Abstract: A locomotion device for physically disabled persons, comprising: a chassis (10) mounted onto a pair of rear wheels (11) and a pair of front swiveling wheels (12); a seat frame (20) frontally articulated to the chassis (10), so as to be displaced between a substantially horizontal first position and a second raised position that is markedly downwardly forwardly inclined; a backrest frame (30), which is interiorly articulated to a rear portion of the seat frame (20) and to the chassis (10), in order to be displaced between a first position, which is substantially orthogonal to the seat frame (20), and a second position, which is substantially coplanar to said seat frame (20); an impelling means (40), which is operatively coupled to the chassis (10) and to the seat frame (20), in order to provide the selective displacement of the latter between the first position and the second position; a movement locking means (50), which is mounted to the chassis (10) to allow the selective locking of the rear wheels (11); an
