Description

Door handle assembly Technical Field The invention relates to a door handle assembly for a motor vehicle, comprising an electromechanical door locking system with a door lock, a handle carrier which can be fastened to a motor vehicle door, and a handle element which is pivotally mounted on the handle carrier by means of a pivot axis and is configured to be manually actuated so as to be movable from a rest position into an actuated position for electronically unlocking the door lock or into an emergency actuated position for mechanically unlocking the door lock beyond the actuated position. Background Such door handle assemblies are known in the art. In such known door handle assemblies, the resistance means that increase the actuation resistance are effective at the end of the first actuation path of the manually actuated handle element, so that the switch for electronically unlocking the door lock is actuated after or when the perceptible pressure point is overcome and the door lock is electronically unlocked. The resistance means are here configured as spring elements, so that the required force that has to be applied by the user has increased for the electronic opening. If the handle element is deflected over the first actuation path along the second actuation path, the door lock is mechanically opened in an emergency situation, for example in the event of a run-out of the vehicle battery, wherein the actuation force that the user needs to apply for this purpose is considerably greater than the force that is required for the electronic opening. Because of the design of this known door handle assembly, a high actuation force is required to move the handle element both for the normal operating mode of the door handle assembly and for the emergency operating mode without electricity, which places an adverse limitation on the comfort of the door handle assembly. Disclosure of Invention The object of the present invention is to create a solution which in a constructively simple manner provides an improved door handle assembly by means of which the aforementioned disadvantages are overcome and which enables a user to operate the handle element comfortably. According to the invention, this object is achieved by a door handle assembly having the features according to claim 1. The motor vehicle door handle assembly according to the invention comprises an electromechanical door locking system with a door lock, a handle bracket which can be fastened to the motor vehicle door, a handle element which is pivotably mounted on the handle bracket by means of a pivot shaft, which is configured for manual actuation from a rest position to an actuating position for electronically unlocking the door lock or to an over-actuating position for mechanically unlocking the door lock, a stop element which is mounted on the handle element in a manner which can be moved between a basic position and an offset position, which is configured as a neck-shaped section which has a first longitudinal end and a second longitudinal end and which has a neck-shaped section which links the first longitudinal end to the second longitudinal end and which has a head section which is mounted on the second longitudinal end and which is configured to widen in comparison with the neck-shaped section, and an opposite stop element which is mounted on the handle bracket in a manner which can be moved between a blocking position and a release position, which is configured in a separated manner with a gap of variable width, wherein in the position of the element is arranged between the base element and the handle element and the base element is arranged in a window curtain which is arranged between the handle element and the handle bracket is arranged in the position by means of a stop force of the opposite neck-shaped section which is arranged between the handle element and the handle bracket and the base element is arranged in the position, the counter stop element, which is still arranged in its blocking position, is configured to inhibit movement of the handle element beyond the actuation position and the head section of the stop element, which is still arranged in its basic position, rests against a gap, which is configured to be narrower than the head section in the blocking position, and wherein the head section of the stop element, which is still arranged in its basic position, is configured to press the counter stop element from the blocking position into the release position, in which the gap is configured to be enlarged compared to the blocking position and to allow the head section to pass through the gap, when the handle element is manually moved in the direction of the emergency actuation position from the actuation position by means of a second user force, which is greater than the first user force. Advantageous and suitable designs and developments of the invention emerge from the respective dependent claims. The invention proposes a door han
