Description

[0001] The present invention is a device on sun visors in motor vehicles which serves to increase driving safety in automobiles. Description of the invention

[0002] Sun visors are a familiar feature of every motor vehicle. They typically have a defined length, which can depend on the space available in the roof lining and other factors. Sun visors are typically designed so that they can be folded down to various angles as needed (e.g., when the sun is glaring), and then, after unlocking the mount on the interior rearview mirror, pivoted toward the side window. Despite the described repositioning, the length (meaning the length of the long side) of the existing sun visor is often insufficient to adequately cover the sun glare from the front and sides at the level of the sun visor.

[0003] Example of sun from the front: Often, after folding down the conventional sun visor, there is a gap of a few centimeters between the A-pillar and the interior mirror, so that the sun can continue to dazzle at the level of the short side of the sun visor despite the sun visor being folded down.

[0004] Example of sun from the side: Very often, when the sun visor is folded down and swung to the side, there are several centimeters missing from the B-pillar in the vehicle, so that the sun can continue to dazzle at the level of the short side of the sun visor.

[0005] Installing longer rigid sun visors in motor vehicles is often not possible due to the limited space on the roof of the vehicle. They may cover too much of the interior mirror when folded down and could unnecessarily obstruct the head and upper body of the driver or front passenger sitting in the vehicle when swung to the side.

[0006] The present invention is based on the object of creating a resettable device in accordance with the existing - mostly too short - sun visors, the elements of which make it possible to better cover the sunlight of the glare from the front or from the side.

[0007] The problem is solved with the features of claim 1, wherein the subclaims describe further embodiments.

[0008] This object is achieved according to the invention by at least one additional sun visor element (hereinafter also called extension element) arranged movably relative to the sun visor with the features of patent claim 1. Implementation of the invention

[0009] The invention is explained using 7 mechanical and manually operated embodiments.

[0010] Four drawings are included for each example. Each shows a sun visor mounted to the left of the interior mirror on the roof of the vehicle. The sun visor is folded down in the upper part of the drawings, and the lower part is folded down and also pivoted to the side.

[0011] The material for the invention should be sufficiently stiff, yet flexible, so that it can easily butt against the edges of the A and B pillars of the vehicle and the interior rearview mirror without snagging or sticking there. The material should be at least thick enough to be opaque. The same opaque materials as for the sun visors themselves can be used for manufacturing. Rubber or rubber-like materials, plastics, (woven) fabrics, leather, or cardboard are also possible. The protruding edges of the extension elements should be rounded to reduce the potential risk of injury at head and eye level.

[0012] The inventions could be integrated or installed directly into or onto the sun visors during the production of new motor vehicles, or subsequently added to or onto the sun visors of vehicles already in production. Or the conventional sun visors could be completely replaced with sun visors incorporating the invention.

[0013] For the technical implementation of the invention, the following variants are described in more detail as examples: - Sliding mechanism (variant A, variant B and variant C) - Rotating mechanism (variant D and variant E) - Folding or swivel mechanism (variant F) - Extension mechanism (variant G) List of reference symbols 11 fixed headliner bracket 12 removable headliner brackets 13 outer layer of the sun visor 14 inner layer of the sun visor, partly covered by 15 15 Extension element 16 “window opening” with a view of 13 or 14 or 15 17 Rail 18 Axis perpendicular to the sun visor 19 Axis in the plane of the sun visor 20 banderols 21 Handle or recessed grip

[0014] The Fig. 1 and Fig. 2 a drawing example of variant A.

[0015] At least one sliding extension element is installed in the sun visor below a window opening. This extension element can be operated from the top or bottom of the sun visor. It can be pushed out and retracted, or pulled out and retracted, through a side opening on one of the short sides of the sun visor. The extension element runs internally on at least one guide rail attached to the sun visor. It can be operated using a handle or recessed grip attached to the movable part, or directly with the fingers (without a handle or recessed grip).

[0016] (The extension element could be stopped by mechanical resistance on the sun visor or the guide rail. Connecting the extension element to the sun visor via the guide rail prevents the extension element from falling off.)

[0017] The Fig. 3 and Fig. 4 a drawing example of variant B.

[0018] At least one extension element consisting of a sliding part and a fixed part is attached to the top and bottom of the sun visor. The parts are connected by at least one guide rail. The fixed part (which can also just be the guide rail) is attached to the sun visor (e.g., glued, clamped, screwed, or riveted). The sliding part has a handle or recessed grip, or can be operated with the fingers using friction. It preferably runs in at least one guide rail. It should be adjustable to a maximum extension length, stop when the target is reached, and cannot fall off.

[0019] (The extension element should be stopped by a mechanical resistance on the sun visor or the guide rail. Connecting the extension element to the sun visor via the guide rail prevents the extension element from falling off.)

[0020] The Fig. 5 and Fig. 6 a drawing example of variant C.

[0021] By using a band around the conventional sun visor, at least one gap is created between the sun visor on the top and the band, or between the sun visor on the bottom and the band. This gap, or at least one of these gaps, can be used for at least one extension element. The extension element is inserted as a movable disc into the space between the sun visor and the band and can be pushed or pulled out of the band to the sides using a handle or recessed grip, or with the fingers using static friction. The extension elements should ideally be longer than the width of the band and no longer than the length of the sun visor.

[0022] (The movable extension element should be prevented from falling by a mechanical resistance on the sun visor or the band. To prevent the extension element from tipping over during extension, at least one guide rail connecting the extension element to the band and the sun visor is sensible and useful.)

[0023] The Fig. 7 and Fig. 8 a drawing example of variant D.

[0024] At least one extension element is inserted inside the sun visor in a rotatable manner - for example on an axle - which can be operated from the top or bottom of the sun visor and can be rotated in and out through a side opening on one of the short sides of the sun visor. The rotatable extension elements can run in guide rails inside the sun visor or be rotatably attached to an axle perpendicular to the sun visor. The axle or guide rails are firmly connected to the sun visor. The extension elements can be operated via the axle protruding from the sun visor, by a handle or recessed grip attached to the movable part, or by static friction directly with the fingers (without a handle or recessed grip).

[0025] (A braking mechanism using mechanical resistance would be useful. The firm connection of the rotating extension elements to the axle or guide rail prevents the extension elements from falling off.)

[0026] The Fig. 9 and Fig. 10 a drawing example of variant E.

[0027] At least one rotating extension element is attached to the top and bottom of the sun visor, preferably on a pivot. The rotating extension element can run on guide rails attached to the outside of the sun visor or be rotatably mounted on a vertical pivot attached to the sun visor. Operation can be achieved via the pivot protruding from the sun visor, by a handle or recessed grip attached to the movable part, or by friction directly with the fingers (without a handle or recessed grip).

[0028] (The axle or guide rail, which is firmly attached to the sun visor (e.g., glued, clamped, screwed, or riveted), simultaneously prevents the extension element from falling off. A braking mechanism with a mechanical resistance would be useful.)

[0029] The Fig. 11 and Fig. 12 a drawing example of variant F.

[0030] At least one extension element is attached to the top and bottom or to the edges of the short sides of the sun visor. It consists of a folding or pivoting element and, in this example, is attached to an axis fixed to the sun visor parallel to the short side of the sun visor or to a hinge. The axis of rotation is in the plane of the sun visor. The folding or pivoting part has a handle or recessed grip, or can be operated with the fingers using static friction. The mechanical resistance to continuous or detent rotation at the axis of rotation or on the hinge must be at least high enough to prevent the extension element from accidentally hanging vertically due to gravity.

[0031] (The folding or pivoting axis or hinge should be firmly connected to the sun visor (e.g., glued, clamped, screwed, or riveted) to prevent the extension element from falling off.)

[0032] The Fig. 13 and Fig. 14 a drawing example of variant G.

[0033] The sun visor is extended by pulling apart a section of the sun visor along at least one fixed internal guide rail. The limits of the short sides and external boundary surfaces of the sun visors could correspond to the limits of the extension element. Operation can be achieved using a handle or recessed grip attached to the movable part, or by static friction directly with the fingers (without a handle or recessed grip). Alternatively, unlocking can be achieved by pushing the extension element forwards against a spring pressure. When the resettable sun visor element is pulled out, at least enough of the central section of the sun visor remains to ensure the stability of the sun visor and its opacity.

[0034] (The connection of the extension element via the guide rail also prevents the extension element from falling off.) Important note on the AG variants listed above:

[0035] Since the previously described variants of the resettable devices on sun visors in motor vehicles are exemplary embodiments, they can be modified to a wide extent by a person skilled in the art without departing from the scope of the invention. In particular, the specific embodiments of the resettable devices on sun visors in motor vehicles can also be implemented in a form other than that described here. Likewise, the device on the sun visor in motor vehicles can be implemented in a different form if this is necessary for reasons of space or design reasons. Furthermore, the use of the indefinite articles "a" or "an" does not exclude the possibility that the features in question may be present multiple times.
