Vehicle Application and Placement

The presented bracket is a structural element responsible for mounting the rear seat on the left side of the vehicle. Its placement, specified as rear – left side, means the part works with the factory mounting points in the floor and seat frame, ensuring proper guidance and support for the passenger seat.

This solution is particularly important in vehicles used daily, where the seat is subjected to cyclical loads during entry, exit, and driving over uneven surfaces. A properly selected bracket reduces unwanted play and minimizes the risk of incorrect seat positioning.

The bracket is designed as a component compliant with BMW's factory specifications, which translates to precise fitment to the seat structure and mounting points in the body. The mounting holes, shape, and profile of the bracket are adapted to the standard solutions used in BMW E46 and BMW X3 E83 models, facilitating installation without the need for modifications.

As part of the mounting and structural category, the bracket is responsible for:

• maintaining the correct position of the rear seat on the left side,
• stable transfer of loads from the seat to the body,
• preserving the correct geometry of the seating system in the cabin.

Product Condition and Practical Application

The offered bracket is a used item, which means it comes from a vehicle disassembly and has been verified for its suitability for further use. This type of OEM part retains its original construction and mounting parameters, making it an attractive alternative to aftermarket replacements that require fitting or modification.

Replacing the rear seat mounting bracket is recommended in situations where:

• mechanical damage to the mounting element has been identified,
• noticeable play in the rear left seat has occurred,
• post-accident repair or repair after intensive interior use is necessary.
