A rear door assembly having a bracket, a rear door, a first movement mechanism and a second movement mechanism. The rear door has a lateral side with a slot formed therein. The first movement mechanism is attached to a rearward area of a vehicle body structure and is configured to move the bracket and the rear door from a closed orientation covering a rear opening in the vehicle body structure to at least an intermediate orientation partially uncovering the rear opening. The bracket has a pair of support pins extending in that extend into the slot with the support pins being supported on rollers within the slot. The second movement mechanism is disposed within the rear door to move the rear door relative to the support pins of the bracket along the slot.

A rear door assembly for a vehicle includes a motor having a shaft with a gear attached thereto. A first end of a lever is rigidly fixed to the shaft for rotation therewith proximate the gear. A belt is engaged with the gear. A rear door is pivotally attached to the vehicle and is movable between a door closed orientation and a door open orientation. The rear door has a gear assembly coupled to the lever. The rear door and the gear assembly are moved by the lever upon rotation of the lever by the motor. The gear assembly receives rotary motion from the belt such that an angular displacement of the rear door caused by the rotary motion of the belt during movement of the rear door between the closed orientation and the open orientation occurs at half the rate of the angular displacement of the lever.

An opening-and-closing body driving device includes an extendable unit including a spindle, a nut, a rod, a bearing, and a guide tube; and a driving unit. The guide tube includes an insertion portion, and an inner tube configured to allow movement of the nut in the axial direction and restrict rotation of the nut. A surface of the bearing facing a direction opposite to an insertion direction, in which the insertion portion is inserted, is defined as a first reference surface, and a surface of the housing facing a direction opposite to the insertion direction is defined as a second reference surface. A distance from the first reference surface of the bearing to a distal end of the inner peripheral wall is longer than a distance from the second reference surface of the housing to a distal end of the outer peripheral wall in the axial direction.

A rear door is movable between a door closed orientation covering a rear door opening and a gutter of a vehicle body structure, and a door open orientation exposing the rear door opening and the gutter. A four-bar linkage assembly supports the rear door for movement between the door open and the door closed orientations. The four-bar linkage includes a rearward member, a forward member and an extender. The rearward member has a first end pivotally attached to the gutter, a second end attached to the rear door and a protrusion spaced apart from the first and second ends. The forward member has a first end attached to the roof structure and a second end attached to the rear door. The extender has a lower end pivotally attached to the side wall and an upper end attached to the protrusion of the rearward member.

When it is determined that there is an individual abnormality, in which an individual drive section is in an abnormal state, while the opening/closing body is being moved by the drive sections or the opening/closing body is stopped in an open state, the opening/closing body operation device performs a restriction control on the drive section with the individual abnormality, the restriction control restricting the movement of the opening/closing body in the closing direction. The opening/closing body operation device makes a comparison of the driving state between the drive section subjected to restriction control and another drive section, and when it is determined that the drive sections are normal with respect to each other, the opening/closing body operation device deems the opening/closing body to be in a normal state and disengages the restriction control.

A rear vehicle assembly includes a body structure defining an opening having a first side edge and a second side edge and including a tailgate that is movable relative to the structure between at least one open position, in which the opening of the structure is accessible, and a closed position, in which the tailgate closes the opening of the structure, wherein the tailgate comprises at least a first side edge and a second side edge. The assembly includes an opening and closing device fixing the tailgate to the structure. The opening and closing device includes at least a first jack and a second jack, wherein the first and second jacks are each fixed between the structure and the first side edge.

A device and method for automatically closing a tailgate of a motor vehicle having a body and a tailgate closing device, is described. The tailgate closing device comprises first and second closing elements. A suspension strut is situated on a first side of the tailgate and a power strut is situated on a second side of the tailgate opposite the first side. The suspension strut and the power strut are both connected to the tailgate and to the body. The first closing element is situated on the tailgate and the second closing element is situated on the body. The first and second closing elements are designed to engage into each other during the closing of the tailgate to effectuate the closure of the tailgate. The torque acting via the power strut onto the tailgate is reduced during the closing of the tailgate when the distance between the first and second closing elements is less than a threshold value.

A vehicle door control system includes a door assembly, which includes a side door and a liftgate. The door assembly includes an actuation assembly that adjusts each of the side door and the liftgate between opened and closed positions. A sensor assembly defines a rear sensor field, a first side sensor field, and a second side sensor field. A controller determines whether a person in at least one of the rear sensor field, the first side sensor field, and the second side sensor field is a recognized passenger, determines a speed of the recognized passenger, determines whether the recognized passenger is carrying an object, and activates the actuation assembly to open at least one of the liftgate and the side door based on whether the recognized passenger is carrying an object, where timing of activation of the actuation assembly is based on the speed of the recognized passenger.

A door opening/closing device includes: a motor; and an output shaft arranged on a line extending from an axial center of the motor, power of the motor being transmitted to the output shaft via a deceleration mechanism, the door opening/closing device opening and closing a door via the output shaft by driving the motor. Positional deviation on both end surfaces of the output shaft is set to equal to or higher than 0.01 and equal to or lower than 0.1.

An electromechanical strut for moving a closure member between open and closed positions relative to a vehicle body includes a housing having an inner surface bounding a cavity extending along a central axis between opposite first and second ends. A power screw is disposed in the cavity in operable communication with a motor, with a gear assembly operably connecting the motor to the power screw. An extensible member has an outer cover tube received in the housing cavity and a drive mechanism for converting rotary motion of the power screw into linear motion of the extensible member. An annular gap extends between the inner surface of the housing and an outer surface of the outer cover tube. An annular bushing is disposed within the annular gap to minimize laterally play between the housing and the outer cover tube.
