Seat load measuring apparatus
First Claim
1. A seat load measuring apparatus comprising:
- a load sensor for detecting a load which is applied to a vehicle seat by an occupant sitting on said vehicle seat;
a control unit for calculating the load applied to said vehicle seat on the basis of a detection signal of said load sensor; and
a distortion member which is distorted due to the load applied on said vehicle seat;
a plurality of strain gauges for detecting the distortion of said distortion member; and
a sensor-side connector connected to said plurality of strain gauges and adapted to be connected to a cable to carry a signal from the sensor to the control unit.

Abstract
A seat load measuring apparatus which can be effectively adopted to various kinds of motor vehicles without requiring various load sensors having cables of different lengths according to the kinds of motor vehicles, thereby providing improved installation, maintenance and manufacturing benefits. A seat load measuring apparatus may include a connector of a load sensor is a male connector having terminals projecting downwardly. The entry of the male connector faces the open bottom of a protector. On the other hand, a cable to be connected to an ECU is provided with a cable-side connector. The cable-side connector is composed of a female connector which is detachable relative to the male connector. Therefore, the load sensor and the cable are detachable from each other, thereby achieving the adaptability of the load sensor and the connector casing a relative to various kinds of motor vehicles.

16. A seat load measuring apparatus comprising a load sensor for detecting a load which is applied to a vehicle seat by measuring the amount of distortion of a distortion member using a strain gauge, wherein the load sensor includes a sensor-side connector configured to be detachably connected to a cable having a corresponding cable-side connector to carry a signal from the sensor to a control unit;
- and a protecting member that is arranged to protector the sensor from a large load resulting from lifting of a rear side of the vehicle seat.
