How should the seat belt be positioned?
Traffic safety: Transported persons and cargo
Explanation
To fasten the seat belt correctly, it is important that it is **adjusted to the body**, neither too tight nor too loose, and not twisted. This ensures that the belt fulfills its function of protecting in the event of an accident.
- **Shoulder strap**: It should pass over the collarbone, between the shoulder and the neck, and go down the center of the chest. If placed incorrectly, such as over the neck or a breast, it can cause serious injuries.
- **Lap belt**: It should be over the hip bones, below the stomach. Placing it above the stomach can cause serious internal injuries.
A well-adjusted belt prevents the **submarine effect**, which occurs when the body slides under the belt in an accident. This is prevented by ensuring the belt is well placed and adjusted, and maintaining a proper posture while driving.
The seat belt is crucial for protecting vehicle occupants, preventing them from moving from their seats or being ejected in the event of a sudden impact or rollover. Wearing it correctly significantly increases the chances of surviving an accident.
