摘要： This invention relates to a heavy-load radial tire wherein metal cords having a single twist structure obtained by twisting 3 to 5 metal filaments having a filament diameter of 0.13 to 0.32 mm, and having an arithmetic-mean of elongations P1, 0.35 to 1.0 %, in the range of a load of 0.25 to 5 kgf/piece are disposed as a carcass ply in such a manner that the cord gap at the end portion of the carcass ply is at least 0.25 mm. This arrangement makes it possible to reduce drastically the tie weight, to avoid problems with workability for loose bead and the like, to improve breakage resistance at the end portion of the carcass ply, corrosion and fatigue resistance and anti-fretting property. At the same time, it is possible to improve drastically side scratch resistance of the radial tire (anti-cord break property). The radial tire of the invention may be designed to satisfy a specific relationship between the tensile strength TS of the metal filament and the filament diameter d in the range where load index in accordance with ISO 4209/1 is 121 or below and 122 or above so as to further improve various properties described above.
摘要翻译：在重载子午线轮胎中，金属帘线具有单一扭转结构。通过扭转具有丝直径的3至5个金属丝。为0.13〜0.32mm，并且具有伸长率P1的算术平均值。在0.25〜5kgf /片的载荷范围内的0.35〜1.0％作为胎体帘布层设置，使得胎体帘布层的端部处的帘线间隙为至少0.25mm。这种布置使得可以显着降低粘结重量，以避免松散珠等的可加工性问题，从而提高胎体帘布层端部处的抗断裂性，耐腐蚀性，耐疲劳性和抗微动性。同时，可以提高子午线轮胎的抗刮伤性（抗绳断裂性）。子午线轮胎可以被设计成满足金属丝的拉伸强度TS和丝直径之间的特定关系。 d在符合ISO 4209/1的负荷指数为121以下且122以上的范围内。

摘要： A seat back pad (14) is provided with a longitudinally extending groove (36), in which an insert wire (40) for fixing a seat skin thereon is buried. The insert wire (40) is provided at the sections thereof which are opposed to an air bag with bent portions (44), each of which are curved in the shape of the letter "C", a slub pad (46) being wound around an outer circumference of base part (44A) thereof. In this side air bag-carrying seat structure, the bend portions (44) of the insert wire (40) are extended diagonally in a rear inner portion of the seat back (10). Thus, the length of the portions of the insert wire which are buried in the seat back pad (14) is increased, and an ill influence upon the riding comfort is minimized.
