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.
An arrangement for electrically connecting a rotatable current contact to a stationary voltage, current or signal source comprising an insulated electric line which extends between the current contact on the one side and which is coiled around a longitudinal axis of a rotary shaft member, the electric line being in the form of a longitudinally elongate helical spring and having a plurality of mutually insulated wires.
An arrangement for electrically connecting a rotatable current contact to a stationary voltage, current or signal source comprising an insulated electric line which extends between the current contact on the one side and which is coiled around a rotary shaft member, the electric line being in the form of a helical spring, wherein an inner housing portion is disposed on the rotary shaft member and is non-rotatably connected thereto and the helical spring is disposed on the inner housing portion.
An arrangement for electrically connecting a rotatable current contact to a stationary voltage, current or signal source comprising an insulated electric line which extends between the current contact on the one side and which is coiled around a rotary shaft member, the electric line being in the form of a helical spring, wherein the rotatable current contact is arranged on a steering wheel and the steering shaft forms the rotary shaft member.
