Automotive vehicle airbag arrangement, has elastic membrane which, on deformation due to collusion of the user with the bag, allows slow escape of gas through vent

摘要

The airbag has an elastic membrane (3) with a vent arrangement (2). Normally the membrane covers the vent, but deforms when the internal pressure of the bag exceeds a threshold value, thus allowing leakage of the gas through the vent to cushion the impact.
