Abstract

An airbag arrangement for a motor vehicle includes an airbag deployable in a direction to protect a vehicle occupant and an arrangement for limiting the unfolding impulse of the airbag upon an obstacle placed in a deployment path of the airbag to reduce the unfolding impulse transferred to the obstacle. The limitation arrangement, which can be, for example, a sheath, aperture in the airbag, can respond to the resistance of the occupant located in the deployment path, which is outside a normal seating position, or respond to a lack of resistance from the passenger. As the limitation arrangement limits the unfolding impulse of the airbag, it reduces the maximum unfolding impulse transferable to the occupant located outside the normal seating, in the deploying path.
