  • Patent number: 8950819
    Abstract: 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.

  • 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.

  • Patent number: 8678509
    Abstract: To effectively operate a pretensioner using a plurality of balls and an energy absorption mechanism, to simplify the structure of an exhaust passage in the pretensioner, and to facilitate the working process of the exhaust passage. A pretensioner 15 includes a plurality of balls 20 serving as force transmission members and a piston 21 in a pipe 17. A piston body 21a of the piston 21 includes a shaft portion 21c and a substantially hemispherical head portion 21d. The piston body 21a is provided with an exhaust hole 21e extending in the axial direction and exhaust grooves 21f communicating with the exhaust hole 21e that define an exhaust passage. The exhaust grooves 21f prevent the exhaust hole 21e from being closed even if the head portion 21d of the piston 21 contacts the ball 20. Since the exhaust hole 21e and the exhaust grooves 21f are simply provided in the piston body 21a formed as a single member, the structure of the exhaust passage is simple, and working of the exhaust passage is easy.

    Abstract: A webbing retractor is provided that reduces the amount of webbing that is pulled-out after operation of a pretensioner mechanism. In a webbing retractor 10, a lock pawl 78 is set in a non-meshable state in which it cannot mesh with a lock gear 26. At a time when a pretensioner mechanism 34 operates and a clutch plate 42 rotates in a take-up direction, a lock stopper 86 rotates together with the clutch plate 42 and releases engagement with the lock pawl 78. Therefore, the lock pawl 78 is rotated by a compression coil spring 70 and changed to a meshable state. In this way, immediately after rotational force in a pull-out direction is applied to the lock gear 26 due to load from a vehicle occupant after operation of the pretensioner mechanism 34, the lock pawl 78 meshes with the lock gear 26, and pulling-out of a webbing 20 is impeded. Therefore, an amount of the webbing 20 which is pulled-out can be reduced.

  • Patent number: 6824222
    Abstract: A seat belt system (10) includes a lap belt (60) including a first portion (74) and a second portion (85). A retractor (76) includes a spool (96) rotatable about an axis (160). The first and second lap belt portions (74, 85) are secured to the spool (96). The spool (96) is biased to rotate in a first rotational direction to wind the first and second portions (74, 85) onto the spool. The first and second portions (74, 85) when tensioned urge the spool (96) to rotate in a second rotational direction opposite said first rotational direction to unwind the first and second portions from the spool. A locking mechanism (170) is actuatable to lock the spool (96) against rotation in the second rotational direction. First and second web grabbing devices (180, 182) are actuatable to clamp onto the first and second portions (74, 85) when the locking mechanism (170) is in the locked condition.

  • Patent number: 6786551
    Abstract: A seat latching assembly for a vehicle includes a seatback having first and second sides. A first latch is provided for latching the first side of the seatback to a portion of a vehicle, the first latch being operable between a latched position and an unlatched position. A second latch is provided for latching the second side of the seatback to another portion of the vehicle, the second latch being operable between a latched position and an unlatched position. A mechanism is operatively connected to the first and second latches, and is movable between a locked position and an unlocked position. When one of the first and second latches is in the unlatched position, the mechanism is prevented from moving into the unlocked position, and when the first and second seat portions are both in their latched positions, the mechanism is permitted to be moved into the unlocked position.

  • Patent number: 6659505
    Abstract: A system and device for managing the restraints available for vehicle occupants that uses fluidic torque conversion to provide an adaptive variable load limiting for the primary occupant safety restraint. The fluidic torque conversion of this invention can be variably controlled through the use of an electro/mechanical flow control device. The flow control is preferably coupled to one or more sensors, including occupant weight, occupant position, seat position, low “g”, high “g”, and belt displacement/latching sensors. This invention is adapted to be responsive to the vehicles interior safety devices, including front air bags, side air bags, seat back pivots, head rests, collapsible steering wheel, and positioning of the dash board and/or vehicle instrumentation. This invention is a re-usable system.

  • Patent number: 6659548
    Abstract: The vehicle seat of a vehicle has a seat carrier with a side part, a buckle of a safety belt positioned thereon and a vertically adjustable underframe. The underframe is provided with a sector gear. An engaging element is arranged on the seat carrier and is designed to cooperate with the sector gear. During normal, non-accidental circumstances, the sector gear is in a rest position in which the engaging element is free from the sector gear. The buckle is connected to an upper end of a rope that cooperates with the engaging element. In an accident situation the engaging element engages the sector gear. A tightening unit for the belt has a driving cylinder. The rope is deflected in its direction at a point of deflection. A lower portion of the rope runs substantially in longitudinal direction of the side part. The other end of the rope is arranged on the driving cylinder. A holder for the tightening unit is provided on the side part.

  • Patent number: 6523771
    Abstract: In a webbing retractor, when a pawl engages with an internal tooth, a lock plate is guided, via a V gear, to a position at which engagement with a ratchet tooth is possible, and thereafter, the lock plate self-locks. When the V gear reversely rotates by a predetermined amount in accordance with this self-locking, engagement of the pawl and the internal tooth is cancelled. An engagement surface of the internal tooth corresponds to a locus of swinging of the pawl. Engagement with the pawl is cancelled at a smallest V gear reverse rotation angle.

  • Publication number: 20010002087
    Abstract: The helmet restraint system of the invention secures the helmet of a driver or passenger occupant of a vehicle, such as a race car, to the structural chassis, body, or frame of the vehicle, independent of the shoulder harness or seatbelt. The system provides a head restraint system which reduces the potentially injurious forces to the neck and head during a high-deceleration event, particularly a frontal collision. The helmet restraint belt system comprises a restraint belt assembly which spans between an anchor point on the vehicle chassis/body and a belt receiving latch mounted to the driver's helmet. The belt is preferably retractable and pre-tensioned by means of a collision or inertially-lockable belt tensioner. The helmet restraint system allows the driver to have unrestricted head movement during normal driving, but restrains the helmet and head during the impact of a collision by locking the belt against further extension.
