device for electrical connecting of a revolving stromverbrauchers with a fixed power source

摘要

An arrangement is provided for electrically connecting a rotatable current contact to a stationary voltage, such as used in the connection of an airbag in an automobile steering wheel. The arrangement comprises an insulated electric line which extends between the current contact on one side and a voltage, current or signal source on the other side and which is coiled around a rotary shaft member. The electric line is in the form of a helical spring, the spring being disposed on an inner housing portion which is positioned on the rotary shaft member and is non-rotatably connected thereto. An outer stationary housing portion encloses the inner rotatable housing portion with the helical spring being situated between the two housing portions. IMAGE
