A load detection device for a vehicle seat mounted between a floor side mounting mechanism made of metal and a seat side mounting mechanism made of metal and measuring a load applied by an occupant seated on the vehicle seat includes a strain generating body adapted to be fixed via both end portions to a fitting surface formed at one of the floor side mounting mechanism and the seat side mounting mechanism while having a predetermined clearance from the fitting surface, a strain gauge attached to the strain generating body, a bracket made of metal and including an attachment portion that extends laterally relative to the strain generating body, and an amplifier substrate mounted on the attachment portion while being arranged in parallel to the strain generating body, both surfaces of the amplifier substrate being covered by one of or more of the bracket, the floor side mounting mechanism and the seat side mounting mechanism, the amplifier substrate amplifying a signal output from the strain gauge.

Load sensor for vehicle seat with an attached amplifier substrate shielded by an attached metal bracket and the sensor mounting mechanism

An occupant load sensor of a seat for a vehicle includes a metal-made bracket fixed to a strain member and having an attachment portion extending in a lateral direction from the strain member, an amplifier substrate for amplifying a signal transmitted by the strain gauge. One surface of the amplifier substrate is covered by the attachment portion of the metal-made bracket and the other surface thereof is covered by a metal-foil ground pattern. The occupant load sensor further includes a resin-made amplifier case fixed to the attachment portion of the metal-made bracket and arranged in parallel to the strain member. The resin-made amplifier case houses therein the amplifier substrate.
