In addition, the setting of the braking force can, under certain circumstances, also be influenced by this arrangement.

Further possibilities for adjusting the braking force arising SiCl characterized in that the bearing and ¹ pivot substantially in the same plane, in particular midplane of the wearer, and in that the axis of the pivot and the Veruchieberieh averaging of the bearing at an acute angle to each other arrange L are.

The La good ¹ Ü has a central bore lü for a shaft 17, which on the suffer side protrudes over the broad sides of the bearing box 32, with] on the ends of each of a roller 18 or 19 is placed. The hollows each have an annular flange 20, 21 which is directed towards the bearing side. ] in the rest of the storage box 32 in the area of the lower end face on both sides circularly curved brake shoes 22, which each cover the outer surfaces of the hubs 34, 35 of the rollers 18 and 19 and Lei m, loaded seating furniture by the action of the spring 9 against these outer surfaces are pressed. The existing braking surface is dimensioned in such a way that, taking into account the number of furniture castors present on the seating furniture, the unloaded seating furniture has a resistance of 1.2 to 2.4 kg to displacement. It is also taken into account that in the illustrated embodiment, the axis 36 of the pivot 4 is arranged at an angle to the verse direction of the bearing 8 which coincides with the center line 37. Furthermore is. takes into account that the spring 9, which is a helical spring in the illustrated embodiment, which is held and guided in a continuous recess 38 of the housing 33, this being made of a flexible, corrosion-resistant plastic material bes Leht.

Otherwise it follows from Fig. 3 that the housing.; E 33 Has guide belts 39, in the associated guide strips MO on the side walls 13, 14 of the recess 7 in the area of the housing 33 engage so that the housing 33 and thus the spring 9 is held in the desired manner. Furthermore the arrangement is made so that the outsides drs housing 33 complete with the outer sides of the storage box 32.
