Abstract
The invention relates to a restraint system for a vehicle occupant (26) in a motor vehicle, comprising a front airbag (28), in particular a driver's airbag, and a side airbag (14), in particular a curtain airbag. In the inflated state, the side airbag (14) is arranged and shaped in such a way that, in the event of a glancing impact of the vehicle occupant (26) on the front airbag (28), the side airbag (14) provides no significant support for the front airbag (28) in the vehicle transverse direction (y) in a front open region (20), relative to the direction of travel (x) of the vehicle, of the vehicle side below the A-pillar (12).
Claims13
A restraint system for a vehicle occupant in a motor vehicle, the restraint system comprising:
- a driver front airbag mounted on a steering wheel of the vehicle and configured to inflate between the steering wheel and the vehicle occupant, and
- a curtain airbag configured to inflate from a roof frame member to an inflated state in which the curtain airbag is positioned between a vehicle door and the occupant, the curtain airbag being configured to cover a window opening and a portion of the door below the window opening, and to extend from a B-pillar of the vehicle to an A-pillar of the vehicle and at least partially along the A-pillar,
- wherein the driver front airbag is configured to tilt relative to the steering wheel and move obliquely forward and laterally into a free area on the door in response to an angular impact of a head of the occupant with the driver front airbag, the free area extending from adjacent the driver front airbag forward of a steering wheel rim of the steering wheel,
- wherein the curtain airbag comprises a portion configured to provide minimal interaction with the driver front airbag in order to allow the driver front airbag to tilt relative to the steering wheel and move obliquely into the free area without restraint.
A restraint system for a vehicle occupant in a motor vehicle, the restraint system comprising:
- a driver front airbag mounted on a steering wheel of the vehicle and configured to inflate between the steering wheel and the vehicle occupant, and
- a curtain airbag configured to inflate from a roof frame member to an inflated state in which the curtain airbag is positioned between a vehicle door and the occupant, the curtain airbag being configured to cover a window opening and a portion of the door below the window opening, and to extend from a B-pillar of the vehicle to an A-pillar of the vehicle and at least partially along the A-pillar,
- wherein the driver front airbag is configured to move obliquely forward and laterally toward the door in response to an angular impact of the occupant with the driver front airbag;
- wherein the curtain airbag comprises a portion configured to leave uncovered an area on the door that receives the driver front airbag when the driver front airbag moves obliquely forward and laterally in response to the angular impact of the occupant so that the curtain airbag interacts minimally with the obliquely moving driver front airbag.
