METHOD AND DEVICE FOR DETECTING SEAT OCCUPANCY BY MEANS OF A VIDEO SENSOR SYSTEM AND FOOT ROOM SENSOR SYSTEM

摘要

The method involves detecting the head height of a person on a passenger seat (1) with a video sensor system (4) and using footwell sensors (5, 6) to detect whether the person has one or both feet in contact with the floor in front of the passenger seat. The person is detected as a child if the head height is determined to be below a defined threshold with no foot contact with the floor detected, and in this case airbag activation is inhibited in the event of a collision. An independent claim is included for an arrangement for detecting seat occupancy.
