Abstract

The invention relates to pads ( 200 ), in particular for orthopedic aids, comprising a pad pressure element ( 100, 101 ). The invention also relates to the use of the pads according to the invention in orthoses or bandages as well as to orthoses or bandages comprising pads according to the invention.

First claim

The invention claimed is:

1. A pad for orthopedic aids, comprising a pad base body made of a first material and at least one pad pressure element made of a second material, the pad pressure element being at least partially embedded in the pad base body, and the first material of the pad base body being softer than the second material of the pad pressure element, the pad pressure element comprising at least two pin-shaped elevations and a base element, the pin-shaped elevations being arranged on the base element, the pin-shaped elevations being movable in a viscoelastic manner by way of the base element, the base element including at least one hole, and the at least two pin-shaped elevations on the base element being positioned at an edge of the at least one hole, characterized in that the at least two pin-shaped elevations are connected to one another by way of a web spanning the hole, and at least one further pin-shaped elevation being located on the web.

2. The pad according to claim 1 , characterized in that at least a portion of the at least two pin-shaped elevations is embedded in the pad base body.

3. The pad according to claim 1 , characterized in that the base element of the pad pressure element is web-shaped or plate-shaped.

4. The pad according to claim 1 , characterized in that the pad comprises at least two flexible pad pressure elements, the two pad pressure elements being connected to one another by way of a connecting element.

5. The pad according to claim 1 , characterized in that the at least two pin-shaped elevations protrude at least 2 mm into the pad base body.

6. The pad according to claim 1 , characterized in that at least two pairs of pin-shaped elevations are positioned at the edge of the hole and are in each case connected to one another by way of a web spanning the hole, the webs of the two pairs of pin-shaped elevations intersecting, approximately in the center of the hole.

7. The pad according to claim 6 , characterized in that a further pin-shaped elevation is arranged on and/or-next to the intersecting point of the twe webs.

8. The pad according to claim 1 , characterized in that the base element and the pin-shaped elevations are designed in one piece, and in particular made of the same material.

9. The pad according to claim 1 , characterized in that the pad base body includes a first base surface facing a user and a second base surface facing away from the user, the pin-shaped elevations projecting from the base element positioned in the second base surface facing away from the user in the direction of the first base surface facing the user.

10. The pad according to claim 1 , characterized in that the material of the pad base body has a Shore hardness of at least 10 Shore OO and at most 50 Shore OO and the material of the pad pressure element has a Shore hardness of at least 10 Shore A and at most 80 Shore A.

11. The pad according to claim 1 , characterized in that a distance between adjacent pin-shaped elevations is at least 2.5 times and at most 6 times as wide as a height of the pin-shaped elevations.

12. The pad according to claim 1 , characterized in that the pad is a knee pad, an ankle pad, a back pad, an elbow pad, a pad for the arm region or a pad for the abdominal region.

13. The pad according to claim 1 , characterized in that the pad is a knee pad and comprises at least two pad elements, the two pad elements of the pad being positioned in the pad base body so that they are located in a region of the user's infrapatellar fat pads when the pad is applied and can exert pressure thereon.

14. An orthosis or a bandage comprising a pad according to claim 1 .

15. The pad according to claim 6 , characterized in that a further pin-shaped elevation is arranged on or next to the intersecting point of the webs.

16. The pad according to claim 1 , characterized in that the material of the pad base body has a Shore hardness of at least 10 Shore OO and at most 50 Shore OO or the material of the pad pressure element has a Shore hardness of at least 10 Shore A and at most 80 Shore A.
