Publication number: 20230296122Abstract: A mounting structure apparatus for dynamically loaded structure joints is disclosed. The apparatus includes a first member having an aperture through a first surface and communicating with a counterbore in a second surface. A second member is included having a blind bore coaxial with the first member aperture. An insert is engageable with the counter bore, and a fastener is disclosed insertable into the first member aperture and interactive with the second member to join the first member to the second member.Type: ApplicationFiled: December 21, 2022Publication date: September 21, 2023Applicant: PRATT & MILLER ENGINEERING AND FABRICATION, LLCInventors: Kevin R.

Patent number: 11390198Abstract: A seat having a seat back pivotally connected to a seat pan, the seat back and the seat pan independently pivotal. At the pivot between the seat back and the seat pan there is a rotary energy attenuation device. The rotary energy attenuating device cooperates with a track system along the length of seat longitudinal members allowing for different directions of travel and height adjustment. The vehicle seat offers passive or active protection from impact and sudden acceleration due to accident or explosive events and is capable of automatically resetting.Type: GrantFiled: April 28, 2021Date of Patent: July 19, 2022Assignee: PRATT & MILLER ENGINEERING AND FABRICATION, LLCInventors: Celyn M. Evans, Kevin R. Kwiatkowski

Patent number: 10184553Abstract: In one embodiment, there is disclosed a blast mitigating differential housing for a vehicle, comprised of a first wall and a second wall in opposed spaced apart relation to each other. The first and second walls are separated by first and second side walls extending there between to define an inner space and an exterior surface. The side walls may be declined toward each other in a V shape. One of the first and second walls is equipped with an aperture to accommodate a vehicle drive line. The side walls are equipped with opposed apertures to accommodate the drive shafts and/or vehicle axles. The side walls may be further equipped with mounting structures along the exterior to accommodate a vehicle suspension system and/or steering elements. The inner space defined by the walls has a surface equipped for at least one vehicle differential mount.Type: GrantFiled: February 12, 2015Date of Patent: January 22, 2019Assignees: PRATT & MILLER ENGINEERING AND FABRICATION, INC., THE UNITED STATES OF AMERICA, AS REPRESENTED BY THE SECRETARY OF THE ARMYInventors: Kevin R.

Patent number: 10077974Abstract: In one embodiment, there is disclosed a modular, blast resistant suspension module for an armored vehicle. Each suspension module has a first and second axle assembly. The first axle assembly has a Short-Long Arm (SLA) suspension system pivotally connected to a blast resistant differential housing and the second axle assembly has a Road Arm (RA) suspension system pivotally connected to the differential housing. The suspension modules may be used to form 4×4 or 8×8 vehicle configurations.Type: GrantFiled: August 24, 2016Date of Patent: September 18, 2018Assignee: PRATT & MILLER ENGINEERING AND FABRICATION, INC.Inventors: Kevin R.

Patent number: 9908437Abstract: An improved seating system is provided for vehicles, including military vehicles. Center-facing seats are staggered to provide for a narrow vehicle profile, improved ingress and egress, and increased blast survivability. Seats may be reclined or reclinable, and seats may have seat pans upwardly movable away from a center aisle between rows of seats to increase an effective width of the aisle for improved ingress and egress.Type: GrantFiled: August 24, 2016Date of Patent: March 6, 2018Assignee: PRATT & MILLER ENGINEERING AND FABRICATION, INC.Inventors: Kevin R. Kwiatkowski, Kris Houghton, Celyn M. Evans

Publication number: 20180058820Abstract: An improved multiple layer hull system may be used in vehicle applications. An upper hull may be monolithic or may have a plurality of seams. A sacrificial lower hull may be entirely U-shaped or partially flat-bottomed, or may have a U-shaped or partially flat-bottomed base with outwardly extending wings complementing a lower surface of the upper hull. A blast deflector may be beneath the lower hull or base either as a separate part or as an integral part.Type: ApplicationFiled: August 24, 2016Publication date: March 1, 2018Applicant: Pratt & Miller Engineering and Fabrication, Inc.Inventors: Kevin R.
