    Abstract: A fall protection system includes a mast assembly including a fixed mast section, a movable mast section, and a winch assembly. The fall protection system further includes a locking mechanism adapted to lock the movable mast section relative to the fixed mast section. The locking mechanism includes a locking pawl connected to the winch assembly. The locking pawl is adapted to rotate between an engaged position and a disengaged position. The locking pawl engages with the fixed mast section in the engaged position to prevent relative movement between the fixed mast section and the movable mast section. The locking mechanism also includes at least one spring adapted to bias the locking pawl towards the engaged position. Further, the winch assembly is adapted to retain the locking pawl in the disengaged position against the biasing of the at least one spring based on a tension selectively applied by the winch assembly.

    Abstract: A quick release buckle includes a housing defining a first opening therethrough and includes an engaging surface disposed adjacent to the first opening. A webbing is received through the first opening of the housing. A first pawl and a second pawl are pivotally mounted to the housing. A catch is at least partially received between the first pawl and the second pawl. A first pawl biasing member and a second pawl biasing member are engaged with the first pawl and the second pawl, respectively, and are configured to bias the first pawl and the second pawl into engagement with the catch. A bar is slidably received within the housing and extends across the first opening. A first bar biasing member and a second bar biasing member are configured to bias the bar toward the engaging surface, such that the webbing is gripped between the bar and the engaging surface.

    IPC: A62B35/00

    Abstract: A fall protection system includes a base assembly, a mast assembly, and a locking assembly adapted to lock the mast assembly with the base assembly. The locking assembly includes a first plate and a second plate. The locking assembly also includes a fixed member fixedly coupled to the second plate. The locking assembly further includes a locking pin including an elongate portion at least partially received within the fixed member and a first tab, the locking pin being movable relative to the fixed member between an engaged position and a disengaged position. In the engaged position, the first tab is at least partially received within a first groove such that the locking pin is engaged with the first plate. Further, in the disengaged position, the first tab is at least partially received within a second groove such that the locking pin is spaced apart from the first plate.

    CPC classification number: A62B35/0018 ,  A62B35/0025

    Abstract: A fall-protection safety harness is configured so that when the harness is worn by a user, a first ventral strap of the harness extends from the right shoulder of the user to the right hip of the user and a second ventral strap of the harness extends from the left shoulder of the user to the left hip of the user, wherein a first buckle portion is mounted on the first ventral strap and a second buckle portion is mounted on the second ventral strap. The first and second buckle portions are being detachably attached to each other to form a ventral buckle, wherein the first and second ventral straps and the first and second buckle portions are configured so that the ventral buckle is at least generally aligned with a sagittal plane of the user and harness. Each of the buckle portions comprise a vertically-elongated slot that is oriented within plus or minus 20 degrees of a vertical axis of the harness, wherein two layered portions of at least one of the ventral straps being in an overlapping relation pass through the vertical slot thereby forming a securing portion on the ventral strap, wherein the harness further comprises a strap securing means and wherein the strap securing means and the securing portion of the at least one ventral strap are configured and arranged such that the at least one buckle part is secured to the at least ventral strap.
