  • Collision determination system, occupant restraint system, and vehicle
    Patent number: 8825305
    Abstract: The invention provides an effective technique for appropriately restraining a vehicle occupant at the time of a side collision of a vehicle. An occupant restraint system mounted to a vehicle comprises a camera, a side impact sensor, an acceleration sensor, an ECU, and an airbag module. The ECU changes a threshold value setting for collision velocity at the time of a side collision of the vehicle according to whether or not a colliding object involved in the side collision of the vehicle is a pole-like object, and controls the airbag module based on the set threshold value.

  • Airbag device
    Patent number: 8814200
    Abstract: An airbag device includes an airbag, an inflator, a retainer and an airbag cover. The airbag is usually folded, and expands and develops in an emergency. The inflator supplies gas to the airbag. The retainer secures the airbag and the inflator. The airbag cover houses the airbag. The airbag cover has a plate-like part and an inner case. The plate-like part constitutes the interior surface of a vehicle. The inner case is disposed on the rear surface of the plate-like part and constitutes an expansion and development path for the airbag. The inner case has a plurality of retaining holes for retaining the retainer. The retainer has a roughly planar-shaped support body capable of being stored within the inner case and an annular belt-like body inserted into the retaining holes and attached to the support body.

  • SEAT BELT RETRACTOR AND SEAT BELT ASSEMBLY INCLUDING SAME
    Publication number: 20140224916
    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.

  • Curtain airbag device and vehicle
    Patent number: 8801030
    Abstract: In one form, a curtain airbag device is provided having a gas introduction portion that is folded so as to be disposed on a side surface of a folded body of a curtain airbag main body on a roof side portion side. When the vehicle is involved in a side collision or an overturn, an inflator discharges a gas, which is supplied to a curtain airbag, thereby causing the curtain airbag to start to be inflated. In this case, the gas from the inflator initially flows into the gas introduction portion so as to inflate the gas introduction portion. Thus, the inflating force of the folded body of the curtain airbag main body and the inflating pressure of the gas introduction portion are superposed each other so as to press a lower edge of a roof side garnish toward the inside of the vehicle cabin.

  • Restraint device
    Patent number: 8783725
    Abstract: When releasing a connection between a motor and a spool, the value of a drive voltage is increased at start-up of the motor. After the rotating shaft of the motor starts rotating, the value of the drive voltage is set to a minimum value necessary to maintain the rotation of the rotating shaft. By this means, it is possible to prevent the number of revolutions of the rotating shaft of the motor from increasing unnecessarily and reduce the sound produced from the motor.

  • Seat belt locking buckle and seat belt apparatus including seat belt locking buckle
    Patent number: 8746743
    Abstract: A seat belt locking buckle configured to allow a seat belt locking tongue to be stably and firmly latched and reduce the thickness of a seat belt locking buckle. When a tongue latch member is inserted into a seat belt locking buckle, an ejector is moved. Thus, a buckle latch member 13 becomes rotatable. Consequently, a slider moves along a plane that is parallel or substantially parallel to a plane of the motion of the tongue latch member and pushes a first latch guide portion of the buckle latch member. Thus, the buckle latch member is rotated from a non-latch position to a latch position. In this manner, the tongue latch member is latched by the buckle latch member.

  • Pretensioner, seatbelt retractor including the pretensioner, and seatbelt apparatus including the seatbelt retractor
    Patent number: 8720950
    Abstract: A ring gear 15 of a pretensioner 8 includes a plurality of levers 17 and one arc-shaped stopper 16 to allow force transmission members to smoothly move in a pipe, to facilitate setting of a stopper for stopping rotation of a ring gear, and to reduce the cost with a simple structure. During operation of the pretensioner 8, the levers 17 are sequentially pressed by balls 12a to rotate a pinion 19 and a spool in a seatbelt retracting direction. When the ring gear 15 rotates by a predetermined rotation amount, an outer peripheral edge 16c of the stopper 16 contacts and presses the opposing ball 12a. Since the ball 12a is thereby clamped between the stopper 16 and an inner peripheral surface 10d1 of a pipe I0, the ring gear 15 is stopped.
