摘要

Sewing machine operators suffer from musculoskeletal problems imposed due to constrained restricted body postures. This study was conducted to investigate the effects of three design parameters (fore/aft sewing distance, sewing desk inclination and sewing desk height) of sewing workstation on postural variables and subjective experience and to develop guidelines for sewing workstation design. At a prototype of adjustable sewing workstation, ten professional sewing machine operators performed sewing task in nine different workstation arrangements. Sewing machine operators working posture and perceptions were recorded. It was shown that trunk, neck and arm postures were influenced by fore/aft sewing distance, sewing desk inclination and sewing desk height. The determinant factor for sewing machine operators' perception on the trunk and neck found to be fore/aft sewing distance, sewing desk inclination. The sewing desk height influences the arm posture significantly. Based on the results, the following guidelines were developed: (1) Fore/aft sewing distance should be adjusted to 140 mm towards the sewing operator; (2) a 10 sewing desk inclination towards sewing should be used at sewing workstations. (3) Sewing desk height should be adjusted between 762 mm and 787 mm from the ground.
