We look for sufficient conditions such that the scalar curvature, Ricci andKretchmann scalars be bounded in Hyperextended Scalar Tensor theory for Bianchimodels. We find classes of gravitation functions and Brans-Dicke couplingfunctions such that the theories thus defined avoid the singularity. We compareour results with these found by Rama in the framework of the Generalised ScalarTensor theory for the FLRW models.Comment: 13 page
