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.

A vehicle seat configured to accommodate at least two users, comprising a base, and a seating portion frame comprising at least two seating areas, a first and a second backrest which are pivotally hinged to the base, wherein the seat further comprises a connection system connecting the first backrest to the seating portion frame, configured so that the pivoting of the first backrest relative to the base causes the simultaneous movement of the seating portion frame relative to the base, and wherein the second width portion of the seating portion frame is connected to the base, by means of a connection mechanism, configured to enable movement of the seating portion frame relative to the base during the movement of the seating portion frame relative to the base.

A gearbox includes a first divided body and a second divided body, and a shaft projection is formed on and a through-hole is formed in divided surfaces of the first divided body and the second divided body. A second recess on the second divided body side includes a second arc portion formed concentrically with an axis center of a worm wheel, and an upper linear portion and a lower linear portion which extend linearly toward the first divided body side from both ends of the second arc portion. A first recess on the first divided body side includes a first linear portion which extends linearly in a direction orthogonal to an intersecting direction, and an upper arc portion and a lower arc portion which are formed continuous to both ends of the first linear portion.

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 sliding device configured for a vehicle, includes a magnetic module configured to slide on a floor of the vehicle and be fixed to the floor by a magnetic force or unfixed from the floor depending on a change in magnetic circuit due to a rotation of a first magnetic body provided in the magnetic module; a plurality of catching portions formed on the floor, spaced from one another, and provided along a movement route of the magnetic module, and fastening portions provided on the magnetic module and configured to be pressed downward by a first elastic body, the fastening portions being configured to mechanically fasten the magnetic module to the floor by being lowered and caught by the catching portions when the fastening portions are matched with the catching portions while the magnetic module moves.

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 sliding unit for a vehicle, the sliding unit may include a rail provided on the vehicle; a fixing portion formed of a material through which magnetism is flowable and provided along a direction in which the rail extends; a moving portion that is slidable along the rail; and a magnetic module provided in the moving portion, disposed toward the fixing portion, and selectively locked to the fixing portion by a magnetic path to selectively fix the moving portion to the 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 position detection apparatus for a vehicle seat which is guided using a seat rail in a floor rail of the vehicle. The seat position detection apparatus has a lock for the longitudinal setting of the seat rail and the floor rail in relation to one another, and a mechanical memory device that has a position determination unit and a position detection unit, which may be started symmetrically from both directions of the longitudinal adjustment of the vehicle seat to define a vehicle seat position.
