Description

Child safety seat Technical Field

[0001] The present application relates to a child safety seat. Background Art

[0002] Child safety seats are usually installed in vehicles such as cars to provide a safe and comfortable riding environment for children. In order to stably install the child safety seat in the car, the child safety seat usually includes a base and a carrier (such as a seat or a sleeping basket) connected to the base, wherein the base is used to be installed in the car and the carrier is for the child to sit on. Moreover, because the seat can be detached from the base, the user can directly remove the carrier and the child from the base when carrying the child. The base of existing child safety seats has many parts, especially the parts of the connection structure between the base and the carrier, which causes unnecessary increase in weight. Therefore, it is desired to provide a new connection structure to reduce the number of parts.

[0003] On the other hand, it is desirable that the base of the child safety seat has an adjustment structure to allow adjustment of the angle between the base and the car seat. Moreover, it is desirable that the adjustment structure of the base has a structure that is convenient for user operation.

[0004] On the other hand, child safety seats typically feature a connecting strap to connect the base to a car seat. In some designs, the connecting strap extends from the upper portion of the child safety seat's base, through the base, to the lower portion, where it connects to the car seat. In such cases, it is desirable to provide a stopper to limit the range of movement of the connecting strap relative to the base. Furthermore, it is desirable for the child safety seat base to provide a storage feature to securely store the connecting strap and its anchor connector when not connected to the car seat.

[0071] While the invention has been illustrated and described herein with reference to particular embodiments, the invention is not limited to the details shown, but rather various modifications may be made within the scope and range of equivalents of the claims and without departing from the invention.

[0072] The descriptions of directions such as "front", "back", "up", and "down" involved in this document are only for the convenience of understanding. The present invention is not limited to these directions, but can be adjusted according to actual conditions.

[0073] 1 and 2 , a base 100 of a child safety seat according to the present application will be generally described.

[0074] The base 100 is composed of an upper cover 101 and a lower cover 102. It should be understood that the upper cover 101 and the lower cover 102 can be an integral component, and thus the upper cover 101 and the lower cover 102 are collectively referred to as the body of the base 100. The components provided to the upper cover 101 or the lower cover 102 described below can be understood as being provided to the body of the base 100.

[0075] The rear end of the base 100 (i.e., the right side in Figures 1 and 2) rests against the backrest of the car seat. A push rod 103 is provided at the rear end of the base 100, specifically at the upper portion of the rear end of the upper cover 101. Push rod 103 rests against the backrest of the car seat, ensuring a stable installation of the base 100 in the vehicle. The upper cover 101 of the base 100 defines a first connecting slot 104 and a second connecting slot 105 extending transversely, aligned longitudinally (i.e., front-to-back).

[0076] The base 100 is provided with at least one first connector 110 and at least one second connector 120. The first connector 110 and the second connector 120 are at least partially disposed in the base 100 and exposed above the upper cover 101 through the first connecting groove 104 and the second connecting groove 105 respectively.

[0077] A release member 130 is provided at the front of the base 100 , and a user can control the first connecting member 110 and the second connecting member 120 through the release member 130 , which will be described in detail below.

[0078] Referring to Figure 3A , the second connecting groove 105 of this embodiment is vertically recessed from the upper surface of the upper cover 101 and is divided into two transversely aligned sections. Specifically, the two sections of the second connecting groove 105 are disposed on the left and right sides of the base 100, respectively. In this embodiment, two second connecting members 120 are disposed in each of the two sections of the second connecting groove 105. In other embodiments, the second connecting groove 105 may be a continuous section extending across the entire transverse dimension of the upper cover 101, and one or more second connecting members 120 may be disposed at any transverse position of the second connecting groove 105.

[0079] 3B , the first connection slot 104 of this embodiment is vertically recessed from the upper surface of the upper cover 101 and extends across most of the lateral dimension of the upper cover 101. In this embodiment, a single first connection member 110 is disposed in the lateral middle of the first connection slot 104. In other embodiments, a single first connection member 110 may be disposed at one lateral side of the first connection slot 104, or multiple first connection members 110 may be distributed along the lateral direction of the first connection slot 104.

[0080] A child safety seat carrier 500 according to the present application will be described with reference to Figures 4 and 5. The carrier 500 includes a seating portion 510 for a child to sit on, and a first crossbar 520 and a second crossbar 530 located on the lower surface of the seating portion 510. The first crossbar 520 and the second crossbar 530 can be inserted into the first connecting groove 104 and the second connecting groove 105 of the base 100, respectively, and locked by the first connector 110 and the second connector 120, respectively (see Figure 2), thereby securely coupling the carrier 500 to the base 100.

[0081] In this embodiment, the carrier 500 is in the form of a sleeping cot. In other embodiments, the carrier 500 may also be in a suitable form such as a seat, as long as it has a first crossbar 520 and a second crossbar 530 so as to be coupled to the base 100.

[0082] The base 100 of the child safety seat according to the present application is further described with reference to Figures 6 to 8. Figures 6 to 8 conceal the upper cover 101 of the base 100, thereby fully illustrating the release member 130, the first connecting member 110, and the second connecting member 120. Furthermore, the slide member 140, at least one linkage member 150, the fixing seat 155, the first shaft 193, the second shaft 194, the release member shaft 195, the first drive rod 196, and the second drive rod 197 provided on the base 100 are also illustrated.

[0083] In general, the first connector 110 and the second connector 120 are respectively operatively engaged with the carrier 500. That is, the first connector 110 and the second connector 120 are respectively switchable between a locked position and an unlocked position to lock or unlock the carrier 500 (specifically, the first cross bar 520 and the second cross bar 530 at the bottom of the carrier 500, see FIG. 5 ).

[0084] The release member 130 is exposed on the outside of the base 100 for user operation. The slider 140 is connected to the release member 130 and can be driven by the release member 130 to drive the first connector 110 to release the carrier 500. The linkage member 150 is connected between the slider 140 and the second connector 120 and can be driven by the slider 140 to drive the second connector 120 to release the carrier 500.

[0085] In this embodiment, the first connecting member 110 and the second connecting member 120 are respectively disposed on the upper cover 101. The release member 130, the sliding member 140, and the linkage member 150 are respectively disposed on the lower cover 102. However, as previously mentioned, the upper cover 101 and the lower cover 102 can be integrally formed, and thus the aforementioned components are actually disposed on the main body formed by the upper cover 101 and the lower cover 102.

[0086] Specifically, the release member 130 is rotatably connected to the front end of the base 100 body (specifically, the front end of the lower cover 102) via a release member shaft 195, allowing rotation relative to the base 100 body about a transverse axis. The release member 130 includes a release portion 131 and a release slot 132. The release portion 131 can be operated from outside the base 100 to rotate the release member 130 relative to the base 100 body. For example, the release portion 131 can be a handle with an arcuate profile to provide a good appearance and operating experience. The release slot 132 is connected to the first end 141 (specifically, the front end) of the slider 140. More specifically, with reference to FIG10A , the release slot 132 is a linear or curved slot extending generally vertically. A release pin 133 is provided at the first end 141 of the slider 140, which is, for example, fixed to the slider 140. The release pin 133 can slide in the release slot 132. Therefore, when the release member 130 rotates relative to the main body of the base 100, the release pin 133 moves longitudinally while sliding along the release slot 132, thereby driving the sliding member 140 to slide longitudinally, so that the rotation of the release member 130 relative to the main body is converted into the sliding of the sliding member 140 along the main body.

[0087] The main body of the slider 140 is a long, generally longitudinally extending T-shaped plate. Its front end 141 (the foot end of the T) is connected to the release member 130, and its rear end 142 (the head end of the T) is connected to the linkage member 150. More specifically, the slider 140 includes a longitudinal portion 144 and a transverse portion 145. One end of the longitudinal portion 144 is connected to the middle of the transverse portion 145. The end of the longitudinal portion 144, distal from the transverse portion 145, is connected to the release member 130, and both ends of the transverse portion 145 are connected to the two linkage members 150, respectively. The longitudinal portion 144 has a vertically extending opening 144a through which the first connector 110 extends, ensuring that the sliding of the slider 140 does not hinder the rotation of the first connector 110.

[0088] The slider 140 is configured to slide longitudinally relative to the body of the base 100 (specifically, the lower cover 102). The slider 140 includes a driving portion 143 connected to the first drive rod 196. In this embodiment, the driving portion 143 is in the form of a groove extending downward and opening forward, so as to engage the first drive rod 196 and drive the first drive rod 196 to move longitudinally. More specifically, the driving portion 143 is disposed between the ends of the longitudinal portion 144 and extends downward. The longitudinal portion 144 is connected to the release member 130 via a release pin 133. The contact point between the driving portion 143 and the first drive rod 196 and the release pin 133 are both located below the longitudinal portion 144 and are at approximately the same vertical height. The contact point between the driving portion 143 and the first drive rod 196 and the release pin 133 are both located approximately at the transverse center of the base 100. Specifically, the contact point between the driving portion 143 and the first driving rod 196 is substantially aligned with the release pin 133 both laterally and vertically, and is spaced apart only longitudinally. This allows the driving force of the release pin 133 to be accurately transmitted longitudinally to the first driving rod 196 via the slider 140 without generating lateral or vertical force components. In other embodiments, the driving portion 143 may take any suitable form, such as a ring or lever, as long as it can drive the first driving rod 196 to move longitudinally.

[0089] The first connector 110 is rotatably connected to the base 100 body, specifically, to the upper cover 101 of the base 100, via a transversely extending first shaft 193. Although the upper cover 101 is not shown in Figures 6-8 , it should be understood that the upper cover 101 includes a connection structure that allows both ends of the first shaft 193 to be inserted therein. Referring to Figures 6-8 and Figure 10A , the upper end of the first connector 110 is a forward-opening first hook 111, and the lower end of the first connector 110 is connected to a first drive rod 196. The first drive rod 196 is arranged parallel to and below the first shaft 193. Therefore, the first hook 111 and the first drive rod 196 are located on opposite sides of the first shaft 193. Rotating the first connector 110 counterclockwise in Figure 10A represents locking, while rotating it clockwise in Figure 10A represents releasing.

[0090] When the slider 140 slides relative to the base 100, the driving portion 143 drives the first connector 110 via the first driving rod 196 to release the carrier 500. Specifically, the slider 140 slides forward under the drive of the release member 130, and the driving portion 143 of the slider 140 drives the first driving rod 196 forward. The forward movement of the first driving rod 196 causes the first connector 110 to rotate clockwise in FIG. 10A , i.e., toward the release direction, rotating the first connector 110 to the released position.

[0091] The first retaining member 191 applies a biasing force to the first connecting member 110 in a direction opposite to the direction in which the sliding member 140 slides under the action of the release member 130. Specifically, the first retaining member 191 is disposed between the body of the base 100 and the first drive rod 196, retaining the first connecting member 110 in a position to engage the carrier 500. The first retaining member 191 can be configured as a tension spring, with its ends connected to the body of the base 100 and the first drive rod 196, respectively, to apply a rearward pulling force to the first drive rod 196, thereby maintaining the first connecting member 110 in the locked position.

[0092] With reference to Figures 6 to 8 and Figure 10B, in this embodiment, the linkage member 150 is shaped like an elongated rod extending generally longitudinally. Both the front end 151 and the rear end 152 of the linkage member 150 are annular. The front end 151 of the linkage member 150 is sleeved onto the second end 142 of the sliding member 140. The second end 142 is shaped like a rod extending transversely, for example, extending transversely to the left and right sides, so that the front ends 151 of the two linkage members 150 can pivotally sleeve onto the transverse sides of the second end 142. The rear end 152 of the linkage member 150 is sleeved onto the second drive rod 197, which is connected to the second connecting member 120. Therefore, when the sliding member 140 slides forward relative to the base 100, the sliding member 140 drives the second drive rod 197 forward via the linkage member 150.

[0093] The second connector 120 is rotatably connected to the main body of the base 100 via a second shaft 194, specifically to a fixing base 155. The fixing base 155 is fixed to the bottom of the upper cover 101 of the base 100. The upper end of the second connector 120 is a rearwardly open second hook 121. The second connector 120 is connected to a second drive rod 197 between the second hook 121 and the second shaft 194. The second drive rod 197 is arranged parallel to and above the second shaft 194. That is, unlike the first connector 110, the second drive rod 197 and the second hook 121 are located on the same side of the second shaft 194. Rotating the second connector 120 clockwise in FIG. 10B indicates locking, while rotating it counterclockwise in FIG. 10B indicates releasing.

[0094] When the sliding member 140 drives the second driving rod 197 to move forward through the linkage member 150, the second driving rod 197 drives the second connecting member 120 to rotate counterclockwise, that is, to rotate toward the unlocking direction, so that the second connecting member 120 rotates to the unlocking position.

[0095] The second retaining member 192 applies a biasing force to the second drive rod 197 in a direction opposite to the direction in which the slider 140 is driven by the release member 130. Specifically, the second retaining member 192 is disposed between the body of the base 100 and the second drive rod 197, maintaining the second connecting member 120 in a locked position toward the carrier 500. The second retaining member 192 can be configured as a tension spring, with its ends respectively connected to the body of the base 100 and the second drive rod 197, to apply a rearward pulling force to the second drive rod 197, thereby maintaining the second connecting member 120 in the locked position.

[0096] In this embodiment, the front ends 151 of the two linkage members 150 are respectively connected to the lateral ends of the sliding member 140, the rear ends 152 of the two linkage members 150 are respectively connected to the corresponding second drive rods 197, and the two second drive rods 197 are respectively connected to the two second connecting members 120, and the rear ends 152 of the two linkage members 150 are located between the two second connecting members 120. In other embodiments, a single linkage member 150 may be provided, whose front end 151 is connected to the sliding member 140 and the rear end 152 is connected to the single second drive rod 197. Furthermore, the single second drive rod 197 can be connected to the two second connecting members 120, for example, extending laterally between the two second connecting members 120.

[0097] According to the present application, when the slider 140 is driven by the release member 130 to slide, the first hook portion 111 of the first connector 110 and the second hook portion 121 of the second connector 120 rotate in opposite directions to release the carrier 500. Accordingly, when the slider 140 is not driven by the release member 130 to slide, the first hook portion 111 and the second hook portion 121 rotate in opposite directions under the bias of the first retaining member 191 and the second retaining member 192 to lock the carrier 500. With reference to Figures 3A and 3B , when the first connector 110 and the second connector 120 are in the locked position, the first hook portion 111 and the second hook portion 121 are exposed above the base 100 through the first connecting slot 104 and the second connecting slot 105, respectively, and cooperate with the first connecting slot 104 and the second connecting slot 105 to form a closed space to lock the first crossbar 520 and the second crossbar 530 (not shown).

[0098] Thanks to the base 100 structure of the present application, the number of parts of the base 100 can be reduced, especially allowing the use of a single first connector 110 , which significantly reduces the number of parts compared to the base 100 structure using multiple first connectors 110 .

[0099] The adjustment structure according to the present application is generally described with reference to FIG. 11 to FIG. 12B . The adjustment structure includes an adjustment member 160 , an operating member 170 , and a locking member 175 .

[0100] In this embodiment, the adjustment member 160 is a foot pad disposed at the rear end 152 of the lower side of the base 100. It can move between a retracted position shown in Figure 12A and an extended position shown in Figure 12B to adjust the pitch angle of the base 100 relative to the car seat (not shown). For example, when the adjustment member 160 is in the retracted position shown in Figure 12A, the lower surface of the adjustment member 160 is substantially flush with the lower surface of the body of the base 100, so that the base 100 is placed horizontally on the car seat, so that the base 100 (and the entire child safety seat) is approximately horizontal. When the adjustment member 160 is in the extended position shown in Figure 12B, the lower surface of the adjustment member 160 is tilted backward and downward relative to the body of the base 100, so that the rear end of the base 100 is raised upward, causing the base 100 (and the entire child safety seat) to tilt forward. The foot pad can be in a plurality of different extended positions to allow the base 100 to be set to different pitch angles, Figure 12B only shows one of the extended positions.

[0101] In other embodiments, the adjustment member 160 may be provided at other appropriate locations of the child safety seat, such as a rear surface, a side surface, etc., to adjust the angle of the child safety seat in different directions.

[0102] The engaging member 175 is disposed at the rear of the base 100 and is capable of retaining the adjusting member 160 in the extended position or the retracted position. The operating member 170 is disposed at the rear of the base 100 and is at least partially exposed behind the base 100 so that a user can operate the engaging member 175 to retain the adjusting member 160 or release the adjusting member 160.

[0103] The adjustment structure is further described with reference to Figures 14A and 14B.

[0104] One end of the adjustment member 160 is rotatably connected to the body of the base 100. Specifically, the front end of the adjustment member 160 is rotatably connected to the body of the base 100, and the connection structure at the front end will be described in detail below. The other end (i.e., the rear end) of the adjustment member 160 has at least one stop portion 164 arranged along the rotation direction of the adjustment member 160, and each stop portion 164 corresponds to an extended position or a retracted position. The stop portion 164 is specifically a hook extending toward the rear and open toward the bottom. A first elastic member 198, such as a compression spring, is arranged between the body of the base 100 (specifically the lower cover 102) and the adjustment member 160 to bias the adjustment member 160 toward the extended position.

[0105] 14A, 14B, and 15, the engaging member 175 can be engaged with either stop 164 to maintain the adjusting member 160 in the extended or retracted position. Specifically, the engaging member 175 is rotatably connected to the base 100 and is generally L-shaped in the side cross-sectional view (i.e., FIG14A). The engaging member 175 is rotatably connected to the base 100 at the corner of the L-shape and includes an arm 176 and an engaging portion 177, respectively located at the two ends of the L-shape. The arm 176 extends approximately rearward from the rotation axis of the engaging member 175 and engages with the operating portion 171 so as to be driven by the operating portion 171. The engaging portion 177 is disposed at the lower end of the engaging member 175 and can be engaged with the stop 164 of the adjusting member 160.

[0106] The second elastic member 199 is disposed between the body of the base 100 and the engaging member 175 to bias the engaging member 175 toward the position of the locking adjusting member 160. For example, one end of the second elastic member 199 abuts against the lower surface of the lower cover 102 of the base 100, and the other end abuts against the upper surface of the arm 176.

[0107] In this embodiment, the adjustment member 160 and the engaging member 175 each rotate about a transverse axis relative to the body of the base 100, and the engaging portion 177 extends transversely to facilitate a compact adjustment structure. In other embodiments, the adjustment member 160 and the engaging member 175 may also be configured in other appropriate forms, such as linearly movable relative to the base 100.

[0108] 14C , the operating member 170 includes an operating portion 171 and a transmission rod 172. The operating portion 171 can be operated from outside the base 100, for example, in the form of a handle. The transmission rod 172 is coupled to the lower surface of the arm 176 of the engaging member 175 to drive the engaging member 175 to rotate against the biasing force of the second elastic member 199. The transmission rod 172 is, for example, a rod extending in the transverse direction so as to stably engage the arm 176.

[0109] In this embodiment, the operating member 170 is configured to move vertically relative to the base 100 to drive the engaging portion 177 of the engaging member 175 to rotate relative to the base 100 in a direction away from the adjusting member 160. When the user does not operate the operating member 170, the engaging member 175 tends to rotate clockwise in FIG. 14A under the action of the second elastic member 199, causing the engaging portion 177 to engage with any stop portion 164 of the adjusting member 160, thereby maintaining the adjusting member 160 in the retracted position or the extended position.

[0110] When the user moves the operating member 170 upward, the transmission rod 172 of the operating member 170 drives the arm 176 of the engaging member 175 to move in a counterclockwise direction in FIG14A against the bias of the second elastic member 199, causing the engaging member 175 to rotate counterclockwise, thereby moving the engaging portion 177 away from the adjusting member 160 and away from the stop 164. At this point, the adjusting member 160 tends to move toward the extended position under the bias of the first elastic member 198. The user can then press down on the base 100 relative to the car seat (or other surface on which the base 100 is located) to move the adjusting member 160 to the retracted position. The user then releases the operating member 170, causing the engaging member 175 to once again maintain the position of the adjusting member 160.

[0111] Thanks to the adjustment structure of the present application, the adjustment member 160 can be held or released by the linearly moving operating member 170 .

[0112] 16 to 18B , the assembly relationship between the adjustment member 160 and the base 100 is further described.

[0113] The adjustment member 160 is connected to the base 100 body via a first pivot portion 162 and a second pivot portion 163 that oppose each other. The first pivot portion 162 is cylindrical, and the second pivot portion 163 includes a pivot shaft 163a, an extension portion 163b, and a protrusion 163c. The pivot shaft 163a extends opposite the first pivot portion 162. The extension portion 163b extends radially outward from the outer circumference of the pivot shaft 163a. ​​The protrusion 163c extends from the end of the extension portion 163b that is away from the pivot shaft 163a and is located on either side of the extension portion 163b, along with the pivot shaft 163a.

[0114] The base 100 has a circular hole 107 on one side connected to the adjustment member 160 and a special-shaped slot 106 on the other side. Special-shaped slot 106 is configured to allow the second pivot portion 163 to slide into the special-shaped slot 106 from the outside of the base 100 when the first pivot portion 162 of the adjustment member 160 is inserted into the circular hole 107, while the pivot axis 163a of the second pivot portion 163 is kept rotatable in the special-shaped slot 106.

[0115] More specifically, the special-shaped groove 106 includes a guide portion 106a and an accommodating portion 106b. The guide portion 106a extends vertically to the exterior of the base 100 and engages with the protrusion 163c of the second pivot portion 163 to prevent the second pivot portion 163 from disengaging the special-shaped groove 106. The accommodating portion 106b extends longitudinally from the guide portion 106a and accommodates the pivot shaft 163a of the second pivot portion 163.

[0116] During the process of assembling the adjusting member 160 to the main body of the base 100, the first pivot portion 162 is first inserted into the circular hole 107, and then the pivot shaft 163a of the second pivot portion 163 is moved into the accommodating portion 106b through the guide portion 106a of the special-shaped groove 106, thereby facilitating the easy assembly of the adjusting member 160.

[0117] A first embodiment of a limiting member 300 according to the present application will be described with reference to FIG. 19 .

[0118] The child safety seat includes a connecting strap 200 for connecting the base 100 to a vehicle seat (not shown). Specifically, at least a portion of the connecting strap 200 is connected to the upper portion of the base 100 (specifically, the upper surface 181 of the base 100). The connecting strap 200 passes through the base 100 from above to below the base 100 (i.e., below in FIG. 19 ) and is connected to the vehicle seat, thereby mounting the base 100 on the vehicle seat.

[0119] In this embodiment, the middle section of the connecting belt 200 is connected to the upper portion of the base 100 , and both ends of the connecting belt 200 pass through the base 100 and reach the bottom of the base 100 .

[0120] The base 100 is provided with a through-hole 182 extending through the base 100, through which the connecting strap 200 can pass from the upper surface 181 of the base 100 through the through-hole 182 to reach the bottom of the base 100. In this embodiment, two through-holes 182 are provided on either side of the base 100 to allow both ends of the connecting strap 200 to pass through the base 100.

[0121] It should be understood that the connecting belt 200 is not fixed to the base 100, but can slide relative to the base 100. In order to limit the sliding range of the connecting belt 200 in the longitudinal direction relative to the base 100, in particular to prevent the connecting belt 200 from excessively sliding in the longitudinal direction relative to the base 100 and thereby obstructing the second connecting member 120 (see FIG. 2 ), the base 100 is provided with a limiting passage for the connecting belt 200 to pass through. The limiting passage movably connects the connecting belt 200 to the base 100, and the limiting passage is located between the two penetration openings 182.

[0122] Specifically, the limiting channel is provided by a limiting member 300 provided on the base 100. The limiting member 300 is a belt or plate that crosses the connecting belt 200. For example, the connecting belt 200 extends in the transverse direction and the limiting member 300 extends in the longitudinal direction, so the limiting member 300 crosses the connecting belt 200. The limiting member 300 has two end portions 301 and a middle section 302 located between the two end portions. The two end portions 301 are connected to the upper surface 181 of the base 100, so that a limiting channel is formed between the middle section 302 and the upper surface 181 of the base 100. The width of the limiting channel is close to the width of the connecting belt 200, thereby preventing the connecting belt 200 from sliding up and down in the longitudinal direction relative to the base 100 in the limiting channel.

[0123] With reference to Figures 19 and 20 , in this embodiment, the upper surface 181 of the base 100 is provided with two upper surface retaining holes 181a, and the two ends 301 of the retaining member 300 are respectively fixed to the two upper surface retaining holes 181a. More specifically, the two ends 301 of the retaining member 300 are respectively passed through the two upper surface retaining holes 181a from above and are tied below the upper surface 181 to be fixed to the upper surface. In other embodiments, the two ends 301 of the retaining member can be fixed to the upper surface 181 of the base 100 by other means, such as by snap fastening, wrapping, or Velcro.

[0124] 21 and 22 , the ends of the connecting strap 200 extend through the insertion openings 182 on either side of the base 100 and extend to the bottom of the base 100. Anchor connectors 210 are provided at each end of the connecting strap 200. The anchor connectors 210 can engage with corresponding fittings (not shown) on a vehicle seat, allowing the base 100 to be mounted to the vehicle seat. A storage structure is provided below the base 100 to store the connecting strap 200 and anchor connectors 210 when the base 100 is not connected to the vehicle seat using the connecting strap 200.

[0125] Specifically, the bottom of the base 100 is provided with a receiving groove 183 capable of accommodating at least one of the connecting strap 200 and the anchoring connector 210. More specifically, the receiving groove 183 is formed by being recessed upward from the bottom surface of the base 100. Two receiving grooves 183 are provided on either side of the base 100 and extend generally in the longitudinal direction. Figure 21 schematically illustrates the connecting strap 200 folded and accommodated in the receiving grooves 183. It should be understood that the connecting strap 200 may be a flexible strap and, therefore, can be rolled, folded, or twisted to accommodate itself in the receiving grooves 183.

[0126] Two anchoring joints 210 are respectively connected to both ends of the connecting belt 200. The anchoring joints 210 are, for example, in the form of snaps and have engaging hooks 211 for connection to a vehicle seat.

[0127] The receiving groove 183 is provided with a receiving engagement rod 184, to which the engagement hook of the anchor joint 210 can be engaged. Specifically, the receiving engagement rod 184 extends generally in the transverse direction and is located at the opening of the receiving groove 183. Therefore, when the connecting strap 200 is stored in the receiving groove 183, the anchor joint 210 can be easily engaged with the receiving engagement rod 183. In this embodiment, two receiving engagement rods 184 are respectively provided in the receiving groove 183 on both sides of the base 100, and these two receiving engagement rods 184 are arranged at different longitudinal positions on the base 100. In other words, the distance between the receiving engagement rod 184 on one side and the insertion opening 182 is greater than the distance between the receiving engagement rod 184 on the other side and the insertion opening 182, or in other words, the receiving engagement rod 184 on one side is positioned closer to the front of the base 100 (i.e., the lower left side in FIG. 21 ) than the receiving engagement rod 184 on the other side. The side with a larger distance between the receiving engagement rod 184 and the insertion opening 182 provides a larger storage space for the connecting belt 200, thereby being able to accommodate a length adjustment device (not shown) of the connecting belt 200. The length adjustment device can adopt a technology known in the art, and a detailed description thereof is omitted herein.

[0128] 21 shows the state where the anchor joint 210 is not engaged to the storage engagement rod 183 so as to clearly show the storage engagement rod 183. The anchor joint 210 may be provided with an automatic or manual operation structure known in the art so that the engagement hook 211 is engaged to the storage engagement rod 183.

[0129] The end portion of the receiving engagement rod 184 connected to the outer side wall of the receiving groove 183 is thicker than the middle portion of the receiving engagement rod 184 to increase the strength of the receiving engagement rod 184 .

[0130] A second embodiment of a position-limiting member 300 according to the present application will be described with reference to Figures 23 to 25 . The position-limiting member 300 of the second embodiment is similar to the first embodiment. The difference between the two embodiments is that the second embodiment further includes a clamp 410 on the base 100 and a clamp slot 420 that can be covered by the clamp 410.

[0131] Specifically, the clamp 410 is disposed on the base 100 and is rotatable about a transverse axis relative to the base 100 between a closed position shown in Figures 23 and 24 and an open position shown in Figure 25. When the clamp 410 is in the closed position, it adheres to the base 100 and covers at least a portion of the clamp slot 420, the retaining member 300, and the connecting strap 200. When the clamp 410 is in the open position, it rises from the base 100 and exposes the clamp slot 420, the retaining member 300, and the connecting strap 200.

[0132] The clamp groove 420 is a groove formed by being recessed downward from the upper surface 181 of the base 100. The two end portions 301 of the retaining member 300 are fixed to the clamp groove 420, forming a retaining channel between the middle section 302 and the bottom surface 421 of the clamp groove 420. More specifically, the bottom surface 421 of the clamp groove 420 is provided with two clamp groove retaining holes 422. The two end portions 301 of the retaining member 300 are respectively fixed to the two clamp groove retaining holes 422, thereby stably securing the retaining member 300 to the clamp groove 420. Thanks to the clamp groove 420 and the clamp 410, the connecting strap 200 is more stably retained to the base 100.

[0133] Although preferred embodiments are shown and described herein, it should be understood that these embodiments are provided as examples only. Those skilled in the art will appreciate that many modifications, variations, and substitutions will occur without departing from the spirit of the present invention. Therefore, the appended claims are intended to cover all such modifications that fall within the spirit and scope of the present invention.
