An automobile seat includes a seat back that is mounted on the seat body that pivots forward about a pivot axis, and two parallel seat rails on which the automobile seat is connected with the chassis so that it may be displaced longitudinally. Each of the seat rails includes base rails attached to the chassis and a slide rail that may be displaced longitudinally with respect to the base rail. The slide rail may be displaced via an electrical spindle drive that includes a drive motor, a drive spindle, and a spindle nut mounted thereon. The spindle nut is formed in two parts along the rotational axis of the drive spindle, and its parts may be moved into and out of engagement with the drive spindle via an actuation device. By means of the separation of the two parts of the spindle nut via the actuation device, they are not engaged, so that the slide rail is free to slide along the base rail.
