2. The safety harness according to claim 1, wherein both leg harnesses comprise the recess.

3. The safety harness according to claim 1, wherein the pad consists of rubber foam.

4. The safety harness according to claim 1, wherein the pad consists of plastic.

5. The safety harness according to claim 1, wherein the pad consists of gel material.

6. The safety harness according to claim 1, wherein the recess is configured in such a manner to maintain a blood flow through a femoral vein of a suspended person.

7. The safety harness according to claim 1, wherein the pad comprises a material selected from the group consisting of a gel, rubber foam, and plastic.

8. The safety harness according to claim 1, wherein the recess is applied in an aerospace field.

9. The safety harness according to claim 1, wherein the recess is applied in a medical field.

10. The safety harness according to claim 1, wherein the recess is applied to one of a parachute harness, a climbing harness, a work harness, and a rescue harness.

11. The safety harness according to claim 1, wherein the pad has a thickness in an uncompressed state of greater than 30 millimeters.

12. The safety harness according to claim 1, wherein the recess is formed by a first pad and a second pad, wherein the first pad is separate from the second pad.

13. The safety harness according to claim 12, wherein the recess defines a gap of approximately 50 to 150 millimeters.

14. A safety harness for arresting a fall of a person and increasing the time that a person can safely remain suspended by the safety harness without suffering from orthostatic shock, the safety harness comprising: a first leg harness comprising an inner surface and an opposed outer surface and arranged such that the inner surface is capable of contacting a front portion of a first leg proximal to a crotch of a suspended person and again on an opposed side of a hip joint below a waist of a suspended person, wherein the inner surface includes a recess, wherein the first leg harness comprises opposing pads located along the first leg harness such that the opposing pads are proximal to a crotch of a suspended person when the first leg harness is in use, wherein a material thickness of the opposing pads is adapted to form the recess in such a manner that no compression occurs starting from that portion of the first leg harness that traverses a femoral vein of a suspended person in both directions along the first leg harness for at least 50 millimeters when the first leg harness is in use, wherein the opposing pads are made from different compressible materials.

15. The safety harness of claim 14, further comprising: a second leg harness comprising an inner surface and an opposed outer surface and arranged such that the inner surface is capable of contacting a front portion of a second leg of a suspended person and again on an opposed side of a hip joint of a suspended person, wherein the inner surface includes a respective recess.

16. The safety harness of claim 14, wherein the opposing pads comprise a material selected from the group consisting of a gel, rubber foam, and plastic.

17. The safety harness of claim 14, wherein a material thickness of the opposing pads is different.

18. The safety harness of claim 17, wherein the opposing pads have a thickness in an uncompressed state of greater than 30 millimeters.

19. The safety harness of claim 14, wherein a material thickness of the opposing pads is the same.

20. The safety harness of claim 14, wherein the opposing pads form a gap of approximately 50 to 150 millimeters.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0013] FIG. 1 shows an exemplary embodiment of a leg harness according to the invention.

[0014] FIG. 2 illustrates a further exemplary embodiment of a safety harness according to the invention with leg harness and chest harness.

[0015] FIG. 3 illustrates a photo of an exemplary embodiment.

DETAILED DESCRIPTION

[0016] FIG. 1 shows a schematic illustration of an embodiment of a leg harness according to the invention. Particularly, FIG. 1 shows a schematic illustration of a human body with internal organs and the corresponding vein system, wherein the reference numerals 7, 8, 9, 22, 23, 24, 25, 26, 27, 28, 31, 32, 33, and 34 show different organs, veins and arteries. In this connection, the reference numeral 9 denotes the femoral vein. The safety harness for the human body, which safety harness is illustrated in FIG. 1 as hatched areas 1 and 2 comprises two leg harnesses for two human legs, wherein at least one of the leg harnesses has a recess (or an opening) which is located in such a manner that the femoral vein is at least partially kept free. In order to clarify this, the right leg is illustrated in FIG. 1 with a leg harness 1 of a conventional safety harness, whereas the left leg is provided with a leg harness (or leg strap) 2 according to than exemplary embodiment of the invention. In this context, it can be seen that the right leg harness (conventional construction) squeezes the femoral vein 9, whereas the left leg harness according to the invention does not squeeze the femoral vein.

[0017] FIG. 2 shows a schematic illustration of a further exemplary embodiment of a safety harness according to the invention with leg harness (or leg strap, Beingurt) and chest harness (or chest strap, Brustgurt). The basic difference to the embodiments shown in FIG. 1 is that the safety harness additionally comprises a chest harness 3.

[0018] FIG. 3 illustrates a photo of a safety harness at which a recess can be seen at the right leg which recess is formed by two leg pads. A spacing between these two leg pads has the effect that the recess is formed between them which prevents a squeezing of the femoral vein or at least reduces the danger of squeezing.
