Health, safety and comfort are at the heart of ISRI's seating development. The biological functions and needs of the human body, as well as a thorough examination of the work environment, guide our seating design. Our experts work closely in the functional areas of development, design and ergonomics to combine all the requirements of ergonomic seating.
Seating development adapted to the human body.
To meet the requirements of an ergonomically designed seat, it is important to understand the human body with its biological functions and needs. It is also necessary to carefully examine the work environment:
These are the questions we focus on so that the driver can adjust the seat in an optimal way and improve his health and well-being.
Why is movement important and how can we incorporate more of it into the driver's and passenger's daily routine?
The body needs movement to help activate its metabolism and circulation to remain attentive and reactive. The spine and its intervertebral discs need movement to ensure the exchange of nutrients, which helps keeping the spine supple, flexible and able to absorb vertical shocks. In the long-term, an unequal distribution strain along the spine, resulting from an unhealthy seating position, is an additional risk factor related to lack of movement.
This is why, as part of the project “Movement in the Workplace,” we are continually researching new seat concepts that stimulate active driver movement and stop drivers from remaining in a static posture while they are seated.
A good sitting posture is essential to stay attentive to both the control and traffic. However, it can also lead to complaints due to a permanently crooked or constant sitting posture. Consciously changing the sitting posture even while driving by adjusting the backrest or seat cushion tilt is particularly important.
It is therefore important to become familiar with the correct sitting posture.
