Abstract
A control unit for a heating and ventilating installation for an automotive vehicle, with or without air conditioning, comprises a module in the form of a housing, with two coaxial rotatable control knobs projecting from the outside of the housing and two coaxial shafts coupled respectively with the two knobs, each shaft rotating with the corresponding knob. Each shaft is also coupled with one of two transmission members rotatable with the corresponding shaft, the transmission members being mounted within the housing and arranged to act respectively on temperature regulating means and air distribution means of the vehicle, for passing the air into the passenger compartment or cab. The control unit also has a fixed intermediate sleeve arranged between the two shafts so as to prevent any interaction between the two control knobs.
