Given that the flimsy-looking bracket will slow the deceleration somewhat by deforming, it would take a massive frontal impact to produce 45g at the bolts. But I still don't like the look of them!
(nb this is based on the rear anchor point taking the whole of the deceleration load, which it will not do as there is also a seat-belt anchoring the lower part of the child restraint).
