Definitions

  • This invention relates to sunvisors used in trucks and automobiles. More particularly, this invention relates to a sunvisor that has an adjustable shade region.
  • a common problem with the current sunvisors for trucks and automobiles is that they cannot shade against light coming from certain directions. More specifically, they cannot block light entering an automobile windshield in the region of a central rear view mirror or to the extreme right or left of a windshield.
  • a standard sunvisor when pivoted to the side, usually does not extend back far enough to block out the light from the driver's or passenger's eyes and generally leaves the area behind the windscreen/door pillar exposed. This is particularly relevant when driving on a winding road when the suns glare is alternately coming from the front, the side and the area in between.
  • One prior art device currently in use and marketed through the J C Whitney Company (see Figure 1(b)), includes an aftermarket main panel 216 that attaches to an existing sunvisor 217 and has independent panels 218 and 219 that can be manually extended out from the left or right, and the bottom side.
  • it has to be manually operated which means that a driver must, at a time when all his attention is needed because of limited visibility due to sun glare, take one hand off the steering wheel and look up momentarily to extend the panels.
  • the extendable panels 218 and 219 do provide increased shade protection, they are not sufficient to protect against light approaching from the area behind the windshield/door pillar at approximately 45° to the direction of travel.
  • the product is manufactured from a rigid, semi-transparent injection moulded plastic/perspex type of material that could splinter on impact causing injury to head or eyes. The result is that it would not pass current safety standards in most countries.
  • FIG. 2 Another prior art device, currently offered in the Mercedes Benz S-class vehicles, is a standard type sunvisor 220 that can be manually positioned laterally once removed from a mounting clip 221 as shown in Figure 2.
  • This sunvisor again has the problem of requiring a driver to divert his attention momentarily when adjusting the visor, does not protect against sunlight approaching from 45° as in the previous example, and can only be positioned laterally when removed from the mounting clip 221.
  • This secondary sunvisor can be pulled down when the primary sunvisor has been turned to the side. This does not however solve the problem of the primary sunvisor generally being too short to cover all of the required side window area, particularly for a taller driver having the seat well back, nor does it adjust to cover either the area behind the central rear vision mirror or the corner behind the windshield/door pillar area.
  • Mercedes Benz also employ a small, secondary sunvisor behind the rear vision mirror, but similarly, it does not solve all of the problems mentioned above.
  • a sunvisor that can be extended to provide simultaneous front, diagonal, and side shade protection. In other words, it is desirable to simultaneously protect against light entering from the front windshield area, the area where the front windshield meets a side window, and a side window. What is also needed is a sunvisor which can be either automatically adjusted using heat or light sensors, or electronically adjusted by a user without taking his hands off the steering wheel.
  • the present invention aims to provide greater control to a user over the shade protection offered by a car's existing sunvisor.
  • a sunvisor can increase the area of shade protection by allowing the user to expand its length. This can be accomplished by use of bendable light obscuring panels which can be extended from the sunvisor and provide simultaneous front, diagonal, and side shade protection, or by a telescoping sunvisor which has a variable length.
  • the sunvisor can also be designed to allow the user to laterally move the area of shade protection. This is preferably accomplished using a motor to electronically move the sunvisor laterally.
  • the present invention provides:-
  • a sunvisor for attachment to an existing sunvisor, the existing sunvisor coupled to a vehicle, and having a first position and a second position, comprising

  • a user can control the amount of shade protection by increasing the length of the sunvisor.
  • the sunvisor is comprised of a hollow panel 2 and two bendable light obscuring panels 6 and 7 which can manually be extended laterally out from the hollow panel 2. Tabs 23 and 24 help a user to grasp the panels 6 and 7 upon extension.
  • the hollow panel 2 can be attached to a vehicle's existing sunvisor by means of two double sided adhesive strips 31 and 32.
  • Figure 6 shows an overhead view of a sunvisor 211 with the hollow panel 2 (as described in Figures 3 - 5) in use by a driver 215 against a front windshield 205 with the bendable light obscuring panel 6 extended across a side window 210, forming a smooth arc 206.

The friction between the bendable panels 6 and 7 and the hollow panel 2 prevents tension in the bendable panels 6 and 7 from forcing the bendable panels 6 and 7 back into the hollow panel 2.

Abstract

L'invention procure à son utilisateur un meilleur contrôle de la protection contre l'éblouissement offerte par le paresoleil existant d'un véhicule. Le paresoleil inventé permet d'accroître la zone protégée lorsque l'utilisateur en accroît la longueur. Ceci est dû à des panneaux souples atténuant la lumière que l'on peut déployer depuis le paresoleil pour obtenir simultanément une protection anti-éblouissement frontale, diagonale et latérale, ou à un paresoleil télescopique à longueur variable. Ce paresoleil est également conçu pour que l'utilisateur déplace latéralement la zone de protection ou pour une combinaison de deux des procédés mentionnés ci-dessus ou plus. De préférence, ceci est possible par l'utilisation d'un moteur qui déplace latéralement le paresoleil par le biais d'un dispositif électronique.
