Holder for roof of Hollywood swing

My parents have a house in the country and a large garden, we live in a region with a lot of wind, unfortunately, strong gusts of wind repeatedly destroyed the roof of the Hollywood swing, more precisely tore off the holder. 

At the first defect, the manufacturer still replaced the component free of charge - but this should also not last long.
So my father, retired engineer, asked me for an idea and we looked at the part together.
Removing the roof before any wind would have been far too costly.
There were definite weak points on the part in our opinion - it always broke in the same place.
So I took the part home and thought of a new solution, in the first step, I digitized the part completely as it was, so that the roof could be mounted again, I first simply printed out the original part.

However, this part also broke in stronger gusts of wind - another solution was needed. So that not all the energy always goes into the whole part, we mounted the roof not with screws but with reusable cable ties - the mounting and dismounting was thus much easier. Now the part held for some time, but broke again.
I then made the upper part of TPU, so everything is much more elastic and the roof has more room to move, it now breaks at most a cable tie, but not the part itself.
 

Here are some technical data and printing instructions:

The swing was purchased at Jysk A/S, a Danish retail chain. Unfortunately unbranded - I think there are many outlets.
The lower part was printed from PLA, the upper part from TPU, both are connected with long M5 screws.
The lower part has to be printed solid, the TPU part with maybe 50-60% filling or even solid - depending on shore hardness. No support material is needed for booth parts.
