mechanism 540, the user applies force to the handle 592. In one embodiment, an upward force is applied to the handle 592. However, embodiments in which the handle 592 moves in another manner (e.g., rotating or pushing inward) are also within the scope of this disclosure. This movement of the handle 592 transmits force via tension members 594a, 594b to the first locking pin 544a and the second locking pin 544b. The force counteracts the biasing forces acting on the biasing members 560a, 560b of the locking pins 544a, 544b, causing the locking pins 544a, 544b to translate inward into the pin support member 550, disengaging from the second walls 572a, 572b and the second side walls 568a, 568b, and entering the unlocked position. When the locking pins 544a and 544b are in the unlocked position, the headrest 530, including the headrest adjustment mechanism 540, is movable relative to the seat housing 524. The user can then translate the headrest 530 to a desired position in which the locking pins 544a and 544b are aligned with the locking openings 564a and 564b. After the release handle 592 is applied, the biasing force of the biasing mechanisms 560a and 560b will bias the locking pins 544a and 544b outward to engage with the frame members 562a and 562b and the seat housing 524.

[0127] In the illustrated non-limiting embodiments, when the locking pins 544a and 544b are in the unlocked position, the ends 545a and 545b of the locking pins 544a and 544b do not protrude or protrude at least beyond the corresponding ends of the pin support members 550. Therefore, the ends 545a and 545b of the locking pins 544a and 544b can be positioned within the frame members 562a and 562b when in the unlocked position. In these embodiments, when the locking pins 544a and 544b are in both the locked and unlocked positions, the pin support member 550 engages with the first sidewalls 566a and 566b and the first walls 570a and 570. However, in other embodiments, such as where the pin support member 550 and the mounting bracket 542 are of the same length, the ends 545a, 545b of the locking pins 544a, 544b can be completely removed from the frame members 562a, 562b when in the unlocked position.
