A line retraction device includes a rotatable drum having a line associated therewith, with the line including a first end directly or indirectly attached to the drum and a second end opposite the first end, and at least one retraction member biasing the drum in a first rotational direction of the drum opposite a second rotational direction of the drum, where the drum is configured to: (i) retract the line when the drum moves in the first rotational direction; and (ii) payout the line when the drum moves in the second rotational direction. The device further including a damper assembly configured to provide rotational resistance to the drum in: (i) the first rotational direction of the drum as the line is being retracted; and (ii) the second rotational direction as the line is being paid out.

A buffer type speed difference falling protector includes a shell, a speed difference falling protector body and a speed difference falling protector body, wherein the shell is provided with an opening; the frame body is arranged in the shell; the winding device is arranged on the frame body, can wind the rope body when the winding device rotates in the forward direction, and releases the rope body when the winding device rotates in the reverse direction; and the elastic resetting piece is used for driving the winding device to rotate in the positive direction. The plurality of pawls are arranged on the fixing piece, when the braking device rotates, the plurality of pawls are thrown out synchronously to be contacted with the ratchets, the braking speed is high, the braking reliability is high, and the plurality of pawls can equally divide the impact force during braking.

A self-retracting lanyard including a main body and a retractable line. The retractable line is coupled to the main body so as to be extendible and retractable relative to the main body and to be restricted from extending relative to the main body in response to a user of the self-retracting lanyard falling. The self-retracting lanyard further includes a manual control operable by the user to initiate controlled descent of the retractable line relative to the main body.

A housing for a self-retracting lifeline includes an outer area disposed on a portion of a first side of the housing, the outer area being planar, a label area stepped down from the outer area, an outer perimeter of the label area corresponding to an inner perimeter of the outer area, and a number of protruding members disposed at least on a portion of the first side of the housing and being stepped up from the outer area.

A self-retracting lanyard including a main body and a retractable line. The retractable line is coupled to the main body so as to be extendible and retractable relative to the main body and to be restricted from extending relative to the main body in response to a user of the self-retracting lanyard falling. The self-retracting lanyard further includes a manual control operable by the user to initiate controlled descent of the retractable line relative to the main body. The manual control may be operable by the user to deliver a fluid (e.g. compressed gas) from a fluid supply disposed in a housing of the manual control to an actuator of the main body to initiate controlled descent. Solar panel(s) may be disposed on the main body. When the retractable line is retracted, the housing may dock with and be charged by a solar powered charger disposed on the main body.

A fall-protection apparatus with a drum and a rotationally-activated braking device including at least one velocity-actuated pawl that is mounted on a pawl-support plate that is rotatable relative to the drum through a predetermined range between a first position and a second position. The pawl-support plate is rotatable relative to the drum from the first position to the second position upon the pawl-support plate experiencing a rotational acceleration that is above a predetermined threshold value of rotational acceleration. When the pawl-support plate is in the second position, the velocity-actuated pawl can be actuated by a rotational velocity that is lower than a rotational velocity required to actuate the pawl when the pawl-support plate is in the first position.

A fall-protection apparatus comprising a rotationally-activated braking device that comprises at least one flexure-borne pawl.

A fall arrester includes a holder, rotating drum, braking device, and dust cover. The rotating drum is pivotally provided on and within the holder, and includes a main body and at least one pawl; the main body has an accommodating part to be wound by a cable and a setting part. The pawl is pivotally provided on the setting part, and the braking device is fixed to the holder and between the holder and the setting part. When the rotating drum rotates quickly by pull of the cable, the pawl would pivot and make a part thereof abut against a part of the braking device to stop the rotating drum. The dust cover is fixed to the setting part, and thereby prevents dust from affecting the pawl and the braking device located therein, and thus to enhance safe use thereof.

A fall arrester includes holder, rotating drum, and braking module. The rotating drum is pivotally installed on the holder, and includes main body and pawl which has first abutting portion and is pivotally provided on setting part. The braking module is fixed to holder, and includes cover, friction plate, and ratchet plate, being coaxially set in order. The ratchet plate has second abutting portion on its periphery. When rotating drum rotates at speed greater than or equal to predetermined rotating speed, and first abutting portion moves to second position to abut against second abutting portion, the cover and ratchet plate rotate relative to friction plate, driven by rotating drum. Additionally, the cover and ratchet plate generate frictional resistance with friction plate respectively to stop the rotating drum. Thus, the braking module of the fall arrester can be replaced thereby enabling provision of a new braking module as an initial condition.

A cold-weather garment for providing additional safety for those working on climbing of structures is presented. A safety harness to be combined with a cold-weather garment to provide for further safety and comfort of those who have a need for climbing structures. Furthermore, the safety harness shall further need to be coupled to a structure to promote further safety as well as be cost efficient and comfortable.
