DETAILED DESCRIPTION

[0027] With reference to the figures, a description is given of a folding interior lining panel 1 for a motor vehicle, the panel having the following features: [0028] it comprises first 2 and second 3 flaps articulated on each other on two respective articulation edges 4, so as to allow rotation of substantially 360 of one of the flaps with respect to the other, so that the panel can have a use configuration where the flaps are in line with one another in a substantially coplanar fashion, and two retracted configurations corresponding to a folding through 180 in one direction or the other, [0029] the sides 21 of the flaps at the edges have a similar thickness 26, [0030] the flaps have respectively a first 6a and second 6b front face and a first 7a and second 7b back face, the front faces being respectively covered with a first 25a and second 25b front covering layer, for example made of carpet or nonwoven material,
the articulation between the flaps being formed by: [0031] at least two first strips 8 spaced apart from each other, the strips being integral with the first layer, the strips having a free end portion 27a attached to the second back face so as to leave clear a middle portion 9a, the dimension of which in a direction perpendicular to the edges corresponds substantially to the thickness, [0032] and at least one second strip 12 arranged between the first strips, the strip being integral with the second layer, the strip having a free end portion 27b attached to the first back face so as to leave clear a middle portion 9b, the dimension of which in a direction perpendicular to the edges corresponds substantially to the thickness.

[0033] The flaps may be based on various materials, for example based on polyurethane, injected plastics material, with a honeycomb structure, extruded and blow-moulded plastics material, etc.

[0034] According to the embodiment depicted in FIG. 1, two first strips 8 are disposed substantially at the lateral ends of the edges 4.

[0035] According to one embodiment, the end portions 27a, 27b of the strips 8, 12 are attached by adhesive bonding.

[0036] Naturally, any other attaching method may be providedsuch as stapling, screwing, etcknowing that it is possible to combine a plurality of methods with each other.

[0037] According to the embodiments depicted, the first 2 and second 3 flaps are respectively covered on their back faces 7a, 7b with a first 28a and second 28b back covering layer, for example based on a sheet of plastics material, nonwoven material, or textile coated with plastics material, the end portions 27a, 27b of the strips 8, 12 being inserted between the back face 7b, 7a and the back covering layer 28b, 28a of the corresponding flap 3, 2.

[0038] According to the embodiments depicted, the flaps 2, 3 are provided with housings 20a, 20b for receiving the end portions 27b, 27a of the strips 12, 8, so that the end portions do not form a projection with respect to the back faces 7a, 7b of the corresponding flaps 2, 3.

[0039] According to an embodiment that is not shown, at least one strip 8, 12 is reinforced on its back with a reinforcing layer in order to improve the tensile strength thereof.

[0040] According to one embodiment, the reinforcing layer extends along the strip 8, 12 while encroaching in particular on the front face 6a, 6b of the flap 2, 3 with which the strip is integral, so as to provide reinforcement all along the strip.

[0041] The reinforcing layer is associated for example by adhesive bonding to the strip 8, 12.

[0042] The reinforcing layer is for example based on fabric used for manufacturing airbags, so as to have high tensile strength.

[0043] According to the second embodiment depicted, the flaps 2, 3 are produced by extrusion-blow moulding, the back of the strips 8, 12 being secured to a respective sheet 29 of plastics material integral with the flaps, the sheet being connected to the flap 2, 3 with which it is integral by means of a first zone of thinned material 30a so as to form a flexible hinge, the sheet having a second zone of thinned material 30b situated at the interface between the middle portion 9a, 9b and the end portion 27a, 27b of the strips.

[0044] In this case, provision can be made for fixing the free ends 27a, 27b of the strips 8, 12 in the same way as in the first embodiment, knowing that it is also possible to envisage attachment by welding.

[0045] In variants, not shown, applicable to all embodiments, it is possible to provide more than two first strips 8 and also more than a single second strip 12, as it is the case in the embodiment in FIG. 1, which provides two second strips 12.

[0046] In all embodiments, the strips 8, 12 may at leisure be staggered in alternation and/or in series.

[0047] In all the embodiments, in a way that is not shown, it is possible to provide for the front covering layers 25a, 25b of the flaps 2, 3 to cover, outside the zones of the strips 8, 12, the edges 21 of the flaps, and also folded over on a peripheral zone of the back faces 7a, 7b of the flaps, so as to provide an optimum peripheral finish.
