Abstract:
An anchor (1) is provided for securing at least one safety device to a structure (40, 70, 97), the anchor (1) including: a) a shaft (12) terminating in engagement means (11), such as an eyelet, the shaft (12) located in the structure (40, 70, 97) and adapted to reciprocate between a retracted position in the structure (40, 70, 97) and an extended position whereby the engagement means (11) is capable of extending beyond the external surface of the structure (40, 70, 97); b) stop means (31) adapted to limit the extent to which the engagement means (11) may be extended beyond the surface of the structure (40, 70, 97); and c) resiliently deformable means (14) such as a compressible rubber sleeve, adapted to coact with the shaft (12) and the stop means (31) to resist axial extension of the shaft (12) up to the extent determined by the stop means (31).
Abstract:
An improved strap for the construction of safety harnesses of the type designed to protect against falls provides increased flexibility and comfort. The strap is composed of a tubular sheath of elastic fabric that coaxially surrounds a typical high strength safety strap. The two components of the strap are sized so that the safety strap is longer than the surrounding tubular elastic sheath. This causes the longitudinal compression and thickening of the safety strap which then acts as filler to form a “pillow” from the sheath. This cushions the strap making it more comfortable while the longitudinal compression of the enclosed safety strap increases its flexibility. During a fall the sheath rapidly stretches and the enclosed safety strap elongates to full length to stop the fall in the normal manner of safety straps.
Abstract:
An anchorage assembly (100) is interconnected between a support structure (90) and a safety line (160, 161). The anchorage assembly (100) routes the safety line (160, 161) about a corner and accommodates passage of a slotted coupling device movably mounted on the safety line (160, 161).

Abstract:
An energy absorption device is disclosed for use both as in-line and horizontal life line shock or energy absorbers for fall arrest systems. The device includes a sleeve through which a bolt head is drawn. The bolt head compresses from the interior surface of the sleeve and thus absorbs energy as the device is stretched during a fall.
Abstract:
A personal safety device comprising a harness, a positioning strap attached to spaced apart region on the harness by way of a transfer strap. The ends of the positioning straps disconnect from the harness on the application of a force exceeding a predetermined limiting value.
Abstract:
A continuously woven web includes a first woven region interwoven with a plurality of yarns to define a first weave pattern and a second woven region forming a continuous weave with the first woven region and having a continuation of the yarns. The yarns are attached to the second woven region at a distal end thereof. The second woven region has a length defined by a length between a first end positioned adjacent a termination of the first weave pattern and the distal end. In the second woven region, the yarns have a greater elasticity in aggregate and a shorter length than the second woven region. Upon application of a tensile force to the webbing, the yarns in the second woven region may elongate to a length limited by the length of the second woven region.
Abstract:
A harness or belt to be worn by a person connected to some elevated anchor point, e.g., a rope grab on a safety line, to prevent the person from a fall. The device comprises at least one web or strap of a fabric which is subject to a shock load when the device has been used to arrest the fall of the person and plural shock load indicating strands or fibers located on the web or strap. The web or strap is a generally flat member having an exterior surface and is formed of plural interlaced strands of a first stretchable, yet strong material, e.g., nylon or polyester. The shock load indicating strands are of a contrasting color to the strands forming the strap or web and are visible from the exterior surface of the web. The shock load indicating strands are of a lesser stretchability than the strands of the web or strap. Accordingly, upon the shock loading of the harness or belt the shock load indicating strands rupture and fray out of the exterior surface of the web, whereupon the frayed ends are readily visible. This appearance indicates that the device has been used to arrest a fall and should be discarded or refurbished.
