Abstract
The invention relates to a front airbag module for an automotive vehicle comprising an inflatable cushion (11) that can be inflated with the gas produced by a generator, including at least one venting opening (17) and a venting regulation device formed by a flexible material part (21) joined to the inflatable cushion (11) on the periphery or near zones of said venting opening (17) such that it can completely or partially close or uncover it, preventing or allowing the output of gas, and a stress member (23) joined at one of its ends to said flexible material part (21) and at the other end to the inflatable cushion (11), the geometric configurations of said stress member (23) and of said flexible material part (21) being established such that the opening degree of the venting opening (17) is determined by the stress level in the stress member (23) during cushion (11) deployment.
