DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a shock absorber for a car, and more specifically relates to a shock absorber for a car in which external portions of the car that may be contacted from the outside such as the roof, the doors and the front and rear side panels, as well as the front and rear bumpers, are formed with air sheets filled with compressed air or helium gas, so that a shock inflicted from outside at the time of a collision or overturn of the car can remarkably be absorbed and relieved.
BACKGROUND OF THE RELATED ART
Generally in conventional cars, as is well known, the front and rear bumpers using relief effect of spring or oil pressure are mounted at both the front and rear of a car for absorbing or relieving a shock at the time of collision of the car. However, although the conventional bumpers may be effective in event of a slight collision, they are considerably insufficient for protecting the occupants or the car body in case of a collision during high speed driving. Further, in case that the car is hit from a side or falls or is overturned, since a separate apparatus for relieving or absorbing the shock is not provided in the prior art, not only is the body of a car easily damaged, but also the occupants get hurt and can even be killed by the shock.
SUMMARY OF THE INVENTION
Therefore, a primary object of the present invention is to provide a shock absorber for a car in which the safety of the occupants is secured as far as possible by allowing relief of shock inflicted to a car by absorbing the shock, even in the case of overturn due to the collision from a side, a fall, or front collision.
Another object of the present invention is to provide a shock absrober for a car in which a shock is absorbed in a step manner by constructing the front and rear bumpers with a three stage structure for low, medium and high pressure shoch absorption, so that the shock absorption effect is remarkably enhanced.
A further object of the present invention is to provide a shock absorber for a car in which the gas circulation tubes are interconnected among the front and rear bumpers and the right and left side in case that the car is hit from the front or rear and from the right or left, thereby a puncture caused by an instantaneous shock is prevented and also the shock absorbing effect is enchanced due to the dispersion of the gas.
The present invention also aims to use a helium gas which is light in specific gravity and is non explosive in time of collision. The air sheet is filled with helium gas and is formed with a tube like shape so that, in case that a material of the air sheet is applied with a metal plate having high strength, the shock can be absorbed.
The present invention also intends to provide a shock absorber for a car in which almost the whole part of the external covering portion of a car is structured with the air sheets and thereby buoyancy occurs so that, in case the car falls into water, drowning of the occupants is prevented.
The present invention aims also to provide a shock absorber for a car in which a mechanical noise or the like of an engine is absorbed by the gas-filled air sheets.
In order to attain the above objects, the present invention is comprised of front and rear bumpers which are each made of a bumper member of low, medium and high pressure shock absorption filled with an air or gas of predetermined pressure and each having different thicknesses and gas capacity. An air sheet filled with a gas and conforming to the shape of and mounted to the front and rear side panels, an air sheet filled with a gas of predetermined pressure and conforming to the shape of and mounted to the doors of a car, and an air sheet filled with a gas of predetermined pressure conforming to the shape of the roof are provided. A longitudinal gas circulation tube is arranged longitudinally within the body of a car so that a front bumper member for the medium and high pressure shock absorption and a rear bumper member for the medium and high pressure shock absorption are inter
