Abstract
Abstract An improved collision sensor for vehicles comprising a sensor adapted to extend beyond the main body of the car for a distance dependent upon the speed at which the car is travelling and responsive to contact pressure for activating a safety mechanism within the car, and a displacement mechanism for controlling the displacement of the sensor beyond the main body of the car as a function of the car''s speed.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
109 words
An improved collision sensor for vehicles comprising a sensor located at the end of a rod adapted to extend the sensor beyond the bumper and main body of the vehicle for a distance dependent upon the speed at which the vehicle is traveling, said sensor being responsive to contact pressure for activating a safety mechanism that secures a passenger to his seat within the vehicle, and means for controlling the displacement of the rod so as to extend the sensor beyond the bumper and body of the vehicle as a function of the vehicle''s speed to permit early activation of the safety mechanism in the event of a collision.
Claim 2
Dependent Claim
109 words
An improved collision sensor for vehicles comprising a sensor located at the end of a rod adapted to extend the sensor beyond the bumper and main body of the vehicle for a distance dependent upon the speed at which the vehicle is traveling, said sensor being responsive to contact pressure for activating a safety mechanism that secures a passenger to his seat within the vehicle, and means for controlling the displacement of the rod so as to extend the sensor beyond the bumper and body of the vehicle as a function of the vehicle''s speed to permit early activation of the safety mechanism in the event of a collision.
Claim 3
Dependent Claim
28 words
The improvement as in claim 1 wherein the collision sensor comprises an electrical contact responsive to contact pressure for permitting electrical current to flow to the safety mechanism.
