Definitions

  • the present invention relates generally to motor vehicle headlights fitted with an intermediate mask.
  • a projector conventionally comprises a lamp cooperating with a mirror, for example of the parabolic type to form a beam, and a front closing glass.
  • Such a mask can be provided with reliefs such as streaks, prisms, etc. intended to conform the beam leaving the mirror to cause it to meet the photometric requirements, in particular as regards cutting and width.
  • the mask applied, by suitable edges, against the internal face of the lens in the region of its periphery, in order in particular to avoid the presence of dark zones at the level of this periphery between the lens and the mask.
  • the solution currently adopted for fixing the mask consists in clipping it, using elastic tabs, onto the projector housing in the region where the lens base is fixed on this housing, so that the aforementioned flanges are in support against ice.
  • the present invention aims to overcome these drawbacks of the prior art. To this end, it provides a motor vehicle headlamp, of the type comprising a light source, a mirror, a closing glass and an optical and / or styling treatment element intended to be supported both on the housing and on the lens in a peripheral region thereof, characterized in that said element comprises, in at least two opposite regions, two mounting lugs extending from the element in a divergent manner towards the rear of the headlight, in that that there are provided in homologous regions of the housing two housings for said mounting lugs, also oriented in a divergent manner so that substantially no stress is applied to the element by said mounting lugs when they are engaged in said housing.
  • a headlamp which comprises a housing 10 closed at the rear by a windscreen 10 'and at the front by a closing glass 30.
  • the housing houses a lamp 20 which cooperates with a reflector or mirror 18.
  • a mask intermediate 40 which may for example include prisms, ridges, or the like intended to work the beam.
  • the mask 40 comprises in the region of its upper edge a first tab 41, extending forward for a short distance and intended to bear by its free end in a notch 31 formed in the upper region 30a of the ice base .
  • Another tab 42 extends rearwardly in the extension of the tab 41 and is intended to be inserted in a notch 11 formed by appropriate conformation of the housing in this region.
  • the legs 41 and 42 are in this example oriented approximately horizontally.
  • the housing 10 comprises in this region a wall part 12 slightly inclined in an ascending direction from the rear to the front, where it joins the part defining the notch 11.
  • a part 44 forming an embellishment and extending essentially horizontally both backwards and forwards with respect to the mask. From the free front end of this part extends, generally towards the rear and downwards, a connecting part 45.
  • this connecting part From the rear end of this connecting part extend, generally horizontally and towards the rear, two lugs 46 intended to be applied against the upper surface of a lower wall 13 of the housing 10.
  • leg 48 is provided which is shorter and wider than the legs 46, 47, which extends forward in the extension of the two legs 46 and the free front edge of which is intended to bear in a notch. 32 formed in the lower region 30b of the ice base.
  • the projector as described above behaves as follows: first of all, the reflector 18 having been placed and mounted in the housing 10, the mask is put in place from the front opening of said housing, the glass 30 not yet being mounted. It should be noted that, thanks to the divergence of the tabs 42, 47 which maintain the mask in the housing, this mounting of the mask is carried out by temporarily exerting a bending stress on the mask, so that the free ends legs 42, 47 come opposite the entrances of the notches 11, 14. Then, by exerting on the mask a push in the direction of the reflector, these legs engage in the notches, until the stresses in the mask are released.
  • the glass 30 is then placed on the front opening of the housing, with the interposition of a seal. During this positioning, the tabs 41, 48 come to engage in the notches formed in the corresponding locations of the ice base.
  • the legs 43, 46 are intended to induce elastic return forces in the upper and lower regions of the mask 40 respectively in the direction of the glass, to ensure under all conditions an effective application of the legs 41, 48 against the glass. This makes it possible in particular to compensate for position differences due to manufacturing tolerances, as well as displacements due to thermal expansions.
  • the tabs 42, 43 on the one hand, and 46, 47 on the other hand act as a sort of pliers which come to grip in an elastic manner homologous parts of the housing, with a spacing which can vary according to the relative position of the mask and the housing.
  • the tab 42 will sink more or less into the associated notch 11, but the cooperation of the tab 43 , which has a certain inherent elasticity, and of the inclined wall 12, will exert on the upper region of the mask a force tending in all cases to apply the tab 41, with a force always moderate, against the ice base.
  • the tab 47 will sink more or less into the housing 14, while the tabs 46, inclined relative to the tab 47 and applied elastically against the wall part 13, ensure the application to the lower region of the mask with a moderate force to press the tab 48 against the region opposite the ice base.
  • the arrangements of the present invention make it possible to cope with uncertainties or variations in positioning between the glass and the housing of a few millimeters along the axial direction of the projector.
  • the invention described above relates to the positioning of a mask interposed on the path of light radiation, it is understood that it can also be applied in particular to the positioning of a hubcap or the like extending only in the peripheral region of the housing, intended mainly to ensure continuity of appearance of the headlight, switched off, from its lens to the bottom, as described in particular in document FR-A-2 611 859 in the name of the Applicant.
