Abstract: The application relates to a fastening means for a gas cushion unit associated with a passenger seat in a motor car, where the gas cushion unit exhibits a housing which is slidable into a frame formed by fixed parts of the vehicle and is anchorable there by the cooperation of a central screw ehich penetrates frame and housing at their upper side and lower side. In order to achieve absolutely reliable anchorage for a minimum assembly outlay, it is provided according to the invention that a channel closed radially at least in sections and serving for the passage of the central screw is provided on the rear side of the housing at least on a part of its vertical extension.

Abstract: In an air-conditioning installation for vehicles with a blower for supplying fresh air to a vehicle interior space, with a temperature sensor for detecting the interior space temperature and with an air jet pump, consisting of a venturi pipe and of an air suction connection for producing an air flow over the temperature sensor, the air jet pump is arranged integrated in the blower for reducing the individual components for the temperature detection and for reducing the requisite installation space in the vehicle in such a manner that its air outlet opening lies within the blower stream. The temperature sensor is thereby so arranged that it is acted upon by the interior space air sucked-in by way of the air suction connection.

Abstract: A fresh air supply device is disclosed which is connected upstream of a blower of a heating or air conditioning unit in a motor vehicle. The blower is accommodated by a housing with the fresh air entering into a gap between the windscreen and the adjacent hood. The fresh air is deflected while water and foreign bodies are separated and is supplied to a filter underneath the hood. The filter can be exchanged by pulling it out upwards. Downstream of the filter, the air enters the intake side of the blower. In order to prevent unintentional heating up of the fresh air in the intake tract, while retaining easy exchangeability of the filter, the filter is covered by an intake scoop which can be moved away and is thermally shielded relative to the vehicle hood or bonnet.

Abstract: A sealing device is provided for sealing the bearing journal area of a rotatable flap within the housing of an air guiding duct which sealing device allows for a reliable sealing, increased rotational mobility of the flap and a saving of material cost and weight. The sealing device is formed with a sealing lip arranged over and extending around approximately half the circumference of a bearing journal creating a front-side sealing surface disposed against the interior wall of a housing. The sealing device is connected to the bearing journals and flap body by the engagement of connecting pieces into holes provided in the flap body and a flange provided on a bearing collar all displaced from the interior wall of the housing.

Abstract: In order to bring about, in the case of a crossflow heat exchanger with two heating sections which can be individually regulated through the heat transfer medium, a pipe routing adapted to the particular installation conditions in a motor vehicle, with minimum possible connections, the partition wall subdividing a central deflection header is provided with perforations further dividing both regions of the deviation zone for the heat transfer medium, for a purposeful routing of the heat transfer medium through integrated flow and return tubes from an outer deflection header to the respective opposite heating section. Only one flow pipe is connected to an outer deflection header and the two return pipes lead away from the same outer deflection header mutually separately for the heat transfer medium.

Abstract: A defroster air vent arrangement is provided for uniformly distributing the air flow discharged from a defroster onto motor vehicle windshields which defroster air vent arrangement allows for adequate defrosting of the entire windshield in an open and in a partially closed positioning of the defrosting device. The vent arrangement is formed with a defroster nozzle connected to an air distributor housing. A defroster nozzle is provided with a wall web dividing the defroster nozzle into air guiding ducts of unequal cross-sectional areas and the air distributor housing is provided with an adjustable covering device providing for a selectively independent regulation of the flow of the defroster air into the air distributor housing and through to the windshield.

Abstract: A system for the air-conditioning of the interior of a motor vehicle having an engine cooling circuit is provided which has a water/air heat exchanger and a water/water heat exchanger connected in series in the engine cooling circuit. The water/air heat exchanger is arranged upstream of the water/water heat exchanger. The water/water heat exchanger is between the water/air heat exchanger and panel heat exchangers which are located in the interior of the vehicle.

Abstract: A fresh air supply device in a motor vehicle which is installed in an accessories compartment. The engine compartment partition and passenger compartment partition which adjoin the accessories compartment are joined together in the center of the vehicle by means of a frame in which a lower trough-like casing part equipped with a blower is suspended from above. A water separator forming an integral component part of the upper casing part disposed on the lower casing part surrounds an upwardly projecting connection piece carrying a fine filter by its collecting vessel and by the two water outlets leading away therefrom.

Abstract: A heat exchanger for the independent heating of the driver and front-seat passenger side of a passenger space, having flow pipes located at the ends of the heat exchanger at the transition between the upper and lower water compartment. These flow pipes are connected to the central flow connection via a flow channel transverse to the central flow connection and corresponding juncture channel. The transverse channel is located above a collecting chamber which is located at the lower side of the upper water compartment. The flow pipes guide the flow from the upper water compartment to the lower water compartment. Return pipes are positioned to guide the flow from the lower water compartment into the collecting chamber in the upper water compartment. From the collecting chamber the flow travels out of the upper water compartment through return connections.

Abstract: A heating or air-conditioning system for passenger cars is described that is equipped with a main heat exchanger comprising a ribbed-tube block against which the air flows that is guided into the passenger space and of a forward-flow radiator tank through which water flows and a return-flow radiator tank. The heating or air-conditioning system is also equipped with one or several additional panel radiators that are connected to an additional circulating system and are arranged so that they are distributed at or in the interior of the vehicle. This additional circulating system has a forward-flow chamber that is assigned to the return-flow radiator tank of the main heat exchanger. As a result, the advantage is achieved that the panel radiators, during the heating operation, can be acted upon directly from the main heat exchanger by a lower temperature. Also, the advantage is achieved that the panel heat exchangers in the cooling operation of the air-conditioning system, may also be used for cooling.
