Abstract

Abstract A release device for releasing an inflatable element for protecting a vehicle against impact, which element, once inflated, presents a general shape that fits closely over the region of the vehicle to be protected, said inflatable element being held, in a folded state, in a compartment that includes a wall that is connected in sealed manner to an edge of an opening of said inflatable element, wherein, facing said opening, said wall includes gas release means that are protected during inflation of the inflatable element by a closure flap controlled by actuator means that remove said closure flap once the inflatable element is deployed.
