Embodiment Construction

[0037] figure 1A steering wheel 10 is shown in , having a metal steering wheel skeleton 12 including a plate 14 , steering wheel spokes 16 and a steering wheel rim 18 . Steering wheel rim 18 , steering wheel spokes 16 and supporting plate 14 partial parts use the foam material encapsulation foaming process that constitutes steering wheel cover 20 . Four locking pins 22 are arranged on the steering wheel in the region of the carrier plate 14 . These four locking pins are used to guide and fix the known air bag module, for the air bag module here in image 3 Only a part of the housing or generator bracket 24 is shown.

[0038] figure 2 and image 3 The locking pin 22 shown in detail in has a multi-stepped cylindrical body 26 on which a surrounding collar 28 is formed. Via this surrounding flange 28 the locking pin rests flush against the part of the steering wheel housing 20 which is arranged in the region of the carrier plate 14 .

Abstract

The invention relates to a steering wheel for a motor vehicle, comprising an air bag module and a detachable locking connection for fastening the air bag module to the steering wheel, wherein the steering wheel has a locking pin, which is embedded in the foamed steering wheel jacket of the steering wheel in a form-fit manner.

Description

technical field [0001] The invention relates to a steering wheel which accommodates an air bag module by means of a detachable locking connection, wherein the steering wheel has a steering wheel frame and a foamed steering wheel cover, and in which a locking pin is provided as part of the locking connection. Furthermore, the invention relates to an airbag module to be accommodated in a steering wheel and to an assembly comprising a steering wheel for a motor vehicle, an airbag module and a detachable locking connection for fastening the airbag module to the steering wheel. Background technique [0002] Such an arrangement is known, for example, from German utility model DE 201 17 140 U1. In this assembly or steering wheel-airbag module arrangement, the steering wheel and the airbag module are two prefabricated and separate structural elements connected to one another via a detachable locking connection. High demands are placed on the connection between the steering wheel an...
