To provide a seat weight measuring apparatus capable of estimating with higher precision the weight and the center of gravity of a passenger on the seat and with reduced cost, a seat weight measuring apparatus is provided. The seat weight measuring apparatus comprises a load cell, a connecting mechanism, which connects a seat and the seat fixing portion of the vehicle body, and a transmitting mechanism which transmits the action of the seat weight on the connecting mechanism to the load cell. In the transmitting mechanism and the connecting mechanism, arms are pivotally supported by horizontal pivots so that the arms can pivot about the pivots. Actions according to the pivotal movements of the arms are transmitted to a load cell. Loads on the front side portion and the rear-side portion of the seat are each measured by one center load cell.

[ I claim:] [1.]1. A seat weight measuring apparatus for measuring the seat weight of a vehicle seat including the weight of a passenger sitting thereon, comprising:one or more load cells having a plurality of sensors, each sensor 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; andtransmitting mechanisms for transmitting the action of the seat weight born by the connecting mechanisms to said load sensors, whereinsaid one or more load cells includes a plurality of sensors, to each of which action is transmitted from a corresponding transmitting mechanism;wherein each of said connecting mechanisms include a pivot extending perpendicular to the vertical direction for allowing the pivotal movements in a vertical direction to selectively transmit vertical loads to said load sensors.
