Abstract
Ring pellets for gas generators exhibit optimum reaction rates by having configurations which optimize such rates. The pellet has a central ignition duct; from the latter, outlet channels extend radially toward a rim of the pellet. Specific embodiments contain, on the topside and underside of the pellets, either conical recesses or annular channels or both. The pellets preferably exhibit a proportion of surface area/unit weight of from 4 to 7 cm.sup.2 /g, which can be set by variation of the channels and, respectively, of the recesses to obtain a desired value. The higher this value, the greater the reaction rate. The ring pellets are especially well suited for airbag generators which must display differently high reaction rates on the driver's side and on the front-seat passenger's side, and which are to exhibit at the same time a high breaking and abrasion stability.
