I'm sorry I can't explain it any better. like I said:
Imagine two 4" x 4" metal plates, with holes in all four corners, and say four 3 " bolts between the two plates. You twist one plate clockwise and the other counter-clockwise. The bolts will twist and TILT, in sort of a spiral.
One of the 4" x 4" plates, represent the chairs base, where the bolts thread into.
The other 4" x 4" plate represents the bracket attached to the gas cylinder and legs.
The reason the bolts can pull out, is because when you twsit the two plates (in the example) in opposite directions...the 4 bolts (one in each corner) will...TILT.
The ONLY way to prevent them from tilting, is to use a rigid ...thing...that the 4 bolts all have to pass thru, that has some good thickness. Like a 2 x 8.
Where the 4 bolts pass thru the 2x8...they CAN'T tilt.
Because they can't tilt, they can't twist out of the chair base.
How can they In the metal Spacers too
Tell me in that pic how they could without some freak unicorn ghotlogic incident?
