Forensic analysis of seat occupancy sensor data – Forensic documentation of vehicle seat occupancy status

Seat occupancy sensors detect whether a seat is occupied and the approximate weight of the occupant, and are primarily used to control airbag and seatbelt warning systems. Certain control units log the occupancy status on an event-by-event basis.

Enquire without obligation

This data may be relevant for reconstructing the number of occupants and their seating positions at the time of an incident.

Our services

We analyse the available seat occupancy data from the relevant control units and document the occupancy status of individual seats during the study period.

Typical areas of application

Reconstruction of the number of passengers at the time of the accident
Clarification of the seating position of individual passengers
Supplementing seatbelt buckle and airbag data analyses
Investigation of hit-and-run incidents involving vehicles with multiple occupants
Judicial and non-judicial expert reports
Assessment of personal injury under insurance law

How a seat occupancy sensor analysis works

Once the relevant control units have been backed up, the available occupancy data is extracted and compared with seatbelt and airbag data for the relevant period.

Why is seat occupancy sensor analysis relevant in a forensic context?

Determining which seats were occupied at the time of the accident may be important for establishing the causes of injuries and who is responsible.

Even in the case of a hit-and-run involving several passengers, the documented seating arrangement can provide additional clues.

Frequently Asked Questions

Is seat occupancy logged on a permanent basis?+
As a rule, only short-term, event-based storage takes place; this is assessed on a case-by-case basis from a technical perspective.
Can a person’s exact weight be determined from the sensor data?+
The sensors generally provide only broad categories or threshold values, not exact weight figures.
Are the rear seats monitored as well?+
This depends on the specific vehicle specifications and is assessed on a case-by-case basis.
