  • Patent number: 7331605
    Abstract: The invention relates to an airbag module for a motor vehicle comprising an airbag, a gas generator for inflating the airbag, and a housing for accommodating both the gas generator and the airbag. According to the invention, the airbag (1) and the gas generator (2) are arranged on opposite sides (30a, 30b) of a wall (30) of the housing (3).

  • Patent number: 7246820
    Abstract: An annular airbag is disclosed, of the type where the center piece (12) of the steering wheel cover (11) (mostly embodied as the emblem of the vehicle producer) remains in place during the unfolding process. In order to prevent a vehicle occupant impacting the hole arising above the center piece with an inflated airbag, the tubular region (17) of the airbag above the center piece is embodied such that the cross-sectional area thereof in the inflated state reduces in the direction of the upper plate of the airbag from the center piece (12). The above is achieved, for example, by means of a special forming of the tubular region, by provision of pockets (21) and/or folds (31), the use of special materials, a special fixing of the airbag to the airbag module (9), or the fitting of tension straps (50).

  • Publication number: 20060125220
    Abstract: The invention relates to an airbag module, especially a passenger airbag module, comprising a gas generator arranged in a module housing. The aim of the invention is to create an airbag module which provides the gas bag with a sufficient retaining capacity and enables a load-reducing gas bag deployment which can be variably influenced. According to the invention, the module housing (1) comprises a continuous gas outlet (6) on at least one side in the region of a gas bag (4) to be deployed, and at least one section (7) extending into the gas bag (4) is arranged in the region of the gas outlet. Alternatively, the section (11) can be arranged directly above the gas outlet (6a; 6b).

  • Patent number: 6422600
    Abstract: The invention relates to an airbag module comprising a gas generator, diffuser and a gas bag. The invention is characterized in that the gas generator (5) is arranged in a diffuser (1) or housing of the gas generator with a stepped structure when seen in a longitudinal section. The diffuser (1) or the housing of the gas generator extends in the lower region of the side wall (2) at a distance from the gas generator (5). The lower region of the side wall (2) extends beyond the gas generator (5) in the direction of the occupant. The diffuser (1) or the housing of the gas generator (5) has a smaller cross-section than the gas generator (5). Openings (6,16) through which the gas from the gas generator flows into the gas bag (10) are arranged in a perpendicular position to the occupant. The upper (4) and lower (2) regions of the side wall are connected to each other by at least one deformable center area (3) of the side wall.
