Definitions
- the present invention relates to a tire for a motor vehicle having a marking and a particular texture surrounding this marking.
- the sidewalls of tires have a large amount of markings intended to provide technical and legal information or to enable consumers to distinguish the origin of the product.
- EP2204206 discloses a texture present on the outer surface of a tire sidewall. This texture comprises a plurality of strands regularly distributed in this texture.
- US 2008/0283169 discloses a tire of rubber material comprising a flank and a marking formed on this sidewall.
- the marking is arranged in a housing made hollow in the sidewall. This marking is protruding from the bottom of the housing so that it has good visibility on the sidewall of the tire.
- Thread of a tire means a quantity of rubber material defined by side surfaces and by two major surfaces, one of which is intended to come into contact with a roadway when the tire is rolling.
- Standard wall of a tire means a side surface of the tire disposed between the tread of the tire and a bead of the tire.
- Marking on a sidewall of a tire means indications on that side intended to give technical and legal information or to enable consumers to distinguish the origin of the product.
- Textture means an organized arrangement of a plurality of elements, all or part of the elements of the arrangement being the repetition of the same basic element, for example, a strand or a lamella.
- String means a filamentary element whose height is at least equal to twice the diameter of a disc of the same surface as an average section of this strand.
- Medium section of a strand means the average of the sections measured at regular intervals from the base of the strand to the top of this strand.
- “Slat” means elongated strands having a length at least twice their height.
- the term “mean width” of a coverslip means the average of the widths measured at regular intervals from the base of the lamella to the top of this lamella.
- the tire made of rubber material comprises a flank and a protruding marking from this sidewall.
- the tire has a texture.
- the texture comprises a plurality of protruding strands from the sidewall, these strands being distributed at a density of at least five strands per square millimeter (mm 2 ), each strand having a mean section of between 0.0007 mm 2 and 0 , 06 mm 2 and / or said texture comprising a plurality of lamellae substantially parallel to one another protruding from the sidewall, the pitch of the lamellae being at most equal to 0.5 mm, each lamella having an average width of between 0.03 mm and 0.3 mm.
- the texture protrudes from the sidewall of the tire, this texture surrounding all or part of the marking.
- the texture surrounding the marking, and formed by strands or lamellae provides several advantages. On the one hand, this texture can "trap" all or part of the incident light rays that meet the sidewall. This makes it possible to give a darker appearance around the marking and consequently to improve its contrast and therefore its visibility with respect to the rest of the sidewall. On the other hand, this particular texture makes it possible to obtain a pleasant touch on the side, of the "velvet” type. In addition, the texture used has hydrophobic properties so that the evacuation of water, dust or mud around the marking is facilitated. In addition, the texture surrounding the marking generally has a greater durability. Indeed the marking protects the texture against certain types of wear, for example the wear caused by sidewalk gratings.
- the strands of the texture extend in height at the same level as the marking of the sidewall. In this way, these strands, respectively these strips, extend the sidewall of the tire at the same level as the marking. The overall visual impression of the sidewall of the tire is thus improved.
- the strands of the texture extend in height to a level lower than that of the marking.
- the strands of the texture are equal to the marking.
- the emergent parts of the strands, respectively the lamellae of the texture have a certain flexibility because of their great slenderness. When the texture undergoes friction forces, these strands, respectively these lamellae deform by absorbing part of these friction forces. In this way, the marking is protected against wear and ensures greater durability. In addition, the fact that the strands, respectively the lamellae of the texture, protrude beyond the sidewall of the tire, generally improves the tactile effect of the texture.
- a portion of the strands of the texture, respectively a portion of the lamellae of the texture exceed the marking and another part of these strands, respectively of these lamellae are at a lower level with respect to this marking.
- the marking includes a raised edge relative to the rest of this marking. In this way, the contrast between the marking and the texture, and therefore the visibility of this marking on the sidewall of the tire, is further improved.
- the texture extends from the marking over a width L of between 0.5 mm and 50 mm.

- Figure 7 shows the marking of Figure 1, according to a particular embodiment
- FIG. 8 represents a schematic view of a texture surrounding the marking of FIG. 1 and comprising strands
- Figure 9 shows a schematic view of a texture surrounding the marking of Figure 1 and having slats.
- FIG. 8 shows a sidewall 3 of a tire 1.
- This sidewall comprises a marking 5, which here has the shape of the letter O.
- the tire further comprises a texture 9 surrounding the marking 5.
- the texture 9 alternatively surrounds all the marking 5.
- this texture 9 surrounds only part of this marking 5.
- This texture 9 comprises a plurality of strands 11, as shown in FIG. 8.
- the strands 11 have a overall conical shape with a section decreasing in the Hb height of these strands. More particularly, the average section of each strand, corresponding to the average of sections S measured at regular intervals from the base of the strand, is between 0.0007 mm 2 and 0.06 mm 2 .
- the strands are distributed at a density of at least five strands per square millimeter.
- the texture 9 comprises a plurality of lamellae 13, as shown in FIG. 9.
- the lamellae 13 have a generally triangular section and the average width of each lamella, corresponding to the average widths 1 measured at regular intervals in the height Hl of the blade, is between 0.03 mm and 0.3 mm.
- the lamellae 13 are substantially parallel to each other and the pitch P of the lamellae is at most equal to 0.5 mm.
- the texture 9 comprises a combination of strands 11 and slats 13.
- the texture 9 extends from the marking 5 over a width L between 0.5 mm and 50 mm.
- FIG. 2 shows a sectional view of the texture surrounding the marking 5 according to a first embodiment of the invention.
- This texture may comprise strands 11 and / or lamellae 13.
- the strands 11 of the texture, respectively the lamellae 13 of the texture extend at the same level as the marking 5, that is to say that is to say that the vertices of these strands 11, respectively the vertices of these strips 13 are at the level 6 of the upper part of the marking 5.
- the strands 11 of the texture, or the strips 13 of the texture extend in height at a level lower than that of the marking 5, ie these strands 11 or slats 13 are set back from the level 6 of the marking.
- the strands 11 of the texture, or the strips 13 of the texture exceed the marking 5, that is to say that the tops of these strands 11, respectively the vertices of these strips 13 exceed the level 6 of the upper part of the marking 5.
- the strands 11 and the strips 13 respectively flex, as can be seen in FIG. 5, absorbing all or part of these friction.
- a portion of the strands 11 of the texture, respectively a portion of the slats 13 of the texture beyond the marking 5 and another part of these strands 11, respectively of these lamellae 13 are recessed with respect to this marking 5.
- at least 20% of the strands 11, respectively lamellae 13 exceed the marking 5.
- the marking 5 comprises a raised edge 15 relative to the rest of this marking.
- the sidewall of the tire may, for example, include other markings not having around them a texture as described in the invention.
- the texture may only partially surround them.
