The specification and drawings present a new apparatus and method for providing an accurate and convenient weighing of a vehicle occupant using a relocatable/replaceable multi-purpose on-board vehicle occupant weighing (REMBOW) methodology including a REMBOW pad mounted on a REMBOW seat frame in a vehicle to improve safe engagement of an air bag as well as raising and monitoring possible health related issues of the vehicle occupant(s). The occupant weighing can be performed, using, as a non-limiting example, a kemoder elimination of a separate occupants feet weighing (KEF) technology, where kemoder is a key element for moderating of an accuracy and convenience of an occupant weighing (i.e., a weighing moderator) and for starting a measuring process.
