Abstract: An apparatus for separating fluid flows in a heating device, particularly for heating the interior of a motor vehicle is proposed, the heating device having at least one heater equipped with a plurality of lamellar heat emission or delivery elements. In order to ensure an easy, inexpensive separation of several fluid flows and in particular also downstream of the heater equipped with the lamellar heat emission elements, according to the invention a substantially plate-shaped separator is provided having an opening with a contour adapted for the pushing of the separator onto the heater equipped with the lamellar heat emission elements. The invention also relates to a method for separating several fluid flows in a heating device of the aforementioned type.

Abstract: The invention refers to a motor vehicle heating system comprising several heating elements, several voltage connectors for connecting the heating elements to a supply voltage, and a plug-on connector receptacle in which the voltage connectors are arranged as contact reeds. According to the invention the plug-in connector receptacle is provided with a ground pin for connecting of the motor vehicle heating system to ground.

Abstract: For a rotary switch (7) fastened on a dividing wall (1), it is proposed to illuminate the adjusting knob (4) by means of transmitted light by providing as a light guide (20) a conical ring (28) formed with continuations (29, 30, 31) formed on in the axial direction, the continuations (29, 30, 31) reaching through the dividing wall (1) and being aligned with light-emitting diodes (8, 9), which are located on a printed-circuit board (6) assigned to the rotary switch (7). The light guide (20) is fastened on the dividing wall (1) indirectly by fastening the housing (3) and is secured against twisting by suitable indentations (47, 48, 49) in the dividing wall (1).

Abstract: The housing, which is to accommodate a rotary switch arranged on a printed circuit board, is provided with a threaded projection which can be used to fasten it to a wall through which a setting stem, which is assigned to the rotary switch, reaches. The housing is designed in two parts in such a manner that one half (19, 20) of the threaded projection is integrally formed on each housing component (9, 10). The two housing components (9, 10) are joined together by means of latching connection means (11, 12, 13, 14) and hooks (one of which is denoted by 16) engaging in eyelets.
