die Gewinde-Nutrolle 4· gedreht, so gleitet das Ende 3 des Rückenlehnenträgers 1 in der Gewindenute 8, wodurch das obere Ende 7 des Rückenlehnenträgers beliebig nach vorn oder hinten geschwenkt wird. Die Gewindenute 8 ist vorteilhafterweise so ausgebildet, daß diese an beiden Enden nicht aus der Rolle 4· austritt. Hierdurch ist die Anfangs- und Endstellung der Schwenkbarkeit des Rückenlehnenträgers 1 blockiert. Um jede gewünschte Stellung des Rückenlehnenträgers zu haltern, ist die Gewindesteigung der Nute mit ca. 6° festgelegt, wodurch Selbsthemmung erreicht wird.If the thread groove roller is rotated 4 ·, the end 3 of the Backrest support 1 in the threaded groove 8, whereby the upper end 7 of the backrest support arbitrarily forward or is pivoted to the rear. The threaded groove 8 is advantageously designed so that it is not at both ends exits the roller 4. This is the start and end position of the pivotability of the backrest support 1 blocked. In order to hold the backrest support in any desired position, the thread pitch of the groove is also required approx. 6 °, whereby self-locking is achieved.
