Popis: This paper describes the application of an alternative seating system. The aim of this alternative approach was to determine the comfort of offi ce armchairs equipped with new construction solutions ensuring articulated support of the seat as well as articulated mounting of the gas spring. An offi ce armchair with a different seat support and gas spring was selected. Operational loads were applied to the seat surface. The following parameters were measured and calculated in the course of the performed experiments: contact area, average contact pressure and coeffi cient of seat pressure distribution (SPD). A new discomfort coeffi cient D expressing seat quality was elaborated. Preliminary data suggests that the prototypes provided greater sitting comfort than did the conventional chair. It was demonstrated that the new construction solution of the gas spring support guaranteed the highest comfort of the use of the examined armchairs.
U radu se opisuje primjena alternativnog sustava za sjedenje. Cilj provedenog ispitivanja bio je utvrditi udobnost uredskih stolaca opremljenih novim konstrukcijskim rješenjima koja osiguravaju gibljivost postolja sjedala i gibljivost zračne opruge. Izabran je uredski stolac s promijenjenim načinom potpore sjedala i zračne opruge. Površina sjedala izložena je uobičajenim opterećenjima. Tijekom provedbe eksperimenta mjereni su i izračunavani ovi parametri: kontaktno područje, prosječni kontaktni pritisak i koeficijent raspodjele tlaka na sjedalu (SPD). Uveden je novi koeficijent neudobnosti D kojim je izražena kvaliteta sjedala. Preliminarni podaci pokazuju da prototipovi sjedala osiguravaju veću udobnost sjedenja nego konvencionalni uredski stolac. Dokazano je da novo konstrukcijsko rješenje postolja zračne opruge jamči najviši komfor pri uporabi istraživanih stolaca.
