Abstract
Abstract A security system for a vehicle of the type having an engine with a starting switch movable between an OFF position and an engine START position includes an alarm module for disabling the engine and/or sounding an alarm in the event of an intrusion into the vehicle. Activating means activate the alarm module either automatically when the vehicle operator leaves the vehicle or in response to a signal from a transmitter in the operator's possession. The alarm module can be disarmed or deactivated without the transmitter by turning the engine starting switch from its OFF to its START position a selected number of times. A time delay may also be incorporated into the system so the disarm code may be a selected number of start attempts in combination with a selected time delay(s) before, during or after those attempts have been made.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
91 words
A security system for a vehicle having an engine with an ignition switch movable between an engine START position wherein said switch carries a current pulse and an OFF position, said system comprising vehicle securing means; actuator means for actuating the vehicle securing means; deactivating means responsive to a selected number of attempts to start the engine for deactivating the vehicle securing means, and means for disabling the deactivating means after a number of attempts to start the engine other than the selected number have been made a plurality of times.
Claim 2
Dependent Claim
91 words
A security system for a vehicle having an engine with an ignition switch movable between an engine START position wherein said switch carries a current pulse and an OFF position, said system comprising vehicle securing means; actuator means for actuating the vehicle securing means; deactivating means responsive to a selected number of attempts to start the engine for deactivating the vehicle securing means, and means for disabling the deactivating means after a number of attempts to start the engine other than the selected number have been made a plurality of times.
Claim 3
Dependent Claim
110 words
A security system for a vehicle having an engine with an ignition switch movable between an engine START position wherein said switch carries a current pulse and an OFF position, said system comprising vehicle securing means; actuating means for actuating the vehicle securing means, and deactivating means responsive to a selected number of attempts to start the engine for deactivating the vehicle securing means, said deactivating means including a counter for counting the number of current pulses caused by movements of said switch to the START position, said counter producing an output signal which deactivates the vehicle securing means when the counter has counted to the selected number of pulses.
Claim 4
Dependent Claim
110 words
A security system for a vehicle having an engine with an ignition switch movable between an engine START position wherein said switch carries a current pulse and an OFF position, said system comprising vehicle securing means; actuating means for actuating the vehicle securing means, and deactivating means responsive to a selected number of attempts to start the engine for deactivating the vehicle securing means, said deactivating means including a counter for counting the number of current pulses caused by movements of said switch to the START position, said counter producing an output signal which deactivates the vehicle securing means when the counter has counted to the selected number of pulses.
Claim 5
Dependent Claim
17 words
The system defined in claim 2 wherein the vehicle securing means includes means for preventing engine operation.
Claim 6
Dependent Claim
85 words
The system defined in claim 2 wherein the vehicle securing means include settable alarm means for producing, when set by an arming signal, an alarm indication in response to a trigger signal, an arming circuit which, when actuated, produces an arming signal to set said alarm means, and intrusion detection means for detecting an intrusion into the vehicle and providing a trigger signal to said alarm means in response thereto; said actuating means actuates said arming circuit, and said deactivating means deactivates said arming circuit.
Claim 7
Dependent Claim
24 words
The system defined in claim 4 wherein said vehicle securing means also include means for preventing engine operation when said alarm means are set.
Claim 8
Dependent Claim
43 words
The vehicle security system defined in claim 2 wherein the deactivating means also include delay means for delaying the deactivation of said vehicle securing means for a selected period of time before, during or after the selected number of pulses have been detected.
Claim 9
Dependent Claim
67 words
The system defined in claim 2 wherein the deactivating means also include a timer; means for applying one of said current pulses to start the timer, said timer thereupon emitting an output signal after a selected period of time. and means for detecting the presence simultaneously of said output signals from said counter and said timer and producing a deactivating signal which deactivates the vehicle securing means.
