Einrichtung zum Verriegeln und Entriegeln einer Tür

摘要

The invention relates to a device for locking and unlocking a door of an object (O), especially of a motor vehicle, comprising a transmitting unit (S) arranged on the object (O) and a responding unit allocated to a user. An increased security is thus achieved such that the field of the transmitting lobe (SK1) formed by the transmitting unit or the field of the signals generated by the responding unit can be reduced or interfered in a reachable space of said field by means of a switching device (U) when the transmitting lobe (SK1) is orientated on the interior space (I) of the object (O). This is carried out such that a responding unit located in the passenger area of the interior space (I) is not interrogated.
