Abstract

The invention relates to an air spring having a composite flexible member 4 in which cords 22 are embedded as a reinforcement. The cords 22 have cord angles to the peripheral direction of the flexible member 4 over the longitudinal length of the flexible member. The flexible member 4 comprises two flexible-member components (12a, 12b). The cord angle a in the first flexible-member component 12a is different from the cord angle .beta. in the second flexible-member component 12b. A method for making such an air spring is also disclosed.
