Head And Neck Support For Cabin Seat

This study aimed to improve comfort of cabin seat. Traditional cabin seats provide the user with a pillow-like head support which might force the user bending the spine curvature. In this case, spinal vertebrae can not maintain a nature cervical curve to withstand gravity, resulting in neck and shoulder compressive stress. Moreover, maintaining a fixed sitting posture for long period of time might lead to static muscular efforts, which results in muscular aches or pain. In order to provide users with a proper support for head, a three V-shape headrest was proposed with carefully designed headrest height for optimal neck posture. The three V-shape headrests provide the user with changeable head position which helps maintain neck flexibility. Most importantly, the coordination of seat back and headrest would prevent forward head carriage which is often overlooked in terms of a cause for neck pain.
