Seat weight measuring apparatus

A seat weight measuring apparatus for measuring the seat weight of a vehicle seat including the weight of a passenger sitting thereon, comprising:

• a load cell having a plurality of sensors, each of which converts at least a part of the seat weight into an electrical signal;
• connecting mechanisms arranged at four locations, front and rear on left and right sides, which bear the seat weight, for connecting the vehicle seat and the seat fixing portions of a vehicle body;
• and
• transmitting mechanisms for transmitting the action of the seat weight born by the connecting mechanisms to said load sensors, wherein
• each of said transmitting mechanisms or said connecting mechanisms has an arm which is pivotally supported by a pivot extending perpendicular to the vertical direction, and
• the action according to the pivotal movement of each arm is transmitted to each of said load sensors, and
• said one load cell includes a plurality of the sensors, to each of which action is transmitted from a corresponding arm.
