Occupants are being prepared for an accident or emergency brake by triggering a reversible electro-mechanical belt tensioner.

Occupant Safety Monitor
The Occupant Safety Monitor acts as a permanent monitor of the environment in the vehicle in terms of safety. The information of several suitable sensors (e.g. camera, radar, position/weight sensor data from sensor systems, etc.) results in a complex sensor fusion model. By means of this model optimum deployment strategies for the restraint systems are permanently being calculated - individually for each occupant.
It gives important information to the deployment strategy of restraint systems and is suitable for new restraint concepts. The monitor detects whether occupants are too close or too far to the airbag (Lean Backward Warning, Lean Forward Warning). Body structure including the direction of the head also is being detected.
