A rail assembly for longitudinal adjustment of a vehicle seat comprises a lower rail (2) and an upper rail (1) movable relative to the lower rail, and a movable support member (400) disposed between the lower rail (2) and the upper rail (1), wherein the lower rail (2) comprises a stopper (210) disposed at a predetermined position of the lower rail (2), and the movable support member (400) comprises a base (40) for supporting the upper rail (1) on the lower rail (2) and a coupling member (47) for releasably coupling the movable support member (400) with the upper rail (1).

The coupling member (47) can be displaced relative to the base. Movement of the movable support member (400) relative to the lower rail (2) in the longitudinal direction is stopped by the stopper (210) at the predetermined position, and displacement of the coupling member (47) relative to the base (40) is controlled by the position of the upper rail (1), for controlling a coupling and decoupling of the movable support member (400) to the upper rail (1).

An electric drive mechanism of a seat rail includes a front frame, a rear frame, a gear assembly, a lead screw and a bumper. The front frame and rear frame are separated from each other and fixed to an outer rail of a slide rail; the lead screw is spanned across the front frame and rear frame; the gear assembly driven by a driving device is fixed to an inner rail of the slide rail and engaged with the lead screw; the bumper is installed at the rear frame provide a buffering effect between the gear assembly and the rear frame, so as to prevent the production of abnormal sounds caused by colliding the gear assembly with the rear frame directly.

The invention discloses a type of seat, including the seat baseplate, the soft cushion and the underframe assembly; wherein, the said soft cushion is arranged on the said seat baseplate; the said seat baseplate is connected to the framework through the said underframe assembly; the said seat baseplate adopts integrated injection molding. The seat baseplate in the present invention adopts integrated injection molding. The soft cushion is arranged on the seat baseplate to form the complete seat. Compared with the machining method in the prior art that the backrest and the base are separately machined and then the backrest and the base are assembled with each other; the machining procedure of the seat baseplate in the present invention is simple, thus the production efficiency is improved and the production cost is reduced. The invention also discloses a type of all-terrain vehicle provided with the above seat.

An assembly including an inner component; an outer component; a tolerance ring, comprising an annular band and a plurality of projections projecting radially from the annular band, the tolerance ring being disposed between the inner component and the outer component; and a low friction layer provided radially inside or radially outside the annular band so as to enable sliding movement in an axial direction between the inner component and the outer component, wherein at least one of the inner component or outer component is profiled to transmit a radial load between the inner component and the outer component to appreciably prevent collapse of the projections.

A longitudinal adjuster (10) for a vehicle seat (1), has pairs of rails (12a, 12b) including a lower rail (14a) and an upper rail (14b) that are movable in a longitudinal direction (x) relative to one another and can be locked together by a locking device (16). An actuating device (18) has a transmission rod (22) arranged between the two locking devices. A hand grip (20), connected to the transmission rod, is provided for joint actuation of the two locking devices. The transmission rod is operatively connected to the two locking devices. A spring element (30), which applies a spring force to the actuating device toward a rest position or passive position, does not project beyond the locking device in the vertical direction (z). The spring element applies a torque to the transmission rod along the longitudinal extent thereof relative to the longitudinal direction (x).
