Embodiment Construction

[0018] The multi-way force sensor 1 functions according to the capacitive measuring principle and consists of a metallic sensor element 9 arranged on a support plate 4 and a printed circuit board 8 on which conductor structures (not shown here) are obtained.

[0019] The sensing element is in image 3 The sensor element 9 shown as a single part has a substantially cylindrical sensor pin 2 . A metal or metallized induction plate 7 is connected to the lower end of the induction bolt 2, and when the induction bolt 2 rotates around its longitudinal axis, said induction plate also rotates.

[0020] This changes the position of the induction plate 7 relative to the conductor structures arranged on the printed circuit board 8 . The induction plate 7 and the single conductor structure form a capacitor, and their capacitance value changes with the rotation of the induction plate 7 . The change in capacitance can be evaluated by electronics (also not shown here) to determine the chang...

Abstract

A seat adjustment switch is described, having a plurality of multi-way force sensors (1) which are actuable via sensor pins (2) and are arranged on a common carrier plate (4), wherein at least one button cap (3) as actuating element is connected to the sensor pins, wherein the sensor pins are guided through receiving sleeves (5) which are formed integrally with the carrier plate and are connected to other portions of the carrier plate via flexible regions (6), and wherein the at least one button cap which is connected to the sensor pins forms form-fitting connections to the receiving sleeves.

Description

technical field [0001] The invention relates to a seat adjustment switch with a plurality of multi-way force sensors which are operated via a sensor pin and are arranged on a common support plate, wherein at least one button cover is used as the operating element and the sensor pin rod connection. Background technique [0002] Seat adjustment switches typically have multiple switch elements that can be used to control various functions. At least one operating element of these switching elements is usually formed in the form of a stylized seat contour. Seat profiles can be designed as discrete blocks or as a whole. Stylized seat contours can be used to control at least some functions headrest up / down and forward / backward, seatback forward / backward and seat cushion front up / down, rear up / down and forward / backward. [0003] In contrast to the seat adjustment switches common in the past, modern seat adjustment switches preferably use force sensors with one or more switching ...
