Air bag system for an automobile

Claim 1

An air bag system installed in a vehicle for protecting vehicles, passengers, roadside objects, and pedestrians from being damaged and injured at a collision, the air bag system comprising: means for using an external detection system for obtaining information relating to a roadway obstacle, a roadway vehicle and roadway conditions; means for using an internal detection system installed inside of the roadway vehicle for obtaining information on passengers' conditions inside of the roadway vehicle; means for using a wireless system for obtaining required information to function the air bag system; means for a computer processing unit (hereinafter referred to as CPU) installed in the roadway vehicle to process information obtained by said external detection system, said internal detection system, and said wireless system based on information inputted in said CPU, said CPU having a means for calculating of a criterion for inflation of an external air bag, calculating inflation size and shape of the external air bag, and calculating absorption quantity of the external air bag, and said CPU having a means for calculating a criterion for inflation of an internal air bag and calculating absorption quantity of the internal air bag; means for using at least one external air bag inflation device installed in the roadway vehicle, said at least one external air bag inflation device having an external air bag installed therein for inflating said external air bag prior to a collision over an external portion of the roadway vehicle in an imminent situation to reduce collision damage to the vehicle and obstacles, injury to passengers and pedestrians; means for using at least one internal air bag inflation device installed in the roadway vehicle, said at least one internal air bag inflation device having an internal air bag installed therein for inflating said internal air bag toward the passengers of the roadway vehicle prior to a collision in an imminent situation to reduce injury to the passengers; means for deciding an inflation size of each external and internal air bag according to a roller connected to a motor controlled by said CPU installed in an air bag inflation device in the vehicle; said external air bag inflation device and said internal air bag inflation device comprising: an air bag, one end of which being attached to a roller for enabling said roller to release said air bag from a retracted condition by the roller rotating in a first direction; a roller rotatably positioned inside of said air bag inflation device for enabling the roller to rotate for controlling inflation size of said air bag; a motor attached to the roller for rotatably driving the roller, the motor being rotatable in a second direction for opposing rotation of the roller, by which the releasing of said air bag is stopped at required inflation size to hold the inflation of said air bag; a first roller sensor attached to an inside surface of said air bag inflation device surrounding the roller to help detect the number of rotations of said roller; a second roller sensor attached to an outside surface of said roller for providing a means by which number of rotations of the roller is detected; a first absorption device connected to an external layer of said air bag to provide a primary means for relieving a collision impact intensity imposed on said air bag in an inflated shape; a second absorption device connected to an internal layer of said air bag to provide a secondary means for relieving a collision impact intensity imposed on said air bag in an inflated shape; and a photoelectron system used for supplying energy to air bag system, which is currently used in the industries.

Claim 43

The system recited in 37 , wherein said CPU calculates a criterion for inflation of said internal air bag in an applicable zone of said roadway vehicle based on inflation size and shape of said external air bag in an applicable zone of said roadway obstacle according to accord.

Claim 44

The system recited in 37 , wherein said CPU calculates a criterion for inflation of said internal air bag in an applicable zone of said roadway vehicle based on inflation size and shape of said external air bag in an applicable zone of said roadway obstacle according to accord.
