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.
