50 a senses that a vehicle seat immediately behind a vehicle seat is occupied for example seat i which is immediately behind seat h or seat g which is immediately behind seat f as shown in fig4 b the sensing system 50 50 a transmits a signal to a feature control system 16 indicating that the seat i is occupied the feature control system 16 then transmits a signal selectively restricting the travel of the back portion 52 a of the seat h such that the back portion 52 a will not be allowed to travel to the full down position e 2 this process is conducted passively based upon the sensed weight classification and or biomass fig5 is a flow chart that schematically illustrates yet another embodiment of the method of the present invention known vehicles have the ability to electronically sense when a vehicle is parked and locked by incorporating the passive weight classification and or biomass sensing strategies above in fig1 the vehicle can also determine if the vehicle is occupied when the vehicle is parked and locked and or if the vehicle becomes occupied subsequent to the vehicle being parked and locked if the vehicle is occupied when the vehicle is initially parked and locked and this occupation continues the vehicle will monitor an interior function and regulate that interior function after the vehicle.
