Seat Belt Pretensioner Purpose and Function
The seat belt pretensioner is responsible for rapidly tightening the belt against the driver's body when the safety system is activated. This limits uncontrolled body movement during a collision and works in conjunction with airbags, enhancing the overall level of protection within the cabin.
The presented pretensioner is designed for installation on the front left side of the vehicle, meaning it works in tandem with the driver's seat belt in the BMW 7 Series E65. A correctly selected and functional component is crucial for maintaining the original safety parameters of the BMW's construction.
Compatibility and Technical Parameters in Practice
As part of the Seat Belts and Parts group, the pretensioner works with the factory seat mounting, belt buckle, and the safety system control unit. Proper placement on the vehicle (front, left side) ensures correct belt routing and the proper functioning of the tensioning mechanism.
The component has a dedicated OEM part number and interchangeable numbers, which facilitates verification of compatibility with a specific BMW E65 configuration. Before purchasing, it is advisable to compare the designations with your vehicle's data to ensure the pretensioner will work correctly with the existing belt and safety system controller.
