Abstract: In one embodiment, there are power floor boards for a motorcycle or other two or three wheeled open vehicle, that is capable of using foot rests, such as an ATV. Each power floorboard has a toe part and a heel part. The two parts move from a first position where they are essentially flat on top and fully retracted, to a second position where the toe pad is angled up with respect to the heel pad, and both the heel and toe pads are fully extended toward a front of the vehicle. The toe pad is on rails and moves forward by a worm gear. The rails are fixed to the vehicles footrest mounts. In a particularly preferred embodiment of the invention, the angular motion of the toe pad compared to the relatively linear or flat motion of the heel pad, is achieved by a pivotable connection of the toe pad to the heel pad, and an elongated, relatively S-shaped cam slot with a follower therein for driving the toe pad first to slowly incline, then to faster incline, and then to slowly incline.

Abstract: In one embodiment there is a lumbar support system for fitting on a motorcycle or other similar vehicle. There is a bracket for connecting the lumbar support to the seat pan. There is a mechanism for pivotably connecting the bracket to the lumbar support. There is a mechanism for connecting the seat pan adjustably to a rear fender of the vehicle. The height of the lumbar support may be adjustable. The pitch and lateral position of the support may also be adjustable. There is also an air cushion with multiple chambers disposed within a recess in the seat pan, such air cushion and seat pad being covered with foam and a leather, vinyl or other cover.
