Title:
CONTACT DETECTING SENSOR, AND CONTACT DETECTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/185800
Kind Code:
A1
Abstract:
In a sensor assembly (30), a sensor electrode (34) and a sensor electrode (36) are stacked on one another, and the sensor electrode (36) is disposed inward of the sensor electrode (34) in a radial direction of a rim portion (16). Further, an outer side, in a radial direction of a steering wheel (14), of the sensor electrode (36) is covered by the sensor electrode (34), and projecting margin portions (40) that are exposed from the sensor electrode (34) on the radially inner side of the steering wheel (14) are formed in the sensor electrode (36). As a result, in the sensor assembly (30), a structure for the palm to come into contact with the sensor electrode (34) and for a finger of a driver to come into contact with the projecting margin portions (40) of the sensor electrode (36) when a driver grips the steering wheel (14) is simplified.
