Definitions

  • the invention relates to a lamp unit for motor vehicles with the features of the preamble of claim 1.
  • Such a lamp unit is known from EP 0 597 763 A1.
  • the location where the approach is located is fixed. It should be the place where the ventilator works best.
  • the location at which the ventilation body works optimally varies.
  • the invention has for its object to provide a lamp unit of the type mentioned, in which it is possible with simple means to arrange the ventilation body at an optimal location even if this location changes, for example in the context of vehicle development or from type to type .
  • the ventilation body Due to the clip fastening of the ventilation body, it is easily possible to attach it to any desired location on the luminaire housing. It is only necessary to create an opening within the lamp housing into which the ventilation body can be inserted. By a suitable choice of this opening, it is then possible to arrange the ventilation body in the optimal position. This location can change as described or be selected differently.
  • the clipping is designed to be detachable, it is also possible to vary the location of the ventilation body within a cover cap. Any existing free opening is then only to be closed in a suitable form.
  • FIG. 1 shows a cover cap 1 of a housing, not shown, for a lamp unit of a motor vehicle, in which at least one headlight, also not shown, is contained.
  • the cap 1 is arranged on the back of the headlight and is located in the engine compartment of the motor vehicle, also not shown.
  • a horizontal extension 2 of the cap 1 is provided with an opening 3 into which a ventilation body 4 is inserted.
  • the ventilation body 4 consists of two parts, namely an outer part 5 and an inner part 6, which are inserted into one another.
  • the inner part 6 has a fork-shaped cross section at its end facing the opening 3. It reaches behind the covering cap 1 with a partial fork 7 and sits on the shoulder 2 with its collar 8.
  • An O-ring 9 sits between the collar 8 and the outside of the cover cap 1 as a seal.
  • the ventilation body 4 contains a filter 10, furthermore a labyrinth 11 and an inlet grille 12.
  • the attachment of the ventilation body 4 is possible with a suitable design of the cover cap 1 or the headlight housing wherever a corresponding approach 2 is provided.
  • the approach closed during the production of the cover cap is only to be provided with an opening corresponding to the opening 3 by means of a corresponding tool.
  • the ventilation body 4 is to be inserted into the opening and clipped into it.
  • the cover cap or the headlight housing contains several such approaches, the location at which the ventilation body and possibly several such ventilation bodies are to be provided can be varied.
  • the effect of the Ventilation body 4 then optimal.
  • the entry of dirt particles and the like into the interior of the lamp unit is also permanently prevented, while at the same time ventilation is possible without hindrance.
  • a valve 12 which contains a buoyancy body 13.
  • the valve 12 is provided within the ventilation body 4 'at the transition from the vertical to the horizontal passage. This makes it possible to prevent moisture from entering the interior of the luminaire unit even when moisture enters the ventilation body.
  • the buoyancy body then reliably closes the valve opening 12 '.
  • the additional arrangement of a filter for example in the figure below the valve body and also a labyrinth and an inlet grille, as shown in FIG. 2, is not shown but is readily possible. This makes it possible to seal the luminaire unit under all operating conditions and, on the other hand, to ensure adequate ventilation.
