WING PRESSER, PROJECTOR ASSEMBLY

AND BUMPERS.

GENERAL TECHNICAL AREA.

  The present invention relates to assemblies for vehicles, in particular motor vehicles, allowing the control of the geometries between the

  vehicle accessories and bodywork equipment.

  More specifically, it relates to assemblies capable of ensuring control of the geometry between the wings and the plastic bumpers of the

  motor vehicles and headlights.

STATE OF THE ART.

  The bodies of vehicles, in particular motor vehicles, have different elements or accessories. Among the possible accessories to be mounted on a bodywork, it is possible in particular to provide spotlights,

bumper and fenders.

  The headlamps are notably mounted on the front or rear of the

  vehicle for traffic lights, near fenders and bumpers.

  Part of the elements and accessories can be mounted on

  a support frame for all of the bodywork elements.

  During an industrial assembly process, the elements are

mounted on the carcass.

  Any industrial process leads to production dispersions. For example, it is difficult, if not impossible, to always make the same adjustment for mounting the parts, and in particular to control the geometry

  parts and accessories relative to each other.

  This precise assembly of the parts and accessories with respect to each other makes it possible to guarantee control of the play of appearance. For aesthetic questions, the parts must be situated substantially at the same level with one another for a user. So the

  vehicle body appears substantially reqlière.

  The control of the play of aspect must take into account the effects of the important thermal variations which the vehicles can undergo. In the case of parts and accessories made of different materials, each part or accessory will have its own expansion. There follows a change in the

  appearance games as a function of temperature.

  The control of aspect games must also take into account the

  effects of impact that vehicles may experience during use.

  The play of aspect can increase with the shocks undergone by the cars. The lower the play of appearance with the shocks undergone, the more the costs of

  repair after sale are low.

  The objective is therefore to reduce as much as possible the play of appearance as a function of the industrial assembly, variations in temperature, and

vehicle shocks.

  Several solutions have so far been proposed.

  It is thus possible to provide direct fixing piece by piece by screwing,

clipping or others.

  We also perform an indexing of the parts relative to each other by curling between the wings and the windows of the projectors

for example.

  Finally, we can use aspect joints that allow filling

  the play between the pieces in relation to each other.

  The foregoing techniques have drawbacks, however.

  First, direct room-to-room connections are expensive.

  In addition, in number of attachments added, they increase the weight as well

  that assembly times. Finally, they are more fragile in the event of impact.

  Consequently, they generate additional costs during after-sales repairs. Secondly, the curl type connections require an overmoulding on the headlamp lenses which restricts the freedom of form

  aesthetic, while generating a significant additional cost on the projector.

  The internal seal between the glass and the housing, as well as the horizontal adjustment of the headlight beam can be degraded in the event of

too great constraints.

  Third, appearance seals are expensive. They are moreover more often specific and difficult to industrialize when they are applied

  too late in development projects.

PRESENTATION OF THE INVENTION.

  The invention proposes to overcome these drawbacks.

  To this end, the invention provides an assembly for a vehicle, in particular a motor vehicle, comprising a wing of the vehicle, a headlight, characterized in that it further comprises presser means capable of pressing

  the wing on the headlight of the vehicle.

  The invention is advantageously supplemented by the following characteristics, taken alone or in any of their technically possible combinations: - it further comprises a bumper, the presser means being capable of pressing the wing and the bumper on the vehicle headlight; - It further comprises a vehicle shield, the presser means pressing the shield on the fender of the vehicle; the presser means comprise means capable of cooperating with means of the wing and of the headlight, in order to keep it on the headlight; - The cooperation means are able to cooperate with a retainer provided in the wing; - the presser means comprise means capable of cooperating with means of the bumper, in order to keep it on the wing; - The cooperation means are able to cooperate with a retainer arranged in the bumper; - The means forming the presser have come integrally on a support frame located in the vehicle; - The presser means are attached to a support frame located in the vehicle; - the presser means comprise means for fixing to a support frame located in the vehicle; - the presser means comprise curved means, the concavity of said means being turned towards the interior of the vehicle, the convexity of said means substantially matching the shape of the wall

  concave of the wing against which it is intended to come to bear.

  The invention also relates to the presser according to the invention.

DETAILED DESCRIPTION.

  Figure 1 shows the front part of a vehicle 1 comprising a wing 2 and a headlamp 3. The vehicle 1 also comprises a

bumper 4.

  It is specified that the description which follows presents the modes of

  possible embodiments of the invention for the "front" part of a vehicle.

  Of course, the invention also applies to the "rear" part of all

  vehicles, especially automobiles.

  Throughout the following description, words like "in front",

  "front", "rear", "back", "horizontal", "vertical", "upper", "top", "lower" and "bottom" for example are taken in relation to a

  normal direction of movement of the vehicle.

  Still with reference to FIG. 1, the part referenced by 20 represents the interface zone "wing 2 - projector 3" on which a

presser according to the invention will act.

  According to the invention, the presser means will press the wing 2

against the projector 3.

  FIG. 2 also represents a vehicle 1 comprising the same main elements as the vehicle in FIG. 1. The elements

  identical are referenced by similar references.

  In FIG. 2, the zone referenced by 30 represents an interface zone "wing 2 - headlight 3 - bumper 4" on which a mode of

  possible realization of the invention will exert its action.

  According to this embodiment, the presser means press

  the wing 2 against the headlight 3 and the bumper 4.

  FIG. 3 represents a first possible embodiment of a presser 5. According to this embodiment, the presser 5 is a separate part from a support frame 6 which is located inside the vehicle. The

  presser 5 is therefore fixed by means of fixing to the frame 6.

  According to a possible variant according to the invention not shown in the figures, the presser can be integral with the interior of the vehicle. Thus, there is no need to provide fixing means on the presser. The presser 5 has, seen from one side of the vehicle, generally a cross shape. The cross has a vertical element, the upper part of which flares from its upper end to a horizontal element. The lower part of the horizontal element is formed by a part of substantially constant thickness. The horizontal element is

  substantially of constant thickness also.

  FIG. 3 represents a front view of the embodiment of

the invention according to FIG. 4.

  According to this figure, the vertical element of the presser 5 comprises a substantially sickle-shaped element, the mean plane of which extends substantially perpendicular to one side of the vehicle. The sickle blade 53 is formed from a curved element. The concavity of the blade 53 is turned towards the interior of the vehicle. Thus' the convexity of the blade 53 substantially matches the shape of the concave wall

  of the wing 2 against which it is intended to come to bear.

  The blade 53 has at its upper end means 51 for fixing the presser. Of course, such fastening means are not

  necessary only when the presser 5 is a separate part from the frame 6.

  The fixing means 51 may comprise means complementary to means present on the frame 6. For example, the means 51 may comprise a hole complementary to a lug on the frame 6. The means 51 may also include an orifice allowing the fixing of the presser 5 on the frame by a screw-nut or rivet type system. It is also possible to provide a fixing by welding or gluing by

example.

  The blade 53 has on the front part of its cutting edge an anterior edge 58. The edge 58 comprises means able to cooperate with complementary means present on the inner wall of the wing 2 and / or of the

projector 3.

  The edge 58 comprises for example substantially in the middle, a

  protuberance coming from material on the edge 58 forming groove 55.

  The protrusion extends forward and towards the concavity of the blade 53. The groove 55 is able to cooperate with a retainer defined in the wing 2 of the vehicle. The protrusion has an edge 56 furthest forward relative to the direction of vehicle movement. The edge 56 is able to bear against

the projector 3.

  The handle 60 of the sickle consists of a substantially rectangular plate. The plate 60 extends substantially in the same plane as the mean plane of the blade 53. The plate 60 also includes fixing means 52. Of course, as before, such fixing means 52 are only necessary when the presser 5 is a separate part from the frame 6. The fixing means 52 may comprise means complementary to means present on the frame 6. For example, the means 52 may comprise a hole complementary to a stud on the frame 6. The means 51 may also include an orifice allowing the presser 5 to be fixed to the frame by a screw-nut or rivet type system. We can also plan

  fixing by welding or gluing for example.

  The horizontal element of the presser consists of a bar 54, substantially C-shaped. The concavity of the bar 54 is also turned towards the interior of the vehicle. The convexity of the bar 54 conforms appreciably to the pa king co n cavity of the pa king internal of wing 2 against the aq u el l e

  it is intended to support.

  The bar 54 includes means 57 able to cooperate with the wing 2,

  eVou the headlamp 3 eVou with the bumper 4 of the vehicle.

  The means 57 can also cooperate with a protective shield present on the lower part of the vehicle 1. Thus, the presser 5

  also presses wing 2 against said shield.

  In all cases, the cooperation means 57 may include orifices. These orifices are for example able to cooperate with retainers located on the bumper 4, the headlight 3, a shield eVou the wing 2. FIG. 5 represents a back view of the presser 5 according to FIG. 3. We find on this figure all the elements described with reference to Figure 4. Similar elements are referenced by identical numbers. Figure 6 is a top view of the embodiment of the invention of Figure 3. We see in this figure the curvature of the bar 54 which matches the concavity of the inner wall of the wing 2. We also see on

  This figure shows the orifices 57 formed in the bar 54.

  We also see in Figure 6 the widening of the blade 53 on either side of a mean plane 59 substantially perpendicular to the direction of

  moving the vehicle. Such flaring is carried out up to bar 54.

  It allows the blade 53 to more closely match the concavity of the inner wall of the wing 2. FIG. 7 is a perspective view of the mode of reinforcement according to FIG. 3. The numerical references are homogeneous with the references of the

previous figures.

  Fig 8 shows a schematic sectional view along the plane

Vl11-VIII of figure 1.

  According to this figure, the convexity of the blade 53 cooperates substantially

  with the concavity of the inner wall of the wing 2.

  Likewise, the means 55 forming the groove of the presser 5 cooperate with retaining means 61 formed in the wing 2. The means 55 also cooperate with the projector 3, since the edge 56 comes in

abutment against said projector 3.

  Thus, the wing 2 is kept pressed against the headlight 3.

  FIG. 9 shows the effects of the presser 5 on the wing 2 during a thermal expansion of the wing 2 for example. A similar reasoning could be carried out for an impact suffered by the vehicle which would have deformed

said wing 2.

  The dotted lines in Figure 9 show the position of wing 2

  in its normal position, namely when the play of aspect is minimal.

  The solid lines show the position of wing 2 after dilation

thermal or shock.

  The utility of the presser 5 is then understood: thanks to the means 55, the wing 2 is blocked in the reference direction by "X". In fact, the means 61 coming from the wing abut against the edges of the groove

  55. The means 61 include a retaining material coming from the wing 2.

  In addition, wing 2 is held in position in the "Y" direction since

  the wing 2 abuts with the wall of the headlight 3.

  The same reasoning applies when the means 57 cooperate with means coming from the bumper 4 eVou of the headlight 3 eVou of the vehicle shield. The various elements in cooperation with the presser 5 via the means 57 are pressed on the wing 2 and the play of appearance is reduced to a minimum during thermal expansion or

of a shock.

  The presser according to the invention therefore controls the clearances and outcrops between these parts, while preserving their functional requirements both in

regulation only in quality.

  It will be recalled that all of the above developments preferentially relate to a presser intended for the front part of a vehicle, but that the invention remains valid for a presser intended for the rear of a vehicle and that the main elements are found by symmetry through

  relative to a radial plane of the vehicle.
