Abstract: The device includes an actuation system, normally housed in a sleeping or rest position within a space which is inner with respect to a vehicle rear window, and that can be actuated, following a collision or accident involving the vehicle, a closure element for the space housing the actuation system, provided between the latter and the rear window. The closure element has a pin for breaking the rear window. The actuation system, after its activation, strikes the closure element, making it move, along with the at least one pin, toward said rear window. The actuation system and the closure element travel with the same speed until the end of the stroke of the actuation system, the stroke ending before the actuation system contacts the rear window, the closure element, along with the at least one pin, further prosecuting its stroke until striking the rear window, breaking the rear window.

Abstract: The invention relates to a device for breaking rear window (1) of a vehicle, said device being comprising an actuation system (3), normally housed in a sleeping or rest position within a space which is inner with respect to said vehicle rear window (1), and that can be actuated, following a collision or accident involving said vehicle, a closure element (4) for said space housing said actuation system (3), provided between the latter and the rear window (1), said closure element (4) having a pin (5) for breaking the rear window (1), said actuation system (3), after its activation, striking said closure element (4), making it moving, along with said at least one pin (5), toward said rear window (1), said actuation system (3) and said closure element (4) travelling with the same speed until the end of the stroke of the actuation system (3), said stroke ending before the actuation system contacts the rear window (1), said closure element (4), along with said at least one pin (5), further prosecuting its stroke u
