Device for starting a motor vehicle motor, using an electronic key

Abstract

The invention relates to a device for starting a motor vehicle motor. According to the invention, a slot is ( ) used for inserting ( ) the key ( ) which is usually closed by a spring-loaded cover ( ). The key ( ) is displaced in the slot ( ) into various key positions ( ), in order to control different functions of the motor or other ancillary devices in the vehicle. In order to ensure a compact construction which is easy to use, the inventive device prevents the key ( ) from turning in the slot ( ) and the key ( ) is displaced into at least three operating positions ( ) for the control functions which are axially staggered. After being inserted for a first operating distance ( ), the key takes up an initial position ( ), in which it is secured in the slot ( ) in a force-fit. In a subsequent second intermediate position, the key ( ) is secured in a positive fit which can be locked automatically. This prevents the manual withdrawal ( ) of the key ( ). In order to remove the key ( ), the latter is axially pushed into a third final position, in which the lock on the operating position can be released. During its course of operation, the key ( ) is axially spring-tensioned ( ) in the direction of the retaining position The operating position of the key ( ) determines the different vehicle functions.
