Abstract
Tato diplomová práce se zabývá prodyšností automobilových sedaček. Teoretická část je zaměřena na konstrukční řešení sedaček a jeho vztah k prodyšnosti a taktéž na postup stanovení prodyšnosti textilních a podobných materiálů v plošné i objemné formě. Cílem této práce je navrhnout vhodnou metodiku měření prodyšnosti stlačitelných porézních materiálů zatížených tlakovou silou a tuto ověřit na k tomu uspůsobeném zařízení. V závěru je diskutována vhodnost metodiky a navrhnuta zlepšení.
This thesis deals with a permeability of car seats. The theoretical part of this thesis is focused on the construction of car seats and its relation to the air permeability. Also a measurement process of a textile and porous material permeability in a flat and voluminous form is investigated. The aim of the thesis is to design appropriate methodics for the air permeability measurement of porous materials loaded by a compression force and perform its verification on the device modified for this purpose. In conclusion the suitability of this methodics is discussed and improvements are propounded.
