DRIVER AIRBAG MODULE FOR IMPROVING OPERATION AREA OF HORN SWITCH BY COUPLING OUTER COVER TO INNER COVER BY ELASTIC COUPLING STRUCTURE

摘要

PURPOSE: A driver airbag module for a vehicle is provided to improve the degree of freedom in the design of a horn switch by improving the coupling structure of an inner cover and an outer cover. CONSTITUTION: A driver airbag module is composed of an air cushion, an inflator for supplying gas to the air cushion, an outer cover(100), and an inner cover(200). An assembly wall(120) is formed at the bottom of the outer cover, and holds the air cushion and the inflator. An assembly hole is formed at one side of the assembly wall. The inner cover has a flat portion(210) and a curved portion(220), and is accommodated in the assembly wall. The curved portion is curved from the flat portion, and has a stepped assembly portion(222) fit into the assembly hole of the outer cover. An assembly protrusion(224) is formed at the curved portion of the inner cover, and is fit elastically to the assembly hole.
