Patent number: 8419066Abstract: [Object] To provide a seat belt device which exhibits good smoothness even at a low temperature of about ?30° 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° C.), and which has good webbing retracting performance. [Solution] A seat belt device includes a webbing 12 formed by applying a webbing treatment agent to a webbing base material, a retractor 11 for retracting the webbing 12, and an anchor member 13 through which the webbing 12 is 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·s at ?30° C.Type: GrantFiled: December 15, 2009Date of Patent: April 16, 2013Assignee: Takata CorporationInventors: Sadayuki Shimazaki, Itsuo Tabayashi

Patent number: 7799709Abstract: To improve wear resistance of a woven belt and a seatbelt device including the woven belt A woven belt 101 has a structure formed by weaving a plurality of warp yarns 102 extending in a substantially longitudinal direction of the belt and a plurality of weft yarns 103 extending in a substantially transverse direction of the belt. At least one of the warp yarns 102 and the weft yarns 103 is a fiber bundle containing highly contractible synthetic fiber yarns (e.g., yarns containing a low-melting-point filament component 306 having a relatively low melting point and a high-melting-point filament component 307 having a relatively high melting point) so that the strength of the fiber bundle can be increased, and the wear resistance of the woven belt 101 as a whole can be improved.Type: GrantFiled: November 22, 2006Date of Patent: September 21, 2010Assignee: Takata CorporationInventors: Sadayuki Shimazaki, Itsuo Tabayashi

Patent number: 7662734Abstract: In a woven belt and a seat belt apparatus using the same, it is an object to improve the abrasion resistance thereof. A woven belt 101 is made by weaving warp thread 102 extending in substantially the longitudinal direction of webbing and weft thread 103 extending in substantially the width direction of the webbing. Employed as at least either of the warp thread 102 and the weft thread 103 is fiber bundle containing thermal adhesion yarns (for example, each comprising a low melting point filament component 206 having a relatively low melting point and a high melting point filament component 207 having a relatively high melting point), thereby improving the strength of the fiber bundle and thus improving the entire abrasion resistance of the woven belt 101.Type: GrantFiled: November 22, 2006Date of Patent: February 16, 2010Assignee: Takata CorporationInventors: Sadayuki Shimazaki, Itsuo Tabayashi

Patent number: 7563735Abstract: 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° 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.Type: GrantFiled: November 20, 2006Date of Patent: July 21, 2009Assignee: Takata CorporationInventors: Sadayuki Shimazaki, Itsuo Tabayashi
