Abstract. We talk about the 1-proper spacelike hypersurfaces in the LorentzMinkowski 6-space which have at most two distinct principal curvatures. First, we show the constancy of the scalar curvature of such hypersurfaces. In the second stage, we take the constancy of ordinary mean curvature as an additional condition to get the 1-maximality of that hypersurfaces.
