[0049] The detailed description of one or more embodiments of the apparatus and method disclosed herein with reference to the accompanying drawings is illustrative and not restrictive.

[0050] Figure 1 A schematic diagram of a vehicle seat 2000 and a child restraint system 1000 in a forward position according to an embodiment of the present invention is shown, wherein the child restraint system 1000 is provided with an impact guard 2 in a first position. Figure 2 A perspective view of a ballistic shield 2 which may include an embodiment of the present invention is schematically shown.

[0051] like Figure 1 As shown, the child restraint system 1000 is removably fixed to or supported on a vehicle seat 2000, for example, by a latch or anchor mechanism 31. The latch or anchor system may be referred to as a "lower anchor and tether for children" (e.g., a LATCH system). Alternatively or in addition, the child restraint system 1000 may be removably fixed to the vehicle seat 2000 by a vehicle belt associated with the vehicle seat 2000. The child restraint system 1000 includes a seat body 1 and a base 3. The base 3 is used to be placed on the vehicle seat 2000 and provide a stable support for the seat body 1 thereon. In an exemplary and non-limiting embodiment, the base 3 includes a base portion 30, a support leg 32 connected to the front end of the base portion 30, and a top rest portion 33 extending upward from the rear end of the base portion 30 (see Figure 6 The base portion 30 is configured to be placed on the vehicle seat base 51 of the vehicle seat 2000. The support leg 32 having a fixed or adjustable length is used to abut against the vehicle floor and provide support for the child restraint system 1000 to prevent the child restraint system 1000 from tipping forward during a vehicle collision. The top portion 33 is used to abut against the backrest 52 of the vehicle seat 2000, for example, when used in a rearward position (e.g., Figure 6) to prevent the child restraint system 1000 from tipping over backwards when the vehicle collides. In some embodiments, ISOFIX connectors 31 may be provided on the left and right sides of the rear end of the base portion 30, and the ISOFIX connectors 31 are connected to the plug interface 53 of the vehicle seat 2000 to fix the base 3 to the vehicle seat 2000. In some embodiments, the child restraint system 1000 may also be configured with a top tether (not shown in the figure), one end of the top tether is connected to the seat body 1 or the base 3, and the other end is connected to the anchor point behind the vehicle seat 2000.

[0052] Continue to see Figure 1 The seat body 1 includes a seat portion 11, a backrest portion 12, and side wings 13 on both sides of the seat body 1. The seat portion 11 is used to support a child 3000 (see Figure 5 )'s buttocks. The backrest portion 12 is used to support the back of the child 3000. A headrest 15 with adjustable height is provided on the backrest portion 12, and the headrest 15 is used to support the head of the child 3000. The side wings 13 on both sides of the seat body 1 are used to limit the left and right range of movement of the child 3000. In some embodiments, each side wing 13 includes a first portion 131 provided on one side of the seat portion 11 and a second portion 132 provided on one side of the backrest portion 12. The first portion 131 of the side wing 13 located on both sides of the seat portion 11 can also be called an armrest. According to the left and right direction of the seat body 1, the side wings 13 on both sides can be divided into a left side wing 13A and a right side wing 13B.

[0053] In some embodiments, the seat body 1 is detachably or rotatably mounted on the base 3 . Figure 1 The seat body 1 is shown mounted on the base portion 30 of the base 3 in a first orientation (eg, forward). Figure 6 The seat body 1 is shown rotated to a second orientation (eg, backward). In some alternative embodiments, the seat body 1 and the base 3 may also be connected in a non-rotatable or non-detachable manner.

[0054] It should be noted that the directional terms such as "front", "rear", "left", and "right" of the seat body 1 in the embodiment of the present invention are based on the "front", "rear", "left", and "right" directions of the child sitting in the seat body 1, and the directional terms such as "front", "rear", "left", and "right" of the base 3 refer to the "front", "rear", "left", and "right" directions of the vehicle when the base 3 is installed on the vehicle seat 2000. These directional terms are only used to make the description of the embodiment of the present invention clearer, and are not used to improperly limit the scope of protection of the present invention. Figure 1 As shown, when the seat body 1 is in the forward position, the front-back, left-right directions of the seat body 1 are consistent with the front-back, left-right directions of the base 3. Figure 1The arrows F and B schematically indicate the "front" and "rear" directions of the base 3, and the arrows L and R schematically indicate the "left" and "right" directions of the base 3. It can be understood that when the seat body 1 is in the rearward position (see FIG. Figure 6 ), the front, rear, left, and right directions of the seat body 1 are opposite to the front, rear, left, and right directions of the base 3 respectively.

[0055] The side wing 13 is provided with at least two first positioning components 14. Figure 1 In the illustrated embodiment, the left wing 13A and the right wing 13B are respectively provided with three first positioning components 14. The three first positioning components 14 are arranged at the first position, the second position and the third position of the corresponding left wing 13A or the right wing 13B. Alternatively, in other embodiments, the number of the first positioning components 14 on each side of the left wing 13A and the right wing 13B is not limited to three, and can be set to two or more as needed. According to an embodiment of the present invention, the first positioning components 14 arranged on the left wing 13A are arranged at intervals along the extension direction of the left wing 13A, and the first positioning components 14 arranged on the right wing 13B are arranged at intervals along the extension direction of the right wing 13B. According to an embodiment of the present invention, the first positioning components 14 arranged on the left wing 13A are arranged at different heights of the seat body 1, and the first positioning components 14 arranged on the right wing 13B are arranged at different heights of the seat body 1.

[0056] According to an embodiment of the present invention, the first positioning member 14 at the first position of the left side wing 13A and the right side wing 13B is arranged at the upper edge of the first portion 131 of the left side wing 13A and the right side wing 13B. The first positioning member 14 at the second position and the first positioning member 14 at the third position are arranged at the front edge of the second portion 132 of the left side wing 13A and the right side wing 13B.

[0057] Figure 2 and Figure 3 An example of an impact guard 2 according to an embodiment of the present invention is shown. The impact guard 2 includes a guard body 21 and two straps 22. The guard body 21 has impact absorption properties and is used to cushion the forward movement of a child. In some embodiments, the guard body 21 is an integrated structure of impact absorbing material. As a specific example, the guard body 21 can be a lightweight solid block structure made of foaming materials such as expanded polystyrene (EPS) and expanded polypropylene (EPP) without any plastic shell. In some embodiments, the surface of the guard body 21 can be covered by a soft fabric layer.

[0058] The two straps 22 are, for example, webbing straps. In another example, the two straps 22 are elastic straps. Divided in the left and right directions of the seat body 1, the two straps 22 include a left strap 22A and a right strap 22B. The two straps 22 extend outward from both sides of the body protector 21, respectively. More specifically, the left strap 22A extends from the left side of the body protector 21, and the right strap 22B extends from the right side of the body protector 21. The two straps 22 are respectively provided with second positioning components 23, and the second positioning components 23 are used to selectively connect with any first positioning component 14 on the side wing 13 of the corresponding side (the left side wing 13A or the right side wing 13B) to position the impact guard 2 on the seat body 1. This selective connection can be provided by a releasable pin, buckle, clip or slot, etc.

[0059] Therefore, the child restraint system enables a caregiver to position the impact guard 2 at a more appropriate height according to the body size of the child by connecting the left side strap 22A to one of the first position, the second position and the third position of the left side wing 13A, and connecting the right side strap 22B to one of the first position, the second position and the third position of the right side wing 13B.

[0060] According to some embodiments of the present invention, the child restraint system enables a caregiver to position the impact guard 2 at a more appropriate height to restrain different areas of the child. In the illustrated embodiment, when the second positioning member 23 is coupled to the first position of the first positioning member 14, the guard body 21 is located near the pelvic area of ​​the child (e.g., Figure 5 When the second positioning member 23 is coupled to the second position of the first positioning member 14, the body guard 21 is located near the abdomen area of ​​the child (for example, as shown in FIG. Figure 8 When the second positioning member 23 is connected to the first positioning member 14 in the third position, the protective body 21 is located near the chest area of ​​the child (for example, as shown in FIG. Fig. 9 shown).

[0061] See also Figure 1 and Figure 2 In some embodiments, the first end 221 of each strap 22 is, for example, extended into the interior of the body protector 21 through the holes 20 on both sides of the body protector 21 and connected to the body protector 21, and the second end 222 of each strap 22 is located outside the body protector 21. Each second positioning component 23 is disposed on the second end 222 of each strap 22. When a child sits in the seat body 1, the second positioning component 23 of each strap 22 can be selectively connected to one of the at least two first positioning components 14 of the side wing 13 on the corresponding side according to the height of the child. When each strap 22 is tensioned (for example, tensioned by the elasticity of the strap 22 itself), the body protector 21 adapts to the height of the child and is positioned at a certain height as required.

[0062] See also Figure 1 and Figure 2 According to an embodiment of the present invention, an example of a first positioning member 14 and a second positioning member 23 is shown. The first positioning member 14 includes a latch assembly (e.g., a recessed pin on the edge surface of the side wing) selectively engaged by the second positioning member 23 (e.g., the hook shown). The first positioning member 14 includes a recess 140 formed on the side wing 13 and a connecting pin 141 installed in the recess 140. The second positioning member 23 includes a connecting hook, which is used to selectively engage with the connecting pin 141. Of course, the implementation of the first positioning member 14 and the second positioning member 23 is not limited to the above examples. For example, in other embodiments, one of the first positioning member 14 and the second positioning member 23 is a male buckle and the other is a female buckle, and the male buckle and the female buckle can be selectively engaged. In some alternative embodiments, one of the first positioning member 14 and the second positioning member 23 can be a button and the other can be a button strap.

[0063] In some embodiments, each strap 22 may be a webbing without greater elasticity. Alternatively or in addition, each strap 22 has an adjustable length. The impact guard 2 is provided with a strap adjustment mechanism 24, which is used to adjust the length of each strap 22 outside the guard body 21. Specifically, when a child is sitting in the seat body 1, the length of each strap 22 outside the guard body 21 can be lengthened first to facilitate the caregiver to connect each second positioning component 23 with the corresponding first positioning component 14. Then, the length of each strap 22 outside the guard body 21 can be shortened by operating the strap adjustment mechanism 24 to tighten each strap 21 to securely restrain the child between the impact guard 2 and the seat body 1.

[0064] Figure 3 and Figure 4 An exemplary embodiment of the belt adjustment mechanism 24 is shown. The belt adjustment structure 24 may include a retractor 241, which is mounted on the body protector 21 and connected to the first ends 221 of the two belts 22 at the same time. The retractor 241 is used to apply a retracting force to each belt 22. In this way, the two belts 22 can be retracted by the same retractor 241, thereby shortening the length of each belt 22 located outside the body protector 21. When any belt 22 is subjected to external tension, the retractor 241 can be pulled by the belt 22 to release the belt 22, and the other belt 22 can be released from the retractor 241 accordingly, thereby lengthening the length of each belt 22 located outside the body protector 21. Of course, in some embodiments, the number of belts 22 and the number of retractors 241 may correspond one to one, and one retractor 241 is used to control the retraction of one belt 22.

[0065] See also Figure 4In some embodiments, the retractor 241 may include a surface shell 2402 and a bottom shell 2403, and the surface shell 2402 and the bottom shell 2403 are connected to form a receiving chamber 240. The retractor 241 includes a reel 2411 and a reset member 2412 accommodated in the receiving chamber 240. The first ends 221 of the two belts 22 are wound on the reel 2411. The reset member 2412 is connected to the reel 2411, and the reset member 2412 applies a reeling force to each belt 22 through the reel 2411. In some embodiments, the reset member 2412 may be a coil spring.

[0066] Continue to see Figure 4 In some embodiments, the belt adjustment mechanism 24 may further include a locking device 242, and the locking device 242 has a locked state and a released state. In the locked state, when the belt 22 is subjected to external tension, the locking device 242 restricts the retractor 241 from releasing the belt 22. In the released state, the locking device 242 allows the retractor 241 to release the belt 22. It can be understood that in the process of connecting the second positioning component 23 on each belt 22 with the corresponding first positioning component 14, the locking device 242 can be in the released state to allow the length of each belt 22 outside the body protector 21 to be adjusted. When the second positioning component 23 of each belt 22 is connected to the corresponding first positioning component 14 and each belt 22 is tensioned, the locking device 242 is in the locked state. This can prevent the belt 22 from being released unexpectedly when the child makes a forward leaning movement due to an accident in the vehicle, causing the protection failure of the impact body 2.

[0067] Figure 4 An exemplary embodiment of the locking device 242 is shown, but the embodiment of the locking device 242 is not limited to the following example. Figure 4, the locking device 242 may include a ratchet 2421, a pawl 2422, an elastic member 2423 and a release member 2424. The ratchet 2421, the pawl 2422 and the elastic member 2423 may be installed in the accommodating chamber 240. The ratchet 2421 is disposed on the reel 2411, and the two are, for example, integrally formed. The pawl 2422 can rotate around an axis X2-X2 parallel to the axis X1-X1 of the reel 2411. In some embodiments, the pawl 2422 has a pivot 24221, and the bottom shell 2403 may be provided with a structure for positioning the pivot 24221 (for example, a plurality of bosses 24031 extending from the bottom shell 2403 form a space for accommodating the pivot 24221), and the center line of the pivot 24221 forms the axis X2-X2. The elastic member 2423 is used to keep the pawl 2422 engaged with the ratchet 2421. More specifically, the elastic member 2423 applies a biasing force to the pawl 2422, so that the pawl 2422 has a tendency to rotate around the pivot 24221 toward the ratchet 2421. The elastic member 2423 is, for example, a torsion spring, which is respectively connected to the pawl 2422 and the bottom shell 2403. The release member 2424 is used to drive the pawl 2422 to disengage from the ratchet 2421.

[0068] It can be understood that the pawl 2422 is kept meshed with the ratchet teeth of the ratchet wheel 2421 under the action of the elastic member 2423, which corresponds to the locked state of the locking device 242. At this time, the locking device 242 does not interfere with the retractor 241 retracting each belt 22, so that each belt 22 can be automatically tensioned, but the retractor 241 is not allowed to release each belt 22. When it is necessary to release each belt 22, the release member 2424 can drive the pawl 2422 to move around the axis X2-X2 in a direction away from the ratchet wheel 2421, so that the pawl 2422 is disengaged from the ratchet teeth of the ratchet wheel 2421, and the locking device 242 is switched to the unlocked state allowing the retractor 241 to release each belt 22.

[0069] Continue to see Figure 4In some embodiments, the housing 2402 may be provided with a larger hole 24021, and the hole 24021 includes two opposite side walls 24021a and 24021b. The housing 2402 may also be provided with a mask 2401, which covers the hole 24021, and a smaller hole 24011 is provided at a position of the mask 2401 corresponding to the side wall 24021b. The pawl 2422 may be provided with a connecting portion 24222, and when the pawl 2422 is engaged with the ratchet 2421, the connecting portion 24222 is close to the side wall 24021a; when the pawl 2422 is disengaged from the ratchet 2421, the connecting portion 24222 is close to the side wall 24021b. The release member 2424 can be a deformable strip (such as a webbing or a plastic strip), the first end of the release member 2424 is connected to the connecting portion 24222, and the second end of the release member 2424 passes through the holes 24021 and 24011 in sequence.
