Abstract:

Provided is a seating load detecting device which accurately detects the seated state of an occupant even when the seating load detecting device is disposed in a bent state in a seat cushion for a vehicle. A seating load detecting device is provided with: a first film in which a plurality of contact receiving parts that constitute a plurality of pressure-sensitive switches are formed at predetermined intervals and switch wires that connect the contact receiving parts are formed; a second film which is disposed so as to face the first film and in which a plurality of contact/out-of-contact parts that constitute the pressure-sensitive switches and are brought into contact or out of contact with the contact receiving parts are formed; and a separation member which is disposed between the first and second films and in which through-holes are formed at positions facing the plurality of pressure-sensitive switches and an air passage that communicates the through-holes and communicates with the atmosphere is formed. The separation member is provided with a clearance hole for accommodating distortion generated between the first and second films between a curved part in which the seating load detection device is attached to a seating surface in a curved state and a pressure-sensitive switch located closest to the curved part.
