- a backrest connected for rotation to the seat portion;
a frame supporting the seat portion;
first adjusting means coupled to the frame for adjusting the position of the seat portion in relation to the vehicle; and
second adjusting means coupled to the frame for adjusting the angular position of the backrest in relation to the seat portion;
the first adjusting means comprising first guide means for attachment to the vehicle and for longitudinally guiding the frame and shift means coupled to the seat portion and first guide means for vertically adjusting the position of the seat portion in relation to the first guide means in a lift direction;
characterized by the frame comprising two spaced sides, each side comprising a bottom portion connected in sliding engagement to the first guide means, and a top portion connected to the seat portion;
said shift means comprising, for each said side, a vertical guide and slide assembly, the guide and slide assembly being coupled to and interposed between said bottom and top portions, and first and second actuating devices each coupled to the top and bottom portions and to a corresponding slide assembly on a side for imparting to the top portion rocking movements relative to the bottom portion for vertically lifting the top portion relative to the bottom portion in said lift direction, said rocking movements being directed about respective spaced first and second axes perpendicular to said sides, each said actuating devices including means coupled to said top and bottom portions for simultaneous rotation about a different axis and translating relative to the bottom portion transversely the lift direction in response to said rotation to effect said rocking movements.
