    摘要： A personal mobility vehicle includes an base unit having a frame and front and rear pivot arms pivotally mounted at respective front and rear pivot points. The front and rear pivot arms support casters. A drive unit having a ground engaging mid-wheel drive wheel is connected to the frame. A linkage connects the front and rear pivot arms to each other in a manner such that an upward or downward rotation of one of the pivot arms about its pivot point causes rotation of the other pivot arm about its pivot point in an opposite rotational direction. The base unit may also include a drive unit that is pivotally supported on the base unit by a torque arm and a suspension system that includes a suspension stop. The torque arm selectively disengages the suspension stop to allow movement of the front caster wheel in response to the terrain traversed.

    摘要： An armrest mounting assembly (20) for mounting an inverted, U-shaped, armrest assembly (14) to a wheelchair having a frame (10). The mounting assembly (20) includes a body (22) which is formed to receive an end of the armrest post portions (17). Releasable fasteners (29) couple the body (22) of the armrest mounting block to the wheelchair frame (10). The mounting assembly (20) includes a mounting groove (28) defined by the body (22) proximate a frame engaging surface (24) of the body (22). The groove (28) is formed and dimensioned to slidably receive an enlarged head (36) of the fastener (29) for movement of the mounting block (20) through a plurality of positions along the wheelchair frame member (18) when the fastener (29) is not tightened. This movement permits alignment between the armrest post portion (17) and mounting body (22). Further, the groove (28) retains the head (36) of the fastener ( 29) against rotation for tightening of the fastener (29) to secure the mounting block (20) in alignment with the spaced apart armrest post portions.

    摘要： A wheelchair frame has first and second side frames, a slider housing, and a slider member mounted for movement relative to the slider housing. Links connect the slider housing to both the first and second side frames, and links connect the slider member to both the first and second side frames. Movement of the slider member relative to the slider housing actuates the links to change the spacing between the first and second side frames, thereby opening and closing the wheelchair frame.

    摘要： The back of a wheelchair user is independently supported along and about three mutually perpendicular axes. Two elongated adjustment arms are pivotally connected to extension arms which telescope into opposite ends of a hollow connecting tube. The support positions along and about the three axes is achieved by pivoting the arms and the connected relationships of a back shell and cushion to the connecting tube, while the adjustment arms remain pivotally connected to the wheelchair and the extension arms are telescopically retained in the connecting tube.
