Abstract: A webbing retractor has two torque transmitting routes for taking-up, such that rapid and reliable taking-up, and gentle taking-up are possible. When an engaging claw of a pawl restricts rotation of a ratchet plate, due to planetary gears rotating around a sun gear, rotation is transmitted from a drive gear to a carrier plate. On the other hand, when restriction of rotation of the ratchet plate is released, a clutch spring tightens around a tube portion of the carrier plate while rotation of the drive gear pulls one peripheral direction end of the clutch spring in a direction of rotation thereof. Frictional resistance between the tube portion and the clutch spring is increased, and rotation is transmitted from the drive gear to the carrier plate.

Abstract: A seat belt retractor is provided in which two winding performances are achieved while reduced power consumption of a motor and simplified control of the motor are also achieved. A clutch gear is meshed with a carrier gear by rotation of a motor in the normal direction. Accordingly, a low reduction ratio power transmission mode is set so that a seat belt is wound up at a high speed and with low torque. As slack of the seat belt is removed and the belt load increases, the clutch pawl becomes possible to be engaged with the internal gear. As the motor current increases and exceeds a preset value, the motor rotates reversely so that the clutch gear separates from the carrier gear. Therefore, a high reduction ratio power transmission mode is set so that the belt is wound up at a low speed and with high torque.

Abstract: An electric retractor extracts and retracts a seat belt in response to tension in the seat belt. The electric retractor may include a spool rotatably attached to a retractor frame. A seat belt is wound on the spool. The spool is rotated by a motor via a worm gear system that permits limited axial motion of the worm, but generally prevents the motor from being back-driven by tension in the seat belt to prevent forced seat belt extraction. The gear system may also cut off power to the motor in the event of excessive seat belt tension to prevent further payout of the seat belt. A senses tension in the seat belt and activates the motor to retract or extract the seat belt from the retractor. An emergency control system may override the web guide control in response to abnormal vehicle dynamics to provide reversible pre-crash pretensioning and/or crash pretensioning.

Abstract: A webbing retractor which, by causing relative rotation between a prime mover rotating body and a rotating disc, connects the prime mover rotating body and a driven shaft which is connected to a take-up shaft of a webbing belt. A planet gear is pivotally supported at a plate having a braking piece and meshes with a sun gear. The plate is supported so as to be swingable around the sun gear. When the sun gear is driven to rotate at greater than a predetermined speed, the planet gear begins to circle around the sun gear against urging force of a spring attached to the plate, and makes the plate rotate such that the braking piece slidingly contacts the friction ring. Due to this braking, the rotating disc connected to the friction ring rotates relative to the prime mover rotating body.

Abstract: A webbing retractor has two torque transmitting routes for taking-up, such that rapid and reliable taking-up, and gentle taking-up are possible. When an engaging claw of a pawl restricts rotation of a ratchet plate, due to planetary gears rotating around a sun gear, rotation is transmitted from a drive gear to a carrier plate. On the other hand, when restriction of rotation of the ratchet plate is released, a clutch spring tightens around a tube portion of the carrier plate while rotation of the drive gear pulls one peripheral direction end of the clutch spring in a direction of rotation thereof. Frictional resistance between the tube portion and the clutch spring is increased, and rotation is transmitted from the drive gear to the carrier plate.

The hose reel is connected to a rotatable water wheel having vertically-oriented blades disposed around its circumference. During storage, the hose of the pool cleaner is wrapped around the hose reel. To move the hose from the storage position into the pool, a stream of water from a blow out jet nozzle tangentially swipes the coiled hose and is directed at a cleaner head attached to the hose. The water flushes the cleaner head into the pool and rotates the hose reel in a first direction, causing the hose to unwind and travel into the pool.

Abstract: A flexible member sensor for detecting motion and tension of a flexible member includes a rigid member pivotally connected to a base, in contact with the flexible member. A sensor detects pivotal motion of the rigid member in response to movement of the flexible member. The sensor may provide a corresponding signal to a motion control system that adjusts the tension of the flexible member accordingly. In one implementation, the flexible member sensor is integrated with a feedback control system for an electric seat belt retractor that includes a feedback control loop. The flexible member sensor measures tension in seat belt webbing retained by the retractor. A motor coupled to a servo amplifier rotates a spool of the electric retractor to extract or retract webbing in accordance with the output of the flexible member sensor. The seat belt tension may thus be continuously maintained at a desired level.

Abstract: A seat belt retractor having a force limiter mechanism that can be stably operated when a pyrotechnic pretensioner is activated. As a pyrotechnic pretensioner is activated, a ring gear rotates in the counter-clockwise direction. Accordingly, an external tooth holding an end portion of a stopper is moved, whereby the end portion of the stopper becomes free. Therefore, the stopper expands because of its biasing force. Then, a release spring is released from the restriction of the stopper and thus pivots in the clockwise direction because of its biasing force. The release spring collides with a pin of the clutch pawl to press down the pin. Therefore, the clutch pawl is rotated about a clutch pawl pin in the clockwise direction, thereby canceling the mechanical connection between the motor and the spool.
