Delayed restraint release device for inflatable escape slides

摘要

A strap restrains full extension of an evacuation slide until a bag on the slide inflates to extend and unlace a cord to separate the strap coupling the restrained segments of the slide. The device is especially useful as a back-up restraint in escape slides of the dual chamber variety wherein the inflation of one but not the other of the chambers will not create sufficient pressure to break a primary restraint device employing shear pins separable by a predetermined pressure being attained in the inflatable slide chambers.
