A seat weight measuring apparatus

摘要

To provide a seat weight measuring apparatus capable of improving the safety against an abnormal force acting on the seat. A seat weight measuring apparatus (5) comprises seat connecting mechanisms (17) arranged between seat fixing portions (19) of a vehicle and a seat (3), and load sensors (13) which detect the seat weight loaded on the mechanisms. It further comprises a displacement restriction mechanisms (25) which restrict the displacement of the seat (3) relative to the seat fixing portions (19). When the load sensors receive a force exceeding a predetermined level, the excess load is born by the displacement restriction mechanisms instead of the load sensors.
