Definitions

  • the present invention relates to a lumbar support as it can be used to support the lumbar and spinal area in backrests in all types of seats, for example motor vehicle seats.
  • Known lumbar supports of the type described above comprise at least one archable support element, which is also referred to as a lordosis basket or lordosis shield and can for example consist of a wire mesh or a one-piece plastic injection molded part.
  • known lumbar supports include an adjustment mechanism by means of which the curvature of the at least one archable support element of the lumbar support can be adjusted.
  • An adjustment mechanism known from the prior art comprises a Bowden cable arrangement, the casing of the Bowden cable arrangement being supported on one end section of the archable support element, while the wire of the Bowden cable arrangement which is displaceably mounted in the casing is attached to another end section of the archable support element, so that it is moved of the wire in the sheath of the Bowden cable arrangement, the two end sections are moved towards one another to a greater or lesser extent, in order thus to adjust the curvature of the support element.
  • the adjustment of the wire in the sheath of the Bowden cable arrangement can be done either manually, for example using a handwheel, or automatically with the aid of a corresponding motor drive.
  • Lumbar supports of the type described above are used, for example, in the backrests of motor vehicle seats.
  • the lumbar supports have a multiple support function, since both the lower spine area, i.e. the lumbar or lumbar area, as well as the central spine area and the upper spine area must be adequately supported in order to reliably relieve symptoms of fatigue when sitting for long periods and possibly even damage to health avoid. For this reason, the use of lumbar supports, their curvature or Curvature can be adjusted, of the utmost importance, in order to be able to adapt the crown to the individual needs of each person. This applies not only to lumbar supports in motor vehicle seats, but also applies to applications in the backrests of seats of any kind, for example office chairs, etc.
