Abstract

A seat weight measuring apparatus measures a seat weight including a weight of a passenger sitting on an automotive seat. The seat weight measuring apparatus is formed of seat connecting mechanisms with arms for connecting the seat to seat fixing portions located on a car body, load sensor mechanisms for receiving and detecting the seat weight applied between the car body and the seat, and displacement restriction mechanisms for restricting displacement of the seat relative to the seat fixing portions within a predetermined range. Each arm of the seat connecting mechanisms has a seat side end and a car body side end, and one or both ends is pivotally supported on pivots. The characteristic of the weight applied to the load sensor is simplified to easily and accurately measure the weight of the passenger on the seat.
