ABSTRACT:
This invention provides for a shock absorber or spring mounting attachment which can be mounted on virtually all existing wheelchair frames in order to cushion the occupant from the shock and jolting now experienced when the main drive wheels of the chair pass over irregularities in the traveled surface. In addition, this attachment reduces the tilting experienced and reduces the traction lost when the wheelchair negotiates irregularities in the traveled surface. The attachment comprises a swing arm portion for rotatably supporting a drive wheel which is coupled to housing having a compression spring therein transferring the wheelchair weight to the wheel.
