- the equipment 3 is a rear seat of a motor vehicle, such as for example a car, and that the metal wall 5 is part of a lateral part rear 7 of the structure of this vehicle.
- the invention is not limited to this application. It relates in fact to any type of equipment comprising at least one metal axis which must be partially housed in an opening defined in a metal wall, whatever the system of which the latter is a part and whatever the system of which the equipment is a part. .
- it concerns at least vehicles (land, river (or sea), and air), installations, including of industrial type, and buildings.
- FIG. 1 An example of a part of a piece of equipment 3 comprising at least one metal axis 2.
- the equipment 3 is a rear seat of a vehicle, of the type bench seat and of which only part of the metal structure of the backrest can be seen.
- Such a structure comprises in its lower part two metal axes 2 right and left intended to be partially and respectively housed in two openings 6 defined in two metal walls 5 forming respectively part of the rear right and left side parts 7 of the structure of a vehicle automobile.
- FIG. 4 an example of a metal wall 5 forming part of a right rear part 7 of a vehicle structure and comprising an opening 6 intended to partially accommodate the right metal axis 2 of the structure 3 of figure 1.
- the metal axis 2 comprises a main part having a first diameter, intended to be housed partially in the opening 6, and terminated by a free end 8 having a second diameter strictly greater than the first diameter. Such an arrangement is intended to prevent the exit of the metal pin 2 from the opening 6.
- the invention notably proposes a method intended to prevent the generation of noise resulting from the friction of the metal axis 2 on a part 9 of the edge 4 which delimits the opening 6 defined in the metal wall 5 considered.
- the method according to the invention comprises two steps 100 and 1 10 which can be implemented by a technician (or more generally a person) having a ribbon 1 including a portion (defining a part 10 to which we will return more far) is illustrated without limitation in FIGS. 2 and 3.
- Such a tape 1 is made of a synthetic and flexible material.
- this tape 1 can be made of polyurethane or polypropylene or elastomer.
- elastomers which can be used, mention may in particular be made of ethylene-propylene-diene monomer (or EPDM), which is an amorphous terpolymer, and TPV (vulcanized olefinic thermoplastic elastomer).
- this ribbon 1 comprises a groove 1 1 having a width which is at least equal to the thickness of the edge 4 in order to accommodate a part 9 of the latter (4) which can be in contact with the metal axis 2, once the main part of the latter (2) is partially housed in the opening 6 (in the absence of part 10).
- the groove 1 1 can, for example, be delimited at least by first 12 and second 13 facing faces (in the absence of edge 4) and having respectively first h1 and second h2 different heights.
- the first height h1 is, for example, less than the second height h2.
- the ribbon 1 can, for example and as illustrated without limitation in FIGS. 2 and 3, include first 14 and second 15 parts which respectively comprise the first 12 and second 13 faces.
- the first part 14 has a third face 16 which is rounded and which leaves from one end of the first face 12.
- the second part 15 may have a fourth face 17 (external) which is substantially parallel to its second face 13.
- the thickness of the first part 14 of the ribbon 1 can be between 2 mm and 4 mm, and the thickness of the second part 15 of the ribbon 1 can be between 1, 5 mm and 3 mm.
- the width of the throat 1 1 of the ribbon 1 is a function of the thickness of the edge 4.
- the first h1 and second h2 heights are a function of the stresses undergone by the metal part 5. The greater these constraints, the greater the first h1 and second h2 heights.
- FIG. 6 An example of an algorithm allowing the method according to the invention to be implemented is illustrated in FIG. 6.
- the process begins when a technician (or a person) is located next to a metal wall 5, provided with an opening 6 delimited by an edge 4 and having to accommodate a metal axis 2 of equipment. 3, and that he (she) has a ribbon 1 with groove 1 1 of the type described above.
- a part 10 having a first length 11 which is at least equal to the second length I2 of a part 9 of the edge 4 which can be in contact with the metal axis 2 (in the absence of this part 10).
- each part 10 is advantageously defined to measure as a function of the opening 6 which it must equip, and more precisely as a function of the length I2 of the part 9 of the edge 4 which can be in contact with the 'metal axis 2 (once it has been housed in the opening 6).
- the second length I2 can be known in advance (for example by CAD / CAD), or else determined directly by the technician by placing a portion of the tape 1 against the opening 6.
- a second step 1 10 of the method we (the technician) place the part 10 which he has defined in the opening 6 by housing this part 9 of the edge 4 in its groove 1 1, before the introduction of the axis metallic 2 in this opening 6 so that it rests on this part 10. It will be noted that this introduction can be done just after the placement of the part 10 in the opening 6, or much later.
- the ribbon 1 can be initially wound.
- we (the technician) can unroll a part of the ribbon 1 in order to define the part 10 in this part unrolled by cutting.
- This cutting can be done using scissors or a cutting blade, for example.
- the technician can, in the second step 1 10, approach the part 10 of the wall metallic 5 by orienting it so that its first face 12 is closer to the latter (5) than its second face 13. This facilitates the introduction and placement of the part 10 in the opening 6, because c 'is the side of the groove 1 1 which has the first height h1 (the smallest) which is initially closest to the edge 4.
- the tape 1 also comprises first 14 and second 15 parts comprising respectively the first 12 and third 16 faces and the second face 13, we (the technician) can, in the second step 1 10 slide the third rounded face 16 against the part 9 of the edge 4 until the latter (9) is housed in the groove 1 1.
- This third rounded face 16 makes it even easier to introduce and place the part 10 in the opening 6.
- the invention offers several advantages, including:
