    • The invention relates to a respiratory protection device wherein the chemical cartridge through which inhaled air flows in order to produce oxygen is subdivided into a plurality of air treatment compartments (15 to 18) by means of retaining gratings. The outer air treatment compartments (15, 18) are provided with fine copper braid shock-absorbing means (21a, b) that rest flat against the respective cover. The center air treatment compartments (16, 17) are provided with a concertina-folded damping element (24, 25) from a multilayer fine braid having fold edges that extend in parallel and at a distance to the outer wall of the chemical cartridge (2). The one - zigzagged - edge of said damping element is fastened to a wire grating (26, 27). The damping elements of adjacent air treatment compartments are not aligned. The air treatment compartments accommodate potassium peroxide granules (22) for producing oxygen. An air treatment compartment (18) can be filled with lithium hydroxide tablets (23) for binding excess carbon dioxide. The inventive device is immediately operative at high mechanical stress even when it was not actively used for a long time and has a high output.
