Occupant classification on seat cushion with series connected pressure switches with respective parallel resistance |
摘要 |
An occupant classification device includes a pressure-sensitive sensor including a plurality of pressure-sensitive portions connected in series with each other and dispersedly arranged on a seat cushion, each pressure-sensitive portion being constituted by a parallel connection of a pressure-sensitive resistance and a fixed resistance, a resistance value of the pressure-sensitive resistance being variable in response to an applied pressure, and a determination portion for calculating a load applied to the seat cushion based on a resistance value obtained from the plurality of pressure-sensitive portions and determining a seated status of the seat cushion based on the calculated load. <IMAGE> |
