The **pressure clips** on seat belts are used to **provide more slack** and prevent the belt from being too tight. This is important because the belt should be well adjusted to the body, but not so tight that it prevents the passenger from moving comfortably.

- A well-adjusted belt should allow you to move easily, without being too loose or too tight.
- The **chest strap** should pass correctly between the shoulder and the neck, and the **lap strap** should be over the hip bones.
- The pressure clips help maintain this proper adjustment, ensuring that the belt fulfills its protective function without causing discomfort.

Therefore, the use of pressure clips is essential to maintain the balance between safety and comfort when using the seat belt.
