Occupant Restraint Systems are safety features in vehicles designed to protect passengers during a crash. These systems include seat belts, airbags, and child safety seats, which work together to minimize injury by securing occupants in their seats and absorbing impact forces. Seat belts are the primary component, preventing occupants from being thrown forward. Airbags deploy rapidly to cushion the impact, while child safety seats provide additional protection for younger passengers. Proper use of these systems is crucial for enhancing safety and reducing the risk of serious injury in accidents.
