Patent ID: 7438511

Claim:
A device for mounting a seat on a mounting rail, said rail comprising a back wall, two lateral walls and two wings that delimit a groove in the shape of an inverted T, said wings forming notches at regular intervals that define widened and narrowed sections of a passage in between edges of the wings, said device comprising: a base, a sliding nut, a control lever, and a locking means; wherein the base comprises a band operable for linking to the seat, the groove adapted to receive a guide rail, and a longitudinal blocking piston operably insertable into one of said widened sections of the mounting rail such that the piston is restrained longitudinally from entering one of said narrowed sections, said base being releasably secured to said mounting rail; the sliding nut comprises protrusions that form lateral lips, and the guide rail insertable into said groove of the base, said sliding nut being arranged so as to slide in relation to said base when said base is releasably secured to said mounting rail with said protrusions placed in said mounting rail, in between an installation position and a blocked position, such that: in said installation position, when the piston of the base is in one of said widened sections, the lips of the sliding nut can be inserted in one of such widened sections, and in said blocked position, the lips of the sliding nut are held by said wings in one of said narrowed sections; the control lever is hinged to said base and said sliding nut, so as to cause said lever to move in between an open position and a closed position in relation to said installation position and said blocked position of the sliding nut; and the locking means is operable to lock said lever in its closed position.
