A method for the operation of a motorized flap arrangement of a motor vehicle, wherein the flap arrangement has a flap which is pivotable with respect to a motor vehicle body, wherein the flap arrangement has a back-driveable drive arrangement for the motorized adjustment of the flap and a control arrangement for controlling the drive arrangement. It is proposed that an, in particular gravitationally induced, predetermined flap deflection is detected by means of the control arrangement from a de-energized intermediate position of the flap in a monitoring routine and, in response to the detection of the predetermined flap deflection, a holding routine is triggered in which the drive arrangement is adjusted to a flap-holding position in a holding control circuit.

An arm structure of an electronic device is provided. The arm structure includes an arm body, a first cam disposed on one side of the arm body and including a first hole into which at least a portion of a rotating shaft providing a folding operation of the electronic device is inserted, a peak and a valley being formed around the first hole, a second cam arranged side-by-side on a same axis as the one side of the arm body, spaced apart from the first cam, and including a second hole into which at least a portion of the rotating shaft is inserted, a peak and a valley being formed around the second hole, and a connecting part disposed on another side of the arm body and fastened with a rotating part providing rotation of the electronic device.

A door presenting device for a motor vehicle door element, having an electric drive unit and an actuating means, wherein the actuating means can be adjusted by means of the drive unit and a gear mechanism arranged between the actuating means and the drive unit, with the result that a movement of the door element can be enabled, and further having a locking means. The door element can be maintained in position by means of the locking means and the locking means can be electrically actuated, namely indirectly, preferably manually, actuated.

A vehicle door checker integrated with a power drive unit for an automobile door includes a direct current permanent magnet electric motor subject to cogging torque. The electric motor includes a central shaft. The vehicle door checker also includes a cogging torque increase device that is mounted to the central shaft externally of the motor. The cogging torque increase device includes pairs of oppositely magnetized permanent magnets that are mounted coaxially in a stator and rotor respectively about the motor shaft. The stator magnets and the rotor magnets shift into and out of alignment with each other as the shaft is rotated such that the motor is held in multiple discrete stable positions that correspond to check positions of an automobile door.

The present invention provides a drive unit and a method for attaching the same with which it is possible to improve the ease of attaching the drive unit to an attachment object. A limiting member is configured so as to limit the rotation of a drum when a lock member has fixed a pulley in a first position, and to allow rotation of the drum when a coil spring has caused the pulley to move to a second position. This makes it possible to prevent rotation of the drum in the state (vehicle mounting preparation state) before attaching the drive unit to a vehicle body. Therefore, it is possible to prevent a pair of cables from loosening inside a drum housing and catching on other constituent components. Accordingly, it is possible to improve the ease of attaching the drive unit to a vehicle body.

A heavy duty full energy, encoder driven non-handed electric door operator for industrial and commercial use a motor and an encoder configured to receive an external set of predetermined instructions. A motor mounting bracket connects the motor to a multi-layer housing. A controller is in electronic communications with the encoder and transmits external sets of predetermined instructions. Internally, the door operator contains a plurality of transfer shaft assemblies in communication with each other and connected with the motor at one end and an output shaft at the other end. The output shaft terminates at each end in a nondetachable spline. A detachable mounting plate serves as a base. The door operator operates heavy swing doors external to a building where the swing doors are required to be open or remain open in strong wind conditions.

A multi-link door hinge capable of facilitating the closing of a door and implementing the shock-absorbing performance of the door during the closing thereof. To this end, the multi-link door hinge includes: a main frame mounted to a main body of an object having a door; a door frame mounted to the door; a body frame rotatably connected to a first side of the main frame; an inner link and an outer link connecting the door frame to the body frame; a plate spring link allowing the outer link to be rotatably connected to the main frame; a locking piece rotatably mounted between side walls of the inner link; an elastic member; and a hook, a first side of which is fixed in the body frame and a second side of which is configured to be held in a second side of the locking piece.

An exemplary modular hold-open device is configured for use with a door closer comprising a body, a pinion rotatably mounted to the body, and an armature connected with the pinion. The modular hold-open device is configured to be mounted to the door closer, to selectively prevent rotation of the pinion by exerting on the pinion a resistive torque in a door-opening direction, and to cease exerting the resistive torque in response to a door-closing torque on the pinion exceeding a threshold torque to thereby permit rotation of the pinion in the door-closing direction.
