A door drive assembly including: a drive arm including a first end configured to be rotatably coupled to the body and a second end configured to be rotatably coupled to the door. The door drive assembly also includes a drive mechanism coupled to the drive arm and configured to rotate the drive arm between an open position and a closed position. The door drive assembly also includes a control arm including a first end configured to be rotatably coupled to a vehicle body and a second end configured to be rotatably coupled to the door. The door drive assembly also includes a race configured to be disposed between the body and the first end of the control arm where the first end of control arm is configured to translate by a first distance along the race as the drive arm rotates between the open and closed positions.

A closure system includes a closure panel assembly and a hinge assembly configured to connect the closure panel assembly to a body. The hinge assembly includes a first hinge and a second hinge configured to be pivotably secured to the body and to the closure panel assembly in parallel, the hinge assembly establishing a four-bar linkage. The closure system includes a hinge cover configured to be fixed to the first hinge and pivotably connected to the closure panel assembly. The closure panel assembly is movable between a closed position and an open position via pivoting of the first hinge and the second hinge, the closure panel assembly at least partially covering the opening in the closed position and at least partially uncovering the opening in the open position. The hinge cover articulated alongside the first hinge and at least partially covers the first hinge in the closed position.

A back door structure includes a first arm, a second arm, a damper stay, and a supporting member. The first arm is fixed to an upper section of a vehicle body rear section, and is fixed to an upper section of a back door. The second arm is fixed to the upper section of the vehicle body rear section, and is fixed to the upper section of the back door. The damper stay is fixed to the back door, is fixed to the vehicle body rear section, and biases the back door in an opening direction. The supporting member is fixed to the second arm, is fixed to the back door, and biases the second arm substantially toward a vehicle upper side in a fully closed state of the back door.

A hinge assembly comprises a link arm; a first pivot connected to a door leaf and the link arm; a second pivot parallel, distant to the first pivot, and connected to a body leaf and the link arm; a first gear attached to the first pivot; a second gear attached to the second pivot; and an idler gear engaging the first and second gears at a plane substantially perpendicular to the first pivot.

A hinge apparatus can include a frame component of an aircraft interior component, a door component coupled to an aircraft door assembly, and a linkage assembly operable to rotatably move the door component between an open configuration, a partially open configuration, and a closed configuration. The linkage assembly can include a first hinge body coupled to the door component, a second hinge body coupled to the frame component, a main link pivotably coupled to the first hinge body and having a main link surface, and a first link pivotably coupled to the second hinge body and pivotably coupled to the main link. The first link may have a first link surface that is sized and shaped to mate with the main link surface when the door component is in the partially open configuration, the mating preventing movement of the door component from the partially open configuration to the open configuration or the closed configuration. Related methods are also provided.

A vehicle includes a body structure defining a front trunk having a front opening. A grille coves the front opening in a closed position and is pivotable about a vertical hinge, or a horizontal hinge along a top edge, secured to the body structure to provide access to the front opening. The grille may include a bin mounted on an inner surface of the grille and pivotable with the grille, a heating/cooling duct or a video display.

A spring assembly of a hinge assembly for a closure panel of a vehicle, the spring assembly comprising: a spring support bracket for connecting to a bracket of the hinge assembly; a spring mounted on the spring support bracket, the spring having an output end, the spring for biasing operation of the hinge assembly in order to move the closure panel towards an open position, the spring assembly including a holder mounted on the spring support bracket such that the holder is movable between an engaged position with the output end and a disengaged position with the output end; wherein when the output end is engaged with input end, the spring assembly is mountable to the hinge assembly.

A hinge assembly comprises a link arm; a first pivot connected to a door leaf and the link arm; a second pivot parallel; distant to the first pivot, and connected to a body leaf and the link arm; a first gear attached to the first pivot; a second gear attached to the second pivot; and an idler gear engaging the first and second gears at a plane substantially perpendicular to the first pivot.

A door hinge is attached by a base to a road vehicle. The door hinge carries a side door via a door mount, and it enables the door, when it is being opened, to be shifted upwards while at the same time shifting in an outward direction and rotating in a plane that is transverse to the outward direction. This decreases the risk of a lowermost parts of the side door hitting, e.g., a roadside curb near which the road vehicle is parked.

A vehicle includes a body structure defining a front trunk having a front opening. A grille coves the front opening in a closed position and is pivotable about a vertical hinge, or a horizontal hinge along a top edge, secured to the body structure to provide access to the front opening. The grille may include a bin mounted on an inner surface of the grille and pivotable with the grille, a heating/cooling duct or a video display.
