[Object] To provide a seat belt device which exhibits good smoothness even at a low temperature of about &#x2212;30&#xb0; C., which exhibits a small reduction in smoothness even after repeated use for a long period of time, or after use at a high temperature (80&#xb0; C.), and which has good webbing retracting performance. [Solution] A seat belt device includes a webbingformed by applying a webbing treatment agent to a webbing base material, a retractorfor retracting the webbing, and an anchor memberthrough which the webbingis slidably hung. The webbing treatment agent is characterized by containing as an essential component a hydrocarbon-based synthetic oil with a viscosity of 35 to 100,000 mPa&#xb7;s at &#x2212;30&#xb0; C.

Seat belt device

To improve wear resistance of a woven belt and a seatbelt device including the woven belt A woven belthas a structure formed by weaving a plurality of warp yarnsextending in a substantially longitudinal direction of the belt and a plurality of weft yarnsextending in a substantially transverse direction of the belt. At least one of the warp yarnsand the weft yarnsis a fiber bundle containing highly contractible synthetic fiber yarns (e.g., yarns containing a low-melting-point filament componenthaving a relatively low melting point and a high-melting-point filament componenthaving a relatively high melting point) so that the strength of the fiber bundle can be increased, and the wear resistance of the woven beltas a whole can be improved.

Woven belt and seatbelt device

The disclosed woven belt may include first filament yarn bundles extending in a substantially longitudinal direction of a webbing and second filament yarn bundles extending in a substantially transverse direction of the webbing. At least one of the first filament yarn bundles and the second filament yarn bundles may comprise filament yarn bundles containing middle-shrinking synthetic filament yarns.

Woven belt

In a woven belt and a seat belt apparatus using the same, it is an object to improve the abrasion resistance thereof. A woven beltis made by weaving warp threadextending in substantially the longitudinal direction of webbing and weft threadextending in substantially the width direction of the webbing. Employed as at least either of the warp threadand the weft threadis fiber bundle containing thermal adhesion yarns (for example, each comprising a low melting point filament componenthaving a relatively low melting point and a high melting point filament componenthaving a relatively high melting point), thereby improving the strength of the fiber bundle and thus improving the entire abrasion resistance of the woven belt

Woven belt and seat belt apparatus

The disclosed webbing for a passenger restraint belt may include warp yarns and weft yarns made of synthetic filaments and woven so as to extend orthogonally to each other. At least one of the warp yarns and the weft yarns may be formed using synthetic filaments comprising first filaments and second filaments. Also, the second filaments may be provided in the first filaments and have a melting temperature lower than that of the first filaments. The synthetic filaments may be high shrinking synthetic filaments which are contracted at a dimensional shrinkage rate of 20% to 60% after the second filaments are melted under conditions of 150&#xb0; C. or more for 180 seconds or more. The webbing may have a weight of 60g/m or less, a tensile strength of 25 kN or more, and a retention rate after hexagonal bar abrasion of 70% or more.
