ABSTRACT:
An inflatable airbag is disclosed which defines an inflatable chamber. The airbag generally includes an inner elastic membrane provided in the peripheral wall of the airbag and a vent-hole formed through the elastic membrane. An outer membrane is provided on the outside of the airbag that extends across at least part of the inner membrane and the vent-hole. The outer membrane defines a pucker over the inner membrane and the vent-hole. The pucker is open so as to define an outlet flow path from the vent-hole when the inner membrane is spaced from the pucker. The inner membrane is configured to stretch and seal against the pucker around the vent-hole when the internal pressure within the inflatable chamber exceeds a predetermined value.
