Zusammenfassung:An apparatus (10) includes structure (96, 98) for sensing and responding to vehicle acceleration by providing an electrical actuation signal. The apparatus further includes a blocking device (36) which is responsive to the electrical actuation signal to block at least a portion of a vehicle seat frame (18) from moving under the influence of vehicle crash forces upon the occurrence of the crash-indicating acceleration. The sensing and responding structure (96, 98) is operative so as not to provide the electrical actuation signal if the crash-indicating acceleration is below or within a specified range of intermediate levels that indicate crashes having corresponding intermediate levels of severity. The sensing and responding structure (96, 98) is further operative to provide the electrical actuation signal if the crash-indicating acceleration has a relatively high level above the specified range of intermediate levels.
