The global demographic shift toward an aging population presents significant implications for automotive design and safety. This research addresses a critical gap in the literature by conducting a comprehensive ergonomic assessment of elderly drivers during two essential driving tasks: reverse gear maneuvers and seat belt engagement. Through a methodologically rigorous approach combining quantitative discomfort evaluations and postural analyses, this study examined a sample of 20 elderly people, a B-segment car and a strategically positioned recording equipment. The investigation revealed statistically significant patterns of discomfort concentration in the upper body regions, particularly the shoulders and cervical area, with Rapid Upper Limb Assessment (RULA) scores indicating substantial musculoskeletal risk factors. The findings demonstrate that conventional automotive configurations impose asymmetric postural stresses that are particularly problematic for elderly users due to age-related physiological changes. This research contributes to the theoretical understanding of aging-specific ergonomic requirements and provides empirical evidence supporting the necessity for adaptive design modifications to enhance safety, comfort, and continued mobility independence among the elderly population.

摘要

The global demographic shift toward an aging population presents significant implications for automotive design and safety. This research addresses a critical gap in the literature by conducting a comprehensive ergonomic assessment of elderly drivers during two essential driving tasks: reverse gear maneuvers and seat belt engagement. Through a methodologically rigorous approach combining quantitative discomfort evaluations and postural analyses, this study examined a sample of 20 elderly people, a B-segment car and a strategically positioned recording equipment. The investigation revealed statistically significant patterns of discomfort concentration in the upper body regions, particularly the shoulders and cervical area, with Rapid Upper Limb Assessment (RULA) scores indicating substantial musculoskeletal risk factors. The findings demonstrate that conventional automotive configurations impose asymmetric postural stresses that are particularly problematic for elderly users due to age-related physiological changes. This research contributes to the theoretical understanding of aging-specific ergonomic requirements and provides empirical evidence supporting the necessity for adaptive design modifications to enhance safety, comfort, and continued mobility independence among the elderly population.
