Definitions

the invention relates to a headlight for vehicles with a plastic manufactured bowl-shaped reflector, with a inside of the reflector arranged light source and with an aperture, which in the light exit direction seen after the light source is arranged, is made of sheet metal and at least one support arm with one composed of two parts has free end portion which engages in a reflector opening and the and the reflector opening tapers in the direction of insertion of the end section.
Such a headlight for vehicles is known from EP 0 636 821 B1.
the headlight cover is made in one piece from a sheet metal blank.
An annular diaphragm section of the diaphragm is in the light exit direction seen arranged after the light source and has a seam from which extends a double support arm to the outside.
the support arm points with its free end section against the light exit direction and is in a reflector opening formed by a hollow cylinder of the reflector used, which is closed towards the back of the reflector.
the double End section of the support arm consists of U-shaped in cross section Sections that lie together with their side faces and together form one Form a gutter open to the outside.
the U-shaped end section digs when pressed into the reflector opening with sawtooth-shaped edges into the inside of the reflector opening. This creates fine chips that can deposit on the decorative reflective surface of the reflector and can be seen through a smooth lens.
the support arm engages with the sawtooth-shaped edges of its end section Flattening the inside of the reflector opening and is due to one of the Hollow cylinder of the reflector formed stop so that the aperture after Your assembly takes a precise position to the reflector.
a middle section of the double plate-shaped End section forms a cavity formed by two indented grooves is.
the channels or the cavity tapers in the direction of insertion Support arm.
the support arm is with the end section having the cavity self-locking inserted in the reflector opening and in this position angled free ends on the back of the reflector securely in the reflector opening held.
the reflector opening corresponds to the plate-shaped End section a rectangular cross section with an enlarged middle section. Only through the rectangular cross section of the reflector opening is the cover takes one and the same position after assembly to the optical axis of the reflector.
the reflector opening is because of it rectangular shape disturbing through a smooth lens to see.
the service life of the reflector tool is also reduced because of the narrow areas of the rectangular reflector opening.
the object of the invention is that described in the preamble of claim 1 Design headlights for vehicles so that the bezel too is then securely fixable in the reflector opening if the Aperture in the reflector opening receiving the end section of the support arm there is no material abrasion and the reflector opening remains the size of the can be adapted in the end portion used in the reflector opening and the aperture is aligned with the optical axis of the reflector after assembly is.
the end section consists of two half-shells forming a cavity, the seams of which run in the direction of insertion, one of which seam from radial to internally directed edge sections is formed and the other interface through a flattening of the hollow end section extends to which a surface section runs adjacent to the inside of the reflector opening. Because the Edge sections are directed inwards at one interface and at the the other face, the end faces of the half-shells lie bluntly in front of each other, there can be no abrasion in the reflector opening. Due to the conical design the outer surface of the end section is a self-locking tight fit of the support arm in the reflector opening.
the Reflector opening is a through hole from which on the back of the Reflector of the hollow end portion with at least one to the outer edge area the free end deformed towards the reflector opening, the support arm with a contact surface in the direction of insertion on a stop surface of the reflector.
the conical end section lies in this position its radial spring force with a large preload on the inner surface the conical reflector opening.
the free ends are punched out of the end section so that after bending under Apply bias to the edge area of the reflector opening.
the cover and its support arm has a high rigidity when the cover consists in one piece of a shaped sheet metal blank, one around the optical Annular aperture section of the reflector runs around the axis with a seam, from the edges of sheet metal sections to the outside protrude, lie flat against each other and form the support arm and continue the two half-shells of the hollow end section are in the flat against each other
Extend sheet metal sections in the area of the double sheet metal sections taper together against the direction of insertion and into the merging sheet metal sections lying flat against one another.
the conical end section together with the double sheet section high rigidity.
the headlight shown in the drawing has an existing plastic bowl-shaped reflector 1 with one in the apex region of the reflector 1 introduced opening for receiving a light source 2.
the light source 2 can be formed by an incandescent lamp or a gas discharge lamp his.
An aperture 3 is arranged after the light source 2 in the light exit direction, which emerges directly from the light source 2 and otherwise the oncoming traffic shields dazzling rays of light.
the aperture 3 has an optical Axis of the reflector 1 concentric annular aperture section 16 on.
the annular diaphragm section 16 has in the lower region a seam 17, from which one of two plate-shaped Sheet metal sections 18 double support arm 4 extends downwards.
the free one End section 5 of the support arm 4 goes into the plate-shaped sheet metal sections 18 about and is formed by two half-shells 8, one of which is towards the free end of the support arm 4 form a tapered cone.
the conical end section 5 runs in its longitudinal extent parallel to the optical axis of the reflector 1 and is in the direction of insertion 7 in a conical end portion 5 corresponding executed conical reflector opening 6 of a hollow cylinder 20 of the Reflector 1 introduced.
the hollow cylinder 20 protrudes from the front of the reflector as well as the back of the reflector.
the forming the end section 5 Half-shells 8 extend to the plate-shaped sheet metal sections 18 and taper in the area of the sheet metal sections 18 against the direction of insertion 7.
the two half-shells 8 border on an upper and a lower one Interface 9 or 10 to each other.
At the near point 9 lie radially inwards directed arcuate edge sections 12 with their free edges towards each other, the end faces of the edge sections 12 running in one surface.
the another seam 10 runs centrally through a flattened portion 11 of the end section, which corresponds to a correspondingly large flattening of the inside of the Reflector opening 6 is present.
the plate-shaped sheet metal sections 18 have opposite sides of the end section 5 each in the direction of insertion directed contact surface 14, which after insertion to one of an end face of the hollow cylinder formed stop surface 15 strikes. After that lies the end section 5 under prestress on the inner surface of the reflector opening 6 and is self-locking.
the end section 5 is always with a large clamping force on the inner surface of the reflector opening 6 because of the end portion because of the inwardly curved edge portions 12 radially resilient is compliant.
the end section 5 projects with its free end 13 on the Back of the reflector 1 out of the reflector opening 6.
the free end 13 is formed by two opposing lobes that oppose each other Are bent towards the edge region of the reflector opening 6, on the Border area under prestress and the tight fit of the end section 5 secure in the reflector opening 6. In FIG. 3, the free ends 13 are 13 ' shown before bending.
