The invention is directed to a collapsible frame ( 1; 31; 51 ) for a pushchair, comprising a chassis ( 4; 34; 54 ) with several wheels ( 2, 3; 32, 33; 52, 53, 53' ), a frame ( 5; 35; 55 ) supporting the body ( 6 ), particularly a seat, shell, pouch or similar for a child, and a folding mechanism ( 7; 37; 57 ) arranged betweem the same, to change the separation of the support frame ( 5; 35; 55 ) of the body ( 6 ) from the chassis ( 4; 34; 54 ), whereby the folding mechanism ( 7; 37; 57 ) comprises at least two parallel arms ( 18, 19; 40, 41; 66, 67 ) connected in the style of a parallelogram link to the chassis ( 4; 34; 54 ), at one side and the to the support frame ( 5; 35; 55 ), on the other side. According to the invention, the connecting line between the joints points of ( 39: 65 ) of both arms ( 18, 19; 40, 41; 66, 67 ) of a pair on the chassis ( 4; 34; 54 ) include a greater angle with the horizontal contact plane of the wheels ( 2, 3; 32, 33; 52, 53, 53' ) than with the verticals running perpendicular to that plane.
