    Abstract: A curb-climbing rear wheel drive power wheelchair is disclosed having a pair of drive wheels, at least one ground-engaging idler wheel connected to the frame forward of the drive wheels and at least one anti-tip wheel mounted above ground aft of the drive wheels. Each drive wheel and an associated drive assembly are mounted to a motor support bracket that is pivoted to the frame of the wheelchair.

  • Anti-tip caster suspension for a wheelchair
    Patent number: 6543798
    Abstract: An anti-tip suspension for a wheelchair having rear casters is defined. The suspension includes a rocker arm support, a rocker arm and a spring. The rocker arm is pivotally attached to the rocker arm support so that it is rotatable with respect to the rocker arm support. The spring engages the rocker arm and rocker arm support, biasing them away from one another. The rocker arm includes a rotation limiter that limits the rotation of the rocker arm with respect to the rocker arm support in one direction.
