The external force destroyed structure in the vehicle hydraulic pressure generator

摘要

PROBLEM TO BE SOLVED: To prevent a pedal and the like from colliding with legs of a driver by a vehicle collision by arranging an air bag for swelling from the vehicle front direction by external force and bending a hydraulic pressure generator sideways in the vicinity of the hydraulic pressure generator composed of a brake booster and a master cylinder. ;SOLUTION: When an impact detecting sensor 7 is turned on since excessive external force acts by a collision of a car body front part, an air bag 6 is driven, and the air bag 6 instantly swells toward a cylinder body 10a of a hydraulic master cylinder 10 and a front half part of a reservoir 14, so that a car body leftward directional load is applied to the cylinder body 10a and the reservoir 14, and a hydraulic pressure generator 4 is bent in the car body leftward direction from a connecting point between the hydraulic master cylinder 10 and a booster 9 and a connecting point between the booster 9 and a dash panel 3 or the other fragile place. Thus, thrust-back force does not act on a push rod 9c and a brake pedal 5 to avoid an impactive collision of the pedal 5 with legs of a driver.;COPYRIGHT: (C)2000,JPO
