Dictionary.com defines a passive restraint as “a safety device, as an air bag or special seat belt, that is activated automatically to protect an automobile passenger at the moment of impact when a collision occurs.” Passive restraints are not limited to vehicular safety. Other passive restraint systems prevent falls, such as guardrails and fences. A guardrail around the viewing area of a canyon is an example of a passive restraint as it is a barrier between a potential danger and humans.

Additionally, because a person would have to cross a protective barrier for an injury to take place, passive restraints systems discourage the filing of frivolous lawsuits.
