Abstract

The invention provides a protective air bag in a bumper of a locomotive car, which aims to solve the problem that the existing air bag in a car does not play a role in protecting the cars and passengers crashed by the cars in car crash. The protective air bag has the key points as follows: a main air bag, an auxiliary air bag and an arm protecting air bag are arranged between the locomotive car bumper and the car body; after the power supply of gas generators is switched on by a driver, two gas generators are used for inflating the main air bag, the auxiliary air bag and the arm protecting air bag respectively, the main air bag, the auxiliary air bag and the arm protecting air bag rush out an air bag bin one after another, so that air bag protection is formed at the front side and the rear side of the locomotive car. thus rigid crash of the original cars is changed into flexible crash, and the sufferers and cars can be protected.
