Description

Title of the invention: Sealing device for a motor vehicle's opening door technical field

[0001] The invention relates to a sealing device for an open door - in particular of a rear opening door of a motor vehicle. The invention relates in particular to a sealing device shaped to establish a watertight seal between said opening door and a wheel arch extending opposite said opening door. Previous technique

[0002] A sealing device for a through door is known, shown in cross-section in [Fig. 1] in the closed position of the through door and in [Fig. 2] in the open position of the through door. The known sealing device shown comprises a rubber profile 1' having a longitudinal rib 2' which, in any straight cross-section, has a generally T-shaped profile extending along the entire length of the rubber profile 1' and adapted to cooperate with a longitudinal groove 3' running the entire length of a rigid support 4'. Assembling the rubber profile 1' and the rigid support 4' by sliding the T-shaped rib 2' longitudinally into the longitudinal groove 3' running the length of the rigid support 4' is difficult and hinders the optimization of the time required to assemble the sealing device and the through door.

[0003] The invention aims to overcome this drawback.

[0004] Furthermore, the rubber profile 1' of this known sealing device, shown in cross-section in [Fig. 2] in an elastically extended state (the said opening door being open), is symmetrical about its median plane 5' and is arranged to cooperate by compression ([Fig. 1]) with a substantially flat section 6' of the body side, located at a distance from a hem 7' bordering the wheel arch 8'. This compression of the profile 1' certainly forms a barrier between the wheel arch 8' and the vehicle's passenger compartment 9' against dirt projected by the rotation of the wheels, but it also allows, in a very disadvantageous way, an accumulation of such dirt on another section 10' of the body side, extending just behind the hem 7'. Such an accumulation of dirt and / or the deterioration of the paintwork that may result from this accumulation is likely to impair the Perceived Quality of the motor vehicle.

[0005] The invention aims to overcome this drawback.

[0006] Throughout this text, the term "through door" means a motor vehicle door where at least one peripheral edge section of the door, when the door is in the closed position, is aligned with a body or chassis edge defining a wheel arch—particularly a rear wheel arch—of that motor vehicle. In other words, a "through" door of a motor vehicle is a door that substantially covers the entire side of the vehicle's body and extends at least partially into the area of ​​a wheel arch.

[0007] The peripheral edge of the opening door and the bodywork edge delimiting the corresponding wheel arch constitute a prime entry point for dirt (water, dust, solid particles, gravel, etc.) thrown up by the rotating wheel when the motor vehicle is moving on a traffic lane. This dirt can accumulate on at least one part of the motor vehicle's bodywork opposite the door in the closed position, particularly on the drip edge.

[0008] On the one hand, these soilings are in themselves likely to impair the Perceived Quality performance of the motor vehicle.

[0009] The invention aims to overcome this drawback.

[0010] Furthermore, since these are solid and abrasive materials, this soiling is likely to damage the vehicle's paintwork due to its accumulation between the door and the part of the vehicle's bodywork against which the closed door extends, and due to the vibrations caused by the moving vehicle and the abrasive nature of the soiling. This damage, particularly these scratches, to the paintwork is also likely in itself to impair the Perceived Quality of the vehicle.

[0011] The invention aims to overcome this drawback.

[0012] The invention aims to overcome all of these drawbacks.

[0013] The invention therefore aims to provide a sealing device for an opening door of a motor vehicle whose assembly is facilitated.

[0014] The invention also aims to provide such a joint device which is formed from components which can be manufactured on an industrial scale and which are inexpensive.

[0015] The invention also aims to provide such a joint device enabling a good Perceived Quality performance. Description of the invention

[0016] To this end, the invention relates to a sealing device for an opening door of a motor vehicle, the sealing device comprising: - a rigid support comprising means for securing the rigid support and said opening door by clipping, - a tubular joint elastically deformable in radial compression, integral with the rigid support and having a base maintained in contact with the rigid support and an apical ridge opposite the base, the base and the ridge forming the tubular joint, characterized in that, according to any straight cross-section of the tubular joint, the apical crest is laterally offset relative to the median of the base so that the tubular joint deformed by a hem (delimiting a wheel arch) on one side of the body of the motor vehicle, due to the closing of the opening door, fills - in particular completely fills - a space extending between the hem and an edge, called the outer edge, longitudinal of the rigid support, said outer edge extending substantially opposite a sector of the peripheral edge of said opening door.

[0017] Throughout the text, - The terms "hem" or "crimped" refer to the result of the crimping operation used in the automotive industry, which consists of folding an edge of the outer skin of the motor vehicle back on itself or on an internal reinforcement, thus optimizing the final geometry of this outer skin, improving its resistance and rigidity, and mitigating the risk of cuts caused by this outer skin edge. - the terms "front", "rear", "right", "left", "lower", "upper", "top" and "bottom" are to be considered in relation to a vehicle in normal condition to move forward, - the XYZ reference frame refers to a direct orthonormal XYZ reference frame classically used in automotive design, in which the X axis designates the front-to-back longitudinal direction of the vehicle, oriented towards the rear, the Y axis designates the transverse direction and is oriented towards the right of the vehicle, the Z axis designates the vertical direction, and is oriented upwards.

[0018] According to the invention, the tubular seal is arranged and shaped to cooperate with the hem portion forming the wheel arch extending opposite said opening door. According to the invention, with the vehicle door closed, the tubular seal cooperates with the hem portion forming the wheel arch extending opposite said opening door, whereby the tubular seal is deformed by the hem and fills the space extending between the hem of the wheel arch and the peripheral edge sector of said opening door. As a result, the drip edge is protected from dirt that may be thrown up by a wheel of the moving motor vehicle. The accumulation of such dirt in this space is prevented, the risks of paint degradation on the drip edge are limited and the Perceived Quality service is maintained.

[0019] According to the invention, the anti-soiling function of the sealing device is performed on the hem and not on a substantially flat surface of the drip edge. The paint on the drip edge is not damaged and the Perceived Quality performance is maintained.

[0020] The rigid support is shaped to longitudinally cover the peripheral edge sector of said opening door, extending opposite a portion of a body edge delimiting the wheel arch.

[0021] According to the invention, the apical crest of the tubular joint is laterally offset relative to the median of the base at least in an open state of the through door, the tubular joint being in a state not crushed by the through door and elastically brought back into this uncrushed state.

[0022] According to certain embodiments, the means for securing the rigid support and said through door comprise at least one element for securing the rigid support and said through door by clipping. According to these embodiments, the element for securing the rigid support and said through door is a element for securing the rigid support and said through door that cooperates with said through door by elastic deformation.

[0023] According to certain embodiments, the tubular seal is an extruded tubular seal. The industrial production of an extruded tubular seal precursor is facilitated and carried out at a lower cost, the tubular seal being obtained by transverse cutting of the tubular seal precursor to the required length.

[0024] According to some embodiments, the base of the tubular joint has a plurality of through eyelets, each through eyelet being adapted to receive an assembly member of the tubular joint and the rigid support, each assembly member being adapted to cooperate with one of the through eyelets of the tubular joint and with a through hole in the rigid support.

[0025] According to certain advantageous embodiments, each assembly member is an assembly member of the tubular joint and the rigid support by clipping (elastic deformation).

[0026] According to some embodiments, the base of the tubular joint comprises 5 to 10 through eyelets, in particular 6 to 7 through eyelets.

[0027] According to certain embodiments, the rigid support is a rigid support formed from two bi-injected polymer materials. Bi-injection production, also known as two-component plastic injection molding, makes it possible to produce, using a single press, a rigid support made of polymer materials with different functional characteristics. Industrial production of the rigid support is therefore facilitated.

[0028] According to some embodiments, the rigid bi-injected support is formed of a first hard thermoplastic material - in particular polypropylene - and a second thermoplastic elastomer material.

[0029] According to certain embodiments, the rigid bi-injected support is formed of a main part comprising the means for securing the rigid support to said opening door by clipping and of an additional thickness extending substantially orthogonally to said main part.

[0030] According to some embodiments, the main part is formed of polypropylene and said overthickness is made of at least one thermoplastic elastomer material.

[0031] According to some embodiments, said opening door of the motor vehicle is a rear opening door of the motor vehicle. However, nothing prevents it from being provided, according to other embodiments, that said opening door of the motor vehicle is a front opening door of a motor vehicle, in particular a commercial motor vehicle.

[0032] In some embodiments, said inward-opening door is a hinged door. In some embodiments, said inward-opening door is a combination door. In some embodiments, said inward-opening door is a framed door. In some embodiments, said inward-opening door is a combination hinged and inward-opening door.

[0033] The invention extends to a motor vehicle with a through-door comprising at least one sealing device according to the invention. Brief description of the drawings

[0034] Other features and advantages of the invention will become apparent from the following description. This description is not exhaustive, is purely illustrative, and should be read in conjunction with the accompanying drawings, in which:

[0035] [Fig-1] [Fig.1] is a cross-sectional representation of a known device of the prior art, of sealing a motor vehicle door, said door being folded down in a closed state,

[0044] [Description of figures 1 and 2 representative of the known prior art]

[0045] Figures 1 and 2 are cross-sectional representations of a device 1' of sealing a rear swinging door 11' of a motor vehicle, known from the prior art. In [Fig. 1], said swinging door 11' is in a closed position for the passenger compartment of the motor vehicle. The door 11' has a crimped edge 13' forming a peripheral edge of said swinging door 11'. Said swinging door 11' is called a "swinging" door because a longitudinal sector of this peripheral edge formed by the crimped edge 13' extends opposite a hem 7' on one side 6' of the vehicle body, the crimped edge 13' and the hem 7' creating a space opening directly onto this wheel arch 8'.In the closed position of the opening door, the gap between the crimped edge 13' and the hem 7' opens onto the wheel well 8', such that the rotation of the wheel of a vehicle moving on a traffic lane causes dirt to be thrown towards and into the gap between the hem 7' and an outer edge 14' of a rigid support 4' attached to the opening door 11'. This results in an undesirable accumulation of such dirt in a space 15' delimited by a rubber profile 1', a body side 6', and the rigid support 4'. The rigid support 4' is attached to the opening door 11'. The rigid support 4' has a main portion 12' comprising means (not shown) for attaching the rigid support 4' to the opening door 11'.

[0046] In [Fig. 2], said opening door 11' is in an open position of the passenger compartment of the motor vehicle in which the crimped seal 13' extends at a distance from the hem bordering the wheel arch. In this open position of said opening door, the sealing device 1', elastically returned to an undeformed state, presents, in any longitudinal position of the sealing device 1', a plane 5' of symmetry in which extends a median apical ridge 16' of the device 1' of sealing. Such a symmetrical sealing device 1', known in the prior art, does not allow the gap between the opening door 11' and the hem 7' to be filled by crushing the sealing device 1'. It does not fully meet the requirements of a good Perceived Quality performance.

[0047] [Description of embodiments of the invention]

[0048] Figure 3 illustrates the definition of a door 2 of a motor vehicle 20. The rear detail of the motor vehicle 20 shown in Figure 3 shows a right rear door 2 of a motor vehicle 20. The door 2 has a peripheral edge sector 23 which also forms part of the edge of a wheel arch 19 21. The peripheral edge sector 23 is a lower rear sector 23 of said door 2. The door 2 has another upper rear peripheral edge sector 25 extending opposite a front peripheral edge 24 of one side 10 of the body of the motor vehicle 20. As can be seen in [Fig.3], the lower rear sector 23 of the peripheral edge of the opening door 2 forms with the edge portion of the wheel passage 19 21 a contact zone extending in a substantially vertical plane and orthogonal to the axis of rotation of the wheel 21.Thus, due to the rotation of the wheel 21 of the moving vehicle 20, dirt is likely to be projected in a direction substantially orthogonal to the axis of rotation of the wheel 21, and in particular in the direction and onto the contact area. Such projections are likely to impair the Perceived Quality of the vehicle 20.

[0049] Figure 4 is a detail view of the inner face of a left-hand rear opening door 2 of a motor vehicle 20. The opening door 2 is equipped with a sealing device 1 according to the invention, mounted integrally with a lower rear section of the peripheral edge of the opening door 2. The sealing device 1 according to the invention comprises a rigid support 3 supporting a tubular seal 5 along its entire length. The rigid support 3 forms a main portion 17 intended to be secured to said opening door 2 and an additional thickness 18 intended to extend opposite the wheel arch 19. The main part 17 of the rigid support 3 is laterally limited by an edge, called the external edge 12, extending near a sector of the peripheral edge of said opening door 2 and by an edge, called the internal longitudinal edge 30, extending opposite said external edge 12.The main part 17 has means 4 for securing the main part 17 and the rigid support 3 to the open door 2. The securing means 4 comprise a plurality of securing elements 13 regularly distributed along the entire length of the rigid support 3 and near said internal longitudinal edge 30. The securing elements 13 can be of any type. The connection between the open door 2, the rigid support 3, and the adjoining device 1 is thus ensured. The main part 17 of the rigid support 3. It also features a tubular seal 5 extending from a free principal face of the rigid support 3, which is fixed to the opening door 2, along the entire length of the rigid support 3 and close to and substantially parallel to said outer edge 12 of the rigid support 3. The tubular seal 5 is thus fixed to the opening door 2 and extends over the peripheral edge sector 23 of the opening door 2, extending opposite a portion of the edge (not shown) of a wheel arch 19 when the opening door 2 is in the closed position.

[0050] Figure 5 is a cross-sectional view along plane BB of the jointed device 1 according to the invention shown in Figure 4. In Figure 5, the jointed device 1 is mounted integrally with a door 2 of a motor vehicle 20, the door 2 being in the open position. In the embodiment shown, the door 2 has an outer skin 32 forming an external face of the door 2 and an inner skin 29 integrally with the outer skin 32 by a crimp 22 of the outer skin 32. The rigid support 3 is mounted integrally with the door 2 by fastening means 4 comprising a plurality of fastening members 13 regularly distributed along the entire length of the main part 17 of the rigid support 3 and near said inner longitudinal edge 30 of the rigid support 3.In the embodiment shown, the joining element 13 of the rigid support 3 and the openable door 2 comprises an elastically deformable pin 26 adapted to cooperate with an eyelet 27 formed in the rigid support 3 and with a hole 28 made in the inner surface 29 of the openable door 2, and to secure the rigid support 3 by clipping the pin 26 into the opening of the hole 28. The attachment of the rigid support 3 to the openable door 2 is thus facilitated. The main part 17 of the rigid support 3 also has a plurality of holes 16 passing through the rigid support 3. The holes 16 passing through the plurality of holes are regularly distributed longitudinally near the peripheral edge 12 of the rigid support 3.

[0051] The sealing device 1 according to the invention comprises a tubular seal 5 shown in cross-section in [Fig. 5]. The tubular seal 5 is elastically deformable under radial compression. It can be made of any suitable material to allow the formation, particularly by extrusion, of a long length of a tubular seal precursor that can be cut transversely into sections sized to form the tubular seal 5. The production of the tubular seal 5 is thus technically facilitated and economically optimized. The tubular seal 5 has, in any cross-section, a substantially flat base 6 extending along the entire length of the tubular seal 5 and adapted to be maintained in contact with the rigid support 3. The base 6 has two longitudinal lips 35 ensuring the sealing of the contact between the tubular seal 5 and the rigid support 3 assembled together by means of of a plurality of assembly members 15. The base 6 has a plurality of eyelets 14 passing through the base 6, the eyelets 14 passing through the plurality of eyelets being regularly distributed along the entire length of the base 6 and the tubular joint 5. Each eyelet 14 passing through is dimensioned to be able to receive and cooperate with an assembly member 15 of the tubular joint 5 and the rigid support 3. In the embodiment shown, each assembly member 15 has a head 33 dimensioned to be held in contact with an internal face 36 of the base 6 and a clippable (elastically deformable) body 34 adapted to be inserted into a bore 16 passing through the rigid support 3 and to cooperate elastically with the bore 16 to create a connection, in particular a liquid- and solid-tight connection, between the rigid support 3 and the tubular joint 5.The base 6 is extended radially by a portion 37 of a complementary envelope to the base 6 and forming, with the base 6, the tubular joint 5.

[0052] In the free and radially uncompressed state of the tubular seal 5 as shown in [Fig. 5], the portion 37 of the tubular seal 5's envelope presents, in any straight transverse section, an apical ridge 7 extending opposite the base 6. According to the invention, the apical ridge 7 is offset laterally with respect to the perpendicular bisector 8 of the base 6 in the free and radially uncompressed state of the tubular seal 5. In certain embodiments, the apical ridge 7 is offset towards the peripheral edge sector 23 of the opening gate 2.As will be described in view of the following figures, the offset of the apical ridge 7 of the tubular seal 5 allows the tubular seal 5 to be deformed by a hem 9 on one side 10 of the body of the vehicle 20 automobile due to the closing of the opening door 2, the hem 9 deforming the tubular seal 5 not by contact of the apical ridge 7 of the tubular seal 5 with the hem 9 and support of the apical ridge 7 of the tubular seal 5 on the hem 9, but by contact of a lateral face 38 of the portion 37 of complementary envelope of the base 6 with the hem 9 and support of a lateral face 38 of the portion 37 of complementary envelope of the base 6 on the hem 9.Due to the offset of the apical ridge 7, the deformation of the tubular seal 5 includes a deformation component directed along a direction parallel to the perpendicular bisector 8 of the base 6 of the tubular seal 5 (crushing of the tubular seal 5), but also a non-zero deformation component directed towards the outer edge 12 of the rigid support 3. Because of this deformation of the tubular seal 5 when the opening door 2 is closed, the additional envelope portion 37 of the base 6 fills the space extending between the hem 9 and the outer edge 12 of the rigid support 3. Dirt projected by the rotation of the wheel cannot accumulate in this space, and the Perceived Quality performance is optimized.

[0053] In the embodiment shown in [Fig. 5], said outer edge 12 of the main part 17 of the rigid support 3 forms two tabs 39 opposed to each other and extending from said outer edge 12 substantially orthogonally to the principal plane of the main part 17. In the embodiment shown, the main part 17 and the opposing tabs 39 are formed of the same material. For example, the material forming the main part 17 and the opposing tabs 39 of the rigid support 3 is polypropylene. In the embodiment shown in [Fig. 5], the rigid support 3 has an additional thickness 18 covering the opposing tabs 39 and extending beyond the tabs 39. Advantageously, the additional thickness 18 is made of at least one thermoplastic elastomer material. The additional thickness 18 made of thermoplastic elastomer material provides support for the tubular seal 5, at least during its deformation when the opening door 2 is closed. According to these embodiments, the rigid support 3 is a rigid support formed of two bi-injected polymer materials.The production of rigid support 3 using bi-injection, also known as two-material plastic injection, allows for the production of a rigid support 3 made of polymer materials with different functional characteristics using a single press. Industrial production of rigid support 3 is therefore both possible and facilitated.

[0054] Figures 6, 7, 8, and 9 are cross-sectional views of a detail of a tubular seal 5 of a sealing device 1 according to the invention, shown in successive relative positions of the opening door 2 with respect to the edge 23 of the wheel arch 21, during the closing of the opening door 2. In the embodiments shown in Figures 6, 7, 8, and 9, the edge 23 of the wheel arch 21 is schematically represented in a simplified manner by the hem 9 forming the edge 23.

[0055] In [Fig. 6], the opening door 2 is in a partially open state and the sealing device 1 according to the invention extends at a distance from the hem 9 forming the peripheral edge portion 23 of the wheel arch. The tubular seal 5 is not deformed by the hem 9 and the apical ridge 7 is offset relative to the perpendicular bisector 8 of the base 6 of the tubular seal 5.

[0056] In [Fig.7], the opening door 2 is in a partially open state and the tubular seal 5 of the sealing device 1 according to the invention is in contact with the end of the hem 9. Due to this contact and the progressive closing of the opening door 2, the tubular seal 5 is deformed by the indentation of the lateral face 38 of the complementary portion 37 of the base 6 of the tubular seal 5 due to the contact of this lateral face 38 and the hem 9.

[0057] Due to this contact and the progressive closing of the opening gate 2 and due to the displacement of the apical ridge 7, the deformation of the tubular seal 5 includes a deformation component directed along a direction parallel to the perpendicular bisector 8 of the base 6 of the tubular seal 5 (crushing of the tubular seal 5), but also a non-zero deformation component directed towards said external edge 12 of the rigid support 3. The support of the tubular joint 5 on the rigid support 3, in particular on the opposite tabs 39 of the rigid support 3 and / or on the overthickness 18, is increased and the deformation and sinking of the tubular joint 5 is amplified.

[0058] In [Fig.8], the open door 2 is in a fully closed state and the tubular seal 5 of the sealing device 1 according to the invention is at the end of its travel relative to the end of the hem 9. Due to the complete closure of the open door 2, the tubular seal 5 is deformed by the indentation of the lateral face 38 of the tubular seal 5 due to this complete closure. Due to this complete closure of the opening door 2 and due to the offset of the apical ridge 7, the lateral 38 of the tubular seal 5 forms a contact that is at least watertight against liquids and solids with the hem 9 forming the edge of the wheel passage 19 21. In addition, due to this complete closure of the opening door 2 and due to the offset of the apical ridge 7, the face of the tubular seal 5 opposite to the lateral face 38 forms a contact that is at least watertight against liquids and solids with the rigid support 3 and with the crimped 22 of the opening door 2.The space between hem 9 and seam 22 is filled so that dirt cannot accumulate in this space and the Perceived Quality performance is validated.

[0059] Fig. 9 is an illustration of a direct orthonormal XYZ coordinate system classically used in automotive design (according to standard no. 0100112), in which the X axis designates the front-to-back longitudinal direction of the motor vehicle, oriented towards the rear of the motor vehicle, the Y axis designates the transverse direction and is oriented towards the right of the motor vehicle, the Z axis designates the vertical direction, and is oriented upwards towards the motor vehicle, the wheels of the motor vehicle being oriented downwards.
