Purpose and function in the vehicle

The driver's knee airbag operates in the front zone of the vehicle, in the dashboard area, as an integral part of the airbag system. Its task is to limit the movement of the driver's legs towards the steering column and the lower part of the cockpit during sudden braking or a collision. The proper operation of this component contributes to:

• reducing the loads acting on the knees and femurs,
• stabilizing the driver's position in the seat at the moment other airbags deploy,
• a more even distribution of forces in the contact zone with the dashboard.

Thanks to a design developed for specific Mercedes models, the airbag works with factory collision sensors and the SRS controller, which allows for maintaining the consistency of the entire safety system.

Construction and integration with the dashboard

The presented knee airbag is a component intended for installation within the dashboard structure, in the front part of the vehicle. The housing and mounts are designed to:

• ensure stable seating in factory mounting points,
• maintain the correct geometry relative to the driver's knees,
• allow for the correct opening of the flap in the lower part of the cockpit upon activation.

Such a solution allows for maintaining the original interior line and proper fit with other dashboard elements, which is important both in terms of safety and ergonomics.

Operational characteristics

The offered knee airbag comes from the Dashboards group, which means it has been designed to work in the immediate vicinity of cockpit elements and the steering column. As a used part, it provides a solution for technically correct SRS system repair after a collision or the replacement of a damaged module without the need for expensive, new components. When selecting the element, it is crucial to consider:

• compatibility with the specific body generation and equipment version,
• compliance with the factory airbag controller,
• maintaining the correct placement in the front zone of the vehicle.

A set configured in this way allows for restoring the full functionality of the safety system in Mercedes cars, while simultaneously maintaining consistency with the original interior design.

Safety, installation, and application

During the installation of the driver's knee airbag, it is crucial to follow service procedures regarding SRS systems, including proper power disconnection and installation inspection. A correctly installed component:

• maintains the factory line of the lower part of the dashboard,
• ensures predictable behavior during activation,
• allows for proper cooperation with seat belts and other airbags.

Thanks to the original design intended for Mercedes models, the user gains a component matched to the interior geometry, which translates into predictable performance in emergency situations.
