A rotary wing aircraft with a fuselage that is equipped with at least one rail, comprising at least one sliding element, in particular a sliding door or a sliding window, that is slidably supported by the at least one rail, wherein the at least one sliding element is at least slidable along the at least one rail by means of an opening sliding movement into an opening movement direction from a fully closed position into a fully opened position, wherein a dampening unit is provided that dampens the opening sliding movement of the at least one sliding element upon reaching of the fully opened position.

A hydraulically damped actuator suitable for closing a hingedly connected closure system includes a tubular cylinder barrel, an energy storing mechanism for storing energy when the closure system is being opened and for restoring the energy to close the closure system, and a hydraulic damping mechanism for damping a closing movement of the closure system. The damping mechanism has a closed cylinder cavity that is partly formed by a collar that is integrally formed with the tubular cylinder barrel, a guiding element that is bolted to said collar and a piston that is irrotatably and slideably with respect to the tubular cylinder barrel coupled to said guiding element. The guiding element is fixedly positioned with respect to the tubular cylinder barrel, without needing a screw connection.

A braking device for a movable door leaf comprises an electric motor operated as a generator, whose shaft is rotatable through a movement of the door leaf and at whose terminals a movement-dependent motor voltage is created and a brake circuit to which the motor voltage is applied or could be applied and which can be short-circuited via the motor terminals to dampen movement of the door leaf. In addition, the braking device comprises an emergency brake circuit to which the motor voltage is applied or applicable and via which the motor terminals can be short-circuited to dampen a movement of the door leaf. In doing so, means are provided which are designed to detect the presence of a malfunction of the brake circuit and to short-circuit the motor terminals via the emergency brake circuit when the presence of a malfunction of the brake circuit is detected.

In a method for the commissioning of a door or window closer which comprises an energy accumulator, a damping device with an electric motor being operable as a generator and a transmission element, the leaf is opened and/or closed at least once in a teach-in process, the angular position of the motor shaft is detected during opening and/or closing, a functional relationship is determined between the angular position of the motor shaft and an angular position of the rotatable leaf at least over an area of the opening width of the leaf and the functional connection is automatically taken as a basis for a subsequent actuation of the electric motor for the damping of the closing movement of the leaf.

An actuator producing an active movement between fastening elements of the actuator and damping a counter movement contains a main body having a first fastening element, an actuating body movable relative to the main body along an axial direction and having a second fastening element, and an electric motor for actively driving the actuating body exclusively in a driving direction along the axial direction and for passively damping a counter movement of the actuating body counter to the driving direction being brought about by external action on the fastening elements. An object assembly contains an object and the actuator in which the spring element is structurally separate from the rest of the actuator, and an interaction between the spring element and the rest of the actuator is achieved in an object to be operated by the actuator, at least in a correctly mounted state of the actuator.

The present approach relates to a door moving device (110). The door moving device (115) comprises at least a force providing device (200), a drive device (205), and a brake device (210). The force providing device (200) is configured to provide the force for controlling a movement of the door (110). The drive device (205) is configured to generate a drive torque for driving the force providing device (200). The brake device (210) can be actuated electrically, and is configured to generate a braking torque when not provided with electricity for braking the force providing device (200) for the door (110).

A movement damping device travels along a fixed track on roller wheels. Trolleys mounted on the roller wheels support the door along the track for movement of the door. Eddy-current interaction occurs between travelling magnets mounted on the device and fixed side plates of the track. The trolley moves horizontally as the roller wheels travel along horizontal support rails of the track. The track would be fixed to a supporting host structure and opposing side plates of the track support the respective rails. The trolley travels between the side plates when the door moves. The relative motion between the magnets and the side plates causes eddy-currents in the conducting side plates and consequent motion resistance

A lock for an access point such as a window includes a dual-action locking mechanism with a locking unit and a blocker. The locking unit is movable between a locking position and an unlocking position. The blocker blocks movement of the locking unit when the blocker is in a blocking position, and permits movement of the locking unit when the blocker is in an unblocking position. The lock may capture an insert attached to a tether to permit partial opening of a window while the unit is locked.

A door drive device for adjusting and/or locking a vehicle door relative to a vehicle body including an adjustment member, a drive element operatively coupled to the adjustment member such that the adjustment member is movable with respect to the drive element for moving the vehicle door, a sensor device for measuring a measuring quantity indicative of a movement of the vehicle door to provide a sensor signal, a brake device operatively connected to the drive element for braking a movement of the vehicle door, and a control device for controlling operation of the door drive device. The control device is configured to compute, from the sensor signal obtained from the sensor device, an acceleration value indicative of an acceleration of the vehicle door and evaluate the acceleration value to distinguish movement of the vehicle door caused by a gravity force from movement caused by a user action.

A system for adjusting a vehicle door relative to a vehicle body including an adjusting device, a control device for controlling the adjusting device. The control device is configured to receive an operating command and control the adjusting device based on receiving the operating command, and a sensor device for detecting an object. The control device is configured to evaluate for the purpose of collision protection monitoring whether an operating command is received in a near area relative to the vehicle door via an operating device. For collision protection monitoring, the control device is configured to use a first recognition area in a first operating mode upon receiving an operating command via an operating device in the near area, and in a second operating mode to use a second recognition area different from the first recognition area when an operating command is not received in the near area.
