  • a preferred embodiment according to the invention consists in the fact that the front housing wall has a central section fixed to the housing and that a pivoting wing is pivotably articulated on both sides of the section fixed to the housing.
  • a simple design of the swivel articulation points is created in that the swivel articulation point of each swivel wing is formed by a plastic film hinge.
  • each swivel wing forms a collar on its outer wall, which overlaps an adjacent edge region of the cushion carrier and thereby conceals the cavity of the cushion carrier from the outside in every swivel position of the swivel wing ,
  • the collar which can at the same time serve to hold the upholstery forming the head contact surface, can be guided around the entire circumference of the headrest except for the points adjacent to the upright pivot axes.
  • Cavity is arranged inside between the central region of the front housing wall and the rear housing wall of the upholstery support, a fixed, in particular approximately box-like, support region with the front housing wall and / or the rear housing wall, and that the support region serves to fasten the upholstery support to the at least one support rod.
  • the box-like support area to a certain extent represents the central core of the upholstery support.
  • This central core which serves to connect the at least one support rod and possibly also to tilt the upholstery support, can always be of identical design in different, for example differently wide, but otherwise generic headrest models.
  • the support area can either be fastened to the rear housing wall or to the front housing wall, in particular be integrally connected to the respective housing wall.
  • the invention provides that the support area is divided along a plane approximately parallel to the rear and front housing wall, and that the rear part of the support area on the rear housing wall and the front part of the support area on the front housing wall, expediently in each case by a material connection , is attached.
  • a material connection expediently in each case by a material connection.
  • Such a preferred embodiment allows a technically favorable insertion installation of the support rod arrangement which also includes the tilting position. This is especially the case when the support rod arrangement comprises a U-shaped support rod bracket with a friction clamp held non-rotatably in the support region.
