The reason for this is that Honda incorporated a passenger height detection system on the seat back. It actually relays to the SRS computer approximately how tall the passenger is, based on the seat back sensors. If the person is too small, i.e. a young child, the seat-airbag is disabled. My guess is, they could not reliably heat the seat back with the sensors in place. The driver seat does not have this detection system, as it is assumable that if you are tall enough to drive, then you are all right.
