FRONT STRUCTURE OF BUS
Document Type and Number:
Japanese Patent JP3426501
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To reduce the weight of a bus while restraining the displacement to the frontside of a floor board easily by constituting so that the floor board is folded from its brittle part to the upperside when the displacement occurs to the vehicular frontside of the floor board.
SOLUTION: In this bus, a reinforcement member 1 is extended from a front end to a rearside and also a rear portion 2 is arranged highly by the bending to the upperside. Plural notches 7 with a nearly triangle section extending to the car width direction are formed on the lower surface of the floor board 5 of the upperside of the reinforcement member rear portion 2 and the vehicular rearside from the reinforcement member 1. When the floor board 5 with a big inertia is displaced to the vehicular frontside when the front collision occurs to the bus, its front end 6 is folded so as to be swelled upward, as it is fixed to the upper surface of the reinforcement member rear portion 2 and the displacement to the vehicular frontside is restrained. As this result, it can be restrained easily that the entire floor board 5 is displaced to the vehicular frontside linearly. Thus, the support structure of entire floor board can be simplified and the weight of the car body can be reduced.
