Description

Technical Field

[0001] This application relates to a child safety seat. Background Technology

[0002] Child safety seats are typically installed in vehicles such as cars to provide a safe and comfortable riding environment for children. To securely install a child safety seat in a car, it usually consists of a base and a carrier (such as a seat or bassinet) attached to the base. The base is used to mount the seat to the car, and the carrier is for the child to sit in. Furthermore, because the seat is detachable from the base, the user can easily remove the carrier and child together from the base when moving the child. Existing child safety seats have a large number of base parts, especially in the connection structure between the base and the carrier, causing an unnecessary increase in weight. Therefore, there is a need to provide a new connection structure to reduce the number of parts.

[0003] On the other hand, it is desirable for the base of the child safety seat to have an adjustment mechanism to allow for adjustment of the angle between the base and the car seat. Furthermore, it is desirable that this adjustment mechanism of the base has a design that is easy for the user to operate.

[0004] On the other hand, child safety seats typically feature a connecting strap to attach the base to the car seat. In some designs, the connecting strap extends from above the base of the child safety seat, through the base, and below the base to connect to the car seat. In such cases, it is desirable to provide a limiting device to restrict the range of movement of the connecting strap relative to the base. Furthermore, it is desirable for the base of the child safety seat to provide a storage function to properly store the connecting strap and its anchoring connector when the connecting strap is not attached to the car seat.

[0140] While this invention has been illustrated and described with reference to specific embodiments, it should not be limited to the details shown. Rather, various modifications to these details may be made within the scope of equivalents of the claims without departing from the invention.

[0141] The descriptions of directions such as "front", "back", "up" and "down" in this article are for ease of understanding only. This utility model is not limited to these directions, but can be adjusted according to the actual situation.

[0142] Reference Figures 1 to 2 Overall description of the base 100 of the child safety seat according to this application.

[0143] 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 a single integral part, and therefore the upper cover 101 and the lower cover 102 are collectively referred to as the body of the base 100. The components disposed on the upper cover 101 or the lower cover 102 as described below can all be understood as being disposed on the body of the base 100.

[0144] The rear end of base 100 (i.e. Figure 1 and Figure 2 The base 100 (right side) rests against the back of the car seat. A top rod 103 is provided at the rear end of the base 100, specifically located at the upper rear end of the upper cover 101. The top rod 103 rests against the back of the car seat to ensure stable installation of the base 100 into the car. The upper cover 101 of the base 100 has a first connecting groove 104 and a second connecting groove 105 extending laterally, arranged longitudinally (i.e., in the front-to-back direction).

[0145] 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 respectively at least partially disposed in the base 100 and are exposed above the top cover 101 through the first connecting groove 104 and the second connecting groove 105, respectively.

[0146] A release element 130 is provided at the front of the base 100. The user can control the first connector 110 and the second connector 120 through the release element 130, which will be described in detail below.

[0147] Reference Figure 3A In this embodiment, the second connecting groove 105 is recessed vertically downward from the upper surface of the cover 101, and is divided into two segments arranged laterally. That is, the two segments of the second connecting groove 105 are respectively disposed on the left and right sides of the base 100. In this embodiment, two second connectors 120 are respectively disposed at the two segments of the second connecting groove 105. In other embodiments, the second connecting groove 105 is a continuous segment extending across the entire lateral dimension of the cover 101, and one or more second connectors 120 can be disposed at any lateral position of the second connecting groove 105.

[0148] Reference Figure 3B In this embodiment, the first connecting groove 104 is recessed vertically downward 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 connector 110 is disposed at the lateral middle position of the first connecting groove 104. In other embodiments, a single first connector 110 may be disposed on one lateral side of the first connecting groove 104, or multiple first connectors 110 may be distributed laterally along the first connecting groove 104.

[0149] Reference Figure 4 and Figure 5Describes a child safety seat carrier 500 according to this application. The carrier 500 has a seating section 510 for a child to sit in and a first crossbar 520 and a second crossbar 530 located on the lower surface of the seating section 510. The first crossbar 520 and the second crossbar 530 are respectively insertable into a first connecting slot 104 and a second connecting slot 105 of a base 100 and are respectively locked by a first connector 110 and a second connector 120 (see...). Figure 2 This allows the vehicle 500 to be securely attached to the base 100.

[0150] In this embodiment, the carrier 500 is in the form of a sleeping basket. In other embodiments, the carrier 500 may also be in the form of a seat or other suitable form, as long as it has a first crossbar 520 and a second crossbar 530 for engagement with the base 100.

[0151] Reference Figures 6 to 8 Further description of the base 100 of the child safety seat according to this application. Figures 6 to 8 The upper cover 101 of the base 100 is hidden in the middle, thus fully showing the release member 130, the first connector 110, the second connector 120, and also showing the sliding member 140, at least one linkage member 150, the fixed 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 disposed on the base 100.

[0152] Generally, the first connector 110 and the second connector 120 are operably engaged with the vehicle 500. That is, the first connector 110 and the second connector 120 can be switched between a locked position and an unlocked position to lock or unlock the vehicle 500 (specifically, the first crossbar 520 and the second crossbar 530 at the bottom of the vehicle 500, see...). Figure 5 ).

[0153] The release element 130 is exposed outside the base 100 for user operation. A slider 140 is connected to the release element 130 and can be driven by the release element 130 to release the carrier 500 via the first connector 110. A linkage 150 is connected between the slider 140 and the second connector 120 and can be driven by the slider 140 to release the carrier 500 via the second connector 120.

[0154] In this embodiment, the first connector 110 and the second connector 120 are respectively disposed on the upper cover 101. The locking member 130, the sliding member 140, and the linkage member 150 are respectively disposed on the lower cover 102. However, as mentioned above, the upper cover 101 and the lower cover 102 can be a whole, so the above-mentioned components are actually disposed on the body composed of the upper cover 101 and the lower cover 102.

[0155] Specifically, the release element 130 is rotatably connected to the front end of the body of the base 100 (specifically, the front end of the lower cover 102) via a release element shaft 195, so as to rotate relative to the body of the base 100 about a transverse axis. The release element 130 includes a release portion 131 and a release slide 132. The release portion 131 can be operated from outside the base 100 to rotate the release element 130 relative to the body of the base 100. For example, the release portion 131 can be a handle with an arcuate profile to provide a good appearance and operating experience. The release slide 132 is connected to the first end 141 (specifically, the front end) of the slider 140. More specifically, referring to reference... Figure 10A The release groove 132 is a linear or curved groove 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 groove 132, so when the release member 130 rotates relative to the body of the base 100, the release pin 133 moves longitudinally while sliding along the release groove 132, thereby causing the slider 140 to slide longitudinally, so that the rotation of the release member 130 relative to the body is converted into the sliding of the slider 140 along the body.

[0156] The main body of the slider 140 is a generally longitudinally extending T-shaped plate. Its front end 141 (the foot of the T-shape) is connected to the release member 130, and its rear end 142 (the head of the T-shape) 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 away from the transverse portion 145 is connected to the release member 130, and the two ends of the transverse portion 145 are respectively connected to the two linkage members 150. The longitudinal portion 144 has a vertically penetrating opening 144a, through which the first connecting member 110 extends, so that the sliding of the slider 140 does not hinder the rotation of the first connecting member 110.

[0157] 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 drive portion 143 connected to a first drive rod 196. In this embodiment, the drive portion 143 is a downwardly extending and forward-opening recess to engage the first drive rod 196 and drive it to move longitudinally. More specifically, the drive portion 143 is disposed between the two ends of a 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 drive portion 143 and the first drive rod 196, and the release pin 133, are both located below the longitudinal portion 144 and have approximately the same height vertically. The contact point between the drive portion 143 and the first drive rod 196, and the release pin 133, are both approximately located at the lateral center of the base 100. In other words, the contact point between the drive unit 143 and the first drive rod 196 is approximately aligned with the release pin 133 in both the lateral and vertical directions, and is only spaced apart in the longitudinal direction. This allows the driving force of the release pin 133 to be accurately transmitted to the first drive rod 196 in the longitudinal direction through the slider 140, without easily generating lateral or vertical component forces. In other embodiments, the drive unit 143 can be in any suitable form, such as a ring or lever, as long as it can drive the first drive rod 196 to move in the longitudinal direction.

[0158] The first connector 110 is rotatably connected to the body of the base 100 via a laterally extending first shaft 193, specifically to the upper cover 101 of the base 100. Although Figures 6 to 8 The upper cover 101 is not shown, but it should be understood that the upper cover 101 has a connecting structure so that both ends of the first shaft 193 can be inserted therein. (Refer to reference...) Figures 6 to 8 and Figure 10A The upper end of the first connector 110 is a forward-opening first hook portion 111, and the lower end of the first connector 110 is connected to the first drive rod 196. The first drive rod 196 is arranged parallel to the first shaft 193 and located below the first shaft 193. Therefore, the first hook portion 111 and the first drive rod 196 are located on opposite sides of the first shaft 193. The first connector 110 is along... Figure 10A Rotating counterclockwise is equivalent to rotating toward the locking direction. Figure 10A Rotating clockwise in the middle means rotating in the direction of unlocking.

[0159] When the slider 140 slides relative to the body of the base 100, the drive unit 143 drives the first connecting member 110 via the first drive rod 196 to release the carrier 500. Specifically, the slider 140 slides forward under the drive of the release member 130, and the drive unit 143 of the slider 140 drives the first drive rod 196 to move forward. The forward-moving first drive rod 196 drives the first connecting member 110 along... Figure 10ARotating clockwise in the middle means rotating in the direction of unlocking, so that the first connecting member 110 rotates to the unlocking position.

[0160] The first retaining member 191 applies a biasing force to the first connecting member 110, the direction of which is opposite to the direction in which the sliding member 140 slides as driven by the releasing member 130. Specifically, the first retaining member 191 is disposed between the body of the base 100 and the first drive rod 196, holding the first connecting member 110 in a position that tends to engage with the carrier 500. The first retaining member 191 can be configured as a tension spring, with its two 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 keeping the first connecting member 110 in the locked position.

[0161] Combined with reference Figures 6 to 8 and Figure 10B In this embodiment, the linkage 150 is a generally longitudinally extending elongated rod, with both its front end 151 and rear end 152 being annular. The front end 151 of the linkage 150 is fitted onto the second end 142 of the slider 140, which is a laterally extending rod, for example, extending laterally to the left and right sides respectively, so that the front ends 151 of the two linkages 150 can be pivotally fitted onto the lateral sides of the second end 142 respectively. The rear end 152 of the linkage 150 is fitted onto the second drive rod 197, which is connected to the second connector 120. Therefore, when the slider 140 slides forward relative to the base 100, the slider 140 drives the second drive rod 197 to move forward via the linkage 150.

[0162] The second connector 120 is rotatably connected to the body of the base 100 via the second shaft 194, specifically to the fixing seat 155, which 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 opening second hook portion 121. The second connector 120 is connected to the second drive rod 197 at a position between the second hook portion 121 and the second shaft 194. The second drive rod 197 is parallel to the second shaft 194 and located above it. That is, unlike the first connector 110, the second drive rod 197 and the second hook portion 121 are located on the same side of the second shaft 194. The second connector 120... Figure 10B Rotating clockwise in the middle means rotating towards the locking direction. Figure 10B Rotating counterclockwise is the same as rotating in the direction of unlocking.

[0163] When the sliding member 140 drives the second drive rod 197 forward via the linkage member 150, the second drive rod 197 drives the second connecting member 120 to rotate counterclockwise, that is, to rotate in the unlocking direction, so that the second connecting member 120 rotates to the unlocking position.

[0164] The second retainer 192 applies a biasing force to the second drive rod 197, the direction of which is opposite to the direction in which the slider 140 slides as driven by the release member 130. Specifically, the second retainer 192 is disposed between the body of the base 100 and the second drive rod 197, holding the second connector 120 in a position tending towards locking the carrier 500. The second retainer 192 can be configured as a tension spring, with its two ends connected to the body of the base 100 and the second drive rod 197 respectively, to apply a rearward pulling force to the second drive rod 197, thereby keeping the second connector 120 in the locked position.

[0165] In this embodiment, the front ends 151 of the two linkage members 150 are respectively connected to the lateral ends of the slider 140, and the rear ends 152 of the two linkage members 150 are respectively connected to the corresponding second drive rods 197. The two second drive rods 197 are respectively connected to the two second connectors 120, and the rear ends 152 of the two linkage members 150 are located between the two second connectors 120. In other embodiments, a single linkage member 150 may be provided, with its front end 151 connected to the slider 140 and its rear end 152 connected to a single second drive rod 197. Furthermore, the single second drive rod 197 may be connected to two second connectors 120, for example, extending laterally between the two second connectors 120.

[0166] According to this application, when the slider 140 is driven to slide by the release member 130, 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. Correspondingly, when the slider 140 is not driven to slide by the release member 130, the first hook portion 111 and the second hook portion 121 rotate in opposite directions under the bias of the first retainer 191 and the second retainer 192 to lock the carrier 500. (Refer to reference...) Figure 3A and Figure 3B When the first connector 110 and the second connector 120 are in the locked position, the first hook 111 and the second hook 121 are exposed above the base 100 through the first connecting groove 104 and the second connecting groove 105, respectively, and cooperate with the first connecting groove 104 and the second connecting groove 105 to form a closed space to lock the first crossbar 520 and the second crossbar 530 (not shown).

[0167] Thanks to the base 100 structure of this 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 a base 100 structure using multiple first connectors 110.

[0168] Reference Figures 11 to 12BThe overall description of the adjustment structure according to this application includes an adjustment component 160, an operating component 170, and a locking component 175.

[0169] In this embodiment, the adjusting member 160 is a foot pad located at the lower rear end 152 of the base 100, which can... Figure 12A The retraction position shown is the same as Figure 12B The extension position can be moved between the indicated positions to adjust the pitch angle of the base 100 relative to the vehicle seat (not shown). For example, when the adjustment member 160 is in... Figure 12A When the adjustment element 160 is in the retracted position as shown, the lower surface of the adjustment element 160 is substantially flush with the lower surface of the base 100 body, so the base 100 is placed horizontally on the car seat, making the base 100 (and the entire child safety seat) roughly horizontal. When the adjustment element 160 is in... Figure 12B In the extended position shown, the lower surface of the adjuster 160 is tilted rearward and downward relative to the body of the base 100, thus raising the rear end of the base 100 and causing the base 100 (and the entire child safety seat) to tilt forward. The footrest can be in several different extended positions to allow the base 100 to be set to different pitch angles. Figure 12B Only one of the protrusion positions is shown.

[0170] In other embodiments, the adjustment member 160 may be located at other suitable locations on the child safety seat, such as the rear surface, side surface, etc., to adjust the angle of the child safety seat in different directions.

[0171] The engaging member 175 is located at the rear of the base 100 and is capable of holding the adjusting member 160 in the extended or retracted position. The operating member 170 is located at the rear of the base 100 and is at least partially exposed behind the base 100 so that the user can operate the engaging member 175 to hold or release the adjusting member 160.

[0172] Reference Figure 14A and 14B Further describe the structural adjustments.

[0173] One end of the adjusting member 160 is rotatably connected to the body of the base 100. Specifically, the front end of the adjusting 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 adjusting member 160 has at least one stop portion 164 arranged along the rotation direction of the adjusting member 160, each stop portion 164 corresponding to an extended position or a retracted position. The stop portion 164 is specifically a hook extending rearward and opening downward. A first elastic element 198, for example a compression spring, is provided between the body of the base 100 (specifically the lower cover 102) and the adjusting member 160 to bias the adjusting member 160 toward the extended position.

[0174] Combined with reference Figure 14A , Figure 14B and Figure 15 The engaging member 175 can engage with either stop 164 to hold the adjusting member 160 in the extended or retracted position. Specifically, the engaging member 175 is rotatably connected to the base 100, and in the side sectional view (i.e. Figure 14A The device is approximately L-shaped. 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 located at both 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 part 171 so that it can be driven by the operating part 171. The engaging portion 177 is located at the lower end of the engaging member 175 and can engage with the stop portion 164 of the adjusting member 160.

[0175] 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 adjustment 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 portion 176.

[0176] In this embodiment, the adjusting member 160 and the engaging member 175 rotate about the transverse axis relative to the body of the base 100, and the engaging portion 177 extends laterally to facilitate the compactness of the adjustment structure. In other embodiments, the adjusting member 160 and the engaging member 175 may also be configured in other suitable forms, such as linearly moving relative to the base 100.

[0177] The operating element 170 includes an operating portion 171 and a drive rod 172. The operating portion 171 can be operated from outside the base 100, for example, in the form of a handle. The drive rod 172 engages with 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 drive rod 172 is, for example, a rod extending laterally to stably engage with the arm 176.

[0178] 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 move towards the base 100 under the action of the second elastic member 199. Figure 14A Rotating clockwise causes the engaging portion 177 to engage any stop portion 164 of the adjusting member 160, thereby holding the adjusting member 160 in the retracted or extended position.

[0179] 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 against the bias of the second elastic member 199, causing the engaging member 175 to move around... Figure 14A The device rotates counterclockwise, causing the engaging portion 177 to move away from the adjusting member 160 and disengage from the stop portion 164. At this time, the adjusting member 160 tends to move towards the extended position under the bias of the first elastic member 198, and the user can press down on the base 100 relative to the car seat (or other surface where the base 100 is located) to move the adjusting member 160 to the retracted position. Then, the user releases the operating member 170, causing the engaging member 175 to hold the adjusting member 160 in position again.

[0180] Thanks to the adjustment structure of this application, the adjustment member 160 can be held or released by the linearly moving operating member 170.

[0181] Combined with reference Figures 16 to 18B The assembly relationship between the adjustment component 160 and the base 100 is further described.

[0182] Adjustment member 160 is connected to the body of base 100 via a first pivot 162 and a second pivot 163, which are opposite to each other. The first pivot 162 is cylindrical, and the second pivot 163 includes a pivot shaft 163a, an extension 163b, and a protrusion 163c. The pivot shaft 163a extends opposite to the first pivot 162. The extension 163b extends radially outward from the outer peripheral surface of the pivot shaft 163a. ​​The protrusion 163c extends from the end of the extension 163b away from the pivot shaft 163a and is located on both sides of the extension 163b, respectively, as the pivot shaft 163a.

[0183] The body of the base 100 has a circular hole 107 on one side connected to the adjusting member 160, and a shaped groove 106 on the opposite side. The shaped groove 106 is configured to allow the second pivot 163 to slide from outside the base 100 into the shaped groove 106 when the first pivot 162 of the adjusting member 160 is inserted into the circular hole 107, and to keep the pivot axis 163a of the second pivot 163 rotating in the shaped groove 106.

[0184] More specifically, the irregular groove 106 includes a guide portion 106a and a receiving portion 106b. The guide portion 106a extends vertically to the outside of the base 100 and engages the protrusion 163c of the second pivot portion 163 to prevent the second pivot portion 163 from disengaging from the irregular groove 106. The receiving portion 106b extends longitudinally from the guide portion 106a and receives the pivot shaft 163a of the second pivot portion 163.

[0185] During the process of assembling the adjustment part 160 into the body of the base 100, the first pivot part 162 is first inserted into the circular hole 107, and then the pivot shaft 163a of the second pivot part 163 is moved into the receiving part 106b through the guide part 106a of the irregular groove 106, which facilitates the easy assembly of the adjustment part 160.

[0186] Reference Figure 19 A first embodiment of the limiting member 300 according to this application is described.

[0187] The child safety seat includes a connecting strap 200 for connecting a 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), and the connecting strap 200 passes over the base 100 from above to below the base 100. Figure 19 (below) and connected to the vehicle seat, thereby installing the base 100 to the vehicle seat.

[0188] In this embodiment, the middle section of the connecting strap 200 is connected to the upper part of the base 100, and both ends of the connecting strap 200 pass through the base 100 and reach the bottom of the base 100.

[0189] The base 100 is provided with a through-hole 182 that penetrates the base 100, and the connecting strap 200 can pass through the through-hole 182 from the upper surface 181 of the base 100 to the bottom of the base 100. In this embodiment, the two through-holes 182 are respectively provided on the lateral sides of the base 100 so as to allow both ends of the connecting strap 200 to pass through the base 100 respectively.

[0190] It should be understood that the connecting strap 200 is not fixed to the base 100, but can slide relative to the base 100. To limit the longitudinal sliding range of the connecting strap 200 relative to the base 100, and particularly to prevent excessive longitudinal sliding of the connecting strap 200 relative to the base 100 that could obstruct the second connecting member 120 (see... Figure 2 The base 100 is provided with a limiting channel for the connecting belt 200 to pass through. The limiting channel movably connects the connecting belt 200 to the base 100 and is located between two through holes 182.

[0191] Specifically, the limiting channel is provided by a limiting member 300 disposed on the base 100. The limiting member 300 is a strip or plate that intersects with the connecting strip 200. For example, the connecting strip 200 extends laterally, and the limiting member 300 extends longitudinally, thus intersecting with the connecting strip 200. The limiting member 300 has two ends 301 and an intermediate section 302 located between the two ends. The two ends 301 are connected to the upper surface 181 of the base 100, such that a limiting channel is formed between the intermediate 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 strip 200, thereby preventing the connecting strip 200 from sliding longitudinally up and down relative to the base 100 within the limiting channel.

[0192] Combined with reference Figure 19 and Figure 20 In this embodiment, the upper surface 181 of the base 100 is provided with two upper surface limiting holes 181a, and the two ends 301 of the limiting member 300 are respectively fixed to the two upper surface limiting holes 181a. More specifically, the two ends 301 of the limiting member 300 pass through the two upper surface limiting holes 181a from above, and are knotted below the upper surface 181 to fix them to the upper surface. In other embodiments, the two ends 301 of the limiting member can be fixed to the upper surface 181 of the base 100 in other ways, such as by means of buckles, wrapping, or Velcro.

[0193] Reference Figure 21 and Figure 22 The two ends of the connecting strap 200 pass through the through-holes 182 located on both sides of the base 100 and extend to the bottom of the base 100. Anchoring connectors 210 are provided at each of the two ends of the connecting strap 200. The anchoring connectors 210 can engage with corresponding accessories (not shown) on the vehicle seat, allowing the base 100 to be installed onto the vehicle seat. A storage structure is provided at the bottom of the base 100 to store the connecting strap 200 and the anchoring connectors 210 when the base 100 is not connected to the vehicle seat using the connecting strap 200.

[0194] Specifically, the base 100 has a storage groove 183 at its bottom, which can accommodate at least one of the connecting strap 200 and the anchoring connector 210. More specifically, the storage groove 183 is a groove formed by an upward indentation from the bottom surface of the base 100. Two storage grooves 183 are respectively provided on the lateral sides of the base 100 and extend approximately longitudinally. Figure 21 The diagram schematically illustrates the state in which the connecting strap 200 is folded and stored in the storage slot 183. It should be understood that the connecting strap 200 may be a flexible strap and therefore may be rolled, folded, or twisted in order to be stored in the storage slot 183.

[0195] Two anchoring joints 210 are respectively connected to both ends of the connecting strap 200. The anchoring joints 210 are, for example, in the form of a snap-fit ​​and have engagement hooks 211 for connecting to the vehicle seat.

[0196] A receiving groove 183 is provided with a receiving connecting rod 184, and the connecting hook of the anchoring connector 210 can engage with the receiving connecting rod 184. Specifically, the receiving connecting rod 184 extends approximately laterally and is located at the opening of the receiving groove 183. Therefore, when the connecting strap 200 is received in the receiving groove 183, the anchoring connector 210 can easily engage with the receiving connecting rod 183. In this embodiment, two receiving connecting rods 184 are respectively provided in the receiving grooves 183 located on both sides of the lateral side of the base 100, and these two receiving connecting rods 184 are provided at different longitudinal positions of the base 100. That is, the distance between the receiving connecting rod 184 on one side and the through-hole 182 is greater than the distance between the receiving connecting rod 184 on the other side and the through-hole 182, or in other words, the position of the receiving connecting rod 184 on one side is closer to the front of the base 100 than the receiving connecting rod 184 on the other side (i.e., Figure 21 (Lower left side). On the side with a larger distance between the receiving connecting rod 184 and the through-hole 182, more storage space is provided for the connecting strap 200, so that the length adjustment device (not shown) of the connecting strap 200 can be housed. This length adjustment device can employ techniques known in the art, and a detailed description thereof is omitted herein.

[0197] Figure 21 The image shows the anchoring connector 210 not engaged with the receiving engagement rod 183, so as to clearly show the receiving engagement rod 183. The anchoring connector 210 may be provided with an automatic or manual operation structure known in the art, so that the engagement hook 211 engages with the receiving engagement rod 183.

[0198] The end of the receiving connecting rod 184 that connects to the outer wall of the receiving groove 183 is thicker than the middle part of the receiving connecting rod 184 to increase the strength of the receiving connecting rod 184.

[0199] Reference Figures 23 to 25 A second embodiment of the limiting member 300 according to this application is described. The limiting member 300 of the second embodiment is similar to that of the first embodiment. The difference between the two embodiments is that the second embodiment also provides a base 100 with a clamp 410 and a clamp groove 420 that can be covered by the clamp 410.

[0200] Specifically, the clamp 410 is disposed on the base 100 and is capable of moving relative to the base 100 about a transverse axis. Figure 23 , Figure 24 The closed position shown is the same as Figure 25The clamp 410 rotates between the shown open positions. When the clamp 410 is in the closed position, it conforms to the base 100 and covers at least a portion of the clamp slot 420, the stop 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 stop 300, and the connecting strap 200.

[0201] The clamp groove 420 is a groove formed by recessing downwards from the upper surface 181 of the base 100. The two ends 301 of the limiting member 300 are fixed to the clamp groove 420, forming a limiting 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 limiting holes 422. The two ends 301 of the limiting member 300 are respectively fixed to the two clamp groove limiting holes 422, so that the limiting member 300 is stably fixed to the clamp groove 420. Thanks to the clamp groove 420 and the clamp 410, the connecting strap 200 is more stably held to the base 100.

[0202] While preferred embodiments have been shown and described herein, it should be understood that these embodiments are given by way of example only. Many variations, modifications, and substitutions will occur to those skilled in the art without departing from the spirit of this invention. Therefore, the appended claims are intended to cover all such variations that fall within the spirit and scope of this invention.
