Abstract: A discharge nozzle has directional blades which can be swivelled about a swivel axis running parallel to the discharge-side front edge of a housing. The blades are swivelled by means of a coupling part, providing the directional blades with a common orientation. Diffused air flow through the discharge nozzle is selectively provided by diffusing insert blade segments which are insertable between the directional blades. The diffusing blades are part of a rigid diffusing grid, which is at least partially insertable from the back side of the directional blades between these blades and which is guided in a sliding manner in the nozzle housing by means of a rotary control button having a spiral guideway.

Abstract: A passenger car includes an arrangement for ventilating the passenger space with a wall-less channel with focused air flow to an interspace between a vehicle roof and an air-permeable roof lining. The air flow reenters the passenger space in distributed form to ensure with simple means a uniform air distribution over the entire exit area of the roof lining. The arrangement provides a focused air flow passing from the vehicle roof through the roof lining into the interspace in the sense of rebounded airflow distributed to all areas of the interspace. The focused air flow appropriately issues from a throw nozzle on a center console between front seats of a passenger car and impinges on an air entry region of the roof lining which has increased air permeability but which may not be readily visible.

Abstract: Starting with an outlet nozzle having directional louvers which are mutually slaved by a coupler in the region of their air-intaking back edge and are respectively able to swivel around a swivel axis which runs parallel to the front edge on the outlet side, a further increase of comfort can be achieved by means of an additional diffused setting of the directional louvers with simple means of small construction, whereby the directional louvers are guided in the region of their back edges by those types of crank guideways for the directional louvers in a horizontally and vertically guided crank carriage. The directional louvers are guided in a first setting of the crank carriage into a parallel directed airstream setting with the ability to swivel parallel to each other. During a horizontal movement of the crank carriage, the louvers are correspondingly guided into the respective diffused-flow setting by their respective crank guideways.

Abstract: An air outlet includes an inner discharge zone (3) and an outer discharge zone (4) surrounding the inner discharge zone in the shape of a ring. Both discharge zones are subdivided into several air guide ducts (9) by air baffles (8). The air baffles (8) of the discharge zones are inclined relative to the axis (10) of the air outlet (1). The air baffles of the one discharge zone (3) are slanted in the opposite direction of the air baffles of the other discharge zone (4).

Abstract: An air outlet having a housing with stationary and swivelling lamellae which are arranged to influence air circulation. the stationary lamelae are arranged parallel to each other. The swivelling lamellae are pivotally supported in the housing about their respective swivel axis which are parallel to each other and perpendicular to the stationary lamellae. Each swivelling lamella includes first and second cooperating partial lamellae, each of which includes at least one lamellar tongue. Each tongue of the first partial lamella is positioned adjacent to a tongue of the second partial lamella such that the tongues are arranged to alternate with each other and operatively associate a respective swivelling lamellae with stationary lamellae. The first and second cooperating partial lamellae of each swivelling lamella are coupled to each other to permit independent displacement of each partial lamella so that the outlet may be adjusted to diffuse the air passing therethrough.

Abstract: An air outlet (1) includes a housing (2) with vanes that swivel together in the housing. The vanes consist of plates (3 to 7), which, in the closed position of the plates, abut against each other with their longitudinal edges. Each plate is provided with several duct-type openings, the axes of which form an angle of 30.degree. to 60.degree. with the plate surface. In the closed position of the plates, the air outlet thus obtains an additional jet characteristic.

Abstract: A system for ventilating the passenger compartment of an automotive vehicle comprises an air discharge nozzle located at approximately the center of the vehicle's dashboard along a lower edge of the windshield. The nozzle ejects a broad air stream upwardly along an inner surface of the windshield. The air stream is received by a funnel located along the upper edge of the windshield between the windshield and the rearview mirror. The interior of the funnel communicates with an interspace defined by the vehicle roof and a roof lining. The interspace is closed along the rear window and is provided with air deflection elements for steering a portion of the inflowing air stream laterally towards the sides of the vehicle. The roof lining is provided above the passenger seats with a multiplicity of openings having adjustable cross-sectional areas for varying the amount of air entering the passenger compartment through the openings.

Abstract: A ventilating system for a motor vehicle comprises an air mixing and filtering assembly including a housing defining an air mixing chamber, the housing including a first air inlet port for conducting into the air mixing chamber air from the external environment, a second air inlet port for conducting from the passenger compartment of the motor vehicle air to be recirculated and an outlet port for conducting a composite air stream to the passenger compartment. The assembly includes a filter disk which is pivotably mounted to the housing, the filter disk simultaneously serving as a means for setting the proportions of external air and recirculated air. The filter connection piece forms a part of the housing defining the air mixing chamber.
