Passenger Seat Belt Issue

[nsxt2000]

Lately there has been a problem with the seat belt on the passenger side where it progressively tightens up while driving. This seemed more prevelent over the last several days while driving to NSXPO. None of my other three NSX's ever did this and I was wondering if any others are experiencing the problem?

If so, is there an easy fix?

Thanks for any input.
