The concept of introducing movement in automotive seating was investigated. Three seat conditions, a control (no movement) and two movement conditions (fore-aft and cushion-backrest) were compared. Movement was introduced at a fixed speed, slow, smooth and within a small range. Ten participants took part in a 60 min 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.
研究了在汽车座椅中引入运动的概念。比较了三种座椅情况，一种是对照（无运动），两种是运动情况（前后和座垫靠背）。运动以固定速度、缓慢、平稳且在小范围内进行。十位参与者在每种情况下进行了 60 分钟的模拟驾驶——单盲、重复测量和平衡顺序。收集了六个身体区域的不适评分以及整体不适和幸福感问卷。还记录了驾驶员姿势和座椅抖动和移动（SFMs）。在两种座椅运动情况下，整体和颈部、肩部、下背部、臀部和脚踝的不适评分都有下降的趋势。运动时的幸福感评分也更好。在 60 分钟时，臀部不适有明显差异——座椅运动时不适感较小。随着驾驶时间的增加，整体不适和 SFMs 频率增加。总的来说，被动座椅运动受到了好评。
