A seat includes a base frame, seat frame, and footrest, the seat frame retained on a sliding member and pivotable about a first axis. The sliding member is displaceably guided between first and second positions in a guiding profile. The footrest is articulated to the seat frame by a rod mechanism to be adjusted between a folded-in and folded-out position. A drive for displacing the sliding member and adjusting the footrest is provided between the base frame and rod mechanism. A dual-arm lever arm having a first end, second end, and central region is rotatably supported on the sliding member in the central region and is connected with the first end to the rod mechanism and the second end to the seat frame. Movement of the footrest between the folded-in and folded-out position causes a pivot movement of the seat frame about the first axis between basic and inclined positions.
