MOTORIZED WHEELCHAIR CHASSIS AND MOTORIZED WHEELCHAIR COMPRISING THE SAME

There is described a motorized wheelchair chassis comprising a frame assembly including a first frame element that supports first and second caster wheels at an end of the first frame element, which first frame element is designed to support a seat assembly, a battery support assembly secured to an underside of the frame assembly and supporting at least one battery, first and second power drive assemblies disposed on lateral sides of the battery support assembly, and first and second drive wheels driven by the first and second power drive assemblies, respectively. The frame assembly further comprises a second frame element, which is secured to the battery support assembly, and the first frame element is supported onto the second frame element via a coupling structure comprising a ball-joint bearing permitting relative movement of the first frame element with respect to the second frame element in more than two degrees of freedom within a limited range of movement.
