  Elastic backrest for chairs or the like.



   The invention relates to an elastic backrest for chairs or the like with a support plate which forms the support and is held by springs, in which the support plate is held in a plane in front of the backrest frame by leaf springs, possibly in conjunction with tension springs, so that when loaded the support plate forms a trough which hugs the body shape.



   In the drawing, the subject matter of the invention is shown diagrammatically on a chair in two exemplary embodiments. It denotes: a the support frame, b the support plate, c the leaf springs, which, if necessary in conjunction with tension springs d, hold the support plate in a plane in front of the support frame a.
