Where must the seat belt chest strap pass to be effective and safe?

Question

DentroTest · Accepted Answer

The chest or diagonal strap must be positioned strictly between the shoulder and the neck, resting on the collarbone (clavicle) and crossing the center of the chest. Detailed explanation: The purpose of the seat belt is to restrain the body by applying force to its strongest parts (the bones) rather than soft tissues. Correct: Over the clavicle and sternum. These bones are strong and can withstand deceleration forces. Incorrect (Neck): If the strap touches the neck, a sudden stop could cause severe cuts, burns, or strangulation. Incorrect (Under arm/Behind back): This renders the system useless. The torso would remain unrestrained, causing the driver to hit the steering wheel or windshield.
