Abstract

A GROWING NUMBER OF CHILDREN AND FRAIL ADULTS WERE KILLED BY
THE SUDDEN DEPLOYMENT OF AIRBAGS IN LOW VELOCITY CRASHES.
SOURCE: U.S. DEPARTMENT OF TRANSPORTATION DOCKET 74-14 DATE

A KEY FACTOR WAS THE VICTIM'S PROXIMITY TO THE DEPLOYING AIRBAG.
INTRODUCTION OF EXTERNAL AIRBAGS TO SUPPLEMENT THE PRESENT
SYSTEM WOULD OFTEN ELIMINATE THE NECESSITY OF INTERNAL AIRBAG
DEPLOYMENT IN LOW VELOCITY CRASHES.
THE MOST OUTSTANDING FEATURE IS THAT DEPLOYMENT WOULD TAKE
PLACE A FRACTION OF A SECOND BEFORE THE COLLISION.
THIS WILL EITHER PREVENT THE ACCIDENT OR GREATLY REDUCE ITS
SCOPE.
DESCRIPTIONS WILL INCLUDE MANUAL AS WELL AS LASER-COMPUTER
DIRECTED VISUAL DEPLOYMENTS THAT WILL ACTIVATE ONLY IN
INESCAPABLE COLLISION SITUATIONS.
APPLICABILITY: CARS, TRUCKS, TRAINS, TRAILERS SNOWMOBILES ETC.

Description

EXTERNAL AIRBAGS FOR CARS TRUCKS AND TRAILERS
A TEN TON TRUCK IS MOVING ALONG A ROAD AT 40 MILES AN HOUR.
SUDDENLY A SMALL BOY CHASING A BALL RUNS ACROSS THE PATH OF
THE TRUCK TOO LATE FOR THE DRIVER TO BRAKE IN TIME THE DRIVER
PULLS A MANUAL SWITCH AND DEPLOYS A LARGE EXTERNAL AIRBAG
THAT INFLATES IN 2/lOths OF A SECOND.
THE BOY IS DEFLECTED TO ONE SIDE INSTEAD OF BEING CRUSHED
TO DEATH BY THE WHEELS OF THE TRUCK.
DEPLOYMENT TIME FOR INTERNAL AIRBAGS IS APPROXIMATELY l/lOth OF A SECOND. THE EXTERNAL AIRBAGS WILL BE LARGER AND MUCH
STRONGER THEN THE INTERNAL AIRBAGS.THE DEPLOYMENT TIME OF 2/lOths OF A SECOND IS AN ESTIMATE.
AT THE PRESENT TIME THE U.S. DEPARTMENT OF TRANSPORTATION'S
NATIONAL HIGHWAY TRAFFIC SAFETY ADMINISTRATION IS RECOMENDING
LOWER LESS AGGRESSIVE DEPLOYMENT TIMES FOR INTERNAL AIRBAGS.

IS A SUBSTANTIAL NUMBER OF SMALL CHILDREN AND FRAIL ADULTS
KILLED BY THE POWERFUL FORCE OF THE AIRBAGS DURING THE DEPLOYMENT
PROCESS DURING RELATIVELY LOW SPEED CRASHES.
EXTERNAL AIRBAGS
EXTERNAL AIRBAGS WILL BE LOCATED OUTSIDE THE VEHICLE AND CAN
BE DEPLOYED WITH MUCH GREATER SPEED AND FORCE SINCE THEY DO
NOT COME INTO CONTACT WITH THE BODY OF THE CHILD DURING THE
DEPLOYMENT PROCEDURE.
THE INTERNAL AIRBAGS WILL SELDOM REQUIRE DEPLOYMENT DURING
LOW SPEED CRASHES AND CAN BE DEPLOYED LESS AGGRESSIVELY AND
A FRACTION OF A SECOND LATER DURING SEVERE HIGH SPEED COLLISIONS.

AIRBAG FILL UP SPEED:
WHEN A CAR EQUIPPED WITH AN AIRBAG IS INVOLVED IN A
COLLISION A SENSING DEVICE CALLED AN ACCELEROMETER IS
THE TRIGGER THAT INFLATES THE AIRBAG. THIS DEVICE IS
LINKED TO A CYLINDER OF COMPRESSED AIR WHICH INFLATES
THE AIRBAG IN l/lOth OF A SECOND. THE INTERNAL AUTOMOBILE
AIRBAG IS DESIGNED TO IMMEDIATELY DEFLATE AFTER A COLLISION
SO THAT THE DRIVER WILL NOT GET TRAPPED.
THE EXTERNAL AIRBAG WILL NOT DEFLATE AFTER THE EVENT.
WILL THERE BE ANY UNNECESSARY DEPLOYMENT:

14.6 FEET LONG AND SLIGHTLY WIDER THAN THE TRUCK IN
WIDTH.THE VELOCITY OF THE TRUCK WILL DETERMINE THE
AREA OF COVERAGE ACCORDING TO THE TABLE SHOWN
IF THE CHILD MANAGED TO RUN ACROSS THE PATH OF THE
MOVING TRUCK BEFORE THE 14.6 ZONE WAS REACHED THEN
NO DEPLOYMENT WOULD TAKE PLACE

MARK DEPLOYMENT WOULD STILL BE INCOMPLETE BUT THE EXPANSION
BE FROM BELOW THE BUMPER IN AN UPWARD
ROLL PREVENTING HIM FROM GOING UNDER THE WHEELS AND
SHOOTING HIM TO THE LEFT OR THE RIGHT OF EITHER AIRBAG.

WOULD DEPLOY FROM A MUCH CLOSER DISTANCE.
FINAL WARNING LASERS:
LASERS SITUATED ABOVE THE CAB OF THE TRUCK JUST
OVER THE WINDSHIELD ARE BEAMED ON THE AREA THAT
IS JUST BEYOND THE DEPLOYMENT ZONE
THE FINAL WARNING LASERS CAN DISTINGUISH IF AN
OBJECT LIKE ANOTHER VEHICLE IS MOVING IN THE SAME
DIRECTION IS STATIONERY OR MOVING TOWARDS THE TRUCK.
THE DRIVER WILL NOT HAVE TO FOCUS ON THE PANEL SCREEN
WHILE DRIVING BUT A WARNING BUZZER WILL INFORM HIM
OF OBSTRUCTIONS IN THE FINAL WARNING ZONE.
EXAMPLE:
ANOTHER TRUCK CARRYING LONG STEEL PIPES IS INVOLVED
IN A MAJOR ACCIDENT. ONE OF THE PIPES COMES FLYING
THROUGH THE AIR TOWARDS THE WINDSHIELD OF THE FIRST
TRUCK.

THE COMPUTER DIREDTED LASERS WILL DEPLOY BOTH THE
INTERNAL AND THE EXTERNAL AIRBAGS SINCE THE LIFE OF
THE DRIVER WAS IN DANGER.IF THE SAME PIPE WAS
FIRED AT A LOW LEVEL JUST TWO FEET FROM THE GROUND
THE PROGRAM WOULD DEPLOY ONLY THE EXTERNAL AIRBAG.

DIAGRAM:
ALTHOUGH OBJECT VEHICLE (A) IS INSIDE THE COLLISION FIELD
OF HOST VEHICLE (B) THERE WILL BE NO AIRBAG DEPLOYMENT
SINCE THEIR RELATIVE VELOCITIES ARE VERY CLOSE.
IF THERE WAS A DRAMATIC AND SUDDEN CHANGE IN THIS RELATIVE
VELOCITY WHICH THE COMPUTER CALCULATES AS AN INESCAPABLE
COLLISION RESOLUTION ACCORDING TO THE FIVE PROGRAM CODES
AND THE COMPUTER-LASER IMAGE ON THE VEHICLE SCREEN THE
NECESSARY AIRBAGS WILL BE DEPLOYED.

THE LASER IMAGE EVALUATER
THE LASERS GIVE A FAIRLY CLOSE OUTLINE OF ANY OBJECT
THAT ENTERS ITS FIELD.
WHEN THE LASERS ESTABLISH THAT THE ENTRY INSIDE THE
DEPLOYMENT ZONE IS A CHILD AND NOT THE EDGE OF ANOTHER
VEHICLE MOVING IN A PARALLEL DIRECTION THE AIRBAGS
WILL DEPLOY WITH THREE FACTORS SATISFIED. THE SPEED
THE PROXIMITY AND THE SHAPE.

THE TRAVEL RECORD AND AIRBAG DEPLOYMENT TAPE

VEHICLE (C) A POLICE CAR SUSPECTS VEHICLE (B) TOOK
PART IN A BANK ROBBERY FOLLOWED BY A HIGH SPEED
CHASE.
THE OFFICERS WILL STOP VEHICLE (B) AND ASK FOR THE

ACTIVATES AIRBAG DEPLOYMENTS.

DEPLOYMENT PROGRAM CODES FOR EXTERNAL AND INTERNAL AIRBAGS
__________________________________________________________ 1: HOSTILE MOVEMENT IN A COLLISION FIELD
MEANS THAT THE HOST VEHICLE IS BOUND TO CRASH INTO A
VEHICLE OR OBJECT THAT CAN DO SIGNIFIGANT HARM TO THE
HOST VEHICLE.
THIS MEANS THAT BOTH THE EXTERNAL AND INTERNAL AIRBAGS
WILL RECEIVE THE FIRST DEPLOYMENT CODE FOR ALL SYSTEMS.

2: ENTRY OF A DEFENSLESS OBJECT INSIDE THE COLLISION ZONE.
THIS MEANS THE DEFENSELESS OBJECT LIKE THE CHILD WOULD
TRIGGER DEPLOYMENT OF AN EXTERNAL AIRBAG BUT THE FORCE
IS CONSIDERED TOO SMALL TO DEPLOY THE INTERNAL AIRBAGS.

3: RELATIVE MOVEMENT OF HOST VEHICLE TO THE OBJECT.
THIS MEANS THE DIFFERENCE IN VELOCITY OF THE HOST VEHICLE
TO THE OBJECT INSIDE THE COLLISION FIELD.
FOR EXAMPLE IF THE HOST VEHICLE AND THE OBJECT ANOTHER
CAR IN FRONT OF THE HOST VEHICLE ARE BOTH INSIDE THE
COLLISION ZONE BUT BOTH VEHICLES ARE MOVING AT THE
SAME SPEED OR A VERY SMALL DIFFERENCE THE AIRBAGS WILL
NOT DEPLOY SINCE THE DIRECTION OF MOVEMENT IS THE SAME
AND THE SPEED IS THE SAME SO THERE WILL BE NO COLLISION.
INSTEAD THE AUDIO SYSTEM WILL WARN WITH LOUD BEEPS TO TELL
THE HOST VEHICLE TO SLOW DOWN AND LET THE OBJECT VEHICLE
MOVE SAFELY AHEAD.

4: HOSTILE PROXIMITY.
THIS MEANS THAT OBJECTS IN A COLLISION FIELD SHOW A LARGE AND
ALARMING DIFFERENCE IN VELOCITY TOWARDS EACH OTHER.
THIS MAY BE CAUSED BY THE OBJECT EITHER STOPPING OR GREATLY
DECELERATING WHICH IN BOTH CASES WOULD MEAN A COLLISION
OF THE HOST VEHICLE WITH CONSIDERABLE FORCE.
THE IMENDING COLLISION WILL ALWAYS DEPLOY AN EXTERNAL
AIRBAG BUT THE INTERNAL AIRBAG DEPLOYMENT WILL BE DETERMENED
BY THE FOLLOWING CODE:

5: THE EXPECTED PROBABLE FORCE OF THE IMPENDING COLLISION.
AN ANALYSIS OF THE LASERS OUTLINE OF THE OBJECT AND THE
COMBINED VELOCITIES OF THE TWO VEHICLES WILL INFORM THE
COMPUTER THE PROBABLE COLLISION FORCE TO BE EXPECTED.
NOTE:
THE DEPLOYMENT RANGE IS TAILOR MADE FOR EACH CLASS OF VEHICLE.

CAR WOULD QUALIFY FOR DUAL SYSTEM AIRBAG DEPLOYMENT.
A MOOSE IN THE COLLISION ZONE OF A VERY LARGE TRUCK WOULD BE
A DEFENSLESS OBJECT IN A COLLISION ZONE AND CONSEQUENTLY
ONLY EXTERNAL AIRBAGS WOULD REQUIRE DEPLOYMENT.

t EXTERNAL AIRBAGS FOR TRAILERS AND TANKERS
SITUATION 1:
A LARGE TANKER TRUCK CARRYING DANGEROUS CHEMICALS IS MOVING
ALONG A HIGHWAY BY THE INTERSECTION OF A HILLY ROAD.
A SCHOOL BUS FILLED WITH CHILDREN IS COMING DOWN THE INTERSECTING
ROAD WHEN IT HITS A PATCH OF ICE AND STARTS HURTLING OUT OF
CONTROL TOWARDS THE TANKER TRUCK.
BOTH OF THE DRIVERS SEE EACH OTHER BUT BECAUSE THE TANKER IS
IN A TRAFFIC JAM HE CAN'T MOVE BACKWARDS OR FORWARDS.
THE BUS FILLED WITH SCREAMING CHILDREN CRASHES INTO THE TRUCK
WHICH EXPLODES AND BURNS KILLING HALF THE CHILDREN AND
BLOCKING THE HIGHWAY FOR SEVERAL HOURS.

SITUATION TWO:
IN THIS SITUATION THE SCHOOL BUS SPINS COMPLETELY AROUND
ON THE ICE PATCH AND THE SCHOOL BUS IS HURTLING TOWARDS
THE TANKER TRUCK BACKWARDS.
THE TRUCK DRIVER PULLS A RELEASE SWITCH AND TWO OR THREE
LARGE EXTERNAL AIRBAGS ALONG THE SIDE OF THE TANKER TRUCK
INFLATE IN 2/lOths OF A SECOND AND THERE IS NO EXPLOSION.
SITUATION:3 SEEING THE ONCOMING DISASTER THE SCHOOL BUS DRIVER PRESSES
A MANUAL RELEASE SWITCH AND A LARGE EXTERNAL AIRBAG INFLATES
FROM UNDER THE FRONT BUMPER OF THE BUS.
THE TRUCK DRIVER ALSO RELEASES HIS EXTERNAL AIRBAGS AT THE
SAME TIME AND THE TWO SETS OF HELIUM INFLATED AIRBAGS COLLIDE
WITH EACH OTHER THUS AVERTING A MAJOR ACCIDENT.

EXTERNAL AIRBAGS FOR SNOWMOBILES

EACH WINTER THERE ARE SEVERAL SNOWMOBILE FATALITIES
THAT RESULT WHEN A SNOWMOBILE MOVING OVER AN ICE
COVERED LAKE OR RIVER BREAKS THROUGH THE ICE AND
THE DRIVER IS DROWNED.
AN EXTERNAL AIRBAG WILL BE SITUATED UNDER THE SEAT
OF THE DRIVER THAT WILL DEPLOY BY FLICKING A SWITCH
NEAR THE STEERING WHEEL.
THE DEPLOYMENT MECHANISM IS IN A WATERPROOF HOUSING
AND CAN DEPLOY UNDER WATER LIFTING THE SNOWMOBILE
AND ITS RIDER TO THE SURFACE.
THE LARGE HELIUM FILLED AIRBAG WILL DEPLOY IN 2/lOths OF A SECOND OR LESS.

TRAINS SUBWAY AND METRO SYSTEMS

IN THE MONTREAL METRO ALONE THERE ARE AT LEAST TWO OR
THREE INCIDENTS A YEAR OF SUICIDES ACCIDENTAL FALLS AND
DELIBERATE MURDER ATTEMPTS CAUSING SOMEONE TO FALL IN THE
PATH OF AN ONCOMING TRAIN.

ABOVE THE TRACKS WILL BE THE TRIGGERING DEVICE THAT WILL DEPLOY
AN EXTERNAL AIRBAG IN 2110ths OF A SECOND.
ONCE A FALLING BODY BREAKS THE LASER BEAMS THE AIRBAGS WILL
DEPLOY AND THE BRAKES WILL AUTOMATICALLY APPLY.
THE BODY WILL BE TOSSED FORWARD TILL THE TRAIN CAN COME TO
A STOP.

Claims

Claims Page This Invention relates to External Airbags that will inflate outside of a vehicle offering protection to both the people inside the vehicle and Pedestrians or other objects and vehicles outside the object vehicle.
The inventive idea for this invention is that children and frail adults will not be dependent entirely on the workings of the interior Airbag which has a tendency to hurt or even kill the frail user by the great force of the split second opening.
Claim 1: The External Airbag will prevent accidental killing of Pedestrians or drivers by manual or laser controlled deployment of the Airbag shown visually on pages 3,5,7,10 14,15,16.
Claim 2: Vehicle to Vehicle collisions are prevented by means of External Airbags that are deployed manually or automatically as shown in diagrams on pages 3,7,10,14.15,16.
Claim 3: Snowmobiles will be prevented from sinking through thin ice covered lakes by the inclusion of inflating external airbags as shown in diagram 18 and would give increased protection to the riders if engulfed in an avalanche.
Claim 4: External Airbags attached to the front of Metro trains and activated either manually by the driver or by the severence of a laser beam will prevent a body that has fallen in the path of the train from crushing the body but the large external Airbag will push the body forward a required distance till the train can come to a halt as shown in diagram 20.
Claim 5: Stopping collisions in advance by computer controlled laser beams that determine if the object is moving in relative motion and not hostile or moving in an inescapable speed towards the object at collision force which will activate and deploy External Airbags and prevent a collision as shown in diagrams on pages 7 and 10.
