Description

Technical Field

[0001] The subject of the present invention is a device for attaching a trim piece to a body structure of a motor vehicle, such as a window pillar, in particular near the area housing at least a portion of an inflatable curtain device. Background Art

[0002] In most vehicles, a lining part (also called a trim part) conceals one or more inflatable elements (commonly called inflatable curtains) for lateral protection of the occupants.

[0003] The folded inflatable curtain, which is typically wrapped around itself, the triggering device, and the straps intended to hold and guide the inflatable curtain in position in the vehicle during deployment of the inflatable curtain may be located beneath the trim.

[0004] The trim must allow the inflatable curtain and straps to pass unhindered from beneath the trim toward the interior of the passenger compartment.

[0005] The trim is held to the vehicle's body structure using attachment features. These attachment features must retain the trim in a passive position in the lining of the passenger compartment and, where appropriate, must allow the passage of an inflatable curtain. Furthermore, the release of the curtain must not unfasten or damage the trim, which must remain at least partially secured to the vehicle body structure.

[0006] Depending on the configuration of the vehicle, particularly when the windshield has a large surface area, it may be desirable to use inflatable curtains that are partially housed behind the window pillar trim and above the roof lining. In this configuration, the window pillar trim tends to pop out toward the interior of the passenger compartment, which is undesirable.

[0007] There are systems for preventing the ejection of trim. Most of these systems prove to be relatively complex and expensive. Moreover, these systems sometimes, even if they allow the ejection of trim to be avoided, do not adequately protect the trim, so that parts of the trim may be damaged and ejected inside the passenger compartment, which is also undesirable.

[0008] Therefore, there is a need for an attachment device that allows both at least one portion of an inflatable curtain device and a liner portion to be retained and allows the inflatable curtain to be deployed without damaging or unravelling the liner portion. Summary of the invention

[0009] To this end, a first subject of the invention relates to a device for attaching a trim element to a body structure of a motor vehicle, in particular a window pillar, said attachment device comprising a clip shaped to receive at least one portion of an inflatable curtain device, wherein the clip comprises:

[0010] - a first clip part provided with an attachment element for attachment to a vehicle body structure;

[0011] - a second clip part provided with an attachment element for attachment to a trim element;

[0012] - the two clamping parts are connected together by an articulation member and a locking member, the articulation member and the locking member being arranged so that the deployment of the inflatable curtain disengages the locking member and causes the second clamping part to pivot relative to the first clamping part about said articulation member;

[0013] And among them:

[0014] - the locking means comprises locking lugs, and a retaining element for retaining the locking lugs in mutual engagement in the closed position of the clip, the locking lugs and the retaining element being fixed to the separate clip parts;

[0015] the hinged part comprises at least one hook and at least one opposing hook, which in the open position of the clip are engaged with each other and are kept in engagement with each other by at least one elastic band and are blocked in rotation by at least one stop, the hook being fixed to one clip part and the opposing hook, the elastic band and the stop being fixed to the other clip part; and

[0016] - A hook forms one end of the locking lug and, in the closed position of the clip, an opposing hook forms a retaining element for this locking lug and is held in engagement by an elastic band with an engagement zone of said locking lug, which engagement zone is located at a predetermined distance from the hook.

[0017] The arrangement of the articulated means of the clip allows obtaining an opening greater than that caused by a simple rotation of the two clip parts, which facilitates the release of the inflatable curtain by reducing the forces to which the second clip part is subjected. In fact, during the disengagement of the locking means, the two clip parts are moved in the vicinity of the articulated means and during the rotation by a distance equal to the distance separating the end of the hook forming the engagement part from the locking lug forming the hook. In other words, the second clip part pivots while moving away from the first clip part.

[0018] Furthermore, by virtue of the two-part configuration of the clip, the second clip part attached to the trim creates a reinforcement and protection for the trim during deployment of the inflatable curtain. Thus, the trim is no longer in direct contact with the inflatable curtain device. The attachment of the trim to the second clip part strengthens the trim and also reduces the risk of damage.

[0019] Furthermore, this two-part configuration allows the production of safe and economical locking and hinge components, provided that these components are fixed to the clip part and not to a relatively large lining part, such as a window pillar trim. It is also possible to provide the two clip parts with different materials and / or structures depending on the resistance required for each part.

[0020] Typically, in the operational position of the clip attached to the vehicle body structure, the second clip portion may pivot relative to a direction substantially parallel to a plane defined by the vehicle body structure (eg, substantially parallel to a longitudinal direction of the vehicle body structure).

[0021] Advantageously, the locking means may be arranged at opposite ends of the two clip parts, in particular in the longitudinal direction of the clip. In the operating position of the clip, this longitudinal direction may be defined as a direction substantially perpendicular to the longitudinal direction of the vehicle body structure.

[0022] Advantageously, one or more locking parts, for example two locking parts, may be provided at only one end of the clip, in particular the lower end in the operating position of the clip, and a hinge part may be provided at the other end of the clip, in particular the upper end in the operating position of the clip.

[0023] Advantageously, the hinged part may comprise two stops located on either side of the elastic band. This may stabilize the second clamping part during its opening. This may also improve the retention of the engagement between the hook and the opposing hook.

[0024] Advantageously, in addition to the opposing hooks, an elastic band can keep the non-hooked locking lugs engaged with the retaining elements, the elastic band being fixed to the clip portion supporting these retaining elements. This can facilitate locking the clip in the closed position.

[0025] In particular, the elastic band of the locking lug can be connected to the clip portion by a thin material area. This can facilitate the disengagement of the locking member during deployment of the inflatable curtain.

[0026] Advantageously, the second clip part may include an area with different stiffness, the hinge part being fixed to such an area having a stiffness lower than the stiffness of the area fixed to the locking lug without hook. The lower stiffness near the hinge part may facilitate the opening of the clip, while the greater stiffness may improve the function of strengthening and protecting the trim provided by the second clip part.

[0027] For example, the area with lower rigidity may comprise a wall without reinforcing ribs, the shape of which substantially follows the shape of the trim to which it is intended to be attached. The area with greater rigidity may be a structured wall comprising, for example, one or more reinforcements selected from ribs, recessed areas and protruding areas perpendicular to its surface.

[0028] Advantageously, the second clip portion may comprise an area defining a surface forming a slope extending up to an edge of the second clip portion, the surface having a shape capable of guiding a portion of the inflatable curtain device in the longitudinal direction of the second clip portion during deployment of the inflatable curtain beyond said edge of the second clip portion. This may facilitate protection of the trim during deployment of the inflatable curtain, in particular when the second clip portion is configured to completely cover an end edge of the trim, in particular in an area close to the locking lug without hook. Advantageously, said edge of the second clip portion may be the edge opposite to the edge provided with the hinged part.

[0029] The invention also relates to a subassembly for an interior lining of a motor vehicle, comprising a trim for a window pillar and an attachment device according to the invention, wherein the first clip portion is attached to the window pillar and the trim is attached only to the second clip portion. Thus, the trim, reinforced and protected by the second clip portion, is no longer directly connected to the window pillar and is no longer in contact with the inflatable curtain device, which allows limiting the risk of damage to the trim during deployment of the inflatable curtain device.

[0030] In particular, the window pillar (respectively the trim piece) may comprise attachment elements which cooperate with elements for attaching the first clip portion (respectively the second clip portion).

[0031] Advantageously, at least one upper attachment element can be provided for the trim, for example near the hinge part, and at least one lower attachment element can be provided, especially near the lower edge of the trim. For better retention, two lower attachment elements can be provided, especially at the same distance from the lower edge of the trim.

[0032] Advantageously, at least one upper attachment element may be provided for the window pillar, for example in the vicinity of the hinge component, and at least one other attachment element may be provided remote from the upper attachment element.

[0033] Advantageously, in order to better protect the trim during deployment of the inflatable curtain, the second clip portion may completely or almost completely cover the end edge of the trim. In particular, the second clip portion may completely cover the area of ​​the end edge of a portion of the inflatable curtain rubbed during deployment of the inflatable curtain. Generally speaking, the portion of the inflatable curtain rubbed on this area is the portion installed under the window pillar trim.

[0034] Advantageously, for a better appearance, the subassembly may include indexing components fixed to the second clip part and the trim, the indexing components being configured to ensure the relative positioning of these parts. In particular, the indexing components may be arranged between two lower attachment elements for attaching the second clip part to the trim.

[0035] A further subject of the invention is a motor vehicle comprising a window pillar, an inflatable curtain device comprising an inflatable curtain and a retaining strip, and at least one lining subassembly according to the invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] In this specification, the terms front, rear, top, and bottom refer to the forward and rearward directions of the vehicle, the top and bottom of the vehicle when the window pillar, the attachment device, and the window pillar trim are installed on the vehicle. The X, Y, and Z axes correspond to the longitudinal (from front to rear), transverse, and vertical axes of the vehicle, respectively, when the vehicle is parked on the ground. Therefore, the vertical direction corresponds to the direction of gravity.

[0046] By substantially horizontal, longitudinal or vertical is meant a direction / plane which forms an angle of at most ±20°, even at most 10°, with a horizontal, longitudinal or vertical direction / plane.

[0047] In the following, the attachment device according to the invention will be described for attaching a trim element to a vehicle body structure forming a window pillar (in this case a windshield), which is an application for which the attachment device is particularly suitable. However, the invention is not limited to this type of window pillar (where the pillar may be the rear window of a motor vehicle) nor to a vehicle body structure forming a window pillar.

[0048] Figure 1 A window pillar 1, a roof 2 of a vehicle, and an inflatable curtain device 3 are partially shown. The inflatable curtain device 3 comprises in particular an inflatable curtain 4 in a folded position (in this case, wound on itself), and a retaining strip 5. This retaining strip 5 is inserted between the window pillar 1 and the curtain 4 in order to keep the curtain in place during its deployment. Typically, the curtain 4 extends over the upper part of the front and rear doors (not shown) of the vehicle and is intended for lateral protection of the passengers in the event of an accident. In the example shown, the curtain 4 also extends partially in the vicinity of the window pillar 1, while the strip 5 extends almost exclusively along the window pillar 1.

[0049] In this case, the window pillar 1 is formed by assembling two parts 1 a , 1 b , which are usually made of sheet metal. Figure 3 and Figures 6 to 8 The windshield 7 and the seals 8 and 9 (only in FIG. 1 ) respectively located between the windshield 7 and the window pillar 1 and between the window pillar 1 and the trim 6 of the window pillar 1 are shown. Figures 6 to 8 (see ).

[0050] The attachment device 10 allows the inflatable curtain device to be attached to the window pillar 1. In this case, the attachment device 10 is arranged on the window pillar 1 next to the roof 2. In this case, the attachment device 10 forms a clip shaped to at least partially accommodate the curtain 4 and the retaining strip 5. The attachment device 10, the window pillar 1 and the trim 6 form a subassembly 40 for an interior lining of a motor vehicle.

[0051] According to the invention, the attachment device 10 forming a clip comprises a first clip part 11 provided with attachment elements for attachment to the window pillar 1 and a second clip part 12 provided with attachment elements 14A, 14B for attachment to the trim 6 .

[0052] The two clamp parts 11 and 12 are connected to each other by a locking part 15 and a hinge part 16. Figure 1 , Figure 6 , Figure 7 As shown, when the two clamp parts 11 and 12 are assembled in the clamp closed position, the two clamp parts together define a space E ( Figure 6 , Figure 7During the unfolding of the curtain 4, said curtain exerts pressure on the locking means 15, which disengages the locking means and causes the clip to open. In the open position of the clip caused by the unfolding of the curtain 4 ( Figure 8 ) the two clamp parts 11 , 12 are held together only by the hinge part 16 .

[0053] In other words, the hinge member 16 and the locking member 15 are arranged such that deployment of the inflatable curtain 4 disengages the locking member 15 and causes the second clamp portion 12 to pivot about the hinge member 16 relative to the first clamp portion 11 .

[0054] In this example, the locking members 15 are arranged at opposite ends of the clip in the longitudinal direction L of the clip ( Figure 1 ). This longitudinal direction L extends substantially perpendicularly to the longitudinal direction L′ of the window pillar 1 .

[0055] The locking member 15 includes a locking lug 15A i and retaining element 15B i , these retaining elements are used to hold the locking lugs in engagement with each other in the closed position of the clip, where i is a non-zero integer representing the number of locking lugs. Each locking lug 15A i is fixed to one of the clamping parts, and the corresponding holding element 15B i In the example shown, the locking member 15 comprises an upper locking lug 15A1 and two lower locking lugs 15A2, 15A3. The upper locking lug 15A1 is fixed to the second clamp part 12, while the lower locking lugs 15A2, 15A3 are fixed to the first clamp part 11.

[0056] Each locking lug 15A i including a holding element 15B configured to i Cooperative joint part 15C i This joint portion 15C i This may be in the form of a curled edge 15C2, 15C3, particularly at one end of the locking lug, as shown on the lower locking lug 15A2, 15A3 ( Figure 2 and Figure 7 ), or even in the form of a shoulder 15C1, in particular at a certain distance from the end of the locking lug, such as Figure 3 and Figure 4 As shown for the upper locking lug 15A1.

[0057] Holding element 15B i The engaging portion 15C may be formed with the locking lug i These retaining elements 15B are in the form of abutment stops. i The opening 15D can be provided through the corresponding clamp portion. iThe edge formation ( Figure 2 , Figure 3 , Figure 5 , Figure 7 ). Elastic band 17 i This allows the locking lug 15A to i With holding element 15B i Staying in touch has been improved.

[0058] In the example shown, the lower locking lugs 15A2, 15A3 fixed to the first clamping part 11 are held in abutment with retaining elements 15B2, 15B3 fixed to the second clamping part 12 by elastic bands 172, 173, which are also fixed to the second clamping part 12. More specifically, the second clamping part 12 has openings 15D2, 15D3, the lower edges of which form the retaining elements 15B2, 15B3, and the elastic bands 172, 173 are connected to the upper edges of these openings. The bands are in the form of lugs, for example, connected to the second clamping part 12 by a thin material area 18, which makes it elastic. This thin material area 18 also forms a hinge for the bands 172, 173. Therefore, when the curtain 4 is unfolded in the direction of the arrow F and exerts pressure on the second clamping part 12 ( Figure 8 ), each elastic band 172, 173 pivots around the thin material area 18 forming the hinge in the direction opposite to the lower locking lugs 15A2, 15A3, thereby facilitating the disengagement of the lower locking lugs from the corresponding retaining elements 15B2, 15B3 and the disengagement of the locking means. The second clamping portion 12 released at the bottom can open the curtain 4 during deployment and allow the curtain to pass.

[0059] The hinge members 16 will now be described. As regards the hinge members, these hinge members include at least one hook 16A and an opposing hook 16B that are connected and engaged with each other in the open position of the clip. Figure 3 and Figure 4 As can be seen in the figure, the hook 16A forms one end of the upper locking lug 15A1, the engagement portion of which extends at a predetermined distance from the hook-shaped end. This distance can be selected so as to obtain a spacing between the two clip parts sufficient to allow the curtain 4 to leave during its unfolding. In the example, when the hook 16A is attached to the second clip part, the hook bends upwards towards the decorative element 6. This arrangement promotes the retention of the hook when the clip is completely opened.

[0060] In the open position of the clip, the hook 16A is held in engagement with the opposing hook 16B by the elastic band 171 and is blocked in a rotational sense by two stops 19 provided on either side of the elastic band 171. It should be noted that the opposing hook 16B, the stop 19 and the elastic band 171 are fixed to the first clip part 11, with the opposing hook 16B positioned facing the elastic band 171 and the stop 19. This arrangement of the stop relative to the elastic band ensures proper retention of the hook; however, other arrangements are also conceivable, for example including a single stop.

[0061] In the present example, the opening 15D1 of the first clamp portion 11 has an edge (in this case, the upper edge) forming the opposing hooks 16B (and also the retaining element 15B1), and the other edge (in this case, the lower edge) is provided with a stopper 19 and an elastic band 171. The distance separating the stopper 19 from the opposing hooks 16B is sufficient to allow the locking lug 15A1 provided with the hooks 16A to be locked in place. Figure 3 When the upper locking lug 15A1 is inserted, the elastic band 171 exerts a force on the upper locking lug 15A1, thereby pushing it towards the opposite hook 16B, 15B1, so that the hook engages with the engagement portion of the locking lug in the form of a shoulder 15C1 ( Figure 6 ).

[0062] During the disengagement of the lower locking lugs 15A2, 15A3, the pressure exerted thereon by the curtain 4 causes the second clamping part 12 to move downwardly in the direction of the arrow F, so that the upper locking lug 15A1 presses on the elastic band 171, thus releasing the engagement portion in the form of the shoulder 15C1 from the opposite hook 16B. The second clamping part 12 can then continue to move in the direction of the arrow F until the hook 16A engages with the opposite hook 16B. The unfolding of the curtain also causes the second clamping part 12 to rotate to a position in which the upper locking lug 15A1 is blocked in a rotational sense by the stop 19 ( Figure 3 ). In this position, the second clip portion 12 cannot be released from the first clip portion 11 , so that the trim 6 attached to the second clip portion 12 remains fixed to the window pillar 1 .

[0063] The second clamp portion 12 also comprises areas 12A, 12B of different stiffness in order to facilitate the opening of the clamp, in particular sufficient to allow the curtain 4 to leave the clamp.

[0064] In particular, the hinge member 16 is fixed to the region 12A, which has a lower rigidity than the region fixed to the locking lugs 15A2, 15A3 without hooks. In other words, the second clip portion 12 has an upper portion near the hinge member 16, which has a lower rigidity than the lower portion supporting the locking member 15. Therefore, during the opening of the clip, the region 12A with lower rigidity will tend to deform, while the region 12B with greater rigidity will not deform, thus providing effective reinforcement for the trim 6.

[0065] The second clamping portion 12 also includes a region 12C defining a surface S forming a slope extending up to an edge 12D of the second clamping portion 12. Figure 4 , Figure 8 ). This surface S is shaped so that it can guide a portion of the inflatable curtain device 3 (curtain 4 and / or retaining strip 5) beyond the edge 12D of the second clamping portion during deployment of the inflatable curtain 4. Figure 8 As shown, this surface S is substantially flat at least in the vicinity of the trim attachment elements 14A, 14B and the indexing member 30 .

[0066] like Figures 6 to 8 As shown, the second clip portion 12 completely covers the end edge 20, in particular the lower edge, of the trim 6. In the example shown, the edge 12D of the second clip portion 12 covers the end edge 20. More specifically, this end edge 20 is adjacent to the edge 12D, for example so that the second clip portion 12 covers the lower corner of the trim 6 (directed towards the inflatable curtain) and a 30 mm to 80 mm portion of the end edge of the trim 6, against which the portion of the inflatable curtain mounted below the window pillar trim rubs when leaving. Thus, during the opening of the clip, the trim 6 remains attached to the second clip portion 12 near the upper end (near the hinge 16), while its lower part is completely reinforced and protected by the second clip portion 12, for which purpose the surface S of the ramp 12C also guides the curtain 4 and / or the strip 5 towards the outside of the clip without any risk of getting caught with the trim 6. Thus, the curtain 4 can be deployed without the risk of unravelling or damaging the trim 6.

[0067] As previously mentioned, the first clip part 11 is provided with attachment elements for attachment to the window pillar 1. In the example shown, this involves attachment lugs 13A, 13B, 13C, which are arranged to engage with corresponding apertures of the window pillar 1. Two of these attachment lugs 13A, 13B are located at substantially the same distance from the upper edge of the first clip part 11. The third lug 13C is located next to the opening 15D1. It should therefore be noted that the lugs 13A, 13B are substantially located in the vicinity of the curtain 4 and / or the strip 5, which can facilitate the retention of the first clip to the window pillar during deployment of the curtain 4. It should also be noted that there is a lug 21 fixed to the first clip part 11, which allows a pipe or cable 22 to be retained in the space E ( Figure 2 , Figure 3 , Figure 6 , Figure 8 ). This is particularly advantageous in view of the reduced space available between the window pillar 1 and the trim 6 .

[0068] The second clip part 12 for its part is provided with attachment elements 14A, 14B for attachment to the trim part 6. In this example, three attachment elements 14A, 14B, 14B are provided. The first attachment element 14A is in the form of an attachment clip which is shaped to be inserted into a corresponding opening 23 of the second clip part ( Figure 7 ), the edges 23A, 23B of the opening forming an elastic band which abuts on either side of the widened end 24 of the attachment clip 14A. This allows a relatively strong attachment to be provided. It should be noted that in the example shown, this attachment element 14A is located between an area of ​​lower rigidity 12A and an area of ​​higher rigidity 12B of the second clip part. Therefore, during the unfolding of the curtain 4, the area for the attachment clip 14A is not deformed, thereby reducing the risk of uncoupling the decorative element. Two attachment elements 14B are also provided on the decorative element, essentially facing the area of ​​greater rigidity 12B of the second clip part. This involves an attachment lug having a curling edge at its free end which engages with one end of a lug 25, 26 provided on the second clip part 12 ( Figure 5 , Figure 7 ). In this case, the lugs 25, 26 are located above the lower locking part 15 of the second clamping part. In the example shown, the lugs 25, 26 are attached to the upper edges of the openings 27, 28 of the first clamping part 11, respectively ( Figure 5 ).

[0069] Of course, the invention is not limited to the specific arrangement of attachment elements described with reference to the figures, nor to a specific number of said elements, as long as the clip can be attached to the window pillar and the trim.

[0070] like Figure 5As shown, the second clamping part also has a number of ribs 29 perpendicular to its surface, which contribute to the rigidity of the region 12B of the second clamping part 12. These ribs may also define the surface S of the ramp 12C.

[0071] Finally, indexing members 30 , 31 are provided to ensure the relative positioning of the decorative element 6 and the second clamping portion 12 .

[0072] In the example shown, this involves an indexing member 30 in the form of a finger fixed to the decorative element (in particular forming part thereof), which finger is inserted into an indexing member 31 in the form of a cavity provided for this purpose on the second clamping part 12. In this example, the indexing member 30 in the form of a finger abuts the lower and upper edges of the indexing member 31 in the form of a cavity, thereby ensuring that the decorative element 6 is positioned in the longitudinal direction of the clamp. In this case, the indexing member 31 in the form of a cavity is defined by the rib 29 and the projection 32 of the second clamping part. These various elements also contribute to the rigidity of the area 12B. The invention is not limited by the shape and number of the indexing members, which are preferably provided in the vicinity of the area 12B of the second clamping part.

[0073] In other words, the elements (locking means 15, opening 23, attachment lugs 25, 26, ribs 29, protrusions 32) arranged in the vicinity of the zone 12B of the second clip portion provide this zone with a certain amount of rigidity sufficient to allow it to fulfill its role as a trim reinforcement and which is greater than the rigidity of the zone 12A without any attachment elements. Contrary to the highly structured shape of the lower part of the second clip portion 12, extending the locking lugs 15A1 into the extension of the wall forming the zone 12A contributes to the flexibility of this zone. It is therefore preferred to position the attachment elements for attachment to the trim, as well as the locking means and optionally the indexing means and the ramp, in the vicinity of the zone 12B of the second clip portion, in its lower part.

[0074] Therefore, the attachment device according to the invention allows to provide a safe and economical attachment of a decorative element. The attachment device can also be produced in a relatively simple manner. In particular, each clip part can be made of a part made of a polymer material, for example by molding.
