<p>The assembly has a gap (12) partly delimited by a bottom plate (10) fixed with respect to a mounting (5) and an upper plate (11) articulated on a hinge (15) fixed with respect to the mounting, where the plate includes an axis parallel to pivots (4). The upper plate is guided on a curved groove (17) carried by a flange (20) secured to a cradle (2). A profile of the groove is defined in order to ensure that the upper plate is positioned parallel to the bottom plate over 50% of pivotal clearance of the cradle on the pivots.</p> |
