Abstract

Since implementation of the new revision of ECE R14.07, there is a need to change seatbelt anchorage (SBA) design specification at center position of passenger seat from two points SBA to three points SBA. This study is conducted to investigate which shoulder seatbelt anchorage position is preferred in term of ergonomics assessment. The study focus on perceived comfort/discomfort in specific task of reaching for the seatbelt tongue between two types of SBA position. Two different types of passenger car which are fitted with two different types of SBA position at the second row of the passenger seat were chosen. The two types of SBA position involved in the study are SBA at roof panel and SBA at seatback. Outcomes of the study are determined by the level of exertion and postural analysis using the Borg RPE Scale and the Comfort Index method, respectively. Results of the Borg RPE Scale and Comfort Index agreed that SBA at roof panel is more comfortable compared to SBA at seatback. The ergonomic assessment carried out in the study had managed to identify the level of exertion and body segment that heavily affected the overall scores. Significant findings of the study help to provide value added to ergonomics design and help designers during early stage of a new vehicle development. Most importantly, ease of use and effectiveness characteristics shown by both methodologies suitable to be applied in any situation and industry. In conclusion, the findings of the study have proven that in reaching for the seatbelt tongue task, SBA at roof panel is more comfortable compared to SBA at seatback.
