Publication number: 20210283999Abstract: A liftgate structure having a composite inner panel with an outside surface having a lower perimeter surface area extending across the entire width of the composite liftgate structure. Connectable to the inner panel is a composite outer panel that has an inside surface with a lower perimeter surface area extending across substantially the entire width of the liftgate structure. Between the inner panel in the outer panel is a backing curtain. The backing curtain is connected to the outside surface of the inner panel such that the backing curtain is positioned between the outer panel on the inner panel and extends substantially across both the lower perimeter surface area of the inner panel and the lower perimeter surface area of the outer panel. The backing curtain prevents broken pieces of the outer panel for moving past the backing curtain in the event of an impact on the liftgate structure.Type: ApplicationFiled: October 6, 2017Publication date: September 16, 2021Applicant: Magna Exteriors Inc.Inventors: William J.J. Harney, Keijo J. Huotari, Mark P. Birka, Heiner Salzmann, Gerard Oslzewski, Steven Grgac

Publication number: 20210174793Abstract: An independent add-on automated vehicle lift gate system utilizing existing key fob authentication circuits in combination with an independent voice control system. The system uses microphones in connection with audio acquisition hardware and voice recognition hardware that actively listen for one or more voiced commands from a user outside of a vehicle. Before activating the mechanical system, which is for example the actuator of the lift gate and lock mechanism for the lift gate, the system will wait for confirmation from a separate vehicle system that monitors and notifies the vehicle lift gate system when an identification code is received from a key fob transponder located in a predetermined proximity of the vehicle, thereby authenticating the one or more voiced commands detected by the microphones.Type: ApplicationFiled: May 24, 2018Publication date: June 10, 2021Applicant: Magna Exteriors Inc.Inventors: Steven GRGAC, Yassir RIZWAN, Thomas REIDEMEISTER, Guy Martin TCHAMGOUE

Publication number: 20190329466Abstract: Reinforced composite structural members and methods of forming thereof. The method includes providing one or more reinforcements, one or more adhesives, a mold with a mold cavity and resin. The one or more reinforcements are coated with the one or more adhesives and then are placed within the mold cavity. Next the mold cavity is closed and a step of overmolding the one or more reinforcements by injecting molten resin into the mold cavity, then curing the molten resin to form the structural member. The one or more adhesives coated onto the one or more reinforcements facilitates the bonding of the resin of material to the one or more reinforcements.Type: ApplicationFiled: December 8, 2017Publication date: October 31, 2019Applicant: Magna Exteriors Inc.Inventors: Steven Grgac, Gari Schalte, Philip Grella

Patent number: 9950471Abstract: A method for forming butt joints between thermoplastic members by resistive implant welding. A tongue is formed on one member to be joined and a complementary groove is formed in the other member. A resistive implant is placed between the tongue and the groove which are then pressed together by an applied pressure. An electric current is run through the resistive implant to melt a portion of the thermoplastic material of both the tongue and groove, and the melted plastic intermingles through the implant. When the electric current is removed, the plastic cools, forming a weld.Type: GrantFiled: October 5, 2015Date of Patent: April 24, 2018Assignee: Magna International Inc.Inventors: Steven Grgac, Bradford D.

Patent number: 8887646Abstract: A pallet used for stowing and transporting items for shipping. The pallet design of the present invention includes a top deck, a bottom skid, and several posts for providing support between the top deck and bottom skid. The posts are integrated with either the top deck or bottom skid. Within each pallet post is a steel tube reinforcement that is overmolded directly into the bottom skid, or is assembled after the pallet post is molded. The supports, which are typically hollow posts, are molded onto either the top deck or bottom skid, and a thermoplastic weld or adhesive joint is applied to the posts to complete the assembly. The palled having the integrated posts and reinforcements provides an economical approach of reinforcing pallet posts to absorb tow fork impact.Type: GrantFiled: April 7, 2011Date of Patent: November 18, 2014Assignee: Magna International Inc.Inventors: Tommy J.

Patent number: 8399084Abstract: A novel method and set of structures for performing resistive implant welding of two plastic components to form an assembly. A first one of the components to be welded includes a channel structure which receives the resistive implant and maintains it in a desired position until the welding operation is performed. The second component to be welded includes a complementary structure including a land which is sized to engage the channel structure and captive resistive implant on the first component. The two components are pre-weld positioned with the land in the channel structure and the positioned components are then placed in a press which exerts a pre-selected pressure on the interface between the channel and the land. Next, a pre-selected electric current is passed through the resistive implant to heat it and to bring the plastic material of the channel structure and the land to their molten points, where they intermingle through the resistive implant.Type: GrantFiled: December 8, 2008Date of Patent: March 19, 2013Assignee: Magna International Inc.Inventors: Steven Grgac, Bradford D.

Patent number: 8361583Abstract: A welded joint for structural component having two or more portions fused together at a weld line. An adhesive layer is placed between the two or more portions at the location of the weld line and a conductor is placed between the two or more portions in operable contact with the adhesive. Energy is transmitted through the conductor and into the adhesive layer to activate the adhesive layer and create the weld line that defines the welded joints between the two or more portions. The welded joint of the structural component allows energy to be injected into the adhesive layer via the conductor in order to cause the adhesive layer to activate from the inside of the adhesive outward. The conductor can be placed adjacent the adhesive layer or within the adhesive layer in order to cause the adhesive to be activated from the inside outward.Type: GrantFiled: February 26, 2010Date of Patent: January 29, 2013Assignee: Magna International Inc.Inventors: David Scott Dyke, Jeremy Alan Panasiewicz, Steven Grgac

Patent number: 8323444Abstract: An implant applicator and method for positioning a resistive implant material on a first plastic component to be used to form a resistive implant weld between that first plastic component and a second plastic component. The resistive implant material is heated and pressed into a targeted surface of the first plastic component to tack the resistive implant into place. The second plastic component is positioned over the tacked resistive implant and a weld formed in a known manner. The resistive implant material can be heated for tacking by passing an electric current through it before it is pressed into the first plastic component by a second member or by contacting the resistive implant material against a separately heated surface prior to pressing it into the first plastic component.Type: GrantFiled: December 11, 2008Date of Patent: December 4, 2012Assignee: Magna International Inc.Inventors: Steven Grgac, Bradford D.
