[VanAdeline]

Volvo XC90's seat belt can retract automatically. Here is more information about Volvo XC90: 1. All vehicle seat belts are designed to retract automatically after use. The seat belt is connected to a retractor: the core component of the retractor is a spool, which is connected to one end of the seat belt. 2. The internal structure of the seat belt device varies in complexity depending on the vehicle's grade. More advanced seat belts are equipped with pre-tensioners and force limiters. The pre-tensioners can be rack-type, cable-type, or ball-type, and some pre-tensioners also use electric motors for retraction. 3. The principle of the seat belt buckle: when inserted and locked, pressing the buckle releases it. The seat belt buckle is a connecting device that can restrain the occupant within the seat belt while allowing quick release. The function of the buckle is to engage or disengage the seat belt. There is a micro switch inside the buckle. When the tongue is not inserted, the switch closes, which can activate the seat belt warning light and send a signal to the control unit. When the vehicle reaches a certain speed, it triggers light and voice alarms to remind the driver and passengers to fasten their seat belts.
