Description

Template for placing a piece of adhesive covering on a rabbet of a body part of a motor vehicle.

The present invention relates to the field of trim parts reported on a body part of a motor vehicle, to identify, decorate or display regulatory information for example. The invention more specifically relates to positioning templates of the trim piece on the bodywork element.

A motor vehicle comprises a body composed of various body elements assembled together to form a superstructure covered with a covering. It is common that one or more bodywork elements are provided with a dressing part arranged in adhesive wafer. Such a dressing part comprises in particular at least one inscription, such as for example an identification mark, a decoration or regulatory information.

There is the problem of positioning and fixing the dressing part in a location provided on the bodywork element. Such an operation is commonly carried out by an assembler on a vehicle assembly line, after assembly of the body elements that the body comprises.

According to a known technique, the covering part is fixed to the bodywork element by gluing, in particular via a film or adhesive film having a high adhesion coefficient placed on at least one face of the intended dressing part. be oriented towards the bodywork element. The adhesive side of the trim piece is coated with a protective film pending its installation on the bodywork element. For the positioning of the trim piece on the bodywork element, the fitter uses a template on which he installs the trim piece prior to its attachment to the bodywork element.

The template has a specific form complementary to the shape of the bodywork element in its area dedicated to receiving the dressing part. An indexing means allows the fitter to position the template on the bodywork element in a predefined position of installation of the dressing part. Such an indexing means is for example formed by a set of cooperating visual marks which are respectively formed on the bodywork element and on the template.

The dressing part is installed on the template via a socket or adhesive film with a low coefficient of adhesion. The fitter removes the protective film covering the adhesive side of the trim piece, then installs the carrier template of the trim piece on the bodywork element, taking into account the indexing means for its positioning. Then the editor presses the dressing part against the bodywork element for its bonding via its adhesive side, and removes the template of the dressing room.

For a technological environment close to the present invention, one can for example refer to the document FR 2 931 781 (PEUGEOT CITROEN AUTOMOBILES SA) or the document EP 1 314 612 (BURG DESIGN GmbH), which disclose installation methods , via a template, a dressing part on a bodywork element of a motor vehicle body.

In this context, the use of a template for the positioning of a trim part on a bodywork element has several constraints, disadvantages and / or difficulties to overcome.

The bodywork elements that comprise the body are normally painted prior to the installation of the dressing part. As a result, the template must be installed on the bodywork element with care, to avoid impacting the bodywork element and / or degrade the paint it is coated.

In addition, the templates are designed and made to match the conformation of the bodywork element. However, the bodywork element is likely to have a complex shape in the installation area of the dressing room. This is for example the case when the template is installed on a more or less complex three-dimensional rebate.

For example, a trim piece is commonly placed on the threshold of an access opening inside the vehicle for a passenger. Such a door threshold frequently has a three-dimensional rabbet of complex shape, which complicates the design, implementation and implementation of the template on the rabbet. It comes out a significant cost to allow the installation of the dressing room at the base of the rabbet. In addition, a jig of complex shape is often derived from a rigid material to provide its conformation. This has the consequence of involving a non-negligible cost of the template.

There are templates of cellular material that have the advantage of being less expensive. However, such templates are not suitable for installation on a complex shaped surface. Their use is rather reserved for an apposition of the template on a flat surface or simple form. The natural conformal holding of a template from a blank made of cellular material, is not appropriate to retain its shape after being printed in its plane by a fitter by applying the template against the complex shaped surface.

Indeed a template from a blank made of cellular material is provided to fit the shape surface of the bodywork element, possibly being shaped in its general plane by the fitter from its application against the surface of form . However, in the case of a surface of complex shape, the natural holding of the thus shaped blank is insufficient to then maintain the form printed on the template by the editor. In addition, the time required for the editor to format the template is economically unsatisfactory with respect to the mounting costs induced.

In this context, the invention relates to a template configured for the installation of a trim part at the base of a rabbet that comprises a bodywork element of a motor vehicle body. The invention also relates to a set of members comprising a said dressing part equipped with a template of the invention for its installation on said bodywork element.

An object of the invention is to provide such a template capable of providing a correct positioning of the trim piece on the bodywork element, including in the case where said rabbet has a complex three-dimensional shape.

Another object of the invention is to propose such a template, the arrangement of which makes it possible to limit the costs incurred by the installation of the covering part on the bodywork element, in the context of a notoriously severe economic competition. in the automotive field. It is more specifically the object of the invention to reduce the cost of obtaining the template and / or the costs involved in its implementation, in particular by facilitating the installation of the template by a fitter on the bodywork element.

Another object of the invention is to provide such a template to limit the risk of clashes or injuries that may deteriorate the bodywork element during the installation of the dressing room.

The template of the invention is configured for the installation of a trim piece at the base of a rabbet that comprises a bodywork element of a motor vehicle body. For this purpose, the template comprises at least a first wall which is mainly extended along a horizontal plane of longitudinal-transverse extension. The first wall is dedicated to the reception of the dressing part via a reversible junction means, so that the dressing part is arranged at a location dedicated to the base of the rabbet.

The template also has at least a second, mainly vertical extension wall. The second wall is particularly dedicated to the positioning and / or maintenance of the template on the rabbet at a predefined location. For this purpose, said at least one second wall is provided with at least one holding member of the jig adapted to cooperate with a flange of the rabbet to maintain the jig in position on the bodywork element.

According to the invention, the template is mainly recognizable in that a said second wall is formed at at least one of the longitudinal ends of the first wall, being oriented in a vertical-transverse plane.

In other words, said at least one second wall extends in a substantially vertical plane which is oriented in the transverse direction of extension of the first wall.

If necessary to appreciate the relative concepts used to describe the invention: -) the template is considered geometrically with respect to an orthonormal reference conventionally defined by a longitudinal direction, a transverse direction and a vertical direction. As a result, the longitudinal, transverse and vertical notions are relative notions in the orthonormal frame typically defining the relative extensions of the template and / or its components along the directions defining the orthonormal frame. -) consequently the notions base and vertex or other related notions, are relative notions considered in the vertical direction. The relativity of the base or top concepts of the template are considered in relation to the first wall which is arranged at the base of the template. It takes into consideration the position of the template with respect to the rabbet of the bodywork element, which is defined with respect to said orthonormal frame whose directions correspond to the directions conventionally defining the extension of a vehicle and / or its components. .

The template thus has an L-shaped longitudinal-vertical profile in the case where only one second wall is provided at any of the longitudinal ends of the first wall. In the preferred case where the template has two second walls respectively formed at the longitudinal ends of the template, the template thus has a U-shaped longitudinal or vertical profile or in other words shaped stirrup.

Thus, the template is adapted to be installed via said at least one second wall on a longitudinal-vertical extension wing that has the rabbet at its top. The second wall is then able to be oriented generally perpendicularly to the longitudinal-vertical extension plane of the flange of the rabbet, being held in position on the flange via a said holding member provided on the second wall.

Such a configuration of the template has several advantages: -) The template can be formed from a semi-rigid material, including a cellular material, while having a satisfactory conformation holding when installed on the rabbet. Such holding of the jig results in particular from the combination between the extension of the first wall along the longitudinal-vertical plane and the extension to at least one of its ends of said at least one second wall along the vertical-transverse plane. . Said at least one second wall may be formed by a flap formed by folding a semi-rigid blank at at least one of its ends. -) The holding member may be formed of at least one socket formed through the or the second walls. Such a socket may advantageously be formed of a slot emerging on the outside of the template and which extends in a vertical-transverse plane or in other words which extends along the edge of the second wall and / or which extends along the thickness of the second wall. Such a slot can be advantageously formed by cutting the blank through the second wall.

The semi-rigid material from which the template is derived is potentially a plastic material, the blank then being formed in particular of a flexible plate of small thickness of plastic material. Such a solution is not preferred because expensive than the exploitation of a cellular material.

Thus according to an advantageous embodiment, the template is formed from a blank of semi-rigid material comprising at least one of its longitudinal ends a shutter forming a said second wall.

Preferably, the material of the blank from which the template is formed is a cellular material, cardboard in particular.

The cardboard may be formed in particular by laminating paper sheets giving the walls of the template a rigidity in their general plan which is adapted to the function of the template while limiting at best its cost of obtaining and / or its thickness. It can also be avoided the exploitation of cellular cellular material, deemed more rigid but more expensive.

The formation of the template from a semi-rigid blank, especially of cellular material, has several advantages: -) The template can be obtained at lower costs by cutting and folding the blank, while having its conformation sufficient rigidity . -) The second or walls can be formed by one or two hinged flaps via an embrittlement line on the blank. In other words, the second wall or walls are formed at lower cost by being arranged as an articulated flap with respect to the first wall, via at least one transverse weakening line formed on the blank. -) The template holding member on the rabbet may be formed of at least one said socket provided at lower cost by cutting the blank during its formation. -) The cutout being formed in the thickness of the blank, and therefore in the thickness of the second wall, the maintenance provided template on the rabbet is satisfactory. -) The slices of the cut may if necessary deform during the installation of the template on the rabbet, by narrow introduction of the wing inside the cut. The slices of the cut-out can then be compacted on themselves, conferring on the holding member an elastic clamp configuration of the flange of the rabbet on which the template is installed. -) The cutout can be configured narrow wedge fitting template on the flange of the rabbet, which reinforces the maintenance position of the template on the rabbet. -) The slices of the blank can be shaped when cutting the blank so as to marry more or less closely three-dimensional shape variations of the rabbet. The slices of the cutout can also spontaneously deform during the installation of the template on the rabbet, so as to follow more or less tightly three-dimensional shape variations of the rabbet. Such spontaneous adaptations of the means for holding the template on the rabbet may, in isolation or in combination, reinforce the support of the template against the rabbet via the slices of the cut, and thus the holding in position of the template on the rabbet. -) The template can be packaged flat along the horizontal plane of the blank. The storage and / or transport costs of a plurality of stacked templates are reduced. The shaping of the template can be quickly carried out at lower cost by the editor, by flap flaps along the vertical-transverse plane of extension of the second wall. -) The material of the template is unfit to injure the bodywork element.

To reinforce the holding of the template on the rabbet, the template preferably comprises a pair of second walls respectively formed at the longitudinal ends of the first wall.

In other words according to one embodiment, the template comprises a pair of second walls respectively formed at the longitudinal ends of the first wall.

More specifically, the blank preferably comprises at each of its longitudinal ends a constituent flap of a said second wall.

According to one embodiment, said at least one second wall has a first portion extending along the edge of the first wall. Said first portion is extended by a second portion which is provided with said holding member and which extends outwardly of the first wall along the vertical-transverse extension plane of the second wall. The holding member is more specifically formed of at least one cutout formed through said at least one second wall and configured as a hooking member. Such a hooking member is adapted to maintain by hooking the template on an outer member, in particular a flange of the rabbet on which the template is adapted to be suspended via the hooking member formed by the cut. Such suspension of the template on the rabbet is limited in particular by the vertical abutment of the template against the base of the rabbet provided to receive the dressing part.

According to one embodiment, the cutout has an outward opening out of the template which has a flare open towards the outside of the template. The flare is defined in particular between the edges of the outlet generally oriented transversely to a general rectilinear extension of the cut.

Thus according to one embodiment, the cut is mainly extended in a rectilinear general extent, preferably being at least partly tapered towards its bottom. The taper of the cut-out towards its bottom confers on it, in particular, a female wedge configuration of close fitting of the template on the rabbet.

Preferably, said at least one second wall forms a visual indexing index of a longitudinal positioning of the template.

The visual cue formed by the second wall is in particular intended to cooperate with a visual cue formed on the rabbet, in particular by aligning the second wall with the visual cue that includes the rabbet. The invention also relates to a set of members comprising a template according to the invention and a said dressing part. The template and the dressing part are in particular assembled to one another via said reversible junction means.

The reversible junction means between the template and the dressing part is preferably formed of an adhesive material, in particular with a low coefficient of adhesion, such as a repositionable adhesive for example. According to a variant, said reversible junction means may be formed of at least one socket that includes the trim piece for receiving the blank constituting the template.

The dressing part is in particular arranged in a wafer provided with an adhesive material, in particular with a high coefficient of adhesion, for its attachment to the rabbet. The adhesive material is provided on a lower face of the covering part which is opposed to an upper face of the covering part via which the covering part is joined to a lower face of the first wall of the template by the means reversible junction.

Such an assembly of members can be assembled in the workshop and then delivered to the assembly station of the trim piece on the rabbet. It will be noted that the formation of the template from a semi-rigid blank, in particular made of cellular material, makes it possible to minimize the storage and flat transport of said set of members along the horizontal plane of extension of the first wall of the template and / or dressing room.

More particularly according to a particular method of implementing a set of organs of the invention: -) An operator assembles the dressing part and the template via the reversible jointing means. The template, preferably from a blank, may be spread along the horizontal plane of extension of the blank or in other words according to the horizontal plane of extension of the first wall or in other words still according to the horizontal plane of the blank. extension of the dressing room. -) The assembly of organs thus obtained is then conveyed to a mounting station dedicated to the installation of the trim part on said bodywork element. -) An editor then folds said at least one flap perpendicular to the first wall according to its transverse extension. -) The installer then installs the template on the flange of the rabbet via the holding member, using the flap as a visual index of a longitudinal positioning of the template on the rabbet, in particular with respect to a visual reference that includes the rabbet. -) Then the fitter sets the dressing part at the base of the rabbet via the adhesive and removes the template by applying a force causing the reversion of its junction with the dressing room.

An exemplary embodiment of the present invention will be described as an indication and not restrictive with regard to other possible embodiments of the invention, in relation to the figures of the attached plates, in which: -) Figure 1 is a Partial illustration in perspective of a body part of a motor vehicle, on which is reported a piece of clothing. - Figure 2 is a partial perspective illustration of the bodywork element shown in Figure 1, which is installed on a carrier template of the trim piece in the fastening position on the body member. FIG. 3 is an exploded perspective illustration seen from below of the template and the dressing part shown in FIG. 2. FIG. 4 is an illustration in perspective seen from above of the template and the part of FIG. cladding shown in Figures 2 and 3, in the assembly position to one another. FIG. 5 is a flat illustration of a blank made of cellular material, from which the template shown in FIGS. 2 to 4 is formed.

The figures and their description expose the invention in detail and in particular ways of its implementation. They can of course be used to better define the invention, both in its particularities and in its generality, particularly in relation to the general description of the invention that has just been made.

In FIG. 1, a bodywork element 1 of a motor vehicle body is provided with a covering part 2. According to the illustrated example, the bodywork element 1 has a threshold of an access opening. inside the vehicle by a passenger. The trim part 2 has an inscription 3 relative for example to the mark of the vehicle.

In FIGS. 1 to 4, the covering part 2 is arranged in a plate extending in a horizontal-transverse plane L1-T1 which is defined by a longitudinal direction L1 and a transverse direction T1 of an orthonormal reference L1-T1. -V1. Such an orthonormal identifier classically identifies the extension directions of the body and / or its components.

In Figures 1 and 2, the body member 1 comprises a rabbet 4 which has a three-dimensional shape more or less complex in the directions of the orthonormal landmark. The rabbet 4 has a wing 5 which is formed at its top in a vertical direction V1 of the orthonormal frame. The wing 5 is formed at the edge of the rabbet 4 which is oriented towards the outside of the body, and extends in a longitudinal-vertical plane L1-V1 defined by the vertical direction V1 and the longitudinal direction L1.

In FIG. 2, the wing 5 of the rabbet 4 is used to fix the trim piece 2 to the base 6 of the rabbet 4 via a jig 7.

In FIGS. 3 and 4, the jig 7 comprises a first wall 8 intended to temporarily carry the cladding part 2, pending its attachment to the bodywork element 1. The first wall 8 extends according to the horizontal-transverse plane L1-T1 of extension of the covering part 2. The covering part 2 is intended to be temporarily assembled to the template 7 via the first wall 8.

More particularly, the lower face of the first wall 8 receives the covering part 2 according to their horizontal-transverse planes L1-T1 extension. The cladding part 2 and the first wall 8 are assembled to one another via a reversible junction means 9 which is formed on the lower face of the first wall 8 of the template 7. In the illustrated example, the junction means 9 is formed of a first adhesive material 10 which at least partly covers the underside of the first wall 8, in the form of a film or a film for example.

The covering part 2 is provided on its underside with a fastening means 11 for holding it at the base 6 of the rabbet 4 of the bodywork element 1. In the illustrated example, the fastening means 11 is formed of a second adhesive material 11a with a higher coefficient of adhesion than the first adhesive material 10. In other words, the fastening means 11 provides a junction between the trim piece 2 and the body part 1 which is more robust than the reversible assembly between the jig 7 and the covering part 2 provided by the junction means 9.

Thus, when the template 7 carrying the covering part 2, via the first adhesive material 10, is installed in position on the rabbet 4 as illustrated in FIG. 2, a pressure exerted by an assembler against the first wall 8 of the jig 7 causes the fixing piece 2 to be fixed to the base 6 of the rabbet 4 via the second adhesive material 11a. The jig 7 can then be easily removed by the fitter with the effect of breaking the junction between the jig 7 and the covering part 2 provided by the first adhesive material 10.

The jig 7 comprises second walls 12a, 12b for its installation in the required position on the flange 5 of the rabbet 4. The second walls 12a, 12b are formed at the longitudinal ends L1 of the first wall 8, being oriented in a plane vertical-transverse V1-T1. The second walls 12a, 12b are thus oriented perpendicularly to the longitudinal-transverse plane L1-T1 of extension of the first wall 8, bordering the transverse edges T1 of the longitudinal ends L1 of the first wall 8.

The second walls 12a, 12b each comprise a holding member 13 of the template 7 on the flange 5 of the rabbet 4, in particular by hooking. The holding members 13 are each configured in a socket 13a. When the template 7 is installed on the bodywork element 1 as illustrated in Figure 2, the wing 5 of the rabbet 4 is inserted inside the sockets 13a. The vertical extension V1 of the second walls 12a, 12b and the vertical extension V1 of the sockets 13a forming the holding members 13, are relatively defined to certify the application of the trim piece 2 against the base 6 of the rabbet 4 prior to contact between the top of the wing 5 and the bottom of the sockets 13a or in other words holding members 13.

In Figure 3, the template 7 is formed of a blank 14 of cellular material shaped by cutting and bending. The blank 14 comprises a main part 15 leaving the first wall 8 of the template 7. The main part 15 of the blank 14 is transversely T1 bordered at its longitudinal ends by flaps 16a, 16b constituting the second walls 12a, 12b of the template 7.

The blank 14 comprises weakening lines 17a, 17b separating the main portion 15 from the blank 14 of the flaps 16a, 16b, to allow flap flaps 16a, 16b perpendicularly to the horizontal-transverse plane L1-T1 extending the blank 14.

The flaps 16a, 16b can thus be folded by an assembler to arrange them perpendicularly to the first wall 8 of the jig 7 and thus to orient the second walls 12a, 12b formed by the flaps 16a, 16b perpendicular to the first wall 8. The flap of the flaps 16a, 16b is made by the assembler prior to the installation of the template 7 carrying the trim piece 2 on the rabbet 4 of the bodywork element 1.

The flaps 16a, 16b constituting the second walls 12a, 12b of the jig 7 each comprise a first portion 18 which extends along the edge of the first wall 8 along the weakening lines 17a, 17b. The first portion 18 of the flaps 16a, 16b is extended by a second portion 19 which extends along the horizontal-transverse plane L1-T1 of extension of the blank 14 considered flat.

The second portion 19 of the flaps 16a, 16b extends in the transverse direction T1 in overflow of the first portion 18 of the flaps 16a, 16b. In other words, the second part 19 of the flaps 16a, 16b, and therefore the second walls 12a, 12b of the jig 7, extends transversely overflow T1 of the first wall 8 of the jig 7. The second parts 19 of the flaps 16a, 16b , and therefore the second walls 12a, 12b of the template 7, comprise, through them, the sockets 13a constituting the holding members 13 that includes the template 7 for its installation on the wing 5 of the rabbet 4.

More particularly, the blank 14 has cutouts 20 formed through the second parts 19 of the flaps 16a, 16b, to form the holding member 13 of the template 7 on the rabbet 4 of the bodywork element 1. The blanks 20 present each an outlet 21 which has a flaring 22 open towards the outside of the blank 14 and thus of the template 7. The flaring 22 of the outlet 21 of a cut 20 considered is extended towards the inside of the blank 14 by a rectilinear extension 23 cutouts 20, which is preferably at least partly tapered towards the bottom of the cuts 20.

When the jig 7 is installed on the bodywork element 1 as illustrated in FIG. 2, at least one of the second walls 12a, 12b of the jig 7 forms a visual indexing index of a predefined positioning of the jig 7 on the rebate 4. The index or indices formed by the second walls 12a, 12b cooperates visually with at least one visual mark 24 formed on the rebate 4, to allow the installer to install the template 7 in the required position on the rabbet 4 .

According to the example illustrated in Figures 1 and 2, the visual cue 24 equipping the rabbet 4 may be formed of a marking formed on the rabbet 4, such as a stamped. Such stamped household for example a moisture evacuation channel may be retained by the rabbet 4 dressing the threshold of the access opening to the vehicle interior.
