  We define Hirsch-type equations and bundles being common generalizations of
the defining equations of e.g. Hirsch-bundles, g-bundles and Kosmulski-bundles.
In this way, common properties of alle these bundles can be proved. The main
result proves basic inequalities for these bundles. They form the basis for
convergence results as well as for criteria for these bundles to be impact
bundles.
