Definitions

  • the present invention relates to a headlamp for a motor vehicle and in particular to a technical improvement intended to improve the external appearance of the headlamps, that is to say of the visible part of the exterior of the vehicle.
  • the headlights of motor vehicles are designed so as to allow an adjustment of the orientation of the light beam, an adjustment generally achieved by making the reflector of the headlight movable relative to the surrounding parts of the vehicle.
  • the object of the present invention is to avoid the above drawbacks and to propose a headlamp having a uniform external appearance, in particular between the glass and the reflector.
  • the subject of the invention is a headlamp of the type with fixed glass and housing and with movable reflector, essentially characterized in that the transverse clearance existing between the reflector and the housing as well as the interior walls of the housing lying between the faces front of the housing and the reflector are masked by a converging sleeve internally coated with a layer of material of the same appearance as that covering the interior wall of the reflector, sleeve of which one end is fixed to the peripheral rim of the housing and of which the other end is free and comes flush with the interior wall of the reflector while providing sufficient axial clearance to allow pivoting of the reflector.
  • a motor vehicle headlamp mounted between the engine cover 1 and the front bumper 2, and comprising a diffusing glass 3 assembled by bonding to the peripheral rim 4 of a fixed housing 5.
  • a reflector 6 is capable of pivoting about a horizontal axis 7 to adjust in a known manner the orientation of the light beam delivered by the light source 8.
  • an intermediate piece 15 is interposed in the form of a convergent sleeve, one end 16 of which is connected to the peripheral rim 4 of the housing and the other end 17 of which remains free and is substantially flush with the extension of the internal wall 18 of the reflector for give an aspect of continuity.
  • the small dimensions of the sleeve 15 make it possible to envisage, under economic conditions, a coating of its internal surface 20 with a material if not of the same kind, at least of the same appearance as the coating covering the reflector. It may in particular be a layer of paint, a vacuum metallization, an electrolytic coating such as chrome plating or nickel plating, etc.
  • the sleeve 15 can be made of synthetic material, for example plastic or any other economical material such as stamped sheet metal.
  • the sleeve can be integrated into the housing and come directly from molding with it, as illustrated in FIG. 3.
  • the assembly can be made in two halves to facilitate the operation of demoulding.
  • the sleeve 15 When the sleeve 15 is manufactured separately from the housing, it is then attached to the latter (FIG. 4) and can be fixed by various conventional assembly methods such as screwing, riveting, snap-on, bonding etc. (straps 21 in Figure 4).
  • FIGS. 5 to 7 illustrate a preferred mode of assembly of the sleeve 15 on the housing 5 by means of lugs 22 coming from molding with the sleeve and engaging in corresponding notches 23 of the housing distributed regularly over the periphery of the two elements to to assemble.
  • Figure 6 thus comprises 8 fixing and centering tabs.
  • Figure 5 shows in exploded perspective a lower tab 22, extending at right angles to the inverted edge 30 of the sleeve.
  • This tab engages in the notch 23 formed in one of the wings of the U-shaped groove forming the rim 4 of the housing, intended to receive the edge of the diffusing glass 3 (not shown).
  • the notch gives rise to a setback 24 in excess thickness so that after engagement, the front face 25 of the tab is flush with the bottom 26 of the groove so as not to hinder the edge of the glass during assembly.
  • the assembly is immobilized by the bead of adhesive 27 which serves to fix the glass (FIG. 7).
  • the fixing lugs 22 are slightly longer than in the previous case and are locked elastically behind the lower wing 28 of the U-shaped groove, that is to say the opposite wing at the notch.
  • the notch 23 in Figure 5 is extended downward and opens through the lower wing 28 of the groove, perforated at 29 for this purpose.
  • This feature allows pre-assembly of the sleeve 15 by snap-fastening the tabs 22 on the housing, which then facilitates the handling of the parts for the operation of bonding the glass 3.
