Definitions

  • the object of the present invention is a blocking system for blocking the opening of a vehicle door in situations involving lateral impact against said vehicle door.
  • the door opening blocking system object of the present invention is particularly applicable in the field of automotive industry, and more specifically in the field of passive safety devices for a vehicle.
  • the object of the present invention is a vehicle door incorporating the mentioned opening blocking system.
  • Lateral impacts against the side doors of a vehicle may occur both in a situation involving a moving vehicle and in a situation involving a non-moving vehicle. Said impacts cause the deformation of the different structural elements forming the door, leading to their compression. These deformations may cause a structural element of the door to contact and push the cam which accidentally actuates the door unlocking mechanism, causing the undesirable opening of the door.
  • the device comprises a rigid frame with three supporting points with respect to the internal structure of the door.
  • Said supporting points are in the form of lugs or rods.
  • Each of said supporting points comprises a weakened area (an annular flange or rib) allowing the collapse or axial movement of the supporting point, and thereby the movement of the entire frame of the device.
  • the force of the impact may be sufficient to deform the vehicle door, and thereby push the blocking device, which deforms or breaks in the weakened area, causing the device to collapse.
  • the movement or collapse of said blocking device it gets in the way of the provided path of the mechanism of the lock, such that said mechanism cannot complete its travel, the opening of the door thereby being prevented.
  • the variant described in the preceding paragraph has two significant drawbacks. Moreover, it takes up a large volume within the internal structure of the door.
  • the internal structure of the vehicle door usually comprises two sheet metal elements (outer sheet metal and inner sheet metal), an inner plastic lining, an outer lever allowing the door to be actuated by a user from outside the vehicle, a structural support for said lever (which provides rigidity to the lever assembly), and a mechanical transmission element between the lever and the lock (where the lock allows unlocking the movement of the door upon the actuation of the lever).
  • the mechanical transmission element is typically a "Bowden cable" which transmits the movement of the lever directly to the lock.
  • Other elements such as window, window movement mechanism, loudspeakers, actuators, sealing elements, etc. can also be found within the door structure. As can be seen, many elements are found in the internal structure of the door, so introducing a device like the one described in the mentioned document may constitute a design obstacle that is not feasible in many vehicle models.
  • the rigid frame is fixed at three different points and the weakened areas thereof are in correspondence with each of the three fixing points, said device behaves in an ideal manner in those situations involving impact in which the impact is perpendicular to the plane formed by the three fixing or anchoring points, i.e., when the impact is in the same direction of the lugs or rods.
  • the behaviour of the device might not be ideal, where none of the fixing points of the device may end up collapsing. In this case, the device may not be able to block the opening of the door.
  • the device comprises a flexible frame which deforms when the sheet metal of the door deforms, getting in the way of the path of the mechanism for opening the lock of the door, so said mechanism cannot complete its travel, and the opening of the door is therefore blocked.
  • This variant also has the drawback of taking up a large volume within the structure of the door. Moreover, if the reinforcement of the lever breaks into pieces during lateral impact, this variant may not behave in an ideal manner as the device does not get in the way of the path of the door opening mechanism.
  • the present invention relates to an opening blocking system for a vehicle door.
  • the opening blocking system for a vehicle door comprises a lever, pivotable with respect to a reinforcement element of said lever; this lever reinforcement element is the element which allows fixing the lever to the structure of the door and provides rigidity to withstand the forces a user exerts on the lever, among others.
  • the lever comprises an actuation cam, such that an actuation on the lever causes movement of the actuation cam which in turn causes the unlocking of the door.
  • the opening blocking system for a vehicle door comprises a blocking device which in turn comprises fixing means for fixing to the reinforcement element.
  • the blocking device can be moved to prevent the accidental unlocking of the door.
  • the blocking device comprises a first section, a second section, and a break area.
  • the first section is attached to the second section through the break area.
  • the first section comprises a projection extending away from the reinforcement element.
  • the blocking device is configured such that, when the projection receives pressure (pressure exerted by any element on the projection), the break area breaks, releasing a movement of the first section of the blocking device to a blocking position.
  • the blocking device allows free movement of the actuation cam.
  • the first section of the blocking device will be caused to move to the blocking position, hindering the movement of the actuation cam.
  • the break area is configured to break if the pressure on the projection of the blocking device exceeds a specific value.
  • the projection is configured as the first component of the blocking system which receives the pressures of another component of the vehicle door as it compresses during the impact. Arranging the first contact point of the blocking device away from the actuation cam allows anticipating breakage and preventing other components from hindering the movement of the blocking device, preventing the blocking device from performing its function.
  • the break area is a weakened area.
  • the break area can be a narrowing of the first section, and can be obtained with a material cutting process.
  • the fixing means comprise at least one first attachment element for attaching the first section to the reinforcement element of the lever and at least one second attachment element for attaching the second section to the reinforcement element of the lever.
  • the at least one first attachment element is arranged at the end farthest away from the first section with respect to the break area.
  • the at least one second attachment element is arranged at the end farthest away from the second section with respect to the break area.
  • the first section comprises an articulation segment arranged between the at least one first attachment element and the projection.
  • This articulation segment is configured for causing an articulation (which can be a rotational movement or a pivoting movement) of the first section of the device around the articulation segment thereof when the break area breaks.
  • This feature facilitates the dynamics or modus operandi of the blocking device, favouring the occupation of the blocking position by the first section after the break area breaks, guiding the movement of the first section from the standby position to the blocking position. Similarly, the movement being towards other directions is limited, ensuring the proper operation of the blocking device.
  • the articulation segment is a weakened area. This feature simplifies the construction of the blocking device.
  • the articulation segment is arranged in a vertex of the first section (for example, forming an angle of about 90°). This feature favours the articulation, pivoting, or rotational movement of the articulation segment, particularly in the case where the articulation segment is a weakened area.
  • the articulation segment is located close to the at least one first attachment element. This feature also favours the articulation, pivoting, or rotational movement of the articulation segment, particularly in the case where the articulation segment is a weakened area.
  • the projection is located close to the break area. This feature favours the breakage of the break area when there is a specific pressure on the projection, thereby ensuring the proper operation of the opening blocking system object of the present invention.
  • the projection incorporates a contact surface, wherein said contact surface is substantially perpendicular to the actuation path of the actuation cam, with the first section being in the blocking position. In the blocking position, this feature favours achieving a more stable blocking action by the projection with respect to the movement of the actuation cam.
  • the blocking device is made from a plastic material. This feature simplifies the construction of the system, and specifically of the blocking device.
  • the blocking device comprises a substantially longitudinal geometry. This feature favours optimal space saving inside the vehicle door.
  • the present invention also relates to a vehicle door comprising an opening blocking system as described above.
  • the blocking device is arranged between the reinforcement element of the lever and a lock of the vehicle door.
  • the lock will apply pressure on the projection when the elements of the door collapse. Therefore, the projection is prolonged towards a direction contrary to the direction of the reinforcement element of the lever, approaching the lock, so as to anticipate the start of the movement of the blocking device from the standby position thereof to the blocking position thereof.
  • another element of the door structure could be arranged opposite and superimposed on the reinforcement element of the lever, in the area of the actuation cam.
  • the present invention relates to an opening blocking system for a vehicle door.
  • Figure 1 shows the arrangement of the lever (1) and the reinforcement element (2) of the lever (1) of the vehicle door.
  • the lever (1) is attached to the reinforcement element (2) of the lever (1).
  • the reinforcement element (2) is fixed to the structure of the door, for example, to an outer sheet metal of the side door of the vehicle.
  • the present invention relates to an outer lever (1) of the vehicle, which enables a user, located outside the cabin of the vehicle, to open the door.
  • the lock (3) fixed to another structural element of the door, is observed.
  • the lock (3) is suitable for locking and unlocking the vehicle door according to a position of the inner lever or the outer lever (1).
  • the actuation cam (5) of the lock (3) is shown in the reinforcement element (2) of the lever (1).
  • said cam (5) moves, transmitting said actuation, for example by means of a Bowden cable (4), to the lock (3), actuating the mechanism of the lock (3) and thereby causing the opening of the door.
  • the internal structure and elements of the door may deform and compression may occur, such that the reinforcement element (2) of the lever (1) may approach the lock (3) (or vice versa).
  • a pressure may be involuntarily exerted on the actuation cam (5) by the body of the lock (3), or any other internal component of the door, which can cause the movement of the actuation cam (5) and the accidental opening of the vehicle door.
  • Figure 2 shows the blocking device (6) of the system of the invention, located between the reinforcement element (2) of the lever (1) and the lock (3).
  • the blocking device (6) comprises a rigid or semi-rigid body (also referred to as a "protective cover”) with an elongated geometry, preferably made from a plastic material.
  • the body of the device (6) comprises a first section (7) and a second section (8), separated by a break area (9).
  • Said break area (9) is preferably a weakened area (a narrow area or an area with smaller material thickness).
  • the first section (7) of the device comprises a projection (10) and an articulation segment (11).
  • Said articulation segment (11) can be a weakened area or a hinge.
  • the body of the device (6) comprises fixing means (12) for fixing to the reinforcement element (2) of the lever (1) of the vehicle door.
  • said fixing means (12) comprise a first attachment element (13) for attaching the first section (7) to the reinforcement element (2) and a second attachment element (14) for attaching the second section (8) to the reinforcement element (2).
  • the device (6) is caused to break in the break area (9) thereof if this collision, together with the pressure produced by the deformation and/or relative approximation of the reinforcement element (2) of the lever (1) and the lock (3), exceeds a magnitude of pressure greater than a predefined value.
  • the first section (7) of the device (6) bends or is articulated around the articulation segment (11) thereof. In light of the deformation and/or relative approximation of the reinforcement element (2) of the lever (1) and the lock (3), this bending allows the first section (7) of the device (6) to get in the way (see Figure 3 ) of the path of the actuation cam (5), and therefore said cam (5) is not able to complete its travel for actuating the lock (3).
  • the blocking device (6) is in its standby position, as shown in Figure 2 .
  • the blocking device (6) does not get in the way of the movement of the actuation cam (5), allowing the user to freely open the door.
  • the cam (5) is shown in the non-operated position thereof. If the user actuates the lever (1), the actuation cam (5) would move in a substantially upward movement.
  • the first section (7) of the blocking device (6) is caused to move from the standby position to the blocking position, said blocking position being shown in Figure 3 . It is observed that, in this blocking position, the first section (7) gets in the way of a hypothetical upwards movement of the actuation cam (5), making it impossible for the door to be accidentally unlocked.
  • the first section (7) comprises a contact surface (15) suitable for interacting with the actuation cam (5).
  • This contact surface (15) comprises a geometry perpendicular to the direction of movement of the actuation cam (5), thereby ensuring that the first section (7) can properly block the mentioned movement.
  • said contact surface (15) may comprise a geometry complementary to said actuation cam (5), thereby favouring the coupling thereof and making the movement thereof impossible.
  • the articulation segment (11) can be a hinge or a weakened area. Even in the case where the articulation segment (11) is a weakened area, when a thrust is exerted on the projection (10) of the device (6), stresses usually concentrate preferably in the break area (9) (and not in the articulation segment (11)). This means that the device (6) always breaks along the break area (9) and not along the articulation segment (11). This is due to the fact that the break area (9) is located in an intermediate area of the device (6), close to the projection (10), and that in said break area (9) there is a more abrupt change in section of the device (6) in comparison with the articulation segment (11). Nevertheless, it is also possible to make the articulation segment (11) with a greater material thickness than the break area (9), which may also favour the concentration of stresses preferably in the break area (9).
  • the blocking device (6) is configured to break along the break area (9), when the lock (3) presses against the projection (10) in the event deformation due to lateral impact on the vehicle door.
