Purpose and function of the head air curtain

The presented head air curtain is a component of the side safety system, mounted in the headliner area on the left side of the vehicle. Its task is to mitigate the effects of a side impact and potential contact of the head and upper torso with the window or body pillars. Using an original BMW solution ensures proper cooperation with crash sensors, the SRS control unit, and other airbags in the vehicle.

Compatibility and OEM standard

The curtain has been designed specifically for the roof structure and side body zone of the BMW 3 Series E90, including the LCI version. This means it fits factory mounting points, has the correct routing geometry along the headliner, and complies with activation parameters specified by the manufacturer. As an OEM-class part, it maintains factory standards for material quality, airtightness, and resistance to operating conditions inside the cabin.

Vehicle placement and installation aspects

The component is intended for installation on the left side of the vehicle, which is crucial for the proper operation of the safety system. Correct placement on the vehicle facilitates service work – mounting points, wiring harness routing, and the method of integration with the headliner are consistent with the original BMW design. As a result, the curtain can be installed in a way that replicates the original configuration, without the need for interior structural modifications.

Condition, origin, and benefits of choosing a used part

The head air curtain is a used original BMW component, which allows for combining controlled repair costs with the preservation of factory specifications. Compared to aftermarket replacements, the original OEM part ensures consistency with the vehicle's electronic system and predictable behavior during activation. This is a particularly beneficial solution for post-accident repairs, where both safety and compliance with the manufacturer's technical documentation are paramount.

OEM safety and additional information
