Safety device for the protection of vehicle occupants
First Claim
1. A safety device for the protection of vehicle occupants, comprising a curtain airbag located in the area of the roof frame along the side of the vehicle interior, wherein the airbag is rolled up in an undeployed state and is unrolled in a deployed state in case of a potential accident and which can be filled with a gas, the curtain airbag forming an upper edge, and wherein the curtain airbag when in the undeployed state is rolled around the upper edge around a shaft into a roll and that fixing elements support the upper edge such that the airbag is rotatable between the undeployed state and the deployed state in which the airbag is unrolled, andunrolling means for acting on a lower edge of the curtain airbag in case of a potential accident for unrolling the airbag from the undeployed state to the deployed state and causing the shaft to rotate.

Abstract
A safety device for protection of vehicle occupants is described. The safety device exhibits a curtain airbag (10) located in the area of the roof frame, with an upper edge (10a), which is rolled up in quiescent state and unrolled in the case of an accident. The curtain airbag can be filled with gas. In order to enable the safety device to be used reversibly, the curtain airbag (10) is rolled up to roll around its upper edge (10a) when in quiescent state, and the upper edge is held by fixing elements in a manner which the airbag is rotatable.
