Patent number: 9522621Abstract: A tailgate assembly includes a structure, and a handle assembly attached to the structure. The handle assembly is moveable relative to the structure between a stowed position, an intermediate position, and a deployed position. The handle assembly includes a handle portion, and a mounting system attached to the structure and rotatably supporting the handle portion relative to the structure. The mounting system supports the handle portion for rotation about both a first axis and a second axis. The handle portion rotates about the first axis to move between the stowed position and the intermediate position to position the handle portion outside an interior space of the structure. The handle portion rotates about the second axis to move between the intermediate position and the deployed position, whereby a user may grasp the handle portion.Type: GrantFiled: April 23, 2015Date of Patent: December 20, 2016Assignee: GM Global Technology Operations LLCInventors: Gary W.

Patent number: 9522704Abstract: A tailgate assembly includes a drum that is rotatable about a drive axis, and an actuator for rotating the drum. A first cable is attached to the drum, and is spooled about the drum in response to rotation of the drum. The first cable extends through an opening in the tailgate structure, and is attached to a sidewall of a cargo box. A first guide assembly includes a first roller guide defining a first roller groove. The first cable is engaged with and guided by the first roller groove. The first guide assembly redirects a path of the first cable, and is rotatable relative to the tailgate assembly about a first guide axis. The first roller guide rotates about the first guide axis to maintain the first cable within the first roller groove as the tailgate assembly rotates about the tailgate axis between an open position and a closed position.Type: GrantFiled: July 28, 2015Date of Patent: December 20, 2016Assignee: GM Global Technology Operations LLCInventors: Gary W.

Patent number: 9463750Abstract: A tailgate assembly for a vehicle includes a structure that defines a compartment, and a cover that is moveably attached to the structure to cover the compartment. A compartment latch mechanism is attached to the structure for latching the cover to the structure. A compartment release mechanism is coupled to the compartment latch mechanism for actuating the compartment latch mechanism. The compartment release mechanism is disposed on one of a first lateral edge surface or a second lateral edge surface of the structure.

Patent number: 9073478Abstract: An energy absorbing headlamp assembly and a resettable headlamp assembly are disclosed. The assemblies include a first component and a headlamp assembly supported by the first component. The assemblies also include an energy absorbing device operatively coupled to the headlamp assembly and the first component to absorb energy when a first force is applied to the headlamp assembly. For the energy absorbing headlamp assembly, the device includes a link and a biasing mechanism coupled to each other such that the biasing mechanism continuously applies a second force to the link to bias the link to a first position when the headlamp assembly is in an initial position and a second position when the headlamp assembly is in a displaced position. For the resettable headlamp assembly, the device allows movement of the headlamp assembly from the displaced position back to the initial position when the first force is removed.Type: GrantFiled: March 29, 2013Date of Patent: July 7, 2015Assignee: GM Global Technology Operations LLCInventors: Gary W. Krajenke, Carl B. Corman, Anil A. Masih

Patent number: 9022452Abstract: A hinge assembly for a storage compartment includes a first component and a second component coupled to the first component. The second component is movable between a first position and a second position relative to the first component. A damper device includes a housing assembly supported by the first component and a finger attached to the second component such that the finger is movable with the second component between the first and second positions. The finger and the housing assembly are spaced from each other when the second component is in the first position, and the finger slidingly engages the housing assembly as the second component moves to the second position such that frictional engagement between the finger and the housing assembly dampens movement of the second component relative to the first component.Type: GrantFiled: May 13, 2013Date of Patent: May 5, 2015Assignee: GM Global Technology Operations LLCInventors: Gary W.

Patent number: 8997313Abstract: A counterbalance includes a first attachment strap, and an arbor rotatably supported by the first attachment strap. A second attachment strap is attached to the arbor, and is rotatable with the arbor about a winding axis. A spiral spring interconnects the first attachment strap and the second attachment strap. A spring support is attached to the second attachment strap. The spring support includes an annular wall that is disposed circumferentially about and concentric with the winding axis. The annular wall is radially positioned relative to the winding axis to contact an outermost coil of spiral spring, to position the spiral spring in a spiral orientation about the winding axis, such that each coil of the spiral spring moves away from the winding axis with a substantially constant angular velocity to provide a substantially equal radial spacing between adjacent coils of the spiral spring.Type: GrantFiled: June 30, 2014Date of Patent: April 7, 2015Assignee: GM Global Technology Operations LLCInventors: Gary W. Krajenke, Houng Yue Chang, Carol A. Feldmann

Patent number: 8978203Abstract: A hinge assembly includes a hinge box, and a decklid attachment bracket rotatably attached to the hinge box. The decklid attachment bracket includes a contoured surface. A compressible member is positioned for engagement with the contoured surface as the decklid attachment bracket moves between an open position and a closed position. The contoured surface defines an outer region, a recessed region, and an inner region. The outer region compresses the compressible member as the decklid attachment bracket moves between the open and closed positions to absorb energy and dampen movement of the decklid attachment bracket. The recessed region cradles the compressible member without substantially compressing the compressible member when the decklid attachment bracket is in the open position to secure the position of the decklid attachment bracket. The inner region compresses the compressible member to absorb energy, and limit movement of the decklid attachment bracket beyond the open position.Type: GrantFiled: March 29, 2013Date of Patent: March 17, 2015Assignee: GM Global Technology Operations LLCInventors: Gary W. Krajenke, Graham S. Foulkes
