Engineering movement into automotive seating: Does the driver feel more comfortable and refreshed?

Abstract

The concept of introducing movement in automotive seating was investigated. Three seat conditions, a control (no movement) and two movement conditions (fore-aft and cushionbackrest) were compared. Movement was introduced at a fixed speed, slow, smooth and within a small range. Ten participants took part in a 60 minute simulated drive for each condition-single blind, repeated measures, and balanced order. Discomfort ratings were collected for six body areas and overall discomfort, together with a wellbeing questionnaire. Driver posture and Seat Fidgets and Movements (SFMs) were captured. There was a trend for lower ratings of discomfort, overall and in the neck, shoulders, lower back, buttocks, and ankles with both seat movement conditions. Wellbeing ratings were also better with movement. Significant differences were found at minute 60 for buttock discomfort-less discomfort with seat movement. Overall discomfort and SFMs frequency increased with time driving. Generally, passive seat movement was well received.

Differences between the Anthropometric Measurements of Serbian and Libyan Male Passenger Car Drivers

“…e importance of anthropometric measurements is highlighted by the fact that driving for extended periods of time inevitably leads to musculoskeletal symptoms and is associated with disorders of the spine, deep vein thrombosis, and similar problems [38][39][40]. Restricted postures, repetitive movements, vibration, continuous attention to the road, and stress are the suspected risk factors for various disorders in drivers [39].…”

Effect of Tire Dynamic Characteristics on Vibration Load of the Operator's Workplace

“…Давление воздуха в шинах коммунальной машины на базе МТЗ-80, рекомендуемое производителем, установленное ГОСТ 7463-2003, а также указанное в руководстве по эксплуатации, корректно варьировать в пределах: для задних колес 0,1-0,18 МПа, для передних колес 0,12-0,26 МПа [4,17,18]. Такие значения давления соответствуют C i заднего колеса 2,7•10 5 … 3,6•10 5 Н/м, переднего колеса 29•10 5 …4,6•10 5 Н/м [18,19].…”

“…4) и в шинах колес заднего моста (рис. 5) в пределах, в которых может сохраняться продолжительность срока службы шин, позволяет снизить величину динамических воздействий на полу кабины и раме машины [19,20]. Изменение величины динамических воздействий на кресле оператора при этом несущественно.…”

Exploring Seat Movement While Driving - What Do Drivers Think?

“…As an example, Veen et al [6] investigated a seat movement system in which the backrest moved 1.5° backwards and the seat cushion 1° up and down (and back to the starting position) and concluded it had a beneficial effect on the wellbeing of the drivers. An experimental study by the author has shown that there was less reported discomfort with seat movement while driving compared to no seat movement [7]. Using the methods, driving rig and movement conditions standardized from previous studies [7,8], this paper reports on research conducted to understand in more detail the drivers' experience of the seat movement concept.…”
