Abstract (en)
It is a folding wheelchair for disabled persons characterized in that the folding and the opening can occur by only one hand acting on the top of a post of the backrest let it collapse moving it against the seat and let it raise taking it to the vertical position. The post of the backrest is so structured in order to achieve a lever with unequal arms which transmits the force by kinematic mechanisms which let the owned angular position change by turning elements of the kinematic panthografic system which connects one to the other the bearing structures of the sides of the wheelchair (Fig. 4). <IMAGE>
