ABSTRACT:
An inflatable occupant restraint device in an occupant protection system of a vehicle including a housing mounted in the vehicle and having an interior, at least one deployable airbag contained within the housing interior prior to deployment, an inflator coupled to the housing for inflating the airbag, the airbag being attached to and in fluid communication with the inflator, and an initiator for initiating a gas supply mechanism in the inflator to supply gas into the interior of the airbag in response to a crash of the vehicle. The airbag is made of a first non-perforated sheet of film and a member arranged in connection with the film sheet for arresting the propagation of a tear in the film sheet. The member is (i) a network of at least bi-directional material strips or (ii) a second non-perforated sheet of film having substantially anisotropic tear properties whereby the direction of least tear resistance of the second sheet of film is different than a direction of least tear resistance of the first sheet of film.
