Abstract
(EN)
A land section (3) formed on a tread surface (1) has formed therein a closed sipe (5) comprising at least three cuts (4) which extend in the radial direction from an imaginary axis (2) as the center and terminate within the land section (3), said imaginary axis (2) extending in the direction of the depth of the land section (3). The cuts (4) are helically twisted about the imaginary axis (2) along the depth direction in such a manner that the angle (θ) of the twist is set to be greater than or equal to 10˚ and less than 135˚ and that the width of the cuts (4) or the length of the cuts (4) in the radial direction is set to be greater on the tread surface (1) side than on the bottom surface side.
(FR)
Dans une section partie de contact (3) formée sur une surface de bande de roulement (1) est formée une lamelle fermée (5) comprenant au moins coupes (4) qui s'étendent dans la direction radiale depuis un axe imaginaire (2) comme centre et se terminent dans la section partie de contact (3), ledit axe imaginaire (2) s'étendant dans la direction de la profondeur de la section partie de contact (3). Les coupes (4) sont hélicoïdalement tordues autour de l'axe imaginaire (2) le long de la direction de profondeur d'une manière telle que l'angle (θ) de la torsion est défini pour être supérieur ou égal à 10 ° et inférieur à 135 ° et que la profondeur des coupes (4) ou la longueur des coupes (4) dans la direction radiale est définie pour être plus importante sur le côté surface de bande de roulement (1) que sur le côté surface inférieure.
