Description

Title of the invention: Anti-clip loss interior trim.

[0001] The technical field relates to passenger compartment trims designed to be stapled, assemblies comprising such trim and at least one staple, vehicle passenger compartments comprising at least one such assembly and finally motor vehicles having such a passenger compartment.

[0002] Automobile manufacturers are particularly focused on reducing the time and costs of manufacturing their vehicles in order to offer their customers vehicles at controlled prices. In this context, automobile manufacturers seek to optimize each stage of assembly, and in particular the interior trim stages. During some of these trim stages, trim panels are stapled to a passenger compartment structure using staples that are pre-positioned in pre-drilled holes in the panel. Thus, the trim panels are delivered to the assembly lines with pre-positioned staples.

[0003] The most commonly used staples are omega-type staples, which have a central portion from which fastening tabs extend. These staples are particularly effective at securing the panel to the structure. However, before being fastened to the structure, these staples have the disadvantage of easily detaching from the panel. Indeed, a staple positioned in a panel fastening hole can sometimes rotate within that hole, causing it to come out. The loss of pre-positioned staples obviously poses a problem during panel assembly on the production line.

[0004] Thus, there is a need for a solution to limit or avoid the loss of staples pre-positioned on a cladding panel.

[0005] The present invention aims to overcome the problems described above. In this technical context, one objective of the present invention is to provide a trim that limits or prevents the detachment of a clip pre-positioned on the trim before the trim is attached to a passenger compartment structure.

[0006] To this end, the present invention relates to a trim piece for a motor vehicle interior designed to be fixed to an interior structure by at least one clip, the trim piece extending between a first and a second opposing face, the trim piece having at least one clip hole, each designed to receive an omega-type clip, having a central portion from which fixing tabs protrude, the clip being inserted into the clip hole from the first face, each hole being delimited by a perimeter and extending along its own longitudinal axis, the first face having, around the hole and on each side of the longitudinal axis, at least one stop each projecting from the first face and positioned and sized to limit rotation around the longitudinal axis, forming a stop at the central part of an omega-type clip, with its fixing tabs engaged in the orifice, the limitation of rotation preventing the clip from coming out of the orifice.

[0007] The invention also relates to an assembly comprising a trim according to the invention and at least one omega-type staple pre-positioned in a stapling hole of the trim, such that its fixing tabs are engaged in the hole from the first face and such that its central part protrudes from the first face, the rotation of each staple around the longitudinal axis corresponding to the hole being limited by the corresponding stops of the hole.

[0008] The invention further relates to a motor vehicle passenger compartment comprising at least one assembly according to the invention, the trim being fixed to a passenger compartment structure by each clip of the assembly.

[0009] The invention finally relates to a motor vehicle having a passenger compartment according to the invention.

[0010] Thus, the trim according to the invention accommodates an omega-type staple in a stapling hole in the trim, allowing the staple to be pre-positioned before the trim is stapled. Thanks to the stops formed around each stapling hole, a pre-positioned staple is prevented from rotating sufficiently around its longitudinal axis to cause it to detach from the trim. Therefore, a staple pre-positioned in the hole, that is, with its fastening tabs engaged in the hole from the first face, is not at risk of coming out of the hole during handling of the trim before it is fastened.

[0011] According to one embodiment of the trim, at least one stop has a plane inclined with respect to a direction normal to the first face, facing the orifice and oriented so that the height of the stop increases away from the perimeter.

[0012] According to one possibility, the trim comprises, on each side of the longitudinal axis, two stops spaced apart from each other and each arranged so as to be positioned opposite a fixing tab of a clip engaged in the orifice.

[0013] According to one embodiment of the trim, each stop is shaped to limit the rotation to 45°, around the longitudinal axis, of a clip inserted into the orifice.

[0014] According to one possibility, each stop forms a rib extending in a direction perpendicular to the longitudinal axis.

[0015] Advantageously, each rib extends from the periphery of the orifice.

[0016] The invention will be better understood upon reading the following detailed description, given solely by way of non-limiting example and made with reference to the accompanying drawing in which:

[0017] [Fig.1] [Fig.1] represents a top view of an assembly according to the invention showing an omega-type staple introduced into a stapling hole.

[0018] A trim 1 according to the invention, illustrated in the figure, is designed to equip a motor vehicle passenger compartment, not shown, and to be fixed to a passenger compartment structure by at least one omega-type metal clip 2, illustrated in the figure. Such a clip 2 has a central portion 3 from which protruding fixing tabs 4 are designed to engage and fix the clip 2 to the structure.

[0019] The trim 1 extends between a first face 5 and a second opposite face, not shown in the figure. The second face is designed to face the structure to which the trim 1 is fixed.

[0020] The trim 1 has at least one stapling hole 6, each designed to receive a staple 2 inserted into the stapling hole 6 through the first face 5. Each fixing tab 4 is then engaged in the hole 6, the central part 3 of the staple 2 protruding from the first face 5. By way of example, the trim 1 is a door trim covering a vehicle door.

[0021] As illustrated in [Fig. 1], each orifice 6 is delimited by a perimeter 7 and extends along its own longitudinal axis AL, schematically shown in the figure. A clip 2 engaged in the orifice 6 then presents its central part 3 extending substantially along the longitudinal axis AL.

[0022] The first face 5 of the fitting 1 according to the invention has, around the orifice 6 and on each side of the longitudinal axis AL, at least one stop 8. Each stop 8 protrudes from the first face 5. Each stop 8 is positioned and dimensioned to limit rotation around the longitudinal axis AL, by forming a stop against the central part 3 of a clip 2, having its fixing tabs 4 engaged in the orifice 6. The limitation of rotation by each stop 8 prevents the clip 2 from coming out of the orifice 6.

[0023] In the example described in the figure, the trim 1 has, on each side of the longitudinal axis AL, two stops 8, spaced apart and each arranged so as to be positioned opposite a fixing tab 4 of a clip 2 engaged in the orifice 6.

[0024] Advantageously, at least one stop 8 has an inclined plane 9 with respect to a direction normal to the first face 5, facing the orifice 6 and oriented so that the height of the stop 8 increases away from the perimeter 7.

[0025] According to one possibility, at least one stop 8 is shaped to limit the rotation to 45° around the longitudinal axis of a clip 2 inserted into the orifice 6.

[0026] As illustrated in the figure, each stop 8 forms a rib 10 extending in a direction perpendicular to the longitudinal axis AL. Each rib 10 extends from the periphery 7 of the orifice 6.

[0027] An assembly 11 according to the invention is formed of a trim 1 according to the invention and at least one omega-type clip 2, pre-positioned in a stapling hole 6 of the trim 1, such that its fixing tabs 4 are engaged in the hole 6 from the first face 5 and such that its central part 3 protrudes from the first face 5. The rotation of each clip 2 around the longitudinal axis AL corresponding to the hole 6 is then limited by the corresponding stops 8 of the hole 6.

[0028] The assembly 11 according to the invention thus makes it possible to dress a passenger compartment according to the invention.

[0029] Thus, the trim 1 allows the staple 2 to be received in the stapling hole 6 to allow its pre-positioning before the trim 1 is stapled. Thanks to the stops 8 provided around each stapling hole 6, the pre-positioned staple 2 is prevented from undergoing sufficient rotation around the longitudinal axis AL to cause its separation from the trim 1. Thus, a staple 2 pre-positioned in the hole 6, that is to say with its fixing tabs 4 engaged in the hole 6 from the first face 5, is not at risk of coming out of the hole 6 during the handling of the trim 1 before its fixing.

[0030] The invention is not limited to the embodiment of the trim described above, only by way of example, but other embodiments can be devised by a person skilled in the art without departing from the scope and extent of the present invention.
