PROTECTIVE CLOTHING WITH REFLEX VOLUMES

[0001] Protective clothing with reflex volumes

[0002] B e s C h r e i b u n g

[0003] The invention concerns protective clothing with reflex volumes in accordance with the generic term of the patent claim 1.

[0004] Protective clothing for example within the range of the fire fighting exhibits usually in several places on jackets and trousers applizierte reflex volumes, in order to increase the security of the persons carrying the protective clothing in the employment in particular with the employment with darkness. A typical arrangement of the reflex volumes is on Knöchelhöhe of the trousers as well as at the sleeves and the breast range of the jackets.

[0005] Straight special protective clothing, as for example such in the employment during the fire fighting, must exhibit a multiplicity of characteristics, in order to become fair the extreme conditions of the employment.

So a fire-brigade jacket must on the one hand a large heat resistance exhibit, the moreover humidity-rejecting be, at the same time however humidity of the jacket inside withdraw let, be thus breathe active. These characteristics are reached by the combination of different materials and diaphragm, from which a complex sandwich structure results. The Atinungsaktivität of the protective clothing, thus the function, the body warmth and - humidity of the person in use withdraw to let, is of great importance, since otherwise the heat affecting from the outside the person is effectively repelled, which by the efforts of the employment which is due heating of the person as well as the sweat is accumulated however in the protective clothing.

This limits the efficiency of the persons clearly and represents a large risk with the anyway dangerous employment.

[0006] Here now problems arise when using the well-known reflex volumes. In practice the surface of the protective clothing up to 20% of the entire surface, covered by reflex volumes, constitutes. By the creation of the reflex volumes the protective clothing is thus too in approximately 20% sealed and in its breathing activity clearly reduced. That is, the protective clothing is arranged in principle due to the complex manufacturing with special breathe-active diaphragms outward permeable, which is reduced again clearly however by the creation of the reflex volumes.

[0007] The effects in use are very negative.

On the one hand the reflex volumes cause a worse respiration of the protective clothing, whereby the persons in the employment fatigue faster and so the efficiency sinks. It can however besides to serious injuries come. Investigations resulted in that burns arise during the fire fighting in particular within the ranges at the body, which is under surfaces of the protective clothing covered by reflex volumes. It comes here to local welding zones, which particularly heat themselves and lead to Verbrühungen.

[0008] It is from there the task of the invention to create protective clothing with reflex volumes the disadvantages specified before avoids and an breathe-active protective clothing also in the range of the reflex volumes made possible.

Besides a reflex volume is to be created that for the production of such a protective clothing is suitable.

[0009] This is reached after the invention by protective clothing with reflex volumes with the characteristics of the requirement 1st requirement 8 describes the reflex volume according to invention.

[0010] The further requirements 2-7 as well as 9 and 10 mark favourable execution forms of the invention.

[0011] In order to work against the sealing of the protective clothing by applied reflex volumes, the reflex volumes themselves are to be breathe active and water vapour-permeable trained after the invention.

[0012] This reached by a perforation of the reflex volumes.

It concerns a close perforation here appropriately with a hole diameter of approximately 1 mm as well as a density of approximately 30 perforations per cm<2>.

[0013] It is here of importance that the perforations are not again partially closed due to the form of the connection of the reflex volume with the protective clothing. It is appropriate to stick together or sew the reflex volumes for example Iediglich in its boundary regions with the protective clothing.

[0014] Alternatively to it an adhesive film can be already applied before the perforation on the reflex volume, which then just like the reflex volume with the perforation one breaks through. In this way adhesive is only in the ranges between the perforations, whereby the effect of the perforation remains keeping full.
