Safety harness with pseudo-crossover ventral straps having two folds
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. A first buckle portion is mounted on the first ventral strap and a second buckle portion is mounted on the second ventral step. The at least one of the ventral straps comprises at least two fold portions formed by an upper portion of the ventral strap folded at least partially onto itself and by a lower portion of the ventral strap folded at least partially onto itself, wherein the at least one strap performs a 180 degrees twist at the vertically-elongated slot of the buckle portion mounted to the ventral strap thereby forming a securing portion on the ventral strap which is located between the two fold portions and wherein the at least one buckle portion is secured to the at least one strap at the securing portion of the strap.

wherein at least one of the ventral straps comprises at least two fold portions formed by an upper portion of the ventral strap folded at least partially onto itself and by a lower portion of the ventral strap folded at least partially onto itself,
wherein the at least one strap performs a 180 degrees twist at the vertically-elongated slot of the buckle portion mounted to the ventral strap thereby forming a securing portion on the ventral strap which is located between the two fold portions and
wherein the at least one buckle portion is secured to the at least one strap at the securing portion of the strap.
2 . The fall-protection safety harness according to claim 1 , wherein the 180 degrees twist provides a loop on the ventral strap.
3 . The fall protection safety harness according to claim 1 , wherein the upper and lower portions of the ventral strap are folded such that a transverse strap portion is formed in which two layered portions of the ventral strap are in a substantially congruent overlap relation.
4 . The fall protection safety harness according to claim 3 , wherein the transverse strap portion faces away from a ventral strap towards the buckle part to which the ventral strap is attached to.
5 . The fall protection safety harness according to claim 3 wherein the transverse strap portion provides for an excess length of the ventral strap, wherein the transverse strap portion is oriented substantially perpendicular to the long axis of the ventral strap and to the sagittal plane of the user.
6 . The fall protection safety harness according to claim 3 , wherein the longitudinal axes of the folded portion and of the transverse strap portions are angled to each other, wherein the longitudinal axes enclose an angle of between substantially 0 degrees to substantially 90 degrees.
7 . The fall protection safety harness according to claim 2 , further comprising a strap securing means, wherein the loop is arranged around the strap securing means.
8 . The fall-protection safety harness according to claim 1 , wherein the generally vertically-elongated slot is a substantially vertically-elongated slot that is oriented within plus or minus 10 degrees of a vertical axis of the harness; and wherein the buckle portion that comprises the substantially vertically-elongated slot also comprises at least one auxiliary elongate slot that exhibits a long axis that is oriented at an angle of from 15 degrees to substantially 90 degrees relative to the substantially vertically-elongated slot.
9 . The fall-protection safety harness according to claim 8 , wherein the vertically-elongated slot and/or the at least one auxiliary slot are integrally formed with the buckle part.
10 . The fall-protection safety harness according to claim 8 , further comprising a strap routing mechanism in which the vertically-elongated slot and at least one auxiliary slot are arranged, wherein the buckle part comprises a vertically-elongated slot, wherein the vertically-elongated slots of the strap routing mechanism and of the buckle part are in an overlap relation such that the ventral strap passes through the vertically-elongated slots of the buckle part and of the strap routing mechanism.
11 . The fall-protection safety harness according to claim 1 , further comprising a connection strap fixedly connected to the upper and the lower portion of the ventral strap such that a load acing upon the upper strap is also transmitted to the lower strap and such that a load acting upon the lower strap is also transmitted to the upper strap.
12 . The fall-protection safety harness according to claim 11 , wherein the connection strap is stitched to the upper and/or lower portion of the ventral strap.
13 . The fall-protection safety harness according to claim 8 , wherein the fall protection safety harness comprises a connection strap and wherein the connection strap passes through the at least one auxiliary slot.
14 . The fall-protection safety harness according to claim 3 , wherein the two portions of the transverse strap portion are fixedly connected to each other, by stitching.
15 . The fall-protection safety harness according to claim 1 , wherein each of the ventral straps comprises at least two fold portions each formed by an upper portion of the ventral strap folded at least partially onto itself and by a lower portion of the ventral strap folded at least partially onto itself,
wherein each of the straps performs a 180 degrees twist at the vertically-elongated slot of the buckle portion mounted to the ventral strap thereby forming a securing portion on the ventral strap which is located between the two fold portions,
wherein each of the buckle portions is secured to the at least one strap at the securing portion of the strap.
16 . The fall-protection safety harness according to claim 7 , wherein a strap securing means is arranged at both ventral straps and buckle parts, respectively.
17 . The fall-protection safety harness according to claim 10 wherein a strap routing mechanism is arranged at both ventral straps.
18 . The fall-protection safety harness according to claim 1 , wherein the first and second buckle portions are directly attached to each other by way of metal components of the first and second buckle portions and wherein the first and second buckle portions are not directly attached or connected to each other by way of any flexible strap or webbing.
19 . The fall-protection safety harness according to claim 1 , wherein the first buckle portion comprises a base plate and a cover plate that are permanently attached to each other by multiple mechanical fasteners, and wherein the base plate and the cover plate of the first buckle portion are configured to define a receiving cavity into which a catch of the second buckle portion can be received in order to attach the first and second buckle portions to each other, and wherein the base plate and the cover plate also define an opening into which the catch of the first buckle portion can be inserted to reach the receiving cavity.
20 . A method of donning the fall-protection safety harness of claim 1 , the method comprising wrapping an upper portion of the safety harness about the shoulders and upper torso of the user in the manner of a jacket and then attaching the first and second buckle portions to each other to form the ventral buckle, wherein the method does not require any step of pulling the harness downward over the head and shoulders of the user in the manner of a pullover sweater.
