Abstract
A kind of safe automobile air bag self adaptation vent structure, comprise bag and be arranged on the gas generator in bag, bag is provided with steam vent, its special character is: be sewed with and strengthen circle pieces of cloth in the inner corresponding steam vent of bag position, strengthen circle pieces of cloth middle part and be provided with centre bore, the hole shape of described centre bore is consistent with the hole shape of steam vent, and described bag forms two-layer bag and is stitched together after the line at the center of gas generator center and bag upper air-vent folds. The present invention has overcome traditional safe automobile air bag steam vent and has immobilized, and in gas replenishment process, a part of gas is by the shortcoming of discharging from traditional steam vent. Steam vent of the present invention in when inflation in closed condition; in the time that the bag of air bag is full of or when bag is under pressure; steam vent is opened automatically; reduce gas loss; make full use of the gas that generator produces; with buffering driver and crew's impact kinetic energy, thereby improve the protective value to driver and crew.
Description
Technical field
The present invention relates to a kind of safe automobile air bag self adaptation vent structure, can be used on various types of air bags, as driver air-bag, passenger air bag, installing side airbag etc.
Background technology
At present, generally, in the time that automobile bumps, be arranged on after the airbag deployment on automobile, gas generator is filled with gases at high pressure to air sac bag body, meanwhile, in order to improve the energy-absorbing buffering effect of air bag, is all designed with steam vent on the bag of air bag.
Steam vent on known air sac bag body is fixed, and when generator is in bag gas replenishment process, a part of gas is discharged from steam vent simultaneously, has reduced the protection effect of air bag.
Summary of the invention
The object of the invention is dissatisfied the problems referred to above that certainly prior art exists; improve a kind of safe automobile air bag self adaptation vent structure, can improve the charging efficiency of gas generator, reduce gas loss; with buffering driver and crew's impact kinetic energy, thereby improve the protective value to driver and crew.
Technical solution of the present invention is:
A kind of safe automobile air bag self adaptation vent structure, comprise bag 1 and be arranged on the gas generator 2 in bag 1, bag 1 is provided with steam vent 3, its special character is: be sewed with in the inner corresponding steam vent of bag 13 positions and strengthen circle pieces of cloth 4, strengthen circle pieces of cloth 4 middle parts and be provided with centre bore 401, the hole shape of described centre bore 401 is consistent with the hole shape of steam vent 3, and described bag 1 forms two-layer bag and is stitched together after the line at the center of gas generator 2 centers and bag upper air-vent 3 folds.
Described reinforcement circle pieces of cloth 4 are stitched together by two road sutures and bag 1.
The edge of steam vent 3 is positioned at the outside, edge of centre bore 401.
Described steam vent 3 is multiple.
Beneficial effect of the present invention is: overcome traditional safe automobile air bag steam vent and immobilized, in gas replenishment process, a part of gas is by the shortcoming of discharging from traditional steam vent. Steam vent of the present invention in when inflation in closed condition; in the time that the bag of air bag is full of or when bag is under pressure; steam vent is opened automatically; reduce gas loss; make full use of the gas that generator produces; with buffering driver and crew's impact kinetic energy, thereby improve the protective value to driver and crew.

Detailed description of the invention
Fig. 1 is the air bag schematic diagram of driver side, for the air bag of occupant-side safety airbag and other form, as installing side airbag etc., embodiments of the present invention are the same, are to be below described as example with the air bag of driver side and using a self adaptation steam vent.
As shown in Figure 1, the present invention has bag 1 and is arranged on the gas generator 2 in bag 1, and bag 1 is provided with steam vent 3. Steam vent 3 is a certain size circular hole or other hole shapes of cutting on bag 1, in Fig. 1, is described with circular row pore. Be sewed with in the inner corresponding steam vent of bag 13 positions and strengthen circle pieces of cloth 4(or other hole shape consistent with steam vent hole shape), in Fig. 1, shown in dotted line, it is the same with the hole shape of steam vent 3 and big or small identical that reinforcement circle pieces of cloth 4 middle parts are provided with the hole shape of centre bore 401 and centre bore 401; Or the edge of described steam vent 3 is positioned at the outside, edge of centre bore 401, and centre bore 401 is larger than steam vent 3. Strengthening circle pieces of cloth 4 is stitched together by suture 5.1 and 5.2 with bag 1, bag 1 is folding along the center line A in Fig. 1, described center line A is the line at gas generator 2 centers and bag upper air-vent 3 centers, by suture 5.3, folding two-layer bag 1 is stitched together, as shown in Figure 2.
As shown in Figure 3, when automobile bumps, 2 of gas generators are quick-fried, produce gases at high pressure, inflate in the inside of bag 1, and the expansion direction of airbag 1 is as shown in the arrow in Fig. 3. In Fig. 4, steam vent 3 is stitched together by suture 5.1 and 5.2 with bag 1, by suture 5.3, folding two-layer bag 1 is stitched together.
Along with gas generator 2 is constantly to the interior inflation of bag 1, airbag 1 launches, the steam vent 3 folding, and the inner mineralization pressure P of bag 1, makes bag 1 surface produce tension force F, and as shown in Figure 5, when bag internal pressure P fills when enough large, suture 5.3 is pulled off. Finally, folding bag 1 completes expansion, and steam vent 3 exposes completely, as shown in FIG. 6 and 7.
In Fig. 7, driver and crew and air bag contact site 6, oppress fully extended bag 1, and inner gas will be discharged from self adaptation steam vent 3, plays the effect of buffering and absorption kinetic energy.
In actual applications, the stitching intensity of suture 5.3 can be strengthened or weaken according to the volume of the pressure size of gas generator and air sac bag body 1, and the quantity of steam vent 3 on air bag can be one or more. When steam vent 3 is while being multiple, form two-layer bag and be stitched together after bag 1 is folding respectively along the line at the center of each steam vent 3 on gas generator 2 centers and bag.
The present invention sews up steam vent 3 by suture along airbag 1 expansion direction, steam vent 3 is before inflation and seals in gas replenishment process. In the time that the bag 1 of air bag is full of or when bag is under pressure, suture 5.3 ruptures, steam vent 3 is opened automatically, to cushion driver and crew's impact kinetic energy, thereby improves the protective value to driver and crew.
