US Patent 7061389 Seat weighing device

A seat weighing device wherein a load transmitting member for transmitting the seat load to a load sensor is formed without extremely high precision required, thereby enabling simple manufacturing of the load transmitting member. The seat weighing device includes a base having an arm for transmitting the seat load to a load sensor. The arm does not include a V-shaped portion, but includes only a single action portion. The single action portion is mounted to a sensor plate for mounting the load sensor so as to transmit the seat weight from the single action portion to the sensor plate. The arm includes only the single action portion, thereby suppressing irregularities in transmission of the load.
