What is the principle behind seatbelt locking?

[BradleyRose]

The principle of seatbelt locking involves the retractor, which connects to the seatbelt via an internal spool. An internal spring provides reverse rotational torque to the spool. Below are detailed explanations about car seatbelts: 1. Ensuring passenger safety: Car seatbelts play a crucial role in protecting passengers, especially on highways where rear passengers are required to wear them. A seatbelt buckle clip is a device that can be inserted into the seatbelt socket, preventing the seatbelt alarm from sounding even when the driver is not wearing the seatbelt. 2. Enhancing driving safety: Seatbelts are the primary safeguard for driver safety, representing an active form of protection. Even at relatively low speeds, a collision or sudden braking can generate enough inertia to cause the driver and passengers to lose control of their bodies, potentially leading to injuries from impact with hard components like the steering wheel or windshield.
