The cassette is slidably mounted on a track (4) for movement to either sides of the existing sun visor. The sun visor is usable in automobiles or other vehicles.

Description

Auxiliary Sun Visor

The invention relates to an auxiliary sun visor for use in passenger cars as well as in other relatively large or small vehicles. In particular, the invention relates to an auxiliary sun visor integrated into a sun visor for protedtion against blinding by the sun or for mounting on a sun visor on any side of the latter.

Under conditions of facing light, e.g. when the sun is low, it has proved that existing sun visors in contemporary cars do not, in general, offer sufficient protection against blinding. This is a known and highly troublesome problem, entailing also a danger to traffic, especially in case of persons of small height and such as are of average height.

Patents and patent applications concerning arrangements for mounting on or integration into sun visors and extensible in one or several directions are already known. All these arrangements have this in common that they are intended to solve the same problem, whereas the means for achieving such a solution differ.

US patent 3.336.072 relates to an arrangement for extending the sun visor vertically and horizontally with the aid of a transparently tinted plate. A good pair of sun glasses could serve the same purpose. Besides, the method according to which this sunvisor is attached causes the latter to be deformed and worn after repeated sideways operation of the arrangement. Furthermore, the sideways operation will also be restricted, inter alia as a result of the ways in which the sun visors of the various cars are designed.

US patent 2.941.839 shows an arrangement which can be folded down and at the same time moved sideways. Sideways operation of the arrangement requires special attention while driving - an aspect which may impair traffic safety. The method of attachment which, inter alia, comprises springs, entails the danger of the sun visor becoming worn/deformed, while at the same time being unsightly. US patent 4.736.979 shows a principle for screening the sun downward and sideways within the limits of the sun visor. The methods for attaching the mountable type are cumbersome, and if use is made of screws the sun visor will, in addition, be impaired once the arrangement is removed. If use is made of fastening clips the latter may give rise to deformation, and in the most unfavourable case the arrangement may drop off while driving.

The British patent application published under No. 2.090.570 shows a system for screening which consists of a sun visor with built-in extensible plates. Sideways operation of the sun visor can be effected manually, by means of a motor or by a combination of photo cell and motor. In certain situations it is necessary for sun visors in vehicles to be amenable to rapid operation so as to achieve the required protection against blinding by the sun. Motor-controlled arrangements for such a purpose will satisfy such requirements with difficulty. Furthermore, this known system will be both costly and complicated to manufacture, and it will not perform the intended function.

With the present invention, the auxiliary sun visor constitutes a construction which by its simplicity entails a considerable improvement by comparison with what is known, as regards meeting the requirements concerning function, operating comfort, design, simple assembly, suitability for most cars and simple and economic production.

With the auxiliary sun visor according to the invention it is possible to protect oneself better against e.g. blinding by the sun, while the auxiliary sun visor can, according to requirement, be operated downward and at the same time also sideways in a single manual operation, so that the protection is quickly directed to wherever it is needed.

According to the invention, the initially mentioned auxiliary sun visor for integrating into a sun visor is characterised by a plate which is guided in a track and can be drawn downward and out from a cassette with a built-in friction means such as friction taps, while the cassette can, at the same time, be moved sideways in any

direction along a slide track, said slide track constituting an integral part of the sun visor.

The auxiliary sun visor for mounting on a sun visor is characterised in that a plate guided in a track can be drawn downward and out from a cassette with built-in friction means such as friction tape, at the same time as the cassette can be moved sideways in any direction along its slide track and in that the slide track has attached to its rear a first bur lock component with a view to co-operating with a second bu: lock component glued to the sun visor. In accordance with a further feature of these two types of auxiliary sun visor, the slide track may be provided with at least one recessed area for accommo- dating an information label which comes into view when-the cassette is moved to one side or the other.

As regards the mountable type of the invention, it is, in addition, possible for mounting to be effected in a very simple manner on any side of the sun visor, by simply pulling off the backing for the adhesive on the rear of the second bur lock component and placing the auxiliary sun visor directly on the sun visor in such a way that the latter can be used immediately. With this method of mounting it is possible for the auxiliary sun visor to be removed in its entirety, with the second bur lock component remaining on the sun visor while the first bur lock component remains firmly attached to the rear of the slide track. The fastening arrangement (bur lock) offers the user an additional possibility for vertical adjustment/extension.

The recessed area on the slide track of the auxiliary sun visor, which comes in view during sideways displacement, is capable of accommodating a label showing an emergency telephone number etc. This is an important detail which may be of value, e.g. in case of accidents etc. The invention contributes to a considerable improvement of traffic safety and to the possibility of ensuring continuous driving comfort. Practical trials using prototypes in passenger cars have shown this to be the case. Fig, 1 shows a sun visor with integrated auxiliary sun visor, according to the invention.

Fig. 2 shows a sun visor with an auxiliary sun visor according to the invention mounted on.

Fig. 3 shows a cassette on an auxiliary sun visor pulled sideways and with the auxiliary sun visor plate pulled down from the cassette. Fig. 4 illustrates in side view a cassette with slide track, with the auxiliary sun visor plate partly pulled out of the cassette.

Fig. 5 illustrates in side view the arrangement of the bur lock for mounting of the auxiliary sun visor according to Fig. 2.

The drawing in Fig. 1 shows, according to the invention, a sun visor 1 with integrated auxiliary sun visor, also referred to as cassette 2, in the operational position, in which cassette 2 is pulled sideways along a slide track 4 integrated into sun visor 1, so that a label 9 can be seen, with plate 3 pulled down from cassette 2.

Fig. 2 illustrates cassette 2' in the operational position, said cassette being attached to a sun visor 1' with the aid of a bur lock and pulled sideways along a slide track 4' in such a way that a label 5 comes into view, a plate 3' being pulled downward.

Fig. 3 shows a front view of a cassette 2 or 2' pulled sideways along slide track 4 or 4'. Plate 3 or 3' is guided in track 6, 7 or 6', 7' on the corresponding plate and on the inside of the cassette and maintained in the required position by the built-in friction on the rear of cassette 2 or 2', with a front piece, e.g. in the shape of a silicone-coated friction tape 8 or 8'. Fig. 4 shows a side view of cassette 2 according to the embodiment shown in Fig. 2, with plate 3 partially pulled out of cassette 2 and with slide track 4, which is an integral part of sun visor 1, removed from cassette 2.

Fig. 5 shows, in diagrammatic form and in side view, the way in which an auxiliary sun visor is attached to an existing sun visor 1'.

Cassette 2' with plate 3' is introduced into a slide track 4'. A first bur lock component 9 is attached to the rear of slide track 4' by pulling backing paper 9' from the adhesive side of bur lock component 9 and pressing component 9 against the rear of slide track 4'. In corresponding manner, a second bur lock component 10 is attached to the existing sun visor 1' by pulling off a backing paper 10' so that the adhesive side of component 10 may be attached to the surface of sun visor 1'. It may be advisable to leave the two bur lock components connected during the process of mounting on slide track 4' and sun visor 1', respectively.

According to the invention this is achieved inasmuch as a non-trans- parent plate can be pulled out of the integrated/mountable cassette on the sun visor. With both types, the cassette can be moved to one side or the other, irrespective of whether the plate is pulled downward or not, since it moves along a slide track, in which case.it will expose a recessed label on the slide bar. The label is intended for recording an emergency telephone number etc. The entire mountable type according to the invention is attached directly to an existing sun visor on any side thereof, use being made to this end of the adhesive on the bur lock when a protective strip thereof is removed. In this way simple and rapid mounting on the sun visor is enabled, as well as also equally simple and rapid dismantling, while the width of the bur lock offers an additional possibility for adjusting and placing the auxiliary sun visor on the sun visor.
