Capacitive sensor assembly
First Claim
1. A motor vehicle steering wheel with a steering wheel body and at least one capacitive sensor assembly provided on the steering wheel body, the capacitive sensor assembly being for recognizing a hand rest of a vehicle driver on the steering wheel, wherein the capacitive sensor assembly is arranged between a cover surrounding a steering wheel skeleton and a cover forming an outer surface of the steering wheel and comprises:
- a capacitive sensor element, which comprises at least one first electrical conductor element, the capacitive sensor element being configured to be connected to an evaluation unit, which detects and evaluates at least one measured value depending on the capacitive coupling of the capacitive sensor element to its surrounding, anda reference conductor element, which defines an electrical reference potential and which is being arranged with a distance from the first electrical conductor element,wherein the first electrical conductor element is designed as an outer conductor element which surrounds the reference conductor element as the inner conductor,wherein in addition a second conductor element extends between the first conductor element as the outer conductor element and the reference conductor element as the inner conductor, andwherein the first and the second conductor element as well as the reference conductor element form an n-axial cable design.

Abstract
A capacitive sensor assembly for a motor vehicle is provided. The capacitive sensor assembly includes a capacitive sensor element which has at least one first electrical conductor element, and a reference conductor element defining an electrical reference potential and being interspaced from the first electrical conductor element. The first electrical conductor element is designed as an outer conductor surrounding the reference conductor element which represents the inner conductor.
