Trackless Seat Adjuster

Inventor: Rudolf Gruber, Markham, Canada Date of Patent: Dec. 5, 1995 Patent Number: 5,472,165 United States Patent

A seat adjuster comprising a system of linkages utilizing the effect of a compensating primary link which compensates for the normally uncompensated arcuate motion of the primary links. The links are attached to the riser, or the seat bottom and cooperate with each other in motion through the compensating link which is attached to the riser if the links are attached to the seat bottom and vice versa. The motion of the compensating link combines with the motion of the primary links to provide a substantially linear fore and aft motion to the seat.
