An emergency egress system for a locus that is exposed to light in non-emergency use and susceptible to interruption or termination of light in emergency circumstances. The emergency egress system comprises a fibrous web deployed in the locus, wherein the fibrous web has photoluminescent fiber incorporated therein in sufficient amount and distribution to illuminate the web or predetermined portions thereof during the interruption or termination of light in emergency circumstances, and subsequent to light exposure thereof.

A system and method that helps evacuees exit a building in the event of an emergency such as a smoke event, a fire, an earthquake, a security breach, and/or the presence of unsafe levels of hazardous gasses, using linear illuminators parallel to and near the floor of an interior room or hallway to provide floor-level identification and illumination of the exit route to be used in the event of such an emergency, with some linear illuminators having directional aspects along hallways to lead evacuees toward an exit, and other illuminators outlining the perimeter of windows or doors that are safe to exit through, the illuminators normally being hardly noticeable but having controllers and energizers linked to the alarm and security systems of hospitals, hotels, residences and other occupied building structures to light up the planned exit route when emergency conditions are detected.

An emergency exit door lock system configured to cooperate with a door hinged in a door frame for sensing when a person attempts to open the door, and for allowing the door to open after a subsequent delay. The system comprises an electromagnet affixable to a door frame for electromagnetically attracting an armature resiliently affixed at a variable armature separation distance to an armature mounting device, the device being affixable to the door. A proximity sensor including an analog Hall Effect device is mountable to the frame for detecting movement of the door away from a closed position. A controller, such as a micro-controller, receives a signal from the sensor and causes an alarm as a function of the signal. The signal is indicative of the armature separation distance, the controller being calibrate-able to provide a door alarm signal and door opening signal at any desired value of the armature separation distance.

A seating arrangement in an aircraft passenger cabin includes rows of seats, one behind another at a prescribed seat pitch. A wider transverse aisle is formed between successive seat rows at a normal exit or an emergency exit. At least one seat row bordering on and facing the transverse aisle is equipped with foldable passenger seats that each have an upwardly tiltable seat bottom and armrests. By tilting up the seat bottom and the armrests, an enlarged width of the transverse aisle is provided in the event of an emergency evacuation. In normal operation, the prescribed transverse aisle width does not need to be maintained, i.e. can be reduced, so the seat bottom and armrests are tilted down into the normal-use position for a passenger to be seated on the seat. Thereby the seat pitch of this seat row can be reduced and the total seating capacity can be increased.

An emergency evacuation slide system includes a control valve having a normally-open vent that closes after a predetermined period of time calculated to vent excess inflation gas produced by the gas generator. In operation, in the event of an aircraft emergency exit door being opened in the “armed” condition, the primary valve member of the control valve is opened allowing inflation gas to flow into the valve chamber. A portion of the gas entering the chamber is vented through the normally-open vent. After a predetermined period of time calculated to be sufficient to vent the excess inflation gas, the normally-open valve is closed to divert 100% of the remaining inflation gas into the evacuation slide.

The ramp (16) is located in its operational position completely above the coupler (26) of the rail vehicle. Moreover, the ramp (16) is provided with a foldable or telescopic ladder (21). The escape device allows both a train-to-train and a train-to-track evacuation of passengers.

The present invention discloses a secondary barrier system with the same focus on public safety as well as the security of the secure area by providing both an extended secure area for the primary barrier, together with the functionality of an emergency exit, meaning it can be opened without much effort by the general non-skilled public in the event of emergency. The combination of secured barrier (to protect the primary barrier) and quick opening (in an event of emergency) of the present invention is accomplished by a special latch system. The special latch system in the present invention secondary barrier system is designed to require even the skilled intruder at least a few seconds to open, while allowing the non-skilled public only less than a minute. The less-than-a-minute opening time by the non-skilled public is acceptable for an emergency exit, while the more-than-a-few-second delay time is adequate for the close and securing of the primary barrier against an intruder breach. The present invention secondary barrier is well suitable for aircraft where public safety such as emergency exit is of comparable importance as security.

The invention provides a method for intuitively guiding a human to a reference location, such as an emergency exit, with a lighting system comprising a plurality of light sources along a pathway to the reference location. The lights shine with an intensity dependent upon the distance to the reference location, in particular the intensity of the light increases with decreasing distance to the reference location. The location of the emergency can be determined through emergency sensors, so that the intensity of the light sources is then controlled to lead away from the danger to the nearest safe exit.

A locking system wherein the latch is rotatable to provide either a first beveled surface for use as a ramp in latching or a second beveled surface for use as a ramp in unlatching. An entire latch module may be rotated about its axis by a rotary solenoid to achieve this function, and the first and second ramping surfaces are physically the same surface repositioned by rotation 180°. Alternatively, a releasable latch has a beveled surface for engaging a striker plate during bolt entry and a non-beveled surface for locking. The latch is pivotable to allow the non-beveled surface to become the beveled ramp for unlocking. The releasably pivotable latch mechanism may be used with a deadlock. The mechanism is readily incorporated into a rim exit device for releasably securing a door such as an emergency exit and may be actuated either electrically or manually.

Passenger seats having improved comfort emergency egress solutions for mini suites or other types of passenger seats that have a privacy screen, wall, or sliding door that divides the passenger seat from the aisle area or other common area. Specific embodiments find particular use on-board passenger transportation vehicles, such as aircraft, where comfort and privacy must be balanced with safety and federal regulations.

Emergency egress systems carry multiple riders simultaneously accessing a zip line (catenary) from higher, accessible, working locations to lower, safer areas in a marine environment. Hangers above the track line suspend trolleys to avoid weighting the catenary unduly at the high end, which might otherwise alter (reduce) clearance distances and safety of riders above a launch platform (deck). Catenary shape is controlled against approaching the launch deck by sequencing the release from the hangers of each trolley to roll along the catenary with its own rider. Track line systems installed may be left undeployed indefinitely. Deployment of a track line will typically be fully effected at the time of egress, adding time but eliminating permanent obstructions that would result if a permanent deployment of track lines were undertaken. Terminal ends are anchored and configured to accommodate workers arriving after escape.
