The nacelle (11) carries the end element (21) and is connected by four ball joints (9,10) to two legs each formed from two support bars (7,8) forming deformable parallelograms mounted on runners (3,4). The pivoting plate (29) articulated on the nacelle about the spindle (30) is subjected to control bars (27), pivoting control bars (14) and lateral displacement bars (18) connected respectively by ball joints (26,13,17) to the runners (3,12,23). |
