Abstract

A motorized wheelchair includes a frame, a battery support assembly that supports a battery box and is connected to the frame, first and second power drive assemblies disposed on each lateral side of the wheelchair, first and second rear wheels driven by the power drive assemblies, and first and second castor wheels that are pivotally connected to said frame. The battery support assembly is pivotally connected to the frame by a first connecting arrangement, so that said battery support assembly can pivot around a first longitudinal axis. The battery support assembly is pivotally connected to the first connecting arrangement by a second connecting arrangement, so that the battery support assembly can pivot around a second lateral axis.
