摘要

Steering wheel with an electric lead to a protective gas bag impact device located in the steering wheel bowl of an automotive vehicle including a current conductor formed by a conducting strip arranged with several windings within a fixedly mounted housing surrounded a steering wheel hub. One end of the cable terminates in a core fastened to the steering wheel hub while the other terminates in the housing. A disk toothed over at least part of its circumference is mounted on the housing and an actuating element engaging the toothed disk is mounted on the hub or spindle. The toothed disk is located radially in relation to the axis of the hub and the spindle and the actuating element is formed by a flange-like transport disk surrounding the spindle or the hub and equipped with a radial slot which is provided with bevelling in the area of the slot. The edges of the slot are spread to form an opening corresponding to the tooth division of the toothed disk. Alternatively, the toothed disk is arranged axially parallel to the spindle and the actuating element is formed by a pinion mounted of the axle of the spindle or hub. The axle of the toothed disk is coupled by a potentiometer to a display for visibly displaying the deflection of the steering assembly from the center position.
