Description

Technical Field

[0001] This utility model relates to the field of automotive safety products technology, specifically to a restraint system fixing structure and a child safety seat. Background Technology

[0002] Child safety seats typically feature a five-point harness as a restraint system to control the child and provide comprehensive protection. Additionally, since most new energy vehicles on the market now have panoramic glass roofs, child safety seats are often equipped with headrests for sun protection.

[0003] However, existing child safety seats lack a mechanism to secure the five-point harness after the headrest is installed. When a child is in the seat, the two straps of the five-point harness are pressed against their back, requiring the child to be seated on the backrest before the harness can be pulled out from behind; alternatively, the harness must be manually moved to the side of the seatback to lock it in place, making it inconvenient for the child to sit in the seat. Furthermore, manually moving the harness is also inconvenient when an adult is holding a child and needs to place them in the seat. Utility Model Content

[0004] To address at least one of the aforementioned problems, this utility model first provides a fixing structure for a restraint system, including a chair back, fixing seats, and a headrest frame. Two fixing seats are provided, spaced apart and installed on the chair back. The headrest frame is detachably connected to the two fixing seats. Each fixing seat has a first fixing part, and the headrest frame has two second fixing parts spaced apart. Both the first and second fixing parts are adapted to limit the movement of the seat belts. When the headrest frame is connected to the two fixing seats, the two seat belts can be respectively installed on the two second fixing parts, so that the two seat belts are located on the left and right sides of the occupant. When the headrest frame is detached from the two fixing seats, the two seat belts can be respectively installed on the two first fixing parts, so that the two seat belts are located on the left and right sides of the occupant.

[0005] Optionally, the first fixing part is a placement groove, which is formed by the fixing seat and the chair back being arranged at intervals.

[0006] Optionally, the fixing seat includes a connecting plate and a limiting plate. The limiting plate is fixedly disposed at one end of the connecting plate, and the top of the limiting plate protrudes from the connecting plate. The connecting plate is adapted to be connected to the chair back. The portion of the top of the limiting plate protruding from the connecting plate is arranged at intervals with the chair back to form the placement groove.

[0007] Optionally, the headgear frame includes a connecting base, the connecting base being adapted to be detachably connected to the fixing base, and the second fixing part being disposed on the connecting base.

[0008] Optionally, the second fixing part is an opening groove adapted for the seat belt to be inserted.

[0009] Optionally, the groove wall of the opening is provided with a clamping member, which is adapted to tighten and limit the seat belt inserted in the opening groove.

[0010] Optionally, the clamping member is inclined within the opening slot.

[0011] Optionally, the headliner frame further includes a front frame rod and a rear frame rod, the connecting base is connected to the rear frame rod, and the front frame rod is rotatably connected to the connecting base.

[0012] Optionally, a fixing block is fixedly provided on the connecting base, the front frame rod is rotatably connected to the fixing block, and a protrusion is also fixedly provided on the side of the connecting base where the fixing block is provided. The protrusion is located below the fixing block, and the protrusion and the fixing block are arranged at intervals to form the opening groove.

[0013] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0014] 1. After the fixed seat is installed on the backrest, it will form the first fixed part with the backrest. When the headrest is not installed, the two seat belts can be hung on the two first fixed parts, so that the two seat belts are located on both sides of the backrest. When the child sits down, there is no need to adjust the seat belts. After the child sits down, the seat belts are on the left and right sides of the child and will not be pressed behind the child. In addition, adults holding the child do not need to adjust the seat belts, which improves the convenience of children sitting down.

[0015] 2. After the headrest is installed on the fixed seat, the headrest frame will interfere with the first fixed part. At this time, the seat belt can be inserted into the second fixed part set on the headrest frame and limited. It can still achieve the same effect as fixing the seat belt to the first fixed part, so that the seat belt can be limited and fixed after the headrest is installed on the seat back. It is suitable for different scenarios.

[0016] 3. After the seat belt is inserted into the opening slot, the clamping part can cooperate with the slot wall to clamp and limit the seat belt, making it difficult for the seat belt to move or come out of the opening slot, thus improving the stability of the second fixing part in limiting and fixing the seat belt.

[0017] 4. The mounting bracket can be used as a standalone hook to limit and fix the seat belt, or as a base for installing the headliner frame. It has different functional attributes for different scenarios, making it a multi-purpose item and reducing costs.

[0018] 5. The first fixing part is a placement groove, and the second fixing part is an open groove. When the seat belt needs to be fixed, simply insert the seat belt into the placement groove or the open groove. The operation is simple. In addition, both the first fixing part and the second fixing part are grooves, which makes the structure simple and the production cost low.

[0019] In addition, this utility model provides a child safety seat, including the fixing structure of the restraint system as described above.

[0020] Compared to existing technologies, the child safety seat described in this utility model and the fixing structure of the aforementioned restraint system have the same advantages over existing technologies, which will not be repeated here. Attached Figure Description

Detailed Implementation

[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the following description is provided in conjunction with the appendix. Figure 1-8 This application will be described in further detail.

[0031] In a first aspect, embodiments of this utility model provide a fixing structure for a constraint system, referring to... Figure 1 and Figure 2 The restraint system's fixing structure includes a seat back 1, fixing seats 2, and a headrest frame 3. There are two fixing seats 2, symmetrically and spaced apart, installed on the seat back 1. The headrest frame 3 is detachably connected to the fixing seats 2; when the headrest is needed, the headrest frame 3 is installed on the fixing seats 2. Each fixing seat 2 has a first fixing part between itself and the seat back 1, and the headrest frame 3 has two symmetrically and spaced apart second fixing parts. When the headrest frame 3 is installed on the fixing seats 2, the two second fixing parts can respectively limit the two seat belts in the five-point restraint system of the child seat, so that the two seat belts are located on the left and right sides of the occupant's body. When the headrest is not installed, the two seat belts are limited by the two first fixing parts, so that the two seat belts are located on the left and right sides of the occupant's body. Thus, when a child gets on the seat back 1 to sit, the seat belts will not be pressed against the child's back and require additional adjustment, improving the convenience of the child getting into and sitting.

[0032] Reference Figure 2 and Figure 3 In this embodiment, the first fixing part is preferably a placement groove 21. When the seat belt needs to be limited by the first fixing part, it can simply be inserted into the placement groove 21 and hung on the fixing base 2. The structure is simple, the operation is convenient, and the production cost is low. In another embodiment, the first fixing part can be a female hook and loop fastener; the female hook and loop fastener is glued to the fixing base 2, and a male hook and loop fastener is sewn onto the seat belt. The male hook and loop fastener can be glued to the female hook and loop fastener, thereby limiting the seat belt to the first fixing part.

[0033] The two fixed bases 2 have the same structure. The following explanation will take the structure of one fixed base 2 as an example.

[0034] Combination Figure 2 Reference Figure 3 and Figure 4The fixing seat 2 includes an integrally formed connecting plate 22 and a limiting plate 23. The limiting plate 23 is located at the end of the connecting plate 22 away from the backrest 1, and the top of the limiting plate 23 protrudes from the connecting plate 22, forming an L-shaped plate with the connecting plate 22. Mounting grooves 11 are provided on both the left and right sides of the front of the backrest 1, and the connecting plate 22 is adapted to be inserted into the mounting grooves 11. A snap-fit ​​groove is provided on the outer side wall of the backrest 1, communicating with the mounting groove 11. A snap-fit ​​protrusion is integrally formed on the side wall of the connecting plate 22, adapted to snap into the snap-fit ​​groove to connect the fixing seat 2 with the backrest 1, improving the ease of assembly. When the snap-fit ​​protrusion snaps into the snap-fit ​​groove, the portion of the top of the limiting plate 23 protruding from the connecting plate 22 is spaced apart from the backrest 1, thus forming a placement groove 21.

[0035] In another embodiment, the limiting plate 23 can fit snugly against the backrest 1 without forming a gap. In this case, a placement groove 21 (first fixing part) can be directly formed on the top of the limiting plate 23, with the placement groove 21 extending through the fixing seat 2 in a left-right direction to facilitate seat belt insertion. In yet another embodiment, the placement groove 21 can be formed in front of the limiting plate 23 (on the same side as the front of the backrest 1), extending through the fixing seat 2 in a left-right direction. In yet another embodiment, the placement groove 21 can also be formed directly on the side wall directly in front of the backrest 1, extending through the wall thickness of the side wall of the backrest 1 in a left-right direction to facilitate seat belt insertion and positioning. In this case, the second fixing part is unnecessary, and the seat belt can still be inserted into the placement groove 21 after the headliner is installed.

[0036] Combination Figure 1 Reference Figure 5 and Figure 6 The headliner frame 3 includes a connecting base 31, a front frame rod 32, a rear frame rod 33, and a sunshade cloth (not shown in the figure). Two connecting bases 31 are symmetrically arranged, and both connecting bases 31 are fixedly connected to the rear frame rod 33. The front frame rod 32 is rotatably connected to the connecting base 31 via a pivot. One end of the sunshade cloth is fixedly connected to the front frame rod 32, and the other end is fixedly connected to the rear frame rod 33. The connecting base 31 is adapted to be detachably connected to the fixed seat 2. When the connecting base 31 is connected to the fixed seat 2, the rear frame rod 33 is connected to the chair back 1, and the rear frame rod 33 does not rotate relative to the chair back 1. When sunshade is needed, the front frame rod 32 is driven to rotate the sunshade cloth towards the front of the chair back 1 relative to the rear frame rod 33, thereby causing the sunshade cloth to unfold.

[0037] Combination Figure 2 Reference Figures 5 to 7The connecting base 31 has a slot at its bottom, and the portion of the limiting plate 23 protruding from the connecting plate 22 is suitable for insertion into the slot, allowing the connecting base 31 to be plugged into the fixing base 2, thus improving the convenience of installing and removing the headrest. In another embodiment, the connecting base 31 can be located in front of the fixing base 2 and connected to the fixing base 2 by bolts. After the connecting base 31 is plugged into the limiting plate 23, the connecting base 31 will also be inserted into the placement slot 21; at the same time, the rear frame rod 33 will also block the slot opening on one side of the placement slot 21 in the left and right directions, preventing the safety belt from being inserted into the placement slot 21. Therefore, the safety belt will be limited by the second fixing part set on the headrest frame 3.

[0038] Since the front frame rod 32 needs to rotate relative to the connecting base 31 when the headliner is in use, and the connecting base 31 is in a fixed state, the second fixing part is provided on the connecting base 31 in order to ensure the stability of the second fixing part after limiting the seat belt.

[0039] Combination Figure 2 Reference Figures 5 to 8 In this embodiment, the second fixing part is preferably located on the front of the connecting base 31 (on the same side as the front of the seat back 1), and preferably the second fixing part is an open groove 311, with both the left and right sides of the open groove 311 being open, thereby facilitating the insertion of the seat belt. In another embodiment, the second fixing part can be an L-shaped hook.

[0040] A fixing block 312 is integrally formed on the front of the connecting base 31. A shaft hole is formed on the outer wall of the fixing block 312. A rotating shaft is integrally formed inside the front frame rod 32 and is inserted into the shaft hole, allowing the front frame rod 32 to rotate relative to the rear frame rod 33. A protrusion 313 is provided below the fixing block 312 and is integrally formed with the connecting base 31. The protrusions 313 and the fixing block 312 are arranged at intervals to form opening slots 311, allowing the seat belt to be inserted into the opening slots 311 and hooked onto the protrusions 313 for restraint.

[0041] Combination Figure 2 Reference Figures 5 to 8A clamping member 34 is fixedly installed on the side of the protrusion 313 near the fixing block 312 (i.e., the groove wall of the opening groove 311). The clamping member 34 is adapted to limit the seat belt inserted in the opening groove 311 against the fixing block 312. The clamping member 34 includes a guide portion 341 and a bending portion 342. One end of the guide portion 341 is fixedly connected to the protrusion 313, and the other end extends obliquely towards the connecting base 31 and towards the fixing block 312. The bending portion 342 is integrally formed on the side of the guide portion 341 near the connecting base 31, and the end of the bending portion 342 near the connecting base 31 gradually bends towards the protrusion 313. This design allows for a larger opening at the end of the guide section 341 furthest from the bending section 342, which guides the insertion of the seat belt. The end of the guide section 341 closest to the bending section 342 can cooperate with the fixing block 312 to press the inserted seat belt against it. The bending section 342 provides space for the seat belt after bending, reducing the elastic resistance of the clamping member 34 when the seat belt is inserted into the opening slot 311, thus improving the smoothness of insertion.

[0042] In this embodiment, the clamping member 34 is preferably a plastic spring sheet integrally formed with the protrusion 313. In another embodiment, the clamping member 34 can be a metal spring sheet.

[0043] The implementation principle of the restraint system fixing structure in this application embodiment is as follows: the fixing seat 2 can be used as a separate hook to limit and fix the seat belt, and it can also be used as a base for installing the headrest frame 3. When the headrest is not installed, the two seat belts can be inserted into the two placement slots 21 respectively and hung on both sides of the seat back 1. When the child is riding, he / she can sit directly on the seat back 1 without having to adjust the seat belt. When the child gets off the seat back 1, the seat belt is inserted into the two placement slots 21 and is limited, so that the seat belt will not interfere with the child, and the child can get off more smoothly and conveniently.

[0044] When installing the headliner, simply plug the connecting base 31 into the limiting plate 23. However, after the connecting base 31 and the limiting plate 23 are plugged in, the placement slot 21 will be blocked. At this time, the seat belt can be inserted into the opening slot 311 of the connecting base 31, so that the two seat belts are still located on both sides of the backrest 1, improving the convenience and smoothness of getting in and out of the child. The clamping member 34 can cooperate with the groove wall of the opening slot 311 to clamp and limit the seat belt, making it difficult for the seat belt to move or come out of the opening slot 311.

[0045] Secondly, another embodiment of the present invention provides a child safety seat with a fixing structure that incorporates the restraint system described in the first aspect, making it more convenient for children to get in and out of the safety seat.
