A wheelchair is a wheeled mobility device in which the user sits. The device is propelled either manually (by turning the wheels by the hand) or via various automated systems. Wheelchairs are used by people for whom walking is difficult or impossible due to illness (physiological or physical), injury, or disability.*** People with both sitting and walking disability often need to use a wheelbench.
The earliest record of wheelchairs date back to the 6th century, and was found inscribed on a stone slate in China. Later dates relate to Europeans using this technology, dating back to the German Renaissance. Harry Jennings, a mechanical engineer, invented the first lightweight, steel, collapsible wheelchair[1] in 1933 (date?) together with his disabled friend and fellow engineer, Herbert Everest, who had broken his back in a mining accident. The two saw the business potential of the invention, and went on to become the first mass-manufacturers of wheelchairs: Everest and Jennings. Their "x-brace" design, albeit with updated materials and other improvements, is still in common use, over 70 years later
*** the wheelchair is a beautiful machine. all people are beautiful. the humans in this video were mid-day drunk, and thereby slightly disabled, though, inspired by the amazing physics of the wheeled bench enough to put the respect to a physical challenge.
sick maniacs.
