Intended Use and Vehicle Placement

The presented seat belt is designed for operation on the front left side of the cabin, which is the driver's area in a typical European configuration. It is responsible for stably holding the occupant's position during driving, braking, and in emergency situations, working in conjunction with other passive safety system components.

Dedicated placement on the vehicle means that the mounting geometry, belt length, and retractor mechanism are adapted to the specific installation position, which facilitates installation and reduces the risk of malfunction.

Technical and Functional Characteristics

The seat belt offered here comes from the family of original BMW solutions, which translates to compatibility with factory mounting points and system operating parameters. The retractor mechanism is designed to ensure:

• smooth belt extension and retraction under typical driving conditions,
• increased resistance and locking during sudden acceleration or braking,
• stable belt positioning relative to the seat and body pillar.

By maintaining factory parameters, the belt works with the seat structure, airbags, and body crumple zones, which is important for predictable vehicle behavior in critical situations.

Benefits of Using an Original BMW Seat Belt

Choosing Seat Belts and Parts from BMW allows for maintaining the integrity of the entire safety system. Key advantages include:

• factory fitment to the body and seat structure,
• preservation of the manufacturer's designed operating characteristics of the retractor mechanism,
• no need for modifications to mountings or belt routing,
• compatibility with other OEM components in the vehicle.

This solution is particularly important for safety-critical components, where the precision of operation and predictability of the system's response directly impact user protection.

Item Condition and Practical Application

The offered seat belt is a used part, allowing for economical restoration of the system's functionality while maintaining the original BMW construction. This is a good solution in situations where replacement is necessary after system deployment, collision, or wear and tear, and compliance with factory specifications is a priority.

Before installation, standard verification of the retractor mechanism's proper operation and inspection of the vehicle's mounting points are recommended to ensure correct integration with the existing system.
