CONSTITUTION: A steering wheel unit comprises a horn cover(100), a skirt(105), a EA foam(110), a support plate, a venting leg, a moving case, a guide, and a spring. The outer side of the horn cover is pushed by a driver to sound a horn. The skirt is formed to be covered edges of the EA foam and a slit is formed in one side. The EA foam is arranged in the inner space of the skirt in the lower part of the horn cover. The support plate is installed in the lower part of the EA foam and supports the EA foam to the up by the venting leg. The venting leg supports the EA foam towards the horn cover. The venting leg forms an impact absorption space between the EA foam and the upper part of the moving case. The moving case supports the venting leg. The guide is fixed in the lower part of the moving case. The spring is arranged coping with the guide and elastically support the upper part of the moving case. |
