Definitions

  • the invention relates to a seat back of a vehicle seat with a height-adjustable headrest.
  • Object of the present invention is to provide an improved seat back of a vehicle seat with a height-adjustable headrest.
  • a seat back of a vehicle seat includes a height adjustable headrest.
  • a height adjustment mechanism of the headrest is provided, whose path is a curved path.
  • the headrest is at a height adjustment of the headrest up
  • the advantage achieved by the invention is, in particular, that a distance between a head of a person sitting on the vehicle seat and the headrest at the correct height adjustment also at People with very different seat size is largely constant. A change of a distance of the headrest to the head by a mechanical displacement of the headrest forward or backward is thus unnecessary. Such a headrest thus always has and person-independent on a perceived as pleasant positioning, at least if the headrest is largely adjusted correctly height. In addition, a risk of injury to a person using the vehicle seat is reduced in an accident.
  • An embodiment of the invention provides that the headrest on the front side has a concave surface in a vertical course.
  • the distance between the head of the person sitting on the vehicle seat and the headrest at the correct height setting is not only largely constant for people with very different seat size, but the system of correct
  • height-adjustable headrest is perceived as particularly pleasant for persons with almost any seat size.
  • Height adjustment mechanism of the headrest has a number of guides, each describing the curved path.
  • two opposing guides are provided which describe the same curved path.
  • Such a height adjustment mechanism is mechanically comparatively simple and comparatively inexpensive to produce.
  • the shape of the guides and thus the shape of the curved paths are easy to fix.
  • the height adjustment mechanism of the headrest preferably comprises a first transverse strut and a second transverse strut, which are each firmly connected to the headrest.
  • the cross struts are particularly preferably at least partially within the headrest, wherein the ends of the cross struts are vertically displaceable in the number of guides, in particular in two guides, are arranged.
  • Such a height adjustment mechanism is mechanically simple, allows easy height adjustment and high mechanical strength, so that a risk of injury to a person using the vehicle seat is reduced in an accident.
