Abstract

THE PRESENT INVENTION CONCERNS A VEHICLE IN PARTICULAR PASSENGER CAR, EQUIPPED WITH A FRONT HOOD, A WINDSCREEN, A FLAG TO WHICH FOLLOWS A REAR PART, AS WELL AS DEVICES FOR THE EVACUATION OF SLUDGE WATER AND RAINWATER. THIS VEHICLE IS CHARACTERIZED BY THE FACT THAT ON EACH SIDE OF THE MEDIAN LONGITUDINAL PLANE OF THE VEHICLE, WATER GUIDING CHANNELS (1 TO 5) CONTINUOUS FROM THE FRONT TO THE REAR OF THE VEHICLE ARE PROVIDED. APPLICATION IN PARTICULAR TO PASSENGER CARS.

Description

The invention relates to a vehicle, in particular

  tying a passenger car, equipped with a front hood, a windshield, a pavilion that is followed by a

  rear section, as well as devices for evacuation

  muddy water and rainwater. On most passenger cars, are used for water collection and evacuation

  muddy and rain water that gutters disperse

  placed in the vicinity of the edge of the pavilion, supplemented by separate water catching rods fixed in the area of the windscreen pillars. In large areas of the body of a vehicle, a rationally designed water guidance system is completely lacking; the consequences are a heavy fouling of the vehicle, including ice surfaces, which have an important role for the

driving safety.

  The object of the invention is to avoid these drawbacks

  and to give a vehicle body a conformation such that its fouling is reduced to a minimum, even when the weather conditions are unfavorable. On a vehicle, in particular a passenger car, of the type described at the beginning, the invention solves

  this problem by providing for both sides of the longitudinal plane.

  dinal median vehicle water guiding channels

  continuous from the front to the back of it.

  The invention also proposes to give these water guiding channels an optimal structure in

  the different sectors of the vehicle body.

  This is achieved by the invention, in the area of the joint separating a front cover of an adjacent wing,

  providing between the wing and the hood an elastic seal

  deformable by the closing hood,

  at least a portion of a water guiding channel.

  Thanks to such a conformation, not only is a favorable water guidance obtained, but the area of the seal between hood and wing, particularly dangerous (because rigid) in a collision with the driver of a

  two-wheelers or a pedestrian, is significantly neutralized.

  It is advantageous that the seal has a void space, open upwards, constituting the channel of

water guidance.

  To obtain a better deformability of the joint area in the event of an accident, the invention provides for the seal to be subjected to the pressure of a flange of the cover projecting laterally and that when the hood is closed, there is a certain vertical distance between the

  Hood and adjacent parts of the wing.

  Another point which is problematic with the systems

  known water guiding systems concerns the amounts of

  windshield of the vehicle. To obtain a coefficient

  favorable conditions, that is to say one of the conditions of a reduced consumption of fuel, solutions comprising the assembly of separate rods were

  tried, most often without giving satisfaction.

  Therefore, the invention provides that the

  a water guide is an imprint

  hollow in the windshield pillar.

  In terms of aerodynamic qualities, it is advantageous for the lateral marginal sector of the windshield to have a stronger curvature in the direction of the windshield pillar than the remaining sector or to have a windscreen.

recess.

  The same effect can be obtained by providing that the lateral marginal sector of the windshield is bent and connected to a rod also bent constituting the

  side windshield attachment area.

  The water guide channel may be partially covered by a flange of the windshield pillar,

  a frame profile being mounted on the flange.

  Taken as a whole, the water guidance system according to the invention must be structured in such a way that neither the parts of the windscreen or their attachment system, nor the parts of the windscreen pillar and the duct water guidance do not protrude from the wraparound line of the vehicle. The usual rods for the evacuation of rainwater in the zone of the edge of the pavilion generally disturb the flow of the air when the vehicle is running and constitute during

  accidents from additional sources of danger.

  The invention provides, for this purpose, a water guiding system such that additionally to a main flow channel preferably consisting of a hollow recess in the pavilion plate, is disposed on each side of the vehicle a channel d residual water passing over the doors and covered by them when

they are closed.

  Until now, we neglected to evacuate the water

  coming from the flag in the area of the rear window.

  To ensure this function, the invention provides that in the zone imparted to an ice, are arranged channels

  directed water guidance from top to bottom.

  The peculiarities concerning the guiding

  described in the following section. The water guiding channels are formed in the

ice cream.

  In the case of multi-layer ice, the water-guiding channels are formed only in one or more inner layers of the ice

  and are covered by an outer layer.

4 2484342

  The upper inlet opening of the water guide channels is covered by a strainer or by a

similar element.

  The water-guiding channels are constituted by gutter-shaped section rods mounted

on the ice.

  In the case of a multi-layered ice-cream, in the vicinity of the water-guiding channels, at least one outer layer of the ice has

  interruption and, in the space marking this interrup-

  tion, is mounted a sectional rod shaped gutter. The ice is divided in two in the zone-des

  water guiding channels, and a portion of the ice

  a marginal marginal sector while the other part of the ice is mounted on the recess part and at a certain distance from the recess

well said.

  The ice is divided in two in the vicinity of the water guiding channels and the two parts are fixed in particular by gluing, to an amount or a piece

  similar, a space being reserved between them.

  In the vicinity of the side edges of the windows, there is provided an additional water guide channel constituted

by a vehicle amount.

  The object of the invention is explained more in

  detail, in the following, with the help of examples of

  illustrated in the accompanying figures. These are

front doors.

  - Figure 6, a section of the vehicle roof frame, - Figures 7 to 12, horizontal sections of

  rear windows of different structures.

  In Figure 1, is shown the general layout of the water guiding channels. These channels are marked 1 in the area of the front cover, 2 in the area of the windscreen pillars, 3 in the area of the roof 4 in the area

  of the rear window and 5 in that of the joints of the

back loop.

  FIG. 2 shows an embodiment of the water-guiding channel 1 in the zone of the joint separating the cover 6 from an adjacent wing 7. An elastically-deformable seal 9 supporting the flange 8 of the cover 6 limits by one of its walls the water guiding channel 1, furthermore formed by an imprint

  recessed in the wing 7. Thanks to such a con

  representation of the joint area, the hood 6 can, at this location, during a collision with a pedestrian for example,

  tural construction between hood 6 and wing 7. Other expected benefits: some sound insulation of the engine space and protection of this space against

  fouling at water penetrations from the top.

  In Figure 3, this area has received another conformation

  tion. A seal 10 is provided which has an upwardly open empty space which in itself constitutes the water guiding channel 1. The covering of the hood 6 and of the wing 7 also has the advantage of being sensitive.

  On the rear edge of the hood 6, each channel

  water guide 1 can communicate in a non-repre-

  flushed with a water drain that extends to the front door seal; the water of the windshields presenting for aerodynamic reasons an accentuated profile can thus be conducted to an evacuation hole in the area of the front door seal.

  Figures 4 and 5 show examples of

  production of water guiding channels 2 in the area of the windshield pillars 11. The windshield channels 2 are essentially constituted here by fingerprints

  recessed in the windscreen pillars. 11. On the

  embodiment shown in FIG. 4, the windshield

  water channel 2 being located lower, the evacuation

  the water towards the pavilion is still done correctly. Connected to the windscreen pillars 11 is also provided laterally a residual water channel 14 here constituted by a door seal 15

having received an appropriate form.

  On the execution example shown on the

  5, the windshield 16 is bent in its zone mar-

  ginale and connected to a rod 17 also bent (aluminum for example), rod constituting the lateral attachment area of the windshield 16. On this

  shape, the water guiding channel 2 is covered by

  Tensely by a flange 18 of the amount of windshield 11 on which is mounted a cover profile 19. In Figures 4 and 5, lines in fine line show that the

  driver's field is only slightly reduced by the

  windshield 11, of a relatively

  pick. Figure 6 shows a section in a side area of the roof of a passenger car. The water guiding channel 3 is here constituted by a hollow recess in the sheet metal 20 of the pavilion. Is additionally provided a residual water channel 22 disposed in the area above the doors 21, which channel, when the doors 21 are closed, is covered by them, so that does not affect the presentation of the car and does not act adversely on the coefficient

aerodynamics of the vehicle.

  Figures 7 to 12 relate to guiding the water in the vicinity of the rear window of a vehicle; note however that a water guidance of this form

  could be provided near the windshields.

  In the embodiment of FIG. 7, the rear window 23 has two parts 23a, 23b, the separation being situated in the zone of the water guide channel 4. The two parts 23a, 23b of the ice 23 are fixed by gluing to a post 24 and the space between them constitutes the water guiding channel 4. An additional water guiding channel 25 is here formed by a recessed impression made in a post

back 26.

  In the embodiment of FIG. 6, the water-guiding channel 4 is formed in the ice-cream 27, which can be manufactured, for example, in PC with

silicate coating.

  Figure 9 shows an example of execution

  the same, however, a 28

  carrying two layers 28a, 28b, the water guide channel 4 being formed in the inner layer 28a. The

  material used may be that used for the manufacture of

  cation of ice 27, while the outer layer

  smooth arm 28b is preferably constituted by

2484342-

  glass. The upper inlet of the water guide channels 4 may be covered by a strainer or

  by a similar element not shown.

  To form the water guiding channels 4, it is also possible to provide separate elements, as shown in FIGS. 10 and 11. FIG. 10 shows an ice-cream 29 consisting of a single layer of glass, on which a rod 30 having in section the form of a gutter is mounted, rod which constitutes the channel

  two layers 31a, 31b, the outer layer

  31 b with an interruption in which a

  watch 32 having in section the form of a gutter is mounted, this rod constituting the guide channel

of water 4.

  As a final example of the execution of the invention

  FIG. 12 shows an ice 33 having two portions 33a and 33b, the portion 33a having ice 33 having a marginal zone in recess and the other portion 33b being mounted on this jogging zone at a certain distance. of the step itself

  34; a water guiding channel 4 is thus constituted.

  The water guide channels 5 of the section

  can be formed in the image of the water guide channels 1 of the front part of the vehicle. In order to prevent the muddy water being evacuated from being subjected to an evacuation vortex effect on the rear of the vehicle in motion and not being deposited again on the bodywork, it is advantageous to provide at the end of water guide channels of the outlets

  opening below the bumper.

  For all channels, a significant reduction

  noise due to the flow of air and an improvement in

  Cw factor are obtained by embedding the gutters in the direction of the vehicle axis, far from the

  critical marginal areas. Only through this

  position that it is possible to maintain the wings
