In my life I have now already mounted some seats.
This one of Wenco but suggests when attaching the last straw!
This new mounting with rubber plugs (?) May not work because the lid is still slowed. The mechanical stress is so much bigger than a normal ejection seat.
Anyway, it does not take long and the lid has shaken loose itself. So it will be rebuilt and besfestigt in the normal way!
Addendum dated 09.02.2013:
After some ups and downs this Super seat called Absenkautomatic now has given up her mind !!!
It is an absolute impudence of the company Wenko offer (brand?), Such scrap to customers for 50 euros. Each discount you can get the offer you quality for 20 euros ....
One may even try now to complain! In my case hopeless ...
