A curved winding tube assembly for a roller blind system includes a static inner tube and a segmented outer wherein a first segment of the segmented outer tube provides bearing support to a floating end of the static inner tube and wherein a securing member engages a plurality of interconnected. A roller blind assembly includes such a curved winding tube.

A drive circuit for a roof assembly, the roof assembly comprising a roof panel movable between a closed position and an opened position by a motor, the drive circuit comprising an H-bridge comprising switch elements for controlling the speed of the motor; a reverse polarity protection switch, such as a MOSFET; and at least one measurement circuit. The drive circuit is configured for receiving a PWM-signal with a duty cycle for operating the H-bridge. The at least one measurement circuit is configured for performing a current measurement of at least one of the switch elements of the H-bridge and/or the reverse polarity protection switch, respectively.

A roof system for a vehicle having an opening in a stationary roof comprises a panel movable in a between a closed position and an, at least partially, open position by an operating mechanism. The operating mechanism comprises: a pair of guide rails at opposite sides of the opening; a driven slide with at least one operating channel which moves along one of the guide rails and a lever with a first end connected to the panel. A cam engages and is driven by the operating channel so that the panel moves between its closed and open positions. The driven slide and the lever have at least one pair of cooperating engagement members positioned such that during a normal operation of the roof system, said engagement members are out of engagement, and upon deformation of the driven slide and/or the front lever said engagement members are in engagement.

A roof system for a vehicle having an opening in a fixed roof of the vehicle includes a panel which is movable relative to the fixed roof between a closed position, a tilted position in which a rear end of the panel is lifted and a fully opened position, and a rear lever for lifting a rear end of the panel. The panel at its rear end is provided with a bracket comprising a guide curve in which the rear lever movably engages, such that the rear lever is movable between a position engaging a first guide curve section in which the panel assumes a first tilted position in which its rear end is lifted to a first height, and a position engaging a second guide curve section in which the panel assumes a second tilted position in which its rear end is lifted to an increased second height.

A transparent roof panel assembly for a vehicle, and a vehicle comprising said transparent roof panel assembly, comprises a panel, a light source and a light in-coupling element wherein the light source is provided in a serviceable manner. A method for attaching and removing said light source is also disclosed.

A roof assembly for a vehicle includes a pair of guide rails a roof panel movably supported on the guide rails and configured to close the roof opening. Each guide rail slidably supports a respective operating mechanism for the roof panel, each operating mechanism comprising a front mechanism, a tilting mechanism, a locking mechanism, and a driving slide. The operating mechanism further comprises a panel bracket which is pivotally connected to the front lever and slidably connected to the sliding claw. The driving slide is configured for operating the front mechanism on a first side of the panel bracket in the guide rail and for operating the locking mechanism on a second, opposite side of the panel bracket in the guide rail. The tilting mechanism is operable by the locking mechanism on the second side of the panel bracket in the guide rail.

A display device for attachment to a vehicle roof, comprises a display screen and an operating mechanism to move the screen into a storage position and an operational position. The operating mechanism includes at least one guide rail mounted to the roof and a first and second slide shoe slidably guided in the guide rail. A screen support supports the screen and is pivotally connected to the first or second slide shoe. A lever is pivotally connected to the screen support and to the other of the first and second slide shoes to at least rotate the screen between its operational and storage positions by changing the distance between the first and second slide shoes. Only the first slide shoe is driven by a drive motor. The second slide shoe has a locking mechanism to lock the second slide shoe where the screen is moved toward its operational position.

A roof system for a vehicle includes a sunshade assembly, which comprises a flexible sunscreen having opposed longitudinal and transversal edges and a winding shaft carrying a winding roller configured for winding and unwinding the sunscreen. The roller is provided with an internal spring connected between the roller and the shaft and is preloaded to wind the sunscreen thereon. Two drive cables extend along and are capable of a movement parallel to the longitudinal edges of the sunscreen. The cables are connected to opposite ends of an operating beam for moving it to wind and unwind the sunscreen. A rotatable gearwheel is positioned at only one end of and concentrically fixed to the shaft and is drivably in engagement with one of the drive parts, such that a displacement of said one of the drive parts results in a rotation of the shaft in the same direction as the roller.

A display device attachable to a vehicle roof construction, comprises: at least one foldable display having first and a second display parts, a first drive system mounted to the roof construction for moving the display into a substantially horizontal orientated stored folded position, and into an operational unfolded position. In their operational position, the first display part is above the second display part, seen in a vertical direction and such that a flexible display part connects the first and second display parts. The display part can show a part of an image and connects the first and second display parts such that a visually uninterrupted image across the whole image producing side of the display may be observed by the occupants. The first drive system comprises an electric motor, a gear device driven by the electric motor and being capable of rotatably driving the first and second display part.

A roof system for a vehicle, comprises a movable roof panel for a roof opening. Stationary guide rails slidably guide an operating mechanism that operates the panel. The operating mechanism comprises a first device for moving the panel rear edge towards a raised position and a second device including a lever for moving the panel front edge in a vertical direction. A guiding slide is driven to move the panel both vertically and horizontally through the first and second devices. The lever comprises a first pivotal connection to the panel, and, remote from that spaced second and third connections. The third connection connects the lever to the guiding slide. A fourth connection on the lever is arranged near the third connection and connects the lever to the guiding slide when the third connection is disconnected from the guiding slide during a movement of the front edge of the panel upwardly.
