An occupant restraint device for a motor vehicle includes a supporting structure of the motor vehicle. The supporting structure includes an outer side facing an exterior of the vehicle and an inner side facing an interior of the vehicle. A vehicle seat includes an outer side facing the inner side of the supporting structure. A receptacle for an airbag is arranged on the outer side of the motor vehicle seat. An openable region is included on the receptacle such that the airbag can be deployed into the interior of the vehicle. A pre-crash detection device identifies an imminent application of force on the outer side of the supporting structure. The pre-crash detection device triggers a shifting of the receptacle from an inoperative position into an operative position along a direction of movement between the outer side of the vehicle seat and the inner side of the supporting structure.
