Abstract
A self-adaptive gas vent structure of an automobile safety airbag comprises a bag body and a gas generator mounted in the bag body, and a gas vent is formed in the gas body. The self-adaptive gas vent structure of the automobile safety airbag is characterized in that a reinforcing circular cloth piece is sewn at the position, corresponding to the gas vent, inside the bag body, a center hole is formed in the middle of the reinforcing circular cloth piece, the hole shape of the center hole and the hole shape of the gas vent are the same, and the gas body is folded along the connecting line of the center of the gas generator and the center of the gas vent in the bag body and then forms two layers of bag bodies which are then sewn together. The defects that the gas vent of a traditional automobile safety airbag is fixed and unchanged, and part of gas is discharged out from a traditional gas vent in the air inflation process are overcome. The gas vent is in the closed state during air inflation, when the bag body of the airbag is fully inflated or the bag body is subjected to pressure, the gas vent can be opened automatically, gas loss is reduced, the gas generated by the generator is fully utilized, the impact kinetic energy of a driver and passengers can be buffered, and therefore the protection performance to the driver and the passengers is improved.
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 safety air bags, as driver air-bag, passenger air bag, installing side airbag etc.
Background technology
At present, generally, when automobile bumps, be arranged on after the airbag deployment on automobile, gas generator is filled with high pressure gas to air sac bag body, meanwhile, in order to improve the energy-absorbing buffering effect of air bag, is all designed with deflation hole on the bag of air bag.
Deflation hole on known air sac bag body is fixed, and when producer is in bag gas replenishment process, a part of gas is discharged from deflation hole 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 charge 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 deflation hole 3, its special character is: in the inner corresponding deflation hole of bag 13 positions, be sewed with and strengthen circle cloth sheet 4, strengthen circle cloth sheet 4 middle parts and be provided with centre hole 401, the hole shape of described centre hole 401 is consistent with the hole shape of deflation hole 3, and described bag 1 folds the two-layer bag of rear formation and is stitched together along the line at the center of gas generator 2 centers and bag upper air-vent 3.
Described reinforcement circle cloth sheet 4 is stitched together by two road sutures and bag 1.
The edge of deflation hole 3 is positioned at the outside, edge of centre hole 401.
Described deflation hole 3 is a plurality of.
Beneficial effect of the present invention is: overcome traditional safe automobile air bag deflation hole and immobilized, in gas replenishment process, a part of gas is by the shortcoming of discharging the deflation hole from traditional.Deflation hole of the present invention in when inflation in closed condition; when the bag of air bag is full of or when bag is under pressure; deflation hole is opened automatically; reduced gas loss; make full use of the gas that producer produces; with buffering driver and crew's impact kinetic energy, thereby improve the protective value to driver and crew.

The specific embodiment
Fig. 1 is the safety air bag schematic diagram of driver side, air bag for 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 safety air bag of driver side the self adaptation deflation hole of usining.
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 deflation hole 3.Deflation hole 3 is a certain size circular hole or other hole shapes of cutting on bag 1, in Fig. 1, with circular row pore, is described.In the inner corresponding deflation hole of bag 13 positions, be sewed with and strengthen circle cloth sheet 4(or other hole shape consistent with deflation hole hole shape), in Fig. 1, shown in dotted line, it is the same with the hole shape of deflation hole 3 and big or small identical that reinforcement circle cloth sheet 4 middle parts are provided with the hole shape of centre hole 401 and centre hole 401; Or the edge of described deflation hole 3 is positioned at the outside, edge of centre hole 401, and centre hole 401 is larger than deflation hole 3.Strengthening circle cloth sheet 4 is stitched together by suture 5.1 and 5.2 with bag 1, bag 1 is folding along the line of centers A in Fig. 1, described line of centers 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 high pressure gas, in the inside of bag 1, inflate, and the expansion direction of airbag 1 is as shown in the arrow in Fig. 3.In Fig. 4, deflation hole 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 deflation hole 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 deflation hole 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 deflation hole 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 deflation hole 3 on air bag can be one or more.When deflation hole 3 is while being a plurality of, form two-layer bag and be stitched together after bag 1 is folding respectively along the line at the center of each deflation hole 3 on gas generator 2 centers and bag.
The present invention sews up deflation hole 3 by suture along airbag 1 expansion direction, deflation hole 3 is before inflation and seals in gas replenishment process.When the bag 1 of air bag is full of or when bag is under pressure, suture 5.3 fractures, deflation hole 3 is opened automatically, to cushion driver and crew's impact kinetic energy, thereby improves the protective value to driver and crew.
