Abstract: An airbag module for installation in a motor vehicle has an airbag made of an airbag fabric and folded up before being triggered by an inflation device. The airbag fabric has at least one slit forming an adaptive ventilation opening and a retaining strap, which at one end is held releasably on a retainer on the airbag module and at the other end is connected fixedly to the airbag. The slit (11) is cut into the airbag fabric and has two ends configured to prevent the slit (11) from tearing when pressure is applied. The retaining strap is arranged on the inside of the airbag and is guided through a securing loop (17) attached to the airbag fabric opposite the fixed end (14) of the retaining strap across the slit (11) toward the retainer.

Abstract: An airbag for a vehicle occupant protective system comprises an inflatable cushion, a cinch tube circumventing a vent aperture disposed in the cushion, and a draw element guided in a circumventing channel of said cinch tube and being coupled to a surface of said cushion such that deployment of said cushion causes said draw element to contract said cinch tube. The airbag comprises a contraction limiting arrangement adapted to limit the contraction of said cinch tube by said draw element to a predetermined minimum free diameter d of at least 20% relative to the free diameter D of the open cinch tube.

Abstract: An air-bag housing comprising a rectangular frame (1) defining an opening and having a mounting arrangement in the form of flanges (7) to mount the frame in position within a motor vehicle. The frame supports a housing-forming element (21) formed, for example, of fabric. This forms a housing having walls (71, 72) and a floor. The walls (71, 72) are formed seamlessly by folding the fabric in half about a fold-line, and tucking one end of the fold-line into the other end of the fold-line, and inserting the frame between the pieces of fabric to lie adjacent the fold-line. The floor is formed by a plurality of floor-forming tabs (25, 26, 35, 36 etc) carried by the fabric forming the side-walls of the housing. The tabs are folded inwardly to at least partly overlie each other and are secured in position to form the floor of the housing by studs (15, 16, 17, 18) provided on the inflator which pass through co-aligned apertures (27, 30, 38, 39) in the floor-forming tabs (25, 26, 35, 36 etc).

Abstract: An airbag module and instrument panel assembly for a motor vehicle having at least one ventilation outlet and a ventilation duct attached thereto and arranged behind an instrument panel. The airbag module is fastened behind the instrument patent and has a gas generator and a folded airbag arranged within its housing wherein a ventilation outlet is closed by a grid that opens when the airbag module is triggered and is provided within the instrument panel for the unfolding airbag. The airbag module is arranged adjacent to the ventilation duct in such a manner that when the airbag module is triggered, the airbag unfolds into the ventilation duct and from there unfolds out of the instrument panel through the ventilation outlet. The pressure of the unfolding airbag moves away from the ventilation outlet which is arranged within the instrument panel.

Abstract: An airbag module in a motor vehicle having a modular casing installed behind at least one opening flap built into the instrument panel is characterized in that the disk-shaped gas generator, including the modular casing surrounding it, is arranged on-edge at an angle to the plane of the instrument panel, its narrow side being defined by the gas-discharge openings arranged on its perimeter, and the folded airbag is arranged at least partially between the narrow side of the gas generator and the opening flap.

Abstract: An airbag system for jointly supporting at least two vehicle occupants inside a motor vehicle in case of an accident with at least two separate airbags inflatable with a gas supplied by a gas generator. The airbag system has at least two airbags (14, 15) folded into a common housing (10) to be arranged in the dashboard of the motor vehicle. The airbags are connected to a common gas generator (11) having at least two outflow areas (13, 18, 19) assigned to the at least two airbags (14, 15). Each airbag (14, 15) is sealed by a deflector (16, 17) inserted therein against the respectively other airbag (14, 15), and the airbags are fixed inside the housing (10).

Abstract: An airbag module with a gas generator, a gas bag, a housing containing an exit opening for the deploying gas bag, and a holder. The gas generator and holder are located inside the gas bag, and the gas generator is fixed to the housing. The holder (19) has a support area (20) and at least one deflector segment (21, 22) directed toward the exit opening (13). The holder is placed between the gas generator (14) and the housing (10). The deflector segment at least partially surrounds the gas generator (14) and directs the gas generated by the gas generator (14) into at least one of a plurality of fold packets (16, 17, 18) of the gas bag (15) placed on both sides of the deflector segment (21, 22).
