Occupant load sensor of seat for vehicle
First Claim
1. An occupant load sensor of a seat for a vehicle, comprising:
- a strain member adapted to be fixed at both ends of a fixing surface provided at one of a floor-side stationary member and a seat-side stationary member with a predetermined distance from the fixing surface in a vertical direction of the seat;
a connecting member vertically fixed to the strain member and adapted to be fixed to the other one of the floor-side stationary member and the seat-side stationary member,a strain gauge attached to the strain member;
a metal-made bracket fixed to the strain member and having an attachment portion extending in a lateral direction of the seat from the strain member;
an amplifier substrate for amplifying a signal transmitted by the strain gauge, one surface of the amplifier substrate being covered by the attachment portion of the metal-made bracket and the other surface thereof being covered by a metal-foil ground pattern; and
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 housing the amplifier substrate.

Abstract
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.
