Suspension system for a wheelchair |
摘要 |
A suspension system for mounting a pair of wheels to a wheelchair is disclosed. The system includes a crossbar pivotally mounted to the wheelchair so as to pivot about a longitudinal axis. At least one spring assembly is located between the crossbar and the wheelchair frame for controlling the pivoting of the crossbar. A hinge assembly is mounted on each lateral end of the crossbar. The hinge assembly includes a first hinge component attached to the crossbar so as to be rotatable about a vertical axis, and a second hinge component resiliently connected to the first hinge component. The resilient connection biases the second hinge connection against rotation with respect to the first hinge component. A wheel and yoke assembly are mounted to the second hinge component.
