Actuator for a rear panel on a motor vehicle

A device for controlling a rear panel (4) of a motor vehicle provided with a rear boot (2), a lid (3) for said boot (2), and a roof which can be folded from a position in which it covers the vehicle cabin to a position in which it is stored in the rear boot (2), said roof comprising at least one rear roof part (5), characterised by the fact that it comprises on at least one of the sides of the vehicle:

• a panel support member connected to the vehicle chassis by pivoting means so that said panel passes, by means of a pivoting of said support member, from an open position in which said panel is substantially vertical and in which it leaves clear a passage for said roof, to one of two closed positions where said panel extends substantially horizontally in a position of closure of said passage between the chassis and the front edge (16) of the lid (3) of said rear boot in the first closed position, and between the chassis and a rear edge of the rear part (5) of the roof in the second closed position;
• means of moving said rear panel (4) in translation with respect to said support member;
• means of elastic return of said panel (4) with respect to said support member in the direction of said lid (3);
• and
• means of abutment (13, 14) between said panel (4) and said rear part (5) of the roof when the latter is in the closed position.
