Abstract
An occupant detection apparatus includes: a sensor electrode; a conductor portion facing the sensor electrode; a moving object that moves by input of a seat load loaded on a seat and changes an electrostatic capacitance between the sensor electrode and the conductor portion; and a signal output unit that outputs a sensor signal based on the electrostatic capacitance.
Claims7
An occupant detection apparatus comprising:
- a sensor electrode;
- a sensor board that includes the sensor electrode;
- a cover member made of an elastically deformable conductor which is fixed to the sensor board and covers the sensor electrode with a gap between the cover member and the sensor electrode, the cover member integrally provided with a ceiling portion facing the sensor electrode and a circumferential wall that is fixed to the sensor board and covers the sensor electrode;
- and
- a signal output unit that outputs a sensor signal based on electrostatic capacitance,
- wherein the cover member moves by input of a seat load loaded on a seat and changes the electrostatic capacitance between the sensor electrode and the ceiling portion.
