Weatherstrip assembly having a variable length shim

A weatherstrip assembly for sealing between a frame and a closure member of a vehicle, said comprising:

• a body having an exterior surface and an interior surface defining a channel with said body having a plurality of retaining lips extending from said interior surface into said channel for retaining said body to the frame, with said interior surface including a retaining lip surface and a shim surface disposed opposite one another to define sides of said channel and with said retaining lips extending from said retaining lip surface;
• a seal extending from said exterior surface for abutting and sealing the closure member;
• a locking fin having a first end and a second end with said first end of said locking fin mounted to one of said interior surface and said exterior surface and said second end of said locking fin having a first position disposed outside of said channel and having a second position disposed within said channel to at least partially dispose said locking fin within said channel with said locking fin being deflectable between said first and second positions;
• and
• a shim extending from said second end of said locking fin with said shim formed on said locking fin when said locking fin is in said first position and engaging said shim surface of said interior surface when said locking fin is in said second position to space said locking fin from said interior surface, with said retaining lips and said locking fin at least partially defining a slot having a locking fin side adjacent said locking fin and a retaining lip side adjacent said retaining lips for sandwiching the frame between said retaining lips and said locking fin within said slot;
• wherein said shim has a length, said slot has a width, and said body has a longitudinal dimension perpendicular to each of said length and said width, with said length of said shim varying along said longitudinal dimension, and said length and said width having an indirect relationship such that as said length increases along said longitudinal dimension said width correspondingly decreases and as said length decreases along said longitudinal dimension said width correspondingly increases;
• and
• wherein said locking fin extends along a majority of said shim surface to said shim when in said second position such that only said locking fin and said shim define said locking fin side of said slot for sandwiching the frame between said retaining lips and said locking fin within said slot with said locking fin and said plurality of retaining lips all directly engaging the frame.
