Description

Door handle arrangement of a vehicle door

The invention relates to a door handle assembly of a

Vehicle door, comprising a fastened to the vehicle door handle carrier, a handle mounted on the handle handle, which is aligned flush with an outer contour of the vehicle door in a non-use position and which is designed for operation by an operator in an actuating position movable, a first lever mechanism, which with a second lever mechanism coupled in movement with a second longitudinal end of the handle, the handle being coupled in a first longitudinal end of the handle;

Actuating position shifted in parallel compared to the non-use position and compared to the outer contour of the

Vehicle door is projecting and can be actuated by the operator to open the vehicle door, and wherein the first lever mechanism has a first pivot axis, which on the

Handle carrier is arranged.

Door handle assemblies in which the handle in their

Non-use position flush with outer contour of the

Vehicle door runs are known from the prior art. In this case, in the case of such door handle arrangements for a vehicle door of a motor vehicle, the handle can be designed as an inner or outer handle, wherein the present invention relates to a door handle arrangement for an outer handle. For such

Door handle assemblies have a variety of different constructions and embodiments. The inventive

Door handle assembly refers to those constructions in which a handle carrier on the back of the vehicle door, i. inside the motor vehicle, is attached. The at the

Handle-mounted handle is available at such

Embodiments usually protrude from the vehicle door and interfere with both the aesthetic appearance of the vehicle and the vehicle aerodynamics. In order to avoid these disadvantages, door handle arrangements are known from the prior art, in which the outside of the handle in its non-use position, ie in which it is not needed, approximately flush with the outer contour of the vehicle door, so strakbündig runs. Such a handle is for opening the vehicle door or a vehicle-mounted lock in an operating position

convertible, in which the handle protrudes from the outer contour of the vehicle door. The handle is extended by a motor when a legitimate operator approaches the vehicle. Once the handle is no longer needed, it returns to the non-use position and thus disappears into the body, so as not to create air resistance. The

Movement of the handle is known to be realized with the aid of a first lever mechanism and a second lever mechanism, which the respective longitudinal ends of the handle with the
