    [0001] The invention relates to the field of motor vehicles. More particularly, the invention relates to the ability of a motor vehicle to absorb energy in the event of a side impact of the vehicle. More particularly, the invention relates to a side door of a motor vehicle and a corresponding motor vehicle, preferably to four side doors. A side door of a motor vehicle generally comprises on its rear flank a lock for locking the door and a manual control handle of the lock for opening the door The control handle is generally located in front of the lock and at the height of the hand, the door further comprising a control cable connecting the control with the lock through a cable passage. A door is, in addition, generally consists of an outer wall and a lining or inner wall; the lining forming the side flanks of the door, the lock being supported on the rear side flank, the door hinges being located on the opposite front side. On particular models of motor vehicle, the arrangement of the lock can be reversed and be fixed on the front flank of the door liner. In the event of a side impact of the motor vehicle, the outer wall of the door deforms and may cause the deformation of the cable passage for the control of the lock. This deformation can generate traction on the cable and thus unlock the lock of the door. However, the current requirements for the production of a motor vehicle and their approval require that the side door must not open in the event of a side impact so as not to increase the damage to the occupants of the vehicle, pedestrians or passengers. other vehicles.
    [0002] Patent document FR 2 904 792 A1 discloses a vehicle side door comprising a stiffener applied on the inner face of the outer wall of the door and extending vertically in the door. The stiffener is a stamped portion comprising a horizontal portion along the upper edge of the door at the window pane and a lower portion extending vertically at half height of the door, the stamp forming a Y. The teaching is interesting in that the stiffener provides significant stiffness able to stiffen the area of the opening on which it is located. The solution of this teaching is, however, applicable only for an area located longitudinally at a central position in the door, away from the mounting area of the interlocking lock opening control handle at the outer wall of the door. door. Patent document EP 1 405 746 B1 discloses a door configuration in which the vehicle has no intermediate amount between the front and rear doors. In this configuration, the rear door is substantially shorter than the front door. The front and rear doors each comprise an S-shaped stiffener extending vertically along the rear or front side, respectively, more precisely a first branch of the S being fixed to the bottom of the liner, the body of the S along the side of the door. An outer wall is assembled to the liner. The front door comprises, in addition, a second stiffener, preferably a third stiffener, extending in the longitudinal direction of the vehicle and along the outer wall. The longitudinal stiffener or stiffeners are fixed to the rear flank of the door liner via the second branch of the S-shaped stiffener. The teaching of this document is interesting in that the S-shaped stiffener is able to stiffen the zones of the door. locking locks, corresponding to the intermediate post absent. The longitudinal stiffener or stiffeners are arranged in the front doors and are intended to absorb the lateral impact energy by resting on the vertical S-shaped stiffeners. Patent document FR 2 937 288 B1 discloses a rear door of a motor vehicle comprising an inner wall joined to an outer wall. The inner wall comprises a rear side flank, the door comprising a lock bearing against said sidewall. The door further comprises a longitudinal stiffener extending along the inner face of the outer wall. The stiffener extends in a slightly inclined direction relative to the horizontal, a first end being fixed to the side opposite the lock, the one comprising the door hinges. The second end of the stiffener comprises a weakening zone adapted to absorb by deformation of the side impact energy. This second end is set slightly back from the rear flank at the bottom of the inner wall. This teaching is interesting in that the deformation of the door is concentrated at the level of the weakening zone just near the flank carrying the lock, which in this case limits the deformation of said flank. The area of reduction of the deformation of the door is however limited. The object of the invention is to propose a solution that overcomes at least one drawback of the state of the art, in particular of the state of the art mentioned above. More particularly, the invention aims to provide a simple concept solution to limit the inadvertent opening of the door during a side impact. More particularly, the invention aims to limit the deformation of the door at the control cable connecting the control handle and the lock.

The invention also relates to a motor vehicle comprising one or more side doors, remarkable in that the or at least one of the doors is in accordance with the invention. The measurements of the invention are interesting in that the door is able to absorb the energy of a lateral impact of the vehicle so as to limit its deformation at the areas where the control, the control cable and the lock are located. closing the door. Indeed, the stiffener located in front of said zones creates a deformation filter capable of directing the deformation of the outer wall below and / or above said zones. In addition, the reinforcement of the door is simple concept and is economical to achieve. Other features and advantages of the present invention will be better understood from the description and drawings in which: FIG. 1 is a perspective view of a motor vehicle door according to the invention; - Figure 2 is a view of the door of Figure 1 after a side impact of the vehicle against said door; - Figure 3 is a view of the door of Figure 2 at the opening control; - Figure 4 is a cross section of the stiffener of the door of Figures 2 and 3; Figure 1 is a perspective view of a door 2 of a motor vehicle according to the invention. The door 2 comprises a rear wall 4, commonly called the door liner, and an outer wall joined to the liner 4. The outer wall is however not shown so as to display the structure of the door 2 between the two walls. The door 2 is in this case a rear door which comprises an upper right portion 6 and a lower portion 8 which is curved to fit a vehicle rear wheel well; the curvature of the lower portion 8 is at the lower portion of the corresponding lateral edge 11 of the door 2. The lining 4 forms lateral flanks 12 and 12 ': the rear lateral flank 12 (on the right in the image) comprising a mounting zone 14 of a lock 16 for closing the door 2; the front lateral flank 12 '(left on the image) receives the fixing hinges (not shown) of the door 2 to the vehicle. The door also comprises a control handle 18 which is located in a mounting zone 20 of the outer wall in front of the lock 16; "Ahead" means in relation to the forward direction of the vehicle indicated on the picture by an arrow. This mounting zone 20 is shown in the image so as to locate the position of the handle 18 on the door 2. The latter comprises, finally a control cable 22 connecting the handle 18 to the lock 16. The door 2 comprises a stiffener 24 extending to the front of the mounting zone 20 of the control handle 18. The stiffener 24 is presented alone enlarged to the right of the main image of the door 2. The stiffener 24 is oriented so inclined relative to the vertical direction and at an angle of between 100 and 25 °, it is fixed at its lower end 26 to the curved lower portion 8 of the door 2, and at its upper end 26 ' at the upper portion 6 right of the door. More specifically, the lower end 26 is fixed to the lining 4 of the door 2 and the upper end 26 'is fixed to the edge 7 of the outer wall (not shown) in this case via an intermediate strip extending into the longitudinal direction of the vehicle. In the section of the door, the stiffener 24 extends along the inner face of the outer wall. Regarding the positioning of the stiffener 24 in the longitudinal direction of the vehicle, it is at a distance of less than 15 cm, preferably 10 cm, from the mounting area 20 of the control handle 18. It may be noted that the stiffener 24 comprises a central portion 30 of profiled cross section. The stiffener is, in addition, in contact at its central portion 30 with the inner face of the outer wall; it can be attached, especially by gluing, to the inner face of the outer wall. It can be observed that the mounting area 20 of the control handle 18 as well as the control cable 22 are mainly at the height of this central portion 30 of the stiffener 24. By observing the stiffener 24 on the enlarged portion of the image, sees that it is formed in a sheet metal strip of profiled cross-section. The stiffener 24 comprises at least one weakening zone, in this case it comprises two weakening zones 32 and 32 'opposite the central zone 30 of profiled section and which is devoid of weakening zone. The central portion 30 may have an E-section section. The cross-section of the weakening zones 32 and 32 'is generally straight; their longitudinal section may be U-shaped. These weakening zones 32 and 32 'are located at a distance from the middle of the stiffener which is greater than a quarter of the total length "L" of the stiffener, they are also located by ratio to the ends 26 and 26 'of the stiffener to less than 35% of the length "L" of the stiffener 24; they can extend in the stiffener over a distance "D" and "D" between 10mm and 70mm, preferably between 20mm and 40mm. These weakening zones 32 and 32 'have a quadratic moment in bending less than 50%, preferably 30%, of the mean quadratic moment of the stiffener 24 outside the weakening zones. This measure of the invention is interesting for giving the stiffener 24 the ability to absorb the energy of a lateral shock by the deformation of the stiffener at the weakening zones. The stiffener 24 is a folded sheet or stamped at the two weakening areas 32 and 32 ', the profiled sections of the stiffener being preferably made by stamping. The stiffener may be of steel with a yield strength of between 150 MPa and 400 MPa.
    [0008] Figure 2 is a view of the door 2 according to the invention after a side impact of the vehicle against said door. It is possible to observe two main deformations 34 and 34 'of the outer wall 5 of the door 2, said deformations extending mainly in the longitudinal direction of the vehicle below and above the passage zone of the control cable 22 (shown in FIG. dashed) opening the lock. Figure 3 is a view similar to the view of Figure 2, but the outer wall is not shown. The weakening zones 32 and 32 'of the stiffener 24 have absorbed a portion of the side impact energy of the vehicle. The central portion 30 of the stiffener 24 in contact with or attached to the outer wall of the door is not deformed and effectively protects the mounting area 20 of the opening control 18 of the door 2 and the cable of the door. opening 22.
    [0009] Figure 4 is a section of the stiffener 24 after a side impact of the vehicle against the door according to the invention. An example of a deformation profile of the stiffener can be seen here, the weakening zones 32 and 32 'being deformed, the central portion 30 of the stiffener being free of deformation.
