A power swing door actuator for moving a passenger swing door relative to a body portion of a motor vehicle. The power swing door actuator includes a housing rigidly fixed to the swing door, a motor mounted to the housing, a connector link having a first end pivotably coupled to the vehicle body portion and a second end pivotably coupled to a drive nut of a spindle drive mechanism. A leadscrew of the spindle drive mechanism is rotatably driven by the motor for causing relative translational movement between the drive nut and the leadscrew which, in turn, results in pivoting movement of the connector link while the vehicle door swings between open and closed positions in response to selective actuation of the motor. The power swing door actuator is further equipped with an integrated door check mechanism.

A powered vehicle closure system includes a controller that is configured to control a force of a powered actuator to provide smooth opening and/or closing operations.

A door component has a controllable damping device containing a magnetorheological fluid as a working fluid. Two connection units can move relative to one another. One of the two connection units can be connected to a support structure and the other of the two connection units can be connected to a moveable door unit of a vehicle in order to damp a movement of the door unit between a closed position and an open position under control of a control device. The damping device has an electrically adjustable magnetorheological damping valve which is current-less in an adjusted state of the damping valve. A damping property of the damping device is continuously adjusted as needed via an electrical adjustment of the damping valve.

A door device for a vehicle includes a latch drive device configured to unlatch a swing door by driving a latch mechanism, a door hold-open device configured to hold the swing door at an opened angle by applying a braking force to the swing door, a door open switch issuing an operation request of the latch drive device to open the swing door; a door stop switch issuing an operation request of the door hold-open device, and a grip portion including the door open switch and the door stop switch to issue the operation requests of the door open switch and the door stop switch in a state where an occupant of the vehicle holds the grip portion.

A vehicle door presenting system includes an actuator striker positioned at one of a vehicle body surface or a vehicle door, and an actuator positioned at the other of the vehicle body surface or the vehicle door and engagable with the actuator striker. The actuator is configured to move the vehicle door between a fully closed position and a partially open position via interaction between the actuator and the actuator striker. The actuator includes a retaining portion to maintain engagement with the actuator striker. The retaining portion retains the vehicle door in the partially open position to prevent the vehicle door from moving toward a fully open position.

A vehicle door arranged on a vehicle body and a device for manually and/or electromotively adjusting the vehicle door relative to the vehicle body including an output element moved on adjustment of the vehicle door and a switching device configured to switch between a coupling state and a freewheeling state, and a control device. The switching device configured to couple the output element to a further assembly in the coupling state and to disengage it from the further assembly in the freewheeling state such that the output element is movable with respect to the further assembly. At least one sensor device configured to detect a signal indicating an occupant's wish to get out of the vehicle, and configured to evaluate the signal for detecting an exit wish and actuate the switching device to switch into the coupling state.

A motor vehicle door includes an arrester device having a magneto-rheological fluid for holding the motor vehicle door in position, and a coil for solidifying the magneto-rheological fluid that is disposed adjacent to a liquid-tight interior space, with the interior space containing one or more components which can be moved relative to other components in the interior space. A relative movement between these components is slowed down by solidifying the magneto-rheological fluid and the slowing down of the relative movement causes the motor vehicle door to be held in position. The coil is part of a switchable hard magnet which is selected such that a sedimentation-stable, magneto-rheological fluid is obtained. The motor vehicle door may thus be reliably held in a freely selectable position.

A method for damping a movement of a door system of a vehicle that is equipped with a damping system having an adjustable and controllable damping action. A movement of the door system between a closed position and an open position is damped in a controlled manner. A measurement of the change in speed of the speed of movement of the door system is calculated and if the change in speed exceeds a predefined limit value, a set, gentle damping action is changed over to a greater damping action.

The present invention is a positioning mechanism device to prevent the motion of one surface with respect to a second surface, in one direction. The positioning mechanism uses a linear adjusting lock, an actuator, and an over-ride mechanism. The linear adjusting lock uses a coil spring to hold a rod in place. When firmly coiled, the coil spring is able to grip a smooth rod and prevent axial motion. When the coil spring is uncoiled, slightly, it releases its grip on the smooth rod, allowing axial motion. The positioner mechanism uses an actuator and release blade to release the coil spring. Additionally, the over-ride mechanism can be used to release the release blade in one direction without use of the actuator. When the coil spring is released by either the actuator or over-ride mechanism the two surfaces can be re-positioned relative to one another.
