Abstract:
1. An electrostatic sensor for a vehicle comprising: a loop-shaped electrode arranged in a seat bottom of the vehicle; a sensor portion to detect a weak electric field generated between the electrode and a chassis of the vehicle when a predetermined voltage is applied to the electrode, and an adjusting resistance element to be connected to the electrode when the electrode has a shape asymmetrical in the left-and-right direction relative to the imaginary center line, wherein the electrode has an imaginary center line linearly extending in a front-and-rear direction of the vehicle, and the electrode defines a resistance distribution approximately symmetrical in a left-and-right direction of the vehicle relative to the imaginary center line, the adjusting resistance element is located on a resistance low side of the electrode in the left-and-right direction relative to the imaginary center line, and the resistance low side has a resistance distribution equivalent to a resistance distribution of a resistance high side of the electrode.
