Abstract: The vehicle seat runner has a first runner element receiving a vehicle seat element, and a complementary runner element fastened to the vehicle. A first fin wall and a second fin wall that are mutually parallel and that are spaced apart from each other are connected together via a base wall. Each fin wall has an inside face, the inside faces of the two fin walls facing each other. The inside faces are connected to each other in an additional connection region situated under the base wall.

Abstract: A slider for a motor vehicle seat including a stationary profile section extending in a longitudinal direction and comprising a substantially planar base plate and at least one side shoulder, said base plate having a substantially constant width and including an attachment area for receiving a head of a fastening screw, wherein the stationary profile section has a local deformation increasing the width of the base plate and narrowing the shoulder to the extent that the raceway of the stationary profile section is blocked; a movable profile section; roller elements rolling along a raceway extending longitudinally on the shoulder of the stationary profile section and retained in position relative to each other by cage.

Abstract: The invention concerns a rail comprising a fixed profiled section and a mobile profiled section sliding relative to the fixed profiled section. The body has a linking portion wherein the body is shaped like a plate having first and second opposite lateral surfaces, and an edge linking said first and second surfaces. A first profiled section comprises a groove. The linking portion is tightly fitted in the groove. The plate is attached to the first profiled section.

Abstract: Hinge mechanism comprising first and second frames connected together by an adjustment device comprising a first set of gear teeth integral with the first frame and a first mobile toothed element engaging with the first set of gear teeth A second toothed element, mounted mobile on the second frame, engages with an additional set of gear teeth integral with the first frame.

Abstract: The runner comprises a mechanical locking system and a memorization system, comprising: a locking bar, a locking device that is movable between a normal position and a locking position in which it cooperates with the locking bar, an electromagnetic actuator that moves the locking device to its locking position when it receives a command from a control device.

Abstract: Method for manufacturing a hinge mechanism including: a movable flange and a stationary flange; holding means for ensuring holding of the stationary and movable flanges. The method includes the following steps: the holding means are applied to the stationary flange, a portion of the holding means being in radial contact with an outside portion of the movable flange, the holding means are fastened to the stationary flange, at the same time, a clamping pressure is applied to the holding means, this clamping pressure being directed radially in order to apply a radial pressure of the holding means on the movable flange, so as to take up the play in the hinge.

Abstract: Vehicle seat articulation mechanism intended to connect two elements belonging to the seat, the articulation mechanism comprising first and second rigid cheek plates extending in parallel planes and intended to be attached respectively to the two seat elements, and an adjustment mechanism connecting the first and second cheek plates and suitable for allowing a relative angular adjustment between the said cheek plates. The first cheek plate is trapped against the second cheek plate by at least one rigid annular gusset which is welded against the inner face of the second cheek plate.

Abstract: A runner for a vehicle seat, the runner being of the type comprising a male rail (7) and a female rail (6) which define between them at least a first compartment (8) in which rolling bearing elements are disposed to enable said male and female rails to move relative to each other along a longitudinal axis. The runner further comprises at least one shoe (10) received in the first compartment (8) and mounted to slide relative to one of the rails, namely the male rail or the female rail, the shoe comprising at least a first rigid portion (11) having a shape substantially complementary to the shape of the first compartment in order to offer contact zones for contact with the male rail and with the female rail when the runner is subjected to deformation in a first direction.

Abstract: A runner for a motor vehicle seat, said runner comprising firstly first and second rails mounted to slide relative to each other in a longitudinal direction, and secondly a locking mechanism including an additional latch mounted substantially to pivot on a main latch about a second pivot axis, the additional latch being interposed between the main latch and a control member so that, when the control member moves from the locking position to the unlocking position, firstly the additional catch is pivoted about the second pivot axis, and secondly the additional latch and the main latch are pivoted about the first pivot axis.

Abstract: A track assembly for a motor vehicle seat, the track assembly comprising a male track and a female track. An internal space extends longitudinally between the male track and the female track. The cross-section of the internal space varies along the longitudinal axis of the track assembly. A seat equipped with such a track assembly.
