Abstract
A seat cushion assembly includes a seat cushion frame operatively coupled to a seat track assembly by a seat cushion height adjuster for selectively positioning the seat cushion frame between a raised position and a lowered position. The seat cushion height adjuster includes front pivot shaft and rear pivot shaft journaled to the seat track assembly. A front pair of pivot links pivotally interconnect the seat cushion frame to the front pivot shaft and a rear pair of pivot links pivotally interconnect the seat cushion frame to the rear pivot shaft. A horizontal link interconnects each of the pairs of front and rear pivot links for synchronized movement. The adjuster further includes a powered drive assembly having a motor and gear box supported by a motor bracket between the front and rear pivot shafts for driving a screw shaft. A screw nut is threadedly coupled to the screw shaft for movement therealong. A torque bracket is coupled between the screw nut and the rear pivot shaft for rotating the rear screw shaft. When the screw shaft is rotated by the motor, the screw nut travel along the shaft and rotates the torque bracket and rear pivot shaft. The rear pivot shaft rotates the rear pivot links about an arcuate path to raise or lower the rear of the seat cushion frame. The horizontal links rotate the front pivot links about an arcuate path to simultaneously raise or lower front of the seat cushion frame.
