Description
AUSTRALIA
Patents Act 1990 COMPLETE SPECIFICATION Standard Patent Applicant(s): SCHEFENACKER VISION SYSTEMS FRANCE Invention Title: Method for increasing the field of vision in the mirror of a vehicle outside rearview mirror assembly, and vehicle on which said method is implemented The following statement is a full description of this invention, including the best method for performing it known to us: -2- METHOD FOR INCREASING THE FIELD OF VISION IN THE MIRROR c OF A VEHICLE OUTSIDE REARVIEW MIRROR ASSEMBLY, AND SVEHICLE ON WHICH SAID METHOD IS IMPLEMENTED 00 I 5 The present invention relates to a method for increasing the field of vision in the mirror of an 00 outside rearview mirror assembly fastened on at least
\O
00 one side of a vehicle, especially an automobile.
C-I 10 According to the regulations currently in force, the Sfield of vision in the mirror of outside rearview C-I mirror assemblies of an automobile must be large enough so that the driver can see, on each side of the vehicle, a plane horizontal road portion extending over 4 metres in width from 20 metres to the rear of the vertical plane passing through his ocular points, as far as the horizon.
The driver must also be able to start to see the road over a width of 1 metre from 4 metres to the rear of the vertical plane passing through his ocular points.
One solution to meet the current regulations consists in increasing the dimensions of the mirror of outside rearview mirror assemblies.
However, this solution requires the fitting of bulkier and heavier rearview mirror assemblies, which have the drawback of increasing the drag coefficient of vehicles, promoting vibration generation and being expensive because of the fold-back mechanisms that they have to be provided with in order to meet the pendulum impact test.
The object of the present invention is to meet the current regulations without increasing the dimensions of outside rearview mirror assemblies and, to do so, the subject of the invention is a method for increasing N \Melbourne\Caes\Patent\71000-71999\P71625.AU\Specio\P71625.AU GH Specidoc 28/02/07 3 the field of vision in the mirror of an outside rearview mirror assembly fastened on at least one side Sof a vehicle, especially an automobile, this method being characterized in that it comprises the steps 00 C 5 consisting in equipping the rearview mirror assembly with a convex spherical mirror having a radius of 00 curvature of the order of 120 to 135 cm and in
\O
00 fastening this rearview mirror-assembly to the vehicle in such a way that the distance between the centre of its mirror and the middle of the segment connecting the driver's eyes, as projected on the longitudinal axis of C-I the vehicle, is of the order of 20 to 40 cm.
Thanks to these steps, that part of the road defined by the current regulations can be seen completely in the mirror of an outside rearview mirror assembly of conventional dimensions.
The regulations can therefore be met by outside rearview mirror assemblies that remain compact and relatively lightweight, thereby avoiding an increase in drag coefficient of vehicles and reducing the risk of generating vibrations.
The method according to the present invention also eliminates the blind spot in current outside rearview mirror assemblies and consequently increases road traffic safety conditions.
Preferably, the rearview mirror assembly is fastened to the side of the vehicle so that the distance, as measured vertically, between the centre of its mirror and the middle of the segment connecting the driver's eyes is of the order of 0 to 40 cm.
In this case, the rearview mirror assembly used may have even smaller dimensions, thereby enabling it to N3\Melbourne\Caes\Patent\71000-71999\P71625.Au\pecis\P7165.AU G Speci.doc 28/02/07 -4perform an even smaller projection on the body of the vehicle.
0According to one particular embodiment, the mirror of 00 C 5 the rearview mirror assembly may be made of glass and may have a radius of curvature of the order of 130 to 00 135 cm.
\O
00 As a variant, it may be made of plastic and have a radius of curvature of the order of 120 to 125 cm.
Ci When the mirror of the rearview mirror assembly is made of plastic, the moulding process employed allows it to be produced with more precise dimensions than those of a glass rearview mirror.
In fact, the radius of curvature of the plastic mirror may be smaller than that of a glass mirror because the manufacturing variation is smaller in the case of plastic products than for glass products.
Advantageously, the rearview mirror assembly projects from the vehicle by less than 10 cm.
Consequently, its cost may remain relatively low since it may require no fold-back means.
When the vehicle has front doors comprising a metal door triangle, the rearview mirror assembly may have a base fastened to the triangle of the front door located on the driver's side or on the passenger's side.
As a variant, when the vehicle has front doors with a transparent quarter pane, the rearview mirror assembly may have a transparent base fastened to the quarter pane of the front door located on the driver's side or on the passenger's side.
N \Melbourne\Casee\Patent\71000-71999\P11625.AU\Specie\P71625.AU CH Specidoc 28/02/07 To implement the method according to the invention, two rearview mirror assemblies may of course be fastened, Sone on the driver's side and the other on the passenger's side.
00 c- The present invention also relates to a vehicle, 00 particularly an automobile, on which the above method
\O
00 is implemented.
1 0 Several ways of implementing the method according to Sthe present invention will be described below as non- C-I limiting examples and with reference to the appended drawings in which: Figure 1 is a schematic top view of an automobile showing the road portions that have to be seen by the driver in the outside rearview mirrors; Figure 2 is a schematic perspective view of an automobile on which the method according to the invention is implemented and the outside rearview mirror assembly of which, located on the driver's side, allows him to see the corresponding road portion defined by the regulations in force; Figure 3 shows the field of vision in the mirror of the outside rearview mirror assembly located on the driver's side of the automobile visible in Figure 2; Figure 4 is a partial perspective view showing a front door of an automobile on which the method according to the invention is implemented, this door being located on the driver's side and comprising a metal triangle to the lower part of which a rearview mirror assembly is fastened, allowing the statutory road portion to be seen; Figure 5 is a partial perspective view that differs from Figure 4 in that the rearview mirror assembly is fastened to the upper part of the triangle, and Ni\Melbourne\Case\Patent\71000-71999\P71625.AU\Specis\P71625.AU GH Specidoc 28/02/07 6 Figure 6 is a schematic side view of an automobile on which the method according to the Sinvention is implemented.
00 C 5 Referring firstly to Figures 1 and 2, it will be recalled that the regulations in force require the 00 driver to be able to see, in the outside rearview
\O
00 mirror assemblies 1, on each side of the vehicle, a road portion R extending over 4 metres in width from metres to the rear of the vertical plane passing Sthrough his ocular points, as far as the horizon.
The regulations also require that the driver be able to start to see the road over a width of 1 metre from 4 metres to the rear of the vertical plane passing through his ocular points.
In Figure 2, the road portion that must be visible in the outside rearview mirror, on the driver's side, is defined, on the one hand, by a quadrilateral comprising a side AB perpendicular to the longitudinal axis of the automobile and having a length of one metre, a side DC parallel to the side AB and having a length of 4 metres, a side AD lying along the extension of the driver's side of the automobile, and a side BC making an angle different from 900 with the sides AB and DC, and by a rectangle 4 metres in width extending beyond the side DC, as far as infinity.
Figure 3 shows the road portion as it appears in the mirror of the outside rearview mirror assembly located on the driver's side.
In order for the outside rearview mirror assemblies 1 of the automobile to allow the driver to see the entire road portion defined by the regulations, they are provided with a convex spherical mirror 2 having a radius of curvature of the order of 120 to 135 cm.
N-\Melbourne\Cases\Patent\7100O-71999\P71625.AU\Specis\P71625.AU I Specidoc 28/02/07 They are also fastened to the automobile so that the Sdistance dl between the centre of their mirror and the middle of the segment connecting the driver's eyes, as 00 C- 5 projected on the longitudinal axis of the automobile, is of the order of 20 to 40 cm.
00
\O
00 As regards the distance d2, measured vertically, between the centre of their mirror and the middle of C 1 0 the segment connecting the driver's eyes, this is Spreferably of the order of 0 to 40 cm.
It should be noted here that by applying the arrangements above it is possible to eliminate the blind spot in current outside rearview mirrors and consequently improve the road safety conditions.
It is also desirable for the outside rearview mirror assemblies to form projections on the automobile that are less than 10 cm so as not to have to be subjected to the pendulum test.
For this reason, their mirrors generally have a radius of curvature of the order of 130 to 135 cm when they are made of glass and of the order of 120 to 125 cm when they are made of plastic.
Figures 4 and 5 each show a front door located on the driver's side and comprising a metal triangle 3 to which the base 4 of a rearview mirror assembly is fastened, allowing the road portion as required by the regulations to be seen.
The base 4 of the rearview mirror assembly visible in Figure 4 is fastened to the lower part of the triangle 3, whereas that of the rearview mirror assembly visible in Figure 5 is fastened to the upper part of the triangle.
Ni\Melbourne\Caes\Patent\71000-71999\P71625.AU\Specis\P71625.AU GH Specidoc 28/02/07 8 The front door located on the passenger's side also has Sa metal triangle, its outside rearview mirror assembly being fastened to the latter in a position symmetrical, 00 C- 5 with respect to the longitudinal mid-plane of the automobile, with that of the rearview mirror assembly 00 located on the driver's side.
\O
IND
00 The front doors of the automobile may include a C- 10 transparent quarter pane, for example made of glass or plastic. It is desirable in this case for the base of C-i the outside rearview mirror assemblies also to be transparent.
Moreover, the outside rearview mirror assemblies fastened to the front doors may in certain cases include a transparent base acting as quarter pane.
It follows from the foregoing that the present invention allows the field of vision in the mirror of outside rearview mirror assemblies to be substantially increased, without them being oversized and having the drawbacks of conventional rearview mirror assemblies that project from vehicles by more than 10 cm.
In the claims which follow and in the preceding description of the invention, except where the context requires otherwise due to express language or necessary implication, the word "comprise" or variations such as "comprises" or "comprising" is used in an inclusive sense, i.e. to specify the presence of the stated features but not to preclude the presence or addition of further features in various embodiments of the invention.
