Abstract
The slideway comprises first and second section members that are slidable relative to each other, together with a locking mechanism for locking the seat longitudinally, which mechanism comprises four resiliently flexible blades each including teeth suitable for co-operating, in a locking position, with notches formed in the second section member. The first section member has unlocking means suitable for acting simultaneously on all four blades, causing them to bend elastically so that the teeth of all of the blades are disengaged from the notches. The blades are disposed relative to each other in such a manner that in most positions of the first section member relative to the second section member, at least one of the blades meshes with the notches.
