Abstract
A secondary release arrangement for a releasable restraint may comprise a flexible member in operable communication with a strap attached to the releasable restraint configured to release the strap from the releasable restraint in response to a tensile force in the flexible member exceeding a selected threshold. In various embodiments, the secondary release arrangement may be configured to allow deployment of an evacuation system in the event of the releasable restraint failing to release.
Claims20
A secondary release arrangement for an inflatable evacuation system comprising:
- a releasable restraint;
- a strap coupled to the releasable restraint via a thread;
- a flexible member coupled to the thread, the flexible member is configured to break the thread to release the strap from the releasable restraint in response to a tensile force in the flexible member exceeding a selected threshold.
An evacuation system, comprising:
- an evacuation slide configured to be deployed from an aircraft, comprising a head end and a toe end;
- a releasable restraint having a first end coupled to the evacuation slide via a first strap and having a second end coupled to the evacuation slide via a second strap, wherein the first strap is coupled to the first end of the releasable restraint via a thread;
- and
- a secondary release arrangement comprising:
- a flexible member coupled to the thread, the flexible member is configured to break the thread to release the strap from the releasable restraint in response to a tensile force in the flexible member exceeding a selected threshold.
A method for manufacturing an evacuation slide, comprising:
- disposing a first strap to extend between a releasable restraint and the evacuation slide;
- coupling the first strap to the releasable restraint via a thread;
- disposing a flexible member between a head end of the evacuation slide and the thread;
- and
- coupling the flexible member to the thread, wherein the flexible member is configured to break the thread to release the first strap from the releasable restraint in response to a tensile force in the flexible member exceeding a selected threshold.
