Construction and Technical Characteristics of the Driver Airbag

The driver airbag in the Mercedes Vito W639 is an integral part of the safety system, working in conjunction with collision sensors and the SRS control unit. Its construction includes the airbag module with a gas generator and a housing designed for steering wheel installation.

This solution has been developed by the vehicle manufacturer, ensuring:

• maintenance of the inflation characteristics intended by the engineers,
• appropriate deployment geometry of the airbag relative to the driver's torso and head,
• cohesion with other safety system components within the interior.

Using an original airbag module helps maintain compliance with the vehicle's original design specifications, which is important for both safety and subsequent technical inspections.

Condition, Verification, and Installation Aspects

The driver airbag offered in this listing is a used component, sourced from a dismantled vehicle. Before being offered for sale, this type of component is routinely verified for:

• absence of deployment marks and mechanical damage to the housing,
• condition of electrical connectors and mounting points,
• compatibility with the intended dashboard generation.

Installation by a qualified service center is recommended, adhering to safety procedures for SRS systems (disconnecting power, correct sequence for steering wheel and airbag module removal and installation). This approach minimizes the risk of errors and ensures proper interaction with the vehicle's electronics.

Benefits of Using an Original Airbag

Choosing an original driver airbag for the Mercedes Vito W639 offers a range of practical benefits:
