Description

ISOFIX ANCHORAGE ARRANGEMENT
Technical Field
The present invention relates generally to an Isofix anchorage arrangement for a vehicle, and particularly though not exclusively an Isofix anchorage provided in a seat arrangement for a vehicle, e.g. an automobile.
Background
Passenger vehicles are usually equipped with one or more passenger seats that include Isofix anchorages to which can be secured child car seats. Typically, a bottom Isofix anchorage is provided in the nip between a seat base and a seat back. The child car seat may include a connection arm that extends rearwardly to hook securely onto the bottom Isofix anchorage thereby releasably fixing the child car seat in place. Beneficially, the Isofix anchorage is associated with the vehicle body and so is considered to be a hard point for safe mounting of child car seats.
In addition to the Isofix bottom anchorage, it is usually necessary to provide an Isofix top anchorage. Usually, this anchorage is positioned behind the passenger seat, for example on a hard-mounted parcel shelf or rear bulkhead of the vehicle or in a rear-facing surface of the passenger seat itself. A child car seat is secured to the Isofix top anchorage by way of a so-called top tether, which is a length of flexible fabric strap that extends from the top of the child car seat, over the top of the passenger seat to thereby hook onto the Isofix top tether anchorage by way of a suitable clip or hook device. The purpose of this is to secure the top of the child car seat to the car body so that in the event of a vehicle impact the child car seat is not able to rotate forward forcefully. Best practice for child safety, therefore, is to secure the child car seat with both top and bottom Isofix anchorages.
Usually, Isofix anchorages take the form of anchor bars or rods which are welded to the internal structure of the seat. Such a design tends to be adequate from a strength perspective. However, this approach requires one or more specific manufacturing steps and associated quality checks. It is desirable to make manufacturing and assembly as efficient as possible so it is with these issues in mind that the embodiments of the invention have been devised.
Summary of the Invention 1.
Against this background, a first aspect of the invention provides an Isofix anchorage arrangement comprising an interior vehicle panel which defines an Isofix anchorage, wherein the Isofix anchorage includes an aperture which penetrates the interior vehicle panel and thereby defines an internal edge, wherein at least a portion of the internal edge defines a gripping bead configured to be gripped by a Isofix connecting fixture, in use.
An advantage of the invention is that the configuration of the anchorage integrates the anchor point in the interior vehicle panel itself, thereby avoiding the need for further components such as welded anchor bars. This means that the Isofix anchorage is simplified, leading to reduced mass of the arrangement and a more efficient manufacturing process.
In one embodiment, the interior vehicle panel is a seat back unit of a vehicle seat unit.
The bead may be a lip that projects from the adjacent part of the panel to the aperture. The lip may be formed in any suitable way and it may be any suitable shape. It may have an annular cross section for example, and in one embodiment may be circular in cross section. The generally annular form may be achieved by a forming process involving rolling a part of the edge in on itself to create the bead.
By virtue of the rolling process, the bead may define an internal chamber or lumen. This chamber may be left empty or it may be utilised, advantageously, to receive a stiffening core therein. The stiffening core may be embodied as a wire, rod or other similar component around which the internal edge of the aperture may be rolled during manufacture.
The aperture itself may be any suitable shape but is preferably generally rectilinear in form, and in one embodiment, may be generally trapezoidal in form. Selected vertices of the internal edge that defines the aperture may be curved so as to avoid stress concentrations at relevant areas.
In one embodiment, the aperture may be formed in a recessed panel portion defined in the panel. The recessed panel portion may be offset from the surrounding panel plane by a suitable distance, for example between 2mm and 15mm, more preferably between 5mm and 10mm. Forming the aperture in an offset region in this way is a further measure to increase strength and stiffness.
In a second aspect, the invention provides a method of manufacturing an Isofix anchorage, comprising: providing an interior vehicle panel defined by a generally planar sheet of rigid material and forming an aperture in the interior vehicle panel defined by an internal edge. One the aperture has been formed, a gripping bead is then formed along at least a portion of the internal edge of the aperture.
The gripping bead may be formed by folding a section of the panel in the region of the aperture back on itself to define the gripping bead. By virtue of the folding or rolling, the folded section of the panel may be shaped so as to have an annular cross section.
Beneficially, the folding/rolling process creates strength in the panel so that the edge of the aperture is suitable for attaching to an Isofix top tether hook. The gripping bead may be further strengthened by capturing a strengthening core inside the folded section whilst it is being formed. The strengthening core may be a rod or wire for example.
A further strengthening measure can be achieved by forming an offset region that extends about the aperture and which is offset a predetermined depth from a major plane of the panel. Still further, a ridge may be formed in the panel that extends about the offset region. The ridge may be offset in a different direction to the offset region.
Further optional and advantageous features are referenced in the detailed description and the appended claims.
Brief Description of the Drawings
In order for the invention to be better understood, embodiments of the invention will be described in detail by way of example only with reference to the following drawings, in which: Figure 1 is a schematic view of the vehicle seat arrangement that shows the general layout of a seat base and a seat back in relation to a child car seat supported on the seat arrangement. An Isofix top tether extends from the child car seat over an upper part of the seat back and to an anchorage point in the rear of the seat back.

Detailed description of the embodiments
The invention relates generally to an Isofix anchorage in an interior vehicle panel. That panel may be part of the vehicle structure such as in a rigid parcel shelf in a sedan-style vehicle or as part of a main structure for a vehicle seat. In the case of a vehicle seat, the seat back panel provides a mounting for various safety, functional and comfort related features that are required from the vehicle seat. Isofix anchorages for top tethers can be challenging to integrate into interior vehicle panels. Current solutions required a number of manufacturing steps to be carried out which increases assembly time and also time for quality inspection of weld joints and the like. The invention provides a solution to reduce manufacturing complexity whilst retaining the effectiveness of the anchorage within the panel and, in particular, integrates the anchorage in the panel without the usual anchor bars and similar rod-like components.
The illustrated embodiments show the invention in the context of a vehicle seat. However, it should be noted at this point that the invention is also applicable to panel in other parts of the vehicle, such as read bulkheads and rigid parcel shelf components.
In order to put the embodiments of the invention into a useful context, reference will firstly be made to Figure 1. In Figure 1, a vehicle seat arrangement 2 includes a seat base 4 and a seat back 6. Here, the seat back 6 is shown as being pivotable about the seat base 4 by way of a pivot point 8. Note that a pivoting seat back is not essential to the invention but is a feature customarily provided in vehicle seat arrangements.
As shown, a child car seat 10 is supported on the vehicle seat arrangement 2, resting on the seat base 4 and against the seat back 6. Such a child car seat 10 may be secured to the vehicle seat arrangement 2 by way of a first Isofix anchorage 11 defined in the nip between the seat base 4 and the seat back 6. In the illustrated embodiment, the child car seat 10 is also secured in place by an Isofix top tether anchorage 12 that is defined by the seat back 6.
The top tether anchorage 12 provides a secure anchoring point for a top tether 14 of the child car seat 10 which extends from an upper part of the child car seat 10 over the top of the seat back 6 and to the top tether anchorage 12.
Each of the seat base 4 and the seat back 6 includes structural components that provide strength and comfort. In this respect, the seat base 4 include a seat base frame 20 and a seat base cushion 22. The seat base frame 20 may be formed of one or more frame sections such as tubular members and generally planar panels or sheets. However, the overall function of the seat base frame 20 is to provide a secure mounting for the seat arrangement 2 and structure and support for the seat base cushion 22. General forms of seat base frames and cushions are known in the art and so further discussion will be omitted for brevity.
Turning to the seat back 6, in a similar way to the seat base 4 it may include various structural members such as tubular members and planar panel parts that define a seat back frame 24 which supports a seat back cushion 26. In general, both types of seat structural components are known in the art, although recent advances in seat design have shown that using panels to define the main structural member for the seat back has advantages in terms of weight savings whilst still providing the required strength properties.
An example configuration of seat back is shown in more detail in Figure 2. It is to be noted that Figure 2 is schematic in form and so may not include all features of a practical seat back for a vehicle. The seat back 6 in Figure 2 features a known configuration of top tether anchorage 12 which, although not the focus of this invention, is provided in the discussion here so that the invention may be more readily understood.
As can be seen in Figure 2, the seat back 6 includes the seat back frame 24 comprising a combination of structural features including a tubular frame member 30 and a seat back panel 32. A lower edge of the seat back frame 24 includes a reclining mechanism 34 which provides the pivoting motion of the seat back 6. The reclining mechanism 34 is not the focus of the invention and so will not be described in more detail.
The tubular frame member 30 is generally rectangular in this embodiment and defines curved corners. The tubular frame member 30 is fixed to the seat back panel 32 in any suitable manner, but preferably is welded to the seat back panel 32. Other attachment methods may be via any combination of bolts, clips, clamps or bonding substances, to name a few examples.
The shape and configuration of the tubular frame member 30 contributes to the overall strength characteristics of the seat back 6 and provides improved flexural rigidity to the generally planar form of the seat back panel 32. It may also be considered to apply tension across the seat back panel 32 thereby increasing strength.
The seat back panel 32 may be formed from a pressed sheet of suitable material such as aluminium, steel, carbon fibre, fibre reinforced plastic, or a composite. Such a pressed construction achieves a desirable strength to weight ratio from of a relatively thin sheet of material, for example around 0.5mm to 2mm in thickness. To improve strength characteristics and rigidity the seat back panel 32 may be formed with a configuration of strengthening features such as ribs, recesses, offsets and so on. The seat back panel 32 may also be provided with mounting points such as apertures to which other components may be attached, such as seat cushion parts, heating/ventilation components, and wiring loom components. Apertures may also be provided for mass reduction purposes. Some of these features are shown in the inset panel in Figure 2.
Central to the inset panel of Figure 2 is shown the lsofix anchorage 12. As can be seen the lsofix anchorage 12 includes an upright rectangular aperture 36 across which extends a rodlike anchor bar 38. The anchor bar 38 includes a central portion 40 which is flanked by first and second fixing portions 42, 44 which are angled with respect to the central portion 40. The central portion 40 extends transversely across the aperture 36 approximately parallel to upper and lower edges of the aperture 36. The fixing portions 42, 44 serve to attach the anchor bar 38 to the panel 32 and this fixing may be by any suitable means, although a welded fixing is generally preferred for its strength. As can be seen in Figure 2 the fixing portions 42, 44 are affixed to respective mounting bosses 45.
The anchor bar 38 provides a connection point to which can be attached a tether clip or hook which is associated with a top tether strap. As shown in Figure 1, the top tether is flexible and extends from the child car seat 10 over the upper part of the seat back 6 to attach to the anchorage 12. The connection is achieved by way of a hook or clip 46 as is known in the art, and as is shown in the inset panel view of Figure 2.
A limitation of the design shown in Figure 2 is that the configuration of anchor bar 38 requires fixing to the seat panel 30. Although this provides a convenient connection point, it requires an additional manufacturing step with the associated drawbacks of the required welding processes and quality checking to ensure that the welds are good.
The embodiments of the invention propose an alternative configuration of anchorage that are suitable for being incorporated into the seat panel previously described.
With reference now to Figures 3 to 5, a vehicle seat arrangement 50 in accordance with an embodiment of the invention comprises a seat back 52 defined by a seat back frame 52 having a seat back panel 54 and a tubular frame member 56. A reclining mechanism 58 is provided at the lower part of the seat back 50 but is not the focus of the invention so will not be discussed further. The general configuration of the seat back 52 is the same as that in Figure 2.
The seat back panel 54 includes a Isofix top tether anchorage 60, which is shown in more detail in the inset image in Figure 3. As can be seen the top tether anchorage includes an aperture 62 that penetrates the seat back panel 54. However, when compared with the top tether anchorage 12 in Figure 2, it will be appreciated that it does not include a separate anchor bar. Instead, the Isofix anchorage is defined by an internal edge 64 of the aperture 62 by the formation of a gripping bead 66 that extends along at least a portion of the internal edge 64.
It will be appreciated that the gripping bead 66 projects from the otherwise flat surrounding material of the seat back panel 54 to provide an upstanding lip, hem, projection or rim to which an Isofix clip can be attached. Figure 4 shows a top tether hook 65 engaged with the gripping bead 66.
The gripping bead 66 can be formed in various ways. In one approach, the bead 66 may be formed by an accumulation of material along the required portion of the intemal edge 64, for example as may be achieved by way of a welding process. Alternatively, a bar or rod may be welded to the internal edge 64 of the aperture 62.
In a currently preferred embodiment, the gripping bead 66 may conveniently be formed by way of a rolling process during which a portion of the internal edge 64 is folded or rolled over on itself during manufacture. This can be appreciated more fully by observing the cross-section view of Figure 4 in which it can be seen that the gripping bead 66 is formed by the sheet material of the panel being rolled over at its edge. In this example the gripping bead 66 is formed with a generally circular cross-sectional profile, which approximates the shape of the anchor bar 38 of the prior art. A precise circular cross section profile is not necessary but is a function of the rolling process. In generally, an annular form is acceptable as this will create the increased strength in the otherwise planar sheet.
One option, as shown in Figure 4, is for the gripping bead 66 to accommodate a stiffening core 68 inside the internal chamber 70 that is formed when the bead 66 is rolled. One option is for the stiffening core to be formed from a piece of metal wire, rod or similar material that gets integrated into the gripping bead 66 during formation.
Beneficially, the shaping of the internal edge 64 of the aperture 62 to create the rounded lip of the gripping bead 66 greatly increases the buckling strength of the material around the aperture 62 which makes it suitable for being a structural tethering point for a top tether hook. Figure 4 demonstrates that the gripping bead 66 provides a positive retention point for the Isofix tether hook 65. Moreover, this structure simplifies the manufacture because it does not require any welding or similar processes to affix a separate anchor rod across the aperture as is the case with the configuration described above with reference to Figure 2.
What is also notable in the Figures is that the aperture is formed in a recessed region 72 of the channel. The recess region 72 surrounds the aperture 62 and is generally square in the illustrated embodiment. The purpose of the recessed region 72 is to provide the seat back panel 54 with improved strength and stiffness in the area around the aperture 62. The recessed region 72 may be formed by a pressing process during manufacture of the panel.
The offset depth of the recessed region 72, when measured in a distance perpendicular to the major plane P of the panel 54 may be any suitable dimension to achieve the required stiffness. However, it is envisaged that depths of around 2mm to 15mm would be appropriate, and more particularly between 5mm and lOmm, by way of example. The offset depth is shown as D1' in Figure 4. Although the general shape of the recessed region 72 is rectilinear, and generally square in this embodiment, its corners are smoothly curved so as to avoid stress concentrations. The recessed region helps to ensure that the profile of the gripping bead 66 does not protrude beyond the main plane of the panel.
Still further, immediately outside the recessed region 72, there may be formed an inverse recess 73 which is offset from the major plane P of the panel 54 in the opposed direction from the recessed region 72. In effect, this creates a raised ridge around the recessed region 72, with an offset dimension marked on Figure 4 as 02.
Turning to the aperture 62 in more detail, it will be appreciated that the aperture 62 is rectilinear in form, and is generally trapezoidal, in this embodiment. In this respect, the internal edge 64 of the aperture 62 has a lower edge portion 80, an upper edge portion 82 and two side portions 84, 86. Here, it is an inverted trapezoidal shape such that the lower and upper edge portions 80, 82 are parallel to each other, although the lower edge portion 80 is shorter in length than the upper edge portion 82. The upper edge portion 82 is flanked by the respective side portions 84, 86 which extend therefrom and converge towards the lower edge portion 80. The vertexes between the side portions 84, 86 and the upper edge portion 80 are curved smoothly so there is no sharp transition. This avoids stress concentrations in this general area and helps the rolling process of the gripping bead 66. It should be noted that although the aperture 62 is shown with a generally trapezoidal shape in the illustrated embodiment, this is not essential and other shapes would be acceptable that permit accessibility to the hook 65. For example, the aperture 62 may have a generally rectangular profile similar to that shown in Figure 2.
The invention may also be expressed as a method of manufacturing a seat arrangement to include the Isofix anchorage as described above. With reference to Figure 6, a representative method 100 in accordance with the invention includes step 102 in which a seat back panel 54 or a blank therefor is provided. Show here the seat back panel 54 is flat but it should be appreciated that it may bear appropriate pressing formations for strength and other purposes.
Step 104 includes forming an aperture 62 in the seat back panel. The aperture 62 may be formed in any suitable way, for example by laser cutting, high pressure fluid cutting or by stamping.
Step 106 includes forming at least a portion of the internal edge 64 to define a gripping bead 66. This step is depicted in two stages where it can be seen that a section of the panel surrounding the aperture 62 is rolled back on itself to create an annular profile for the gripping bead 66. Optionally a strengthening core 68 can be captured in the gripping bead 66 as it is formed.
The illustrated embodiments demonstrate one way in which the invention may be performed and some variants have been discussed above. The skilled person would appreciate that other minor modifications may be made to the specific embodiments without departing from the inventive concept as defined by the claims.
