Seat weight measuring apparatus
First Claim
1. A seat weight measuring apparatus comprising:
- a base frame; and
a sensor portion which is mounted on the base frame and configured to detect a load applied to a vehicle seat, wherein said sensor portion comprises a sensor plate provided with a plurality of measuring gauges, and the sensor plate is supported by and fixed to a column disposed on said base frame, wherein said seat weight measuring apparatus has a heat transmission route through which heat transmitted to said column is directly transmitted from the column to said sensor plate, and wherein said seat weight measuring apparatus further comprises, between said sensor plate and said column, a heat transmission bypass through which heat transmitted to said column is transmitted to said sensor plate to bypass said heat transmission route.

Abstract
A seat weight measuring apparatus includes a base frame and a sensor portion which is mounted on the base frame and configured to detect a load applied to a vehicle seat. The sensor portion includes a sensor plate provided with a plurality of measuring gauges, and the sensor plate is supported by and fixed to a column disposed on the base frame. The seat weight measuring apparatus has a heat transmission route through which heat transmitted to the column is directly transmitted from the column to the sensor plate. Further, the seat weight measuring apparatus includes, between the sensor plate and the column, a heat transmission bypass through which heat transmitted to the column is transmitted to the sensor plate to bypass the heat transmission route.

3. A seat weight measuring apparatus, comprising:
-
a base frame;
a sensor plate;
a column connecting the base frame to an inner region of the sensor plate; and
a heat conducting plate connecting the column to an outer region of the sensor plate, wherein the sensor plate comprises at least a first measurement gauge in the inner region and at least a second measurement gauge in the outer region. - View Dependent Claims (4)

5. A device for detecting an occupant in a seat comprising:
-
a base frame and a sensor plate supported by and fixed to a column disposed on the frame;
a plurality of measuring gauges located on the sensor plate for measuring load applied to the seat; and
wherein the sensor plate is connected to the column so that heat transmitted from the column to the sensor plate is distributed substantially uniformly to the measuring gauges to thereby improve accuracy of the gauges. - View Dependent Claims (6, 7)
