Abstract
A wheelchair having a tiltable and translatable seat for compensating for shifting of the center of gravity of an occupant during tilting is provided. Such a wheelchair includes a frame, a first actuator, a seat assembly, and a first rigid link. The first actuator includes opposing front and rear ends coupled to the frame, a rod that extends between the front and rear ends, and a connector that is capable of translating in response to actuation of the rod. The seat assembly is directly coupled to the connector of the first actuator. The first rigid link has a front end and a rear end. The link front end is pivotably coupled to the frame, and the link rear end is pivotably coupled to the seat assembly. The link may be oriented such that as the connector translates, the first link impels the chair to tilt.
