The seat belt can be stretched and retracted - when the seat belt is not tensioned, the body can easily lean forward. But when the vehicle hits and the human body leans forward rapidly, the cam-lock Quick release racing harness will suddenly tighten and fasten the human body tightly.

There is a card wheel in the traditional seat belt device. If the seat belt is pulled quickly, for example, in the event of a car accident, the inner card will be pulled out by centrifugal force due to the rapid rotation of the seat belt roller, and the seat belt will be quickly locked. Secure the person in the seat to the chair. When the impact peak has passed, or when the person is already protected by the airbag, the seat belt is relaxed so as not to crush the person's ribs. From the above series of actions to achieve the purpose of ensuring the safety of drivers and passengers.
The cam-lock Quick release racing harness comes with pre-tensioners and pull limiters and more. You can pull this seat belt fast and it will lock because there is an inertia block inside the seat belt. When the speed reaches a certain acceleration greater than or equal to 2.0G, a reed in the inertia block moves down with the inertial force, making the inner ratchet catch and the inner gear locked. This kind of lock we call drive sensitive. There is also a kind of vehicle motion sensitivity, which locks the car when it goes up and down or rolls over.
Why the cam-lock Quick release racing harness can be pulled at a slow speed, but locked when pulled at a fast speed? Principle, this part is mainly related to the buckle structure of the seat belt.
