Abstract
A main T-shaped lever 3 is articulated at the ends of its horizontal arm on two links 5, 6 mounted so as to pivot on a support plate 1 in such a way that the four axes of articulation A, B, C, D form a deformable isosceles trapezoid when the main lever is in the central position E of its travel which, moreover, is parallel to the front 2 of the plate. Secondary levers 9, 10 actuated by cams 5a, 5b, 6a, 6b act on the air-conditioning controls 13, 14. Particular application is to the case of multiple controls manipulated by a single lever with a large straight displacement with no deflection.
