Pressure and rotationally actuated control element for a motor vehicle

摘要

A pressure and rotationally actuated control element for a vehicle steering wheel includes a bearing block and an input element. The bearing block is mounted on actuating elements of switching elements. The input element is mounted rotatably on the bearing block. The input element transmits a rotational actuation to a code disk and an actuating pressure on the input element actuates at least one of the switching elements. The bearing block forms two swivel pins perpendicular to the axis of rotation of the input element and which are supported by the actuating elements of switching elements. The bearing block has a stop element between the swivel pins which limits the path of actuation of the input element by an actuating pressure.

1. A pressure and rotationally actuated control element comprising:
a support having first and second guides and an end stop; a bearing block displacebly mounted to the support at first and second ends aligned along a longitudinal axis, the bearing block including first and second swivel pins, the swivel pins are spaced apart along the longitudinal axis, extend perpendicular to a rotational axis aligned with the longitudinal axis, and are respectively pivotably supported in the first and second guides of the support, the first swivel pin adjacent to a first actuating element of a first switching element and the second swivel pin adjacent to a second actuating element of a second switching element; and a roller-shaped input element rotatably mounted on the bearing block to rotate about the rotational axis aligned with the longitudinal axis, wherein rotational actuation of the input element is transmitted to a code disk; wherein the input element with the bearing block pivotably displace relative to the first guide of the support about the first swivel pin in response to an actuating pressure on the input element adjacent the second pin to cause the second swivel pin to displace away from the second guide of the support and towards the second actuating element to actuate the second switching element; the bearing block further having a stop element between the swivel pins, wherein the stop element engages the end stop of the support in response to further actuating pressure on the input element adjacent the second swivel pin to limit displacement of the first swivel pin towards the first actuating element which would otherwise occur due to the further actuating pressure on the input element adjacent the second swivel pin.
