A stand-up type wheelchair for handicapped and sick people comprises a chassis ( 2 ) supporting an articulated structure ( 12 ) which includes a seat, a foot-rest, a chair-back, and two symmetrical lateral articulated systems. Each system includes a first deformable polygon contributing to the support of the seat, a second deformable polygon, contributing to the support of the foot-rest, a chair-back quadrilateral (four-bar linkage) ( 35 ) articulated on the first quadrilateral, and a manoeuvring assembly ( 40 ), which includes a first lever ( 41 ), a second lever ( 43 ), and a manoeuvring handle ( 49 ). The manoeuvring handle ( 49 ) is articulated firstly on the second lever ( 43 ) and/or the first lever ( 41 ), and secondly on the first quadrilateral by means of a connecting-rod ( 55 ) whose first extremity is connected by a pivot to the first quadrilateral and whose second extremity is connected by a pivot ( 58 ) to the manoeuvring handle ( 49 ).
