1. A ventral parachute sling for an ejector seat, which on the one hand comprises a body (1) made up of a ventral base (12) and of a ring (13) with slots (4a, 4b) to receive operating lugs (5a and 5b), and sockets (32a and 32b) to receive attachment rings (B1 and B2 ) and on the other hand an operating knob (2) being able to be turned in relation to the body (1), and which is characterized in that it furthermore comprises, within the totality of the body (1) and of the knob (2) : - heads (15a and 15b) projecting from the base (12) opposite to the sockets (32a and 32b) in order to arrest the holes (b3 and b4 ) produced conventionally in the rings (B1 and B2 ), - a rotary member (18) with peripheral teeth (19) having inclined flanks (191 ) constituting ramps, the tips (242 ) of the teeth being directed towards the opposite side of the base (12), - means transmitting the rotation of the knob (2) the rotary member (18), - an ejecting member (22) with rollers (20) running on the said flanks constituting the ramps in such a manner that the rotation of the member (18) with the teeth causes axial translation of the ejecting member, the said ejecting member (22) having a grooves (28a and 28b) adapted to cooperate with the rings (B1 and B2 ) in order to move them away from the base (12) at the same time as they do, - elastic means (23) urging the rollers (20) onto the ramps of the teeth, and - an elastic ring (31) in order to eject the rings (B1 and B2 ) out of their sockets (32a and 32b) when the ejecting member (22) assumes a position removed from the base (12). |
