Hartal concertina door blind, how to restring ?

[SandraL]

The strings are frayed and need replacing.
But how does one remove the blind.
Its on a 2013 hymer, the door is a Hartal with the inner skin bonded, I think , to the insulation.
I have managed to unclip the upper part of the blind. See photo of the clips.
Lower end has clips just visible i photo.
Side channels appear glued to inner skin.

Need to remove lower end completely to restring,. Help please!
image 1 is top of window showing the clips that held the top bar
image 2 is looking down at bottom of blind, you can just see the clips similar to top, but could not release bottom.
image 3 shows bottom area of window
image 4 shows top rail that unclipped, it has the sliding plate with grub screw to tension the strings.

Thanks for looking, I hope that someone has already got the answer...

This doesn't fully answer your question, but we had the full blind replaced under warranty on a 2018 door, because the cord broke. I didn't see it done, but when asked, the technician said - "it just pops out, and the new one clips in". No mention of it being bonded, and no dismantling of the door.

Thanks for takng time to reply. At least I know we ar on right track. Top has popped out, so half way there.
Still struggling with the bottom half removal.

I've just had the cord go on my 2018 Auto Sleeper. When I took it to the dealer for initial inspection, the technician explained that replacement was a 'pop out' job - just a matter of a lot of bad language. It's booked in tomorrow fro replacement and the dealer is only allowing an hour so it can't be a major job.
Famous last words!

Ok, blind now out. Yes the top and bottom are just clipped in.
But the side channel is fixed with double sided tape. This needs prising off first as it sits in the bottom channel of the blind.
Only one side needs to come out.
Take care not to bend the channel too much as would be easy to put a crease in it
The bottom can then be unclipped.
The string had broken. The part you move has plastic end cap each end which string goes through and on to the top. String had worn through the plastic creating sharp edge. Inserted an empty pop rivet, ie removed pin and champhered the hole. Just placed in, the string runs through it so should not fray.
Yet to replace but looking good.
The clips on the blind in picture need to be screwed onto the door first, then the blind clips in.
