- Airbag duct for receiving a piece of trim
- the present invention relates to the field of vehicle interior trim parts adapted to cover airbag housings, and more particularly to the field of assembly of the airbag channel closure flaps with a piece of trim.
- an alternative is to perform a bonding which fixes the lining piece at a dedicated surface of the flap, its hinge and / or its peripheral frame .
- a glue requires perfect control of its removal and spreading on the structural surface, especially during the pressing step of the lining piece. Indeed, during this step, the glue may spread overflowing at the periphery of the flap and to secure the flap with the peripheral frame, slowing its opening.
- the present invention aims to overcome these disadvantages by providing an airbag channel adapted to allow the attachment of a piece of trim capable of masking the flap so that the attachment of this piece of trim can overcome its thickness. while avoiding any risk of parasitic locking related to this fixation.

- At least one interface for depositing an adhesive composition on at least one fixing portion at least one interface for depositing an adhesive composition on at least one fixing portion
- At least one sealing structure arranged to be positioned between at least one flap and a peripheral frame and at least one flap or hinge portion and to prevent spurious spreading of the adhesive composition out of the fastening portion.
- FIG. 1 illustrates a schematic example of an assembly according to the invention
- FIG. 2 illustrates certain details of a schematic example of a shutter of an assembly according to the invention
- FIG. 3 illustrates certain details of a schematic example of an arrangement for fastening a piece of trim on an example of part of an assembly according to the invention
- - Figures 4, 5 and 6 illustrate different schematized examples of spreading of the adhesive composition in an arrangement according to the invention
- FIG. 7 illustrates a schematic example of a production device participating in the pressing of an arrangement according to the invention
- FIG. 8 illustrates a detail of the schematized example of a production device according to FIG. 7 at the junction between two shutters.
- the invention relates to an assembly comprising an airbag channel 1, at least one hinge 9 for flap 2 associated with a peripheral frame 13 and arranged in a substantially plane arrangement made by one or more surfaces and intended to be covered by a piece of packing for assembly and fixing, characterized in that at least one of the elements of the assembly comprises at least one fastening portion 7 made by a surface portion intended to receive an adhesive composition 4 and intended to face a surface lower part of a lining piece 3, this fixing portion 7 being surrounded at the periphery by at least one projection 5.
- the spreading surface of this composition 4 is delimited by a projection 5 which provides a flange for barrier to prevent any overflow of the adhesive composition 4 to beyond the fixing portion 7 intended to participate in the attachment of the lining piece 3.
- This risk of overflow can occur in particular when covering the attachment surfaces 7 of the assembly by the lining piece 3.
- this lining piece 3 is pressed so that the adhesive composition 4 spreads substantially uniformly over the entire attachment surface 7.
- the projection 5 thus forms a barrier peripheral surrounding each spreading surface forming an attachment portion 7 for receiving an adhesive composition 4 and / or all of these spreading surfaces for fixing the lining piece 3.
- the fastening portion 7 is associated with at least one groove 6 disposed along at least a portion of the inner edge of the projection 5 which surrounds the fastening portion 7.
- This additional groove 6 thus provides a housing forming a space reservoir adapted to receive an excess of adhesive composition 4 when it is spread to the projection 5 at the periphery of the fixing portion 7.
- the groove 6 is preferably arranged along at least one projection portion 5 at which the overflow of an excess of adhesive composition 4 must imperatively be prevented to prevent formation of a parasitic junction between the element which carries the fixing portion 7 and a juxtaposed element.
- the construction of the shutter or flaps for closing the duct of the airbag channel 1 surrounded by the peripheral frame 13 may differ.
- At least a portion of the hinge 9 forming a substantially planar structure comprises at least one fastening portion 7.
- the flap is formed by a portion of the lining piece 3.
- At least a portion of the lining piece 3 is attached to a portion of a hinge 9 so that the flap is formed by a portion of the lining piece 3 delimited by a weakening of its structure.
- the lining piece 3 tears along the weakening to form a flap bound to its hinge 9 via a fixing portion 7.
- the flap 2 is an element of the assembly of the invention prior to the fixing of the lining piece 3.
- the lining piece 3 is then fixed to the flap 2 at the level of dedicated attachment portions 7.
- a fastening portion 7 is positioned at the flap 2
- this construction allows the fastening of the flap 2 directly to the lining piece 3 while avoiding unwanted attachment of the flap 2 with the edge of the opening of the duct. airbag 1 or the peripheral frame 13 closed by the flap 2, due to an undesired presence of adhesive composition 4 beyond the surface of the flap 2.
- the attachment of the flap 2 to the lining piece 3 also contributes to obtaining a sharper break of the lining piece 3 along the periphery of the flap 2.
- the projection 5 possibly associated with a groove 6 prevents overflow an excess of adhesive composition 4 at the portion of the lining piece 3 which masks the junction between the flap 2 and the edge of the opening of the airbag channel 1 or the peripheral frame 13.
- At least a portion of the projection 5 which surrounds the attachment portion 7 of the flap 2 is positioned along at least one edge of the flap 2.
- This positioning of a projection 5 along an edge of the shutter 2 makes it possible to obtain a spreading of the adhesive composition 4 optimized closer to the edge of the shutter 2 and thus to achieve a fastening of the shutter to the trim piece 3 which is optimal for obtaining a breaking of the lining piece 3.
- the breaking of the lining piece 3 is then specifically carried out along a line which runs along at least part of the edge of the flap 2.
- the groove 6 is positioned along a portion of the projection 5 located at the edge 2a of the flap 2 opposite the edge of the flap 2 which is associated with the hinge 9.
- a or more grooves 6 are positioned along projections 5 located at the edges 2a of the flap 2 which are intended to away from the peripheral frame 13 of the assembly of the invention which surrounds the flap 2, that is to say the edges 2a of the flap 2 which are not associated with the hinge 9.
- the groove 6 is arranged in a "U" arrangement so that the groove 6 runs along the projection 5 disposed along the edges 2a of the shutter 2 which are not associated with the hinge 9.
- the groove 6 is positioned along the inner edge of the assembly of the projection 5 which runs along the periphery of the shutter 2.
- the construction of the fastening portion 7 at a hinge 9 associated with a projection 5 and a groove 6 can be carried out in a similar manner to that directly relating to a flap 2.
- the assembly of the invention comprises at least one fixing portion 7 positioned at a peripheral frame 13 which surrounds an area intended to be closed by at least one flap 2. This area corresponds to all or part of the opening of the airbag channel 1 or the peripheral frame 13.
- This arrangement complementary to the fastening portion 7 of the lining piece 3 with the flap 2 makes it possible to obtain a fastening of the piece of lining 3 on the peripheral frame 13 to the flap 2 which also contributes to a clean break in the lining piece 3 when the flap 2 is opened.
- the construction of this fastening portion 7 thus also involves a protrusion 5 which can possibly be associated with a groove 6 to prevent the overflow of an excess of adhesive composition 4 during bonding of the lining piece 3 on the fastening portion 7 dedicated.
- Fixing the lining piece 3 with two juxtaposed surfaces formed by fixing portions 7 according to the invention thus makes it possible to optimize the efficiency and the sharpness of the break of the lining piece 3 in particular thanks to a piece of lining 3 of smaller thickness, while ensuring masking by the lining piece 3 of the junction of the flap 2.
- the invention also relates to an arrangement comprising a lining piece 3, characterized in that the arrangement also comprises: an assembly according to the invention,
- an adhesive composition 4 disposed between at least one attachment portion 7 of an element of the assembly and the lining piece 3.
- the adhesive composition 4 is arranged to cover at least one attachment portion 7 so that the front of the adhesive composition 4 is at least level with the junction of the groove 6 and the portion 7.
- This particular arrangement of the adhesive composition 4 is obtained, inter alia, during the spreading of the composition 4 which occurs in particular during the removal of the lining piece 3 and the pressing of the lining piece 3 against the fixing portion 7 intended to receive the lining piece 3.
- the invention also relates to a device for producing at least one arrangement according to the invention, by assembling at least one lining piece 3 with at least one element of the assembly, characterized in that the device comprises:
- At least one sealing structure 12 arranged to be positioned between at least one flap 2 and a peripheral frame 13 and at least one flap 2 or a hinge portion 9 and prevent spurious spreading of the adhesive composition 4 out of the portion

- the pressing device comprises in particular a complementary surface 11 of the inner face of at least a portion of the airbag channel 1 and the flap 2 or the hinge portion 9.
- This complementary surface 11 then comprises an arrangement that provides the sealing structure 12 adapted to be inserted, at least in part, in the space between the shutter 2 or the hinge portion 9 and the structure of the peripheral frame 13 and / or between the shutter 2 and a second shutter of the set emble or between portions of respective hinges 9 positioned vis-à-vis.
- the sealing structure 12 inserted in the dedicated space makes it possible to ensure a seal by preventing the overflow and infiltration of an excess of adhesive composition 4 in the gap formed by this space.
- This sealing structure 12 thus makes it possible to avoid the appearance of either a parasitic attachment between the shutter 2 or the hinge portion 9 and its element facing each other, or the appearance of a layer undesirable adhesive on the lining piece 3.
- This production device is arranged to be adapted to the space that exists between the shutter 2 or the hinge portion 9 and the peripheral frame 13.
- the sealing structure 12 is inserted into the entire space between the flap 2 or the hinge end portion 9 and the frame device 13.
- the sealing structure 12 is made by a plurality portions intended to be inserted into the different spaces that separate these junction points between the flap 2 and the peripheral frame 13.
- the production device is characterized in that, the assembly of the invention comprising at least two flaps 2 or two portions of ends of hinges 9 joined at a junction, the structure of 12 is arranged to be positioned between the two flaps 2 or the two end portions of hinges 9.
- the lining piece 3 may include a localized reduction in its thickness which corresponds to a weakening of the resistance of the lining piece 3 to facilitate its breaking and create a preferential and controlled breaking / opening line. This weakening of the lining piece 3 is then arranged along the space separating the two flaps 2 or end portions of hinges 9.
- the production device is characterized in that that the sealing structure 12 is formed by at least one rail of complementary shape to at least a portion of the space separating one end of a hinge 9 or a flap 2 of the peripheral frame 13 or a second hinge 9 or 2, the sealing structure 12 also comprising a blade 14 surmounting the rail and intended to be inserted into a weakening 8 of the trim piece 3.
- the sealing structure 12 is thus adapted to close the portion of the lining piece 3 whose thickness is reduced. This closure serves to protect the weakening of the lining piece 3 from a parasitic presence of adhesive composition in order to maintain a facilitated break in the lining piece 3.
- the blade 14 has a dimensioning complementary to the blind hole which forms the weakening 8 of the lining piece 3.
- the dimensioning of the blade 14 is intended to be positioned in the weakening 8 of the trim piece 3 without marrying perfectly the shape.
