ABSTRACT:
A vehicle seat equipped with at least one mechanism for adjusting the height of the front or of the rear of the sitting portion or the tilt of the seat back.
The control lever of this mechanism is brought forward to the front of the seat and its rotations are transmitted by a chain and toothed-wheel system to a bar equipped at both ends with rollers having two pins adapted to coact respectively with horizontal apertures in the sitting portion and with vertical sets of teeth in the base.
The preferred application of the invention is to seats mounted so that no space is available laterally for the usual control members of the adjustment mechanisms.
