The sealing arrangement according to claim 6, wherein the stiffening elements are coated with an adhesive for adhesion with respect to the elastomer part. 10. The sealing arrangement according to claim 6, wherein the stiffening elements together form a rectangular frame. 11. The sealing arrangement according to claim 10, wherein each of the stiffening elements is positioned along one side of the frame, and the stiffening elements overlap one another at corner areas of the frame. 12. The sealing arrangement according to claim 6, wherein the stiffening elements have a U-shaped cross section. 13. The sealing arrangement according to claim 6, wherein the elastomer part located between the stiffening elements has a thickness of less than or equal to 1 mm. 14. The sealing arrangement according to claim 6, wherein the sealing arrangement is connected to a plastic cover. 15. The sealing arrangement according to claim 6, wherein the sealing arrangement is a part of a cylinder head cover of an internal combustion engine. 16. A process for producing a sealing arrangement, comprising: arranging at least two stiffening elements in a tool so that only end portions of adjacently positioned stiffening elements overlap one another in an overlapping area and so that the at least two stiffening elements together are arranged in a shape of a frame surrounding a central opening; and injecting elastomer material into the tool so that at least some of the elastomer material is between the end portions of each of the adjacently positioned stiffening elements to securely connect the two stiffening elements to one another in the shape of the frame. 17. The process according to claim 16, wherein the stiffening elements are coated with an adhesive before the stiffening elements are arranged in the tool. 18. The process according to claim 16, wherein the adhesive is applied to the stiffening elements with a bath coating process. 19. A cylinder head cover adjoining a contact surface of an internal combustion engine and attached to the contact surface by a plurality of fasteners, the cylinder head cover comprising a frame-shaped elastomer body, a plurality of stiffening elements embedded in the elastomer body, and a plurality of holes passing through the elastomer body and the stiffening elements, with the fasteners being positioned in the holes, only end portions of adjacent ones of the stiffening elements overlapping one another in an overlapping area, with elastomer forming the elastomer body being located in the overlapping area between the overlapping end portions of the adjacent stiffening elements to securely connect together the adjacent stiffening elements by the elastomer, the plurality of stiffening elements being arranged in a shape of a frame.
