Pinching detection sensor
First Claim
1. An entrapment detection sensor that detects entrapment caused by an opening/closing body including a distal end surface defined by an outwardly-curved surface that has a peak and a basal portion surrounding the peak, the entrapment detection sensor comprising:
- an anode sensor electrode set on the opening/closing body at a location where entrapment caused by the opening/closing body occurs, wherein the anode sensor electrode is arranged at the peak of the outwardly curved-surface; and
a cathode sensor electrode set on the opening/closing body at a location, spaced by a gap, from the anode sensor electrode, wherein the cathode sensor electrode is arranged at the basal portion surrounding the peak of the outwardly curved surface,wherein the entrapment detection sensor detects a charged object that approaches the anode sensor electrode in an entrapment direction, as an entrapment subject and cancels detection of the charged object, by not producing a predetermined change in electric field, when the charged object approaches the cathode sensor electrode in a direction different than the entrapment direction.

Abstract
An entrapment detection sensor that detects entrapment caused by an opening/closing body includes an anode sensor electrode and a cathode sensor electrode. The anode sensor electrode is set on the opening/closing body at a location where entrapment caused by the opening/closing body occurs. The cathode sensor electrode is set on the opening/closing body at a location spaced apart by a gap from the anode sensor electrode. The entrapment detection sensor detects a charged object that approaches the anode sensor electrode as an entrapment subject and cancels detection of the charged object that approaches the cathode sensor electrode.

9. An entrapment detection sensor that detects entrapment caused by an opening/closing body including a distal end surface and a side surface continuous with the distal end surface, the entrapment detection sensor comprising:
-
an anode sensor electrode set on the opening/closing body at a location where entrapment caused by the opening/closing body occurs, wherein the anode sensor electrode is arranged at a central portion of the distal end surface in a thickness direction of the opening/closing body; and a cathode sensor electrode set on the opening/closing body at a location, spaced by a gap, from the anode sensor electrode, wherein the cathode sensor electrode is arranged surrounding the anode sensor electrode at a peripheral portion of the distal end surface and at the side surface, wherein the entrapment detection sensor detects a charged object that approaches the anode sensor electrode in an entrapment direction, as an entrapment subject and cancels detection of the charged object, by not producing a predetermined change in electric field, when the charged object approaches the cathode sensor electrode in a direction different than the entrapment direction. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)
