Patent number: 11428507Abstract: A blast-resistant escape window for an armored combat ground vehicle has a cassette which fits within, and closes, a though-opening in a frame of a windscreen. Two releasable lever-operated locking mechanisms for releasably locking the cassette in the through-opening are mounted on the windscreen at opposite sides of the through-opening. The cassette can to be pushed out of the through-opening when the locking mechanisms have been operated to release the cassette from being locked to the windscreen, thereby providing an alternative exit for personnel in the vehicle.Type: GrantFiled: April 10, 2020Date of Patent: August 30, 2022Assignee: Navistar Defense, LLCInventors: James G. Rasico, John A. Green, Anthony S. Beggs, Louis A. Carnevale, Gordon J. Wolverton, Craig A. Newman, David M. Gerst, Dale S. Norman, Jeffrey M. Fsadni

Patent number: 9562750Abstract: Blast absorbing structures and system for use in absorbing blast forces exerted on a floor of a personnel cabin of a vehicle, are disclosed. The blast absorbing flexing structure comprises a bottom section forming a floor of the cabin, a first side section and opposing second side section, each side section extending from the bottom section and including a plurality of steps along a length of the second side section. The steps flex in response to a blast force. In another embodiment, the blast absorbing expanding structure comprises a force abatement device forming a floor of the cabin, a cover plate having a plurality of slots arranged around a perimeter of the plate. The cover plate is movable between a neutral position and a blast force position to diminish the blast forces prior to the blast forces to reaching an occupant of the cabin.Type: GrantFiled: April 8, 2015Date of Patent: February 7, 2017Assignee: International Truck Intellectual Property Company, LLCInventors: James G. Rasico, Gordon J. Wolverton, Paul R. Pasternak, Timothy Oselett, Craig Alan Newman, David M. Gerst, Jeff Mears, Joseph A. Calash

Publication number: 20140130622Abstract: A barrier assembly for a motor vehicle having a shift lever and a kit for assembling the barrier assembly are disclosed. The barrier assembly has a retainer, a lever plate, seals and spacers. The retainer has a retainer aperture extending from a first surface to a second surface. The lever plate is moveable and has a lever opening extending from a first face to a second face. A gliding surface allows the lever plate to move in a planar motion parallel to the retainer while supported on the retainer. A first seal is located on the first face of the lever plate proximal to the lever opening. A second seal is located on the first face of the lever plate distal to the lever opening. Spacers project from the retainer distal to the retainer aperture.Type: ApplicationFiled: July 14, 2011Publication date: May 15, 2014Applicant: International Truck Intellectual Property Company, LLCInventors: Nicholas Michael Cassaday, Craig Alan Newman, David M.
