Patent number: 11807185Abstract: An airbag includes a chamber that expands due to gas being introduced at a time of deployment and a non-expanding area that does not expand at the time of deployment, in which the airbag deploys by gas being introduced into the chamber. A first portion inside the chamber that is located around the non-expanding area includes a tip end portion that is closed, and at the time of deployment, the tip end portion applies a load to and becomes in contact with a second portion of the chamber that is located around the non-expanding area and that faces the tip end portion.Type: GrantFiled: September 13, 2022Date of Patent: November 7, 2023Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yuya Motoji, Kennosuke Kariya, Takafumi Ogasawara, Masahiro Urago, Makoto Omura

Patent number: 6675478Abstract: Balls are supported between the spherical inner race 5 and the outer race 6 which surrounds one potion of the inner race 6 through the resiliently transformable shell-like retainer 7. By making the inner race 5 and outer race 7, which influence the bearing precision greatly, to be formed in a unit respectively, the bearing precision is increased. For reference, although the retainer is divided, the retainer 7 bears merely the ball holding function and its transformation and the position relation in assembling state do not influence the bearing precision.Type: GrantFiled: December 7, 2001Date of Patent: January 13, 2004Assignee: Minebea Co., Ltd.Inventors: Gen Sasaki, Shinichi Akao, Kennosuke Kariya

Patent number: 6612744Abstract: A lock structure of a spherical bearing restrains an outer race from turning relative to a housing with a simple structure. It is provided with protruding portions formed on a periphery of one side of a bearing hole of the housing. A flange is formed on one side of the outer race. Meanwhile notches (engagement portions) are formed in the flange, which are brought into engagement with the protruding portions. An annular V-shaped groove (staking groove) formed in the other side of the outer race is staked. With such a simplified structure, the spherical bearing can be locked to the housing while being restrained from turning relative thereto.Type: GrantFiled: July 11, 2001Date of Patent: September 2, 2003Assignee: Minebea Co., Ltd.Inventors: Gen Sasaki, Makoto Fujino, Kennosuke Kariya

Patent number: 6502993Abstract: A sealing system of a spherical bearing is constituted in such a manner that annular seal grooves are provided on an inner spherical surface of an outer race with a given space from an edge of the spherical surface, seals are fit in the seal grooves and abut against a spherical surface of an inner race. With this construction, the sealing system of the spherical bearing is easily formed with a high sealing function by tightly abutting the seals fitted in the grooves to the spherical surface of the inner race.Type: GrantFiled: July 26, 2001Date of Patent: January 7, 2003Assignee: Minebea Co., Ltd.Inventors: Gen Sasaki, Makoto Fujino, Kennosuke Kariya

Patent number: 6349470Abstract: On the periphery surface of the outer race, the stepped portion is formed, and on one side of the race retention hole formed on the housing, a screw portion is provided coaxially with the race retention hole, in which the setscrew is screwed and tightened. Retention of the front surface of the setscrew makes the end face of the stepped portion, pressed against the snap ring retained with the annular groove, formed on the race retention hole. Since the outer race is clamped by the setscrew and the snap ring and the gap between the end face of the outer race and the setscrew, and the snap ring becomes null, the outer race is securely retained in the axial direction.Type: GrantFiled: June 27, 2000Date of Patent: February 26, 2002Assignee: Minebea Co., Ltd.Inventors: Gen Sasaki, Shinichi Akao, Kennosuke Kariya

Patent number: 6325544Abstract: On one side of the race retention hole 2, a screw portion 3 is formed, and on one side of the periphery surface of the outer race 4 an outer conical portion 5 is formed, and with the race retention hole 2, the periphery surface of the outer race 4 supporting the spherical surface 9a of the outer race 9 is retained, the stopping screw 8 is formed on with the inner conical portion 7 to be fit with the periphery surface 5a of the outer conical portion 5 is screwed in the screw portion 3 and tightened. Thus, by tightening the stopping screw 8, the periphery surface 5a of the outer conical portion 5 is pressed with the inner circumference 7a of the inner conical portion 7 and the contact surface pressure between the inner circumference surface 4b of the outer race 4 and the spherical surface 9a of the inner race 9 is increased, so that by regulating the tightening force of the stopping screw 8 the sliding torque of the spherical bearing is easily adjusted.Type: GrantFiled: July 31, 2000Date of Patent: December 4, 2001Assignee: Minebea Co., Ltd.Inventors: Gen Sasaki, Shinichi Akao, Kennosuke Kariya
