29 serves for the mechanical connection and the implementation of the tiltability between the headrest holding element 3 and the headrest body 2 in particular the connection part 22 fig2 shows the lower part of a first embodiment of the headrest body 2 the space 25 is in turn filled up with the filling material 23 between the cover 21 and the connection part 22 the headrest holding element 3 as well as its tiltability double arrow 33 being also indicated in fig2 the connection part 22 comprises a fastening means 26 for the cover 21 visible in the left hand part of fig2 in the right hand part of fig2 the cover 21 merely bears against a specific profile of the connection part 22 in particular against one edge 28 of the connection part 22 and or is pressed by means of a tool not shown during the production process such that in the region of the edge 28 the filling material 23 in its processing state is not able to escape or at least not to any considerable degree the space 25 is therefore also sealed at this point the edge 28 is designed such that it has a relatively small bearing surface towards the cover 21 so that merely a small force of a tool not shown in the figures is sufficient during the production of the headrest according to the invention in order to provide sealed behavior at the position of the edge 28 on the cover 21 relative to the filling material 23 in its processing state in fig3 the first embodiment of the headrest body 2 according to the invention is shown in partially.
