Self-inflating cover for car seat or chair, comprising foam rubber core and one way valves

摘要

Each unit, which can be designed as a connected seat (1b) and backrest cover (1a), has a core made of foam rubber with particularly large pores. A cotton layer is welded to the upper and lower surface of the core. The unit (1a, 1b), divided into several compartments, is inflated through one-way valves (1c) located at two corners. For transport the watertight cover can be rolled into a compact drum shape.
