<p>A wheelchair has a seat frame (18) and a back frame (22), the wheelchair being configured to tilt the seat frame from an initial position to a tilted position. The wheelchair includes a rear anti-tip wheel (80) pivotally mounted for vertical articulation within a first range of motion. A means for limiting the vertical articulation (118, 120) to a second narrower range of motion in response to tilting of the seat frame is provided.</p> |
