Snap-action connecting device and its application in particular to vehicle-seat-frames.

摘要

The device for joining together the male and female parts is characterised in that the female part (11) is in the form of a hollow tube end piece deformed in order to give it an inner cross-section (110) approximately in the shape of a bone with a median bridge joining two end protuberances, a hole (111) emerging in this median bridge, in that the male part (12) is in the form of a tail with an approximately rectangular external section (120) intended to be engaged in this end piece, an orifice (121) passing through this tail and being intended to be brought into correspondence with this hole (111), and in that an elastic L-shaped clip (13) with a long branch (131) and a short branch (132) is fixed to the median bridge of the female part (11) by its long branch (131) so that its short branch (132) can normally engage in the hole (111) and can also penetrate into the orifice (121). Application to seats with the seat cushion overmoulded on the frame.
