Definitions

  • the invention relates to lighting devices or signaling for a motor vehicle.
  • a signaling device comprising a housing, a transparent glass and a seal deposited by extrusion around the ice.
  • This joint forms a bead intended to come into contact with the bodywork of the vehicle after mounting the device, and to be compressed to some extent to ensure the air, water and dust tightness between the body and device.
  • the seal is visible from the exterior of the vehicle so that the shape, dimensions and color of the joint allow to realize style effects.
  • the seal is deposited on one side external plane of an edge of the ice extending in periphery of a main wall of the ice.
  • the face external of the seal is in continuity with the external face of the border.
  • edge and main wall of the ice form an edge, the joint extending a short distance from this edge, projecting from the flat face of the border. It follows that if an external element comes into contact with the main wall of the ice and runs along it up to the joint, this element comes into abutment and bears on the joint and can help tear it off. Such an event may occur during the manufacturing of the device or when it is mounted on the vehicle, or when use of the vehicle.
  • An object of the invention is to provide a device lighting or signaling to limit the risk of the seal tearing off on contact with an element external.
  • the glass has a transverse profile having two generally parallel zones between them and offset from each other according to a direction parallel to a thickness of the glass, the seal being applied against one of the zones so that its face external extends in the extension of the other zone.
  • the ice has a groove in which extends the joint.
  • the ice includes a border extending around the main wall, the groove extending to a junction of the wall and the border.
  • the ice includes a border extending around the main wall, the joint having a face extending in the extension of a face of the border.
  • the ice includes a border extending around the main wall, the joint covering at least one end portion of the border opposite the ice, from this end.
  • the seal includes a lip.
  • the lip can flex over a large amplitude when mounting the device on the vehicle. We can therefore make up for significant play and tightness is insured in all cases.
  • the seal is attached to the ice and allows for style effects. So we provide a lighting or signaling device comprising a joint allowing style effects and allowing catch up with manufacturing and assembly games even when they are important.
  • the lip is locally inclined relative to the main wall of the ice.
  • the lip extends in the direction opposite the main wall of the ice.
  • the seal is overmolded on the ice cream.
  • the device comprises a housing to which the glass is attached, the joint extending at a distance of the case.
  • Figure 1 shows a lighting device or headlamp for motor vehicle, conforms to the invention. It includes a case 2, intended to carry one or more bulbs not shown, and a glass transparent 4.
  • the housing 2 and the glass 4 are each made of molded plastic.
  • Plastic material ice 4 may be a polycarbonate or a polymethyl methacrylate.
  • the ice has a wall main 6 of generally planar rectangular shape having an outer face 7 and an inner face 9 and having a slight convexity.
  • the wall 6 is intended to extend in a generally vertical direction, and to be crossed by the light beam of the bulb (s).
  • the glass has a locally flat profiled border 8 disposed at the periphery of the wall 6.
  • the border 8 extends from the wall 6, on the side opposite the convexity, in being inclined locally relative to the wall.
  • the border extends towards the rear of the device, towards the right in Figure 1.
  • the border 8 has a face internal 10 and an external face 12.
  • the glass 4 is fixed to the case 2 in a sealed manner. For this, the song of the free end of the border 8 is welded to the edge of the end of the wall of the housing.
  • the projector has an elastomer seal 14 which can be a synthetic rubber, extending to outside the device.
  • the glass 4 has a transverse profile, externally, at the junction between wall 6 and edge 8, a profiled groove 16.
  • the groove 16 has a bottom having in transverse profile two inclined zones one in relation to the other. Each bottom area is generally parallel to an area 17 of the respective profile of the external face 20 and of the border 8. Each zone 17 is contiguous to the throat and offset from the area associated bottom in a direction parallel to a thickness of ice.
  • the gasket 14 includes a base 18 which extends into this gorge and completely fills it.
  • a external face 20 of the base, adjacent to the wall 6, extends in continuity and in the extension of the external face 7 of the wall. So when an object runs along wall 6 to seal 14, it reaches the seal without come to a stop on this one.
  • Another external face 22 of the base, adjacent to border 8 extends in continuity and in the extension of the external face 12 of the border.
  • the outer face 7 of the ice presents a brutal break in slope realizing an angular point in profile. This constitutes a stall in the wall profile and it facilitates the realization of a precise and regular junction between the glass and seal. It is the same at the junction between the outer face 22 of the base and the outer face 12 of the border.
  • the seal 14 further comprises a thin lip 24 inclined locally relative to the wall 6.
  • the lip extends opposite the external face 22 of the base and look of the outer face 12 of the border. Lip 24 is locally parallel to border 8 and extends to distance from it.
  • the lip has an external face extending in the extension of the external face 20 of the base. Lip 24 generally extends rearward of the device towards the housing 2 and towards opposite the wall 4. This lip 24 is sufficiently thin to be flexible.
  • the joint 14 extends at a distance of the case.
  • the area of attachment of the seal 14 to the glass 4, namely the throat, extends away from the area of fixing the glass 4 to the housing 2.
  • the projector is manufactured using a process including the following steps. We mold the case 2. Then, we mold the ice cream 4. We overmold the joint seal 14 on the ice alone. This overmolding is done either in the ice making mold if this is provided in order to be able to change the configuration at this end, either in a specific mold. Overmolding of joint is quick to perform and provides a fixation of good quality of the glass seal.
  • the lip 24 When mounting the device on the vehicle, the lip 24 abuts by its external face against body elements 26 adjacent to the periphery of the device, and flexes elastically towards the device in contact with them. Lip 24 can be bend over a large amplitude. She allows to make up for weak manufacturing and assembly clearances or important concerning the device or these elements of body 26, while ensuring airtightness, water and dust with these body parts. We reduces noise, especially hissing noise when rolling.
  • the seal 14, in particular the lip 24, is visible from outside the vehicle, which allows style effects.
  • the end of the wall of the housing 2 in contact with the glass 4 has an extra thickness in which is formed a groove 28 open towards the edge 8.
  • the end of the border is received in this groove and there is fixed by interposing a layer of adhesive 30 between the internal face of the groove 28 and the edge 8.
  • the glass 4 has on its internal face 9 convex profiled gadroons with cylindrical profile. These gadroons perform a modification of the light beam as it crosses the ice cream.
  • the glass has a rigid lip 32 extending to from the internal face 9 projecting therefrom level of border 8, in direction opposite to the wall main 6, towards the rear of the device. This lip allows the fixing of the glass 4 to the housing 2 in a non- shown in detail.
  • the ice has only a half-groove 16 on the main wall 6.
  • the bottom of the half-groove is generally parallel to the area 17 of the external face contiguous to the half-groove, and offset in transverse profile with respect thereto according to a direction parallel to the thickness of the ice.
  • Gasket extends into the half-throat.
  • the external face 20 of the seal extends in the continuity and extension of the external face 7 of the main wall 6.
  • the seal 14 covers the entire border 8 and extends continuously from the wall main 6 ice beyond one end free rear of border 8 opposite the wall main 6 by covering the ice over this whole area and being in contact with the external face 12 thereof.
  • the seal 14 is here devoid of a lip.
  • the face outer 20 of the joint extends continuously from the wall main 6 of the ice to the free end 34 of the joint disposed beyond the free end of the border 8.
  • This external face 20 is generally parallel to the inner face of the border.
  • the seal 14 is intended for come into contact with a body element by its external face 20.
