A winding drum for a line and/or for a line guide device which is adapted to receive and guide at least one line, wherein the drum is rotatable about the longitudinal axis thereof, wherein a first end region of the line and/or line guide device is or can be fixed to the drum and the line and/or line guide device can be wound on to and unwound from the drum by rotation of the winding drum in a winding-on and an unwinding direction about the drum longitudinal axis, wherein there is provided a drive device engaging the winding drum in order upon rotation of the drum in the unwinding direction thereof to exert a return force on the drum for rotation thereof in the winding-on direction. The drive device is in the form of a torsion spring which upon rotation of the drum in the unwinding direction is subjected to torsional stress and by virtue of the torsional stress exerts a torque on the drum for rotation thereof in the winding-on direction and the torsional stress exerts the return force on the drum.

Retractable relates to retractable leashes for walking and training dogs or other animals and comprises a housing containing a spring-loaded spool having a leash wound on it and a device for controlling the length of the leash, comprising at least one means for locking the movement of the spool, wherein the device for controlling the length of the leash comprises a device for determining the movement of the spool, an electronic device linked thereto for controlling the means for locking the movement of the spool, a device for activating and deactivating the electronic device for controlling the means for locking the movement of the spool, at least one actuator of the means for locking the movement of the spool comprising a fixing device, the actuator being connected to the device for controlling the means for locking the movement of the spool, and at least one power supply.

Provided is a cable take-up device for a flexible flat cable routed for a slide seat slidably supported so as to be movable forward and backward along a fixed rail fixed to the vehicle cabin floor. The cable take-up device includes: a take-up housing part that takes up a housed portion in a drawable manner and houses it inside with a front end portion fixed to a rail front end portion and a rear end portion fixed to the slide seat; a take-up force generation part that generates a take-up force in a direction of take-up of the housed portion through drawing of the cable routing body; and a slit that applies the take-up force of the take-up force generation part to the housed portion.

Provided herein is a lanyard attachment for storing a lanyard. The lanyard attachment has a housing, means for releasably storing a lanyard in the housing, for example a rotatable spool, a guide at the proximal end of the housing to guide the lanyard into the housing and a holder at the distal end from which an object is suspended. Also provided is a retractable lanyard in which a cord or lanyard is stored in a coiled configuration within the housing and a system for releasably storing a lanyard in the lanyard attachment.

The utility model patent discloses an electric vehicle charger with a retractable wire. The electric vehicle charger includes a storage box, a winding wheel and a wire; one end of the wire is connected with the charger; the winding wheel is mounted in the storage box; a coil spring and a sliding ring are provided in the winding wheel; and the sliding ring has a conducting ring and a conducting strip. When the winding wheel is rotated, the conducting strip rotate synchronously with the winding wheel; and furthermore, when the conducting strip slides on an outer surface of the conducting ring, the conducting strip and the conducting ring are kept in electric contact. The electric vehicle charger further includes a pull-stop structure; the pull-stop structure includes a limiting gear and a latch; the latch selectively limits the limiting gear; and the limiting gear is an incomplete gear.

A cord management apparatus includes a housing, a reel rotatably disposed within the housing, and a button operably coupled to the reel and configured to control extension and retraction of a window blind cord attached to the reel, according to various embodiments. The housing may include a back portion and a front portion. The front portion may be at least one of detachably and pivotally coupled to the back portion such that the housing is openable to allow a user to have access to an internal chamber defined by the housing.

A swivel connector for a retractable assembly comprises a body defining a hollow portion, an indicator block received within the hollow portion of the body and sized to be movable within the body, a support upon which the indicator block rests, the support being movable relative to the body, and a yoke to which a lifeline can be connected, the yoke being connected to the support. The yoke and support move relative to the hollow portion of the body in unison, such that movement of the yoke and body relative to each other will cause the indicator block to move relative to the body between a first position and a second position, and wherein the indicator block is visible when in at least one of said first and second positions, to indicate that the retractable has been subject to a fall.

A tool, such as a tape measure, including a spring-based retraction system is shown. The retraction system utilizes an epicyclic gear train coupled between the tape blade winding reel and a rotating arbor or axle within the tape measure. A spiral spring has an outer end coupled to the reel and an inner end coupled to the axle. The gear train may be a reduction gear train such that the axle rotates slower than the reel. By coupling the spiral spring between the gear train input and gear train output, high energy density springs may be used, which may allow for decrease in housing size, increase in tape length or thickness for a given housing size, and/or advantageous retraction speed control.

A seat assembly within an internal cabin of a vehicle includes an electrical interface housing that contains a first portion of a cable that is configured to provide one or both of electrical power or electrical signals to one or more electrical components. A cable reel rotatably coupled to a body of the electrical interface housing. The cable reel is configured to rotate about an axis. The first portion of the cable includes an adjustable coil that is coiled around the cable reel. The cable reel is rotatable in a first direction to deploy the first portion of the cable outwardly from the electrical interface housing and a second direction to retract the first portion of the cable inwardly into the electrical interface housing.
