Volvo ipad headrest holder

This is a design to suit a Volvo,due to the way the seat is made.
The clamp (Ipad holder) is custom to the cover on my daughters Ipad. The clamp can be changed (redesigned) to suit other tablet covers, the rest of the holder should fit Volvo car's headrest in this model seat, like in the photos. I used M5 and M6 nuts and bolts.I used Button head bolts as not to damage the leather seats.
