Manually operable locking device for a seat slide, and compensation for horizontal play, cooperating with one of the vertical legs of the moveable upper rail of a slide fitted with a rack for engaging the locking device which has teeth (13) on a comb (12) which have a square section for cooperating with the rounded profile (5a, 5b) of the base of the teeth (5) of the rack (4), characterised in that: a) a circular cutout peg (6) formed by a stamped part joined to the lateral surface of a locking device (10) acts as a pivot pin for this locking device (10) passing through an oval hole (11) formed on one (3d) of the vertical legs of the upper moveable rail (3), this locking device being guided at the front by a cleft (7) in the leg of this same upper rail and then having at its top part a horizontal triangular leg (14) pierced by a hole (15) receiving one (19a) of the ends of a leaf spring (19) working in a flexed condition while the other end rests in a cleft (8) in the rear part of the leg (3d) of the moveable rail (3) in order that the comb (12) of the locking device (10) passes into a rack (4) carried by one of the legs (1a) of the non-moving rail (1) of the slide, the comb (12) being locked in the rack (4) by the tilting of the locking device (10) about the cutout peg (6) accommodated in the oval hole (11) under the action of the leaf spring (19), b) the leaf spring (19) exerts through its free end or point (19a) a turning moment on the locking device by bending through the hole (15) formed in the leg (14) of this locking device to cause the circular cutout peg (6) to interact with the points (11a, 11b) of the oval hole (11), the other end of the leaf spring (19) being supported in the rear cleft (8) formed on the side face (3d) of the upper rail (3). <IMAGE> |
