Abstract
Abstract A collision damage reduction system to reduce contact velocities between a vehicle and a collidant by use of air bags on the exterior of the vehicle. The vehicle operator or an automatic collision imminence detection system e.g. radar, sonar, or an accelerometer and controller actuates a switch that actuates the air bag inflators when a collision is perceived imminent. The switch or controller can also interrupt vehicle motive power and actuate the brakes. The air bag has vents and shapes to steer it and its collidants. The controller can also actuate vehicle horns and lights to warn collidants when imminent collisions are detected.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
117 words
A method for minimizing damage and injury to a vehicle, to occupants of said vehicle, and to collidants of said vehicle, during a collision comprising the steps of: a. detecting the imminence of a collision by radar or driver's sight, b. inflating long air bags on an exterior surface of said vehicle before contacting said collidants, c. keeping a portion of said air bags on the ground before and after contacting said collidant, and d. compressing said air bags between said vehicle and said collidant to reduce the velocity of said collision, whereby reducing velocities of said collision of said vehicle and said collidant will reduce damage and injury to said vehicle, said collidant, and said occupants.
Claim 2
Independent Claim
117 words
A method for minimizing damage and injury to a vehicle, to occupants of said vehicle, and to collidants of said vehicle, during a collision comprising the steps of: a. detecting the imminence of a collision by radar or driver's sight, b. inflating long air bags on an exterior surface of said vehicle before contacting said collidants, c. keeping a portion of said air bags on the ground before and after contacting said collidant, and d. compressing said air bags between said vehicle and said collidant to reduce the velocity of said collision, whereby reducing velocities of said collision of said vehicle and said collidant will reduce damage and injury to said vehicle, said collidant, and said occupants.
Claim 3
Dependent Claim
21 words
The method of claim 1, further including the step of actuating brakes of said vehicle in response to said detecting step.
Claim 4
Dependent Claim
24 words
The method of claim 1, further including the step of interrupting a motive power circuit to said vehicle in response to said detecting step.
Claim 5
Dependent Claim
25 words
The method of claim 1, further including the step of releasing air from said air bag at a controlled rate following contact with said collidants.
Claim 6
Dependent Claim
118 words
A collision damage reduction system for a vehicle comprising: a. air bags and inflators adapted to inflate outside said vehicle, b. a slant on a portion of the front face of said air bags to deflect oncoming air upward and thereby provide a thrust force to keep a portion of said air bags on the ground after inflation but before said air bags contact a collidant, and c. a manual switch in the driver's compartment to actuate said inflators before a collision, said manual switch actuated by an occupant of said vehicle, whereby the inflated air bags will compress between said vehicle and the collidant and reduce the velocity of said collision and thereby reduce damage and injury.
Claim 7
Dependent Claim
118 words
A collision damage reduction system for a vehicle comprising: a. air bags and inflators adapted to inflate outside said vehicle, b. a slant on a portion of the front face of said air bags to deflect oncoming air upward and thereby provide a thrust force to keep a portion of said air bags on the ground after inflation but before said air bags contact a collidant, and c. a manual switch in the driver's compartment to actuate said inflators before a collision, said manual switch actuated by an occupant of said vehicle, whereby the inflated air bags will compress between said vehicle and the collidant and reduce the velocity of said collision and thereby reduce damage and injury.
Claim 8
Dependent Claim
26 words
The collision damage reduction system of claim 5, wherein said manual switch includes means for automatically actuating the brakes of said vehicle prior to said collision.
Claim 9
Dependent Claim
27 words
The collision damage reduction system of claim 5, wherein said manual switch includes means to automatically interrupt motive power circuit to said vehicle prior to said collision.
Claim 10
Dependent Claim
37 words
The collision damage reduction system of claim 5, further including a radar or sonar using any suitable wavelength of electromagnetic or sonic radiation to detect imminent collisions and a controller for actuating said inflators on said vehicle.
Claim 11
Dependent Claim
