Definitions

• the invention relates to an internal reinforcement of a motor vehicle spar.
• a known reinforcement of this type indicated by 1 in FIG. 1, has a cross-section whose dimensions increase in the direction of the rear end 2 of the reinforcement 1 to define a base 3 serving to support a frame upright 4d. a rear side door of the vehicle.
• vehicle base such as a rolling base which comprises for example the chassis, the sleepers or the wheel wells of the vehicle, common to all vehicles in the same range with different silhouettes, such as convertibles, sedans, or minivans.
• vehicle base such as a rolling base which comprises for example the chassis, the sleepers or the wheel wells of the vehicle, common to all vehicles in the same range with different silhouettes, such as convertibles, sedans, or minivans.
• the concept of "rolling base” thus makes it possible to reduce the costs, the assembly times of these vehicles and to use the industrial means making it possible for the different vehicle versions resulting from commercial evolutions.
• the aforementioned reinforcement is not integrable within a “rolling base” because its dimensions and shape change from one vehicle silhouette to another and thus requires for its manufacture special cutting and stamping processes the sheet metal sheet constituting it for each developed vehicle silhouette.
• the invention aims to overcome this disadvantage.
• the invention relates to an internal reinforcement of a motor vehicle spar, having a generally elongate shape and a cross section whose dimensions increase towards one of the ends of the reinforcement to define a support base for a frame amount of a side door of the vehicle.
• the reinforcement comprises a main section and a lining attached to one end of the profile to form with this end the base of the reinforcement, this liner having a larger cross-sectional area than the cross section of the reinforcing section and a rear side extending in the extension of the rear edge of the profile.
• the rear edge of the profile is substantially vertical.
• the lining comprises a portion fixed by welding transversely relative to the profile.
• the fastening portion of the liner extends over the entire height of the profile.
• the profile has a cross section of generally constant shape.
• the invention also relates to the rolling base comprising the profile of the reinforcement above.
• the invention also relates to a motor vehicle comprising the aforementioned rolling base, wherein the lining is interposed between the section of the rolling base and the frame amount and fixed in this position so as to form the reinforcement of the vehicle.
• FIG. 3 is a view similar to FIG. 1 with the reinforcement of FIG.
• the internal reinforcement 6 of spar shown in Figure 2 serves to stiffen the vehicle structure in case of side impact suffered by the latter.
• this reinforcement 6 is fixed to a lower part of the vehicle body located under the front and rear side openings 7, 8 of this bodywork intended to be closed by the corresponding lateral doors of the vehicle and between two passages. lateral wheels of the vehicle.
• This reinforcement 6 thus comprises, when the vehicle in which it is integrated includes for example four side doors, a central portion 9 to be located in line with the central lateral upright 11 of the vehicle, with respect to which the rear door of the vehicle is articulated, and a rear end 12 coinciding with the rear upright 13 of the vehicle, against which said door bears when it closes the rear opening 8. More specifically, this reinforcement 6 comprises an elongate portion 14 which constitutes a lateral beam in the vehicle attached to the chassis of this vehicle, and a base 16 defined by the rear end 12 of the reinforcement 6. This base 16 has a cross section whose vertical dimensions increase towards the free rear edge 17 of the reinforcement and thus comprises a substantially constant lower edge 18 and an upper edge 19 diverging relative to the lower edge 18.
• the base 16 further comprises a portion receiving 21 of the rear upright 13 of the vehicle along its diverging upper edge 19 and which is of complementary shape of the foot 22 of the rear pillar 13.
• the reinforcement 6 comprises a main section 23 and a trim 24 attached to the rear end 26 of the section 23 and which has a cross section greater than that of this end 26 of section. More precisely, as can be seen in FIG. 2, the profile 23 forms the stiffening beam 14 and thus has a generally elongate shape and defines the free rear edge 17 of the reinforcement 6 as well as its rectilinear lower and upper edges 18, 29. the unique stiffening function of this profile 23, it should be noted that its shape varies little or not in the same range of vehicles.
• the profile 23 of the reinforcement of the invention 6 defines a standard part, that is to say, common to different types of vehicles (sedans, minivans, cabriolets) of the same range.
• the lining 24 comprises a fixed portion 24a for example by electrical welding over the entire width of the inner wall 27 of the rear end 26 of the section 23.
• This fixing portion 24a advantageously has a shape complementary to the rear end 26 of the section 23 and is extended by a portion of the lining forming a fin projecting above of the profile, for example a wing of substantially triangular shape 24b, whose base 28 coincides with the upper edge 29 of the profile 23, a rear side 31 of which extends in the extension of the vertical rear edge of the profile 23 which constitutes the free rear edge 17 of the reinforcement 6, and a support side 32 extends from an upper end 33 of the rear side 31 to the upper edge 29 of the profile 23.
• the seal 24 covers, over substantially its entire length, the end corresponding profile 23 so as to ensure good bonding of the two parts.
• This support side 32 further defines a concave curvilinear edge constituting the diverging upper edge 19 of the base 16, and a substantially rectilinear edge 34 connecting the end of the curvilinear edge 19 opposite the profile 23 at the end of the side. rear 31 of the fin 24b of the seal 24.
• the liner 24 defines a small part, attached to the end 26 of the profile 23 and whose shape can be adapted according to the chosen silhouette of the vehicle.
• the standard section 23 of the reinforcement 6 can be integrated within a "vehicle base” such as a so-called rolling base, that is to say which comprises, for example, sleepers, the floor, the wheel wells , the mudguards, the outer spars and the chassis of the vehicle and which will be identical for different vehicle silhouettes.

• Only the lining 24 of the reinforcement 6 will have to be modified according to the chosen silhouette of the vehicle, that is to say, mainly depending on the shape of the doors and the rear side uprights defined for a particular style of the vehicle.
• the invention as described above brings various advantages among which: the possibility of increasing the number of elements of the vehicle that can integrate a "vehicle base" and can thus be manufactured on a large scale for different ranges of vehicle, the possibility to be able to vary the silhouettes of the vehicles of the different ranges, by adapting the shape of the lining to the doors and rear side posts of the vehicle, reducing costs and manufacturing time, and reducing the number of tools needed to make vehicles with different silhouettes.
