The present invention concerns two models (Model A and Model B) of a wheelchair that comprises, an independent back of the seat that is bipartite (1) with adjustable inclination and is articulated to open and close horizontally. According to the invention, the bipartite seat base (11), that is independent of the back of the seat (1) and of the armrests (7), performs an automatic and delayed inward and outward horizontal motion (implemented differently in Model A and Model B). The footrests (39) are articulated to permit the independent movement and inclination of the columns (36) of the footrests permiting, in this way, the transmission of some movement to the users' legs, and having in Model B a mechanism (36 and 38) for adjusting the height and the inclination of the columns of the footrests. The tipped "U" shaped chassi, complemented by the disposition of the wheels, result in an empty space (56) beneath the seat that will permit the wheelchair to penetrate over the toilet seat or over a bed and having in Model B a mechanism for adjusting the height of the wheelchair whilst the user isseated on it. Finally, a central articulated structure (44) permits the folding of the wheelchair for transportation purposes. |
