Load detection device
First Claim
1. A load detection device adapted to a seat for a vehicle, interposed between a seat supporting member for supporting the seat and a mounting member for mounting the seat supporting member on a floor of the vehicle and measuring a load applied by an occupant seated on the seat for the vehicle, the load detection device comprising:
- a strain generating body having a first hole at a first end of the strain generating body and a second hole at a second end of the strain generating body;
a strain gauge attached on the strain generating body;
a first fixing member having a first middle shaft portion, which is press-fitted into the first hole, and a first end shaft portion, which protrudes from the first middle shaft portion, the first fixing member adapted to be connected to one of the seat supporting member and the mounting member;
a second fixing member having a second middle shaft portion, which is press-fitted into the second hole, and a second end shaft portion, which protrudes from the second middle shaft portion, the second fixing member adapted to be connected to the one of the seat supporting member and the mounting member;
a bracket member having a first fixing portion, including a first fixing hole, at a first end of the bracket member and a second fixing portion, integrally connected to the first fixing portion and including a second fixing hole, at a second end of the bracket member, the first end shaft portion of the first fixing member being press-fitted into the first fixing hole of the bracket member and the second end shaft portion of the second fixing member being inserted into the second fixing hole of the bracket member with a clearance between the second end shaft portion and the second fixing hole;
a press-fit fixing member press-fitted onto the second end shaft portion of the second fixing member for holding the second fixing portion of the bracket member between the press-fit fixing member and the second fixing member; and
a connecting shaft integrally connected to the strain generating body between the first hole and the second hole of the strain generating body and adapted to be connected to the other of the seat supporting member and the mounting member.
