As yet great intrusion of vehicle side into a passenger compartment of motor - vehicle in side collisions causes injury- and whiplash-related deaths linked to collapse of the totally deformed vehicle side and incapability of side airbags to absorb great lateral energy and prevent the intrusion thereof. In any side collision a side airbag-substitute removes a passenger, sitting on the seat rotating about an inboard and/or outboard floor rail, from an injury-prone area to a vehicle-centre during which lateral energy is lowered by work of fracture of sites of predetermined fracture of the outboard floor rail and the removal of the passenger and seat and the remaining energy is absorbed by at least one energy absorber, which in conjunction with a side impact member, longitudinally arranged between the vehicle side and seat, withstands the intrusion thereof, and transmitted into the vehicle floor. In the second feature of invention, whiplash-related oscillations are dampen ed and lateral energy is substantially absorbed by the energy absorber. In the third feature, the energy absorber is designed with a progressive spring rate to achieve a larger working area and minimize the depth of intrusion. In the fourth feature, in order to save costs and avoid false deployments a front airbag is convertedinto a safety airbag which is inflated in the event of front and/or side collision. Owing to the features to withstand the intrusion thereof and to remove the passeng er to the vehicle- centre in side collisions the deployment time can be prolonged. In the fifth feature, in order to save costs all the transversely-assembled energy absorbers of the front and successive seats are connected to a single longitudinally-assemble d energy absorber.
