Definitions
- the invention relates to an interior panel intended to be mounted on a base box of a structural element of a body of a motor vehicle, said panel being composed of at least one lining of thermoplastic material of the expanded polypropylene type or PPE (in English EPP, Anglo-Saxon acronym for Expanded PolyPropylene) and a covering skin, composed of at least two adjacent covering portions assembled on the lining, each covering portion comprising, at the level of a region junction between the two coating portions, a curved edge inwardly of the panel cooperating with each other.
- PPE in English EPP, Anglo-Saxon acronym for Expanded PolyPropylene
- the invention applies in particular, but not exclusively, to motor vehicle side door panels.
- EPP is a particularly suitable material. It is in fact a very light plastic material which allows any suitable shape to be obtained.
- EPP is commonly used in the automotive industry, particularly for the production of door panel linings.
- FIG. 1 schematically illustrates a perspective sectional view of an interior panel 10 of a side door of a motor vehicle, comprising a base box 11 on which is fixed the inner panel 10, the inner panel 10 is composed of a lining 12 of thermoplastic material of the expanded polypropylene type, or PPE, comprising fastening means 13 to the base box 11, and of a covering skin 14, This is composed of two adjacent covering portions 14a, 14b, for example a first upper portion 14a and a second lower portion 14b, these two portions possibly having a variable appearance.
- the two adjacent covering portions 14a and 14b of the covering skin 14 are assembled on a covering surface 120 of the PPE lining 12, for example by gluing, to form the covering skin of the panel.
- the upper 14a and lower 14b coating portions of the skin 14 each have a curved edge 140a, 140b cooperating with one another. More particularly, the curved edges 140a, 140b are arranged substantially perpendicular to the remains of the portions 14a and 14b and are assembled one against the other and arranged so as to project into the thickness of the lining 12, in a trench 20 provided for this purpose, that is to say towards the inside of the panel 10, so as to hide this connection.
- the lining 12 comprises a rigid insert 15, of injected plastic, inserted into the thickness of the lining 12, to provide rigidity at this level. region. More specifically, this insert 15 is shaped so as to form a double U-section, the internal wings 16 of which, facing one of the other, which extend in the thickness of the lining 12, are connected by their respective free ends, so as to form, in the space reserved between them, the trench where the curved edges 140a, 140b of the adjacent covering portions 14a, 14b assembled on the lining 12.
- the respective cores 17 of the two U-shaped sections of the insert 15 then extend opposite one another flush with the surface of the lining 12 over a certain distance, on either side of the trench formed in the thickness of the lining 12, and the respective outer flanges 18 of the two U-shaped sections extend in the thickness of the lining 12 in a plane substantially parallel to that of the inner wings 16.
- the transition zone 19 on the surface between the rigid plastic of the insert 15 and the expanded plastic of the lining 12, defined at the border (on the side opposite the trench 20) of the respective cores 17 of the double section in U extending flush with the surface of the lining 12, generates appearance defects on the surface of the skin.
- an object of the invention is to remedy this drawback, by proposing an interior panel, such as an interior panel of a motor vehicle side door, for which the visual perception of the panel is improved, in particular at the level of the regions junction between the adjacent coating portions constituting the covering skin of the panel.
- the invention relates to an interior panel, intended to be mounted on a base box of a structural element of a body of a motor vehicle, said panel being composed of at least one lining of thermoplastic material of the expanded polypropylene type, having a covering surface, and a covering skin, composed of at least two adjacent covering portions assembled on said covering surface of said lining, each covering portion comprising, at the level of a junction region between said two adjacent covering portions, an edge curved towards the inside of the panel, the respective curved edges of the two adjacent covering portions being assembled one against the other and arranged so as to protrude into a trench provided for this purpose in the thickness of said lining, said lining comprising a rigid insert embedded in its thickness at the level of said junction region, said panel being characterized in that said insert has an inverted pi shape in axial section with a base embedded in the thickness of said lining opposite said lining surface with respect to said trench and a pair of wings parallel to each other extending from said base to said surface coating, so as to form the side walls of said
- the transition zone between the expanded plastic of the liner and the rigid plastic of the insert embedded in the liner at the junction region is limited exclusively to the zone of the coating surface of the liner where comes flush with the free end of the wings of the pair of wings of the pi-shaped insert.
- these wings define the side walls of the trench in which the respective curved edges of the two adjacent coating portions project, so that their free end is arranged immediately opposite the curvature of these respective curved edges when the two portions adjacent liners are joined to the liner's liner surface.
- the rigid plastic/expanded plastic transition zone which is thus offset directly at the beginning of the curvature of the respective curved edges of the two adjacent covering portions, is therefore advantageously included in a zone of change of shape of the panel and therefore, will no longer be visualized as a defect in the appearance of the skin surface.
- said pair of wings has free ends arranged flush with the surface of said lining, said free ends defining free edges of said trench at right angles to which are formed connecting roundings with a convex section in the form of an arc of circle, connecting said edges respective curves of said coating portions adjacent to the rest of said portions.
- said base extends continuously and substantially parallel to said coating surface, over a certain non-zero distance on either side of the bottom of said trench.
- said distance is at least equal to the depth of the trench.
- said lining comprises removable fastening means to said base box.
- said panel according to the invention is a motor vehicle side door panel.
- the invention also relates to a motor vehicle comprising a panel as described above.
- FIG. 1 schematically illustrates a perspective sectional view of an interior panel of a side door of a motor vehicle, according to the prior art and has already been described;
- FIG. 2 shows the panel shown schematically in Figure 1, adapted in accordance with the present invention.
- Figure 2 shows the same elements as Figure 1, namely the base box 11, the PPE lining 12 and the coating portions 14a and 14b, forming the covering skin 14 of the panel. These elements are arranged in the same way.
- the PPE liner 12 comprises a coating surface 120 and, opposite it, means of attachment 13 to the base box 11 .
- the lining 12 of the panel 10 ' can be fixed to the base box 11 by any suitable fixing means allowing the interchangeability of the panel on the base box.
- the liner 12 can be fixed by means of a centering pin 13, secured to the liner 12 and projecting relative to the liner 12, intended to cooperate with a complementary orifice formed in the base box 11 .
- the covering surface 120 of the PPE lining is intended to be covered with a covering skin 14.
- the latter is composed of two adjacent covering portions 14a, 14b, for example a first portion upper 14a and a second lower portion 14b, these two portions may vary in appearance.
- the two adjacent covering portions 14a and 14b of the covering skin 14 are assembled on the covering surface 120 of the PPE lining 12, for example by gluing, to form the covering skin 14 of the panel.
- the upper 14a and lower 14b covering portions of the skin 14 each have a curved edge 140a, 140b cooperating with one another. More specifically, the curved edges 140a, 140b are arranged substantially perpendicular to the remains of the portions 14a and 14b and are assembled one against the other and arranged so as to project into a trench 20 made for this purpose in the thickness of the lining 12, that is to say towards the inside of the panel 10', so as to hide this connection.
- each covering portion respectively 14a, 14b, comprises first and second surface portions substantially transverse to each other, respectively a first surface portion which extends over the covering surface of the profile 12 and a second surface portion, forming the curved edge, which extends into the trench 20 formed in the thickness of the lining 12, these first and second surface portions being interconnected by a rounded connection, having a convex section in an arc of a circle, respectively 141a, 141b.
- the PPE liner 12 comprises a rigid insert 30, in injected plastic, embedded in the thickness of the PPE liner 12, in particular to provide stiffness in this region.
- a rigid insert 30 in injected plastic, embedded in the thickness of the PPE liner 12, in particular to provide stiffness in this region.
- the insert 30 implemented in the panel of the invention is remarkable in that it has an inverted pi shape in axial section. It comprises a base 31 embedded in the thickness of the PEE lining 12, opposite the covering surface 120 of the lining with respect to the trench 20, and a pair of wings 32, 33, parallel to each other. , projecting transversely from the base 31 and extending as far as the covering surface 120, this pair of wings 32, 33 constituting the side walls of the trench 20 formed in the thickness of the lining in which the respective curved edges 140a, 140b of the adjacent coating portions 14a, 14b of the covering skin.
- the respective free ends of the pair of wings 32, 33 are arranged flush with the surface of the lining 12 and delimit the free edges of the trench 20, opposite the base 31, the portion of which extending between the pair of wings 32, 33 defines the bottom of the trench 20.
- the base 31 extends continuously and substantially parallel to the covering surface 120 of the lining 12, over a certain non-zero distance on either side of the bottom of the trench 20, for example over a distance at least equal to the depth of the trench, so as to improve the rigidity provided to the assembly.
- the surface transition zone between the rigid plastic of the insert 30 and the expanded plastic of the liner 12 is strictly limited to the border, on the side opposite the trench 20, respective free ends of the pair of wings 32, 33 emerging flush with the surface of the lining 12.
- the respective free ends of the pair of wings 32, 33 define the free edges of the trench 20 to the right of which are formed the roundings of connection with a convex section in an arc of a circle, respectively 141a, 141b, connecting the respective curved edges 140a, 140b of the adjacent coating portions projecting into the trench 20 to the rest of these portions.
- the transition zone between the rigid plastic of the insert 30 and the expanded plastic of the liner 12 is strictly included in this shape change zone defined by the rounding of connection, so that it will not be perceived as being a defect in the visual appearance of the skin surface, in contrast to the injected plastic/PPE transition zone, referenced 19 in the case of the implementation of the insert 15, which extends over a substantially flat zone of the skin surface, at a significant distance from this zone of change in shape and therefore, which is perceived as a defect on the skin surface.
- the geometry of the insert 30 advantageously makes it possible to shift the injected plastic/PPE transition zone towards the trench 20, at the level of the rounded connection of the skin and thus, to significantly improve the visual perception of the panel 10' at the level of the junction region between the adjacent coating portions forming the skin.
