Abstract

A fitting (10) for a vehicle seat, in particular for a motor vehicle seat, includes a first fitting part (11), on which a ring gear (17) is formed, a second fitting part (12), on which a gear (16) is formed, which gear meshes with the ring gear (17), whereby the two fitting parts (11, 12) are in a transmission connection with each other, and a rotating eccentric (27, 35) for driving a relative rolling motion of the gear (16) and the ring gear (17). The eccentric is driven by a carrier (21), wherein the eccentric (27, 35) is rotatably supported in a collar (38), which is associated with one of the two fitting parts (11, 12), or in a bushing (28) sitting in said collar (38) in a rotationally fixed manner. A blocking element (50) for the eccentric (27, 35) is operative at least at times between the eccentric (27, 35) and the bushing (28). The bushing (28) has teeth (28a) pointing radially outward and the blocking element (50), which surrounds the bushing (28) annularly, has at least one, in particular two, tooth segments (58) pointing radially inward for interacting with the teeth (28a).
