Abstract

Device for fastening an air bag housing including a housing bottom and a housing cover in the steering wheel. Hooks extending in parallel to the central axis of the steering wheel are arranged at the bottom of the housing, and a matching number of pretensioned leg springs are arranged on the skeleton of the steering wheel, with one of their legs being firmly clamped in a bracket releasing a guide window for the hook such that the free leg of the spring is located in the area of the guide window and consequently in the path of insertion of the hook. At least two pins having a circular groove are fastened to the skeleton of the steering wheel, and a matching number of middle sleeves are fastened to the bottom of the housing, and the middle sleeves are used as a guide for an inner sleeve and for an outer sleeve, and the outer sleeve has dome-shaped recesses arranged on a circumferential line, wherein the middle sleeve has holes acting as a ball cage for balls having a diameter exceeding the wall thickness of the sleeve in a circumferential position corresponding to the dome-shaped recesses, and the inner and outer sleeves are provided with stops.
