  • the side wall has on the outside a peripheral edge section pointing in the mounting direction. Fixing elements pointing in the direction of attachment protrude from the side wall, which inside the collar in corresponding recesses of the reflector intervene to the retaining ring in a certain rotational position to the reflector hold.
  • Retaining springs are attached to the side wall, which hold the lamp with press their base against the reflector. From the inside of the wraparound Edge section of the retaining ring protrude barb-like expansion elements, which point against the mounting direction of the retaining ring and in the Claw the outer surface of the collar. It is disadvantageous that the Spreading elements after placing the retaining ring up against the of the End face of the collar formed stop surface more or less far can spring back, and the exact predetermined by the stop surface Position of the retaining ring is to the opening of the reflector receiving the lamp no longer exist. This ensures a secure mounting of the lamp with the Retaining springs of the retaining ring are no longer guaranteed. Besides, that can Fixing element of the retaining ring, which is in a recess in the reflector engages, disengage, and the ring is in an undesired position rotatable.
  • DE 34 32 445 C2 is a holder for a lamp Vehicle headlights have become known, in which two from spring plate manufactured holding elements on opposite sides of a lamp receiving opening of the reflector are clamped. To the Holding elements are supported by a U-shaped retaining spring, which holds the lamp presses against the peripheral edge of the opening of the reflector. The assembly the two holding elements made of spring sheet metal are cumbersome and time consuming.
  • the object of the invention is that described in the preamble of claim 1 Holding a lamp in an opening of a reflector To design vehicle headlights so that the retaining ring according to his Assembly, even if the spreader stars a little after putting on the retaining ring spring back, remains on the stop surface or near the stop surface runs to a precise position of the retaining ring to the lamp receiving Obtain opening of the reflector.
  • This object is achieved according to the invention solved in that the stop surface by at least two Stop elements of the reflector is determined, between which at least a barb-like expansion element is arranged, which consists of a inner edge section of a side wall running transversely to the mounting direction a retaining ring made of sheet metal is cut free.
  • the outside dimensions of the retaining ring can vary be when the stop elements outside the collar to the back of the reflector are formed and the retaining ring surrounds the collar on the outside.
  • Stop elements are ribs formed on the back of the reflector usable, which with its wide side surface transversely to the neighboring The outer surface of the collar run. Such ribs are easy to demold and have no thickening towards the reflector, through which sink marks the reflection surface of the reflector can arise.
  • the retaining ring is very securely attached to the collar of the reflector when it is by internal tension forces, which between the expansion elements and the stop elements exist, abutting the stop elements is held.
  • the size of the internal tension forces depends on the Pressure forces of a mounting device with which the retaining ring between the Stop elements is pushed towards the reflector.
  • the retaining ring has a high torsional stiffness when the Spreading elements on the base of a clearance in the side wall on the retaining ring are connected and the side wall from the outside to a Main extension of the side wall extending edge section is surrounded. Of the Edge section can in or against the mounting direction of the retaining ring be directed.
  • the retaining ring can be manufactured inexpensively using the deep-drawing process, and the side surface of the side wall pointing counter to the mounting direction can serve as a contact surface for the mounting device.
  • the force of the expansion elements with which the expansion elements in the Claw surface of the collar is large enough to secure To achieve tightness of the retaining ring on the collar when the expansion elements run at an acute angle to the surface in which the side wall of the Retaining ring lies.
  • the expansion elements of the retaining ring claw very deep into the lateral surface of the Collar when it runs through her on the edge facing the collar Have free cutting existing degrees.
  • a headlight for vehicles has a plastic one bowl-shaped reflector (2), which in its apex area for Receiving a lamp (1) has an opening.
  • the lamp (1) is from the Back of the reflector (2) inserted into its opening and lies with one Base flange (18) on an outer edge region of the opening of the reflector (2).
  • the collar (3) borders with its inner side surface on the outer edge of the base flange (18) of the lamp (1) and thus serves as a threading aid for the lamp (1) their insertion into the opening of the reflector (2).
  • rib-like stop elements (8) on the back of the reflector (3) integrally formed, which with its wide side surfaces radially to the longitudinal axis of the Lamp (1) run.
  • the stop elements (8) point to the back of the Reflector (2) pointing side each have a stop surface (7) for one Retaining ring (4).
  • the stop surfaces (7) lie in an area to which the Longitudinal axis of the lamp (1) runs perpendicular.
  • the rib-like stop elements (8) have a wall thickness which is not greater than the wall thickness of the cup-shaped reflector (2).
  • the retaining ring (4) which is made of resilient, rests on the stop surfaces (7) Sheet is punched out.
  • the retaining ring (4) is placed on the collar until he with a side wall (4) on the stop surfaces (7) of the stop elements (8) is present.
  • the side wall (9) is at its outer edge from one against the Setting direction (5) of the retaining ring (4) directed edge section (10).
  • the side wall (9) has clearances (15) on its inner edge the base of which is designed as tongues of barb-like expansion elements (6) are connected.
  • the spreading elements (6) point counter to the direction of attachment (5) and run at an acute angle ⁇ to the surface in which the Contact surfaces (7).
  • the angle ⁇ is in the relaxed state of the expansion elements (6) preferably between 20 ° and 50 °.
  • the tongue-like expansion elements (6) are cut free in the mounting direction (5) from the inner edge of the retaining ring (4), thus on the edge (11) facing the collar (3) at the free end of the Spreading elements (6) remain one degree. With this degree (11) the claws barb-like expansion elements (6) in the outer surface of the collar (3).
