Chair without fatigue from Nissan

It turns out that just sit in the car seat – it's work. The more discomfort is the seat, the more you have to work the body, the faster driver gets tired while driving.

The logic of the process is quite simple. Standard car seats force us to be in an unnatural position. While the man sitting in this position, the body straining certain muscle groups to compensate for the load. Those who had to make long road trips, both as a driver and as a passenger, could easily verify the validity of the opinions of Nissan in practice.

On inference about what is in the car seat people are in unnatural positions, Nissan engineers have pushed the study NASA conducted to study the effects on humans of weightlessness. Watching the body position of weightlessness, Nissan decided that to take the body in the absence of gravity position is the most natural for him.





In search of optimal design "chairs without fatigue" ("fatigue-free seats") for deeper studies of the concept of "neutral position" (Neutral Posture Concept) automobile Corporation has attracted specialists of the Laboratory Yamazaki from Keio University (Yamazaki Laboratory at Keio University). The main challenge for scientists was to reproduce the "neutral stance" in terms of gravity and "move" her in her car seat.

In the laboratory created for this simulator-the simulator, which used a flexible hinged backrest that provides support for the thoracic and lumbar spine, and soft cushions that reduce pressure points and more uniformly distributing the weight.

Working on finding ways to ensure the most comfortable position, Japanese scientists are constantly controlled local characteristics of the deformation of the seat back. In the course of research a new experienced chair managed to find positions when the load on the muscles was minimal over a long period of time. In this position the muscles as intensively supplied with blood, the person feels most comfortable and less tired.

The Corporation hope that in the future will be able to equip these comfortable chairs spinal support all the cars that will not only contribute to transportation safety, but will also allow passengers to feel the journey more comfortable.
