Stabilizing system for a reclinable wheelchair

摘要

A stabilizing system for a reclinable wheelchair connects anti-tip members to the wheelchair seat such that pivoting of the seat causes pivoting of the anti-tip members. In one embodiment, the stabilizing system includes cables connected at opposite ends to the seat and to the anti-tip members. The cables may be connected to the seat bottom or, alternately, to the seat back. The anti-tip members may incorporate a pivoting suspension member that includes a drive motor for the wheelchair. Pivot control mechanisms connected to the cables can be used to permit a predetermined amount of seat pivot without corresponding pivot of the anti-tip members. The stabilizing system alternatively includes axially compressible link members connecting the seat back to the anti-tip members to provide controlled pivoting of the anti-tip members based on pivoting of the seat.
