This invention describes (i) an occupant classification, (ii) a baby seat detection, and (iii) an integrated occupant sensory system. The main goal of the invention is to provide the vehicle's restraint device(s) with enough information about the vehicle's occupant as to take the most appropriate actions necessary for the safety of the occupant. This invention (or some sub-modules of it) does not have to be restricted to the use in automotive restraint systems as it may be used in several other applications as well.

Integrated occupant sensory system

This invention describes an occupant size and weight detection device consisting of a combination of force/load sensors (), a head position sensor (), a multidirectional acceleration sensor (), and a seat position sensor () used to determine the weight of an occupant based on weight distribution, body angle and foot position. The goal of the invention is to determine the weight of an occupant who is sitting in the front seat of a vehicle that is subjected to the dynamic forces resulting from the vehicle moving. This technology can be used in applications such as automotive occupant weight and position sensing for use with safety devices such as airbags.

Vehicle occupant weight estimation apparatus

A child seat detection system determines the presence of an infant seat and can distinguish between a forward-facing infant seat and a rearward-facing infant seat. The system determines the weight on a vehicle seat and compares the weight on the vehicle seat to a rear-facing infant seat maximum. If the weight on the vehicle seat exceeds the rear-facing infant seat maximum, the system determines whether a forward-facing infant seat is on the seat. If the weight on the vehicle seat does not exceed the rear-facing infant seat maximum, then the system determines whether a rear-facing infant seat is on the seat.
