Editing Seat belt (section)

* Manual lap belt with automatic motorized shoulder belt: When the door is opened, the shoulder belt moves from a fixed point near the seat back on a track mounted in the door frame of the car to a point at the other end of the track near the windshield. Once the door is closed and the car is started, the belt moves rearward along the track to its original position, thus securing the passenger. The lap belt must be fastened manually.
* Manual lap belt with automatic non-motorized shoulder belt: This system was used in American-market vehicles such as the [[Hyundai Excel]] and [[Volkswagen Jetta]]. The shoulder belt is fixed to the aft upper corner of the vehicle door and is not motorized. The lap belt must be fastened manually.
* Automatic shoulder and lap belts: This system was mainly used in General Motors vehicles, though it was also used on some [[Honda Civic]] hatchbacks and [[Nissan Sentra]] coupes. When the door is opened, the belts go from a fixed point in the middle of the car by the floor to the retractors on the door. Passengers must slide into the car under the belts. When the door closes, the seat belt retracts into the door. The belts have normal release buttons that are supposed to be used only in an emergency, but in practice are routinely used in the same manner as manual seat belt clasps. {{Citation needed |date=September 2010}} This system also found use by [[American Specialty Cars]] when they created the 1991-1994 [[convertible]] special edition of the [[Nissan 240SX]], a car that traditionally had a motorized shoulder belt.
