Abstract (en)
The wheelchair consists of a frame supporting an articulated structure comprising a seat base, a foot rest, a back and two symmetrical articulated systems at the sides, each made up of a deformable quadrilateral (17) with upper and lower bars, a deformable polygon and a spacer (20). It also includes an automatic mechanism (60) that modifies the angle of the seat back relative to the vertical in the saggital plane as it moves between seated and upright positions. The mechanism includes the spacer and deformable quadrilaterial, which has a shape other than a parallelogram, and it is adjustable to allow a selection of the direction of modification and/or the amplitude of modification.
