ABSTRACT:
A wheelchair includes a chassis with rear wheels and front wheels mounted thereto. A support is pivotally coupled by a pivot axis to the chassis. A seat mount is pivotally coupled to the support. An electric actuator can move the support to cause the seat mount to be moved between raised and lowered positions. A clearance is provided between one or more power supply units and suspension mounts to enable the support to move therein during movement of the seat mount to and from the lowered position. The support and actuator are mounted by a mounting assembly that is mounted by guides so that the mounting assembly can be raised by the actuator to further elevate the seat mount.
