Airbag device for protecting a vehicle occupant
First Claim
1. Airbag device for protecting a vehicle occupant in case of a crash, comprisingat least one region inflatable with gas, that forms a gas cushion in an inflated state in the form of a side airbag for the vehicle occupant to be protected,at least one first material layer of the at least one inflatable region extending in front of a lateral vehicle structure of a motor vehicle in the inflated state of the airbag device, andat least one second material layer of the inflatable region that opposes the at least one first material layer in the inflated state of the airbag device,wherein at least one fastening flap is provided at the airbag device via which the airbag device can be fastened to a motor vehicle structure,wherein the at least one fastening flap is a separate element with respect to the at least one inflatable region, that is formed at least two-layered and fixed with at least each of the two layers to one of the at least one first material layer and the at least one second material layer of the at least one inflatable region via a connection line, respectively, and in that the at least two layers of the fastening flap each comprise a fastening portion,wherein each of the fastening portions comprises a free end portion folded around the connection line,wherein each of the fastening portions protrudes from the airbag device and serves for fastening the airbag device to the motor vehicle structure, andwherein the connection line runs inclined with respect to an upper edge of the inflatable region located adjacent to the at least one fastening flap or runs along a curved path.
