Abstract:
A mechanical device for adjusting the position of a seat mounted on a frame and a seat back mounted on said seat frame, said device comprising:a control element constructed with first and second cam surfaces, said element mounted on said seat frame for movement therewith and for rotation thereon, said control element having an access opening therein; a first actuator for adjusting said seat in a vertical direction, said first actuator having first triggering means; a second actuator for pivoting said seat about a first horizontal axis, said second actuator having second triggering means engaging said first cam surface for triggering movement of said second actuator; a third actuator for pivoting said seat back about a second horizontal axis, said third actuator having third triggering means engaging said second cam surface; a lever pivotally mounted on said control element for rotation in vertical and horizontal operational planes and extending radially thereon, said lever having an inner end, positioned to engage said first triggering means through said access opening and an outer end which is positioned for rotational movement by a user in said operational planes; wherein movement of said lever in said vertical plane triggers movement of said first actuator and movement of said lever in said horizontal operational plane moves said first and second cam surfaces to trigger movement of said second and third actuators.
