This can be done by installing the 13 instead of the otherwise required Umlenkbe- reel-up in the direction of the beat indicated below as a fixed axis 27; B designates the installation position to reach the inner designated position. The fixed axis 27 is therefore the backrest 13; C is the installation position approximately perpendicular to the vertical axis 26 and lies in the area of the pivot axis 14 within the seat part 5 in the direction of FIG. 15, while D the installation position within the seat part 15 is the longitudinal axis of the vehicle. This location represents a preferred suggests. The installation position of the retractor 21 at the position of the fixed axis is shown, although the invention of longitudinally displaceable seat rails 23 is marked with an E and is not limited to this position. Decisive for the draws, while the letter F, the installation position of the functionality of the retractor 21 is that it is mounted in an automatic device 21 at any point of the vehicle, io level, on which the vertical axis 26 indicates perpendicular, preferably on the vehicle floor.

As already shown in FIG. 1 can be seen, the roller is rotatably mounted about a pivot axis 33. The middle plate 21 by a movement of the safety seat 12 line 34 of the rod part 32 runs through the influenced: If the retractor 21 is in the position pivot axis 14 of the backrest 13 and parallel to the NEN A or B, it takes on the position indicated by the double arrows 25 fixed axis 27. The length of the rod part 31 is chosen so Ie 16, 18, 19 and 20 indicated movement sequences that the distance between its pivot axes 33 and part. The movements indicated by the double arrows 16 and 18, equal to the distance between the pivot axis 30 and the axis, act on the reel-up 21 in the position 14 is. This results in a trapezoidal shape in the following. The winder attached there also takes part in the device designated by the rod, the movement indicated by the double arrow 20 when it is pivoted. 30 of the backrest 13 in the direction of the double arrow 16 The retractor in the position D ensures that the fixed axis 27 in every position of the double arrows 18 and 20 indicated movements. kenlehne 13 is perpendicular to the vertical axis 16.
