Problems solved by technology

However, this solution is not satisfactory, since it leads, inter alia, to a significant increase in the onboard mass corresponding to the mass of the barrier, as well as in the mass of structural reinforcements required to transmit stresses in case of intrusion intent

Abstract

The invention relates to a movable barrier (30) comprising: a panel (38) configured to at least partially close an opening delimited by a frame (34); and a plurality of strips (40), each connected to the panel (38) and each having a first and a second end (40.1, 40.2); for the strip (30), the movable barrier comprises: a first connector (46.1) configured to at least temporarily connect a first end (40.1) of the strip and a first edge (36.1) of the frame (34); a second connector (46.2) configured to at least temporarily connect a second end (40.2) of the strip (40) and a second edge (36.2) of the frame (34); at least one folding extension (58.1, 58.2) located at at least one of the first and second ends (40.1, 40.2) of the strip (40); and at least one fusible connector (64, 66) which holds the folding extension (58.1, 58.2). The subject matter of the invention also relates to an aircraft comprising at least one such movable barrier (30).

Description

technical field [0001] The present application relates to an energy-absorbing lightweight movable barrier and to an aircraft comprising at least one such movable barrier. Background technique [0002] According to an embodiment, the cockpit of the aircraft is separated from the passenger compartment by a partition having an opening closed by a safety door comprising a first side connected to the partition by a hinge system and a second side connected to the partition by a locking / unlocking system. two sides. Lock / unlock system controls are controlled from inside the cockpit. The security door, its hinge system and locking / unlocking system, and the bulkhead around the door are dimensioned to ensure stress recovery in the event of an intrusion attempt. In addition, the bulkhead and / or safety door are equipped with pressure equalization devices on both sides of the bulkhead and safety door in case of depressurization in the cockpit or passenger compartment. Finally, the disp...
