Abstract

The headlight has its scatter window fitted into a frame fixed to the vehicle's bodywork. The incandescent lamp has a reflector and is fixed to the frame via a toroidal bellows. The bellows have an inner section with a ring held to the reflector by screws and an outer section with a lip that fits into a slot in the frame. Spring positioning flaps on the frame rest on the step of the lip and hold the bellows in position. The two sections of the bellows overlap so that the headlight has a relatively small axial length. The bellows are simple and cheap to fabricate.

Description

Schelnwerf er für KraftfahrzeugeHe throws for motor vehicles

Stana der Technik Die Erfindung geht aus von einem Scheinwerfer für Kraftfahrzeuge nach der Gattung des Hauptanspruchs. Ein der artiger Scheinwerfer ist bereits aus der DE-PS 963 837 bekannt, bei dem ein nach dem Zieharmonikaprinzip wirkender Faltenbalg die mit der Karosserie fest verbundene Streuscheibe und den verstellbaren Reflektor verbindet. Die maximale horizontale Verstellbarkeit bestimmt die horizontale Justierung des Scheinwerfers, und die maximale vertikale Verstellbarkeit ergibt sich aus der Summe der Vertikaljustierung und der Leuchtweiteregelung Der Balg muß darüber hinaus noch das von Streuscheibe und Reflektor gebildete Scheinwerferinnere gegenüber der Außenatmosphäre abdichten.Stana der Technik The invention is based on a headlight for Motor vehicles according to the species of the main claim. One of those spotlights is already known from DE-PS 963 837, in which a according to the accordion principle acting bellows the diffuser firmly connected to the body and the adjustable reflector connects. The maximum horizontal adjustability is determined the horizontal adjustment of the headlight, and the maximum vertical adjustability results from the sum of the vertical adjustment and the headlight range control Der The interior of the headlight formed by the lens and reflector must also be bellows seal against the outside atmosphere.

Da die Falten des Faltenbalges zwischen dem Reflektorfuß und dem Streuscheibenflansch angeordnet sind, vergrößert sich hierdurch die axiale Einbautiefe des Scheinwerfers.Because the folds of the bellows between the reflector base and the lens flange are arranged, this increases the axial installation depth of the headlight.

Vorteile der Erfindung Der erfindungsgemäße Scheinwerfer mit den Merkmalen des Hauptanspruchs hat gegenüber dem gewürdigten Stand der Technik den Vorteil, einer niedrigen Bauhöhe weil sich die beiden Balgabschnitte in axialer Richtung überlagern. Dadurch, daß die Wandstärke des Rollbalges dünner und die gestreckte Länge kürzer ist als diejenige des Faltenbalges, ergibt sich eine gewisse Materialersparnis. Die unkompliziertere Gestalt und das einfachere Entformen des Rollbalges aus der Herstellform sind weitere, in der Großserienfertigung beachtliche Vorteile.Advantages of the Invention The headlight according to the invention with the features of the main claim has the advantage over the recognized state of the art, a low overall height because the two bellows sections are in the axial direction overlay. Because the wall thickness of the rolling bellows is thinner and the stretched one Length is shorter than that of the bellows, there is a certain material saving. The uncomplicated shape and the easier removal of the rolling bellows from the Manufacturing form are further advantages that are considerable in large-scale production.

Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen beschrieben. Mit der Ausgestaltung des Scheinwerfers nach Anspruch 2 wird eine materialsparende Befestigung des Rollbalges am Rahmen geschaffen. Eine rüttelsichere, einfache Befestigung des Rollbalges wird mit den Merkmalen des Anspruchs 4 erreicht. Die Weiterbildung des Scheinwerfers nach Anspruch 5 ergibt eine sichere Befestigung des Rollbalges am Reflektor.Advantageous further developments of the invention are set out in the subclaims described. With the design of the headlight according to claim 2, a material-saving Attachment of the roll bellows to the frame created. A vibration-proof, simple attachment the rolling bellows is achieved with the features of claim 4. The further training of the headlamp according to claim 5 results in a secure attachment of the rolling bellows on the reflector.

Zeichnung Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und in nachfolgender Beschreibung näher erläutert. Es zeigen Fig. 1 das Ausführungsbeispiel in teilweisem Axialschnitt und verkleinertem Maßstab; und Fig. 2 die abschnittsweise Ansicht nur des Rahmens in Blickrichtung II gemäß Fig. 1.Drawing An embodiment of the invention is shown in the drawing and explained in more detail in the following description. 1 shows the embodiment in partial axial section and reduced scale; and Fig. 2 shows the sectional view of only the frame in viewing direction II according to FIG. 1.

Beschreibung des Ausführungsbeispieles Ein Scheinwerfer für Kraftfahrzeuge in Fig. 1 hat im wesentlichen einen an der nicht gezeichnetenFahrzeugkarosserie befestigten Rahmen 10 aus Druckguß, eine in diesem eingeklebte Streuscheibe 11, einen mit einer Glühlampe 12 bestückten Reflektor 13 und einen Rollbalg 14 aus elastischem Material.Description of the exemplary embodiment A headlight for motor vehicles in Fig. 1 has essentially one on the vehicle body, not shown fixed frame 10 made of die-cast, a diffuser 11 glued into this, a reflector 13 fitted with an incandescent lamp 12 and a rolling bellows 14 made of elastic Material.

Der Rollbalg 14 hat einen Außenabschnitt 15 mit einem radial nach außen abstehenden Wulst 18, einen Innenabschnitt 17 mit einem radial nach innen weisenden Ring 19 und einen beide Abschnitte verbindenden Rollbereich 16.The rolling bellows 14 has an outer portion 15 with a radially outwardly protruding bead 18, an inner section 17 with a radially inward pointing ring 19 and a rolling area 16 connecting both sections.

Im Rahmen 10 ist eine V-förmige Nut 20 ausgespart, deren Innenflanke 21 an fünf Stellen von jeweils einer Federzunge 22 unterbrochen ist. Diese steht vom Bereich 23 des Rahmens 10 ab und ragt annähernd parallel zur optischen Achse 24 in Richtung der Streuscheibe 11. Der Ring 19 des Rollbalges 14 liegt an der Außenseite eines Flansches 25 des Reflektors 13 an, und diese Lage sichert ein mittels Schrauben 27 befestigter Gegenflansch 26.A V-shaped groove 20 is recessed in the frame 10, the inner flank of which 21 is interrupted at five points by a spring tongue 22 each. This stands from the area 23 of the frame 10 and protrudes approximately parallel to the optical axis 24 in the direction of the diffuser 11. The ring 19 of the rolling bellows 14 is on the outside a flange 25 of the reflector 13, and this position is secured by means of screws 27 fixed counter flange 26.

Die abschnittsweise Frontansicht des Rahmens 10 in Fig. 2 zeigt dessen Bereich 23 mit der anschließenden, unterbrochenen Innenflanke 21 und die in der Unterbrechung 28 angeordnete Federzunge 22.The sectional front view of the frame 10 in FIG. 2 shows it Area 23 with the adjoining, interrupted inner flank 21 and in the Interruption 28 arranged spring tongue 22.

Der am Reflektor 13 befestigte Rollbalg 14 wird am Rahmen 10 folgendermaßen befestigt: Der Wulst 18 des Außenabschnittes 15 wird in die Nut 20 des Rahmens 10 eingeschoben, dabei werden die fünf Federzungen 22 nach außen gedrückt. Das Einschieben geschieht soweit, bis die Federzungen 22 radial nach innen zurückfedern, so daß sich jede Federzunge 22 an einer Schulter 30 des Wulstes 18 abstützt. Hierbei liegt der Wulst 18 am Nutgrund 29 der Nut 20 an. Das Lösen des Rollbalges 14 vom Rahmen 10 geschieht dadurch, daß man die fünf Federzungen 22 von der Schulter 30 des Wulstes 18 abhebt und den Außénabschnitt 15 des Rollbalges 14 aus der Nut 20 nach hinten schiebt.The bellows 14 attached to the reflector 13 is attached to the frame 10 as follows attached: The bead 18 of the outer section 15 is inserted into the groove 20 of the frame 10 pushed in, while the five spring tongues 22 are pressed outwards. The pushing in happens so far until the spring tongues 22 spring back radially inward, so that each spring tongue 22 is supported on a shoulder 30 of the bead 18. Here lies the bead 18 on the groove base 29 of the groove 20. The release of the rolling bellows 14 from the frame 10 is done by removing the five spring tongues 22 from the shoulder 30 of the bead 18 lifts off and the outer section 15 of the rolling bellows 14 out of the groove 20 to the rear pushes.
