Blocking of position is a result of pressure of an expanding sleeve jj . in holes 12 of a stable arm I . That pressure is caused by widening of expanding nibs 9 of a grip 4 as a result of movement of an element of furniture for instance an arm -rest.
  • a sleeve 1_1 rotating in holes 12 of a stable arm ⁇ meets frictional resistance and moment of a force, opposite to rotational movement arises.

  • a gap of a through groove 6 in a grip 4 decreases itself during motion and thereby, a grip 4 , with its expanding nibs does not expand a sleeve JJ. enabling it a free turn in holes 12 of a stable arm L As a result there is a possibility of a free motion of a movable arm 2 towards regulation.
  • resistance elements 16A of a stable arm 1 effect a pin j_5 which is in a recess 10 of a grip 4 causing relocation of a pin 5 to an extreme position of a recess 10 .

  • Resistance elements 16B push out a pin 15 from extreme position in a recess 10 during return of a movable arm 2 to initial position in the final stage .
  • the pin j_5_ stops to influence protruding ends 18 of a movable arm 2. This way a joint returns to initial position and regulation of position of a movable element of furniture is possibile from the begining.
