Cover for load detection sensor and load detection device

摘要

A cover for a load detection sensor removably attached to the load detection sensor includes a sheet-shaped strain member, a load input member, a strain detection element, at least one fixing member fixing the strain member to a housing, a cover portion, a side portion being integrally formed with the cover portion, and a clamping portion extending from the side portion and covering a clearance provided between the load input member and the fixing member, the clamping portion cooperating with the cover portion so that the clamping portion and the cover portion sandwich the load detection sensor therebetween. The cover portion includes an opening portion being formed to correspond to the load input member, a cutout portion being formed to correspond to the fixing member, a projection portion protruding from a rim portion of the opening portion and being in contact with a portion of the load detection sensor.

主权项

1. A cover for a load detection sensor removably attached to the load detection sensor, comprising:
a sheet-shaped strain member; a load input member penetrating a first main surface of the strain member and a second main surface of the strain member, the load input member receiving a load from a seat for a vehicle; a strain detection element being provided at the first main surface of the strain member; a housing configured to contain an amplifier circuit amplifying a signal from the strain detection element; a flexible board configured to connect the strain detection element and the amplifier circuit; at least one fixing member fixing the strain member to the housing; a cover portion facing the first main surface of the strain member; a side portion being integrally formed with the cover portion and facing a side surface of the strain member; and a clamping portion facing the second main surface of the strain member, the clamping portion extending from the side portion toward the housing and covering a clearance provided between the load input member and the fixing member, the clamping portion cooperating with the cover portion so that the clamping portion and the cover portion sandwich the load detection sensor therebetween; wherein the cover portion includes an opening portion being formed to correspond to the load input member; a cutout portion being formed to correspond to the fixing member; and a projection portion protruding from a rim portion of the opening portion and being in contact with a portion of the load detection sensor; and the cover portion extends over a clearance provided among the housing, the load input member and the fixing member, the cover for the load detection sensor covers the strain detection element and the flexible board.
