A winding mechanism for a sunscreen, for use in an open roof construction for a vehicle, includes a winding shaft which is supported at each longitudinal end to a stationary part of the open roof construction and forming a central axis for rotation. A winding tube for the sunscreen is rotatable around the central axis. At least one spring member is configured to bias the winding tube in a direction for winding the sunscreen thereon. The spring member is arranged adjacent to an inner surface of the winding tube and an outer surface of the winding shaft. At least one sleeve is configured to engage the spring member and inhibit noise from the spring member. The sleeve comprises an inner surface and an outer surface, wherein the at least one sleeve is connected along its inner surface to the winding shaft or along its outer surface to the winding tube.

An arrangement for a winding system has a shaft, which is designed such that it can rotate about a longitudinal axis, and a bearing bush, which is arranged in a recess of the shaft and is coupled to the shaft. The arrangement also may comprises a bearing element, which is arranged at a distance from the bearing bush in the recess of the shaft. A sliding element is arranged between the bearing bush and the bearing element in the recess of the shaft. Furthermore, a drive element is arranged such that it can rotate about the longitudinal axis in the recess of the shaft and is coupled to the bearing bush. The drive element is designed to wind and/or unwind a flexible element by means of the shaft.

An embodiment manually deployable vehicle door curtain assembly includes a curtain retractable into a vehicle door and deployable to cover a door window glass, a rod configured to be mounted on the vehicle door and to be simultaneously movable with the curtain to support the curtain, a slider slidably coupled with the rod and movable up and down together with the rod, and a support member configured to allow or prevent descending movement of the slider.

A security shade for use in an automotive vehicle. The security shade includes a cassette having a roll tube arranged therein. The roll tube has a shade panel fixed to the roll tube at one end thereof. The security shade also includes a bearing arranged in an end of the roll tube and a spring housing arranged in an end of the cassette. A motor spring is arranged within the spring housing and is axially fixed with relation to the roll tube and the cassette. The security shade also includes an end cap arranged over an end of a cassette. The security shade has the compressible end cap over each end of the roll tube and cassette.

A roll control device for a vehicle curtain has a damper, a speed-reduction device, and a unidirectional transmission device. The speed-reduction device is connected to the damper and has a sleeve, a gear mount, and multiple planet gears. The sleeve is hollow and has multiple inner teeth annularly arranged in the sleeve. The gear mount is mounted in and extends out of the sleeve and is connected to the damper. The planet gears are mounted rotatably on the gear mount and engage with the inner teeth in the sleeve. The unidirectional transmission assembly is connected to the speed-reduction device and has a transmission member and a unidirectional transmission device. The transmission member has a gear segment extending into the gear mount and engaging with the planet gears. The unidirectional transmission device is connected to the transmission member to control the transmission member to rotate in unidirectional.

A shade device for a vehicle includes: a shade; a retracting mechanism attached to a base end of the shade and retracting the shade in a stored state; a stay attached to a tip end of the shade; an extractable constant force spring; a rod, its tip end portion being attached to the stay and its base end portion being connected to the constant force spring, biased in a deploying direction of the shade by biasing force of the constant force spring, and transmitting the biasing force to the stay; a guide rail that stores the rod and an extracted portion of the constant force spring in the stored state of the shade, and guides the rod when the shade shifts from the stored state to the deploying state; and a locking mechanism that locks movement of the rod in the stored state of the shade.

The present invention discloses a winding device that includes a screen, a shaft portion to which one end of the screen is fastened, a rotary shaft member that fits to an end portion of the shaft portion so that the rotary shaft member is rotated around a rotation axis along an axial direction of the shaft portion, and a biasing portion that biases the rotary shaft member in a rotation direction for winding the screen. A relative rotation restriction structure and a movement restriction structure are formed on a fitting portion between the shaft portion and the rotary shaft member. The relative rotation restriction structure restricts a relative rotation of the shaft portion with respect to the rotary shaft member. The movement restriction structure restricts a movement of the shaft portion in the axial direction with respect to the rotary shaft member.

The shaft assembly according to an embodiment of the present disclosure includes: a shaft connected to a blind sheet; a pair of end caps each being coupled to one side and the other side of the shaft to perform the rotational movement together with the shaft; a gear unit connected to either one of the pair of end caps and has a plurality of gears to interlock with the rotational movement of the shaft; and an elastic unit connected to any one of the plurality of gears of the gear unit and providing an elastic force so that the gear unit provides a rotational driving force to the shaft between a deployed position and a retracted position of the blind sheet.
