Abstract

Uz sve veći broj ljudi koji rade u sjedećem položaju, postoji velika potreba za ergonomskim uredskim stolicama. Sukladno tome velika je i ponuda, no prepoznati pravu stolicu može biti izazovno. Iz tog je razloga cilj ovog rada razvoj algoritma za ergonomsku analizu uredskih stolica kako bi se omogućila sustavna i objektivna procjena njihovih ergonomskih svojstava. Motivacija za izradu algoritma proizlazi iz potrebe za pouzdanijim metodama ocjenjivanja ergonomije koje uzimaju u obzir i subjektivne dojmove korisnika i objektivne ergonomske standarde. U radu je provedena analiza tržišta uredskih stolica te su identificirani ključni kriteriji za procjenu njihove ergonomije. Kriteriji su razvrstani u četiri kategorije: sjedalo, naslon za leđa, nasloni za ruke i sveukupni dojam stolice. Na temelju tih kriterija izrađen je upitnik koji omogućuje procjenu ergonomskih karakteristika stolice kroz kombinaciju subjektivne i objektivne evaluacije. Algoritam je razvijen za najčešće korištenu kategoriju uredskih stolica, uz mogućnost daljnje prilagodbe i za druge vrste. Glavni rezultat rada je sustavan pristup ocjenjivanju ergonomskih svojstava uredskih stolica koji može pomoći korisnicima u odabiru odgovarajućeg modela. Također, algoritam može poslužiti konstruktorima i dizajnerima kao smjernica za optimizaciju ergonomskih karakteristika stolica tijekom razvoja novih modela.

Abstract (english)

With an increasing number of people working in a seated position, there is a growing need for ergonomic office chairs. Consequently, the market offers a wide variety of options, but identifying the right chair can be challenging. For this reason, the aim of this paper is to develop an algorithm for the ergonomic analysis of office chairs, enabling a systematic and objective assessment of their ergonomic properties. The motivation for creating the algorithm stems from the need for more reliable evaluation methods that consider both users' subjective impressions and objective ergonomic standards. The paper includes a market analysis of office chairs and the identification of key criteria for assessing their ergonomics. These criteria are categorized into four groups: seat, backrest, armrests, and overall impression of the chair. Based on these criteria, a questionnaire was developed to evaluate the ergonomic characteristics of chairs by combining subjective and objective assessments. The algorithm was designed for the most commonly used category of office chairs, with the possibility of adaptation for other types. The main outcome of this study is a systematic approach to evaluating the ergonomic properties of office chairs, which can assist users in selecting an appropriate model. Additionally, the algorithm can serve as a guideline for designers and manufacturers in optimizing the ergonomic features of chairs during the development of new models.
