A wheelchair suspension comprises a frame, at least one pivot arm, at least one front caster, at least one rear caster, a stabilizing system, and a sensor. The pivot arm is coupled to the frame. The front caster is coupled to the pivot arm. The rear caster is coupled to the frame. The stabilizing system is coupled to the frame and the pivot arm. The sensor is arranged such that tipping of the frame causes actuation of the stabilizing system to at least partially resist further movement of the frame.

A wheelchair accessory apparatus is disclosed. The wheelchair accessory apparatus includes an ambulatory assistive device retaining member removably attachable to the frame of a wheelchair and an ambulatory assistive device support member removably attachable to the footrest of a wheelchair. The ambulatory assistive device retaining member includes a first leg, a second leg, and an elongated stem. The first leg and the second leg join and define a portal therebetween to receive an ambulatory assistive device therethrough. The ambulatory assistive device support member includes a body comprising a cup sized to removably receive a crutch tip. When the ambulatory assistive retaining member and the ambulatory assistive device support member are both attached to the wheelchair, the portal and the cup align to receive and sustain an ambulatory assistive device therein for hands-free transportation of the ambulatory assistive device while utilizing a wheelchair.

In a preferred form the invention there is a lateral support forming part of a seat of a wheelchair, comprising a bracket (1), a hinge body (2), a forward plate (3) having padding and a lever (17). The lever (17) is arranged so it can be turned by hand to move a bolt (18) into a pin (5) whereby the hinge body is prevented from swinging about the pin. The lever (17) is also arranged so it can be subsequently turned by hand to cause a cam face (21) of the lever to ride along a complimentary engaging surface (22) of the hinge body. This forces the bolt (18) from the pin (5) thereby freeing the hinge body (2) to swing about the pin (5) and, as a consequence, to swing the plate (3) to facilitate access to the seat.

An ergonomically designed seating apparatus having a seat and a backrest. The seat having a seat frame securable to a chassis, a seat support pivotally connected to the seat frame, and at least one first resilient member positioned between the seat frame and the seat support permitting resilient relative pivotal tilting between them. The backrest having a back frame securable to the chassis, a lumbar support connected to the back frame, a back support pivotally connected to the lumbar support, at least one second resilient member positioned along surfaces of the lumbar support and the back support permitting resilient relative pivotal tilting between them, at least one pivot arm connected to the back support configured to limit the pivotal range of motion of the back support, and at least one pivot block connected to the lumbar support configured to interact with the at least one pivot arm.
