Purpose and fitment for BMW seats

The presented airbag is a component from the Seats and benches group, designed to work within the structure of the front passenger seat. Its design is adapted to the standard mounts in the BMW 3 Series E90/E91 generation seat, which allows for maintaining factory wiring routing, proper positioning of the module in the seat or backrest foam, and correct cooperation with SRS sensors and the control unit.

The placement in the front-right zone allows for precise reproduction of the original passive safety configuration, without the need to modify the seat structure or electrical installation. As a result, the installation can be carried out in an orderly manner, in compliance with the vehicle manufacturer's standards.

Technical and functional characteristics

The airbag has been designed as an integral part of the BMW airbag system, working with the factory controller and collision sensors. The use of a dedicated seat module allows for:

• maintaining the appropriate deployment sequence in the event of a collision,
• preserving the inflation characteristics intended by the manufacturer,
• proper communication with vehicle electronics and onboard diagnostics.

The black color facilitates aesthetic integration with the interior typical of E90/E91 models, especially in configurations with dark upholstery. The module is intended for installation inside the seat, so its color promotes discreet cable routing and maintains a consistent appearance of structural elements.

Condition, origin, and practical application

The item comes from dismantling and is offered as a used original BMW component, which means it retains factory geometry, connectors, and compatibility with the vehicle's installation. In practice, this translates into:

• the ability to restore SRS system operation after deployment or damage to the previous module,
• reduced risk of fitment issues compared to universal replacements,
• easier diagnostics in case of safety system checks.

Due to the nature of the safety component, installation should be carried out by a person with experience in working with SRS systems, while observing procedures for disconnecting power and handling pyrotechnic connectors. A correctly installed seat airbag restores the integrity of the passenger protection system in the front right part of the cabin.

Interior integration and user comfort

The seat airbag works with the seat and backrest structure without negatively affecting ergonomics or seating comfort. Thanks to the fitment for the specific generation of BMW E90/E91 seats, the following are maintained:

• stability of the foam and upholstery in the installation area,
• proper operation of seat adjustment mechanisms,
• visual consistency of the interior, without unnatural creases or deformations.

This solution is particularly important for post-accident repairs, where the goal is not only to restore safety but also to maintain the comfort and aesthetics of the cabin at a level consistent with the manufacturer's specifications.
