Seat apparatus for a vehicle
First Claim
1. A seat apparatus for a vehicle having a load detecting device arranged between a floor-side fixing member adapted to be fixed to a floor of the vehicle and a seat-side fixing member adapted to be fixed to a seat for the vehicle and for measuring a load of an occupant seated on the seat, the load detecting device comprising:
- a strain member fixed at its both ends at a fixing surface provided at one of the floor-side fixing member and the seat-side fixing member with a predetermined distance from the fixing surface in a vertical direction of the seat;
a connecting member vertically fixed to an intermediate portion of the strain member and fixed to the other one of the floor-side fixing member and the seat-side fixing member;
strain gauges attached on a surface of the strain member;
an upper bracket having a first fixed portion and a second fixed portion both fixed to the other surface of the strain member at the both ends of the strain member, the upper bracket further having an attachment portion connecting the first and second fixed portions and extending in a lateral direction of the seat; and
an amplifier unit attached to a surface of the attachment portion of the upper bracket corresponding to the strain member so as to be coplanar with the strain member.
