Purpose and Function of the Seat Belt Height Adjuster
The front seat belt height adjuster, mounted on the left or right side, is responsible for smoothly changing the position of the upper seat belt anchor point relative to the car body pillar. Thanks to this:
- it correctly guides the belt across the user's collarbone and chest,
- it reduces the risk of the belt slipping off the shoulder during sudden braking,
- it improves driving comfort for drivers and passengers of different heights,
- it supports the effectiveness of the vehicle's passive safety system.
This component is particularly important in premium cars like Audi, where consistent operation of all safety and ergonomics-related sub-assemblies is expected.
Construction and Fit for Audi
The Front Seat Belt Height Adjuster has been designed as part of the Audi body system, maintaining factory mounting points and operating geometry. This means:
- precise fit with the front pillar without the need for bodywork modifications,
- compatibility with original seat belts used in the specific model,
- preservation of the factory belt routing geometry, in line with the designers' intentions.
Such a fit is crucial for the seat belt system to function as designed by the manufacturer, and for the forces acting on the user's body to be distributed predictably.
Vehicle Placement and Installation Aspects
The presented adjuster is intended for mounting on the front cabin axis, on the left or right side. In practice, this means it can be used on both the driver's and front passenger's side, depending on the body configuration and equipment version.
When installing, pay attention to:
- correct seating in the pillar guides to ensure smooth operation of the adjustment mechanism,
- maintaining the correct order of interior trim installation to prevent unwanted tension and squeaks,
- checking the operation of locks and latches after installation is complete to ensure stable height adjustment.
Professional installation allows for full utilization of the component's functionality and maintains the high standard of interior finish characteristic of Audi.
