ABSTRACT:
A support mechanism for 6-way adjustable automotive seats has a base and a seat support mounted on the base by mechanical locks telescopable for adjusting the height and tilt of the seat support. The mechanism is improved in that spring biased levers compensate for variable spring force to apply an approximately constant seat lifting force throughout the adjustment range of the mechanism.
