Accurate passenger classification for smart & safe airbag control

Download factsheet

Sensing whether someone occupies the passenger seat, but also who is in it is particularly important when it comes to airbags. Their main function is to enhance safety. However, if a clear distinction is not made between an adult occupant and a child, for instance, the airbag deployment could become a risk to the child/infant passenger, especially when in a rearward facing child seat.

Our BodySense occupant classification system helps avoid such risks. Thanks to its capacitive technology, it reliably suppresses the airbag in the presence of child seats on the front passenger seat and prevents risks of injuries. This intelligent sensor system safely makes the difference between the presence of an adult passenger for whom the airbag deployment is necessary in the event of an accident and a child restraint system, which requires the airbag to be switched off.

BodySense™ targets occupant classification in compliance with the U.S. National Highway & Traffic Safety Administration (NHTSA) Federal Motor Vehicle Safety Standard (FMVSS) regulation 208 and offers the perfect solution for low-risk deployment capable airbags. BodySense™ also covers the Euro NCAP incentives for automatic airbag disabling in the presence of rearward-facing child seats.

How BodySense works:
  • BodySense uses capacitive sensing technology for the vehicle’s front passenger seat
  • It provides the occupant classification information to the ECU, switching the airbag status accordingly
  • Thus, an accurate distinction between adult (airbag deployment in the event of an accident) or child/infant seat (airbag deactivation) is made
  • If the seat is unoccupied, the airbag system remains off

  2. Intuitive integration

    BodySense blends nicely in the A-surface of the car seat, above the seat heater, between foam and trim.
  3. Ready to use

    No need to calibrate or zero the sensing system at the vehicle assembly plant.
  4. Extra comfort

    Possibility to combine with seat heating by simple integration into the vehicle’s electrical structure. No changes required.
  5. Weather proof

    The performance is not affected by the climate or changing temperature conditions.
  6. Extra safety

    Supports seat belt reminder function.
