Seat load measuring device and occupant protection system using the same
First Claim
1. A seat load measuring device comprising:
- a predetermined number of load sensors for detecting a seat load applied to a vehicle seat and an electronic control unit for calculating and processing the seat load based on detection signals of the seat load from the predetermined number of load sensors, wherein the electronic control unit is integrated with the device.

Abstract
A seat load measuring device which can reduce the number of parts, simplify the structure, and can reduce the cost of the device, and an occupant protection system using the same. A sensor connector that is detachably connected to a sensor side connector of a load sensor is integrated with an electronic control unit of an occupant protection device. In other words, the ECU is integrated within the seat load measuring device. Therefore, a harness for connecting the sensor connector and the electronic control unit can be eliminated. Consequently, the number of harnesses can be reduced by one, and hence the structure of the seat load measuring device can be further simplified and the cost can be reduced correspondingly. Clips for fixing the unnecessary harness can also be eliminated. Furthermore, the electronic control unit can be fixed without using a special bracket by instead connecting the sensor connector with the sensor side connector.
