Definitions

  • This invention relates to a seat particularly for motor vehicles. It is generally known that extended periods of driving bring about fatigue symptoms resulting from spinal troubles. Such spinal troubles are known to occur after any extended period in a sitting position and are generally caused by two factors:
  • the interarticular disks are cushion-like pliable structures of a fibrous and cartilaginous nature disposed between individual vertebrae. As these disks do not contain any blood vessels, they are dependent on humoral blood supply, as far as admitted by the permeability of the tissue. This humoral blood supply can be considerably improved by changes in the pressure load, i.e. by a kind of pumping effect caused by movements particularly of the spinal column.
  • the invention provides a seat comprising devices for causing the seat to perform movements, and thus, deformations, at certain time intervals so as to automatically bring about changes of the sitting position. This results in the advantage that the seat transmits a fatigue-reducing movement at certain time intervals to body portions affected by the sitting position, without the aid of the seat occupant.
  • the seat is provided with a shoulder strap for retaining the upper part of the body and pulling it back against the back of the seat, and a device for producing a forward curvature of the back-rest at the height of the lumbar region of the spinal column.
  • a shoulder strap for retaining the upper part of the body and pulling it back against the back of the seat
  • a device for producing a forward curvature of the back-rest at the height of the lumbar region of the spinal column it is particularly advantageous if the backwards pulling action of the straps and the forward-arching of the back rest are coordinated in a certain manner, specifically, if the movements of the two devices occur simultaneously.
  • This leads to an expansion and compression of the interarticulate disks resulting in a pumping action which has particularly beneficial effects on the turgor, i.e. the interior pressure and the strength of these tissues which in many motorists already show signs of damage.
  • a mild massage of the back muscles effective to counteract fatigue is particularly beneficial effects on the turgor, i.e
  • the shoulder straps are preferably designed as suspender straps extending vertically or even slightly divergent downwards from the shoulders, so that they do 'not interfere with breathing or with the female breast.
  • 0 pants spinal column there may be provided a further device at the back rest between the shoulder straps for urging the thoracic spinal column forwards at certain time intervals. This results in an additional direction of movement in a different plane.
