20090211847 | ENERGY ABSORBING LIFELINE SYSTEMS - A lifeline system includes a lifeline and a hub around which the lifeline is coiled. The hub deforms to absorb energy at a predetermined level of force exerted thereon by the lifeline. For example, the hub can be deformable to absorb energy so that a peak fall arrest force in a drop test of the lifeline system with a 220 pound mass attached to the lifeline over a distance of up to 6.56 feet is not more than 1900 pounds. In several embodiments, the peak fall arrest force is no more than 1500 pounds or no more than 1349 pounds. | 08-27-2009 |
20090211848 | SELF-RETRACTING LIFELINE SYSTEMS AND BRAKING SYSTEMS THEREFOR - A lifeline system includes a lifeline and a drum assembly around which the lifeline is coiled. The drum assembly is rotatable about a first axis in a first direction during extension of the lifeline and in a second direction, opposite of the first direction, during retraction of the lifeline. The lifeline system further includes a tensioning mechanism in operative connection with the drum assembly to impart a biasing force on the drum assembly to bias the drum assembly to rotate about the first axis in the second direction. The lifeline system further comprises a braking mechanism in operative connection with the drum assembly. The braking mechanism includes a catch that is rotatable relative to the drum assembly about a second axis that is not concentric with the first axis. The second axis is operatively connected to the first axis so that the second axis rotates about the first axis in the same direction as the drum assembly when the drum assembly is rotating about the first axis. A center of mass of the catch is located in the vicinity of the second axis. The catch rotates about the second axis in the second direction when the drum assembly is rotated in the first direction at at least a determined angular acceleration to cause an abutment section of the catch to abut an abutment member of the lifeline system (for example, by moving radially outward a sufficient amount) and stop the rotation of the drum assembly. | 08-27-2009 |
20090211849 | SYSTEMS FOR USE WITH MULTIPLE SAFETY DEVICES AND CONNECTORS FOR USE THEREWITH - A system includes a support including an extending rigid member and a first attachment at a first position on the rigid member to which a first self-retracting lifeline is attached. The first self-retracing lifeline includes a first housing from which a first lifeline exits. The first housing is movable relative to the rigid member. The system also includes at least a second attachment at a second position on the rigid member to which a second self-retracing lifeline. The second self-retracting lifeline includes a second housing from which a second lifeline exits. The second housing is movable relative to the rigid member independent of the movement of the first housing. The first position is spaced from the second position. The system further includes a connector attached to the frame to connect the frame to an article (for example, a safety harness such as a full body safety harness) worn by a user. | 08-27-2009 |
20120205478 | RETRACTING LIFELINE SYSTEMS FOR USE IN TIE-BACK ANCHORING - A retracting lifeline system, includes: a housing, a first connector attached to the housing, a lifeline, and a hub to which the lifeline is attached at a first end of the lifeline and around which the lifeline is coiled within the housing. The housing includes an opening through which the lifeline exits the housing. The hub is tensioned to rotate in a first direction to cause retracting of the lifeline and coiling of the lifeline around the hub. The retracting lifeline system further includes a second connector attached to a second end of the lifeline. At least a section of the lifeline has an initial ultimate tensile load of at least 8000 pounds and is abrasion resistant (that is, satisfying the abrasion test requirement set forth in the ANSI/ASSE Z359.13-2009 standard) such that the section of the lifeline is available for tie-back anchoring using the second connector. The section of the lifeline is at least partially retractable within the housing. | 08-16-2012 |
20120228056 | SAFETY HARNESSES, CONNECTIVE RING ATTACHMENTS FOR USE IN SAFETY HARNESSES AND BACK PADS FOR USE IN SAFETY HARNESSES - A back pad system for use in connection with a safety harness which includes at least two spaced back straps and a connector adapted to be connected to a line or lanyard. In one form, the system includes a back pad having passages through which the two back straps can be passed to be crossed over the connector, an attachment to which the connector can be moveably attached, and at least one member that captures the connector in an upright position upon application of force such as manual force (either directly or indirectly) to the connector to move the connector to the upright position. | 09-13-2012 |
20130025968 | Systems for Use with Multiple Safety Devices and Connectors for Use Therewith - A system includes a support including an extending rigid member and a first attachment at a first position on the rigid member to which a first self-retracting lifeline is attached, The first self-retracting lifeline includes a first housing from which a first lifeline exits. The first housing is movable relative to the rigid member. The system also includes at least a second attachment at a second position on the rigid member to which a second self-retracting lifeline. The second self-retracting lifeline includes a second housing from which a second lifeline exits, The second housing is movable relative to the rigid member independent of the movement of the first housing. The first position is spaced from the second position. The system further includes a connector attached to the frame to connect the frame to an article worn by a user. | 01-31-2013 |
20140060969 | Fall Protection Safety Harness - Apparatus and associated methods relate to a fall-protection safety harness having padding structures located at harness pressure points, including dorsal and shoulder regions, the lumbar region, and leg regions. The padding structures may be constructed to provide air-flow parallel to a wearer's skin. Air may flow through wearer-webbing channels created by displacing a webbing via comfort pads. For example, the padding structures may be made by sandwiching foam pads between mesh fabric materials. The foam pads may be captured by the two mesh fabrics using circumferential stitching, for example. Circumferential stitching may permit the foam to retain its uncompressed form which may facilitate webbing displacement. Separate and symmetric pads may be located on both sides of a wearer's spine, both at the lumbar region and at the dorsal region of the back, permitting airflow between pads and along the wearer's spine. | 03-06-2014 |
