Abstract

Der Scheinwerfer für Fahrzeuge weist einen schalenförmigen Reflektor (1) auf, zwischen dem und einer Linse (3) eine Blendenwelle (4) angeordnet ist. Die Blendenwelle (4) ist mit einem Antriebsmittel (5) gekoppelt, durch welches die Blendenwelle (4) um eine horizontale und quer zur optischen Achse (6) verlaufende Drehachse (7) in mehrere Drehstellungen verstellbar ist. Die Blendenwelle (4) ist in einer nach oben geöffneten Aufnahmerinne (9) eines unterhalb der Blendenwelle (4) verlaufenden Abschatters (8) angeordnet. An der Aufnahmerinne (9) ist die Blendenwelle (4) und ein Antriebsmittel (5) für die Blendenwelle (4) gehaltert.

Figure 00000001
The headlight for vehicles has a bowl-shaped reflector (1), between which and a lens (3) an aperture shaft (4) is arranged. The diaphragm shaft (4) is coupled to a drive means (5), by means of which the diaphragm shaft (4) can be adjusted in several rotational positions about a horizontal axis of rotation (7) extending transversely to the optical axis (6). The diaphragm shaft (4) is arranged in an upwardly open receiving channel (9) of a shader (8) running below the diaphragm shaft (4). The aperture shaft (4) and a drive means (5) for the aperture shaft (4) are held on the receiving channel (9).
