Low Profile Visor Assembly

In today's automobile styling there is a tendency to reduce the height and streamline the body of the automobile to reduce wind drag and, in turn, increase the performance and fuel economy. As the roof of the automobile lowers, the amount of room inside for passengers decreases.

It is common practice at the present time to mount the sun visor above the windshield on the driver and passenger sides on an L-shaped pivot rod with one end projecting from a fixture fastened to the overhead of the vehicle. In use, the visor can be pivoted down around the rod in front of the face of the driver or passenger and placed over a portion of the windshield. If sunlight is coming in from the side of the vehicle, the pivot rod can be swung around to the side and the visor lowered to block out the light. In order to make either of the above adjustments, the driver and passenger have to move their heads clear of the visor. If the driver is making this adjustment at high speed, a potential for an accident is presented. The operation of the visor would be substantially improved if the visor were positioned in the vehicle so that it could be adjustably brought down to block out the objectionable sunlight without the driver or passenger having to move their heads out of the way of the visor blade. Also, the overhead area in a vehicle would be substantially increased if the conventional sun visor and pivot rod were removed.

In accordance with the present invention, a low profile sun visor is provided which is attached to the A-pillar on each side of the vehicle. A track is provided which can be concealed behind decorative material revealing only a slot in which the sun visor moves. The visor track can be attached to the A-pillar and to the overhead in the vehicle and can be bent and twisted to conform to the supporting structure. When not in use, the sun visor can be slid along the track up into the overhead of the vehicle above the headliner. When it is desired to use the sun visor, it can be adjustably pulled down from the space above the headliner to the extent needed to shield the eyes from the glare of the sun. A second sun visor can also be attached to the A-pillar on a similar track so that the sun visor can project along a side window of the vehicle. Again, when the visor is not in use, it can be stored above the headliner and, when needed, adjustably drawn downwardly in the track to the extent needed to comfortably protect the eyes of the passenger or driver of the vehicle.

Essentially, a low profile visor for a vehicle is provided which has a support track attached to a portion of the body structure. The track has a longitudinal slot in one edge with the opposed sides of the edge forming guide surfaces for the visor. A longitudinal channel is provided in at least one of the guide surfaces to receive a visor alignment member.

A visor blade is provided for covering a portion of the window through which excessive light passes. The visor has an aperture near each end of a common edge. An alignment member, preferably a ball, is inserted into each aperture in the visor. The edge of the visor, including the alignment member, is inserted into the slot in the visor track with the alignment balls in the channel in the guide surface. The visor is free to slide in the support track which can be extended along a window edge and up above the headliner of the vehicle. The visor can be stored substantially out of sight and can then be adjustably slid down to the optimum position to shield excessive light from the eyes of the driver or passenger.

Referring to FIG. 1, the basic visor assembly is shown and indicated generally by the number 20. The visor assembly has a support track 21 which has a longitudinal slot 22 therein bounded by a pair of guide surfaces 23 and 25. A longitudinal channel 27 is located in guide surface 23.

A visor blade 29 is mounted in slot 22 in support track 21. Apertures 31 and 33 are stamped or die cut into opposite corners of a common edge of visor blade 29. An alignment member 35, preferably a ball bearing, is loosely fit into each of the apertures 31 and 33. The visor blade 29, along with ball bearings 35, are inserted into elongated slot 22 in support track 21 with the ball bearings being free to roll in channel 27 as visor blade 29 moves in slot 22.

Support track 21 can be made of metal or plastic and is preferably formed through an extrusion process. The support track can easily be bent to conform to the configuration of the vehicle. For example, in mounting the support track on either A-pillar at the front of a vehicle, the support track can be mounted to the A-pillar and then extended up under the roof of the automobile and above the decorative headliner, as shown in FIGS. 3-5.

Visor blade 29 can be shaped to cover the necessary portion of the windshield or side window. The blade can be made of metal but is preferably made of plastic material. The plastic material can be tinted, polarized or opaque. Regardless of the material used to make the visor blade, it should be thick enough to be dimensionally stable so that it can maintain its position adjacent the window it is intended to cover.

In FIG. 3, a portion of an automobile 40 is shown including a dashboard 41, a windshield 43, an A-pillar 45, a door 47 and a side window 49. The A-pillar 45 has a track 51 which is concealed beneath the decorative material 53 which covers the A-pillar. A visor blade 55 is supported in track 51 and extends through a slot 56 in the material 53. The visor blade is adapted to adjustably move, as indicated by the bi-directional arrow 57, from the use position shown to a concealed position, indicated in phantom, which is above the headliner of the vehicle and below the roof. A similar concealed track 59 is also attached to the A-pillar 45. A visor blade 61 is supported in track 59 and extends through a slot 62 in material 53. The visor blade is adapted to adjustably slide from a use position, covering a portion of a side window 49, to a stored position, shown in phantom, which would be above the headliner of the vehicle and below the roof. The adjustable movement of visor blade 61 is indicated by the bi-directional arrow 63.

In view of the sharp slope of A-pillar 45, and since the visor blades are only intended to cover the portion of windshield 43 and side window 49, through which objectionable sunlight would pass, visor blades 55 and 61 are not as large as the entire window they are intended to cover. Each visor blade only has to be large enough to cover the portion through which the objectionable light would pass. In view of the reduced size of the visor blades, the visor blades can be stored above the headliner and below the roof without overlapping. It is clearly within the scope of the present invention to have the visor blades overlap.

In FIG. 4, visors 55 and 61 are shown supported in an overhead portion of the vehicle by guide support tracks 51 and 59. It can be seen that both visors are substantially out of view of the occupants of the vehicle and can be raised and lowered by merely grasping an edge portion of the visor blade.

As mentioned above, visor support track 21 is preferably made through a metal or plastic extrusion process and can be shaped to conform to the configuration of the A-pillar of the vehicle and the roof line. The visor blade material is flexible and, through the use of alignment members 35, the visor blade will smoothly conform to the turns and twists in the visor support track. As shown in FIG. 5, visor support track 21 can extend along A-pillar 45 of the vehicle and then smoothly bend under the roof of the vehicle 70 and above the headliner 71 of the vehicle so that the visor blade can be substantially removed from sight to a position where the head room in the vehicle is not interfered with.

While in FIGS. 1 and 2 the preferred visor alignment member is shown to be a ball bearing 35, it is within the scope of the present invention to use other alignment member configurations. Referring to FIG. 6, a plastic alignment member is shown which can be fixed in an aperture 73 which extends through a corner portion of a visor 75. The alignment member has an upper part 77 which has a substantially centrally disposed projection 79 which can be press-fitted into a blind hole 81 formed in the abutting surface of a second half of the alignment member 83. In use, the two halves of alignment member 77 and 83 can be press-fitted together in the corner of visor blade 75. The plastic alignment member can be made of a material such as Nylon or Teflon, which are lubricious materials which can easily slide in the guide channel in the visor support track.

In FIG. 7, the alignment member 85 is in the form of a roller. The roller is inserted into a substantially rectangular aperture 87 in a corner of the visor blade 89. The rectangular aperture maintains the alignment of the roller preventing it from cocking or locking rather than rolling smoothly in the guide channel in the visor support track. Roller 85 can be made of metal or plastic.

In FIG. 8, a visor guide track 91 is shown having an alignment channel 93 formed in both the upper and lower guide surfaces 95 and 97, respectively. An alignment member in the form of a ball bearing 99 is positioned in the guide channel in an aperture in a visor blade 101. As mentioned above, a pair of alignment members would be used along one edge of the visor blade. The number of alignment members can be increased as desired. At least two are preferred near remote corners along a common edge of the visor blade.

Now referring to FIG. 9, a visor guide track 103 is shown with a single guide channel 105 formed in one guide surface 107. An alignment member in the form of a ball bearing 109 is confined within guide channel 105 and can freely roll along guide surface 107. While substantially rectangular guide channels have been shown in the visor track, it is within the scope of the present invention to use other channel configurations. For example, arcuate or abutting angled surfaces forming a substantially V-shaped channel can also be used. The guide channel and alignment members provide for easy movement of the visor blade in the support track with the visor blade being stiffened by the guide surfaces adjacent the alignment channel. The visor blade is then free to move in the visor support track while being maintained in alignment with the edge of the visor blade reinforced by the guiding surfaces on either side of the longitudinal slot in the guide track.

From the above description it can be seen that a low profile visor is provided for use in a vehicle which can be substantially completely removed from sight of the driver and passengers of the vehicle and which can easily be grasped and adjustably slid down over the windshield or side window to provide protection from objectionable sunlight. The low profile visor assembly also removes the pivot rod and its support bracket providing more head room for the occupants of the vehicle. The low profile visor also provides unlimited adjustability in the amount of windshield or side window being covered rather than the substantially all or nothing provided by the conventional visor assembly.

Though the invention has been described with respect to a specific preferred embodiment thereof, many variations and modifications will become apparent to those skilled in the art. It is therefore the intention that the appended claims be interpreted as broadly as possible in view of the prior art to include all such variations and modifications.
