Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
205 words
In an air bag apparatus for impact protection in a motor vehicle having a passenger compartment, which apparatus comprises a unit which is adapted to be installed behind an exit opening provided in the front part of the passenger compartment and comprises an air bag which is folded up and is inflatable, a gas generator, a propellant, a housing which accommodates the air bag and the gas generator, and a flap covering the exit opening, the flap being adapted to swing upwardly and having a top edge which extends traversely to the direction of movement of the motor vehicle and is joined by a hinge portion to the adjoining edge of the exit opening, the improvement which comprises forming the housing with a half-rounded cross-section, providing a film (4,9) shrunk fit onto the housing (1,8) so as to close an opening provided in the housing (1,8) on the side facing the passenger compartment, the film being attached to the housing on its outside, the opening in the housing having a peripheral edge, the apparatus including sharp-edged projections (5, 10) secured on the outside of the housing (1, 8) along a part of the peripheral edge of the opening in the housing and contacting said film.
