This application is claims benefit of Serial No. 157/MUM/2012, filed 17 Jan. 2012 in India and which application is incorporated herein by reference. To the extent appropriate, a claim of priority is made to the above disclosed application.
The present invention relates to a sun visor, more particularly the present invention relates to a sun visor system for occupant of a vehicle, allowing for a panoramic windscreen.
In an automobile, sun visors are provided to shield driver and passenger from direct sunlight under conditions when the sun is at the horizon. Such conditions can compromise the driver's ability to discern objects in front of the car and will constitute a hazardous situation.
Hence, to shield the driver and passenger's vision path, the position of the sun visor is constrained to a band that is dictated by ergonomics. The visor is typically affixed at the point where the roof and front windscreen join and thus constraints position, size and placement of the sun visor.
In vehicle design, it would be desirable to extend the top of the windscreen above the driver and passenger heads to allow for a “panoramic” windscreen that would have the following advantages:
However, as mentioned above, the roof and windscreen top, constrain the position of the sun visor. Another limitation of the “panoramic” windscreen is it potentially allows direct sunlight to impinge the vehicle cabin. This has adverse effect on the occupants, and cabin heating/cooling, which therefore needs to be addressed.
Thus, there is need in the art that overcomes these constraints or limitation by allowing the sun visor to be mounted directly to the windscreen and a sunshade that can be pulled into place and then retracted as and when needed.
The principal object of the present invention is to provide a system adapted to provide sun visor protection to the occupant the vehicle while allowing for a panoramic windscreen that curves into the roof.
Another object of the present invention is to provide a system that will allow for enhancing aerodynamics of a vehicle without reducing occupant comfort.
Another object of the present invention is to provide a system that enables an occupant of a vehicle to control viewing angle for the occupants of the vehicle.
Another object of the invention is to provide a system comprising a centre pod fixed in the centre of the glass and adapted to configure the sun visor. The pod further comprises an interior light.
Yet another object of the invention is to provide a system wherein the sun screen and sun shade do not interfere with the upward visibility line of 14 degree from the horizon.
Another object of the invention is to provide a system comprising the sunscreen adapted to fully deploy along with the sun visors forming complete sun block with no leakage.
Another object of the invention is to provide a system for blocking direct sunlight from the occupants of a vehicle and allowing controllable viewing angle therefrom the vehicle to each passenger.
Another object of the invention is to provide a system further provides configurable independent sunlight blocking or completely unobstructed options for the occupants in a vehicle with a panoramic view windscreen.
Another object of the invention is to provide a sun visor adapted to deploy by a combination of two movements:
It is to be understood that both the foregoing general description and the following detailed description of the present embodiments of the invention are intended to provide an overview or framework for understanding the nature and character of the invention as it is claimed. The accompanying drawings are included to provide a further understanding of the invention and are incorporated into and constitute a part of this specification. The drawings illustrate various embodiments of the invention and together with the description serve to explain the principles and operation of the invention.
The present invention relates to a system for controllable viewing angle and independent sunshade provision there from the vehicle to each passenger of a vehicle equipped with a panoramic windscreen, the system comprising of a windscreen extending from a base of a hood up to a predetermined length of a roof, the said continuous windscreen comprising a curved radial surfaces adapted to offer negligent kinematic obstruction to the vehicle assembly and lateral edges thereof supported with a pair of angulated post inclined in a first plane; a sun visor disposed on a pod wherein the pod is glued on the inner wall of the windscreen; a plurality of track, laid parallel to each other are deployed on an inner wall of the windscreen; and a retractable sunshade located on the plurality of track.
In another aspect of the invention, a system is provided which is adapted to enable a standard sun visor to allow for panoramic windscreen when retracted by the occupants of the vehicle.
Yet another aspect of the invention is to provide the sun visor adapted to deploy by a combination of two movements:
The above-mentioned and other features and advantages of the various embodiments of the invention, and the manner of attaining them, will become more apparent and will be better understood by reference to the accompanying drawings, wherein:
As used in this specification and claims, the terms “for example,” “for instance,” “such as,” and “like,” and the verbs “comprising,” “having,” “including,” and their other verb forms, when used in conjunction with a listing of one or more components or other items, are each to be construed as open-ended, meaning that that the listing is not to be considered as excluding other, additional components or items. Other terms are to be construed using their broadest reasonable meaning unless they are used in a context that requires a different interpretation.
It must also be noted that as used herein and in the appended claims, the singular forms “a,” “an,” and “the” include plural references unless the context clearly dictates otherwise. Although any apparatus, methods, apparatuses, and devices similar or equivalent to those described herein can be used in the practice or testing of embodiments of the present invention, the preferred, apparatus and parts are now described. The disclosed embodiments are merely exemplary of the invention, which may be embodied in various forms.
The disclosed embodiment “a windscreen” is similar or equivalent to “a windshield” in the vehicle.
In the disclosed embodiment “a system” is similar or equivalent to “an assembly” of the invention.
The present invention provides a system for controllable viewing angle and independent sunshade provision there from the vehicle to each passenger of a vehicle equipped with a panoramic windscreen, the system comprising of a windscreen extending from a base of a hood up to a predetermined length of a roof, the said continuous windscreen comprising a curved radial surfaces adapted to offer negligent kinematic obstruction to the vehicle assembly and lateral edges thereof supported with a pair of angulated post inclined in a first plane; a sun visor disposed on a pod wherein the pod is glued on the inner wall of the windscreen; a plurality of track, laid parallely are deployed on an inner wall of the windscreen; and a retractable sunshade located on the plurality of track.
Referring to
According to one embodiment of the invention the system (100) is adapted for enabling independent sunlight blocking or completely unobstructed options for the occupants in a vehicle with a panoramic view windscreen.
According to another embodiment of the invention the system (100) integrates the sun visor (102) and the sun shade (104) to provide a complete screening mechanism.
According to an embodiment of the invention, a continuous windscreen extends from a base of a hood up to a predetermined length of a roof; the continuous windscreen comprises a curved radial surface adapted to offer negligent kinematic obstruction to the vehicle assembly and lateral edges thereof supported with a pair of angulated post inclined in a first plane. In a preferred embodiment of the invention, the windscreen is supported continuously by its edges to the vehicle structure by use of an adhesive.
In another embodiment of the invention, the sun visor (102) is adapted for a motion in a direction as referred by 2 and 3 in
Further, the sun shade (104) is adapted for a motion as illustrated reference 5 in
