Abstract
Abstract A device is disclosed for the automatic remote control and locking of a trunk lid or hatchback 1 connected by a hinge to the upper part of an automobile body around a transverse axis 2 and balanced by a stabilizing device. The hatchback 1 may be controlled by means of a rod 12 which is connected at one end to the hatchback and at the other end to a point of a first cogged sector 17 which is caused to rotate, along a predetermined path, by a remote-controlled electric motor 11. The hatchback may, in addition, be automatically locked after folding back onto the body portion of the trunk 3 by mechanical means 13, 18, 31 brought into play by the electric motor once the rod and first sector have stopped working.
