Patent number: 11479304Abstract: An energy absorber for interposition between a cover and a covered object includes a generally planar matrix of cells. Each of the cells includes a plurality of generally elongate micro-elements interconnected to form a cell micro-structure, with each cell having a respective energy absorption capacity such that an energy absorption capacity of the energy absorber varies across at least one direction. The cells are configured such that impulse of an object with the cover with the energy absorber sandwiched between the cover and the covered object causes a deceleration vs. time response in the object, beginning with a generally linear rise in the deceleration to a peak deceleration within 5 ms after the beginning of the impulse event, followed by a generally nonlinear decrease in the deceleration over a period of not greater than 15 ms to a final target deceleration of not greater than 10% of the peak deceleration.Type: GrantFiled: May 15, 2019Date of Patent: October 25, 2022Assignee: GM Global Technology Operations LLCInventors: Hanif Muhammad, Louis G. Hector, Jr., Mark A. Beauregard, Andrew C. Bobel, Michael J. Sigelko

Patent number: 9718434Abstract: An energy absorber according to various embodiments can include a structure having a predetermined cross-sectional profile. A hollow profile is formed within the structure. The pre-determined cross-sectional profile of the structure is configured based on a deceleration-time profile that includes a first period and a second period. The first period is defined by a substantially sharp and linear increase in magnitude of the deceleration of an impact until a maximum deceleration value is achieved. The second period is defined by a rapid decrease in the magnitude of the deceleration.Type: GrantFiled: January 21, 2015Date of Patent: August 1, 2017Assignee: GM Global Technology Operations LLCInventors: Louis G.

Patent number: 9616941Abstract: An approach to designing lightweight metal-polymer composite structures in a manner that decomposes the structure into at least two parts. In one specific embodiment, the approach is a manufacturing process for a vehicle that includes attaching an impact beam to a vehicle structure. The process includes providing a vehicle structure including a back plate of the impact beam being made of a suitable material, such as a metal, that can withstand high temperature processes. A front part of the impact beam including a front plate and a polymer core is attached to the back plate. The back plate is designed to provide structural integrity that allows the vehicle structure to go through the high temperature processes and/or the vehicle structure provides structural integrity that allows the back plate to go through the one or more processes. The back plate is also designed to provide desired functional characteristics of the beam.Type: GrantFiled: January 14, 2015Date of Patent: April 11, 2017Assignee: GM Global Technology Operations LLCInventors: Hanif Muhammad, Nilesh D.
