Abstract

A quick adjust power adjuster for adjusting the position of an upper track relative to a lower track of a seat track assembly comprises an elongated guide rod extending axially between opposite first and second ends and fixedly secured to the lower track. A tubular lead screw is slidably coupled to the guide rod. A driven assembly is operatively coupled to the tubular lead screw for axial travel along the tubular lead screw in response to rotation of the driven assembly. A drive assembly is fixedly coupled to the upper track and operatively coupled to the driven assembly for selectively rotating the driven assembly in opposite first and second directions for axial travel along the tubular lead screw. A release mechanism is coupled to the lower track and operable between a locked condition coupled to the tubular lead screw to prevent sliding movement of the tubular lead screw along the guide rod wherein the driven assembly and the drive assembly move axially along the tubular lead screw to slide the upper track relative to the lower track in a power operation mode and an unlocked condition decoupled from the tubular lead screw to allow sliding movement of the tubular lead screw along the guide rod while the driven assembly and the drive assembly remain axially fixed to the tubular lead screw to slide the upper track relative to the lower track in a manual operation mode.
