A return device for retracting an attachment device of an aircraft. The attachment device is movable between a retracted storage position and a deployed working position, the return device tending to place the attachment device in the retracted storage position in the absence of an external load, while allowing the attachment device to move towards the deployed working position in the presence of an external load. The return device comprises resilient return means for exerting a traction return force on the attachment device and automatically bringing the attachment device into the retracted storage position; a force-reduction member for reducing the traction return force exerted by the resilient return means on the attachment device; and a line element having a first free end secured to the attachment device and a second free end secured to the force-reduction member.

Return device for retracting a movable attachment device, and an aircraft fitted with such a return device

A fastener device () provided with attachment means () for attaching an external load () and with fastener means () provided with a support beam () and with anchor means () for anchoring said support beam (). A first mechanical coupling () connects said support beam () to the anchor means () so as to enable the support beam () to pivot about a first pivot axis (AX). In addition, coupling means () are hinged to the support beam () so as to make pivoting possible about a second pivot axis (AX), the attachment means () being hinged to the coupling means () to make pivoting possible about a third pivot axis (AX). This fastener device () includes automatic folding means ().
