A door handle assembly for a motor vehicle includes an operating handle, a mechanical coupling device, and a locking device attached to a handle mounting. An acceleration force can block an actuation of the closing assembly via the operating handle and/or the coupling device so that an unintended unlatching of the door closure during a vehicle accident is prevented. The locking device has a locking element, which is movably coupled to the mechanical coupling device by a connecting element, such that, a pivotal movement of the mechanical coupling device will rotate the locking element about a rotational axis. The locking element includes at least one locking member which is designed to block the rotational movement of the locking element when a predetermined displacement speed of the operating handle has been exceeded.
