Plastic film airbag

摘要

An inflatable occupant restraint module including a housing mounted in the vehicle and having an interior, a deployable airbag contained within the housing interior prior to deployment, an inflator coupled to the housing for inflating the airbag by supplying a gas into the airbag interior and an initiator for initiating the supply of gas into the airbag interior in response to a crash of the vehicle. The airbag includes at least one non-perforated sheet of film defining the airbag interior and a thermoplastic elastomeric material arranged at specific locations in connection with the sheet(s) of film such that the locations are thicker in comparison to an average thickness of the sheet(s) of film. Another embodiment of the inflatable occupant restraint assembly includes at least one airbag module mounted in the vehicle and having inflatable airbags, a net surrounding the airbags for retaining the same in an interior thereof, an inflator arranged in connection with the airbags for inflating the same and an initiator for initiating the inflator in response to the crash of the vehicle. The airbags preferably include the thermoplastic elastomeric material as described above. The net is made of an interlaced network of material strips and defines an interior volume less than the volume of the airbags when inflated.
