Abstract
Let I n be the class of all signed involutions in the hyperoctahedral group script B signn and let I n (T) be the set of involutions in I n which avoid a set T of signed patterns. In this paper, we complete a further case of the program initiated by Simion and Schmidt [6] by enumerating I n (T) for all signed permutations T ⊂ B2 .
