The framework member includes an inflection portion that is inflected at a portion partway along a length direction. The reinforcing member is fabricated of fiber-reinforced resin and includes a pair of side walls formed in inflected flat plate shapes along the inflection portion. The reinforcing member is disposed in the closed cross section structure at the inflection portion of the framework member. The connecting plate connects the pair of side walls of the reinforcing member and connects a compression deformation side wall portion of the inflection portion with an extension deformation side wall portion of the inflection portion.Type: GrantFiled: June 18, 2014Date of Patent: September 27, 2016Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Hiroyuki Kurokawa

Patent number: 9452783Abstract: A structure that creates a compressive mechanical lock during an external force includes a beam, an offset bulkhead, and a compressive member. The beam has a hollow cross section, an axis, and a wall. The bulkhead is disposed within the hollow cross section and attached to the wall. The member has an axis and an end attached to one of the bulkhead and the beam wall. The member axis and the beam axis intersect with each other in a plan view to form an obtuse angle. The bulkhead is offset from the intersection in an offset direction, parallel to the beam axis and toward the opening of the obtuse angle. The external force causes the member end to deform the beam wall so as to create a pocket or compressive mechanical lock in the beam wall that mechanically locks the member end from moving in the offset direction.Type: GrantFiled: April 2, 2015Date of Patent: September 27, 2016Assignee: GM Global Technology Operations LLCInventors: Robert N. Saje, Michael E. Quigley, John C. Johnson
