ABSTRACT:
A rope or cord system on a helicopter comprises a beam (18) fixed to the helicopter floor or roof in the vicinity of an opening (12). Ropes or cords (16) for the lowering to the ground of intervention personnel are attached to bolts (20) by rings (22). The operation of a handle (24) makes it possible to simultaneously and instantaneously release or jettison all the ropes (16) by pivoting a clasp (32) into each of the bolts in opposition to a spring (36). For this purpose the handle (24) simultaneously operates the pivoting latches (42), which cooperate with the clasps by complimentary cam surfaces (40, 46).
