AI Technical Summary
When a car crashes on the side, the plastic skeleton is prone to breaking, causing debris to splash, which cannot effectively protect passenger safety, and increasing the thickness of the plastic skeleton cannot completely solve the problem.
A wire skeleton is used instead of a plastic skeleton, and is combined with airbags, skins, foam and other components. It is connected through airbag fixing nuts and staples to form a side pad structure with foamed steel skeleton integrated to avoid fragmentation during airbag blasting.
It effectively avoids the breakage of plastic skeletons, provides support, reduces damage to passengers, and meets the requirements of car safety and cost.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of automobile interior decoration, and relates to a C-pillar wing of an automobile, in particular to a side pad with a steel wire frame suitable for a C-pillar wing of an automobile. Background Art
[0002] With the development of the automobile industry and the continuous advancement of technology, high-tech and safe products have increasingly entered our lives. End users have more and more requirements for passive safety functions and quality of vehicles. In order to improve the safety factor of the whole vehicle, more and more cars are equipped with airbags on the side wings between the second row of seats and the C-pillar. When the whole vehicle hits the side, if the airbag activation point is triggered, the airbag will be deployed to protect the rear passengers and reduce the damage to the human body when the vehicle hits the side. The general composition of the side wing is plastic parts, skin, foam, and airbags; because the airbag is directly fixed on the plastic frame, when the vehicle collides, the airbag will contact the plastic frame at the first time when it is deployed. At the same time, under low temperature conditions, the performance of the plastic frame is reduced, so the impact force of the airbag explosion will shatter the frame, and there will be a risk of debris splashing. Therefore, the shattering of the plastic frame does not meet the safety requirements of the whole vehicle, and increasing the thickness of the plastic frame cannot completely solve the problem. At this time, we use a steel wire frame instead of a plastic frame and fix it on the C-pillar side wing to avoid the shattering of plastic parts. When the airbag explodes, the airbag bag unfolds and hits the frame. Due to its steel wire structure, the plastic frame is prevented from breaking, thus meeting the cost and safety requirements of the car. Utility Model Content
[0003] The utility model aims to provide a side pad with a steel wire frame suitable for the side wing of the C-pillar of an automobile, so as to solve the problem of damage to the human body caused by the shattering and splashing of the plastic frame of the original automobile C-pillar side pad when encountering an impact explosion.
[0004] The utility model solves the technical problem by adopting the following technical solutions:
[0005] A side pad with a steel wire frame suitable for the side wing of a C-pillar of an automobile comprises: a steel wire frame 1, a skin assembly 2, a foam 3, an airbag 4, an airbag fixing nut 5, and a staple 6, wherein the airbag 4 is covered and fixedly connected with the airbag bag 2-2 in the skin assembly 2; the bolts on the airbag 4 are connected with the round hole A and the strip hole B on the steel wire frame 1 through the airbag fixing nut 5; the foam 3 and the steel wire frame 1 are foamed and integrally formed (the steel wire frame is placed in a foaming mold); the skin assembly 2 is fixed on the foam 3 through the staple 6. When the airbag explodes, the airbag bag is unfolded and has a strong impact on the surrounding area. At this time, the steel wire frame provides a certain support to prevent the flying debris from causing harm to personnel when the plastic parts are broken.
[0006] The steel wire skeleton 1 is provided with a circular hole A and a strip hole B (such as Figure 3 shown);
[0007] The skin assembly 2 is composed of a skin panel 2-1 and an airbag bag 2-2, wherein the skin panel 2-1 and the airbag bag 2-2 are sewn together by sewing thread;
[0008] The steel wire skeleton 1 is a welded skeleton;
[0009] The skin panel 2-1 is leather or leather;
[0010] The foam 3 is a mixed foaming structure of Poly and ISO;
[0011] The airbag 4 is a safety airbag;
[0012] The air bag fixing nut 5 is a standard metal part.
[0013] The advantages and positive effects of the utility model are:
[0014] The utility model has reasonable design, simple structure, convenient assembly and improved vehicle driving safety, and the cost can meet the cost control requirements of most main engine manufacturers. BRIEF DESCRIPTION OF THE DRAWINGS
