WHIPS in XC90, problem seats

Why do I havePlöde seats in the XC90? Who has problems with the position of the headrests in his Volvo, especially XC90, but also other models? My problem is that I always put the backrest very upright (almost 90°), and the new seats from MY 05 have a headrest directed further towards the driver. Due to this arrangement of the headrest you have no room for movement to the rear. In a rear impact this will have advantages, unfortunately it is more of a disadvantage in daily use, since I have been suffering from tension in the neck since I drove XC90 MY 05, which is already outside of “goes” or “will already lie down” Who has similar problems and already got a solution from Volvo or his friend?
