Abstract: A personal ability vehicle (PMV) includes a frame with front and rear subframes. A steering mechanism is mounted on the front subframe and includes a steering front wheel connected to a tiller. The rear subframe includes a suspension mount comprising a pair of rear support legs. An anti-tip suspension includes a pair of trailing arms each mounting a trailing wheel. Each trailing arm is pivotally mounted on a respective support leg whereby the suspension is inevitable through a limited range of motion about a transverse suspension pivotal axis. A pair of spring assemblies are attached to the trailing arms and are adapted for selectively engaging the support legs to provide a counter-rotational torque force around the suspension pivotal axis in order to resist backwards tipping of the PMV, for example, when it is ascending an inclined sloping surface. Relatively uniform proportional, weight distribution on said steering front, main and trailing wheels is maintained throughout a range of loads.

Abstract: A bariatric transport is provided. The transport includes a bed area for use by a bariatric patient. The transport further includes a drive assembly that is operable to selectively drive the transport in forward and rearward directions and permit turning of the transport with little or no lateral movement of the transport. Leading and trailing stabilizing wheel assemblies are provided that are selectively moveable into and out of engagement with a supporting floor. Drive devices are also provided to provide selective elevating and lowering of various components of bariatric patient supports.
