Purpose and vehicle placement

The presented seat belt handover arm is designed for installation in the front area on the left side, i.e., the driver's side. The component works with the factory seat belt mechanism, extending and presenting the belt within the user's reach after opening the door or taking a seat, which significantly improves the convenience of using the seat belt in a coupé body style. Thanks to its dedicated placement within the seat structure and the side of the cabin, the handover arm maintains the correct belt routing geometry, which helps keep the belt in the proper position on the driver's body. This solution reduces the risk of the belt twisting and facilitates smooth retraction after the drive is finished.

Technical and functional characteristics

The handover arm was designed by BMW as a component of the passive safety system, in compliance with the manufacturer's rigorous standards. The design ensures:

• stable seat belt guidance along the seat axis,
• controlled extension of the handover arm towards the driver,
• proper cooperation with the factory retractor mechanism,
• maintenance of appropriate rigidity and resistance to operational loads. As an original part from the Seat belts and parts group, the handover arm is structurally matched to the interior geometry of the BMW E92, which translates into a proper fit with the upholstery and trim elements. The lack of need for mounting modifications facilitates trouble-free installation in place of the factory component.

Condition, origin, and benefits of use

The offered seat belt handover arm is a used component, which allows for an economical repair of the safety system while maintaining the manufacturer's original specifications. Using a part sourced from a BMW dismantling allows for the maintenance of the vehicle's technical consistency, without the risk of mismatching characteristic of universal replacements. Choosing an original BMW handover arm brings a number of practical benefits:

• preservation of the factory functionality of the belt handover system,
• secure fit to the seat and side interior trim,
• reduced installation time due to compatibility with original mounting points,
• maintenance of a consistent passive safety standard in the vehicle.

Compatibility and installation aspects

The handover arm was developed specifically for the BMW E92 body, which means that its geometry, arm length, and belt routing method are adapted to the door, pillar, and seat construction of this model. Installation involves replacing the damaged or non-functional factory component, using existing mounting points and original connections. To maintain full functionality, it is recommended that installation be performed by a person with experience in working with safety system components, taking into account proper belt routing and checking the free movement of the handover arm. A properly installed handover arm restores comfortable belt presentation for the driver and supports safe use of the system.
