Description

Panoramic bay window

  The present invention relates to a bay window, for motor vehicles, which allows the driver to have a panoramic view towards the front of a vehicle.

  Motor vehicles include a passenger compartment which is delimited at the top by a bay window surmounted by a flag. The bay window and the roof are supported by uprights, and generally two uprights at the front of the vehicle, inclined towards the rear and between which a windshield extends. The latter has side edges mounted in support and glued for example against the uprights.

  The amounts are generally made in a solid profile, and they are covered in the passenger compartment by a relatively large lining allowing both to hide the amount and also to constitute a wall capable of damping a shock and particularly the head of a driver. A disadvantage lies in the width of the amount equipped with the trim lining, which limits the visibility of said driver in normal driving situation.

  The amounts are sometimes made of hollow profiles, from two open sections welded together facing each other to form a tubular element which then extends along a section of a bearing portion receiving the side edge windshield, to a free portion located in the passenger compartment and that, to reduce the width of the amount. However, such amounts are expensive to make, and also they are very unattractive.

  Reference can be made in particular to document FR 2 593 458, which describes a motor vehicle equipped with such a type of amount.

  A problem that arises then and that aims to solve the present invention is to provide a bay window, whose amounts not only offer great visibility to the driver, but also, are inexpensive to produce.

  To achieve this object, the present invention provides a bay window for a motor vehicle, said motor vehicle comprising a passenger compartment delimited in part by said bay window, said bay window comprising a windshield and amounts to maintain said windshield, said windshield having side edges mounted to bear against said uprights, each of said uprights having a tubular member having a bearing portion and an opposing free portion, said bearing portion being adapted to receive a lateral edge of said windshield and said free portion projecting in said passenger compartment, said lo tubular element extending, in one section, said bearing portion converging towards said free portion; according to the invention, said tubular element is made in a profile in one piece.

  Thus, a feature of the invention lies in the implementation of a profile made in one piece, so much cheaper, to form the amounts of the bay window. The profile is for example made of aluminum.

  According to a particularly advantageous embodiment of the invention, said bay window further comprises a glazed deflector having another lateral edge, said windshield and glazed deflector being mounted edge to edge, said edges bearing against said portion supporting said tubular member, and said tubular member has an outer flange which protrudes from said bearing portion and between said side edges, said outer flange having a return adapted to cover one of said side edges.

  In this way, the amount makes it possible to maintain both the windshield and the glazed deflector, the lateral edge of one being bearing against the outer flange and engaged between the return and the support portion while the other lateral edge is glued against the bearing portion along the outer flange, which extends between the two side edges.

  According to a preferred embodiment of the invention, said tubular element has a substantially triangular section, having two opposite sides, said opposite sides joining to form said free portion. Thus, the tubular element has in section, an outwardly facing bearing surface which forms the bearing portion, and two opposite sides which from this bearing surface converge towards the inside of the cockpit and in particular in the direction of the driver's seat. In this way, the driver's vision is obscured only by the support portion, which is really useful for holding the windshield and the glazed deflector.

  Of course, the free portion is rounded so as not to hurt the passengers of the vehicle in case of shock. Moreover, the tubular element being hollow by nature, its walls are then deformable, and allow to absorb shocks in case of accident. In addition, the inside of the upright makes it possible to house bundles of cables.

  Advantageously, said tubular element has an inner flange projecting from said support portion and spaced from said outer flange, said flanges forming a groove for receiving an adhesive material, for example in the form of a bead of glue. The groove forming part of the bearing portion and the adhesive is then applied longitudinally in the groove. Then the side edge is applied and held in abutment against the bead of glue.

  According to a particularly advantageous embodiment, said inner wing extends in a direction opposite to said return relative to said outer wing, so as to be able to bond a lateral edge of one side of the outer wing, and to be able to engage the other side edge under the return.

  Preferably, the side edge of said windshield is engaged between said bearing portion and said return. Thus, the tubular element and the windshield are likely to be pre-mounted, and then be assembled with the other elements of the body of the motor vehicle.

  Advantageously, said outer wing has a lug, and it further comprises a seal intended to cover said lateral edges and to snap behind said lug. In this way, the seal is easily adjusted against the two side edges joined, without the need to provide other attachment means.

  Other features and advantages of the invention will appear on reading the following description of particular embodiments of the invention, given by way of indication but not limitation, with reference to the accompanying drawings, in which: FIG. 1 is a schematic cross-sectional view of an element of a bay window according to the invention, according to a first embodiment; and, - Figure 2 is a schematic cross-sectional view, according to a second embodiment.

  Figure 1 shows a bay window portion and in cross-section in a first variant, a tubular element 10, and partially a windshield 12 and a glazed deflector 14. The windshield 12 and the glazed deflector 14, isolate a passenger compartment 16 of a motor vehicle vis-à-vis an outside 18. The windshield 12 has a first side edge 20 and the glazed deflector 14 has a second side edge 22. In addition, the tubular element 10 has a portion 24, an opposite free portion 26 located inside the passenger compartment 16, and two opposite sides 28, 30 which converge towards the opposite free portion 26, surrounding a free space 31, so as not to obscure moreover, the field of vision of a driver installed in the passenger compartment 16.

  Furthermore, the tubular element 10 has an outer flange 32 which protrudes from the bearing portion 24 by dividing it in two, a first portion 34 against which is applied the first lateral edge 20 and a second portion 36 against which the second lateral edge 22 is applied. Moreover, the second part 36 forms a recess with respect to the first part 34.

  As for the outer flange 32, it ends with a return 38 which extends substantially parallel to the first portion 34 of the bearing portion 24, so that the first lateral edge 20 of the windshield 12, can come into engagement between the return 38 and this first part 34. It is for example kept glued.

  In addition, the tubular element 10 comprises an internal flange 40 forming a flange at the end of the second portion 36 opposite to the outer flange 32 in the extension of one of the two opposite sides 30. inner flange 40 and outer flange 32, substantially constitute a groove 42 adapted to receive a bead 44 of sealant or adhesive against which the side edge 22 of the glazed baffle 14 abuts in the extension of the windshield 12. Thus , the second portion 36 in recess allows io to house the bead of glue 44.

  Thus, the tubular element 10 is made in a one-piece profile made of aluminum with its outer and inner wings 32 and 40. In addition, the tubular element is a part of appearance, which has a free portion 26 rounded and non-blunt and that does not require special lining which would then expand the tubular element 10 and reduce the field of vision of the driver.

  Furthermore, the outer flange 32 has a first lug 46 opposite the return 38, oriented towards the second portion 36 and with which, a profile gasket 48 can be held in abutment against the two side edges 20, 22. To do this, the profile gasket 48 has two opposite lips, one 50 applying to the first lateral edge 20, the other 52 applying to the second lateral edge 22, and a projecting rib 54 located between the two and provided with a complementary lug to engage in the first lug 46.

  Referring now to Figure 2, illustrating in a second embodiment, a tubular element equipping a bay window according to the invention.

  The elements playing the same role will carry an identical reference assigned with an apostrophe sign.

  There is thus a tubular element 10 ', a windshield 12' and a glazed deflector 14 '. On the other hand, the essential difference lies in the fact that here, it is a second lateral edge 22 'of the glazed deflector 14' which is engaged with the tubular element 10 'and no longer a first lateral edge 20' of the barrier. breeze 12 '.

  However, the tubular element 10 'always has a bearing portion 24', an opposite free portion 26 ', and two opposite sides 28', 30 'converging towards the opposite free portion 26'.

  The tubular element 10 'also has an outer flange 32' which protrudes from the bearing portion 24 ', always dividing it into two portions 34', 36 '. The first part 34 'is, according to this variant, located opposite to the previous variant, and it is the second side edge 22' of the glazed deflector 14 'which then applies against this first portion 34'. Furthermore, the second portion 36 'also forms a recess relative to the first portion 34' for receiving a bead 42 'of adhesive and applies the first side edge 22' of the windshield 12 '.

  The outer flange 32 ', ends with a return 38' which extends not on the windshield 12 'but on the second side edge 22' of the glazed deflector 14 'to keep it engaged.

  The tubular element 10 'also comprises an internal rim 40' forming a flange, at the end of the second part 36 'opposite to its position according to the preceding variant embodiment, and with respect to the outer flange 32 'in the extension of the other opposite side 28'. Thus, the inner flange 40 'and the outer flange 32', constitute a groove 42 'adapted to receive a bead 44' of glue against which the first side edge 20 'of the windshield 12' bears.

  This tubular element 10 'is also made in a one-piece profile, for example, aluminum with its outer flanges 32' and inner 40 'and a free portion 26' rounded.

  The outer flange 32 'has a first lug 46' opposite the return 38 ', facing the second portion 36' and with which a profile gasket 48 'is held astride the two side edges 20', 22 '. The profile gasket 48 'has two opposite lips, 50', 52 'and a projecting rib 54' located between the two and provided with a complementary lug to engage the first lug 46 '.

  According to this second implementation variant, the glazed deflector 14 'is then pre-assembled with the tubular element 10'.

  Thus, thanks to the tubular elements 10, 10 ', mentioned above, which do not require any particular lining and moreover which extend along an oblong section, in the direction of the field of view of a driver in the driving position, the field of vision precisely is much less obscured, for a rigidity of the maximum amounts.

  Furthermore, thanks to the free space 31, 31 ', of the tubular element 10, 10', a cable tray can be installed.
