  • Patent number: 12090896
    Abstract: 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.

  • Patent number: 11904733
    Abstract: 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.

  • Patent number: 10994635
    Abstract: A vehicle seat longitudinal adjuster (2) includes two guide rail pairs (P1, P2) with a first guide rail (3) and a second guide rail (4) movable with respect to the first guide rail, a motor unit (12), a gear unit (G) with a gear rotary shaft (6) connected to the first guide rail and a rotatable gear element (7). A transmission unit (11) is coupled with the gear unit and the motor unit to transmit torque to the gear rotary shaft. A gearbox (9) receives the gear unit. A support (5) receives the gearbox inside a gap (BR) formed between the guide rails and passes through a second rail opening (13) and extends out of the guide rail opening and closes the second rail opening. A vehicle seat (1), has the longitudinal adjuster for mechanically and longitudinally adjusting the vehicle seat.
