Abstract:
A cushioning device connectable between two relatively moveable structures to cushion movement between the structures, said device comprising:first and second shiftably interconnected components,said first component being connectable to one of the structures for movement therewith, andsaid second component being connectable to the other ofthe structures for movement therewith,said components being threadably intercoupled so that relative shifting of the components requires a screwing or unscrewing action that serves to cushion movement between the structures,said first component including a first threaded element, and said second component including a second threaded element,said first and second elements being aligned along a common thread axis and prevented from rotating relative to one another; anda third threaded element threadably connected between the first and second threaded elements such that the third element rotates as the components shift relative to one another.
