Indoor Swinging Chair...from truss?

[ZoeHillo]

We hung a suspended chair from our attic truss, and are wondering if that was wise.
We drilled 3/16 pilot holes and used (2) 1/4 lag screws to hold a D-ring and plate vertically, against the indoor ceiling, so the weight of the swing is held by the integrity of the lag screws thread's hold in the wood.
We reinforced the actual bottom cord of the truss with 2x4's running from the bottom cord to the angled rafter, enlisting the entire web of the truss in supporting the weight of the swing and a 225 lb man.
We're worried about the fact that the chair can swing and swivel, and wonders if the lags will eventually unseat themselves (they have a 1/8 deep thread).
What do you think? Take it down and use something like a LedgerLOK with deeper thread, or will the lags work fine?


Thanks!

Indeed, nealtw gave a very wonderful idea, or rather a solution to the problem. As one option, I would also find a piece of the pole, and cut it if necessary, and place it between two trusses. Well, of course, you need to fasten them so that they cannot weaken. Another solution I found was to use instead of a bolt with a washer, a part from a baby bouncer walker, namely these types https://newbabycentral.com/best-baby-bouncer-walker-of-2021/. They are very good and easy to fasten, and it will be easy to make a triangle of four trusses.
