Abstract

A protective element is provided with a flat first material layer of a low-fold material and a flat second material layer of a folded cut-retardant material. A surface area of the second material layer in a stretched-out state is 1.2 to 2.5 times greater than a surface area of the first material layer in a stretched-out state. The second material layer is placed in a gathered state onto the first material layer. The first material layer forms a gliding layer for the second material layer.

First claim

What is claimed is:

1. A protective element comprising:
a flat first material layer comprised of a low-fold material and forming a supporting layer;
a flat second material layer comprised of a folded cut-retardant material;
wherein a surface area of the second material layer in a stretched-out state is 1.2 to 2.5 times greater than a surface area of the first material layer in a stretched-out state;
wherein the second material layer is placed in a gathered state onto the first material layer;
wherein the first material layer forms a gliding layer for the second material layer such that the folded cut-retardant material of the second material layer is moveable on the low-fold material of the first material layer and, by moving relative to the first material layer when engaged by cutting blades that are moving relative to each other, prevents that the first material layer arranged underneath the second material layer is gripped or pinched by the cutting blades.

2. The protective element according to claim 1 , wherein the surface area of the second material layer in the stretched-out state is 1.4 to 1.7 times greater than the surface area of the first material layer in the stretched-out state.

3. The protective element according to claim 1 , wherein the first material layer is connected with the second material layer at least at two fastening locations and wherein the fastening locations are spaced apart.

4. The protective element according to claim 1 , further comprising an outer layer wherein the outer layer is comprised of a cover material.

5. The protective element according to claim 4 , wherein the cover material is fixedly connected with the first material layer.

6. The protective element according to claim 5 , wherein the cover material is laminated, glued or sewn onto the first material layer.

7. The protective element according to claim 4 , wherein an edge of the cover material is fixedly connected to an edge of the first material layer.

8. The protective element according to claim 7 , wherein the cover material is laminated, glued or sewn onto the first material layer.

9. The protective element according to claim 1 , wherein at least one of the first and second material layers is made of a breathable material.

10. The protective element according to claim 1 , wherein at least one of the first and second material layers is comprised of a textile material.

11. An insert with a protective element of claim 1 .

12. Protective clothing comprised at least partially of a protective element of claim 1 .

13. The protective element according to claim 1 , wherein the folded cut-retardant material layer is comprised of a felt.

14. A protective element comprising:
a flat first material layer comprised of a low-fold material;
a flat second material layer comprised of a folded cut-retardant material;
wherein a surface area of the second material layer in a stretched-out state is 1.2 to 2.5 times greater than a surface area of the first material layer in a stretched-out state;
wherein the second material layer is placed in a gathered state onto the first material layer;
wherein the first material layer forms a gliding layer for the second material layer;
a device for holding the first material layer, wherein the device is shear-stiff.

15. The protective element according to claim 14 , wherein the device is comprised of a frame.

16. The protective element according to claim 15 , wherein the frame is comprised of a wire frame or a plastic frame.

17. The protective element according to claim 14 , wherein the device is comprised of a spacer material.

18. The protective element according to claim 17 , wherein the spacer material has a thickness of at least three millimeter.

19. The protective element according to claim 17 , wherein the spacer material is flexible.

20. The protective element according to claim 14 , wherein the first material layer is fixedly connected with the device.

21. The protective element according to claim 20 , wherein the first material layer is connected to the device by sewing, by laminating or by gluing.

22. A protective element as a cutting protection for a power tool comprising reciprocating blades that are moving reciprocatingly relative to each other, the protective element comprising:
a flat first material layer comprised of a low-fold material and forming a supporting layer;
a flat second material layer comprised of a folded cut-retardant material;
wherein a surface area of the second material layer in a stretched-out state is 1.2 to 2.5 times greater than a surface area of the first material layer in a stretched-out state;
wherein the second material layer is placed in a gathered state onto the first material layer;
an outer layer comprised of a cover material, wherein the second material layer is covered by the cover material of the outer layer and wherein the cover material is fixedly connected with the low-fold material of the first material layer;
wherein the first material layer comprised of the low-fold material forms a gliding layer for the second material layer comprised of the folded cut-retardant material such that, when reciprocating blades engage the protective element, the outer layer and the second material layer comprised of the folded cut-retardant material are engaged by the reciprocating blades and cutting into the first material layer is prevented by the second material layer gliding on the first material layer.
