First Claim
Patent Images
1. An inflatable evacuation object selected from the group consisting of a slide and a raft, wherein the inflatable evacuation object is capable of being folded, at least in part, prior to deployment and comprises:
- a. a first section;
b. a second section capable of being folded relative to the first section prior to deployment;
c. a third section capable of being folded relative to the second section prior to deployment, the second section contiguous with and directly connected between the first and third sections;
d. a first restraint assembly (i) contacting each of the first, second, and third sections, (ii) comprising a component having length, and (iii) configured to release as a function of an angle to which the second section has unfolded relative to the first section during deployment of the inflatable evacuation object, based at least in part on the length of the component; and
e. a second restraint assembly (i) contacting each of the first and second sections and (ii) configured to release prior to release of the first restraint assembly during deployment of the inflatable evacuation object.

Abstract
Detailed are restraints intended principally (but not necessarily exclusively) for inflatable evacuation slides or rafts. At least one such restraint may be designed to release based on geometric shape of an object (such as a slide) rather than merely as a function of its inflation pressure or length. One version of this type of restraint includes a connector pin attached to a cord, with tensioning of the cord eventually retracting the pin to effect release of the restraint.
