Actually I'll correct myself, the armrest itself pulls down and folds up as normal but from memory I don't think there is a 'through' loading faculty for ski's etc, but I can't check cos the car is in Norwich and I'm in south Australia!!
I have that style on my 210.
I cut a piece of thin hard plastic a washed milk container I think.
Long and straight as possible with a cut out to give a hook shape then slid it in and found some paper had jammed it.
