Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to an ISOFIX bracket structure which can be used for a front seat of an automobile. Background Art

[0002] ISOFIX interface fixation is a major installation and fixing method for child safety seats. The fixing points of child safety seats in traditional seat frames are mostly welded with steel wire hooks at the rear tube to achieve the lower fixing point, and welded with brackets on the backrest side panels to achieve the upper fixing point. This design is mostly used for rear seat frames of cars without high profile. For front seat frames of cars with high profile, the design is mostly in the form of large brackets that are inconvenient to disassemble.

[0003] To this end, some people have designed an ISOFIX fixing structure that can be used for the front seats of cars, such as the patent with application number CN202120281770.3 that discloses an ISOFIX fixing component for the front seats of cars, including an ISOFIX welding assembly, and the ISOFIX welding assembly includes two L-shaped ears and an ISOFIX bracket. The two L-shaped ears are welded and fixed to the left and right ends of the ISOFIX bracket respectively. ISOFIX interfaces are provided at the positions near the ends of both ends of the ISOFIX bracket. The ISOFIX interface is an n-type fixing steel wire. The n-type fixing steel wire is vertically fixed to the ISOFIX bracket through two bottom legs, and the top of the n-type fixing steel wire is inclined toward the seat frame. A LATCH interface is provided in the middle of the ISOFIX bracket. The LATCH interface is a bow-shaped fixing steel wire. The bow-shaped fixing steel wire is horizontally fixed to the rear wall of the ISOFIX bracket through the legs at both ends.

[0004] The ISOFIX fixing assembly for the front seat of the car provided by the above patent has a seat frame mounting hole set between the non-welded surface of the L-shaped support ear and the two bottom legs of the n-shaped fixing wire. The ISOFIX fixing assembly is fixed to the seat frame by self-tapping bolts passing through the seat frame mounting holes and nuts. When installing it on the seat frame, it is necessary to align the mounting holes of the ISOFIX fixing assembly and the seat frame. Since it is provided with multiple mounting holes and no positioning structure, it is difficult to match the mounting holes of the seat frame with the mounting holes set on the seat frame one by one, resulting in installation difficulties. Utility Model Content

[0005] The utility model aims to provide an ISOFIX bracket structure that can be used for the front seats of automobiles, aiming to improve the existing ISOFIX fixing components of the front seats of automobiles, which have the problem that, due to the lack of a positioning structure, it is difficult to match the mounting holes of the seat cushion frame with the mounting holes provided on the seat cushion frame one by one, resulting in the problem of difficult installation.

[0006] The utility model is implemented as follows: an ISOFIX bracket structure that can be used for a front seat of a car comprises a mounting bracket, two steel wire hooks are sequentially arranged on the mounting bracket along its length direction, a connecting frame portion is arranged on the mounting bracket between the two steel wire hooks; a clip nut is respectively arranged at both ends of the mounting bracket, a mounting bolt is threadedly installed on the clip nut, and a flange hook is also respectively arranged at both ends of the mounting bracket.

[0007] Furthermore, the two steel wire hooks are in an N-shaped structure, and the steel wire hooks are connected to the mounting bracket by welding.

[0008] Furthermore, the connecting frame portion is located in the middle of the two wire hooks.

[0009] Furthermore, the connecting frame portion is in the shape of a sun, including a hanging rod in the middle and connecting openings on both sides of the hanging rod.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. The utility model does not have the problem that the installation process of the existing automobile front seat ISOFIX fixing components requires the installation holes between the two interconnected parts to be aligned before installation can be carried out. The installation steps of the utility model are simple and convenient, and it is easy to disassemble after installation.

[0012] 2. When the utility model is installed on the seat cushion frame assembly, due to the provision of the clip nuts, it is possible to avoid welding the mounting nuts on the seat cushion side panels of the seat cushion frame assembly. For seats with or without ISOFIX configuration, no additional parts will be added to avoid management waste. The mounting bolts are installed from the outside to the inside, avoiding the problem of insufficient installation space caused by installation from the inside to the outside, and also avoiding the problem of possible mutual interference between the mounting bolts and the seat back connection bolts caused by installation from the inside to the outside. The utility model can be used in a more compact frame design.

[0013] 3. The mounting bracket of the utility model is provided with a wire hook as the lower fixing point of the child safety seat ISOFIX and a connecting frame part as the upper fixing point of the child safety seat ISOFIX. Compared with the traditional structure, it can be used on the front seats of the car with high profile. In addition, the structure of the utility model is simpler, which can reduce the amount of parts, reduce the weight of the frame, reduce one welding process, and save costs.

[0014] 4. The utility model can be used not only on the front seats of a car with high profile, but also on the middle row independent seats with high profile, and can also be used on the zero-gravity seats with adjustable seat cushion inclination. BRIEF DESCRIPTION OF THE DRAWINGS
