Abstract

An occupant restraint device for a vehicle, including a side cheek protruding from a backrest of a vehicle seat. A supporting structure of the vehicle has an outer side facing an exterior space of the vehicle and an inner side facing away from the exterior space of the vehicle and facing the outer side of the side cheek. An airbag arranged in the vehicle seat is supported on the inner side of the supporting structure and exerts an opposing force on the outer side of the side cheek when the airbag is inflated, the force being directed onto the outer side of the side cheek. A pre-crash detection device for identifying an imminent application of force on the outer side of the supporting structure from the exterior space, the pre-crash detection device activating an expansion of the side cheek in an expansion direction along the supporting structure.
