Patent number: 11885170Abstract: A protection device for a window opening of a motor vehicle, with a window pane shiftable between a closed position closing the window opening and an open position opening the window opening, at least one shading structure shiftable between a window shading position and a window unblocking position, and a cable drive system for driven shifting of the window pane and/or of the shading structure and having a drive and a cable strand movable by the drive. A mechanical coupling arrangement which, depending on the position of the window pane, the shading structure and movement of the cable strand, is transferable between a first coupling state, in which the shading structure is coupled to the cable strand for the driven shifting and the window pane is decoupled therefrom, and a second coupling state, in which the shading structure is decoupled from the cable strand and the window pane is coupled to the cable strand for the driven shifting.Type: GrantFiled: April 28, 2022Date of Patent: January 30, 2024Assignee: BOS GMBH & CO.

Publication number: 20240025341Abstract: Vehicle-bodywork part including a bodywork aperture and a wing-mirror arrangement with a carriage unit, or a wing-mirror arrangement for a vehicle-bodywork part including such a carriage unit. The carriage unit carries an optical detection device and is displaceable between a rest position, in which the carriage unit is recessed in a flush state in the bodywork aperture, and an operating position, in which the carriage unit extends out of the bodywork aperture. A drive system is coupled to the carriage unit to displace same between the rest and the operating positions. The drive system has a cable-pull arrangement deflected around at least one deflecting roller. An elastically compliant securing device is provided, the securing device being tensioned between opposite cable strands of the cable-pull arrangement in the region of the deflecting roller, in order to avoid disengagement of a cable strand from the deflecting roller.Type: ApplicationFiled: July 18, 2023Publication date: January 25, 2024Inventor: Jan LEKAR

Patent number: 10682900Abstract: Shading device for a vehicle interior including a flexible shading structure displaceable between a compactly stored rest position and a deployed shading position and which is provided with a pull-out profile on an end region. The pull-out profile has a central portion and on opposite end sides of the central portion has telescopic shiftable guiding portions which are displaceable in vehicle-related guidances. A shield is disposed on the central portion and is mounted to be movable relative to the central portion between a rest condition and a functional condition, and a forced control device is provided for displacement of the shield in at least one direction between the rest condition and the functional condition to displace the shield in response to a shifting movement of at least one guiding portion.Type: GrantFiled: February 22, 2017Date of Patent: June 16, 2020Assignee: BOS GMBH & CO.

Publication number: 20190047381Abstract: Shading system having at least one flexible planar structure mounted such that it can be wound onto at least one winding shaft between a wound-on position of rest and at least one at least partially extended functional position and unwound therefrom. A plurality of strip sections extend in parallel with respect to one another and have different translucency values. A control device changes the translucency of the planar structure through spatial displacement of the planar structure. Two flexible planar structures are provided and are displaceable in parallel or transversely. Each planar structure is provided with strip sections which run longitudinally or transversely and have different translucency values. The control device acts mechanically on at least one planar structure and has at least one manually-operated actuator element.Type: ApplicationFiled: January 17, 2017Publication date: February 14, 2019Inventors: Jan LEKAR, Michele TINA

Publication number: 20160303950Abstract: Protective device for a vehicle interior including a flexible two-dimensional structure held on a winding shaft and movable between a pulled-out protective position and a rest position wound-up on the winding shaft. The winding shaft is driven by a motor in both directions of rotation, wherein the two-dimensional structure is provided with a dimensionally stable pull-out profile in the end face region that is in front in the pull-out direction, and a drive transmission arrangement is provided which engages the pull-out profile and is in operative connection with the winding shaft. The winding shaft is associated with a blocking device which is, by control device, movable between a release position, releasing the winding shaft for rotational movement, and a securing position, blocking rotational movement of the winding shaft, in response to a displacement condition of the pull-out profile.Type: ApplicationFiled: April 7, 2016Publication date: October 20, 2016Inventor: Jan LEKAR

Patent number: 9132718Abstract: A shading device for a glass surface region of a motor vehicle having a flexible shading formation movably supported between a rest position compactly stored in a vehicle interior and a tensioned shading position. The shading device includes a dimensionally stable draw-out profile member movable by a linearly movable lifting rod into the shading position or the rest position. A drive unit for lifting or lowering the lifting rod is associated with the lifting rod. The draw-out profile member has a support receiving member, which is closed upwards in the lifting direction and which is open downwards, for receiving and releasing the lifting rod in accordance with the movement direction of the lifting rod. A locking device is associated with the draw-out profile member and secures the draw-out profile member in the shading position so as to be fixed to a vehicle.Type: GrantFiled: June 27, 2014Date of Patent: September 15, 2015Assignee: BOS GMBH & CO.

Patent number: 7581775Abstract: A roller blind for a side window of a motor vehicle. The roller blind has a winding shaft, which is coupled via an articulated or flexible coupling mechanism to a spring drive situated outside the winding shaft. The winding shaft and the spring drive are accommodated inside a vertical window frame segment of a motor vehicle's window. The articulated or flexible coupling between the winding shaft and the spring drive makes it possible to approximate a curved path by means of two normally straight elements of the blind. Furthermore, a very flat characteristic tension curve can be achieved for the spring drive, even when the winding shaft is very short.Type: GrantFiled: August 8, 2007Date of Patent: September 1, 2009Assignee: Bos GmbH & Co.
