The wheelchair, consisting of a frame (1) with rear (2) and front (3) wheels and handles (7), has a seat back (6) that can be set at a variable angle to the seat. The seat back has side tubes (5) with their lower ends pivoted in supports (9) and fitted with locks in the form of spring-loaded elements with transverse rods inside the side tubes that engage with selected notches in the supports. The spring-loaded elements are connected by cables inside the tubes to triggers (16) on the handles that release the locks for adjustment of the back position. |
