  • a handle is preferably used in electric cars in which the handle with a powered drive element moves out of its flush or flush retracted position, in which the handle is arranged to reduce the air resistance, into the extended position when a legitimate operator approaches the motor vehicle. As soon as the handle is no longer needed, it moves back into the retracted position and thus disappears into the Body to avoid creating drag.
  • the invention is based on the object of creating a solution which provides a handle arrangement for a motor vehicle in a structurally simple manner, by means of which a blocking of the movement of the handle or a resistance to the movement of the handle at the beginning of the extension process can be overcome.
  • the object is achieved according to the invention in that the drive element, during operation, can execute a drive movement divided into the main deployment path and a pre-deployment path upstream of the main deployment path, the drive element during its drive movement along the front - Ausstellweges is formed motion decoupled from the main lever, and wherein a pre-deployment lever is rotatably mounted on the support housing, which is designed to push the handle in the direction of the extended position during the drive movement of the drive element along the pre-deployment path.
  • the invention provides a handle assembly for a motor vehicle is made available, which is through a simple construction and characterized by a special concept with regard to overcoming a blockage or resistance when moving the handle at the beginning of the extension process.
  • the pre-opening lever ensures that a leverage force is exerted on the handle in the direction of the extended position, which force acts before the force of the main opening lever. This makes it possible to apply a force to the handle before the start of the actual extension process, by means of which the handle is only moved a small distance in the direction of the extended position without the handle reaching the extended position. Rather, the slight movement of the handle before the actual extension movement with the aid of the pre-opening lever releases a resistance to movement or a possible blocking of the movement of the handle.

  • the first lever arm has a length which is at least twice the length of the second lever arm.
  • this embodiment uses the lever set so that the pre-opening lever exerts the greatest possible force on the handle. In contrast to the main opening lever, this force only has to act over a short movement path of the handle and at the same time also over a short movement path of the pre-opening lever, whereas the main opening lever, in contrast, has to cover a much longer distance to display the handle, so that the variability of the lever ratios for the main opening lever is severely limited.
  • a space-saving design is provided in a further embodiment of the invention in that the main opening lever is rotatably mounted on the carrier housing about an axis of rotation, the drive element being rotatably mounted about a motor-driven drive axis on the carrier housing and the drive movement of the drive element as a rotational movement around the Drive axis from a basic position in which the The handle is arranged in its retracted position, via a pre-extended position into a main extended position, in which the handle is arranged in the extended position.
  • the invention provides in an embodiment that the drive element is designed to rotate during its rotary movement along the pre-opening path in a first direction of rotation and along the main opening path in a second direction of rotation.
  • the first direction of rotation is opposite to the second direction of rotation, the drive element being designed to run through the basic position during its drive movement from the pre-open position into the main open position.
  • a query for example with the aid of a button, a microswitch or a sensor, of the position of the drive element and / or the handle is required, the drive element in this embodiment performing a kind of forward and reverse movement until the actual movement to the exhibition the handling takes place.
  • first direction of rotation and the second direction of rotation are identical.
  • interrogation means are not necessary, because the possible removal of a blockage and the extension of the handle involve a flowing and rectified movement of the drive element if the first and second directions of rotation are identical.
  • the drive element has a movement pin which is arranged at a radial distance from the drive axis, with the movement pin pressing against the main release lever during the drive movement of the drive element along the main opening path, the main -The opening lever rotates around the axis of rotation and the handle is designed to move into the extended position.
  • a movement decoupling for the main opening lever is possible in a structurally simple manner in that when the drive element moves along the pre-opening path, the movement pin is arranged at a distance from the main opening lever.
  • the drive element has a push pin, which is arranged at a radial distance from the drive axis, with the push pin against the first lever arm of the pre-deployment lever during the drive movement of the drive element along the pre-deployment path urging, rotating the pre-opening lever about the pivot axis and the handle is designed to move in the direction of the extended position.
