Definitions

• the present invention concerns a chassis element for a motor vehicle.
• EP-A-0 749 890 describes a self- supporting side of a motor vehicle comprising an inner part and an outer part, between which is interposed an annular chassis element which defines the front door space, and which is manufactured by pressing.
• the object of the present invention is a chassis element for a motor vehicle, characterised in that it is manufactured from at least one pressed or profiled bar which is then subject to bending.
• the essence of the present invention is therefore the use of bending techniques - which are significantly simpler and more economical than pressing techniques - to obtain the final desired shape for the chassis element being manufactured.
• pressing techniques can still be used within the ambit of the present invention in order to manufacture the bar that is subsequently subjected to the bending operations.
• pressing is, in fact, used to obtain pieces of simple shape, when the disadvantages described above do not arise.
• the final complex shape of the chassis element is obtained by bending the bar in all necessary dimensions, specifically in three dimensions, so as to be able to form the necessary undercuts and reduce the quantity of waste produced during working to a minimum.
• the chassis element of the invention may have a constant or variable section and may be made from any metal commonly used in the construction of motor vehicles, in particular, high strength steel which, although difficult to work by pressing, enables consistent reductions in weight to be obtained for the same performance.
• Figure 1 is an exploded perspective view of the side of a motor vehicle including a chassis element according to the invention
• Figure 2 is a view of the side of Figure 1 from a difference perspective
• Figures 3 and 4 are exploded perspective views of sides of motor vehicles including chassis elements manufactured according to respective further embodiments of the present invention.
• the side of a saloon type motor vehicle includes ( Figures 1 and 2) a chassis element 10 having first, second and third arms 12, 14, 16 intended to surround respectively the front, top and rear of the door space.
• the element 10 is C-shape in section and is obtained by bending a profiled bar in three dimensions .
• the element 10 Conventional components of the motor vehicle chassis and body are attached to the element 10, such as a cill 18, a central pillar 20, front and rear lock supports 22, 24, a cover 26 for the upper arm 14, a lower cross-beam 28 for the windscreen and front and rear roof elements 30, 32.
• elements 34, 36 are also associated with the element 10, which elements are annular and open along a generatrix 38, and define the perimeter of the door space at the front and rear, respectively.
• the elements 34, 36 are also obtained by bending a profiled bar in three dimensions.
• FIG. 3 illustrates a variant embodiment of the invention.
• the parts that are the same as or equivalent to those illustrated in the " preceding drawings are given the same reference numerals and are not further described.
• the element 10 has first and second arms 12, 14 only, intended to surround the front and top, respectively, of the door space.
• the rear of the door space is bordered by a rear pillar 40 separate from the element 10. 4
• FIG. 4 illustrates a further embodiment of the invention.
• the parts that are the same as or equivalent to those illustrated in the preceding drawings are given the same reference numerals and are not described further.
• the second arm 14 of the element 10 extends rearwardly beyond the end portion of the door space and a third arm 16b, the length of which is less than the height of the door space, projects transversely from the rear end thereof.
• This configuration is adapted to a station wagon type of motor vehicle.
