spare part does not open

My Peugeot 307 sw car's arm bracket was broken . The black plastic part that touched the seat. I was going to search for spare parts about it but the link is broken I think I would appreciate it if you help.

the link is working, no corruption, just trying to complete all the products on the site.

I am getting this web page cannot be displayed warning. There is a problem but I do not understand

the https://www.peugeotturkiye.com/peugeot-307-sol-koltuk-kol-dayama-mekanizmasi-orj

I think this website is not used, I think there is a problem on my computer.
