  • Patent number: 8382191
    Abstract: A vehicle emergency egress system includes a transparent armor assembly disposable in a vehicle window frame, the transparent armor assembly including at least one transparent armor pane, and interiorly accessible release means, the release means being selectively operable by a vehicle occupant for effecting release of at least the one of the transparent armor panes, such release permitting shifting a respective one of the at least one transparent armor panes from the transparent armor assembly to define an egress portal. A method of forming a vehicle emergency egress system is further included.
    Type: Grant

  • Patent number: 8354921
    Abstract: A self-illuminating handle assembly for a release mechanism of an emergency egress system for a vehicle. The handle assembly includes a sensor for sensing a predetermined condition and providing a sensor signal in response thereto, and a sensor-activated switch assembly for causing the handle assembly to self-illuminate in response to the sensor signal. The sensor could be a so-called tilt sensor for sensing when the vehicle orientation is tilted beyond a threshold tilt orientation, or an acceleration sensor (accelerometer) for sensing when the vehicle has undergone an acceleration or deceleration beyond a threshold, indicative of a crash or the vehicle having been exposed to an explosion.

  • Patent number: 8333036
    Abstract: A vehicle emergency egress assembly, including a vehicle door with an opening cut out or otherwise provided, to serve as an egress portal in case of emergency when the vehicle door is difficult to open using the ordinary latching and unlatching mechanism provided for routine entrance and exit from the vehicle. The opening is cut (or otherwise provided) where a transparent armor window would ordinarily be provided, but additional portions of the door are cut out as needed to allow for egress through the opening by a vehicle occupant. A windowed plug is then provided, for releasably plugging the opening. Finally, an interiorly accessible release mechanism is provided, including one or more handles for releasing the plug from the opening. The plug includes a body portion in addition to a window portion.
