• An anti-intrusion brake pedal has been adopted to the brake pedal to provide for a measure of safety in the event of an accident.
• The anti-intrusion brake pedal mechanism reduces the amount of rearward brake pedal thrust in a frontal collision and the impact to the lower extremities of the driver.


• The anti-intrusion brake pedal mechanism is structured on the brake pedal and consists of the following parts.
― Pedal arm
― Lever
― Pin A
― Pin B
― Pin C
― Bracket



During normal braking

• When the brake pedal is depressed, the pedal arm rotates at the pin A fulcrum point, and the pedal depression force is transmitted to the fork of the power brake unit.
• This pedal depression force pushes in the fork to operate the brakes.


During anti-intrusion operation

• In a frontal collision, the brake pedal is forced rearward by the movement of the dashboard.
• In response to this, force in the direction of X is applied to the brake pedal lever because the dashboard member and brake pedal lever interfere.
• With the addition of force in the direction of X, pin C releases from the lever, and the lever rotates around the pin B fulcrum point.
• When the lever rotates, it obstructs pin A at the fulcrum point of the pedal arm.
• If the pedal rotates further, pin A separates from the bracket (notch), and the pedal is freed.
• By freeing the pedal arm, the force applied to the lower extremities is reduced.
