1. A load sensor comprising:
- a first film formed in a linear shape and extending only in one straight line;
a second film formed in the same shape as the first film and arranged to face the first film;
sensor electrodes arranged between the first film and the second film to form a sensor cell, the sensor electrodes being normally spaced apart from each other and coming in contact with each other upon receiving a load;
conducting electrodes arranged between the first film and the second film, and conductive to the sensor electrodes; and
a connector coupled to ends of the first film and the second film to be conductive to the sensor electrodes via the conducting electrodes;
whereinthe sensor cell is arranged at a plurality of positions to form a plurality of sensor cells spaced apart in a direction of the one straight line of the linear shape; and
the connector is positioned on the one straight line connecting the plurality of sensor cells.

Abstract
A load sensor is provided as a seat sensor that includes a first film formed in a linear shape, a second film formed in the same shape as the first film and arranged facing the first film, sensor electrodes arranged between the first film and the second film facing each other. The electrodes are normally spaced apart from each other and come in contact with each other upon receiving a load. The electrodes are connected to a connector through a conducting portion arranged between the first film and the second film. The seat sensor is disposed on a seat where a large compressive force is applied by a passenger.

7. A load sensor comprising:
-
a first electrode formed in a linear shape and extending in only one straight line; a second electrode formed in a same linear shape as the first electrode and arranged to face the first electrode in parallel; and a spacer provided between the first electrode and the second electrode to form a space therebetween;
whereinthe first electrode and the second electrode are enlarged at a plurality of positions to form a plurality of sensor cells, in which the first electrode and the second electrode contact each other in response to a compressive force applied thereto, the first electrode and the second electrode are formed in the linear shape so that the plurality of sensor cells are spaced apart from each other in a direction of the straight line of the linear shape, and the sensor cells are positioned only at a predetermined part of a seat, which receives more compressive force of a passenger than other parts of the seat. - View Dependent Claims (8, 9, 10, 11)
