A manufacturing method of a roller shade device including a fixed shaft, a winding cylinder which has flexibility, and within which the fixed shaft is inserted to be positioned so as to be rotatable therewith, a shade sheet, and a torsion spring applying a rotary force to the winding cylinder includes a process of inhibiting an axial end portion of the winding cylinder from rotating relative to the fixed shaft in a state where the torsion spring applies the rotary force to the winding cylinder, the axial end portion being away in an axial direction from a position where the torsion spring is connected to the winding cylinder, and a process of bonding the shade sheet to the winding cylinder in a state where the axial end portion is inhibited from rotating.

A shading blind for a roof window of a motor vehicle is disclosed, having two guide rails, a roller blind element which has two lateral, flexible guide structures with which it is guided in the guide rails, and a receiving space for the roller blind element, the roller blind element being adjustable between an extended position in which it is largely located outside the receiving space, and a retracted position in which it is largely located in the receiving space, wherein the receiving space, measured in the adjustment direction of the roller blind element, has a length which is approximately half of the adjustment path between the extended and the retracted positions, the height of the receiving space, measured perpendicularly to the plane of the roller blind element located between the guide rails, is such that when the roller blind element is deflected in the receiving space by approximately 180, the guide structures are only elastically deformed and a rear edge of the roller blind element is permanently attached in the receiving space.

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.

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.

A roll shade device includes: a fixed shaft fixed to a roof of a vehicle and extending in a vehicle width direction; a flexible rotation shaft into which the fixed shaft is inserted; a light shielding sheet whose first terminal end portion is fixed to the rotation shaft, and which is in an unfolded state where light passing through a light transmitting portion provided to the roof is blocked or is in a winding state where light is allowed to pass; and a torsion spring which is accommodated between the fixed shaft and the rotation shaft, and which biases the rotation shaft in a rotation direction in which the light shielding sheet is wound so that twist of the rotation shaft becomes symmetrical in the vehicle width direction.

The dashboard-mounted retractable sunscreen is a sunscreen that may be deployed from a housing mounted in the area of a vehicle dashboard. To deploy the sunscreen, a shade is pulled from within the housing by grasping a hook on the top of the shade and pulling up. The same hook is used to hold the shade in place by passing the hook over the vehicle's rearview mirror. When no longer needed, the shade may be easily retracted back into the housing by separating the hook from the rearview mirror and lowering the hook towards the housing. Springs in each side of the housing enable the shade to wrap itself around a central rod within the housing. Width adjustment knobs on each end of the housing help hold the housing in place by pressing against the vehicle's left and right A pillars.

A roof roller blind system for a motor vehicle, having a spring cartridge and a winding shaft is described, wherein the winding shaft comprises a non-circular inner cross-section, wherein an end portion of the spring cartridge contacts the inner cross-section of the winding shaft at least in portions in a torque-transmitting manner. A method for mounting a roof roller blind system for a motor vehicle is also described.

A torsion assembly has a connection member and a torsion spring. The connection member has a connection segment and a holding protrusion. The connection segment has a connection hole. The holding protrusion is formed in the connection hole. The torsion spring has a spring body and a connection leg. The connection leg is connected with the connection segment of the connection member, and has a rod segment, a bent segment, and a hook segment. The connection leg is kept from escaping out of the connection hole by the holding protrusion.

A shading structure for a motor vehicle windshield including a profiled pull-out section attached to the shading structure at an end face and which is moved between a lowered rest position and an extended functional position in lateral guiding rails fixed to the vehicle by a drive transmission means. In the rest position, the shading structure is lowered into a shaft fixed to the vehicle through a passage. The passage is closed by a lid which is pivoted between open and a closed positions, and a control mechanism is provided for opening and closing the lid. The control mechanism is coupled to a displacement movement of the pull-out section. The control mechanism has a traction mechanism that controls the lid between the open position and an intermediate position located between the open position and the closed position of the lid, on the basis of the pull-out section passing through the passage.
