Letting f be the InterpolatingFunction object then
f/.InterpolatingFunction[{a_},__]:>a
does what you want.
A simple way to solve this type of problem is to look at Mathematica's output in InputForm. That will show you the structure of the output and usually enable you to see what pattern matching rule is needed to extract the desired portion.
