rubber protector sheets?

[enobmort42]

i'm not really familiar with the terminology, so bear with me on this!

does anyone know where i can find a rubber sheet or something similar to put on the pillar by the seats to keep the seatbelt from scratching it all up? i want it to have the same function as, say, a computer screen protector, but i want it to feel more like a soft plastic/hard rubber so it kind of dampens the noise when it hits, too.

i wish i had pictures to help describe what i'm talking about, but i'm not anywhere near the car at the moment..

any help is great. thanks!
