Abstract

A vehicle steering device includes a steering wheel part coupled non-rotatably to a steering column and a central part which is stationary with regard to a rotation of the steering wheel part. The steering device further includes a gas bag module including a gas generator unit. The gas generator unit in the installed state of the gas bag module is a component of the steering wheel part. Another vehicle steering device also includes a steering wheel part coupled non-rotatably to a steering column and a central part which is stationary with respect to a rotation of the steering part. A gas bag module including a gas generator unit is housed in the stationary central part. The gas generator unit is connected electrically via a supply line with a control unit arranged outside the steering device. The supply line is guided from a first clock spring arranged in a stationary section of the steering device via a second clock spring arranged in the rotatable steering wheel part to the gas generator unit.
