Abstract

A tensioner for an accessory drive of an internal combustion engine equipped with a starter-generator (1), the tensioner (6; 78) comprising a support (5) designed to be fastened on the starter-generator (1), a body (15) carried by said support (5) and rotatable about a first axis (A) and two pulleys (23, 24) carried by said body (15) and rotatable with respect thereto about respective axes parallel to the first axis (A); the tensioner (6; 78) comprises a damping device (60) interposed between the body (15) and the support (5), the damping device (60) comprises a damper (62) defining a damping dependent on a relative rotation angle between the body (15) and the support (5).
