Abstract: A cover for covering a vehicle seat back is designed to be put into place on the seat back by being turned progressively the rightway out. The cover includes vertical fixing strips designed to penetrate into vertical slots formed in the front face of the foam padding of the seat back to be fixed to fastening members disposed inside the vertical slots. Each fixing strip is a sheet of flexible material having a longitudinal edge sewn to the inside of the cover and a free longitudinal edge that penetrates into the slot to be fixed to the fastening members therein. The free edge is reinforced by an inextensible cord sewn along the free edge and extending without folds along the edge.

Abstract: The device serves to fasten the edge (7) of the cover (6) of the cushion constituting a seat back (5) to the outer flange of a channel (4) that is open towards the rear and that is provided at the edge of a plate (3) constituting framework for said cushion, the fastening device comprising a J-section member (9) attached to the edge of said cover. Said flange is firstly extended outwardly by a lateral gutter (10, 11) that is open in the opposite direction to the channel, and secondly it has a series of holes (12) punched out therein so as to form a corresponding number of tabs (13) extending parallel to the general plane of the plate, and towards the inside of the channel.
