INTRUSION-MINIMIZING BRAKE PEDAL

A6E691201020T01

Function

•

An intrusion-minimizing brake pedal construction, which minimizes the amount of backward thrust of the pedal,
has been adopted. It has been designed to soften the force of impact on the lower body of the driver.

Structure/operation

•

During a frontal collision, the backward thrust of the engine and other parts forces brake pedal bracket A
rearward and it separates from brake pedal bracket B.

•

The rearward movement of the brake pedal arm, connected at the fulcrum of brake pedal bracket A, is
prevented due to the stopper on brake pedal bracket B.

•

Due to this, the rearward movement of the brake pedal arm is suppressed by the displacement of brake pedal
bracket A.
