Abstract
The invention concerns a control panel for a motor vehicle system comprising a housing supporting at least a double control unit formed by two rotating knobs arranged projecting relative to the housing and respectively coupled with two shafts, which are capable of being connected to the system elements. One of the shafts bears a coaxial worm screw for driving in rotation a toothed wheel about an axis orthogonal to the shaft axis, said toothed wheel capable of being functionally coupled with a first member of the system, while the other shaft is parallel to the first shaft and is capable of being functionally coupled with a second member of the system. The invention is particularly applicable to heating-ventilating and/or air conditioning systems.
