Description

side curtain air bag local reinforcing structure, side curtain air bag and automobile

Technical Field

The utility model belongs to the automobile manufacturing field, in particular to kinds of side air curtain air pocket local additional strengthening and side air curtain air pocket and car.

Background

As the safety technology of automobiles is improved, the side air curtain of the automobile is popularized, the problem that the part of the side air curtain is locally impacted and broken by high-temperature gas when the side air curtain is unfolded in a high-temperature environment happens occasionally, , the air curtain can not be unfolded completely, the protection performance of passengers is influenced, when the side air curtain gas generator acts in the high-temperature environment, the pressure of an air outlet is higher than that of the air outlet at normal temperature, the impact force on an air bag is also increased, meanwhile, the strength of the air bag in the high-temperature environment is poor, the air bag of the air curtain is easy to break, and the leaked high-temperature gas easily burns the skin of the face and the neck of the passengers, so.

The gas generator for the side air curtain is provided with an air guide pipe, the air outlet direction of the air guide pipe is opposite to a dead zone on an air bag of the air curtain, and the suture position of the dead zone is easy to crack when the side air curtain is unfolded at high temperature, the position of the dead zone is related to the protection area of the side air curtain and the protection performance of the head, and denier determines that the position cannot be changed, so that the area needs to be reinforced, the existing structure is shown in figure 1, but the structure has the defects:

1, a reinforcing sheet is arranged in the dead zone, but the reinforcing sheet with the existing structure cannot protect the air bag;

2, the needle point can scratch the air bag in the sewing process of the existing structure, and the strength of the part is reduced.

Disclosure of Invention

The utility model aims at providing kinds of local additional strengthening of side gas curtain air pocket and car, when solving side gas curtain and launching under high temperature environment, the local cracked problem of high temperature gas impact.

The utility model aims at realizing through the following technical scheme:

local reinforcing structure of side air curtain air bag, the reinforcing structure sets up on the dead zone of the air curtain air bag that the direction of giving vent to anger just right of air duct, and this reinforcing structure includes 2 main parts and 4 reinforcing pieces, sets up 2 reinforcing pieces inside and outside respectively of each main part, is inside reinforcing piece and outside reinforcing piece respectively, sews up at through the suture between main part and reinforcing piece.

In step , 2 reinforcement panels on each side of each main panel were sewn at by outside stitches and 2 main panels and 4 reinforcement panels were sewn at by inside two stitches.

, the main sheet and the reinforcing sheet are both made of PA66 or PET.

And , the 2 main pieces are two cloth pieces with the same shape.

, the diameter of the reinforcing plate is larger than the diameter of the dead zone sewing coil and smaller than the width of the main plate, and the diameter is preferably 100 mm.

The utility model discloses an in addition aspect:

side curtain air bag, wherein the air bag is provided with the side curtain air bag local reinforcing structure.

The utility model discloses an in addition aspect:

, the automobile is characterized in that the automobile is provided with the side air curtain air bag.

The utility model discloses compare prior art's beneficial effect does:

local additional strengthening of side air curtain air pocket, through the mode that increases screening glass and sewing coil, solve the problem of air pocket local rupture, particularly, through increasing the inboard intensity of suture promotion air pocket to inside reinforcing piece, through outside increase reinforcing piece, avoid the injury of needle point to promote the intensity in the air pocket outside.

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, and it is obvious that the drawings in the following description are embodiments of the present invention, and other drawings can be obtained by those skilled in the art without creative efforts.

Drawings

FIG. 1 is a schematic view of a prior art airbag reinforcement structure;

FIG. 2 is a schematic view of a side curtain airbag partially reinforced structure according to the present invention;

FIG. 3 is a sectional view of a partial reinforcing structure of the side curtain air bag.

Detailed Description

As shown in figures 2 and 3, the embodiment provides partial reinforcing structures of side air curtain air bag, the reinforcing structure A is arranged on the dead zone of the air curtain air bag facing to the air outlet direction of the air guide pipe, the reinforcing structure comprises 2

main sheets

1, 2 and 4 reinforcing sheets 4, 2 reinforcing sheets are respectively arranged inside and outside each main sheet, namely an inner reinforcing sheet 4-1 and an outer reinforcing sheet 4-2, the main sheets and the reinforcing sheets are sewn at through

sewing threads

3, 2 reinforcing sheets on both sides of each main sheet are sewn at through outer sewing threads 3-1, 2 main sheets and 4 reinforcing sheets are sewn at through inner two sewing threads 3-2, the inner reinforcing sheets are used for reducing the impact of high-temperature air on the main sheets, the outer reinforcing sheets are used for avoiding the scratch of the main sheets when sewing needle points, and additional sewing coils (namely, the outer sewing threads 3-1) are the same as other threads on the air bag.

, the main piece and the reinforcing piece are made of PA66, 2 main pieces are two cloth pieces with the same shape, the reinforcing piece can be obtained by cutting off leftover materials, and the diameter of the reinforcing piece is 100 mm.
