  • Patent number: 7722077
    Abstract: An airbag configuration provides an airbag outlet opening in a front instrument panel wall region. A given safety distance is provided between the airbag outlet opening and a potential head impact region of a vehicle occupant. The potential head impact region is provided in a head-impact instrument panel wall region adjoining the front instrument panel wall region in a direction away from a windshield and towards the vehicle interior. The safety distance is provided in such a manner that the airbag, after advancing in the direction of the vehicle interior by a distance corresponding to the safety distance between the airbag outlet opening and the potential head impact region, has a filling pressure which is reduced in accordance with predetermined limit values in comparison with the initial filling pressure in the airbag at the beginning of the airbag activation.

  • Patent number: 7364187
    Abstract: A ventilation device for a vehicle includes an instrument panel having a front passenger region with a front instrument panel wall region facing a windshield and a rear instrument panel wall region as a potential head-impact instrument panel wall region. An individual vent air-feeding duct, which is covered by the instrument panel, extends below the potential head-impact instrument panel wall region and extends there essentially in a direction of the transverse axis of the vehicle. A front passenger airbag module can therefore be positioned away from the potential head-impact region in a free space formed in front of the individual vent air-feeding duct. The front instrument panel wall region has, at least in some regions, air passage openings for a diffuse ventilation of the vehicle interior. Starting from the individual vent air-feeding duct, at least one branch duct is guided to a region below the air passage openings.
