る。Recently, Japanese Patent Publication No. 54-20732 and Japanese Patent Laid-Open No. 60-261474 disclose energy absorbing belts as shock absorbing belts. The energy absorbing belt disclosed in Japanese Patent Publication No. 54-20732 uses two or more different yarns as the warp yarns of the belt, and at least one of them is an aromatic polyamide fiber. Alternatively, an aromatic polyhydrazide polyamide copolymer fiber is used.

分に保護拘束することができない欠点を有していた。In the seat belt of the conventional seat belt device, even if the breaking elongation in the longitudinal direction of the seat belt is as low as 3 to 8%, the winding shaft of the seat belt retractor can be prevented. Since the extension occurs after the belt withdrawal rotation is stopped, the initial restraint of the occupant is delayed, and the occupant cannot be sufficiently protected and restrained.

Has been done. Although the primary rising is obtained with warp yarns having a lower weaving shrinkage ratio than the normal weaving shrinkage ratio, although the weaving structure is low even though the weaving shrinkage ratio is low, elongation occurs, and the primary rising, that is, the initial restraint of the occupant. It had the drawback of being delayed and of being unable to reduce the injury value (HIC).

This gave different elongation properties. This mechanical pretreatment is a mechanical process of stretching, shrinking and / or twisting,
It is set to a predetermined reference expansion value.

Therefore, the shock absorbing belt cannot be easily formed, and there is a drawback that the cost increases, and the initial restraint of the occupant is poor due to the stretching of the belt, and the energy cannot be sufficiently absorbed, which is added to the occupant. The impact could not be sufficiently mitigated.
