Abstract: A method of welding a support on a slide profile, which comprises: a) providing a support having a wall with an inner face, and providing a profile having a wall with an outer face, b) positioning the interface support with the inner face of its wall against the outer face of the wall of the profile, c) creating a welding joint between the wall of the support and the wall of the profile by moving a laser beam relative to the wall of the profile, while keeping the laser beam in a position such that it successively passes through, from an emitting source: the wall of the profile, then the wall of the support, while remaining within the material of the wall of the support.

Abstract: A vehicle seat having a pivoting function about a vertical axis, the seat comprising a pivoting assembly) with a base, a rotating ring mounted on the base by means of a hinge mechanism interposed between the base and the rotating ring, a seating portion frame connected to the rotating ring, directly or via a raising mechanism and/or longitudinal rails, the hinge mechanism allowing rotation, about a vertical main axis, of the rotating ring relative to the base and blocking any substantial movement in the other degrees of freedom, namely the other two rotations and the three translations in an orthogonal reference system.

Abstract: Reinforced section piece comprising a metal section piece and a reinforcing spacer piece, said section piece having a generally U-shaped cross-section with a base portion, said section piece comprising side wings extending perpendicularly on each side from the transverse ends of the base portion, with inner surfaces facing each other at an inside distance, the reinforcing spacer piece comprising a body having a width that is slightly less than the inner distance, and being configured to prevent the lessening of the distance between the two side wings, the reinforcing spacer piece additionally comprising protuberances projecting outwards from the body in the transverse direction, facing the curved surfaces of the male section piece.

Abstract: A set of slides for vehicle seats including two slide locks actuated by a cross-bar assembly pivotally mounted on the two slides by means of bearings. The bearings each include an indentation and the ends of the cross-bar assembly each include a tooth enabling nesting of the cross-bar assembly in the bearing parallel to the pivot axis. The tooth retains the end of the cross-bar assembly in the bearing.

Abstract: A device is for enabling a motor vehicle seat to slide. The device includes a runner, locking device, control support, control rod, and torsion spring. The locking device locks the runner having an active state and an inactive state. The control support is mounted to pivot on the moving rail between an active position in which it constrains the locking device to be in its active state and a rest position in which it allows the locking device to return to its active state. The control rod is mounted to pivot on the control support between an in-use position and a retracted position. The torsion spring tends to bring the control rod into the in-use position and tends to bring the control support into the rest position.
