The plastic adjuster knob has three plastic lips that locate behind the three metal lugs. You need to get a small flat screwdriver in behind the plastic wheel and lever out one of the clips, once one clip is out the other two will follow. It is a matter of pulling quite hard on the wheel while fiddling in the back with the screwdriver. It is impossible to see what you are doing, it is just trial and error.To refit: it just needs the plastic wheel pushing back on until the clips locate behind the metal lugs.

The tilt lever needs to come off and in fact that was the only thing I broke as I could not see how it came apart. The little plastic handle was still available from Volvo last spring, so I put a new one on.

Again if you look at the stripped seat photo you can see the metal lever sticking out the side. There is a little tab on the side of the metal lever that locates in a little recess in the plastic handle. The handle just pushes on until the tab locates. To remove the handle it needs a small flat screwdriver to ease the plastic away from the tab while pulling the plastic handle off. The tab is on the vertical face, but I cannot remember whether it is back or front side. Once the plastic handle is off the surround trim is held on with one screw, undo that and the trim comes away.

Other things to note: The back rest upholstery is clipped together at the bottom with a special plastic closer. Just start to prise apart at one end and it will come apart a bit like a zip fastener. Once you have the bottom of the cover open there is a solid plastic panel inside a pocket that forms part of the backrest cover - this just pulls out and allows the cover to be peeled upwards to get access further up the seat. Once you have the covers exposed some way up the backrest you will have access to the elastic anchors holding the back of the backrest taught. I used pin nosed pliers to release the hooks and then the cover can be peeled up whilst releasing the hog rings on the front.

One point to note when re-assembling: attach the upholstery in the same places as the hog rings. Don't worry about getting everything spot on with no wrinkles as the upholstery is self adjusting - once the cover is back in position.

The seat cushion is easy compared with the back rest. Hope this helps.
