摘要

Seat assembly for a bicycle, especially a seat assembly supporting the back of the user, comprises a seat frame, a backrest, and a seat element (4). The seat element has an upper-lying seat surface with a recess (44) for the buttocks. The recess has a width that gradually reduces along the longitudinal axis (T) from the rear edge (45) of the seat element toward its front edge (42). The recess has a depth that gradually increases from each of the side edges (46) in the direction of the longitudinal axis. The recess has a lowest point (P) on the longitudinal axis and a cross-section along the longitudinal axis which has a section (C1) curving downward and forward and extending from the rear edge of the seat element toward the lowest point, and a section (C2) rising upward and forward and extending from the lowest point toward the front edge of the seat element. The section (C2) forms an acute angle with the horizontal plane and lies perpendicularly to the side of the ba ckrest supporting the back. Preferred Features: The acute angle is 12-18[deg].
