An impact or recoil member possessing a plurality of gas cushions which are arranged within each other, and which are activatable in sequence in response to a triggering sensor. A comparatively hard assumption of a load by the outer gas cushion is permitted up to a pressure rise beyond its bursting limit; with at least one inner gas cushion which is designed for the assumption of the residual energy of the mass which is to be caught under a hard or stiff spring characteristic. The individual gas cushions are activated staggered in time from the outside towards the inside over a period of time from a triggering apparatus which is centrally provided for all gas cushions either in or behind the mounting support for the inflation of the still folded-in cushion casings in a specified time sequence, whereby the actuation of the triggering apparatus is implemented through the triggering or tripping sensor which is correlated with the loading scenario.
