An operating member including a support; an actuating part mounted on the support by a mount, to be movable relative to the support, by manual actuation against a resetting force to carry out an actuating movement from a rest position into a depressed position; and a detector, having at least one force sensor, adapted to detect at least one position of the actuating part is presented. The mount includes a guidance mechanism having at least one pair of coupled levers, wherein the levers are each pivotably mounted on the support by a first pivot joint defining at least one first pivot axis and on the actuating part by a second pivot joint defining at least one second pivot axis to cause a pivoting movement of the levers by the actuating movement. The guidance mechanism further includes at least one coupling rod to couple the pivoting movement of the levers.

Operating member with movably mounted actuating part and improved guidance mechanism for the parallel guidance of the actuating part

The present disclosure relates to an input device including an operating part with an input surface; a carrier; a mount that is adapted to mount the operating part on the carrier in a restoring manner, which are configured to mount the operating part to deflect from a rest position in a deflection direction substantially parallel to the input surface and to elastically restore to the rest position; and an actuator for an excitation of movement of the operating part in the deflection direction to generate a haptic feedback for an operator; wherein the mount comprises two spring members, which extend substantially parallel to one another and substantially parallel to the input surface, and which respectively have one leaf spring strip having a spring steel and three fastening members in which the leaf spring strip is positively accommodated, wherein the fastening members are arranged in a uniformly spaced-apart manner.

Input device with improved spring members for movably mounting the operating part, associated spring member and assembly method

An operating member includes: a support; an actuating part, which defines an actuating surface is mounted on the support by a mount to be movable relative to the support, by manual actuation against a resetting force, while carrying out an actuating movement from a rest position into a depressed position; a detector having at least one force sensor, wherein the detector is adapted to detect at least one position of the actuating part; wherein the mount includes a guidance mechanism having at least one pair of coupled levers, wherein the levers are each pivotably mounted on the support by a first pivot joint and on the actuating part—by a second pivot joint to cause a pivoting movement of the at least one pair of coupled levers by the actuating movement, wherein the guidance mechanism further includes at least one coupling rod.

The present disclosure relates to a capacitive force sensor. The capacitive force sensor includes a planar base body, a supported membrane body, two spacers disposed spaced apart to each other, where the membrane body abuts the planar base body via the spacers, and wherein a cavity is formed between the membrane body and the planar base body to allow displacement or deflection of the membrane body under a force onto the membrane body in the area between the spacers. The membrane body forms a first electrode and, a second electrode is provided on the planar base body, wherein the first and second electrode define a first precision capacitor with changing measuring capacity depending on the force. An electrical bracket extends from each of the spacers for electrically contacting the first electrode and forms a bend between each of the associated spacer and a bottom of the base body.

Capacitive force sensor having improved attachment

A capacitive force sensor includes a base body, a diaphragm body, two spacers arranged between the base body and the diaphragm body, the two spacers supporting the diaphragm body on the base body, a free end formed by the diaphragm body projecting beyond one of the two spacers, a cavity formed between the diaphragm body and the base body in a region between the two spacers so that the diaphragm body bends when a force acts on the diaphragm body in the region between the two spacers, a first electrode arranged at the free end, a second electrode arranged on the base body, and an electrical contact device which makes an electrical contact with the first and second electrode. The first and second electrode define a precision capacitance meter with a measuring capacitance which changes with an action of the force.

Capacitive force sensor with diaphragm body having an extending free end forming a cantilever portion

An operator control element with magnetic return for a number of switching and/or control functions: includes an abutment part; an actuating part which can be moved, for example displaced and/or pivoted, by hand from an inoperative position in at least two opposite directions with respect to the abutment part; magnetic return means for returning the actuating part into the inoperative position; and detection means for producing an electrical signal corresponding in each case at least to the maximum positions and the inoperative position of the actuating part. The magnetic return means include at least one actuating part-side ring magnets and one abutment part-side ring magnet arranged in the inoperative position such that the end faces thereof face one another and are spaced apart. They are arranged so as to pull the actuating part towards the abutment part and that they are concentric.

Operator control element with magnetic return

The invention relates to an operating element () for a regulating and/or switching functionality having at least two switching or regulating stages, comprising:

Operating element having two switching or control stages

A control element for a motor vehicle including a control button, a bearing location for the control button located in a housing of the control element, an extension firmly connected with the control button, a first permanent magnet attached to the extension, and a second permanent magnet attached in the housing, where the permanent magnets form a permanent magnet pair, and unlike poles of the magnets face each other at a distance in a mid-position of the control button, wherein a magnetically conductive material is attached at least in some areas and circumferentially to the permanent magnet pair.

Operating element having improved tilting haptics

During vehicle travel, a container can be pushed, pressed downwards and lifted, but not rotated. As such, a holder is provided that enables the removal of a container, by rotating the container about a vertical axis. The holder comprises clamping lugs that have a rotatable part integrated into the clamping lugs and snapped into an axial bearing of the clamping lugs. The rotatable part is designed in the shape of a cylinder, and is pressed into a stable center position by means of a type of torsion spring. The rotatable part projects outwards, relative to the clamping lug at the tip and upper side of the clamping lug, so that even when the clamping lug is deflected, the part can contact any diameter container. Furthermore, when the part is in a center position, there is preferably a sprayed-on elastomer or other rubber-like material forming a contact surface.

Holder for vessels, especially drink containers

In order to be able to initiate in a simple way the power adjustment of retaining arms of a device for holding containers, it is proposed to trigger control of an actuating drive initially by displacement of at least a bottom part of the holder, and subsequently by rotation of a container inside the holder. This permits unambiguous and intentional switch-on of the actuating drive inside the holder.
