Abstract
Abstract A motor vehicle seat has a base element which can be fastened in the motor vehicle, a seat element which is disposed on the base element, and a backrest element which is disposed on the seat element. The seat can be adjusted between a locked position and an unlocked position. In the locked position, the seat element and the backrest element can be used for normal sitting. In the unlocked position, the seat element and/or the backrest element are adjusted in the vehicle to the front with respect to the driving direction far enough so that a space arranged behind the seat with respect to the driving direction is accessible for loading and unloading. For adjustment between the locked position and the unlocked position, the seat element is swivellably disposed on the base element and/or the backrest element is swivellably disposed on the seat element. In order to reduce stress on the seat during a restoring movement from the unlocked position to the locked position, damper devices are provided in order to counteract the restoring movement at least during its end phase.
