The invention relates a door handle unit (10) for actuating a lock (101) of a movable part (100) of a motor vehicle, particularly a door, a flap or the like, with a door handle (11), which is movably mounted at the support element (12) for mechanically opening the movable part (100) by a user, wherein the door handle (11) comprises at least a rest position and a operative position, a mechanical coupling element (13), which is movably mounted at the support element (12) and by which a movement of the door handle (11) is transmitted to the lock (101) from the rest position to the operating position, wherein the door handle (11) and the coupling element (13) are mechanically cooperating and form a movable actuating mechanism (15), and at least a locking unit (16), which in a normal case enables a movement of the actuating mechanism (15) for actuating the lock (101) and only in a case of locking blocks a movement of the actuating mechanism (15) for actuating the lock (101).According to the invention it is provided that the blocking unit (16) can be activated for a case of blocking (Ib) via a remarkable movement of the actuating mechanism (15).
