Patent number: 10328893Abstract: A webbing for a passenger restraint belt forms a long passenger restraint belt to restrain a vehicle passenger. The webbing includes warp yarns and weft yarns. The warp yarns and weft yarns are woven so as to extend orthogonally to each other. The warp yarn includes at least one conductive yarn and non-conductive yarns. Anon-conductive yarn is thicker than the at least one conductive yarn.Type: GrantFiled: March 22, 2017Date of Patent: June 25, 2019Assignee: TAKATA CORPORATIONInventors: Sadayuki Shimazaki, Daichi Nemoto, Hiroki Terai

Patent number: 10207673Abstract: Provided are a seat belt retractor and a seat belt device with which it is possible to improve an occupant-restraining property and energy absorption characteristics. A seat belt retractor 1 including a spool 2 that winds up a webbing W for restraining an occupant, a shaft 3 inserted through an axial center of the spool 2, and a locking base 4 connected to the shaft 3 and capable of switching between a rotating state and a non-rotating state, further includes an energy absorption device 5 capable of changing an energy absorption amount according to a relative rotation speed between the spool 2 and the shaft 3, and a load adjustment member 6 that blocks or reduces load transmission when a load equal to or greater than a threshold is applied to the shaft 3 or the spool 2. The spool 2, the shaft 3, the locking base 4, the energy absorption device 5, and the load adjustment member 6 are serially connected.Type: GrantFiled: May 26, 2015Date of Patent: February 19, 2019Assignee: JOYSON SAFETY SYSTEMS JAPAN K.K.Inventors: Hayato Uchibori, Daichi Nemoto

Patent number: 10189439Abstract: Provided are a seat belt retractor and a seat belt device with which it is possible to improve energy absorption characteristics and a restraining property. The seat belt retractor includes a spool that performs winding of a webbing for restraining an occupant, a shaft inserted through an axial center of the spool, and a locking base connected to the shaft and capable of switching between a rotating state and a non-rotating state. The seat belt retractor further includes a load adjustment member disposed between the shaft and the locking base and that blocks or reduces load transmission in a case where a load equal to or greater than a threshold is applied to the shaft, and an energy absorption device disposed between the spool and the locking base and capable of changing an energy absorption amount according to a relative rotation speed between the spool and the locking base. The energy absorption device is connected in parallel with the load adjustment member.Type: GrantFiled: June 23, 2015Date of Patent: January 29, 2019Assignee: JOYSOFT SAFETY SYSTEMS JAPAN K.K.Inventors: Hayato Uchibori, Daichi Nemoto

Patent number: 10173638Abstract: To provide an energy absorbing device, a seat belt retractor, and a seat belt apparatus that can vary an energy absorbing amount depending on increase and decrease of rotation speed between relatively rotating objects and can improve durability. An energy absorbing device includes a casing connected to one object, an annular first clutch disc disposed in the casing, an annular second clutch disc disposed in the casing, and an annular clutch plate connected to the other object and having an engaging surface that faces both the first clutch disc and the second clutch disc, wherein the engaging outer teeth of the first clutch disc and the engaging inner teeth of the second clutch disc alternately engage with the engaging teeth of the clutch plate so as to absorb an energy generated by a relative rotation between one object and the other object.Type: GrantFiled: February 23, 2015Date of Patent: January 8, 2019Assignee: JOYSON SAFETY SYSTEMS JAPAN K.K.Inventors: Hayato Uchibori, Daichi Nemoto
