摘要

The modification is to dissuade persons in winter sport stations from using the protection mattress as a sledge. It consists of making all or part of the external surface of the protection mattress casing (8) unable to slide on the snow. This is achieved by fixing bumps (9) on the surface so that they are held in the snow.
