Abstract: An ambulation aid which has a support structure for the patient that both supports the patient's weight, and is movable laterally with respect to the frame to accommodate sideways hip movement of the patient's gait. The inventors have observed that a patient's hip will shift laterally as the patient steps forward and places weight on the forward stepping leg. This causes prior art ambulation aids to jerk sideways. The present invention overcomes this by providing a support structure which can move sideways without requiring the entire frame to move sideways. In one embodiment, the support structure slides in a track behind the patient, allowing lateral movement. In another embodiment, the support structure includes a belt which either slides through rollers behind the patient, or is attached but is flexible to allow hip movement, or is attached to a slider behind the patient.

Abstract: A cambering vehicle includes a single steerable front wheel and a pair of rear wheels at the rearward ends of trailing arms extending from the front structure. The two arms are articulated to the front structure, and move arcuately in planes parallel to the steering column. In one embodiment the arms are linked by a yoke, and traverse equal arcuate distances in opposite directions relative to one another.
