Patent number: 9539980Abstract: A seat belt retractor that functions to cancel both a function of a vehicle sensor and a function of a webbing sensor on a predetermined condition with a simple structure and a small number of components. When a seat belt is fully retracted, a cam follower of a first lever comes into contact with a second cam portion of a cam plate. An actuator pressing portion of the first lever presses an actuator of a vehicle sensor to a non-operation position. The function of the vehicle sensor is thereby cancelled. Further, when an engaging claw of a second lever separates from a ratchet tooth of a ring gear, the ring gear is allowed to rotate in a seat belt withdrawing direction. Therefore, the function of the webbing sensor is cancelled.Type: GrantFiled: March 19, 2012Date of Patent: January 10, 2017Assignee: TAKATA CORPORATIONInventors: Kenji Osada, Hirokazu Yoshioka

Patent number: 8950819Abstract: During an emergency, in one form of a retractor having a spool, external teeth of a pawl provided at a spool right side end are made to mesh with some of internal teeth provided on a frame, and, with load acting on a seat belt, a spool left side end is brought into contact with a spool pushing portion. Since the spool left side end tends to be moved further in a direction of seat belt load with the load acting on the seat belt, the spool pushing portion pushes the spool left side end, whereby some of external teeth come into contact with internal teeth provided on the frame and fit deeply into gaps between adjacent ones of the internal teeth. Thus, some of the external teeth of the spool effectively come into mesh with the respective internal teeth of the frame with a simple movement of the spool.Type: GrantFiled: June 3, 2011Date of Patent: February 10, 2015Assignee: Takata CorporationInventors: Hirokazu Yoshioka, Kenji Osada, Takashi Sesaki

Patent number: 8864173Abstract: A seat belt retractor is provided that realizes the proper meshing between a plurality of internal teeth and external teeth with a simple movement of a spool. In the case of an emergency, external teeth of a pawl provided at a spool right side end mesh with internal teeth provided on a frame, and, with load acting on a seat belt, a spool left side end contacts a spool guide. Since the spool left side end tends to move further in the direction of seat belt load, the spool guide brings one external tooth at the spool left side end into contact with one target internal tooth provided on the frame. Hence, some of the spool external teeth are made to mesh properly with the respective internal teeth. Thus, some of the spool external teeth effectively mesh with the respective frame internal teeth with simple movement of the spool.Type: GrantFiled: June 3, 2011Date of Patent: October 21, 2014Assignee: Takata CorporationInventors: Hirokazu Yoshioka, Kenji Osada, Takashi Sesaki

Patent number: 7874503Abstract: An electrostatically atomizing device capable of instantly giving an electrostatically atomizing effect without requiring a water tank. The electrostatically atomizing device includes an emitter electrode, an opposed electrode opposed to the emitter electrode, a water feeder configured to give water on the emitter electrode, and a high voltage source configured to apply a high voltage across said emitter electrode and said opposed electrode to electrostatically charge the water on the emitter electrode for spraying charged minute water particles from a discharge end of the emitter electrode. The water feeder is configured to condense the water on the emitter electrode from within the surrounding air, enabling to supply the water on the emitter electrode in a short time without relying upon an additional water tank. Thus, an atomization of the charged minute water particles can be obtained immediately upon use of the device.Type: GrantFiled: April 1, 2005Date of Patent: January 25, 2011Assignee: Panasonic Electric Works Co., Ltd.Inventors: Osamu Imahori, Toshihisa Hirai, Kishiko Hirai, legal representative, Akihide Sugawa, Fumio Mihara, Shousuke Akisada, Tomoharu Watanabe, Hirokazu Yoshioka, Kentaro Kobayashi, Shinya Murase, Kouichi Hirai, Junji Imai
