Prolonged sitting in the car is widespread in our mobile society, whether due to job-related trips or leisure trips, for example, on the way to vacation. For many years, Alfmeier has produced seat comfort systems which allow an optimal adjustment to the anatomy of the vehicle's occupants with additional options.
Adjustable headrests as well as seat and back cushions are, among other things, aspects of seat comfort systems which are to be realized with as a light construction and as few components as possible. In addition to the construction, the shape and the materials of a seat, other components also impact seat comfort: a seat adjustment (electrical or mechanical), multi-contour functionality, a massage function and a lumbar support.
Seat comfort system requirements are derived from an ergonomic perspective. Ergonomics is understood as the adaptation of the working conditions to human beings. In increasingly sedentary activities, this concerns, e.g. chairs and tables, and with frequent and prolonged driving, above all, the seats.
Through an incorrectly adjusted seat, the shape of the spine of the seated person changes in the course of a day from an "S" to a "C" shape and can lead to problems, such as back pain in the lower part of the back, tension in the upper back area, as well as strain in the neck and shoulder area.
A seating comfort system corrects the angle of the pelvis thus ensuring a reduction in the pressure on the intervertebral disc. The support in the seat is also improved, especially on the sides. The use of pneumatic seat comfort systems helps to avoid the negative effect of the curved posture of the spinal column while increasing driving comfort at the same time.
