A powered actuator for moving a motor vehicle closure panel from a closed position to an open position and method of construction thereof. Powered actuator includes an electric motor configured to rotate a driven shaft and a gearbox coupled to the driven shaft. An extensible member extends through the gearbox to a proximal end on one side of the gearbox for attachment to one of a vehicle body or the closure member and to a distal end on an opposite side of the gearbox. Extensible member is configured to move between retracted and extended positions in response to rotation of the driven shaft. A contamination cover enshrouds the extensible member between the gearbox and the distal end of the extensible member. Contamination cover moves between an axially extended state and an axially retracted state while the extensible member moves between the respective retracted position and the extended position.

A drive device comprises a housing, a drive portion, a spindle member to rotate by driving of the drive portion, a nut member screwed with the spindle member); a moving member coupled to the nut member, and a rotation regulating portion which suppresses rotation of the nut member to move the nut member) in an axis X direction of the spindle member, wherein the moving member has a fragile portion to be broken by a predetermined force being weaker than a force required to break the nut member, and the fragile portion is configured that a fracture portion with which the nut member is pressable by the moving member toward the drive portion is formable when the fragile portion is broken.

A door opening and closing device includes a slider and a main link mechanism. The slider moves along a roof of the vehicle body in a front-rear direction, while supporting a proximal end portion of a back door in such a way as to be rotatable around an axis extending in a width direction. The main link mechanism includes one end and an opposite end rotatably coupled to the vehicle body and the back door, respectively. The main link mechanism adjusts a posture of the back door, depending on a door opening degree by changing a distance between a coupling point to the vehicle body and a coupling point to the back door. The main link mechanism decreases the distance as the door opening degree becomes larger.

A gate hinge apparatus and method adapted to be fastened to a vertical gate and to a post, comprising: a L-bolt having an elongated horizontal portion formed with thread and a transition into a vertical male member; a first bracket having a female mounting flange mounted to either the gate or the post disposed adjacent to the gate as elected by said user; a second bracket having a plate having one or more threaded means for holding and retaining said L-bolt, which is mounted to the gate or the post disposed adjacent to the gate; said L-bolt uses its vertical male member to connect to said female mounting flange; and said L-bolt has one or more nuts that are positioned on said thread on said elongated horizontal portion of said L-bolt to adjust said hinge. The method comprising: rotating the nut in a first angular direction to increase the gap width; and rotating the bolt in a second angular direction, to decrease the gap width.

A powered actuator for moving a motor vehicle closure panel from a closed position to an open position and method of construction thereof. Powered actuator includes an electric motor configured to rotate a driven shaft and a gearbox coupled to the driven shaft. An extensible member extends through the gearbox to a proximal end on one side of the gearbox for attachment to one of a vehicle body or the closure member and to a distal end on an opposite side of the gearbox. Extensible member is configured to move between retracted and extended positions in response to rotation of the driven shaft. A contamination cover enshrouds the extensible member between the gearbox and the distal end of the extensible member. Contamination cover moves between an axially extended state and an axially retracted state while the extensible member moves between the respective retracted position and the extended position.

A door component for pivoting a movable door of a motor vehicle has a drive with an electric drive motor in order to influence a pivoting of the door between a closed setting and an open setting. A position measure for an angular setting of the door leaf and a speed parameter for an angular speed of the door leaf are detected by a position sensor. During a pivoting of the door leaf with the speed parameter, an electrical setpoint current intensity for the electric drive motor is ascertained, and an associated setpoint voltage is set. Then the current intensity flowing through the drive motor is ascertained. The setpoint voltage is increased if the current intensity is lower than the electrical setpoint current intensity, and the setpoint voltage is decreased if the current intensity is higher than the electrical setpoint current intensity.

A spindle drive for a closure element of a motor vehicle. The spindle drive including a drive unit and a spindle-spindle nut transmission and including a spindle and a spindle unit for generating drive movements. The spindle drive including first and second drive sections, including first and second drive connections and configured to move relative to another between a retracted state and mi extended state over an adjustment path along a longitudinal axis of the drive unit. The spindle disposed in the second drive section and is axially fixed relative to the first drive connection, and the spindle nut is disposed in the first drive section and is axially fixed relative to the second drive connection. The spindle drive includes a support sleeve radially surrounding the spindle nut in the extended state and is mounted such that the spindle nut is axially moved relative to the two drive connections.

A control unit for establishing a functional connection between two gearing components comprises at least one control element, which can be moved in order to switch the control unit between different switching states, wherein the at least one control element is configured to provide a retaining force between the gearing components in a first switching state, and to allow movement of the gearing components in relation to one another in a second switching state. An actuator is used to move the at least one control element. A control mechanism controls the actuator. It is provided thereby that the control mechanism is configured to activate the actuator to switch the control unit from the first switching state to the second switching state, in order to move the at least one control element to reduce the retaining force (FH) based on a predetermined delay function (VF).

Provided is a vehicle door opening/closing device. Given that a door is in an initial fully-open position, a storage unit stores: a target speed map for defining a relation between the door position and the target speed of a motor; and information indicative of an arbitrary fully open position set by a user. A map speed computation unit calculates a map speed based on the target speed map, whereas a gradually decreasing speed calculation unit calculates a gradually decreasing target speed for decreasing at a prescribed deceleration rate as the arbitrary fully open position gets closer so that a prescribed terminal speed is reached at the arbitrary fully open position. A speed sequence control unit switches a set target speed to the gradually decreasing target speed from the map speed at a door position where the gradually decreasing target speed becomes slower than the map speed.

A power strut assembly for raising and lowering a panel of an automotive vehicle includes a strut housing defining two parallel axes, i.e. a motor rotary axis and a spindle rotary axis. A drive motor disposed in the strut housing has an output shaft rotatable by the drive motor about the motor rotary axis. A drive spindle with a threaded section at least partially disposed in the strut housing is rotatable about the spindle rotary axis to move a spindle nut on the threaded section of the drive spindle. A motor-spindle transmission for transmitting a rotation of the output shaft to the drive spindle includes a motor wheel secured to the output shaft and a spindle wheel rigidly coupled to the drive spindle. The motor wheel and the spindle wheel extend in a common plane of rotation.
