Description

Technical Field

[0001] This utility model relates to the technical field of seat backrests, and in particular to an unlocking bracket for the backrest of a car seat. Background Technology

[0002] The "car seat frame" is the core support structure of a car seat. It is hidden under the seat filling and fabric and is the foundation and key to the entire seat function. Existing seat frames, such as the 4 / 6 split car seat frame disclosed in utility model patent CN208813038U and the rear seat frame disclosed in utility model patent CN221642336U, can all provide support for occupants.

[0003] However, during the production process, it was found that most of the backrest frames are installed on the seat frame, which requires assembly under the vehicle and then installation on the vehicle. This is time-consuming, labor-intensive, and inconvenient for maintenance, thus affecting practicality. Therefore, there is an urgent need for a car seat backrest unlocking bracket to improve the above problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a car seat backrest unlocking bracket that fits a seat cushion onto a seat cushion frame assembly, fits a backrest cushion onto a backrest frame assembly, supports the backrest frame assembly through an unlocking bracket assembly, supports the occupant's buttocks through the seat cushion frame assembly, and supports the occupant's back through the backrest frame assembly.

[0005] The present invention relates to an unlocking bracket for a car seat backrest, comprising a seat cushion frame assembly; and further comprising a backrest frame assembly and an unlocking bracket assembly, wherein the unlocking bracket assembly is mounted on the backrest frame assembly and the seat cushion frame assembly is located below the backrest frame.

[0006] The seat cushion frame assembly works in conjunction with the backrest frame assembly for support, and the unlocking bracket assembly allows for adjustment of the angle of the backrest frame assembly.

[0007] Install the seat cushion onto the seat frame assembly, install the backrest cushion onto the backrest frame assembly, support the backrest frame assembly by unlocking the bracket assembly, support the occupant's buttocks through the seat cushion frame assembly, and support the occupant's back through the backrest frame assembly.

[0008] Preferably, the seat cushion frame assembly includes a seat cushion frame, a rear tube assembly, a seat cushion wire assembly, and a mounting bracket. The rear tube assembly, seat cushion wire assembly, and mounting bracket are all mounted on the seat cushion frame, with the rear tube assembly located at the rear of the seat cushion frame, the seat cushion wire assembly located in the middle of the seat cushion frame, and the mounting bracket located at the bottom of the seat cushion frame. The rear tube assembly and seat cushion wire assembly work together to support the seat cushion cover, forming a seat cushion, and the mounting bracket secures the seat cushion frame to the vehicle.

[0009] Preferably, the backrest frame assembly includes a backrest frame one and a backrest frame two, both of which are mounted on the unlocking bracket assembly, and both the backrest frame one and the backrest frame two have a backrest center steel wire assembly in the middle; the backrest cover is supported by the backrest frame one and the backrest frame two to form a seat back.

[0010] Preferably, the unlocking bracket assembly includes a seat back center connecting bracket, two sets of backrest cover bracket assemblies, and two sets of lock mounting bracket welding assemblies. The seat back center connecting bracket is hinged to the bottom of backrest frame one and backrest frame two. The two sets of backrest cover bracket assemblies and the two sets of lock mounting bracket welding assemblies are respectively installed on backrest frame one and backrest frame two. The backrest cover bracket assembly provides an installation position for the unlocking structure, and the lock mounting bracket welding assembly provides an installation position for the lock. The seat back center connecting bracket supports backrest frame one and backrest frame two. After the seat is installed on the vehicle, backrest frame one and backrest frame two are rotated and installed on the vehicle. After unlocking, by moving backrest frame one or backrest frame two, backrest frame one or backrest frame two can rotate around the hinge point between the seat back center connecting bracket and backrest frame one and backrest frame two as the center, thereby adjusting the angle of backrest frame one or backrest frame two.

[0011] Preferably, both the left side of the backrest frame one and the right side of the backrest frame two are provided with an outer support wire assembly; the outer support wire assembly facilitates the support of the backrest cover.

[0012] Preferably, both the backrest frame one and the backrest frame two have a limiting bracket on the middle steel wire assembly in the backrest; this facilitates the installation of the child seat's safety buckle onto the limiting bracket.

[0013] Preferably, both the first backrest frame and the second backrest frame are provided with headrest supports at their tops; this facilitates the installation and fixation of the headrests and improves passenger comfort.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. By unlocking the bracket assembly, the seat cushion frame assembly and the backrest frame assembly become separate structures, improving the ease of installation;

[0016] 2. By unlocking the bracket assembly, the backrest frame assembly is supported, improving the convenience of adjusting the backrest angle;
