Abstract
A dampening system is efficient in dampening vibration through a wheelchair frame. The system allows a lower base frame and wheels to be rigidly attached, while an upper seat frame is joined to the base frame through elastomeric dampening bushings to isolate the seat frame from the base frame. The bushings may be hidden in vertical upright tubes of the base frame. The bushings can also be used for supporting front caster forks and/or a rear axle assembly in isolation to the base frame.
