What is claimed is: 1. A cylinder head cover used in connection with an internal combustion engine to tightly seal a contact surface of the internal combustion engine, the cylinder head cover comprising an elastomer part having one portion adapted to fit tightly against the contact surface of the internal combustion engine and at least one stiffening element embedded in the one portion of the elastomer part, the elastomer part also comprising an upstanding transition area connected to a plastic cover part, the transition area being formed entirely of elastomer and comprising at least one region of curvature so that the plastic cover part is horizontally offset from a part of the upstanding transition area. 2. The cylinder head cover according to claim 1, wherein the at least one region of curvature comprises two component areas, including one component area curved to one side of the elastomer part and another component area curved to an opposite side of the elastomer part. 3. The cylinder head cover according to claim 1, wherein the transition area extends in a direction perpendicular to the contact surface over a length of at least a few millimeters. 4. The cylinder head cover according to claim 1, wherein the length of the transition area is from 2 mm to 5 cm. 5. The cylinder head cover according to claim 1, wherein the region of curvature of the transition area possesses a radius of 2 mm to 20 mm. 6. A cover for tightly sealing a device comprising an elastomer first part possessing a portion adapted to fit tightly against a contact surface of the device and at least one stiffening element in the portion of the elastomer part, the elastomer first part comprising a transition area that is formed entirely of elastomer and transitions into a second part, the transition area at which the elastomer first part transitions to the second part being arc-shaped over at least a portion of its length. 7. The cover according to claim 6, wherein the transition area has at least two arc-shaped component areas which are different from one another. 8. The cover according to claim 7, wherein the two arc-shaped component areas are arranged so that they directly follow one another. 9. The cover according to claim 7, wherein one of the two component areas is curved to one side of the elastomer first part and the other component area is curved to an opposite side of the elastomer first part. 10. The cover according to claim 6, wherein the transition area extends in a direction perpendicular to the contact surface over a length of at least a few millimeters. 11. The cover according to claim 6, wherein the length of the transition area is from 2 mm to 5 cm. 12. The cover according to claim 6, wherein the radius of the arc-shaped portion is 2 mm to 20 mm. 13. The cover according to claim 6, wherein the second part is made of plastic. 14. The cover according to claim 6, wherein the second part is a cover part. 15. The cover according to claim 14, wherein the cover part is a cylinder head cover for an internal combustion engine.
