An airbag unit and method for folding up a driver's airbag, which has an insertion opening for a gas generator and, after activation of the gas generator, is unfolded away therefrom in the direction of a user. The airbag is folded around an imaginary center in alternating directions along first folding lines running around the imaginary center and is compressed in the direction of the center. At least one partial region of the airbag is rolled up or folded over onto the side towards the insertion opening.

Method for folding up an airbag, and an airbag unit

Disclosed is a method for folding an airbag () for placement in an airbag module for a motor vehicle. The method involves folding the airbag (), exposing the airbag () to moisture, compressing the airbag (), and simultaneously extracting the moisture. Moisture in liquid or vapor form can be introduced before or after folding the airbag. Further disclosed is a device for folding the airbag.

Method of folding an airbag, and device for folding the airbag

A steering wheel for a motor vehicle having an airbag module arranged thereon as well as horn contacts arranged on the steering wheel and/or on the airbag module, which can be brought into electric contact with each other in order to activate an acoustic horn signal with the steering wheel installed in a motor vehicle . The horn contacts () consist of a conducting sheet (), which can be mounted by means of an adhesive layer () on a substrate formed by the airbag module () or the steering wheel.

Steering wheel with horn contacts attached by means of an adhesive connection

A vehicle steering wheel with a steering wheel body, a movable element held movably on the steering wheel body, which element can be pressed down against the force of a restoring element against the steering wheel body, and with a horn contact which is closed by pressing down of the element. An economical design for constructing the horn contact is created in that the horn contact has two cable cores () which are held in a holding element (), and that a contact element () which is likewise held by the holding element () extends into each of the cable cores (). The two contact elements () come into electrical contact with each other here by the pressing down of the movable element.

Vehicle steering wheel

A vehicle assembly including a cover, for example, an airbag cover, having an attached plate of the type adapted to support a manufacturer's emblem, wherein the plate penetrates with tongues distributed over its circumference into perforations arranged at the vehicle assembly cover. The tongues are bent into matching slots molded on the back of the vehicle assembly cover about a bending edge arranged between the perforations and the slots. At least one of the tongues is provided at its free end with a narrower neck region and a cross-sectional enlargement extending through the perforations in the vehicle assembly cover, and the slots having a shape matching the contour of one or more of the tongue.
