The present invention provides a device for controlling the movement of a
vehicle closure element, the device comprising, interposed between a
vehicle structure and a closure element, firstly a driver element that
can be activated on command, constituted by a pyrotechnic actuator, and
secondly mechanical connection means suitable for allowing a driving
connection between the pyrotechnic actuator and the closure element when
the pyrotechnic actuator is activated, while also allowing the closure
element to move freely relative to the pyrotechnic actuator when the
closure element is moved over a stroke greater than that enabling said
driving connection.
