摘要:
A mechanical unlocking arrangement is integrated in an adjusting element for the unlocking and locking of a door- or lid-lock which in addition to a main adjusting drive includes a further power-actuated security-adjusting drive for blocking the adjusting member of the main adjusting drive in the position keeping the lock locked by means of a locking member; the mechanical unlocking arrangement thereby enables a release of the blocked adjusting member without power-assist.
摘要:
A method and device for the electrical control of a central locking system and of a mechanical securing device (that provides additional lock protection) for motor vehicles by a lock cylinder that interacts with at least two control switches. This method and device ensures a better utilization of the electrical control switches, in that, an unlocking control switch assigned to the unlocking of the central locking system and the deactivation of the mechanical securing device is switched in addition to a locking control switch assigned to the locking of the central locking system. If the lock cylinder is pivoted in the locking direction beyond its regular locking position, the resultant joint switching state of the two switching control devices is evaluated to activate the mechanical securing device.

A locking device for a door lock in a motor vehicle has a locking position which can be selected, even by remote actuation, by an outer security element and in which the influence of outer and inner lock handles and of inner security elements on this locking position is prevented as a result of an interruption of the force flux at disengageable couplings.
摘要:
A control arrangement for a combined central locking and burglar alarm system for motor vehicles is constructed in such a manner that an accidentally tripped false alarm can be deactivated in a single manner by a designated key and a key detection switch associated with a door locking cylinder, so that the activation state of the burglar alarm system is automatically adapted to the existing locking state of the central locking system.
摘要:
A process and device for controlling a motor vehicle central locking system that has multiple station operation from the driver's door and from the trunk lid. A central locking of the door locks of the motor vehicle is avoided when mechanically securing the lock of the trunk lid against opening from the outside without a key in the unlocked state. This is done by switch-controlled suppression of the effect of the locking control signal normally generated when locking.

An anti-theft device for a car radio having a theft module, which renders the car radio inoperative when the radio is slid out of its installation recess in the vehicle, is provided by a joint housing for a power supply and anti-theft protection plug connection elements, as well as for a change-over switch controlling the theft module. The housing is fastened via the plug connection elements at the rear wall of the car radio such that the change-over switch is inevitably actuated by the frame of the installation recess during the sliding-out of the radio.

In a failsafe method and apparatus for signalling theft for a motor vehicle, an item of theft-signalling information is produced as a function of the signal state of at least one of a plurality of monitoring signals, which are indicative of vehicle states. According to the invention, the theft-signalling information is produced only if the signal states of a plurality of monitoring signals are present in one of one or more prescribed theft-signalling combinations. Each theft-signalling combination comprises one or more signalling conditions, which succeed one another in a specific time sequence and which signalling conditions themselves comprise one or more theft indicative combinations of jointly interrogated signal states of associated monitoring signals.

An alarm system having improved acoustic signal transmitting capability is provided for motor vehicles. The radio speaker system of the vehicle is employed for both passenger listening and for warning signal transmission in the event of unauthorized intrusion or attempted theft. The speakers occupy their usual installation positions in a vehicle, such as horizontally mounted in the dashboard, when used for the purpose of listening to a radio or tape. When the vehicle is unoccupied, and theft or tampering are attempted, an alarm system is activated which causes a control element to swivel the speaker into a position parallel to an external surface of the vehicle. Due to this repositioning of the speaker, reflection of an alarm signal back into the interior of the vehicle is minimized, and transmission of the alarm signal to the outside of the vehicle is optimized.

In a process for marking industrial products or parts, a plurality of spot welds serve as carriers of characterizing information, especially in encoded information. Information is encoded in said spot welds by varying the position of each weld relative to a reference position.
摘要:
A theft protection system for an installation unit recessed in an installation passage protects the installation unit mechanically and by an electrically initiated alarm by permitting the installation to be pulled out of the installation passage to a distance limited mechanically by a movable protection stop and by actuating an electrical theft protection contact within this distance by utilizing the relative motion between the installation unit as an installation retention arrangement and the installation passage to initiate the alarm.
