Abstract:

A personal mobility vehicle includes a frame with a pair of parallel tracks for moving the vehicle, the track having a lower surface forming a drive plane for the tracks. A seat is operably mounted on the frame, and has a support for moving the seat about a generally horizontal axis normal to a longitudinal axis of the tracks, to maintain the seat in a generally upright position as the vehicle moves up or down a slope. The seat is also operably mounted for rotational movement on a vertical axis, to permit the seat to swivel. A lifter arm is operably mounted on the frame, with a forward end pivotally connected to the frame at a location spaced above the drive plane, and a rearward end pivotal between a lowered position spaced below the drive plane and a storage position spaced above the drive plane. A cylinder selectively raises and lowers the lifter arm to assist the vehicle in traversing the upper end of a flight of stairs, in either the ascending or descending directions.
