Abstract: A seat belt retractor includes a base frame, a spool journalled to the base frame, a webbing wound around the spool, and a motor for rotating the spool. A speed-reduction mechanism is interposed between the motor and the spool. The speed-reduction mechanism includes at least one transmission train with a predetermined gear ratio, a common transmission element connected to the transmission train, and a resistant torque device connected to the transmission train. The common transmission element transmits rotation of the motor to the spool when the torque of the rotation is smaller than the preset value. Winding of the webbing is made based on the wearing condition of the webbing and the running condition of the vehicle.

Abstract: In a seatbelt retractor having a motor, a belt winding spool, and a switching mechanism that turns on and off a power transmission route between the motor and the spool, the switching mechanism includes a device that connects the power transmission route between the motor and the spool only when the motor rotates in the retracting direction. A ratchet mechanism allows the spool to rotate only in the retraction direction during the emergency operation, while allowing the spool in any directions in the normal operation. The resultant locking mechanism can be rapidly operated upon occurrence of an emergency, while the seatbelt retractor will not cause uncomfortable feeling or unpleasantness due to unnecessary locking when an occupant tries to withdraw the seatbelt.

Abstract: A winder for cord or line attachable to a power drill. The winder has a handle which rotatively supports a shaft having a threaded section. A pair of conical seat members are slidable on the threaded section to engage the core of a reel. A retainer such as a wing secures the seat members and reel in place. The user may hold the handle with one hand while operating the power tool to cause the reel to be rotated in a direction to take up the line. The conical seat members adapt the winder to use with reels of varying core diameter.

Abstract: A seat belt retractor has a belt reel that is rotatably mounted on a frame and on which a seat belt can be wound and unwound. A motive spring biases the belt reel in the winding direction.

The deformation of a deformable spring element brings the clutch into an engaged state. The spring element is held on one end of the spring by a holding device actuated by inertial force, at least for initiating its deformation.

Abstract: The Easy Arm Cable Winder Adapter is a labor and time saving device which allows small diameter cables to be retrieved and wound with an electric drill. The electric drill provides the torque required to retrieve and wind the cable. The Easy Arm Cable Winder Adapter can be modified to work with any brand or type of hand operated down hole instrumentation as well as to retrieve and spool any hand operated cable, wire, tube, line, filament, fiber, thread, string, twine, cord, rope or hose. More specifically, the Easy Arm Cable Winder Adapter significantly reduces the cost, time and effort required to retrieve Slope Indicator Company's Water Level Indicator (meter) cable and wind it back on its spool. Use of the Easy Arm Cable Winder Adapter on a water level meter makes sounding wells significantly faster and requires much less physical labor. The Easy Arm Cable Winder Adapter extends the range of applications for the water level meter and, in some cases, may preclude the use of more expensive technologies.

The means for rotating the spool may also be powered by an external current such as via an AC adapter.

Abstract: To reduce the cost of a seat belt retractor having a function of taking up a seat belt by power a motor. A spool is fitted in a base frame such that a torsion bar functions as a shaft of the spool. Two gear-clutch casings are disposed on the left and right sides of the spool via a pretensioner and a locking mechanism, respectively, wherein two motors are disposed to the gear-clutch casings, respectively. The two motors achieve respective functions which are different from each other and rotate at respective constant speeds. Unlike a case that one motor is used and the rotation speed of the motor is controlled, a speed controller and a noise filter for the motor are not required, thereby reducing the cost of the entire device.

Abstract: A reel which is driven by a motor is disposed in a casing. First and second restraining mechanisms for restraining movement of a cable are located at first and second openings formed in the casing for insertion of the cable. The cable extends between said first and second openings and is wound around the reel. One end of the cable is secured by the first restraining mechanism, and the motor is activated to rotate the reel, thereby winding the cable around the reel. When a pressure sensor located on the surface of the reel detects that the pressure between the cable and the reel reaches a given value, the motor is stopped. The other end of the cable is secured by the second restraining mechanism.

Abstract: A compact electric string winder that can be safely and conveniently deployed by masons and other construction workers. The string winder comprises a battery-driven electric motor inside a housing that fits in the palm of a hand and that attaches to a coaxial reel. The reel, or spool, has a receiving bore which receives and clamps upon by friction a rotating shaft pin extending from the motor. A wire spin guard prevents rotation of the reel when it is not in use. A switch lock, which locks the motor in its off position, is provided on a single track that intersects the on/off switch track at a right angle. The string winder is a compact device enabling easy and rapid deployment and retrieval of construction string, thereby enhancing worker efficiency, health and safety.
