ABSTRACT:
This electromechanical device with a manual emergency control for opening the door of a safety outfit box on board an aircraft comprises in said box a spring-loaded piston responsive to an electromagnet and having a head shaped to control the movements of registering locking members into or out from their locking position in which they engage a retaining hook engageable in turn with a cross member of a strap carried by the door. Said locking members may consist of balls or small ball-bearings engageable in corresponding holes formed in a sleeve concentric to said piston. Manual control means are provided for actuating said piston from the outside and thus opening the door in case of emergency.
