Definitions

  • the present invention relates to a chair, in particular an office chair, with a backrest with Lu Imbai matter.
  • Object of the present invention is to improve seating and ease of use of a chair. This object is achieved by a chair according to claim 1.
  • a basic idea of the invention is to arrange the lumbar support in a height-adjustable manner on a flexible guide band.
  • the arrangement on a guide band has over the known from the prior art fastening techniques of Lumbai labn the advantage that on the one hand, the position of the lumbar support can be changed in a particularly simple manner. For example, a height adjustment by simply moving is possible with a clamping bracket of the lumbar support on the guide band. On the other hand, an excessive pressure load on the back of the seated person is avoided by the flexible design of the guide band. In other words, the lumbar support relieves the pressure of the occupant, thereby significantly improving the feeling of sitting.
  • Advantageous embodiments of the invention will be explained in more detail using an exemplary embodiment with the aid of the figures. Hereby show:
  • Fig. 1 is a side view of a backrest of a
  • FIG. 2 is a perspective view of the lumbar support of FIG. 1
  • FIG. 3 is a side view of the lumbar support of FIG. 2 with a cut support body

  • the hardness of the plastic material and thus the flexibility of the guide belt 4 can be variably adjusted during its production.
  • the lumbar pillow can be variably adjusted during its production.
  • Guide band 4 may be more or less hard or soft, so that it yields more or less strongly in the pressure direction 12 when loaded by a seated.
  • the guide band 4 is connected to a backrest 13 of a
  • the backrest 13 has a central support element 14, which at its lower end mounting elements 15 for attachment to a seat member (not shown). On the support element 14 are two extending in the direction of the seat element
