Abstract
Abstract At violent retardation, acceleration, compressing or twisting of a vehicle a transversely extending, gastight envelope by means of a first pressurized gas source is thrown backwards from a front position towards the body of the passenger so as to roll upwards over the body into a rear position, said hose during said backwards movement by means of a second pressurized gas source being inflated into a pad-like envelope of substantially larger volume catching the body and firmly securing the passenger to the seat.
