A translation assembly for a vehicle includes a rail assembly that defines a first channel, a second channel, and a central member that extends between the first and second channels. A carriage assembly couples to the rail assembly. The carriage assembly is movable relative to the rail assembly. The carriage assembly includes a first rail engagement structure that extends into the rail assembly and is received within the first channel; a second rail engagement structure that extends into the rail assembly and is received within the second channel; and a carriage housing that is coupled to the first and second rail engagement structures. The carriage housing extends between the first and second rail engagement structures. The carriages assembly also includes one or more drive assemblies that engage with a top surface of the central member of the rail assembly.

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.

A seat track assembly provides forward and rearward movement of a seat assembly. A latch mechanism allows movement of a movable track between a plurality of positions. A memory mechanism with a memory plate and a memory tab are operable between a home position in which the memory tab is disposed in a recess of the moveable track, and a memory position in which the memory plate is coupled with a plurality of angled teeth to define a selected position. Actuation of the memory mechanism to the memory position unlocks the latch mechanism to allow movement of the movable track in a first direction away from the selected position to an easy-entry position. Movement of the movable track in a second direction from the easy-entry position stops the movable track at the selected position, allowing the latch mechanism to lock and the memory mechanism to return to the home position.

A support assembly may be configured for connections with, adjustment along, and removal from a track assembly. The support assembly may include a support member and/or an electrical connector. The electrical connector may be adjustably connected to the support member and adjustable to a first position and a second position relative to the support member. The electrical connector may include a first contact configured to engage a first conductor of said track assembly. The first contact may be engageable with said first conductor when the electrical connector is in the first position. The electrical connector may be configured such that the first contact is disposed at a distance from said first conductor when the electrical connector is in the second position. The first contact may be movably connected to the electrical connector such that the first contact is movable relative to the electrical connector and the support member.

In order to prevent distortion of slide rails caused by an urging force generated by an urging member in a vehicle tumble seat, a vehicle seat is capable of taking a stowed position in which a seat back is folded onto a seat cushion and the seat cushion together with the folded seat back is rotatably lifted away from a floor, and the vehicle seat is configured to include a support member coupled to the floor; a rotating member rotatably supported by the support member via a support shaft extending in a right-left direction; a lower rail extending in a front-rear direction and coupled at an end to the rotating member so as to be extend literally offset relative to the support shaft; an upper rail slidably supported by the lower rail and coupled to the seat cushion; a coupling device provided at a second end of the lower rail on a side toward the support shaft and capable of selectably connecting to the floor; and an urging device extending the front-rear direction and having one end coupled to the support member and a second end coupled to the lower rail on the side toward the support shaft side, wherein the urging device is configured to be expandable and contractible in a longitudinal direction thereof so as to urge the seat cushion in such a direction as to rotate about the support shaft away from the floor.

A seat rail assembly capable of stably holding a position of one or more vehicle seats relative to the vehicle floor. The seat rail assembly includes an upper rail on which the seat is provided and a lower rail which is mounted to the vehicle floor. The upper rail is slidably provided within the lower rail, and incorporates an engagement assembly with a dual wedge engagement assembly to ensure constant contact between the lower and upper rails. A gearbox configured to remove lash may be provided on the upper rail for moving the upper rail relative to the lower rail.

A lock assembly for a vehicle seat includes a lever that has a body and a retention tab that extends from the body, a biasing member that is operably coupled to the body of the lever, an engagement member that is proximate to the lever, and an inertia member that has a weighted head and a retention hook. The inertia member is operable between a first position and a second position.

A seat slide device that can adjust sliding resistance of sliding of an upper rail with respect to a lower rail in an unlock state is provided. The seat slide device is provided in a vehicle and includes a lower rail fixed to a floor of a vehicle, an upper rail fixed to a seat of the vehicle and supported to be capable of sliding with respect to the lower rail, a lock mechanism configured to switch a lock state in which movement of the upper rail is restricted and an unlock state in which the movement of the upper rail is allowed, and an adjusting mechanism configured to adjust sliding resistance of sliding of the upper rail with respect to the lower rail in the unlock state.

An embodiment rail device includes an upper rail, a first bearing support on the upper rail, a lower rail, a bearing connection end on the lower rail and inserted into the first bearing support, a vertically elongated bearing contact adjustment hole on the lower rail, an upper bearing rotatably connected to the bearing connection end and in close contact with a floor of the first bearing support, a lower plate including a fastening groove that receives a lower end of the lower rail, a bearing shaft mounting hole on a wall surface portion of the fastening groove and matched with the bearing contact adjustment hole, a second bearing support outside the fastening groove and having an opened upper portion, a lower bearing rotatably disposed within the second bearing support, and a bearing shaft fastened to the bearing shaft mounting hole and the bearing contact adjustment hole by a screw.

A slide rail for a motor vehicle seat, comprises a first profile, a second profile and an interior space which extends in a longitudinal direction, the interior space extending between the first profile and the second profile, the second profile being movable relative to the first profile, rolling elements which are arranged in the interior space and configured to guide the movement of the second profile relative to the first profile in the longitudinal direction, and a runner which is arranged in the interior space and holds the second profile relative to the first profile in a support direction perpendicular to the longitudinal direction, wherein the runner is selectively connected to the first profile or to the second profile.
