Abstract

PURPOSE: To improve energy absorption efficiency and reliability by absorbing sequentially the impact energy of a collision by its dampening operations step by step, and by causing its operational mode to change according to the magnitude of impact energy.
CONSTITUTION: When impact force P acts on a bumper 5 by a collision, a damper tank 9 is elastically deformed and functions as a pneumatic spring and performs the first dampening by absorbing impact energy. When the energy cannot be absorbed by the said No.1 dampening, a pressure switch 14 is turned on by the air pressure of the tank 9 and it causes a motive power system such as an engine, etc. to turn off and causes an emergency brake to operate. Simultaneously, a valve 15 opens and the gas of the tank 9 is sent to an emergency bag 13 through a pipe route 12 and the bag 13 is inflated to perform the second dampening and further the bag 13 performs the third dampening gas a dampening body. Next, by the collision of a driver or passenger to the bag 13, its pressure rises and opens a valve 19 and the pressurized gas escapes through a throttle valve 20 and the bag 13 performs the fourth dampening.
