The invention relates to a method and an arrangement for regulating air mixing in a heating and/or air-conditioning system of a motor vehicle. In the system, recirculated air and/or fresh air is/are distributed via air-flow control elements to different air vents and supplied to the passenger compartment. In order to optimize energy consumption and provide a simpler and therefore more cost effective arrangement, the proportion of recirculated air is determined as a function of the position of the air-flow control element(s). The control unit is designed in such a manner, e.g., by implementation of a computer program, that signals being emitted by the control unit for opening the recirculated-air intake opening are dependent on, inter alia, the position(s) of the air-flow control element(s).

An apparatus as recited in claim 1 wherein the cantilever support structure includes: (a) a vertical member on which the top belt guard support is pivotally supported and the bottom belt guard is pivotally supported; and (b) an intermediate support in which the top belt guard support and bottom belt guard support are supported vertically, the intermediate support is positioned between the vertical member and the protected zone and having means compensating for floor undulations and changes in vertical belt positions. 3. An apparatus as recited in claim 1 in which the cantilever support structure has a means to advance the cantilever support structure to a next incremental position for permanent belt structure assembly. 4. An apparatus as recited in claim 3 including a means for maintaining alignment of the permanent belt support structure during assembly of the permanent belt support structure. 5. A method of installing permanent conveyor belt support after a conveyor belt has been advanced toward a forward tail piece comprising: (a) providing a safety guard unit which supports the conveyor belt in which a top belt is supported and a bottom return belt is substantially enclosed and supported, the safety guard unit forms a protected zone; (b) supporting the safety guard unit by a cantilever support structure located at an end of the safety guard unit toward a forward tail piece in which most of the weight of the safety guard unit is supported by the cantilever support structure and most of the weight of the top belt in the protected zone is supported by the cantilever support and most of the weight of the return belt in the protected zone is supported by the cantilever support; and (c) installing permanent conveyor belt supports within the protected zone. 6. A method as recited in claim 5 wherein the cantilever support structure includes: (a) a vertical member in which the top belt guard support is pivotally supported and the bottom belt guard support is pivotally supported; and (b) an intermediate support in which the top belt guard support and bottom belt guard support are supported vertically, the intermediate support is positioned between the vertical member and the protected zone and having means compensating for floor undulations and changes in vertical belt positions. 7. A method as recited in claim 5 including advancing the cantilever support structure to a next incremental position for permanent belt structure assembly. 8. A method as recited in claim 7 including maintaining alignment of the permanent belt structure during assembly of the permanent belt structure.
