Abstract
A wheelchair suspension assembly includes a frame, a drive assembly, an anti-tip linkage, a front anti-tip wheel, and a rear anti-tip wheel. The drive assembly includes a drive wheel. The front anti-tip wheel is positioned forward of the drive wheel by the anti-tip linkage. The rear anti-tip wheel is positioned rearward of the drive wheel the anti-tip linkage. The anti-tip linkage couples the front anti-tip wheel to the rear anti-tip wheel such that upward movement of the front anti-tip wheel relative to the frame causes upward movement of the rear anti-tip wheel relative to the frame. The anti-tip linkage includes a front anti-tip pivot arm that is pivotally coupled to the frame, a rear anti-tip pivot arm that is pivotally coupled to the frame, and a connecting link that couples the front anti-tip pivot arm and the rear anti-tip pivot arm.
