Abstract
A protective device for a motor vehicle comprising an airbag with an inflatable section for protecting an occupant in the passenger compartment. The inflatable section of the airbag is formed by two woven fabric plies that are joined to one another along a peripheral edge. The airbag forms a curtain next to a window pane so that one woven fabric ply faces the window pane and the other woven fabric ply faces the passenger compartment. The woven fabric plies are additionally joined to one another at points inside of the edge. The protective device also includes a gas generator for inflating the airbag by introducing a gas stream into the inflatable section. The points on which the woven fabric plies are additionally joined to one another, are arranged and configured so that a portion of the introduced gas stream is guided in a helical pattern.
