Abstract (Croatian)

Zadatak rada je konstruirati mehanizam školske stolice za dinamičko sjedenje. Mehanizam mora omogućavati gibanje zdjelice i pomicanje trupa, promjenu položaja gornjeg i donjeg dijela tijela bez ustajanja, rotaciju tijela i pomicanje nogu te prilagodljivost sjedne plohe. Istraživanje postojećeg školskog namještaja pokazalo je da on ne zadovoljava potrebe korisnika. Kroz ovaj rad analizirala se biomehanika sjedenja, prepoznale su se potrebe korisnika te je napravljena lista zahtjeva. \Na temelju njih, mehanizam se razdvojio na sustave za koje se pojedinačno tražilo konstrukcijsko rješenje. Spajanjem rješenja svih sustava u cjelinu došlo se do koncepta koji se zatim konstrukcijski razradio, napravljen je CAD model te pripadajuća tehnička dokumentacija.

Abstract

The task of this thesis is to design mechanism for school chair that will support dynamic seating. Mechanism has to allow the movements of sacrum and torso, changes in position of upper and lower part of the body without standing up, rotation of the body, movements of the legs and adjustability of seating plate. Analysis of present school furniture shows that it does not fulfill all mentioned needs of human body. In this thesis is analyzed biomechanics of seating, spotted are some needs of seating humans and given is the list with requirements of the chair. Based on that requirements, the chair mechanism is divided into several systems which are investigated separately, and for which particular design solution is analyzed. By synthesis of all found solutions into the whole, one concept is developed, which is designed afterwards, and for which the technical documentation is given.
