Purpose and function of the backrest lock

The presented lock is responsible for mechanically locking the rear seat backrest on the left side. The component works with the seat structure, keeping the backrest in the desired position and allowing it to be unlocked when folding. A properly functioning lock eliminates play, unwanted noises from the rear of the body, and the risk of the backrest folding down spontaneously while driving.

Its placement in the rear of the vehicle on the left side allows for precise fitting to the factory mounting points in Mercedes compact class models from the W169 and W245 families, without the need for structural modifications.

Construction and fitment for Mercedes W169 / W245

The lock has been designed specifically for the geometry of the rear seat in Mercedes vehicles, which translates into:

• compatibility with the factory backrest folding mechanism,
• proper cooperation with latches and control cables,
• stable mounting within the seat structure.

Thanks to a design consistent with the manufacturer's solutions, the component maintains the correct position relative to the backrest hinges and seat belt mounting points, which is important for the comfort and safety of rear seat passengers.

Condition, application, and benefits of installation

The offered lock comes from the Other seat parts group and is a used component, making it an attractive cost-effective alternative to new parts while maintaining the original design.

• restore proper backrest locking on the left side,
• reduce rattles and play coming from the rear seat,
• increase the convenience of using the backrest folding function.
