Instantly lockable slideway

Claim 1

A slideway, in particular for a motor vehicle seat, the slideway comprising a first section member and a second section member that are slidable relative to each other in a longitudinal direction, and a locking mechanism for locking the first section member longitudinally relative to the second section member in a plurality of locking positions, said locking mechanism having at least two blades designed, in a locking position, to engage independently of one another with notches of a certain width that are uniformly distributed along at least one rail secured to the second section member, said blades being simultaneously disengageable from said notches by unlocking means, wherein the first section member and the second section member are respective channel section members each having a web and two flanges, the two channel sections being upsidedown relative to each other to define an inside volume, said first section member sliding longitudinally between said flanges of the second section member, wherein each of said at least two blades comprises: a first end portion fixed on the first section member in said inside volume; and a running portion provided with locking teeth of a width that is substantially equal to the width of the notches, wherein said at least two blades are disposed relative to one another in such a manner as to guarantee, in most relative positions of the first and second section members, that at least one of said blades engages in the notches of said at least one rail, wherein said blades are elastically bendable towards one of the two webs of said section members, and wherein the unlocking means are secured to the first section member and cause said at least two blades to bend elastically, thereby disengaging said locking teeth from said notches.
