The supporting body (2) consists of a relatively stiff first plastic and has a number o recesses (6), which pass through the supporting body (2) and are arranged in such a manner that the supporting body (2) is flexible in a longitudinal section provided with the recesses (6) and resists pressure forces. The skin (3) consists of a relatively supple second plastic and is placed on the supporting body (2) in such a manner as to close the recesses (6) in a tight manner and transfers pressure forces acting thereupon to the supporting body (2).
