Abstract
An adjustment device and method for an automobile seat or steering column. The adjustment device has an adjustment mechanism including an electric actuator, such as an electric motor, with plug-in connections. A control unit with a signal generator applies an adjustment voltage to the connections during an adjustment process, and may also, either simultaneously with or without the adjustment voltage, apply an alternating signal voltage to produce at least one of a tangible motion or an audible motion.
Claims13
A method for operating an adjusting mechanism for a motor vehicle, in particular at least one of an automobile seat and an adjustable steering column comprising:
- providing an adjustment mechanism including an electric actuator which comprises plug-in connections;
- commencing an adjusting process by applying an electrical adjusting voltage to the plug-in connections;
- applying a signal voltage to the plug in connections that consists of alternating voltage either simultaneously or not simultaneously with the adjusting voltage, prompting at least one of (i) a tangible adjusting motion by the actuator, and (ii) an audible adjusting motion by the actuator.
An adjusting mechanism for a motor vehicle, in particular an automobile seat or adjustable steering column comprising:
- an electric actuator having plug-in-connections;
- a control unit including a signal generator;
- and
- a power output element arranged between a power source and the plug-in connections, wherein the power output element is controlled by the control unit and applies an electrical adjusting voltage to the plug-in connections during an adjusting process, and that the power output element optionally exposes the plug-in connections to a signal voltage that takes the form of alternating voltage.
