  • the in Figure 2 The outside door handle 10 shown is mounted immovably on the movable part 1 and is therefore designed as a fixed outside door handle 10. At least one or two or all of the storage means of the fastening device 80 can be designed as a fixed bearing at the at least one storage point 81. The at least one storage point 81 thus forms a fixed storage point.
  • the deformation area 40 is marked. It can be seen that an outside 20.2 of the wall 22, which is normally visible from the outside by an operator 5, is designed as a flat and closed surface of the outside door handle 10. The deformation area 40 is therefore not visible to the operator 5 from the outside.

  • the deformability of the wall 22 in the deformation area 40 differs in particular from the deformability of areas of the wall 22 outside the deformation area 40, whereby the sensor device 30 is not moved in the same way during an activation action as the wall 22 in the deformation area 40. If the sensor device 30 is independent is supported by the deformation region 40 at at least one sensor mounting point 33, a structural adjustment 50 is not absolutely necessary. Even if there is no recess 50, due to the storage of the sensor device 30, regardless of the Deformation area 40 can be achieved so that the deformation of the door handle body 20 can be detected by the inductance measurement. The structural adjustment 50 causes a further increase in the sensitivity of the measurement.
  • the sensor device 30 is arranged on a circuit board 31 and/or is electrically connected to further electronics.
  • the sensor device 30 is attached to a holding device 32.
  • the holding device 32 is designed such that a deformation in the deformation area 40 due to the activation action essentially does not affect the position of the sensor device 30 in the interior 20.3.

  • the activating agent 60 is designed here in particular as a coating on the wall 22. If an operator 5 now reaches into the recessed grip 21 around the door handle body 20 and exerts a force in the deformation area 40, the wall 22 is deformed in the deformation area 40. This deformation also causes a deformation of the activating means 60 and/or a reduction in the Distance D between the activation means 60 and the sensor device 30 takes place.

Additionally or simultaneously, the application of force, ie the activation action, in the deformation region 40 can be detected by the sensor device 30. It is, for example, conceivable that both the sensor device 30 and the actuation of the outside door handle 10 by a movement in the direction of the arrow activate a function of the vehicle 3, e.g. B. causes the electric lock 2 to open.
  • the activating agent 60 is here z. B. designed as an electrically conductive plate.

  • an outside structural adjustment 50 is provided on at least one outside 20.2 of a wall 22 of a door handle body 20 of the outside door handle 10 according to the invention.
  • This has the advantage that the deformation area 40, on which an activation action in particular is carried out by an operator 5, can be recognized by the operator 5.
