  • Patent number: 6712369
    Abstract: An electrical wheelchair includes a chassis to which a frame is pivotally mounted. Two casters are rotatably mounted to the frame. At least a resilient member is arranged between the frame and the chassis for supporting the relative position of the frame with respect to the chassis. The resilient member can be deformed to change the relative position of the frame with respect to the chassis to allow the wheelchair to climb over raised surfaces of different heights. The deformation of the resilient member also stores energy therein which may be released when the wheelchair is about to reach the raised surface for enhancing the wheelchair to move over the raised surface. Further, the resilient member also functions to absorb shock caused by the wheelchair moving down a step-like raised surface.
