The invention concerns a child car safety seat designed to be mounted on a motor vehicle seat, comprising a shell (2) forming a seat bucket having lateral sides (23, 24) and a frame supporting (3) the shell (2), adapted to be installed on the motor vehicle seat, the shell being mobile relative to the support frame via a device (9) adjusting the inclination comprising a rotary screw (10) co-operating with a pivoting nut (11), the lateral sides (23) of the shell being mounted pivoting via a width-adjusting device (25). The width-adjusting device comprises a rotary element (26) mounted about the rotary screw of the inclination-adjusting device so as to rotate freely relative to said screw. A device transmitting the rotational movement is mounted between an actuating roller (31) and said rotary element (26). Two connecting rods (27), of substantially the same length, are articulated each at one of their ends on said rotary element (26) and at their other end on a shaft (29a, 29b) supporting and pivoting the shell lateral sides.
