In the actuating position, the rotor acts in a switching manner on the switching element, as a result of which certain functions of the motor vehicle, such as switching on the ignition and the like. Like. Be effected.
  • Such ignition lock systems have also been further developed with a so-called "keyless go” functionality, in which it is sufficient for the user to carry the key, an identity (ID) transmitter, a chip card, a smart card or the like with him.

  • the ignition lock according to the invention has a separate handle which can be inserted into the rotor or another movement element of the ignition lock that can be moved in a suitable manner between the starting and actuating positions for the movement thereof.
  • a lock in the ignition lock interacts with the handle in such a way that the removal of the handle from the rotor or the movement element is blocked.
  • the handle in turn has an actuating element for releasing the lock, so that after actuation of the actuating element the handle can be removed from the rotor or the movement element.
  • an elastic force can act on the rotor in the actuation position. Because of this elastic force, which is, for example, a spring force, the rotor then automatically returns to the starting position as soon as the manual action on the handle stops.
  • an ignition lock designed in this way, starting from the starting position in one direction of rotation, the ignition for the motor of the motor vehicle is first switched on in a first actuation position. The engine is started in a subsequent second actuation position. Starting from the starting position in the other direction of rotation, the ignition for the engine is switched off in a third actuation position.
  • the handle can expediently be designed in the manner of an ignition key with a beard and a grip part.
  • the movement element can have a receptacle into which the beard used to insert the handle can be inserted.

  • the nose together with the slide is then moved out of the third section of the contour against the force of the spring with unlocking release.
  • a pushbutton for actuating the sliding element is preferably attached to the sliding element in the handle part.
  • the pushbutton together with the sliding element can be actuated manually against the force of a compression spring which is supported, for example, on the beard.
  • a compression spring which is supported, for example, on the beard.

  • the company logo of the motor vehicle manufacturer, the company logo of the manufacturer for the ignition lock or the like can be attached to the surface mentioned.
  • the handle is securely and captively locked in the ignition lock and can nevertheless be removed from the ignition lock.
  • the handle thus remains in the ignition lock and does not have to be removed when leaving the motor vehicle. Nevertheless, the handle can be loosened and removed from the ignition lock without additional aids if necessary.
  • the keyless go functionality fails, for example if there is a disturbance in the authentication of the electronic key required for starting the motor vehicle in the interior of the motor vehicle. Then emergency operation is possible in a convenient and simple manner by inserting the electronic key into the ignition lock instead of the handle, which then causes the immobilizer deactivated and the motor vehicle can be put into operation. Changes to the ignition lock itself are not necessary despite this additional functionality.
  • the electronic key has a transponder for transmitting a code.
  • the housing of the electronic key is generally made of plastic.
  • the handle can be made of metal, which can be more advantageous for its use.
  • Fig. 8 shows schematically the handle in the unlocked state and Fig. 9 is the view of the ignition lock in the direction of insertion of the handle, the handle being removed from the ignition lock.

  • the movement element 2 can be displaceable, rotatable or can be moved in some other suitable manner.
  • a movement element 2 which is designed to be rotatable in the manner of a rotor and which is considered in more detail below without limitation is particularly preferred.
  • the ignition lock 1 also contains at least one switching element 3, the rotor 2 having a switching effect on the switching element 3 in the actuating position.

Abstract

L'invention concerne une serrure de contact (1), notamment pour un système d'autorisation de rouler qui coopère, au moyen d'un signal de fonctionnement codé, avec une clé électronique ou similaire servant à l'authentification, ledit système étant installé dans un véhicule automobile. Cette serrure de contact (1) présente un élément de déplacement (2) mobile, pouvant passer d'une position initiale à au moins une position d'actionnement, ainsi qu'un élément de commutation (3). En position d'actionnement, l'élément de déplacement (2) agit sur l'élément de commutation (3) de façon à provoquer une commutation. Cette serrure de contact (1) présente en outre une manette (4) pouvant être introduite dans l'élément de déplacement (2) et servant au déplacement manuel de ce dernier. Un élément de verrouillage (5) coopère avec la manette (4), une fois cette dernière insérée, de façon à bloquer le retrait de la manette (4) introduite dans l'élément de déplacement (2). La manette (4) présente un élément d'actionnement servant à libérer l'élément de verrouillage (5) de sorte que, une fois l'élément d'actionnement actionné, la manette (4) puisse être retirée de l'élément de déplacement (2).
