A longitudinal adjustment mechanism for a vehicle seat may have a first rail and a second rail. The rails may engage about one another to form an inner channel. A spindle nut may be connected to the second rail and a spindle operationally connected to the spindle nut may be arranged in the inner channel. On one end of the first rail, a transmission may be driven by a motor, which may interact with the spindle. The spindle may be screwed into an internal thread of a worm gear of the transmission, and the spindle may be conjointly connected by a fixing element to the worm gear. The fixing element may be arranged coaxially to a spindle axle of the spindle and may be pressed between a front end portion of the spindle and the worm gear. A vehicle seat having the longitudinal adjustment mechanism is also provided.

Longitudinal adjustment mechanism, vehicle seat

A longitudinal adjuster for a vehicle seat may have at least one pair of rails which is formed from a first rail and a second rail. A spindle nut may be connected to the second rail and a spindle operatively connected to the spindle nut are located in the inner channel. A spindle gear, which can be driven a motor and interacts with the spindle, may be located at one end of the first rail. The spindle nut may be fixed to the second rail so that the spindle nut has a degree of freedom of at least one. The spindle nut may be fixedly connected to the second rail by a fixing device. A projection may be provided between a base body of the spindle nut and the second rail. The invention also relates to a vehicle seat with the longitudinal adjuster.

Longitudinal adjuster and vehicle seat

A longitudinal adjuster for a motor vehicle seat may have a first rail, a second rail, a spindle, and a gear. The gear may be fastened to the second rail by a substantially U-shaped gear holder, and the gear holder may have at least two limbs arranged opposite one another in the longitudinal direction. The gear holder may have at least one recess in a base connecting the two limbs, and a gear housing surrounding the gear projects at least in sections into the at least one recess. A motor vehicle seat may have the longitudinal adjuster for adjusting a seat longitudinal position.

Longitudinal adjuster for a vehicle seat, and vehicle seat

An adjusting device for a vehicle seat may have a first adjustable assembly, a second adjustable assembly, and an electric motor. The electric motor may be operatively connected both to an adjustment gearing of the first adjustable assembly as well as to an adjustment gearing of the second adjustable assembly by at least one output shaft. A motor support may be provided which receives the electric motor, and the motor support may be secured to the two adjustable assemblies via a respective adapter. The motor support may have a metal material as a single piece. The adapters may be made of a non-metal material. A method for assembling the adjusting device may include first securing the adapters to the respective paired adjustable assembly. The motor support may be connected to the adapters in an additional step.
