Abstract
An airbag for a motor vehicle, with at least one inflatable region which is capable of being inflated by means of a gas generator and in the inflated state forms a lateral curtain for protecting a vehicle occupant. When inflated the airbag is clamped between two points on the vehicle body which are separated from each other in the longitudinal direction of the vehicle. The airbag has a separation region, which may be an opening, that is bridged by a tautening element which is capable of being inflated together with the inflatable region. When the airbag inflates the opening deforms reducing the length of the opening in the longitudinal direction of the vehicle.
Claims27
An airbag for a motor vehicle comprising:
- an inflatable region configured to be inflated so that when inflated the region forms a lateral curtain for protecting a vehicle occupant;
- a separation region bridged by a tautening element which is capable of being inflated together with the inflatable region so that when the tautening element inflates the separation region is deformed thereby reducing the length of the region in the longitudinal direction of the vehicle;
- wherein the airbag is clamped between two points on the vehicle body which are separated from one another in the longitudinal direction of the vehicle;
- and
- wherein the tautening element is fastened to the airbag on two sides of the separation region.
An airbag a motor vehicle comprising:
- two inflatable regions configured to be inflated so that when inflated the regions form a lateral curtain for protecting a vehicle occupant;
- an opening bridged by a tautening element which is capable of being inflated together with the inflatable regions so that when the tautening element inflates the opening is deformed thereby reducing the length of the regions in the longitudinal direction of the vehicle;
- wherein the airbag is clamped between two points on the vehicle body which are separated from one another in the longitudinal direction of the vehicle;
- wherein the opening is provided in a portion of the airbag which extends between the two inflatable regions of the airbag.
