Purpose/Function
An intrusion-minimizing brake pedal has been adopted to the brake pedal to provide for a measure of safety in the event of an accident.
The intrusion-minimizing brake pedal mechanism reduces impact to the lower extremities of the driver by minimizing the amount of rearward brake pedal thrust in a frontal collision.
Construction
The intrusion minimizing 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.

Intrusion-minimizing 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.

Seat belts help to decrease the possibility of severe injury during accidents
and sudden stops. Mazda recommends that the driver and all passengers always wear
seat belts.
All of the seat belt retractors are designed to keep the lap/shoulder belts out
of the way when not in use.

Brake System/ABS Warning Light
Purpose/Function
The brake system/ABS warning light is built into the instrument cluster.
If a malfunction is detected in the system with the parking brake released,
the warning light illuminates to notify the driver.

Electric Variable Valve Timing Actuator
Purpose, Function
The electric variable valve timing actuator changes the phases of the intake
camshaft relative to the crankshaft. As a result, the open/close period of the
intake valve is changed, optimized valve timing in accordance with driving conditions
is realized, output is i ...
