Default Strength of an Screw Eyebolt???

OK.... OK....... I THINK I SCREWED UP THE TERMINOLOGY ....... I said RAFTER,
but what I should have said was that it is the lower horizontal 2x4 of a
common TRUSS. The trusses are 24" on center. I was thinking about lagging
in a 2x6 board with lag screws across "three trusses" ..... and then screw
in my two eyebolts ....... so all the weight should be spread across the
three rafters. The problem is that the ceiling is in the garage and has
wallboard on it but I can see that the span is 24" between the trusses. A
lot of the townhouses here have wallboard ceilings on 2x4 trusses so I would
imagine they are holding up a lot of weight already with no apparent effect.
So now that I have everybody thinking about a horizontal 2x4 truss rather
than a rafter....... Is this more acceptable or even a worse idea?
-sorry for the wrong verbage.
Thanks for all previous responses..... Appreciate it!



What I have done is not to put the supporter through the 2x4 but use
hammok rings (a hammok ring is aboit 8mm steel wire and 90mm dia) and
rope round the 2x4. Three times round the 2x4 and through the ring with
6mm or 68mm polly. or nylon means that the knot has less stres and the
swing is less likly to damage the supporting roap
