ABSTRACT:
A mechanism used to control the vertical height as well as fore-aft position of a vehicle seat while presenting a minimum height profile when adjusted to minimum vertical elevation. The seat is connected to a pair of rails, one stationary and one reciprocable. A seat is affixed to an attachment bracket which is connected to the reciprocable rail by a vertical height adjuster comprising a vertically oriented screw jack which may be positioned to selectable heights by a motor. The fore-aft relationship of the rails may also be selectively adjusted by a motor driving a horizontally oriented screw jack. Both screw jacks incorporate a screw connected to a helical gear engaged to a worm gear. The worm gear is driven by a remote motor through a flexible drive cable. Both screw jacks present a structure which offers a minimum height profile when the seat is positioned at minimum vertical height. In this manner, an aerodynamically efficient roof line may be utilized while providing maximum head room for the vehicle occupants.
