Abstract

Lower berry crossbar consisting of a single wall.The lower berry beam (30) can be made in one piece with an apron. It may comprise a hollow body delimited between a lower end of the lower berry rail and an apron (18).

Description

LOWER BAY TRAVERSE CONSISTING OF A SINGLE WALL

  TECHNICAL FIELD The invention relates to a lower crossbar bay. Motor vehicles have a structure under the windshield which serves to support the lower end of the windshield. This structure is commonly called lower bay transom. The currently known lower belly sleepers meet specifications but are complex in their number of pieces and the design of these pieces. The present invention specifically relates to a lower berry beam that overcomes these disadvantages. These objects are achieved in accordance with the invention in that the lower berry beam consists of a single wall. Thanks to this characteristic, the number of pieces is reduced to a minimum. In addition, the design of the cross is simplified. In a particular embodiment, the lower berry beam comprises a hollow body delimited between a lower end of the lower berry rail and an apron. In another particular embodiment, the lower berry beam is made in one piece with an apron.

  This lower berry beam may comprise a hollow body delimited between a fold of the piece forming the apron and a closure plate. Advantageously, the crosspiece comprises a double wall formed by laser splicing. The lower berry beam has a generally flat shape terminated by a bracket on which rests the lower end of the windshield.

  Other features and advantages of the present invention will become apparent upon reading the following description of exemplary embodiments given by way of illustration with reference to the appended figures. In these figures: - Figure 1 is a schematic sectional view of a first embodiment of a lower crossbar bay of the prior art; - Figure 2 is a schematic sectional view of another embodiment of a lower crossbar bay of the prior art; - Figure 3 is a schematic sectional view of a first embodiment of the invention; - Figure 4 is a schematic sectional view of a second embodiment of the invention; - Figure 5 is a schematic sectional view of a third embodiment of the invention; FIG. 6 is a diagrammatic sectional view of a fourth embodiment of the invention.

  FIG. 1 is a diagrammatic cross-sectional view of a lower rack cross-section according to a first embodiment of the prior art. As can be seen, the lower berry beam comprises a hollow body consisting of three parts 10, 12 and 14 joined together by welding spots. A heating partition 16 is further connected and welded to the lower end of the piece 14. An apron 18 is also welded to the lower end of the piece 14. In this embodiment the sub-bay area is shaped particularly complex. It also comprises a large number of parts. FIG. 2 shows another embodiment of a lower rack crossmember. In this example, the lower rack crosspiece consists of an upper part 19 and a lower part 20. The part 19 and the part 20 are connected to each other by welding spots 22. In addition, an apron 18 is welded at 24 to the lower part of the piece 20. In this embodiment, the number of pieces is smaller. However, these pieces have forms of great complexity. FIG. 3 shows a first embodiment of the invention. In this embodiment, the lower crosspiece 30 has a particularly simple shape since it consists of a generally flat wall 32 and a bracket 34 perpendicular to the wall 32. the lower part of the windshield 36 comes rest on the bracket 34 through a windshield seal 38. The lower bay cross member 30 is connected to an apron 18 and is fixed thereto by welding points. FIG. 4 shows a second embodiment of a lower rack cross member according to the invention. In this embodiment, the lower bay crosspiece 30 has a wall 32 of generally flat shape. At the lower end of this flat wall are formed two folds 40. The apron 18 has a docking tab 42 which is applied on the rectilinear portion 32 of the lower crosspiece of bay 30. The apron 18 defines with the part lower part of the bottom crossbar a box 44. The box 44 forms a hollow body between the cups of the front wheel shock absorbers of the vehicle. FIG. 5 shows a third embodiment of a lower rack cross member according to the invention. This embodiment is characterized in that the lower cross member 30 is formed in one piece with the apron. The number of pieces is therefore particularly reduced since it is limited to one piece. The lower bay rail is made by laser splicing. In other words, two or more sidewalls are placed one against the other and welded together by laser welding and then stamped simultaneously in a single operation in the same tool. The number of stamping operations is thus reduced to one.

  FIG. 6 shows a fourth embodiment of a lower rack beam according to the present invention. In this embodiment, as in that of Figure 5, the lower cross member 30 and the deck 18 are formed in one piece. Advantageously, this single piece can be obtained by laser splicing, that is to say, as explained, consisting of two plates of laser-welded metal sheets and stamped in the same tool. The lower berry beam has two folds 40 so as to define a hollow body 44 which is closed by a closure plate 46. A hollow body is thus defined between the cups of the front wheel shock absorbers of the vehicle.
