It is reported on reliable authority that there are over 500,000,000 handicapped people in the world,which is about 10% of the whole population. And 15,000,000 will join them every year.

Many people among them need wheelchair.Wheelchairs being in use is inevitably with the development of society and civilization.

Several important principles which make the wheelchair user feel comfortable are summerised. Knowledge of Ergonomics, Physiology, Anthropomethy, Modern mechanism design, Aesthetics etc. is used to discuss the principles of wheelchair static comfortability.A new type of wheelchair for cerebral palsy patients was designed according to the symptom of cerebral palsy patients, and some...
