Slide rail for vehicle seat and vehicle seat comprising such a slide rail

A slide rail for a vehicle seat, comprising:

• a first slide member and a second slide member which are mounted so as to slide relative to one another along a longitudinal direction, the first slide member comprising holes aligned along the longitudinal direction,
• a mechanical lock mounted on the second slide member and comprising several locking members, each locking member being independently movable between an unlocked position where the locking member does not interfere with the holes of the first slide member, and a locked position where the locking member enters a hole of the first slide member to immobilize the first slide member and second slide member relative to one another, the locking members being resiliently biased towards the locking position and being either held in unlocked position when the lock is in an unlocking position, or freely movable to the locked position when the lock is in a locking position, the locking members and the holes of the first slide member being arranged so that several locking members can enter the holes of the first slide member when the lock is in the locking position,
• wherein the lock is mounted on the second slide member so as to provide translational clearance between the lock and the second slide member at least in one way along the longitudinal direction, said translational clearance allowing a limited travel of the second slide member in the longitudinal direction when at least one of the locking members is in the locking position.
