차량용 시트 조정 변수에 따른 운전자의 요추 모멘트 비교

Posture at the driver-seat interface has been used as an typical method to assess seat comfort. The driver can control seat conditions, such as height of seat, degree of seat back, and a lumbar support. This study conducted an experiment to the comparison of lumbar moment of drivers and seat condition. The lumbar moment of participants were calculated to the percentage based on ‘94 degree of seat back, high seat pan, without lumbar moment’. The highest moment is ‘94 degree of seat back, low seat pan, without lumbar moment’ and lowest moment is ‘109 degree of seat back, low seat pan, with lumbar moment’. And as the degree of seat back increase with lumbar support, the lumbar moment is lower than the others. Hence, it is supposed that the lumbar moment have relevance to the driving comfort.
