Description

Technical Field

[0001] This disclosure relates to a child vehicle, and more particularly to a child safety seat. Background Technology

[0002] Child safety seats provide children with a comfortable and safe sitting or lying space 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.

[0003] In addition, a reinforcement structure is installed between the child safety seat and the top harness (also known as the "top tether") to enhance the connection's strength. Existing reinforcement structures are often complex and inconvenient to use. Summary of the Invention

[0166] 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.

[0167] The directional descriptions such as "F" (front), "B" (rear), "L" (left), "R" (right), "T" (upper), and "D" (lower) 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.

[0168] Figure 1 A perspective view is shown 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.

[0169] like Figure 1 and 3As shown, 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 180° relative to the forward-facing position, allowing the child to sit facing the rear of the vehicle. Figure 3 As shown, specifically the backrest 220 facing the vehicle seat 200.

[0170] like Figure 1 and Figure 2 As shown, 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-rear 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. Figure 3 As shown, 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.

[0171] 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 a forward-facing or rearward-facing use state. The anchor point is generally located on the rear side of the backrest 220 of the vehicle seat 200. By connecting the seat body 1000 to the vehicle's 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, thereby avoiding danger to the child sitting in the seat body 1000.

[0172] like Figure 1 and Figure 2The 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 the upper body from 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, which laterally protect the child's upper body in the left and right directions to avoid the upper body from 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 vertically spaced 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 to the harness assembly 2000 and can also be used as a handle for carrying the child safety seat 100. In other embodiments, the connecting portion 1220 may also be disposed along the front-rear direction on the side of the main body 1210 away from the seat portion 1100, instead of being disposed on the upper side of the main body 1210. The hollow portion 1260a formed between the connecting portion 1220 and the main body 1210 is located on the side of the main body 1210 away from the seat portion 1100 in the front-rear direction. In other embodiments, the connecting portion 1220 may also be continuously connected to the main body 1210 along the left-right direction, instead of only its left and right ends being connected to the main body 1210. The connecting portion 1220 itself forms the aforementioned hollow portion 1260a for connection with the strap assembly 2000.

[0173] like Figure 1 and Figure 2 As shown, 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 the lower body from being impacted from the left and right. 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 the lower body from being impacted from the left and right.

[0174] like Figure 1 and Figure 2As shown, 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 for hooking 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 defines a first segment 2110 and a second segment 2120 of the lacing body 2100, meaning the first segment 2110 and the second segment 2120 are located on both sides of the anchoring portion 2200. The lengths of the first segment 2110 and the second segment 2120 can be adjusted by moving the anchoring part 2200. According to this disclosure, the strap assembly 2000 may be formed from a single piece of fabric or composed of multiple pieces of fabric.

[0175] like Figure 2 As shown, 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 constructed as collars 2111 and 2121, which 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 together by the 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 located in the hollow portion 1260. The collars 2111 and 2121 formed by the first end 2111 and the second end 2121 are not tightly attached to the connecting part 1220, but are left with a gap. The gap is sufficient to allow the first end 2111 and the second end 2121 to slide along the connecting part 1220 when the strap body 2100 is in a relaxed state.

[0176] like Figure 2 , Figure 3 , Figure 8 and Figure 9As shown, the tie assembly 2000 also includes an adjustment member 2300 through which the tie body 2100 passes. The adjustment member 2300 is used to adjust the overall length of the first section 2110 and the second section 2120. Specifically, with the adjustment member 2300 as the boundary, the tie body 2100 can be further divided into a first tie 2500 and a second tie 2600. The first tie 2500 is a portion of the second section 2120, and the second tie 2600 includes a portion of the second section 2120 and the entire first section 2110. One end of the first strap 2500 (i.e., the second end 2121) is connected to the connecting portion 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 portion 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 can be adjusted, that is, the overall length of the first segment 2110 and the second segment 2120. In this embodiment, the adjusting member 2300 is provided on the second segment 2120. In other embodiments, the adjusting member 2300 can also be provided on the first segment 2110. In other embodiments, the adjusting member 2300 may not be provided.

[0177] like Figure 8 and Figure 9 As shown, the adjusting member 2300 has two connecting shafts 2310, which are 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 to form a collar 2520 via a joining portion 2510, such as a stitch. One end of the first strap 2500 is the second end portion 2121, thus forming collars 2121 and 2520 at both ends. 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 portion 2111, forming a collar 2111.

[0178] like Figure 1As shown, 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).

[0179] like Figure 2 As shown, 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 anchor 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 the two 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.

[0180] like Figure 1 and Figure 2 As shown, when the child safety seat 100 is in the forward-facing use state, 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 and right direction. At this time, the first section 2110 and the second section 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 part 1200 to the anchoring part 2200 connected to the vehicle's anchoring point.

[0181] like Figure 3 and Figure 4 As shown, when the child safety seat 100 is in the rear-facing position, the harness assembly 2000 is only on one side of the child safety seat 100 in the left-right direction (e.g., Figure 3 and Figure 4The left side (L) extends from the backrest 1200 to the vehicle's anchor point. Specifically, the entire strap assembly 2000 is located on one side of the child safety seat 100 in the left-right direction and extends from the connecting portion 1220 of the backrest 1200 to the vehicle's anchor point. Both ends of the strap body 2100 are connected to the same side of the backrest 1200 in the left-right direction. Specifically, both ends of the strap body 2100 are located on the same side of the positioning groove 1222 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 harness assembly 2000 is positioned away from the vehicle door in the left and right directions, while the side of the child safety seat 100 without the harness assembly 2000 in the left and right directions is positioned close to the vehicle door, so as to facilitate the child caregiver to put the child into or take the child safety seat 100 out from that side.

[0182] According to this disclosure, whether in the forward use state or the 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 can be spaced apart from the positioning groove 1222 in the left and right directions. When the anchoring part 2200 is connected to the vehicle's anchoring point, the strap body 2100 is tightened. When the first end 2111 and the second end 2121 move in the left-right direction toward the center of the connecting part 1220, the bottom of the positioning groove 1222 can block the first end 2111 and the second end 2121, thereby limiting the first end 2111 and the second end 2121 to the side of the corresponding positioning groove 1222 away from the center of the connecting part 1220, so as to prevent 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 the forward or backward use state.

[0183] 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 loose state. Then, the first end 2111 of the first segment 2110 or the second end 2121 of the second segment 2120, which is close to the vehicle door, slides from the side of 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 side of the 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 member 2300.

[0184] like Figure 3 and Figure 4 As shown, with Figure 1 , 2 Compared to the forward use state, the first end 2111 of the first segment 2110 moves from the side of the positioning groove 1222 on the left-right side of the connecting portion 1220 away from the middle of the connecting portion 1220 to the side of the positioning groove 1222 on the other side of the left-right direction away from the middle of the connecting portion 1220, so that it is located in the same positioning groove 1222 away from the middle of the connecting portion 1220 as the second end 2121 of the second segment 2120.

[0185] like Figure 2 As shown, 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 can also be integrally formed with the connecting part 1220, i.e., a one-piece structure.

[0186] Figure 5A perspective view shows a child safety seat 100 installed rearward according to one embodiment. Figure 4 Differently, Figure 5 The rear cover of the seat body 1000 has been removed, allowing a view of the interior.

[0187] 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 the child safety seat 100 from deforming.

[0188] 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 also be one or more, or in other forms, and this disclosure is not limited thereto.

[0189] Figure 5 The anchoring part 2200 can also be seen, which 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.

[0190] Figure 6 A schematic diagram of a connection portion 1220 according to another embodiment is shown. According to this embodiment, [the connection portion 1220 is...]. Figures 1 to 5The single positioning element 1221a is replaced by two positioning elements 1221b respectively disposed on the left and right sides of the connecting rod 122. The two positioning elements 1221b extend downward from the connecting rod 122 toward the main body 1210. The positioning element 1221b includes a rod portion 1221b-1 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-1 and the head portion 1221b-2 are connected to each other. The size of the head portion 1221b-2 in the horizontal direction is larger than the size of the rod portion 1221b-1 in the horizontal direction. The 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 middle of the connecting rod 122. Specifically, the positioning element 1221b is, for example, a screw, so 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 upward into the connecting rod 122 and fixed, so that the flat head 1221b-2 is spaced upward 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.

[0191] like Figure 6 As shown, 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.

[0192] like Figure 6 As shown, the backrest 1200 is also provided with a connecting strap 1224 located on the outside of the main body 1210. The connecting strap 1224 is located on the side of the connecting part 1220 in the front-back direction near the seat 1100 and below the top of the connecting part 1220. One end of the connecting strap 1224 is connected to the main body 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.

[0193] like Figure 7As shown, the connecting strap 1224 and the restraint strap 1223 are connected to each other 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 to the side of the restraint strap 1223 near the connecting portion 1220, so that the connecting strap 1224 and the restraint strap 1223 partially overlap and connect to each other in the front-back direction, and the storage bag 1226 is located below the restraint strap 1223, and the opening of the storage bag 1226 is exposed to accommodate the strap assembly 2000, and the storage 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.

[0194] In this embodiment, the connecting strap 1224 and the restraint 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 restraint 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 restraint strap 1223. In other embodiments, the buckle 1225 can also be replaced by Velcro or a zipper composed of a hook side and a loop side, etc., which is not limited here.

[0195] In this embodiment, after the connecting strap 1224 is connected to the restraint strap 1223, the storage bag 1226 is provided near one end of 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.

[0196] Figures 10 to 15 A child safety seat 100 according to another embodiment is shown. For simplicity, only the following description is provided. Figures 1 to 5 The differences between the embodiments.

[0197] like Figure 10 and Figure 11 As shown, the first end 2111 of the first segment 2110 of the tether assembly 2000 and the second end 2121 of the second segment 2120 ( Figure 10(Not shown) are respectively connected to the left and right sides 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 body 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 body 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.

[0198] like Figure 14 As shown, 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.

[0199] like Figure 14 As shown, one end of the first connector 1227, the second connector 1228, and the third connector 1229 is 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 is detachably connected to the main body 1210. The remaining portions 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 are... The connector 1229 and the main body 1210 form a hollow portion 1260b. The strap body 2100 can enter the hollow portion 1260b formed by the corresponding first connector 1227, second connector 1228, third connector 1229 and the main body 1210 from the end that is detachably connected to the first connector 1227, second connector 1228, third connector 1229 and the main body 1210, so that the strap body 2100 can be connected to the backing portion 1200. The shapes of the first connector 1227, second connector 1228, and third connector 1229 are adapted to the width of the strap body 2100 and can prevent the strap body 2100 from detaching.

[0200] like Figure 14As shown, the other end (specifically the upper end) of the first connector 1227, the second connector 1228, and the third connector 1229 that can be detachably connected to the main body 1210 is bent toward the end (specifically the lower end) of the first connector 1227, the second connector 1228, and the third connector 1229 that is fixedly connected to the main body 1210, and is arranged 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 tie body 2100 to enter the corresponding hollow part 1260b. After the tie 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 tie body 2100 from detaching from the hollow part 1260b and thus 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 harness body 2100 to enter the corresponding hollow portion 1260b. Regardless of whether the child safety seat 100 is in a forward-facing or rear-facing position, the extension direction of the harness body 2100 and the direction in which the harness body 2100 enters the channel can be staggered. For example, [the following text is incomplete and requires further context]. Figure 14 The upper ends of the first connector 1227, the second connector 1228, and the third connector 1229 shown are spaced apart from the main body 1210, rather than being in close contact with the surface of the main body 1210 when no force is applied.

[0201] like Figure 10 and Figure 11As shown, when the child safety seat 100 is installed facing the front of the vehicle, the first section 2110 and the second section 2120 are respectively located on the left and right sides of the child safety seat 100. The first section 2110 enters the hollow portion 1260b formed by the second connector 1228 and the main body 1210, and the second section 2120 enters the hollow portion 1260b formed by the third connector 1229 and the main body 1210, so as to restrict the first section 2110 and the second section 2120 from coming out of the corresponding hollow portion 1260b. In this way, the first section 2110 and the second section 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 segment 2110 and the second segment 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 portions 1250 connected to the first segment 2110 and the second segment 2120 are symmetrically arranged relative to the center line I of the child safety seat 100 (coinciding with the center line I of the backrest portion 1200). The second connector 1228 and the third connector 1229 connected to the first segment 2110 and the second segment 2129 are also symmetrically arranged relative to the center line I of the child safety seat 100 (coinciding with the center line I of the backrest portion 1200). The first connector 1227 is disposed on the center line I of the backrest portion 1200.

[0202] according to Figure 10 , 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.

[0203] according to Figure 12 , 13 When the child safety seat 100 is in the rear-facing position, the first segment 2110 of the harness assembly 2000 is located on one side of the child safety seat 100 in the left-right direction (e.g., Figure 12The left side (L) of the child safety seat 100 extends forward from the seat 1100 to the backrest 1200, and then backward from the backrest 1200 to the anchoring part 2200 connected to the anchoring point of the vehicle seat 200. The second section 2120 of the harness assembly 2000 is located on the other side of the child safety seat 100 in the left-right direction (e.g., the left side L), 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. Figure 12 The right side (R) of the child safety seat 100 extends rearward from the seat 1100 to the anchoring part 2200, which connects to the vehicle's anchoring point. It can be seen that the harness assembly 200 extends 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.

[0204] like Figure 12 and Figure 13 As shown, 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, which is then connected to the vehicle's anchoring point. In this manner, the backrest 1200 of the child safety seat 100 is secured to prevent 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.

[0205] like Figure 12As shown, when the child safety seat 100 is in the rear-facing position, it is in harmony with... Figure 10 Compared to the forward-facing usage state, the second segment 2120 disengages from the second connector 1228.

[0206] like Figure 15 As shown, the image is cut open from the first connector 1227 (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 drawing direction, which advantageously ensures the connection strength of the first connector 1227.

[0207] 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 anchor 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 in the left-right direction does not have a harness assembly 2000 extending rearward from the backrest 1200 to the vehicle's anchor point. This ensures that the child caregiver's passage in or out of the child is unobstructed. This side is usually located near the vehicle door, so the harness assembly 2000 does not need to be removed when the child enters or exits the child safety seat 100 and the vehicle. This makes it easier for the child caregiver to directly enter or exit the child safety seat 100 and the vehicle from this side, making it more convenient to use.

[0208] Figures 16 to 21 A child safety seat 100 according to yet another embodiment is shown. For simplicity, only the following description is provided. Figures 10 to 15 The differences between the embodiments.

[0209] like Figure 16 As shown, 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.

[0210] 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.

[0211] In an embodiment where two upper fixing parts 1270 are provided, the two upper fixing parts 1270 can be symmetrically located on the two side wings 1230 on the left and right sides of the backing part 1200, such as... Figure 16 and Figure 17 As shown, the upper fixing part 1270 on the right side of the backrest 1200 and the upper fixing part 1270 on the left side of the backrest 1200 can be seen respectively.

[0212] The lower fixing part 1280 may be provided on the side of the seat part 1100. In one embodiment, the lower fixing part 1280 is provided on the side of the seat part 1100 adjacent to the door.

[0213] 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 part 1100, such as... Figure 16 and Figure 17 As shown, 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 seen respectively.

[0214] The structure of the upper fixing part 1270 and the lower fixing part 1280 may be the same as or different from the structure of the aforementioned fixing part 1250, for example, it may be a perforation, a fixing ring or a fixing hook.

[0215] exist Figure 17 In the embodiment where the upper fixing part 1270 or the lower fixing part 1280 is perforated, the two ends of the strap body 2100 of the strap assembly 2000 (i.e., Figure 17 The first end 2111 and the second end 2121 shown can be fixed to the side of the child safety seat 100 facing the seating space through the perforation. The two ends 2111 and 2121 of the strap body 2100 can be provided with retaining members 2700 such as D-rings or bows. When 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 retaining member 2700 is configured such that its size in one direction is larger than the size of the perforation, and its size in another direction is smaller than the size of the perforation. This allows the retaining member 2700 to detach from the perforation in the other direction, thereby detaching the two ends 2111 and 2121 of the strap body 2100 from the upper fixing part 1270 and the lower fixing part 1280, facilitating the caregiver's adjustment of the connection between the ends of the strap body 2100 and different upper fixing parts 1270 or lower fixing parts 1280.

[0216] To increase the strength of at least one of the upper fixing part 1270 and the lower fixing part 1280, such as Figure 17 As shown, 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.

[0217] It should be understood that the child safety seat 100 according to this disclosure may not have a lower fixing part 1280, as will be described below. Figure 20The situation is shown below.

[0218] 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.

[0219] 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 2111 and 2121 of the strap body 2100 can also be detachably connected to the upper fixing part 1270 and the lower fixing part 1280.

[0220] Figure 17 and Figure 18 A perspective view showing the child safety seat 100 according to this embodiment in a forward-facing use state.

[0221] The upper part of the backrest 1200 is provided with two upper fixing parts 1270. These two upper fixing parts 1270 can be arranged symmetrically or asymmetrically. The first end 2111 of the strap body 210 (see...) Figure 18 ) and the second end 2121 (see Figure 17 The strap assembly 2000 may include an anchoring part 2200 for connection to an anchoring point on a vehicle, located between a first end 2111 and a second end 2121, and an adjusting member 2300 for adjusting the length. The structure of the anchoring part 2200 and the adjusting member 2300 may be the same as in the aforementioned embodiment.

[0222] like Figure 17 and Figure 18 As shown, the strap 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 fixing the child safety seat 100 to the vehicle seat in a forward-facing use state.

[0223] Figure 19A and Figure 19B A perspective view showing a child safety seat in a rear-facing use position according to yet another embodiment.

[0224] exist Figure 19A and Figure 19BIn the illustrated embodiment, the two ends of the strap body 2100 are respectively connected to an upper fixing portion 1270 and a lower fixing portion 1280 located 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 located 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 from that side. The second end 2121 of the strap body 2100 is connected to the upper fixing part 1270 on the other side in the left-right direction of the child safety seat 100. This allows the other part of the strap body 2100 on the other side to connect the upper part of the backrest 1200 to the vehicle's anchor point. This enables the strap assembly 2000 to connect the upper part of the backrest 1200 to the vehicle's anchor point on only one side in the left-right direction of the child safety seat 100, so as to prevent the child safety seat 100 from overturning forward when the vehicle brakes or a collision occurs.

[0225] 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.

[0226] Figure 20 A perspective view showing another embodiment of a child safety seat in a rear-facing use position.

[0227] exist Figure 20 In the illustrated embodiment, one end 2121 of the strap body 2100 is connected to the upper fixing part 1270 located on one side of the child safety seat 100 in the left-right direction, and the other end is provided with an anchoring part 2200. 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 there is no strap body 2100 on the other side of the child safety seat 100 in the left-right direction, the child caregiver can easily put the child into or take the child safety seat 100 from that other side.

[0228] In this embodiment, the lower fixing part 1280 may not be provided.

[0229] 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.

[0230] Figure 21 A perspective view showing yet another embodiment of a child safety seat in a rear-facing use position.

[0231] exist Figure 21 In the illustrated embodiment, 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 thereby using the sliding mechanism 1400. Thus, 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 disassembled; it can simply slide to the corresponding upper fixing part 1270 or lower fixing part 1280 and be positioned thereby, making it more convenient to use.

[0232] The sliding mechanism 1400 can be provided in a groove or rail 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 strap body 2100 can be provided with sliders that can slide on the groove or rail.

[0233] 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 length (longitudinal direction) of the backrest is provided inside the shell of the child safety seat, and the top tether is fixedly connected to the reinforcing tube structure. However, this reinforcement results in increased product cost and weight, as well as structural complexity.

[0234] Figures 22 to 28 This first embodiment of the present disclosure is shown, wherein, Figure 22 Showing a front perspective view of child safety seat H1 and detail of part A. Figure 23 A 3D view of the rear side of child safety seat H1 is shown. Figure 24 Showing a rear front view of the child safety seat H1, Figure 25A and Figure 25B Showing according to Figure 22A cross-sectional view of the child safety seat H1 along section line II; Figure 26 Showing local A in Figure 25A Details in Figure 27 and Figure 28 A perspective view of the reinforcing section H150 is shown.

[0235] See Figure 22 The child safety seat H1 includes a seat body H100 for a child to sit in, 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 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 elongated perforations H123 on both sides of the shell. The back support body H121 and the side wings H130 can be formed directly from the shell or covered by the shell.

[0236] 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 point (not shown). The anchor point is generally located on the rear side of the vehicle seat. The tether assembly H200 connects the seat body H100 to the vehicle's anchor point, thereby preventing the seat body H100 from tipping forward when the vehicle brakes or a collision occurs, thus avoiding danger to the child sitting in the seat body H100.

[0237] 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 this 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 has an adjusting member H230 disposed on the lacing body H210. The adjusting 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 adjusting 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. The end of the first segment H211 and the second segment H212 furthest from the seat body H100 is the first end H213. The free ends of the first segment H211 and the second segment H212 form the second end H214 of the strap body H210, which is releasably connected to the seat body H100.

[0238] According to this disclosure, the second end H214 extends from the outer side of the seat body H100 facing the vehicle, passes through the seat body H100, and is connected to the inner side of the seat body H100 via the connector H240 of the strap assembly H200. For example, the second end H214 can be... Figure 23 and Figure 24The elongated perforations H121 on both sides of the backrest H120 shown pass through the seat body H100, thereby guiding the strap body H210 from the side of the seat. This results in a wider lateral span between the second end H214 of the first segment H211 and the second end H214 of the second segment H212 (obscured and not shown), allowing the backrest H120 to fit more stably against the vehicle backrest. Furthermore, the perforations H121 extend substantially along the height direction of the seat body H100, allowing the webbing of the strap body H210 to extend perpendicularly towards the vehicle seat, preventing the webbing from folding during use. In other words, the strap body H210 can always be connected between the vehicle seat and the child safety seat H1 in an unfolded state, thus achieving better tension.

[0239] According to this disclosure, the child safety seat H1 has a forward-facing usage mode (see...). Figure 25A ) and backward usage patterns (see Figure 25B When the child safety seat H1 is installed in the vehicle seat and in forward-facing mode, the child sits in the seat body H100 facing forward of the vehicle, with the opening of the child safety seat H1 facing the front of the vehicle. The backrest H120 rests 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 anchor 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 rear of the vehicle. The backrest H120 is away from 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 rear-facing installation position) so that the anchoring part H220 engages with the anchor point located at the rear of the vehicle seat. Because the cross-section of the strap body H210 is flat, when the strap assembly H200 moves from the rear-mounted position to the front-mounted position, the strap body H210 will flip inwards and outwards, meaning the inner side of the strap body H210 will flip to the outer side. In child safety seats known to the inventor, one end of the top tether is fixedly connected to a reinforcing tube. When the anchor part H220 engages with the anchor point, the strap body H210 between the anchor part H220 and the connector will fold, causing wear to the strap body H210. See also Figure 22 The enlarged view shows that 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 strap assembly H200 moves from the rear mounting position to the front mounting position, the second end H214 of the strap body H210 can drive the connector H240 to rotate, so as to prevent the strap body H210 from forming a fold due to rotation.

[0240] Figures 22 to 25A The child safety seat H1 is shown in forward-facing mode. In this state, the strap body H210 is in the forward-facing installation 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 anchor point of the vehicle seat. Figure 25B In the rearward usage mode shown, the lacing body H210 is in the rearward mounting position, that is, the lacing body H210 faces the opposite direction. Figures 22 to 24 It extends in the direction of the child safety seat H1 and extends from the front side of the child safety seat H1 to the anchor point of the vehicle seat.

[0241] According to this embodiment, the child safety seat H1 further includes a reinforcing part H150. The reinforcing part H150 is disposed between the seat body H100 and the connector H240, and is used to strengthen the connection between the strap body H210 and the seat body H100.

[0242] See also Figure 22 , Figure 25A , Figure 26 , Figure 27 and Figure 28 To describe the reinforced section H150. Figure 26 Showing local A in Figure 25A In detail, the backrest portion H120 of the seat body H100 has a main body H121 for a child to lean against and a connecting portion H122 integrally formed with the main body H121. The connecting portion H122 is used to connect with the side wings H126. A reinforcing portion H150 is provided at the connecting portion H122, and a through hole H121 is provided at the connecting portion H122 for the first section H211 of the harness body H210 to pass through. In addition, the seat body H100 also includes a crossbar H160, which is provided at 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.

[0243] 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 against the connector H240 of the strap body H210. Two fixing parts H154 are provided. Figure 26The fixing part H154 at the upper right and the fixing part H154 at the lower left extend vertically in opposite directions from both sides of the abutment part H153. The two fixing parts H154 are parallel to each other and each has a connecting hole H157. In order to fix the reinforcing part H150 to the backing part H120, a screw can be screwed through the connecting hole H157 into the fixing hole H124 provided in the backing part H120. After the reinforcing part H150 is fixed to the backing part H120, the side wing H126 is attached to the attachment part H122 of the backing part H120, thereby covering the area. Figure 22 and Figure 26 The fixing part H154 is located in the lower left corner to prevent the screw from accidentally loosening and coming off, which would cause the reinforcing part H150 to detach from the backing part H120.

[0244] The reinforcing part H150 also has a guide part H152 protruding from the abutment part H153, the guide part H152 extending from the surface of the abutment part H153 to the through hole H123 at the housing of the seat back part H120 (see Figure 26 A guide hole H151 is formed inside the guide portion H152. One opening of the guide hole H151 is aligned with the through hole H121, and the other opening is located on the surface of the abutment portion H153 away from the through hole H121. The strap body H210 passes through the guide hole H151 and exits the housing of the backrest portion H120 through the through hole H121. This better guides the sliding of the strap body H210 relative to the seat body H100, preventing the strap body H210 from folding or getting stuck. In other embodiments, the guide portion H152 may not extend to the through hole H121, and this disclosure is not limited thereto.

[0245] The cross-section of the opening of the guide hole H151 at the surface of the abutment part H153 is set to be elongated (see...). Figure 27 And 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 the forward mounting position or the rear mounting position and is tightened, the ends of the guide hole H151 are narrower, which can prevent the strap body H210 from slipping. When the strap assembly H200 switches between the forward mounting position and the rear mounting position, the strap body H210 can be flipped at the wider widened portion H158 to avoid winding and folding.

[0246] 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-facing 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-facing and rear-facing mounting positions, the strap body H210 will not contact the rear and side corners of the backrest H120, also preventing the strap body H210 from winding or folding. In other embodiments, the perforations H123 may also be provided on the back of the backrest H120.

[0247] The connector H240 of the lacing assembly H200 is a flat buckle H240. For example... Figure 22 As shown, the connector H240 is a long strip of sheet that 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 second end H214 after a 180-degree turn. It can be configured for a fixed connection, such as by stitching or gluing (see [reference]). Figure 26 The connector H240 may also have three or more parallel openings H241. The flat side of the connector H240 abuts against the surface of the reinforcement H150, and 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 engage with the abutment H153 from the inside of the seat to provide engagement for the second end H214 of the strap body H210. Since the opening of the guide hole H153 is elongated and the connector H240 is designed as a flat, elongated sheet, during installation, the connector H240 can be first horizontally inserted into the guide hole H153 from the outside of the seat. After extending through the guide hole H153 to the inside of the seat, the connector H240 can be reversed to engage with the abutment H153 (see [link]). Figure 26 ).

[0248] From the child safety seat H1 Figures 22 to 24 When switching from forward use mode to backward use mode or vice versa, the tether body H210 will, for example, switch from... Figure 22The backward extension is changed to a forward extension. In this case, for example, the display side of the adjustment piece H230 of the strap body H210, which is used to show the tightness of the strap body H210, will be flipped, making it difficult for the caregiver to easily observe the tightness of the strap body H210. If the caregiver wants to see the display side directly, the strap body H210 needs to be flipped H180 degrees in the guide hole H151, and the connector H240 needs to be moved from... Figure 22 The state shown is flipped H180 degrees. During the flipping process, the webbing of the tie body H210 will be deformed and squeezed in the guide hole H153 due to its width, and may even be stuck in the guide hole H153.

[0249] According to this disclosure, a gradually widening extension H158 is provided in the guide hole H153 to prevent the webbing from being stuck in the guide hole H153 when flipping the connector H240 and the tie body H210.

[0250] See Figure 26 The reinforcing part H150 also has a protrusion H156 perpendicular to the abutting part H153, for abutting against the main body H121 of the backing part H120. Simultaneously, the protrusion H156 strengthens the fixing part H154. According to this disclosure, the protrusion H156 is shape-fitted to the crossbar H160, and its specific form can be varied accordingly; this disclosure is not limited to the figures.

[0251] Furthermore, the reinforcing part H150 has multiple ribs H155 on the side opposite to the connector H240. These ribs H155 can engage with the protrusions H155 on the main body H121 of the backing part H120 or the joint H122, thereby providing additional form engagement to prevent misalignment and strengthen the component (see...). Figure 26 , Figure 28 ).

[0252] Figures 29 to 33 This illustrates a second embodiment of the present disclosure. Figure 30 A front perspective view of a child safety seat H1 according to a second embodiment is shown, with details of part B shown. Figure 29 A front perspective view of the child safety seat H1 according to the second embodiment is shown.

To avoid repetition, only the differences from the first embodiment are described.

[0253] According to the second embodiment, reinforcing portions H170 are provided at both ends of the crossbar H160 near the joint H122 of the backing portion H120. The reinforcing portions H170 are flat reinforcing iron sheets, having a fixing portion H171 and an opening H172 that are fixedly connected to the crossbar H160. The shape of the reinforcing portions H170 is approximately rectangular. Figure 30 As shown, the sides of the rectangle may also have notches to avoid components or molded parts on the backrest H120. A fixing part H171 is provided on one side of the reinforcing part H170, for example, at a corner of the rectangle. An opening H172 is provided in the middle of the reinforcing part H170 and is elongated. The fixing part H171 can be a round hole located at one end of the reinforcing part H170. The crossbar H160 is inserted into the round hole and welded together, further increasing the connection strength. According to this disclosure, the reinforcing part H170 extends from the crossbar H160 at a certain angle relative to the height direction of the seat body H100, and the opening H172 is located at the other end of the reinforcing part H170 and extends along the height direction of the seat body H100, thereby allowing the harness body H210 to always be connected between the vehicle seat and the child safety seat H1 in an extended state. Optionally, the middle part of the opening H172 of the reinforcing part H170 also has a widening part (not shown in the figure) so that the width of the middle part of the opening H172 is greater than the width of the two ends.
