Description

[0001] Child safety seats

[0002] Technical Field

[0003] This disclosure relates to a child vehicle, and more particularly to a child safety seat.

[0004] Background Technology

[0005] Child safety seats provide a comfortable and safe sitting and lying space for children when traveling. Generally, child safety seats can be used in both forward-facing and rear-facing positions to accommodate the needs of children of different sizes and maximize their safety. In order to prevent the child safety seat from overturning in the event of an accidental collision, child safety seats are generally equipped with a top tether. However, when using a rear-facing child safety seat, the two webbing straps of the top tether are located on the left and right sides of the child safety seat, which hinders the child from getting in and out of the child safety seat and causes inconvenience.

[0006] In addition, a reinforcing structure is installed between the child safety seat and the top harness (also known as the "top leash") to enhance the connection's strength. Existing reinforcing structures are often complex and inconvenient to use.

[0131] Detailed Implementation

[0132] 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 and without departing from the invention.

[0133] The directional descriptions such as "F" (front), "B" (back), "L" (left), "R" (right), "T" (up), and "D" (down) mentioned in this document can be found in the accompanying drawings. These descriptions are for ease of understanding only. This invention is not limited to these directions but can be adjusted according to actual circumstances. Although this application has been described with reference to typical embodiments, the terminology used is illustrative and exemplary, not restrictive.

[0134] Figure 1 shows a perspective view of a child safety seat 100 mounted forward on a vehicle seat 200 according to an embodiment. The vehicle seat 200 includes a seating portion 210 and a backrest 220 located above the seating portion 210, wherein the seating portion 210 is located in front of the backrest 220 in the fore-aft direction (the front, rear, left, and right of the vehicle, vehicle seat 200, and child safety seat 100 are defined with reference to the vehicle's forward direction), the seating portion 210 is used to support the child safety seat 100 upward, and the backrest 220 is used to abut against the child safety seat 100 forward.

[0135] As shown in Figures 1 and 3, the child safety seat 100 includes a seat body 1000 for a child to sit in, a harness assembly 2000 connecting the seat body 1000 to the vehicle, and a base 3000 located below the seat body 1000. The base 3000 is placed on the seating section 210 and can be detachably connected to the vehicle seat 200 via a fastening device (e.g., ISOFIX) not shown. When the base 3000 is connected to the vehicle seat 200, the base 3000 is fixed relative to the vehicle seat 200, but the seat body 1000 can rotate relative to the base 3000 so that the child safety seat 100 is in a forward-facing or rear-facing position. When the child safety seat 100 is installed on the vehicle seat 200 and is in the forward-facing position, the child can face forward after sitting in the seat body 1000. When the child safety seat 100 is installed in the vehicle seat 200 and is in the rear-facing position, the seat body 1000 rotates horizontally by 180 degrees relative to the forward-facing position. After the child sits in the seat body 1000, he / she can face the rear of the vehicle, as shown in Figure 3, specifically facing the backrest 220 of the vehicle seat 200.

[0136] As shown in Figures 1 and 2, the seat body 1000 includes a seat portion 1100 that contacts the lower body of a child, a backrest portion 1200 that contacts the upper body of a child, and a headrest portion 1300 that contacts the head of a child. Whether in a forward-facing or rear-facing use position, the backrest portion 1200 and the headrest portion 1300 are located above the seat portion 1100, and the headrest portion 1300 and the seat portion 1100 are located on the same side of the backrest portion 1200 in the front-back direction. In the forward-facing use position, the seat portion 1100 is in the front, while the backrest portion 1200 is in the rear, meaning the backrest portion 1200 is closer to the backrest 220 of the vehicle seat 200 than the seat portion 1100. As shown in Figure 3, in this rearward use state, the seat 1100 is located at the rear, while the backrest 1200 is located at the front. That is, the seat 1100 is closer to the backrest 220 of the vehicle seat 200 than the backrest 1200. According to this disclosure, the strap assembly 2000 is used to connect the seat body 1000 to an anchor point (not shown) of the vehicle, whether in the forward or rearward use state. The anchor point is generally located at the rear of the backrest 220 of the vehicle seat 200. By connecting the seat body 1000 to the vehicle anchor point rearward through the strap assembly 2000, the seat body 1000 is prevented from tipping forward when the vehicle brakes or a collision occurs, thus avoiding danger to children riding in the seat body 1000. As shown in Figures 1 and 2, the backrest 1200 includes a main body 1210 and a connecting portion 1220 located on the upper side of the main body 1210. The main body 1210 is used to abut against the child's back and laterally protect the child's upper body in the left and right directions to avoid impacts from the left and right directions. The main body 1210 also includes two side wings 1230 located on the left and right sides of the main body 1210. The two side wings 1230 laterally protect the child's upper body in the left and right directions to avoid impacts from the left and right directions. According to this embodiment, the connecting portion 1220 extends in the left and right direction, and its two ends are respectively connected to the main body 1210, while the remaining part is spaced apart from the main body 1210, thereby forming a hollow portion 1260a between the connecting portion 1220 and the main body 1210. The connecting portion 1220 is used to connect with the harness assembly 2000 and can also be used as a handle for carrying the child safety seat 100. In another embodiment, the connecting portion 1220 may also be disposed on the side of the main body portion 1210 away from the seat portion 1100 in the front-back direction, instead of being disposed on the upper side of the main body portion 1210, and the hollow portion 1260a formed between the connecting portion 1220 and the main body portion 1210 is located on the side of the main body portion 1210 away from the seat portion 1100 in the front-back direction.In another embodiment, the connecting portion 1220 may also be continuously connected to the main body portion 1210 in the left-right direction, rather than only its left and right ends being connected to the main body portion 1210, and the connecting portion 1220 itself forms the aforementioned hollow portion 1260a for connection with the strap assembly 2000.

[0137] As shown in Figures 1 and 2, the seat 1100 is designed to abut against the child's buttocks and provide lateral protection to the child's lower body in the left and right directions to prevent impacts from these directions. The seat 1100 also includes two side wings 1230 located on the left and right sides of the seat 1100, which provide lateral protection to the child's lower body in the left and right directions to prevent impacts from these directions.

[0138] As shown in Figures 1 and 2, the lacing assembly 2000 includes a lacing body 2100 and an anchoring portion 2200. The lacing body 2100 connects the seat body 1000 and the anchoring portion 2200, which is used to connect to the vehicle's anchoring point. Both ends of the lacing body 2100 are connected to the seat body 1000, and the anchoring portion 2200 is located between the two ends of the lacing body 2100 and can slide along the lacing body 2100. According to this embodiment, one end of the anchoring portion 2200 is, for example, a hook used to hook onto the vehicle's anchoring point, and the other end has a through hole through which the lacing body 2100 can pass to connect with the anchoring portion 2200. The anchoring portion 2200 serves as a boundary, defining a first segment 2110 and a second segment 2120 of the strap body 2100; that is, the first segment 2110 and the second segment 2120 are located on either side of the anchoring portion 2200. The lengths of the first segment 2110 and the second segment 2120 can be adjusted by moving the anchoring portion 2200. According to this disclosure, the strap assembly 2000 can, for example, be formed from a single piece of fabric or composed of multiple pieces of fabric.

[0139] As shown in Figure 2, on the side away from the anchoring portion 2200, the first segment 2110 has a first end 2111 (i.e., one end of the strap body 2100), and the second segment 2120 has a second end 2121 (i.e., the other end of the strap body 2100). The first end 2111 and the second end 2121 are respectively connected to the backing portion 1200, specifically to the connecting portion 1220 of the backing portion 1200. Preferably, the first end 2111 and the second end 2121 are configured as collars 2111 and 2121 that are fitted onto the connecting portion 1220. Specifically, the first end 2111 and the second end 2121 bypass the connecting portion 1220 and are joined by a joining portion 2112 to form collars 2111 and 2121. The joining portion 2112 is, for example, a stitch. As can be seen from the above, the first end 2111 and the second end 2121 are partially disposed in the hollow portion 1260. The collar 211L2121 formed by the first end 2111 and the second end 2121 is not tightly attached to the connecting portion 1220, but has a gap. This gap is sufficient to allow the first end 2111 and the second end 2121 to slide along the connecting portion 1220 when the strap body 2100 is in a relaxed state.

[0140] As shown in Figures 2, 3, 8 and 9, the strap assembly 2000 also includes an adjustment member 2300 for the strap body 2100 to pass through. The adjustment member 2300 is used to adjust the overall length of the first section 2110 and the second section 2120. Specifically, taking the adjusting member 2300 as the boundary, the strap body 2100 can be further divided into a first strap 2500 and a second strap 2600. The first strap 2500 is a portion of the second segment 2120, and the second strap 2600 includes a portion of the second segment 2120 and the entire first segment 2110. One end of the first strap 2500 (i.e., the second end 2121) is connected to the connecting part 1220, and the other end of the first strap 2500 is connected to the adjusting member 2300. One end of the second strap 2600 (i.e., the first end 2111) is connected to the connecting part 1220, and the other end of the second strap 2600 is wrapped around the adjusting member 2300 to form a free end 2400. By pulling the free end 2400, the extension length of the strap body 2100 between the first end 2111 and the second end 2121, i.e., the first segment 2110, can be adjusted. The overall length of the second segment 2120. In this embodiment, it is known that the adjusting member 2300 is located at the second segment 2120 ±o. In other embodiments, the adjusting member 2300 may also be located at the first segment 2110 ±o. In other embodiments, the adjusting member 2300 may not be provided.

[0141] As shown in Figures 8 and 9, the adjusting member 2300 has two connecting shafts 2310, located on both sides of the adjusting member 2300, and connected to the other ends of the first strap 2500 and the second strap 2600, respectively. The other end of the first strap 2500 passes over one of the connecting shafts 2310 and is joined by a joint 2510 to form a collar 2520. This joint 2510 is, for example, a stitch. One end of the first strap 2500 is the second end 2121. Thus, the two ends of the first strap 2500 form collars 2121 and 2520, respectively. The other end of the second strap 2600 passes over the other connecting shaft 2310 and extends out of the adjusting member 2300 to form the free end 2400. One end of the second strap 2600 is the first end 211L, forming a collar 2111.

[0142] As shown in Figure 1, in the forward-facing usage state, the first end 2111 and the second end 2121 are located on the left and right sides of the connecting part 1220 near its left and right ends (the left and right sides of the connecting part 1220 are divided by the center line I of the connecting part 1220 in the left and right direction), and are also located on the left and right sides of the backrest 1200 and the left and right sides of the child safety seat 100 (the left and right sides of the backrest 1200 are divided by the center line I of the backrest 1200 in the left and right direction, and the left and right sides of the child safety seat 100 are divided by the center line I of the child safety seat 100 in the left and right direction. In this embodiment, the center line I of the connecting part 1220 in the left and right direction coincides with the center line I of the backrest 1200 in the left and right direction and the center line I of the child safety seat 100 in the left and right direction).

[0143] As shown in Figure 2, in order to ensure that the first end 2111 and the second end 2121 can be stably positioned on the left and right sides of the connecting part 1220 (or the left and right sides of the child safety seat 100) in the forward-facing use state, so as to provide a more stable connection between the child safety seat 100 and the vehicle's anchoring point, the connecting part 1220 is provided with two positioning grooves 1222. The two positioning grooves 1222 are specifically provided on the left and right sides of the connecting part 1220, and both positioning grooves 1222 are recessed towards the center of the connecting part 1220 in the left and right directions, so as to receive the first end 2111 of the first segment 2110 and the second end 2121 of the second segment 2120 of the strap assembly 2000 in the left and right directions, thereby preventing the first end 2111 and the second end 2121 from sliding towards the center of the connecting part 1220 in the left and right directions, respectively.

[0144] As shown in Figures 1 and 2, when the child safety seat 100 is in forward-facing use, the two ends of the strap body 2100 (i.e., the first end 2111 and the second end 2121) are respectively located on the side of the two positioning grooves 1222 away from the middle of the connecting part 1220 in the left-right direction. At this time, the first segment 2110 and the second segment 2120 are also located on the left and right sides of the child safety seat 100, respectively. The two ends of the strap body 2100 extend backward from the backrest 1200 to the anchoring part 2200 connected to the vehicle's anchoring point. As shown in Figures 3 and 4, when the child safety seat 100 is in rear-facing use, the strap assembly 2000 extends backward from the backrest 1200 to the vehicle's anchoring point only on one side of the child safety seat 100 in the left-right direction (the left side L in Figures 3 and 4). Specifically, the strap assembly 2000 is located entirely on one side of the child safety seat 100 in the left-right direction. The strap body 2100 extends rearward from the connecting portion 1220 of the backrest 1200 to the vehicle's anchoring point. Both ends of the strap body 2100 are connected to the backrest 1200 on the same side in the left-right direction. Specifically, both ends of the strap body 2100 are located on the same positioning groove 1222 on the side away from the middle of the connecting portion 1220 in the left-right direction. That is, the first segment 2110 and the second segment 2120 are located on the same side of the child safety seat 100 in the left-right direction. When the child safety seat 100 is installed on the vehicle seat 200, the strap assembly 2000 is positioned away from the vehicle door in the left-right direction, while the side of the child safety seat 100 without the strap assembly 2000 in the left-right direction is adjacent to the vehicle door, facilitating the caregiver to put the child into or take the child safety seat 100 out from that side.

[0145] According to this disclosure, whether in the forward or backward use state, the first end 2111 and the second end 2121 are both located on the side of the positioning groove 1222 away from the middle of the connecting part 1220. At this time, the first end 2111 and the second end 2121 can be received in the positioning groove 1222 or spaced apart from the positioning groove 1222 in the left and right direction. When the anchoring part 2200 is connected to the vehicle's anchoring point, the strap body 2100 is tightened. As the first end 2111 and the second end 2121 move laterally toward the center of the connecting part 1220, the bottom of the positioning groove 1222 blocks the first end 2111 and the second end 2121, thus confining them to the side of the corresponding positioning groove 1222 away from the center of the connecting part 1220. This prevents the first end 2111 and the second end 2121 from sliding out of the corresponding positioning groove 1222 along the connecting part 1220 toward the side closer to the center of the connecting part 1220, whether in forward or rearward use.

[0146] In this embodiment, in order to switch the child seat 100 from a forward-facing use state to a rear-facing use state, it is necessary to first disconnect the connection between the anchoring part 2200 and the vehicle's anchoring point. At this time, the strap body 2100 is in a slack state. Then, the first end 2111 of the first segment 2110 or the second end 2121 of the second segment 2120 near the vehicle door side slides from the corresponding positioning groove 1222 away from the middle of the connecting part 1220 to the middle of the connecting part 1220, and then slides to another positioning groove 1222 away from the middle of the connecting part 1220, so that the first end 2111 and the second end 2121 are located on the same positioning groove 1222 away from the middle of the connecting part 1220, and the entire strap assembly 2000 is located on the same side of the child seat 100 in the left-right direction. Since the connecting part 1220 is further away from the anchor point of the vehicle seat 200 when in the rearward use state, the overall extension length of the first section 2110 and the second section 2120 can be extended by adjusting the adjusting part 2300.

[0147] As shown in Figures 3 and 4, compared with the forward use state in Figures 1 and 2, the first end 2111 of the first segment 2110 is moved from the side of the positioning groove 1222 on the left-right side of the connecting part 1220 away from the middle of the connecting part 1220 to the side of the positioning groove 1222 on the other side of the left-right side of the connecting part 1220 away from the middle of the connecting part 1220, so that it is located in the same positioning groove 1222 away from the middle of the connecting part 1220 as the second end 2121 of the second segment 2120.

[0148] As shown in Figure 2, the connecting part 1220 includes a connecting rod 122 extending in the left-right direction and a positioning member 1221a located below the connecting rod 122. The left and right ends of the connecting rod 122 are connected to the main body 1210, and the remaining portion is spaced downwards from the main body 1210. The positioning member 1221a is shorter than the connecting rod 122 in the left-right direction. The middle portion of the positioning member 1221a is connected upwards to the connecting rod 122, while the left and right ends of the positioning member 1221a are spaced apart from the connecting rod 122 in the up-down direction. The positioning member 1221a is also spaced downwards from the main body 1210. Two positioning grooves 1222 are provided in the up-down direction between the connecting rod 122 and the left and right ends of the positioning member 1221a. In this embodiment, the center line L of the positioning member 1221a, the connecting rod 122, and the connecting part 1220 coincides in the left-right direction. In other embodiments, the positioning member 1221a may also be integrally formed with the connecting part 1220, i.e., it is a one-piece structure.

[0149] Figure 5 shows a perspective view of a child safety seat 100 installed rearward according to one embodiment. Unlike Figure 4, the rear cover of the seat body 1000 is removed in Figure 5, allowing a view of the interior.

[0150] According to this embodiment, the child safety seat 100 includes a reinforcing portion 1240 located at the rear of the seat body 1000. The reinforcing portion 1240 is, for example, two reinforcing tubes, and a connecting portion 1220 is configured as a U-shaped connecting tube, connecting to the upper ends of the two reinforcing portions 1240. The reinforcing portion 1240 extends along the backrest portion 1200 to below the seat portion 1100, providing overall reinforcement to prevent deformation of the child safety seat 100.

[0151] Advantageously, the connecting portion 1220 can also be integrally formed with the reinforcing portion 1240, thereby providing better stability. Furthermore, the reinforcing portion 1240 can be provided as one or more, or in other forms, and this disclosure is not limited thereto.

[0152] Figure 5 also shows the anchoring part 2200, which also includes an elastic tongue that closes the hook, thereby preventing the anchoring part 2200 from detaching from the anchoring point on the rear side of the vehicle seat 200.

[0153] Figure 6 shows a schematic diagram of the connecting portion 1220 according to another embodiment. According to this embodiment, the single positioning member 1221a in Figures 1 to 5 is replaced by two positioning members 1221b respectively provided on the left and right sides of the connecting rod 122. The two positioning members 1221b extend downward from the connecting rod 122 toward the main body 1210. Each positioning member 1221b includes a rod portion 1221b-l connected upward to the connecting rod 122 and a head portion 1221b-2 spaced apart from the connecting rod 122 in the vertical direction. The rod portion 1221b-l and the head portion 1221b-2 are connected to each other. The dimension of the head portion 1221b-2 in the horizontal direction is larger than the dimension of the rod portion 1221b-l in the horizontal direction. A positioning groove 1222 is formed in the vertical direction between the connecting rod 122 and the head portion 1221b-2 on the side away from the connecting rod 122. Specifically, the positioning element 1221b is, for example, a screw. Therefore, its shank 1221b-1 is cylindrical, and its head 1221b-2 is flat and circular. The diameter of the head 1221b-2 is larger than the diameter of the shank 1221b-1, and the centerline of the shank 1221b-1 coincides with the centerline of the head 1221b-2. The shank 1221b-1 is screwed upwards into the connecting rod 122 and fixed, so that the flat head 1221b-2 is spaced upwards from the connecting rod 122, forming a positioning groove 1222 between the flat head 1221b-2 and the connecting rod 122. The positioning groove 1222 is specifically located between the connecting rod 122 and the side of the flat head 1221b-2 away from the middle of the connecting rod 122. In other embodiments, the two positioning elements 1221b may also be integrally formed with the connecting rod 122.

[0154] As shown in Figure 6, the backrest portion 1200 is also provided with a restraint strap 1223 located on the outside of the main body portion 1210. The restraint strap 1223 is connected to the main body portion 1210 at both ends in the left-right direction, and the restraint strap 1223 is located on the side of the connecting portion 1220 away from the seat portion 1100 in the front-back direction and is lower than the top of the connecting portion 1220. In this embodiment, the restraint strap 1223 is tautly provided on the outside of the connecting portion 1220.

[0155] As shown in Figure 6, the backrest portion 1200 is also provided with a connecting strap 1224 located on the outside of the main body portion 1210. The connecting strap 1224 is located on the side of the connecting portion 1220 in the front-back direction near the seat portion 1100 and below the top of the connecting portion 1220. One end of the connecting strap 1224 is connected to the main body portion 1210, and the other end of the connecting strap 1224 is provided with a storage bag 1226. The storage bag 1226 is used to store the strap assembly 2000 when it is not in use. As shown in Figure 7, the connecting strap 1224 is connected to the restraint strap 1223 to surround the connecting portion 1220 in the front-back direction. Specifically, the connecting strap 1224 can extend to the top of the connecting portion 1220 and then extend to the side of the restraint strap 1223 near the connecting portion 1220, so that the connecting strap 1224 and the restraint strap 1223 are connected. The components partially overlap and connect with each other in the front-to-back direction, so that the containment bag 1226 is located below the restraint strap 1223 and the opening of the containment bag 1226 is exposed to contain the strap assembly 2000, and the containment bag 1226 can be effectively prevented from moving. Although the connecting strap 1224 and the restraining strap 1223 surround the connecting portion 1220 in the front-back direction, they do not cover the part where the connecting portion 1220 connects to the tie body 2100. Furthermore, the portion of the connecting strap 1224 surrounding the connecting portion 1220 is approximately located between the two positioning members 1221b. In the forward or backward use state, this further prevents both ends of the tie body 2100 from moving toward the middle of the connecting portion 1220. When it is necessary to switch from the forward use state to the backward use state, or vice versa, the connecting strap 1224 and the restraining strap 1223 need to be separated to allow one end of the tie body 2100 to slide along the connecting portion 1220.

[0156] In this embodiment, the connecting strap 1224 and the binding strap 1223 are connected by a buckle 1225. The buckle 1225 includes a male buckle and a female buckle that can be fastened to each other. One of the male buckle and the female buckle is located on one of the connecting strap 1224 and the binding strap 1223, and the other of the male buckle and the female buckle is located on the other of the connecting strap 1224 and the binding strap 1223. In other embodiments, the buckle 1225 may also be replaced by Velcro or a zipper composed of a hook side and a loop side, etc., which is not limited here.

[0157] In this embodiment, after the connecting strap 1224 is connected to the restraint strap 1223, the storage bag 1226 is provided at one end near the connecting portion 1220 in the left-right direction, so that when both ends of the strap body 2100 move to the same side in the left-right direction of the connecting portion 1220, they can be stored in the storage bag 1226.

[0158] Figures 10 to 15 illustrate a child safety seat 100 according to another embodiment. For simplicity, only the differences from the embodiments of Figures 1 to 5 are described.

[0159] As shown in Figures 10 and 11, the first end 2111 of the first segment 2110 and the second end 2121 of the second segment 2120 of the harness assembly 2000 (not shown in Figure 10) are respectively connected to the left and right sides of the seat portion 1100 of the seat body 1000 of the child safety seat 100, specifically to the two side wings 1230 on the left and right sides of the seat portion 1100. The first end 2111 and the second end 2121 are fixed to the two corresponding fixing parts 1250 on the two side wings 1230 of the seat 1100. The first end 2111 and the second end 2121 can pass through the fixing parts 1250 and be fixed to the inside of the child safety seat 100. The fixing part 1250 is, for example, a perforation. The first end 2111 and the second end 2121 can be provided with a D-ring, bow, or other limiting member. The size of the limiting member is larger than the size of the perforation to prevent the first end 2111 and the second end 2121 from coming out of the fixing part 1250.

[0160] As shown in Figure 14, the backrest 1200 includes a first connector 1227 located on the side of the main body 1210 away from the seat 110 in the front-rear direction, a second connector 1228 located on the left and right sides of the main body 1210, and a third connector 1229 (specifically located on the outer sides of the two side wings 1230 on the left and right sides of the main body 1210). The second connector 1228 and the first end 2111 are located on the same side of the child safety seat 100 in the left-right direction, and the third connector 1229 and the second end 2121 are located on the same side of the child safety seat 100 in the left-right direction. The first connector 1227, the second connector 1228, and the third connector 1229 have the same structure, differing only in their positions.

[0161] As shown in Figure 14, one end of the first connector 1227, the second connector 1228, and the third connector 1229 are fixedly connected to the main body 1210, and the other end of the first connector 1227, the second connector 1228, and the third connector 1229 are detachably connected to the main body 1210. The remaining parts of the first connector 1227, the second connector 1228, and the third connector 1229 are spaced apart from the main body 1210, and the first connector 1227, the second connector 1228, and the third connector 1229 and the main body 1210 form a hollow portion 1260b. The strap body 2100 can enter the space formed by the corresponding first connector 1227, the second connector 1228, the third connector 1229 and the main body 1210 from the detachably connected end of the first connector 1227, the second connector 1228, the third connector 1229 and the main body 1210. The hollow portion 1260b formed by the enclosure allows the strap body 2100 to be connected to the backrest portion 1200. The shapes of the first connector 1227, the second connector 1228, and the third connector 1229 are adapted to the width of the strap body 2100 and can prevent the strap body 2100 from coming off.

[0162] As shown in Figure 14, the other end (specifically the upper end) of the first connector 1227, the second connector 1228, the third connector 1229 and the main body 1210 that can be detached from each other is bent toward the end (specifically the lower end) of the first connector 1227, the second connector 1228, the third connector 1229 and the main body 1210 that are fixedly connected to each other, and is set in a hook shape. The first connector 1227, the second connector 1228, and the third connector 1229 are made of an elastic material. When no force is applied, the other ends of the first connector 1227, the second connector 1228, and the third connector 1229 are tightly attached to the main body 1210. When subjected to external force, the other ends of the first connector 1227, the second connector 1228, and the third connector 1229 will separate from the main body 1210, forming a channel for the strap body 2100 to enter the corresponding hollow part 1260b. After the strap body 2100 enters the corresponding hollow part 1260b, the other ends of the first connector 1227, the second connector 1228, and the third connector 1229 will continue to be tightly attached to the main body 1210, thereby preventing the strap body 2100 from detaching from the hollow part 1260b and thus detaching from the connection with the backing part 1200. In other embodiments, the other ends of the first connector 1227, the second connector 1228, and the third connector 1229 may also be spaced apart from the main body 1210 to form a channel for the strap body 2100 to enter the corresponding hollow part 1260b. Regardless of whether the child safety seat 100 is in a forward-facing or rearward-facing use state, the extension direction of the strap body 2100 and the direction in which the strap body 2100 enters the channel can be staggered. For example, the upper ends of the first connector 1227, the second connector 1228, and the third connector 1229 shown in FIG. 14 are spaced apart from the main body 1210, rather than being tightly attached to the surface of the main body 1210 when no force is applied.

[0163] As shown in Figures 10 and 11, when the child safety seat 100 is installed facing the front of the vehicle, the first segment 2110 and the second segment 2120 are located on the left and right sides of the child safety seat 100, respectively. The first segment 2110 enters the hollow portion 1260b formed by the second connector 1228 and the main body 1210, and the second segment 2120 enters the hollow portion 1260b formed by the third connector 1229 and the main body 1210, thereby preventing the first segment 2110 and the second segment 2120 from dislodging from the corresponding hollow portion 1260b. In this way, the first segment 2110 and the second segment 2120 extend from the seat portion 1100 to the backrest portion 1200, and then from the backrest portion 1200 to the vehicle's anchoring point. After the anchoring portion 2200 of the harness assembly 2000 is connected to the anchoring point on the rear side of the backrest 220 of the vehicle seat 200 via the second connector 1228 and the third connector 1229, the first section 2110 and the second section 2120 can provide sufficient force to fix the backrest portion 1200 of the child safety seat 100 against the backrest 220 to prevent it from detaching from the backrest 220. In this embodiment, the two fixing parts 1250 connected to the first part 2110 and the second part 2120 are symmetrically arranged relative to the center line 1 of the child safety seat 100 (which coincides with the center line I of the backrest 1200). The second connector 1228 and the third connector 1229 connected to the first part 2110 and the second part 2120 are also symmetrically arranged relative to the center line I of the child safety seat 100 (which coincides with the center line I of the backrest 1200). The first connector 1227 is disposed on the center line I of the backrest 1200.

[0164] According to Figures 10 and 11, the first segment 2110 extends rearward from the seat portion 1100 on one side of the child safety seat 100 in the left-right direction to between the second connector 1228 and the main body portion 1210, and then extends rearward from between the second connector 1228 and the main body portion 1210 to the vehicle's anchoring point. The second segment 2120 extends rearward from the seat portion 1100 on the other side of the child safety seat 100 in the left-right direction to between the third connector 1229 and the main body portion 1210, and then extends rearward from between the third connector 1229 and the main body portion 1210 to the vehicle's anchoring point.

[0165] According to Figures 12 and 13, when the child safety seat 100 is in the rear-facing position, the first segment 2110 of the strap assembly 2000 is located on one side of the child safety seat 100 in the left-right direction (left side L in Figure 12), and extends forward from the seat 1100 to the backrest 1200, and then extends backward from the backrest 1200 to the anchoring part 2200 connected to the anchoring point of the vehicle seat 200. The second segment 2120 of the strap assembly 2000 is located on the other side of the child safety seat 100 in the left-right direction (right side R in Figure 12), and extends backward from the seat 1100 to the anchoring part 2200 connected to the anchoring point of the vehicle. It can be seen that the strap assembly 200 only extends backward from the backrest 1200 to the anchoring point of the vehicle on one side of the child safety seat 100 in the left-right direction.

[0166] As shown in Figures 12 and 13, specifically, in the rearward use state, the first connector 1227 is located on the front side of the main body 1210. The first end 2111 of the first segment 2110 extends forward from the corresponding fixing part 1250 to the space between the second connector 1228 and the main body 1210 (that is, the first segment 2110 passes through the hollow part 1260b formed by the second connector 1228 and the main body 1210), then extends forward to the front side of the first connector 1227, then extends backward to the space between the first connector 1227 and the main body 1210 (that is, the first segment 2110 passes through the hollow part 1260b formed by the first connector 1227 and the main body 1210), then extends backward to the space between the second connector 1228 and the main body 1210, and finally extends to the anchoring part 2200. The anchoring portion 2200 is then connected to the vehicle's anchoring point. This provides fixation for the backrest 1200 of the child safety seat 100, preventing it from tilting forward. The second segment 2120 extends directly rearward from the corresponding fixing portion 1250 to the anchoring portion 2200. When the child safety seat 100 is installed on the vehicle seat 200 in this state, the first segment 2100 is positioned away from the door, while the second segment 2120 is positioned close to the door, without obstructing the caregiver from carrying the child in or out. In another embodiment, in the rear-facing use state, the first end 2111 of the first segment 2110 can extend directly forward from the corresponding fixing portion 1250 to the front of the first connector 1227, then rearward between the first connector 1227 and the main body 1210, and finally to the anchoring portion 2200, which is then connected to the vehicle's anchoring point. Alternatively, the first end 2111 of the first segment 2110 extends directly from the corresponding fixing part 1250 to the front side of the first connector 1227, then extends rearward to between the first connector 1227 and the main body 1210, then extends rearward to between the second connector 1228 and the main body 1210, and finally extends to the anchoring part 2200, which is then connected to the vehicle's anchoring point.

[0167] As shown in Figure 12, when the child safety seat 100 is in the rear-facing use position, compared with the forward-facing use position in Figure 10, the second segment 2120 is disengaged from the second connector 1228.

[0168] As shown in Figure 15, the first connector 1227 is cut open (from the center line of the backrest portion 1200). It can be seen that the first connector 1227 has a U-shaped bend at its upper end to prevent the strap assembly 2000 from detaching. The lower end of the first connector 1227 extends obliquely into the backrest portion 1200 and is fixed to a reinforcing portion 1240 that is fixedly connected to the main body portion 1210. According to this embodiment, the reinforcing portion 1240 extends perpendicular to the direction shown in the figure, which advantageously ensures the connection strength of the first connector 1227.

[0169] In the rear-facing use mode, the child safety seat disclosed herein has a harness assembly 2000 extending rearward from the backrest 1200 to the vehicle's anchoring point only on one side of the child safety seat 100 in the left-right direction. The other side of the child safety seat 100 does not have a harness assembly 2000 extending rearward from the backrest 1200 to the vehicle's anchoring point. This ensures that the caregiver's passage in or out of the child is unobstructed on this side. Typically, this side is located near the vehicle door. Therefore, when a child enters or exits the child safety seat 100 and the vehicle, it is not necessary to remove the harness assembly 2000. This allows the caregiver to directly enter or exit the child safety seat 100 and the vehicle from this side, making it more convenient to use.

[0170] Figures 16 to 21 show a child safety seat 100o according to yet another embodiment. For simplicity, only the differences from the embodiments of Figures 10 to 15 are described.

[0171] As shown in Figure 16, the upper part of the backrest 1200 is provided with an upper fixing part 1270, and the seat 1100 is provided with a lower fixing part 1280, which are used to connect to the end of the strap body 2100.

[0172] The upper fixing part 1270 may be provided in the middle or side of the upper part of the backrest part 1200. In one embodiment, the upper fixing part 1270 is provided on the side of the upper part of the backrest part 1200 away from the door.

[0173] In an embodiment where two upper fixing portions 1270 are provided, the two upper fixing portions 1270 can be symmetrically located on the two side wings 1230 on the left and right sides of the backrest portion 1200, as shown in Figures 16 and 17. It can be seen that the upper fixing portion 1270 on the right side of the backrest portion 1200 and the upper fixing portion 1270 on the left side of the backrest portion 1200 – the lower fixing portion 1280 – can be provided on the side of the seat portion 1100. In one embodiment, the lower fixing portion 1280 is provided on the side of the seat portion 1100 adjacent to the door.

[0174] In an embodiment where two lower fixing parts 1280 are provided, the two lower fixing parts 1280 can be symmetrically located on the two side wings 1230 on the left and right sides of the seat 1100, as shown in Figures 16 and 17. It can be seen that the structure of the lower fixing part 1280 on the right side of the seat 1100 and the lower fixing part 1280 on the left side of the seat 1100 can be the same as or different from the structure of the aforementioned fixing part 1250, for example, it can be a perforation, a fixing ring or a fixing hook.

[0175] In embodiments where the upper fixing portion 1270 or the lower fixing portion 1280 shown in Figure 17 is a perforation, the two ends of the strap body 2100 of the strap assembly 2000 (i.e., the first end 2111 and the second end 2121 shown in Figure 17) can pass through the perforation and be fixed to the side of the child safety seat 100 facing the seating space. The two ends 2111 and 2121 of the strap body 2100 can be provided with retaining members 2700 such as D-rings or bows. If the size of the retaining member 2700 is larger than the size of the perforation, the first end 2111 and the second end 2121 can be prevented from detaching from the perforation. In one embodiment, the limiting member 2700 is configured such that its dimension in one direction is larger than the size of the perforation and its dimension in another direction is smaller than the size of the perforation. This allows the limiting member 2700 to disengage from the perforation in the other direction, thereby detachably connecting the two ends 2111, 2121 of the strap body 2100 to the upper fixing part 1270 and the lower fixing part 1280. This facilitates the caregiver in adjusting the connection of the ends of the strap body 2100 to different upper fixing parts 1270 or lower fixing parts 1280.

[0176] To increase the strength of at least one of the upper fixing part 1270 and the lower fixing part 1280, as shown in FIG17, the upper fixing part 1270 and / or the lower fixing part 1280 are provided with a reinforcing member 1500, which is fixed to the child safety seat 100. For example, the reinforcing member 1500 may be made of a relatively hard material such as plastic or metal, and may be in a suitable shape such as sheet or block, and may be fixed to the interior of the child safety seat 100 by means of screwing or welding.

[0177] It should be understood that the child safety seat 100 according to this disclosure may not have a lower fixing part 1280, as shown in Figure 20, which will be described later.

[0178] In addition, the upper fixing part 1270 and the lower fixing part 1280 can be located on different sides of the child safety seat 100, or they can be located on the same side of the child safety seat 100.

[0179] In other embodiments where the upper fixing part 1270 or the lower fixing part 1280 uses a fixing ring or a fixing hook, the two ends 211K2121 of the strap body 2100 can also be detachably connected to the upper fixing part 1270 and the lower fixing part 1280.

[0180] Figures 17 and 18 show perspective views of the child safety seat 100 according to this embodiment in a forward-facing use state. Two upper fixing portions 1270 are provided on the upper part of the backrest 1200. These two upper fixing portions 1270 can be arranged symmetrically or asymmetrically. The first end 2111 (see Figure 18) and the second end 2121 (see Figure 17) of the strap body 210 are respectively connected to the two upper fixing portions 1270. The strap assembly 2000 may include an anchoring portion 2200 located between the first end 2111 and the second end 2121 for connection to an anchoring point in the vehicle, and an adjusting member 2300 for adjusting the length. The structure of the anchoring portion 2200 and the adjusting member 2300 may be the same as in the aforementioned embodiment.

[0181] As shown in Figures 17 and 18, the harness assembly 2000 extends rearward from the two upper fixing portions 1270 at the upper part of the backrest portion 1200 and is connected to the vehicle's anchoring point via the anchoring portion 2200, thereby securing the child safety seat 100 to the vehicle seat in a forward-facing use position.

[0182] Figures 19A and 19B show perspective views of a child safety seat in a rear-facing use configuration according to yet another embodiment.

[0183] In the embodiments shown in Figures 19A and 19B, the two ends of the strap body 2100 are respectively connected to the upper fixing portion 1270 and the lower fixing portion 1280 on different sides of the child safety seat 100 in the left-right direction. Specifically, the first end 2111 of the strap body 2100 is connected to the lower fixing portion 1280 on one side of the child safety seat 100 in the left-right direction, so that the portion of the strap body 2100 on that side will not prevent the child caregiver from putting the child into or taking the child safety seat 100 out from that side. The second end 2121 of the strap body 2100 is connected to the upper fixing portion 1270 on the other side of the child safety seat 100 in the left-right direction, so that the other portion of the strap body 2100 on that other side can connect the upper part of the backrest 1200 to the vehicle's anchor point, thereby realizing that the strap assembly 2000 is connected to the backrest 1200 on only one side in the left-right direction of the child safety seat 100. The upper part of the child safety seat is anchored to the vehicle to prevent the child safety seat 100 from tipping forward when the vehicle brakes or a collision occurs.

[0184] In this embodiment, when the lower fixing part 1280 connected to the end of the strap body 2100 is located on the side of the child safety seat 100 near the door, and the upper fixing part 1270 connected to the end of the strap body 2100 is located on the other side of the child safety seat 100 away from the door, it will be much more convenient for the child caregiver to carry the child into or out of the child safety seat 100 from one side of the door. Therefore, when the two ends 2111 and 2121 of the strap body 2100 are detachably connected to the upper fixing part 1270 and the lower fixing part 1280, the child caregiver can adjust the connection of the end of the strap body 2100 to different upper fixing parts 1270 or lower fixing parts 1280 according to the actual situation.

[0185] Figure 20 shows a perspective view of another embodiment of a child safety seat in a rear-facing use configuration. In the embodiment shown in Figure 20, one end 2121 of the strap body 2100 is connected to an upper fixing portion 1270 located on one side of the child safety seat 100 in the left-right direction, and an anchoring portion 2200 is provided at the other end. This allows the strap body 2100 to connect the upper part of the backrest 1200 to the vehicle's anchoring point on that side of the child safety seat 100 in the left-right direction. Similarly, the strap assembly 2000 can be connected to the upper part of the backrest 1200 to the vehicle's anchoring point on only one side of the child safety seat 100 in the left-right direction. Meanwhile, since the other side of the child safety seat 100 in the left-right direction does not have a strap body 2100, the child caregiver can easily carry the child into or out of the child safety seat 100 from that other side.

[0186] In this embodiment, the lower fixing part 1280 may not be provided. As a variation of the above embodiment, the strap body 2100 may have the anchoring part 2200 disposed between the two ends 2111 and 2121. When the child safety seat 100 is in the rear-facing use state, both ends 2111 and 2121 are connected to the same upper fixing part 1270 of the child safety seat 100. Figure 21 shows a perspective view of another embodiment of the child safety seat in the rear-facing use state. In the embodiment shown in Figure 21, the child safety seat 100 has an upper fixing part 1270 and a lower fixing part 1280 on the same side in the left-right direction, as well as a sliding mechanism 1400 connecting the two. The sliding mechanism 1400 is configured such that the end of the strap body 2100 (e.g., the first end 2111) can slide from one of the upper fixing part 1270 and the lower fixing part 1280 to the other and be positioned by means of the sliding mechanism 1400. In this way, when the child safety seat 100 is switched between forward and rearward use, the end of the strap body 2100 (e.g., the first end 2111) does not need to be removed. It can be directly slid to the corresponding upper fixing part 1270 or lower fixing part 1280 and positioned, making it more convenient to use.

[0187] The sliding mechanism 1400 can be provided on the outer surface of one or both sides of the child safety seat 100 in the left-right direction (e.g., on the outer surface of the side wing 1230). Correspondingly, the ends 2111 and 2121 of the harness body 2100 can be provided with sliding members that can slide on the sliding groove or slide rail.

[0188] In a known child safety seat with a top tether, to ensure the connection strength between the top tether and the child safety seat, a reinforcing tube extending along the longitudinal direction (4 degrees) of the backrest shell is provided inside the child safety seat, and the top tether is fixedly connected to the reinforcing tube structure. However, this reinforcement increases product cost and weight, and complicates the structure.

[0189] Figures 22 to 28 illustrate a first embodiment of the present disclosure, wherein: Figure 22 shows a front perspective view of the child safety seat H1 and details of part A; Figure 23 shows a rear perspective view of the child safety seat H1; Figure 24 shows a rear front view of the child safety seat H1; Figures 25A and 25B show cross-sectional views of the child safety seat H1 according to Figure 22 along section line II; Figure 26 shows details of part A in Figure 25; and Figures 27 and 28 show perspective views of the reinforcement H150.

[0190] Referring to Figure 22, the child safety seat H1 includes a seat body H100 for a child to sit on, a harness assembly H200 connecting the seat body H100 to the vehicle, and a base H300 located below the seat body H100. The base H300 is placed on a cloth vehicle seat (not shown), supports the seat body H100, and can be fixed relative to the vehicle seat. The seat body H100 includes a seat portion H110 that contacts the lower body of the child, a backrest portion H120 that contacts the upper body of the child, and a headrest portion H140 that contacts the head of the child. The backrest portion H120 includes a backrest body H121 for supporting the child's back and side wings H130 for protecting the child's sides. The backrest portion H120 has a shell made of a high-strength engineering plastic such as polypropylene (PP) or ABS (Acrylonitrile Butadiene Styrene), and the shell has strip-shaped perforations H123 on both sides. The back support body H121 and the side wings H130 can be formed directly from the shell or covered by the shell.

[0191] The tether assembly H200 is located on the upper part of the seat body H100 and is used to connect the seat body H100 to the vehicle's anchor points (not shown). The anchor points are generally located on the rear side of the vehicle seat. The tether assembly H200 connects the seat body H100 to the vehicle's anchor points, thereby preventing the seat body H100 from tipping forward during vehicle braking or a collision, thus avoiding danger to the child sitting in the seat body H100.

[0192] The lacing assembly H200 includes a lacing body H210 and an anchoring portion H220, which is used to connect to an anchoring point on a vehicle. According to a specific embodiment, the anchoring portion H220 is, for example, a hook used to hook onto the vehicle's anchoring point. The hook is slidably connected to the lacing body H210, which is a long strip of material with a flat cross-section. The lacing body H210 can be formed from a single piece of fabric or composed of multiple pieces of fabric. Optionally, the lacing assembly H200 also includes an adjustment member H230 disposed on the lacing body H210. The adjustment member H230 is used to adjust the length of the lacing body H210 and has an indicator H231 (such as a red-green indicator) capable of visually sensing the tightness of the lacing body H210, located on one side of the adjustment member H230. When the child safety seat H1 is in the forward-facing position, the harness body H210 extends rearwards from the child safety seat H1. At this time, the side of the adjuster H230 with the indicator H231 faces upwards for easy observation by the caregiver. When the side of the adjuster H230 with the indicator H231 faces downwards, it is not conducive to the caregiver's observation. In use, it is desirable for this display side to always face the caregiver so that the caregiver can observe the tightness of the harness body H210. Therefore, the caregiver needs to flip the end of the harness body H210 to adjust the orientation of the adjuster H230, which can cause winding on the harness body H210. The adjuster H230 can also be configured in other forms, and this disclosure is not limited thereto. According to this disclosure, the harness body H210 includes a first segment H211 and a second segment H212. (First segment 19)

[0193] Correction page (Details 91): The end of section H211 and the second section H212 furthest from the seat body H100 is the first end H213. The free ends of the first section H211 and the second section H212 form the second end H214 of the strap body H210, and the second end H214 is releasably connected to the seat body H100.

[0194] According to this disclosure, the first end H214 extends from the outer side of the seat body H100 facing the vehicle and passes through the seat body H100, connecting to the inner side of the entire seat body H100 via the connector H240 of the strap assembly H200. For example, the second end H214 can pass through the seat body H100 through the elongated perforations H121 on both sides of the backrest H120 as shown in Figures 23 and 24, thereby guiding the strap body H210 from the side of the seat. This results in a wider lateral span between the first end H214 of the first segment H211 and the second end H214 (obscured and not shown) of the second segment H212, allowing the backrest H120 to fit more stably against the vehicle backrest. Furthermore, since the perforations H121 extend substantially along the height direction of the seat body H100, the webbing of the strap body H210 can extend perpendicularly to the vehicle seat towards the vehicle seat, preventing the webbing from folding during use. In other words, the H210 body can always be connected between the vehicle seat and the child safety seat H1 in an unfolded state, thus achieving better tension.

[0195] According to this disclosure, the child safety seat H1 has a forward-facing use mode (see Figure 25A) and a rear-facing use mode (see Figure 25B). When the child safety seat H1 is installed in the vehicle seat and is in the forward-facing use mode, after the child sits in the seat body H100, facing the front of the vehicle, the opening of the child safety seat H1 faces the front of the vehicle, and the backrest H120 abuts against the back of the vehicle seat. At this time, the harness assembly H200 is located behind the opening of the child safety seat H1 (hereinafter referred to as the forward-facing installation position) so that the anchoring part H220 engages with the anchoring point located at the rear of the vehicle seat. When the child safety seat H1 is installed in the vehicle seat and in rear-facing mode, the child sits in the seat body H100 facing the rear of the vehicle (not shown in the figure), with the opening of the child safety seat H1 facing the vehicle's parking direction and the backrest H120 away from the vehicle seat back. At this time, the harness assembly H200 is located behind the opening of the child safety seat H1 (hereinafter referred to as the rear-facing installation position) so that the anchoring part H220 engages with the anchoring point located behind the vehicle seat. Since the cross-section of the harness body H210 is flat, when the harness assembly H200 moves from the rear-facing installation position to the front-facing installation position, the harness body H210 will flip inside out, that is, the inner side of the harness body H210 flips to the outer side. In the child safety seats known to the inventor, one end of the top harness is fixedly connected to a reinforcing tube, and when the anchoring part H220 engages with the anchoring point, the anchoring part H222... The tie wood H210 between the tie and the connector will fold, causing wear to the tie wood H210. Referring to the enlarged view in Figure 22, the connector H240 and the reinforcing part H150 are separate parts, and the connector H240 can move freely relative to the reinforcing part H150. When the tie assembly H200 moves from the rear mounting position to the front mounting position, the second end H214 of the tie body H210 can drive the connector H240 to rotate, thus preventing the tie body H210 from forming a fold due to rotation.

[0196] Figures 22 to 25A illustrate the forward-facing use mode of the child safety seat H1. In this state, the strap body H210 is in the forward-facing mounting position, meaning the strap body H210 of the strap assembly H200 is away from the front of the child safety seat H1 and extends rearward to the vehicle seat anchor point. In the rearward-facing use mode shown in Figure 25B, the strap body H210 is in the rearward-facing mounting position, meaning the strap body H210 extends in the opposite direction to Figures 22 to 24 and extends from the front of the child safety seat H1 to the vehicle seat anchor point.

[0197] According to this embodiment, the child safety seat H1 further includes a reinforcing part H150, which is disposed on the seat body 20.

[0198] Correction page (Detail 91) H100 and connector H240 are used to strengthen the connection between the strap body H210 and the seat body H100. Refer also to Figures 22, 25A, 26, 27, and 28 to describe the reinforcing part H150. Figure 26 shows a detail of part A in Figure 25A. The backrest H120 of the seat body H100 has a main body H121 for a child to lean against and a connecting part H122 integrally formed with the main body H121. The connecting part H122 is used to connect with the side wing H126. The reinforcing part H150 is provided at the connecting part H122, and a perforation H121 is provided at the connecting part H122 for the first segment H211 of the strap body H210 to pass through. In addition, the seat body H100 also includes a crossbar H160, which is disposed on the backrest portion H120 and extends along the width direction of the seat body H100. The crossbar H160 can strengthen the backrest portion H120 and can also serve as a shoulder strap tube H160 for supporting and reversing the shoulder strap H162 of the child safety seat H1. The crossbar H160 is fixed to the backrest portion H120 by screws H161.

[0199] The reinforcing part H150 has an abutment part H153 and a fixing part H154. The abutment part H153 is perpendicular to the main body H121 of the backing part H120 and is set as a plane for abutting with the connector H240 of the tie wood body H210. There are two fixing parts H154. In Figure 26, the fixing part H154 above the fabric and the fixing part H154 on the lower left extend vertically from both sides of the abutment part H153 in opposite directions. The two fixing parts H154 are parallel to each other and each has a connecting hole H157. To secure the reinforcing part H150 to the backrest part H120, screws can be passed through the connecting hole H157 and screwed into the fixing hole H124 provided in the backrest part H120. After the reinforcing part H150 is secured to the backrest part H120, the side wing H126 is attached to the attachment part H122 of the backrest part H120, thereby covering the fixing part H154 in the lower left corner of Figures 22 and 26, so as to prevent the screw from accidentally loosening and causing the reinforcing part H150 to detach from the backrest part H120.

[0200] The reinforcing part H150 also has a guide part H152 protruding from the abutment part H153. The guide part H152 extends from the surface of the abutment part H153 to the through hole H123 in the housing of the seat back part H120 (see Figure 26). A guide hole H151 is formed inside the guide part H152. The opening on one side of the guide hole H151 is aligned with the through hole H121, and the opening on the other side is located on the surface of the abutment part H153 away from the through hole H121. The strap body H210 passes through the guide hole H151 and exits the housing of the back part H120 through the through hole H121. This can better guide the sliding of the strap body H210 relative to the seat body H100 and prevent the strap body H210 from folding or getting stuck. In other embodiments, the guide part H152 may not extend to the through hole H121, and this disclosure is not limited thereto.

[0201] The guide hole H151 has an elongated opening at the surface of the abutment portion H153 (see Figure 27) that extends along the length of the seat body H100 (see Figure 22). The guide hole H151 has a widened portion H158 in the middle. For example, the width of the opening of the guide hole H151 at the surface of the abutment portion H153 gradually increases from both ends to the middle. The width of the widened portion H158 in the middle of the guide hole H151 is greater than the width of its two ends. Therefore, when the strap assembly H200 is in a forward-mounted or rearward-mounted position and is tightened, the narrower ends of the guide hole H151 prevent the strap body H210 from slipping. When the strap assembly H200 switches between the forward-mounted and rearward-mounted positions, the strap body H210 can be rotated at the wider widened portion H158 to avoid winding and folding.

[0202] In this embodiment, two perforations H123 are respectively provided on the left and right sides of the housing of the backrest H120. Therefore, when the strap body H210 is in the rear mounting position, the strap body H210 will not wrap around the housing of the backrest H120 from the back to the side, thus reducing the friction area between them. Furthermore, when the strap body H210 switches between the front mounting position and the rear mounting position, the strap body H210 will not contact the rear and side surfaces of the backrest H120.

[0203] The corner of the correction page (Detail 91) also prevents the strap body H210 from winding and folding. In other embodiments, the bud hole H123 may also be provided on the back of the backing part H120.

[0204] The connector H240 of the strap assembly H200 is set as a flat buckle H240o, as shown in Figure 22. The connector H240 is set as a strip-shaped sheet, which extends substantially along the height direction of the seat body H100 when the strap body H210 is taut. The connector H240 has at least two parallel openings H241. The free end of the second end H214 of the strap body H210 passes sequentially through the at least two parallel openings H241 and overlaps with the remainder of the first end H214 after changing direction at H180 degrees. It can be configured as a fixed connection, such as by stitching, gluing, etc. (see Figure 26). The connector H240 may also have three or more parallel openings H24K. The flat side of the connector H240 abuts against the surface of the reinforcement H150 in parallel. The area of ​​the flat side is larger than the opening area of ​​the guide hole H153 at the abutment H153. Thus, when the first end H213 of the strap body H210 is fixed to the vehicle seat, the connector H240 can be engaged with the abutment H153 from the inside of the seat to provide engagement of the second end H214 of the strap body H210. Since the opening of the guide hole H153 is elongated and the connector H240 is set as a flat elongated sheet, during installation, the connector H240 can be first inserted horizontally into the guide hole H153 from the outside of the seat. After passing through the guide hole H153 and extending to the inside of the seat, the connector H240 is reversed so that it is engaged with the abutment part H153 ± (see Figure 26).

[0205] When the child safety seat H1 changes from the forward-facing mode to the rear-facing mode or vice versa as shown in Figures 22 to 24, the harness body H210, for example, changes from extending rearward as shown in Figure 22 to extending forward. In this case, for example, the display side of the adjustment piece H230 of the harness body H210 used to show the tightness of the harness body H210 will be flipped, making it difficult for the caregiver to easily observe the tightness of the harness body H210. If the caregiver wants to see the display side directly, the harness body H210 needs to be flipped H180 degrees in the guide hole H151, and the connector H240 needs to be flipped H180 degrees from the state shown in Figure 22. During the flipping process, the webbing of the harness body H210 will be deformed and squeezed in the guide hole H153 due to its width, and may even be stuck by the guide hole H153.

[0206] According to this disclosure, a gradually widening extension H158 is provided in the guide hole H153 to prevent the fabric from being stuck in the guide hole H153 when flipping the connector H240 and the tie body H210.

[0207] Referring to Figure 26, the reinforcing part H150 also has a protrusion H156 perpendicular to the abutting part H153, used to abut against the main body H121 of the backing part H120.
