Abstract: A webbing take-up device includes a second clutch that transmits rotation of a motor to a spool. The second clutch includes a base including a first spring catch portion, a clutch gear, a clutch spring including a coil portion, having an end portion at one side caught to the first spring catch portion, and a lever that includes a second spring catch portion catching an end portion at another side of the clutch spring, and that enlarges diameter of the coil portion to abut the clutch gear by moving the end portion at the another side of the clutch spring toward one side in the circumferential direction of the base. A terminal end of the end portion at the one side of the clutch spring abuts the first spring catch portion when the lever is rotated toward the one side in the circumferential direction of the base.

Abstract: A webbing take-up device includes a spool that takes up webbing worn by an occupant, an input gear that is rotated by rotation force being transmitted, a spool gear that rotates the spool by being rotated, and a second clutch that is provided between the input gear and the spool gear, and that transmits rotation force of the input gear to the spool gear by being rotated by the input gear. The webbing take-up device further includes a sub clutch spring that is provided between the input gear and the second clutch, that transmits rotation force of the input gear to the second clutch when the input gear is rotated toward one side, and that shuts off transmission of rotation force of the input gear to the second clutch when the input gear is rotated toward another side.

Abstract: Disclosed is an improved reel assembly for use in conjunction with an occupant restraint system. The assembly employs a dual locking arrangement whereby an occupant can be restrained during both major and minor incidents. After a minor incident, the reel assembly can be conveniently unlocked, without the need for accessing the push button, by applying counter tension to the webbing. After a major incident, the reel assembly remains locked until the occupant disengages the reel via a push button. When the reel assembly experiences the force of a major incident, rotation of the webbing shaft may be first partially arrested by the engagement of a first of two locking teeth on a locking dog with a first of two engagement surfaces on a geared end plate and subsequently completely arrested by the combined engagements of the first and second locking teeth with their respective first and second engagement surfaces.

Abstract: The invention is a centrifugal brake device that is a speed control means for spring motor hose and cable reels. This brake device is mounted to a shaft of a hub associated with the reel, such that the device controls the reel rotation speed.

Abstract: A retractor mechanism for a pet collar. The mechanism includes a case with a cavity, a spool assembly with a spool plate, a line wound on the spool assembly with a free end exiting the case that is attached to a leash handle, a power spring that biases the spool assembly to a wound state, and a centrifugal/inertial brake having with a lock member with a heavier distal end a lighter proximal end, and lock member spring. The lock member pivots on the spool plate. When the spool assembly is spun above a threshold rotations speed, a centripetal force acting on the distal end of the lock member exceeds a spring force of the lock member spring acting on the proximal end of the lock member, thereby pivoting the lock member into contact with a catch in the cavity of the case to prevent the spool assembly from rotating further.

Abstract: A spring retractable reel having a pneumatic retraction governor or air motor for regulating the rewind speed of a spool for taking up a line of material. For example, an air motor includes a rotor having vanes, a first port opening onto one side of the rotor, and a second port opening onto a second side of the rotor. A valve adjustably restricts a continuous flow of ambient air through the second port, and the valve defines an opening sized smaller than the first port. The rotation of the spool and the rotor are fixedly coupled together, for example, with a chain. When the spool rewinds the line of material, the rotor rotates, which in turn draws ambient air through the first port, a portion of which ambient air is restricted from exiting the second port due to the valve thereby compressing air within the air motor to regulate or limit the speed at which the spool rewinds the line of material.

Abstract: A cable reel makes possible a diversion of a braking pulse onto a housing by using elastic elements that mount the cable reel inside the housing, whereby the braking energy is converted into heat. The cable reel is, in particular, also suited for reel bodies that hold long cable lengths. In particular, the cable reel is used in a vacuum cleaner.

Abstract: A deceleration device of a tape rule is equipped with a speed reduction gear wheel in the tape rule housing. The speed reduction gear wheel is in mesh with a transmission gear wheel of a reel for coiling a measuring tape such that the rotational speed of the reel when retrieving the extended tape is retarded thereby preventing the danger of scratching the user's finger or damaging the tape itself by abrasion or impingement. Engagement of the speed reduction gear wheel and the transmission gear wheel can be released by operating a flat pusher plate provided on the housing.

Abstract: A restraining assembly for use in conjunction with a linear transducer. The restraining assembly comprises a plurality of spaced apart magnets positioned on a stationary frame, where the magnets provide a reverse torque and restrict excessive rotational speed on a spool when a copper disc or equivalent magnetic flux medium is rotated at a close proximity to the face of the magnets. When a cable is suddenly released and allowed to freely return on the rotating spool, the restraining assembly restrains the high rotational speed at which the cable can accelerate when returning or retracting to the spool, such that the restraining assembly prevents the cable from self-destruction and/or damage to the linear transducer.
