Field of the Invention The present invention relates to a vehicle air bag for inflating an air bag between an occupant and an indoor part in front of the occupant to prevent the occupant from directly contacting the indoor part in a vehicle collision. It relates to a bag system.

参照）。2. Description of the Related Art It is well known in the prior art to mount an airbag system for restraining the occupant by restraining the movement of the occupant by an inflated airbag when the vehicle collides with a vehicle such as an automobile (for example, an actual flat tire). No. 1-150155).

ッグの衝撃を緩和するようにしている。In this type of airbag system, a vehicle collision is detected by a sensor that detects the vehicle deceleration at the time of a collision, and the detection signal is used to operate an inflator provided in front of the occupant to generate gas. The gas is sent into the airbag that has been folded so far to inflate the bag, and the occupant is received by the airbag to protect the occupant. An exhaust hole is formed in such an airbag, and by discharging a part of the gas in the airbag from the exhaust hole, when an occupant hits the airbag, the repulsion of the occupant is mitigated, and the air bag for the occupant is restrained. I try to absorb the shock.

た。Such an air bag is configured to complete inflation in an extremely short time after the sensor detects a collision, for example, a short time of about 30 msec, and reliably receive the occupant. Has been done. However, since the exhaust hole is formed in the airbag as described above, the gas constantly flows out from the exhaust hole from the folded state of the bag until the gas is fed and the inflation is completed. To configure the airbag system so that the time from the start of inflation of the bag to the completion of inflation is extremely short as described above, the total cost is high and the airbag system is expensive. I couldn't avoid the drawback.

For example, although not shown in the drawing, the inflator is arranged on a support plate provided on the central hub portion of the steering wheel located in front of the driver's seat in the vehicle compartment, and the airbag 1 has the gas inflow hole 3 of the inflator. The peripheral portion of the gas inflow hole 3 is fixed to the support plate in a state of being fitted to. The airbag 1 is stored in a cover attached to the support plate in a folded state.

止め、乗員を保護する。The airbag system according to the present invention has, in addition to the airbag 1 and the inflator described above, a sensor (not shown) arranged at a proper position on the vehicle body, and this sensor detects a collision of an automobile. Upon detection, the detection signal causes the inflator to operate and generate, for example, nitrogen gas. The gas thus generated is sent into the airbag 1 through the gas inflow hole 3 shown in FIG. 1, whereby the airbag 1 starts inflating, and the pressure thereof causes the above-mentioned cover surrounding the airbag 1 to be inflated. To break. Then, the airbag 1 largely inflates between the steering wheel and the occupant, and the front surface side 4 receives the body of the occupant, particularly the face thereof, and protects the occupant.

出させる適数の排気孔７が形成されている。When the inflated airbag 1 receives an occupant, it is necessary to discharge a part of the gas in the airbag 1 for the purpose of reducing the impact on the occupant. For this reason,
In the present invention, as illustrated in FIGS. 1 to 3, a proper number of four through holes 5 are formed in the back surface side 2 of the airbag 1, and in the example of the drawing, these through holes 5 are formed. For example, a sheet-like elastic member 6 made of rubber or soft synthetic resin is provided. That is, the periphery of the elastic member 6 is fixed to the airbag portion around the through hole 5 by, for example, sewing or an adhesive, and the through hole 5 is covered by the elastic member 6. Reference numeral 8 indicates the sewn portion. Each elastic member 6 is formed with an appropriate number of exhaust holes 7 for exhausting the gas inside the airbag 1.

FIG. 4 is a graph in which the pressure inside the air bag is plotted vertically and the time is plotted on the horizontal axis, and the solid line A shows changes in the inner pressure of the air bag 1 shown in FIGS. 1 to 3.

膨張を完了する。In FIG. 4, at time t 1 , the airbag 1 is
The internal pressure of P shows a peak value P 1 , which is the pressure when the airbag 1 fed with gas breaks the cover as described above. After breaking the cover, the pressure in the airbag is reduced once, according to the amount of gas fed into the inside is increased, the pressure in the airbag is increased again, the maximum value P 2 at the time indicated by t 2 Then, the inflation of the airbag 1 is completed.

る。When the pressure inside the airbag 1 rises again after the cover is ruptured, a tensile force is applied to the airbag 1 and the elastic member 6, and the magnitude of the tensile force is increased.
Increases with the expansion of. When such a pulling force is applied, the airbag itself does not greatly undergo tensile deformation because it is made of rubber-coated cloth as described above, but since the elastic member 6 is made of an elastic material such as rubber, the airbag 1 As the internal pressure rises, the elastic member 6 is tensilely deformed, and when the internal pressure reaches the maximum value P 2 at time t 2 , the elastic member 6 is largely elastic as shown in FIGS. 5 and 6. Deform. Therefore, the exhaust holes 7 formed in the elastic member 6
Also greatly expands as shown in FIGS. 5 and 6. The arrow in FIG. 6 indicates the pressure inside the airbag.

実に乗員を受け止めることができる。As described above, the size of the exhaust hole 7 is kept small at a stage immediately after the cover is cut by the airbag 1, but the airbag 1 continues to expand after that, and the internal pressure thereof reaches the maximum value P. Exhaust hole 7 expands greatly just before reaching 2 . At this time, in the initial stage when the expansion starts, the size of the exhaust hole 7 is small as described above, so that the amount of gas flowing out from this is extremely small. Therefore, the airbag 1 inflates quickly and completes the inflation in a very short time. Therefore, the occupant can be reliably received by the airbag 1.

の衝撃を確実に緩和することができる。On the other hand, as the inflation of the airbag 1 progresses and the exhaust hole 7 expands greatly immediately before the internal pressure thereof reaches the maximum value P 2 , the amount of gas flowing out from the inside of the airbag 1 through this is increased. Increase. Therefore, when the occupant hits the inflated airbag 1, the pressure inside the airbag 1 does not become too high, and even after the occupant hits the airbag 1, Since the gas is effectively discharged through the expanded exhaust hole 7, it is possible to reliably reduce the impact on the occupant.

The impact on the can be effectively softened.

材６の形態は適宜選択することができる。In the embodiment shown in FIGS. 2 and 3, the elastic member 6 is formed so that the elastic member 6 projects outward before the gas is sent into the airbag 1. As shown in FIG. 7, the elastic member 6 may be formed so that the elastic member 6 is substantially flush with the airbag 1 before the airbag 1 is inflated. Thus, the form of the elastic member 6 can be appropriately selected.
