Purpose/Function
• 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.
Construction
• 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

Operation
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.am3zzn00006768
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.
