  • Patent number: 8454062
    Abstract: The invention relates to a handle device for a vehicle door, comprising an outer shell with a metal layer at least on the side facing away from the vehicle door and a cavity in which a sensor system for the keyless activation of a locking and unlocking system is arranged. According to the invention, the outer shell (4) has a free surface (7) with no metal layer, provided with a first sensor element (6a) arranged in the sensor system (6a, 6b, 6c), which has a touch- or proximity-sensor embodiment.

  • Patent number: 7866714
    Abstract: An exterior door handle for a motor vehicle, including an electromechanical locking system and a manually actuated handle part that can perform a lifting movement in order to open a door lock. The lifting movement of the handle part is subdivided, a device generating an increased actuation resistance and a switch electrically opening the door lock at the end of a first lifting distance. The handle part can travel an additional lifting distance beyond the first lifting distance in case the electric power supply is interrupted or the electric locking system breaks down, the additional lifting distance mechanically opening the door lock.

    Abstract: Disclosed is an exterior door handle (1) for a motor vehicle, comprising an electromechanical locking system (2) and a manually actuated handle part (3) that can perform a lifting movement in order to open a door (11) lock (8). The lifting movement of the handle part (3) is subdivided, a device (9) generating an increased actuation resistance and a switch (20) electrically opening the door lock (8) at the end of a first lifting distance (21). The handle part (3) can travel an additional lifting distance (23) beyond the first lifting distance (21) in case the electric power supply is interrupted or the electric locking system (2) breaks down, said additional lifting distance (23) mechanically opening the door lock (8).

  • Publication number: 20050219043
    Abstract: Locking system for a vehicle, in which a locking/unlocking function can be initiated by the activation of at least one capacitate sensor located on an external handle of the vehicle entry, wherein the sensor includes at least a second control surface not accessible to the user or accessible only with difficulty, via which the impact of environmental influences on the sensor by can be distinguished from the activation of the sensor by the user through detection of control surface selective signal changes at the sensor.

  • Patent number: 6648382
    Abstract: An outer door handle for vehicles has a stationary housing in the vehicle door. The handle has a handle arm and acts on a lock arranged within the door. A pivotable latching member serves as a mass latching mechanism and makes the handle actuatable in a release position. Because of its inertia in a crash situation, the latching member reaches an active support position and blocks the handle. The pivot bearing for the latching member is located on the stationary housing. The movable handle arm has a shoulder. A counter shoulder is provided on the latching member. The folding movement path of the shoulder on the handle arm is intersected by the pivot movement path of the counter shoulder. In a crash situation the shoulder comes to rest against the counter shoulder. In the release position, the shoulder passes the counter shoulder upon handle actuation.

  • Patent number: 6619709
    Abstract: The invention relates to a door handle, comprising a handle located on the visible side of the door and a support (10) for said handle which is fixed onto the reverse side of the door. The handle has connecting elements at both extremities which penetrate recesses in the door, whereby one extremity is connected to a lever (13′) which is mounted on a pivoting support (10). A housing which can contain a locking cylinder is inserted into the support (10) next to the handle. According to the invention, in order to simplify the assembly of the handle, a retaining element (25) is positioned between the support (10) and the lever (13′) which, in its usual active retaining position, secures the lever in a defined pivoted position, pointing outwards. The handle can be connected easily to the lever in this pivoted position. However, when the housing is inserted into the support, the retaining element (25) is displaced into its inactive position, where it releases the lever (13′).

  • Patent number: 6439626
    Abstract: An actuator for a vehicle door lock has an exterior handle with a flap and an inner support on which the flap is pivotally supported. The flap has stays with connecting points penetrating an opening in the vehicle door. A first connecting point has a pivot pin and a pivot seat. When inserting the pivot pin into the pivot seat, the handle is in an angular position relative to its final fastening position. The pivot seat has an inner shoulder engaged by a radial projection of the pivot pin for axially securing the pivot pin. The second connecting point has a first part on the handle and a second part on the flap. The handle is rotated back from the angular position until the first and second parts of the second connecting point are radially aligned. They are then connected to one another and the final fastening position of the handle is determined.
