Abstract

An air spring includes a flexible member, which encloses an air volume, and two connecting parts. Each of the connecting parts has a clamp seat on which an end of the flexible member is attached with the aid of a clamp ring assigned to the clamp seat. The surface of at least one clamp seat is at least approximately convex and the total inner side of the clamp ring, which is assigned to the clamp seat, is configured to be at least approximately concave.
