<p>The invention allows simpler folding-down requiring less effort. It comprises a head (3) that can be affixed to the fold-down part (1), and an actuator for actuating the head (3). Each head (3) comprises: a rod (5) to which an arm (6), which can be affixed to the part (1), is secured, in order to pivot about a pivot shaft (8) coaxial with the rod (5); a pinion (9) mounted on the rod (5); a worm (10) for actuating the pinion (9); a cable (11), the end (12) of which is affixed to the worm (10); and a transmission component (13) connected rotatably at one end (20) to the actuator (4), wherein the rotation of the transmission component (13) gives rise, in succession, to: twisting of the cable (11), rotation of the worm (10), and rotation of the pinion (9), of the first rod (5), of the arm (6) and of the part (1).</p> |
