Said bearing body (34, 36) comprises sliding elements (40) that interact with the curved area (28) and slide along said curved area (28). Said blocking device comprises at least one actuating button (46), notches (54) that are arranged on the curved area (28) of the bar (24), and least one blocking element that normally engages with the blocking bar and can be disengaged by actuating the actuating button (46).
