Diseño de silla ergonómica para el laboratorio de computación de un instituto tecnológico de la ciudad de Loja

Abstract

Abstract: The present investigation was descriptive, focused on 39 students of the sixth cycle of the "Sudamericano Technological Institute , who are users of the computer lab, in which their anthropometric measurements were recorded for the proper design of the ergonomic chair. The applied methodology was based on five phases, The first one was to apply the Nordic Questionnaire to know the musculoskeletal disorders they present, the second phase was to measure the study stations (table and chair), the third phasewas to record the anthropometric measurements, the fourth phase was to statistically analyze the anthropometric measurements and the fifth phase was to design the ergonomic chair.Of the 100% of the students surveyed, 92% expressed that they have felt discomfort in the neck, and on average 18% of the students have gone to the doctor where they received treatment for some type of help. For the ergonomic chair design proposal, it worked with the P50 & P90 percentiles, and three global segments were considered, which are: supporting element, the seat-armrest element, and the back support element.
