对长时间驾驶任务期间的姿势进行评估，以确定新型可自由调节卡车座椅原型的人体工程学有效性。招募了 20 名参与者来进行两次 2 小时的模拟驾驶课程。使用动作捕捉、加速计和压力垫来评估姿势。还使用感知不适 (RPD) 评级和汽车座椅不适调查问卷以 15 分钟为增量监测主观不适。参与者在驾驶的第一个小时内脊柱姿势更加中立，并报告坐在原型车上时的 RPD 较低。将臀部靠背面板与可调节座板配对有助于降低平均坐压。行业标准的卡车座椅可能会导致全身姿势不良，而拟议的新型卡车座椅的人体工程学重新设计有助于改善坐姿并减少感知的不适。 实践者总结：将新型可自由调节的卡车座椅原型与行业标准座椅进行比较，以评估对长途驾驶坐姿和不适的假设改善。结果发现，原型中的可调节面板有助于促进脊柱姿势，减少坐姿压力并改善不适感。
A postural evaluation during a prolonged driving task was conducted to determine the ergonomic validity of a new freely adjustable truck seat prototype. Twenty participants were recruited to perform two 2-h simulated driving sessions. Postures were assessed using motion capture, accelerometers and pressure pads. Subjective discomfort was also monitored in 15-min increments using ratings of perceived discomfort (RPD) and the Automotive Seating Discomfort Questionnaire. Participants had a more neutral spine posture during the first hour of the drive and reported lower RPDs while sitting in the prototype. Pairing the gluteal backrest panel with the adjustable seat pan helped reduce the average sitting pressure. The industry-standard truck seat may lead to the development of poor whole body posture, and the proposed ergonomic redesign of a new truck seat helped improve sitting posture and reduce perceived discomfort.Practitioner Summary: A new freely adjustable truck seat prototype was compared to an Industry standard seat to assess hypothesised improvements to sitting posture and discomfort for long haul driving. It was found that the adjustable panels in the prototype helped promote spine posture, reduce sitting pressure and improved discomfort ratings.
