Patent number: 11975634Abstract: A seat assembly includes a four-bar linkage for providing movement of the seat assembly between a plurality of positions in an automotive vehicle. The four-bar linkage includes front and rear links which simultaneously rotate to move the seat assembly between an easy entry position in which the seat assembly tilts forwardly and downwardly toward a floor of the automotive vehicle to allow ingress and egress behind the seat assembly, a stow position in which a seat cushion lowers toward the floor of the automotive vehicle and a seat back pivots toward and overlaps the seat cushion, and an intermediate design position in which the seat cushion is spaced from the floor of the automotive vehicle and the seat back is disposed generally upright to support an occupant. The seat assembly is capable of moving directly between the easy entry and stow positions without needing to intermediately return to the design position.Type: GrantFiled: December 19, 2019Date of Patent: May 7, 2024Assignee: Magna Seating Inc.Inventors: Ronald Zimmerman, II, Cheikh Dioum

Patent number: 11904739Abstract: A disc recliner mechanism for use in an automotive vehicle includes a plurality of pawls and a cam mounted between a guide plate and a tooth plate. Rotation of the cam moves the pawls between an extended position in which the pawls engage the tooth plate to lock the disc recliner mechanism and a retracted position in which the pawls disengage the tooth plate to unlock the disc recliner mechanism and allow rotation between the guide plate and the tooth plate. A notch is disposed on an engagement surface of a cam lobe disposed on the cam for reducing friction when the cam lobe engages a cam follower disposed on the pawls. The tooth plate includes a circumferential outer lip with a concentric channel for retaining lubricant and reducing rotational friction between the tooth plate and the guide plate.Type: GrantFiled: January 24, 2020Date of Patent: February 20, 2024Assignee: Magna Seating Inc.Inventors: Avery Folk, Kristof M Kurzeja, Kai Zhao, Louis Vetere, II, Detjon Marini, Cheikh Dioum, James Rudberg, Creston A Zang, Donald W Gray, Jr.

Patent number: 11679696Abstract: A seat assembly includes a swivel mechanism for providing rotation of the seat assembly in an automotive vehicle. The swivel mechanism includes a first plate assembly coupled to a second plate assembly at a rolling-element bearing to facilitate axial rotation of one of the first and second plate assemblies relative to the other of the first and second plate assemblies. A lock plate slidably disposed on the second plate assembly selectively engages a lock pin extending from the first plate assembly for movement between a locked position in which the swivel mechanism cannot rotate and an unlocked position in which the swivel mechanism can freely rotate. Actuation of the lock plate between the locked position and the unlocked position actuates movement of a wedge between a cinched position to stabilize the swivel mechanism and an uncinched position to allow unimpeded rotation of the swivel mechanism.Type: GrantFiled: November 7, 2019Date of Patent: June 20, 2023Assignee: Magna Seating IncInventors: Louis Vetere, II, Detjon Marini, Michael D Nacy, Kai Zhao, Cheikh Dioum, Omar D Tame

Patent number: 11597303Abstract: A long rail assembly for use in a vehicle includes a fixed rail, a movable rail, a power strip, a latch power connector, and a channel power connector. The fixed rail extends longitudinally along a floor of the vehicle. The movable rail is slidably coupled to the fixed rail. The power strip is coupled to the fixed rail. The latch power connector is removably coupled to the movable rail. The channel power connector is fixedly coupled to the movable rail and is in constant sliding contact with the power strip. When the latch power connector is coupled to the movable rail, the latch power connector frictionally engages the channel power connector thereby generating an electrical bridge between the power strip and the latch power connector to provide power to the long rail assembly.Type: GrantFiled: December 11, 2019Date of Patent: March 7, 2023Assignee: Magna Seating IncInventors: Kai Zhao, Michael D Nacy, Detjon Marini, Louis Vetere, II, Cheikh Dioum

Patent number: 11396252Abstract: An improved head restraint is provided for a reversible seat that is movable between two use positions, namely a forward-facing position and a rearward-facing position. The improved head restraint automatically pivots to a fold flat position upon unlocking of the seat, wherein the head restraint is positioned in this fold flat position during reversing seat movement, so as to reduce the seat height and clear the vehicle headliner. The head restraint is cable driven and operably connected to the seat linkages that control movement of the seat cushion and seat back during reversing movement. As such, the seat movement articulates the head restraint so that the head restraint angles forwardly toward the occupant in the forward-facing position and rearwardly toward the occupant in the rearward-facing position, while permitting the head restraint to automatically articulate to the fold flat position during travel of the seat between these two use positions.Type: GrantFiled: March 25, 2019Date of Patent: July 26, 2022Assignee: Magna Seating IncInventors: Michael D Nacy, Cheikh Dioum, Louis Vetere, II, Detjon Marini, Kai Zhao
