Claim 13

A sealing strip means according to claim 10, characterized in that the depressions have a cone-like shape.

Claim 14

A sealing strip according to claim 10, characterized in that the depressions have a pyramid-like shape.

Claim 15

A sealing strip according to claim 10, characterized in that the depressions are about three-tenths of a millimeter in depth.

Claim 16

A sealing strip according to claim 13, characterized in that the largest diameter of a depression in the surface of the sealing lip means amounts to about six-tenths of a millimeter.

Claim 17

A sealing strip made from an elastomeric material for use in doors or the like of motor vehicles where the sealing strip abuttingly engages a vehicle metal part; said sealing strip comprising: sealing lip means having an abutment side for engagement with the metal part and a base section for fixedly attaching the sealing strip to another vehicle part arranged adjacent the metal part, said abutment side including a plurality of closely spaced serially arranged recesses separated by thin abutment lines formed by the edges of said recesses, said recesses being so arranged on said abutment side that the only contact between the sealing lip means and the metal part is along said thin abutment lines whereby noises due to relative movement of the metal part and the sealing strip are minimized, and characterized in that respective abutment lines surround each of said recesses to form an equilateral polygon.

Claim 18

A sealing strip made from an elastomeric material for use in doors or the like of motor vehicles where the sealing strip abuttingly engages a vehicle metal part; said sealing strip comprising: sealing lip means having an abutment side for engagement with the metal part and a base section for fixedly attaching the sealing strip to another vehicle part arranged adjacent the metal part, said abutment side including a plurality of closely spaced serially arranged recesses separated by thin abutment lines formed by the edges of said recesses, said recesses being so arranged on said abutment side that the only contact between the sealing lip means and the metal part is along said thin abutment lines whereby noises due to relative movement of the metal part and the sealing strip are minimized, and characterized in that respective abutment lines surround each of said recesses to form an equilateral polygon.

Claim 19

A sealing strip according to claim 15, characterized in that said sealing lip means is of a curved C-shaped configuration in an unstretched condition, the bottom part of the C being formed by the base section, and in that said abutment side is on the outwardly facing surface of the sealing lip means.

Claim 20
