BRIEF SUMMARY
FIELD OF THE INVENTION

The invention relates to an outflow nozzle of a heating and/or air-conditioning system, in particular for a motor vehicle, according to claim 1.


BACKGROUND OF THE INVENTION

An outflow nozzle for a heating and/or air-conditioning system for the interior space of motor vehicles is known from EP-A3-0 210 548. In connection with said system, a separate control button for adjusting the horizontal and vertical direction of flow of the stream of air passing through the outflow nozzle is adjustably arranged in the center of the front side.


SUMMARY OF THE INVENTION

According to the problem of the present invention, the objective is to make it possible, on the one hand, to deflect in a defined way the stream of air exiting from the outflow nozzle, with simple and clear controllability and, on the other, to permit design possibilities for the front of the outflow nozzle that are independent of any particular arrangement of control elements, combined with simple manufacture and installation as well as a compact design. Advantageous further developments of the invention are the subject matter of the subsidiary claims.
By jointly using in accordance with the invention the quickly pivotable front baffle itself as a control element for the deflecting fins to be set to a certain position of swivel behind the front baffle, it is possible to dispense with special front-side control elements and to consequently design the front baffle on purely design considerations without its own flow setting. Usefully, for adjusting both horizontal and vertical flow characteristics of the stream of air, provision is made for a first array of deflecting fins and a second array of deflecting fins, whereby the swivel axes of the deflecting fins of the one array of deflecting fins are substantially perpendicular to the swivel axis of the other array of deflecting fins. The adjustment of the two arrays of deflecting fins by the adjusting element of the front baffle itself can be accomplished in this case in a particularly simple way by associating a first plane of swivel of the front baffle with one array of deflecting fins, and a second plane of swivel of the front baffle with the other array of deflecting fins, the latter plane usefully being perpendicular to the former, whereby in the way of a gimbal mounting of the front baffle relative to the housing of the outflow nozzle, the front baffle is concentrically swinging in the first plane swivel around an axle supported in the nozzle housing, and in the second plane of swivel, the axle itself, is capable of swinging with the front baffle relative to the nozzle housing.


BRIEF DESCRIPTION OF THE DRAWINGS

The invention as well as further advantageous developments of the invention are explained in greater detail by reference to the exemplified embodiments schematically shown in the drawing, in which:
FIG. 1 shows in a perspective, exploded view the essential components of an outflow nozzle according to the invention;
FIG. 2 shows the array according to FIG. 1 after it has been assembled; however, without the front baffle and the front baffle housing;
FIG. 3 shows the array according to FIG. 1 partly assembled, with a first array of deflecting fins and a first coupling rod, as well as with a second array of deflecting fins and a second coupling rod;
FIG. 4 shows the array according to FIG. 1 partly assembled, with only the second array of deflecting fins; and
FIGS. 5 to 8 each show in sectional view four adjustments of the horizontal deflecting fins of the first array of deflecting fins.
FIG. 1 shows in a perspective, exploded view an outflow nozzle having on the back side a nozzle housing DG, and on the front side a front baffle F in a front baffle casing FG. In the front baffle casing FG, the horizontal fins L1; L2 are pivot-mounted in a first array of deflecting fins, and the vertical fins L3 to L6 are pivot-mounted in a second array of deflecting fins, the latter fins being arranged behind the first array of fins, said deflecting fins being capable of swinging r
