Door operator systems are described herein that include the use of an adaptor. It should be understood that the adaptor may be utilized in order to operatively couple separate door operator assemblies together in a double door operator system. The adaptor may include control components (e.g., switches, buttons, toggles, levers, or the like) that are used to turn the door operator system on and off. While the adaptor may be used to operatively couple two separate door operator assemblies together to form a double door operator system, the adaptor may also be used within a single door operator system. Furthermore, with respect to double door operator systems, the system may also utilize a back plate assembly comprising two or more separate back plates (e.g., two or more back plate portions).

A leaf screen for an air intake of an HVAC system of a vehicle having a hood covering an engine compartment. The leaf screen includes a leaf screen body defining an air inlet opening covered by an integrally molded screen. A seal is integrally molded on a top surface of the leaf screen body in front of the air inlet opening. Bump-stops are integrally molded on the top surface that are engaged by an inner panel of the hood when closed. A method of making the leaf screen includes injecting a polymeric material into a mold to form a body portion. At least one elastomeric material is injected into the mold on one side of the body portion to form a seal and a plurality of bump-stops.

The invention relates to an automatic door system including a first door leaf of a first door leaf arrangement that can be displaced in the longitudinal direction. A floor-side guide rail arrangement extends in the longitudinal direction and includes a first floor rail arrangement. The at least one first door leaf includes an engagement element which is arranged on an underside of the at least one first door leaf. The at least one first floor rail arrangement includes at least one first floor rail and at least one connection and/or functional element, wherein the at least one connection and/or functional element is arranged on an end side of the at least one first floor rail. The at least one first floor rail includes at least one first guide groove extending in the longitudinal direction. The at least one engagement element of the at least one first door leaf of the at least one first door leaf arrangement is inserted into the at least one first guide groove and is guided in the longitudinal direction by the at least one first guide groove.

A spindle drive assembly for opening and/or closing a vehicle flap is described, having a spindle and a spindle drive motor coupled thereto by means of a two-stage epicyclic gearing. A ratio of a number of teeth of each planet gear of a first epicyclic gearing stage to a number of teeth of each planet gear of a second epicyclic gearing stage is selected such that, in operation, a first sound frequency that is emitted by the first epicyclic gearing stage differs by an integer multiple of a semitone from a second sound frequency that is emitted by the second epicyclic gearing stage. In addition, a vehicle flap with such a spindle drive assembly is presented.

The invention relates to an electric servo drive (10) for a motor vehicle, comprising an actuator (13) for at least indirectly moving an element (14) of the electric servo drive (10). According to the invention, the electric servo drive (10) additionally comprises at least one sensor element (15) which is designed to sense a measured variable that is not used for moving or actuating the element (14) of the actuator (13).

A movement control device is provided comprising a housing (11) with an elongate push rod (10) mounted therein for reciprocal movement along a longitudinal axis (x). One end of the push rod extends out of the housing. A spring (12) is arranged between the housing and the push rod to provide a biasing force on the push rod in a first direction parallel to the longitudinal axis. A damping device (15) is arranged between the housing and the push rod to provide a damped resistive force in a direction opposite to said first direction. An indexing mechanism (18) controls movement of the push rod relative to the housing. The damping device is arranged to act along an axis (y) that is parallel to the longitudinal axis of the push rod and spaced apart from it.

The present disclosure illustrates a sectional door driving device including a power assembly, a chassis assembly and a driving assembly. The power assembly includes a motor, a gear set and a control unit, and the power assembly is fastened on a main chassis of the chassis assembly. The driving assembly includes two half-gears respectively in semicircular cylinder shape, and each of the two half-gears has a combination surface which is formed with an engagement assembly, and the two half-gears are engaged by the engagement assemblies thereof to form a circular gear to cover a shaft of a sectional door mechanism. The gear set includes an output gear configured to drive the circular gear and the shaft to rotate. The sectional door driving device can be separated from the shaft easily for repair, and the sectional door driving device can also be installed on the existing sectional door easily.

The disclosure makes an insulating component and a sensor bracket to be an integrally molded article, simplifies the manufacturing process and cuts down the cost. A sensor holder and a sensor bracket made of a resin are made to be an integrally molded article, wherein the sensor holder inside which a pair of electrodes are arranged, and the sensor bracket made of a resin which holds the sensor holder and is attached to a tailgate. During an operation of filling a molten resin to a cavity, a part of the sensor holder is melted by the molten resin, and thus integrating the sensor holder and the molten resin, therefore, the two components can be structurally and firmly integrated. Accordingly, a touch sensor unit which endures long-term use can be obtained.

A sliding and braking device (10) of sliding doors closing off and opening two adjacent rooms comprises a profile (12) made of metal or other suitable material having a substantially C shaped cross-section with a lower horizontal branch or base (22), attached with screws or equivalent means to the inner face of the door (14) to be moved and fitted with an inverted U seat constituting the sliding guide (19) for one or more wheels (20) of at least one support (40) attached to a wall (42), above the through opening between said rooms. The device further comprises two damper stops (24), each consisting of a piston (26), a coil spring (28) overlapping one another and a pivoting slider (38). The two damper stops (24) are opposite and fixed along the base (22) of the profile (12) misaligned with each other; the pivoting slider (38) which such stops are fitted with, are provided with and abutted by an appendage (56) and (58) projecting from the support (40) and defining an actuator.

A damping assembly for a flap fitting includes first and second spring holders, between which at least two coil springs are arranged. In each of the at least two coils springs, a linear damper having a damper housing and having a piston rod slidable relative to the damper housing is arranged between the first and second spring holders.
