摘要

There is described a motorized wheelchair chassis (1) comprising a frame assembly (2) including a first frame element (20) that supports first and second caster wheels (4a, 4b) at an end of the first frame element (20), which first frame element (20) is designed to support a seat assembly, a battery support assembly (6) secured to an underside of the frame assembly (2) and supporting at least one battery (61, 62), first and second power drive assemblies (5a, 5b) disposed on lateral sides (6a, 6b) of the battery support assembly (6), and first and second drive wheels (3a, 3b) driven by the first and second power drive assemblies (5a, 5b), respectively. The frame assembly (2) further comprises a second frame element (25), which is secured to the battery support assembly (6), and the first frame element (20) is supported onto the second frame element (25) via a coupling structure (200) comprising a ball-joint bearing (210) permitting relative movement of the first frame element (20) with respect to the second frame element (25) in more than two degrees of freedom within a limited range of movement.
