Arrangement for locking a data carrier device data exchange and secure startup command of a vehicle.

摘要

Arrangement (10) for data exchange between a support of rigid data (12), or semirigid, and a device (14) exchange data, in particular data read on the media, which equips a motor vehicle whose functions partial or total antitheft are guaranteed by the data processing being contained some of this data in the data carrier (12), which are representative of an authorized user or a group of authorized users of the vehicle, comprising the provision a unit (14, 16) in which the support (12), in particular generally identification is manually entered from back to front in a housing (16) of the unit (14), in which the device (14) comprises means (28, 38) for longitudinally retaining the data carrier in an active position in the unit, in which arrangement the data medium (12) comprises, on one edge (24) of longitudinal orientation, a mue sca side (28) locking, and the unit comprises a lever (38) locking the support (12) which is mounted rotatably about an axis (A) perpendicular to the direction (I) longitudinal insertion of the data carrier ( 12) in the unit, between a locking position in which a free end of the locking lever (38) forming a locking finger (42) extends into the locking notch (28), and located out of the notch (28) to allow removal of the data carrier (12), from front to back, out of the box (14), and in which arrangement the rotation of the locking lever (38) between its positions withdrawal and locking is controlled by a control button (30, 36) which is displaceably mounted relative to the unit (14) which is connected (44) to the locking lever (38) and is associated with a switch start-stop (64) which controls an electrical starting circuit of the vehicle, characterized in that the unit (14, 54 ) Comprises at least a first electric switch (60) allowing the supply of electric starting circuit of the vehicle and activating the data carrier (12, 26) during its introduction, from back to front, in the unit, wherein the control button (30, 36) mounted displaceably relative to the unit in a direction (a) substantially perpendicular to the longitudinal direction (I) of introduction of the data carrier (12) in the unit (14).
