Reclining back with anti-tip protection for wheelchairs |
摘要 |
A wheelchair has a seat, a reclining backrest and anti-tip legs movable between a retracted position and an extended ground contacting position in response to movement of the backrest between an upright and a reclining condition. The inclination of the backrest can be conveniently adjusted by a person seated in the wheelchair by latching a pair of detent arms in one of several slots spaced under the chair's armrests. The anti-tip legs extend to support the wheelchair against tipping backwards when the backrest is reclined and retract out of the way when the backrest is brought upright.
