For TITLE: TRANSPORTATION RIDERS WEB RESTRAIN SYSTEM

BACKGROUND— FIELD OF IMVENTION

The present invention relates to safety web restraint system for transportation riders during an accident. BACKGROUND— DESCRIPTION OF PRIOR ART

Seatbelts and air bags are the protection devices for the present day occupants of vehicles. Sadly, in America and all over the world thousands of fatalities still occur every day and many thousand more are seriously injured. While seatbelts do have some protection but are often ineffective at times either when occupants do not put them on for various reasons or they are worn incorrectly or yet the seatbelt system is malfunction. The most common malfunction of the seatbelt system is the shoulder belt, it does not seem to be able to lock up when needed most. Studies show that increased body movement during an accident results in more injuries. Seatbelts are not the solution, then the airbag was invented. One airbag first and then two and then four, there will be more airbags yet to come in the newer vehicles. Airbags help cushion the driver against the steering column during the initial crash and not much more, the human body still has to endure the violent thrust during the collision and that is the major cause of injuries. Airbags help during the initial crash impact but offer no help at all if there is any subsequent collision following. The cost to replace a spent airbag and repair the damages caused by the discharge of the airbag is huge.

Regrettably, seatbelts and airbags though are of some help to the occupants during an accident yet they do not at ail installed on the transportation vehicles with the exception of seatbelt on the aeroplane.

In L .S. patent 6502859 B l (2003) issued to Robert W. Svetlik describe a back 3 net enclosure to protect the occupants of a vehicle during an accident, but nothing illustrated about restraining occupants from thrust against the ceiling, front seat, side doors and back window during an accident collision.

In U.S. patent 5226672 issued to Royce H Husted ( 1993) is disclosing a web restraining about 1 /3 the body of a driver white holding the steering wheel near the bottom, chances are, during an accident , the lower portion of the body will thrust forward and the web might not be able to stop it. Some drivers prefer to put one or both their hands at the top of the steering wheel , then the web will only cover the head and neck and that can be detrimental, The cable pull mechanism does not show a tension release system, in that case the upper arms will be bound by the web so tight that the driver will not be able to continue control of the vehicle and worst yet get hurt by the pressure of the web system.

The present invention deploys a web with a headboard, reinforced at all the edges, knees, head and about mid section at the abdomen protects and restrains the occupant from head to feet during a collision impact. It is made of fire-proof, light weight, easy to pact and strong material which are already available in the market place, it can be stored in a tailor made case or be incorporated with the back rest of a seat The present invention showing a net and a case for easy demonstration. The restraining web can be released by unhooking one or more of the anchoring devices and can be reset again for future use, it is simple, effective , easy to make and low cost to build. OBJECTS OF THE INVENTION
