Abstract

The invention relates to a restraint device, in particular for a motor vehicle, for reducing an abrupt sideward movement of an occupant in the case of an impact with an airbag which is inflatable by means of a gas generator when an accident situation occurs. It is provided that the airbag has at least one side chamber and one shoulder chamber which are connected together, wherein in the inflated state of the airbag the side chamber and the shoulder chamber form different main extension planes which run at an angle to one another. An anchoring strap is fastened at one end to the shoulder chamber and at the other end to the vehicle seat. The shoulder chamber comprises two regions which transition into one another and which together form a reverse U-shape, the base thereof in the inflated state of the shoulder chamber forming the upper end thereof.
