Is there any vehicle safety device that can replace the seat belt?
Active and passive safety
Explanation
**Safety devices** in a vehicle, such as the **seat belt**, **airbag**, and **headrest**, are designed to **function complementarily** and not to replace each other.
- The **seat belt** is crucial for protecting occupants in the event of an accident, preventing them from moving from their seats or being ejected from the vehicle. Its correct use can double the chances of surviving an accident.
- The **airbag** is another passive safety element that activates automatically in the event of a collision, but it is designed to work together with the seat belt, not to replace it.
- The **rear seats** are not safety devices by themselves; they also require the use of seat belts to protect passengers.
Therefore, no device can replace the seat belt; all must be used together to maximize protection.
