  • Patent number: 9637084
    Abstract: A webbing take-up device is obtained capable of restricting movement of a clutch member in the axial direction of a second gear. In the webbing take-up device, a movement prevention portion is formed, on a rotor side, at an intermediate bottom portion of a large gear portion, and a clutch spring attached to the rotor abuts the movement prevention portion, thereby preventing any movement of the clutch spring further to the intermediate bottom portion side. Movement of the clutch spring in the axial direction of the rotor can accordingly be suppressed, enabling movement of the clutch spring in the axial direction of the rotor to be restricted.

  • Patent number: 9610920
    Abstract: In a pretensioner mechanism of a webbing take-up device, a sealing member seals a communicating hole of a piston. When a force limiter mechanism is operated and rotating of a spool in a pull-out direction is allowed, the piston is moved to an upper side in a state in which the sealing member is pressed and contacted against a cylinder. As a result, the sealing member is turned and the sealing of the communicating hole by the sealing member is released. In consequence, a number of components may be reduced and assembly characteristics of the pretensioner mechanism may be improved.

  • Patent number: 9592791
    Abstract: A vehicle seatbelt apparatus includes a seatbelt web wrapped in a reel around a motor-rotated shaft. A latch is selectively engageable with the reel to lock a seatbelt retractor from movement in one direction while allowing movement of the retractor under motor rotation of the shaft in response to pre-crash vehicle braking deceleration, a vehicle downhill angle or a vehicle lateral “g” force exceeding a threshold. When a retractor locked position is detected, the motor is activated to retract the seatbelt web for a predetermined time period to urge the passenger toward a center upright position in a vehicle seat.

  • Patent number: 9428148
    Abstract: In a webbing take-up device, a cylinder includes a housing portion that houses a piston and a guide portion that extends from one end portion in length direction of the housing portion. A pinion is rotatably supported at the guide portion. The piston is guided by the guide portion. A member that houses the piston and a member that rotatably supports the pinion do not accordingly need to be separately provided. An increase in number of components can therefore be suppressed. Positioning of the piston and the pinion can be respectively determined by the cylinder due to the piston and the pinion being provided to the cylinder. Good positioning precision between the piston and the pinion is thereby enabled compared to a case where separate members are used to house the piston and to rotatably support the pinion.

  • Patent number: 9290152
    Abstract: [Object] Quietness is to be more effectively improved, without compromising stability in power transmission. [Solution] An annular internal gear member 24 is formed of a noise suppressing material having lower strength than a metal. A deformation restricting portion 22d of an annular flange shape is formed along an outer circumferential edge of a carrier 22. Accordingly, when a planetary gear mechanism is operating the internal gear member 24 is partially deformed so as to protrude radially outward of the annular shape. At this point, the protruding deformed portion of the internal gear member 24 abuts against an inner circumferential surface of the deformation restricting portion 22d. Therefore, deformation of the internal gear member 24 is effectively restricted.
