Abstract:
The present invention relates to a sectional lifting door system. When the system is in normal operation, a door operator drives a cable drum to wind or unwind a cable for lifting or lowering slats. During a process of lowering the slats, if the slats is stopped or slowed unexpectedly (e.g. the slats hit an obstacle below), the door operator is disconnected from a shaft automatically. At this time, even if the door operator is still activated, the shaft does not rotate, the cable drum does not unwind the cable so that a certain tension force can be maintained on the cable and that the cable is prevented from loosening from the drum, thereby preventing the slats from falling off. Also, it can avoid the situation that the weight of the slats is completely applied to the obstacle because the cable drum continuously unwinds the cable.
Abstract:
An electromechanical strut and method of moving a closure member of a vehicle between an open position and a closed position is provided. The electromechanical strut includes a power drive unit including a motor, a leadscrew, a planetary gearset operably connecting the motor to the leadscrew, and an electromechanical brake assembly. The electromechanical strut further includes a telescoping unit including an extensible tube and a drive nut for converting rotary motion of the leadscrew into linear motion of the telescoping unit. The electromechanical brake assembly is selectively moveable between an engaged state, wherein the leadscrew is prevented from rotating to prevent relative axial movement between the power drive unit and the telescoping unit, and a disengaged state, wherein the leadscrew is permitted to rotate to allow relative axial movement between the power drive unit and the telescoping unit.
Abstract:
A motor drive device for moving a vehicle sliding door is provided. The device includes an electric motor, a force transmission mechanism operationally connectable to the vehicle sliding door and the electric motor to transmit a drive force provided by the motor to the sliding door, sensors at least for determining an instantaneous position of the vehicle sliding door, an electronic control unit for activating at least the motor, and a shift clutch coupled to the force transmission mechanism and couplable to the motor for load-independent coupling of the motor to the force transmission mechanism. The control unit, in the event of application of a sufficient force to the sliding door during a power-driven movement, either elevates a speed of the vehicle sliding door by elevating the transmitted drive force or decouples the force transmission mechanism and the motor with the shift clutch.
Abstract:
A door component has a controllable damping device and contains a magnetorheological fluid. Two connection units are movable relative to one another. One of the two connection units is connected to a support structure and the other one to a pivotable door unit. The device damps a movement of the door unit between a closed position and an open position in a controlled manner by way of a control unit. The magnetorheological damping device has a piston unit and a cylinder unit surrounding the piston unit. The piston unit divides a cylinder volume into two chambers. The piston unit is equipped with a first one-way valve. The two chambers are connected together, via an external return channel equipped with at least one controllable magnetorheological damping valve, to form a one-way circuit. When the piston unit moves in and out, the magnetorheological fluid flows through the piston unit in the same flow direction.

A vehicle includes: a frame, a rotatable door; an inhibitor comprising: an arm extending through a selective gate including: upper and lower springs respectively biasing upper and lower rollers against the arm; upper and lower stoppers configured to, upon activation, compress the upper and lower rollers against the arm, thus stopping rotation of the door; sensors, processor(s) configured to: activate and deactivate the stoppers based on sensed events.
Abstract:
[Problem] A drive unit (10) for driving, via a first and second geared cable (8, 9), a first and second member to be driven (sun roof and shade) provided to an opening part formed on the secured roof of a vehicle, wherein while being able to switch between a state in which the power from a motor (18) is transferred to both the first and second members to be driven and a state in which the power is selectively transferred to the first or second member to be driven, the member to be driven, in which the transfer of the power from the motor (18) is blocked, is prevented from moving during an impact when the vehicle collides in the selective transfer state. [Solution] The output path of the motor (18) is divided into a first and second output shaft (22, 42). Moreover, a first and second electromagnetic clutch (24, 44) for switching between connecting/disconnecting a first and second pinion gear (23, 43) to/from the first and second output shafts (22, 42) is provided, and each pinion gear (23, 43) is secured to a frame (3) so as to not be able to rotate when disconnecting from the clutches (24, 44).
Abstract:
A door brake system for braking and locking a hinged door of a motor vehicle includes a stop and a base body, which is moved relative to the stop via a swiveling motion of the door. The base body is hinged and/or detachably fastened to the door. The stop is arranged on the door frame or on a body of the motor vehicle. The base body is guided relative to the stop in a positive manner to improve an effect and/or the kinematics of the door brake system.
Abstract:
A hanger hinge for a folding door, window or similar closure having one or more panels, the hanger hinge comprising: A hanger bolt having a receiving portion in a lower end thereof adapted to receive at least a portion of an adjusting tool; A sleeve adapted to be supported on the lower end of the hanger bolt; At least one hinge leaf pivotally mounted on the hanger bolt and adapted to be fixed to a respective panel; and A locking mechanism comprising a locking member movable axially between a locked condition in which the locking member is engaged with the sleeve in a manner to substantially preclude rotation of the hanger bolt relative to the sleeve, and an unlocked condition in which the locking member is disengaged from the sleeve by axial insertion of the adjusting tool into the receiving portion, thereby freeing the hanger bolt for rotation relative to the sleeve.
Abstract:
An actuator system for use in selectively engaging an input to an output. The actuator system includes an input sub-system having an input component configured to connect to an input element which is in turn connected to a work source. The actuator system also includes an output sub-system being connectable to the input sub-system for receiving work from the work source via the input sub-system. The actuator system further includes an actuator sub-system having an active material and an actuating component. The actuator sub-system is configured so that the active material, when activated, causes the actuating component to move from a first state to a second state to disengage the input and output sub-systems.

A system, method, and computer storage configured for determining period-ending positions of multiple parts movable by select actuation of corresponding active materials. The operations include receiving, from a work-source sensor, work-source input indicating a distance moved by the work source and a direction of the movement, and determining, based on the work-source input and a first and second status histories, corresponding to a first and a second part, respectively, first and second distances travelled by the parts, respectively. Operations also include calculating, based on the first and second distances determined and first and second period-starting positions, corresponding to the first and second parts, respectively, first and second period-ending positions for the first and second parts, respectively.
