ABSTRACT:
A power seat track apparatus for selectively positioning an automotive vehicle seat. The apparatus is adapted to be powered by electric motor drive, preferably with separate motors for each drive direction. The seat back is mounted on the upper track of the seat track mechanism for horizontal drive with the track. The vertical drive through front and back torsion tubes or bars act on only the seat pan and seat cushion but not the seat back. Since the vehicle shock loading requirements must be met by the structural seat pan or seat frame, the pan for holding only the seat cushion may be reduced in size as compared to the usual power seat frame. The back cushion seat mounting is designed to withstand shock loading by its mounting on the upper seat track separate from the seat pan and cushion elevating mechanism.
