Title:
A BUMPER AIRBAG WITH MULTIPLE CHAMBERS
Document Type and Number:
WIPO Patent Application WO2002055337
Kind Code:
A9
Abstract:
A multi-chambered bumper airbag for deployment from the bumper of a vehicle in the event of a collision with another vehicle is provided. The airbag comprises a main inflatable portion that, when inflated, absorbs the energy from contact with a structural member of the struck vehicle. The airbag also has one or more secondary inflatable portion concentric with the main inflatable portion. Because the secondary inflatable portions have a lower gas pressure than the main inflatable portion, they are used to cushion the occupant of the struck vehicle should the occupants' head and neck be forced out of the window of the struck vehicle.
