I edited this question more than any of my questions before, please feel free to view old versions. The overhaul of the question was approved in principle by a moderator. I did also add an answer with one other solution I thought about, but that is still only a concept and I would love some opinions.
Objective
I am looking for a way to protect my child's face from rain and wind while in a child bike seat. I'm not a scientist but she gets cold easily and my parental instinct is that even partial cover/protection of the face would reduce wind-chill noticeably. It's for getting my child to school, just a steady 15-20 minute ride but we live in England.
There seem to be no purpose-made products readily available on the market (except from an amazon seller who doesn't look trustworthy). And product recommendation is, controversially to say the least, not allowed on stack exchange (but I'd love a link if they exist).
First thing I could think of
Convert a Rain cover from a "rucksack" child carrier to attach it to a bike seat
Has anyone ever done this? I would like to minimize damage/modification to either product. How can I attach one to another? Do I need to 3d print some fittings?
Factors I need to balance
Usability, breathability, crashworthiness, constructability, wind resistance (from being blown away or into child's face), entanglement ...
Options discarded
Naturally one way would be to use a trailer but I am very reluctant to do this:
- I don't really have room to store it,
- there are chicanes on our route to deter mopeds/motorcycles etc.
My child is too big for a Thule RideAlong Mini Windscreen - it's a product intended for a seat for smaller children, sat between the rider's arms.
Any other alternative ideas will be welcome.
