This invention provides a wheelchair small wheel suspension system which optimizes parameters of height, trail, and forward extension of the small wheels to provide a wheelchair with maximum stability and ability to negotiate rough surfaces. This suspension system is applicable to both manual and powered chairs. It uses an elastomer block to cushion the impact of road surface imperfections. The location of the elastomer block with respect to the wheel and the system's connection to the wheelchair frame is an important aspect of this invention. Tuning of the wheelchair suspension system to meet the individual user's requirements is easily accomplished using this suspension system. |
