<p>An anti-tip device for a wheelchair (19) which also facilitates climbing comprise stabilizer wheels (13) which normally have no contact with the base or ground on which the wheelchair moves. The stabilizer wheels (13) are rotatably mounted at the front ends of bars (15) extending forwards beyond the front wheels of the wheelchair. The stabilizer wheels are thus located in front of the ordinary wheels of the wheelchair and their lower sides or edges are located in a plane located above the plane which passes through the lower sides or surfaces of the ordinary support wheels of the wheelchair. The bars (15) are relatively long and can move elastically and they have guides so that the stabilizer wheels (13) can move in vertical planes upwards from the rest position. An adjustment device restricts the upward movement.</p> |
