  • Patent number: 8474910
    Abstract: A vehicle seat includes a base (9) which includes at least one front foot (11). A seat (3) is connected in an articulated manner to the front foot by at least one front leg (13). At least one rear foot (21) is locked to the base (9) in at least one use position. At least one coupling (42) is provided between the seat and the rear foot. At least one coupler (30) is provided between the backrest and the coupling or the seat. The seat may be transferred from the use position into a boarding position as, after unlocking the rear foot, the seat pivots upwards and the backrest carries out a forward shifting movement by means of the rear foot. The seat may also be transferred from the use position into a flat-floor position, by the backrest pivoting forward and the seat being lowered by the coupler.
