ABSTRACT:
A seat for a vehicle, aircraft or the like includes a seat part and a backrest whereby the backrest is provided with an integrated headrest. In order that, on the one hand, the area of the cervical spinal column-lordosis of the respective seat user is effectively supported during the driving operation and, on the other, injuries of the cervical spinal column are at least reduced in case of an impact, a continuously changeable vacuum cushion is arranged at the backrest within the area of the headrest which is adapted to be individually matched to the cervical vertebrae column-lordosis of the respective seat user by means of an extraction pump and at least one valve.
