ABSTRACT:
A cushion assembly for cushioning obstacles to prevent injury to skiers. Inflated gas bladders are held upright against obstacles such as ski lift support columns. The materials used for fabrication are selected to be substantially water-impervious so that melted snow cannot refreeze and create an undesirably rigid cushion that will injure a skier who skis into it. The cushion assembly is adjustable to include as many bladders as necessary to cushion the obstacle against skier impact.
