The present application claims priority to Great Britain Patent Application No. 2114674.1 filed on Oct. 14, 2021 and to Great Britain Patent Application No. 2114673.3 filed on Oct. 14, 2021. The entire contents of each of the above-listed applications are hereby incorporated by reference for all purposes.
The present disclosure relates to an assembly for a vehicle door. The present disclosure also relates to a vehicle door, and a vehicle. In addition, the present disclosure relates to a method of assembling a vehicle door.
The driver and passenger doors of passenger and commercial vehicles typically comprise an external waist seal to prevent water ingress into the interior of the vehicle door via the gap which exists between the uppermost edge of the outer door panel and the moveable glass window. A secondary purpose of the waist seal is to damp vibrations of the glass when it is in the open position and hence located partially or fully within the structure of the door.
Waist seals are typically located along the uppermost edge of the outer door panel such that they fulfil a dual purpose of preventing water ingress and providing an aesthetic trim for the edge of the door panel.
Vehicle styling is of vital importance in the competitive passenger vehicle market, especially so for premium brands that compete not only on vehicle performance but also on superior styling. It is desirable from an aesthetic point of view for the waist seal to be hidden from the view of a vehicle user when the vehicle is viewed by the user in normal use. That is to say, when a user observes the vehicle when it is parked or in motion, when opening and closing the doors, and when driving the vehicle or riding in the vehicle as a passenger.
For the waist seal to be hidden from view, it is necessary to locate it inside the structure of the door below the uppermost edge of the outer door panel. However, this presents a problem as relocation of the waist seal from the uppermost edge of the outer door panel to the interior of the door structure deprives the uppermost edge of the outer door panel of its finishing trim.
This is somewhat less of a problem for frameless doors, such as used for convertible and cabriolet style vehicles, which may be fabricated with a hemmed connection between the outer door panel and the door structure. However, for framed doors found on the majority of roofed vehicles, it is not possible to hem the uppermost edge of the outer door panel as the posts of the window frame prevent access of the hemming tool along the whole width of the uppermost edge of the outer door panel.
It is against this background that the present disclosure has been developed.
Aspects and embodiments of the present disclosure provide a vehicle door assembly, a vehicle door, a vehicle, and a method of manufacturing a vehicle door assembly.
In an aspect there is provided a vehicle door assembly comprising:
an outer door panel skin; and
a seal carrier rail;
wherein the seal carrier rail is shaped to provide:
a first elongate recess at a first face of the seal carrier rail configured to accommodate a waist seal within the first elongate recess; and
a second elongate recess at a second face of the seal carrier rail opposite the first face, wherein the second elongate recess is located between the seal carrier rail and the outer door panel skin.
The first elongate recess provides an upper volume between the door glass, seal carrier rail and outer door panel skin in which to accommodate a waist seal below the upper surface of the outer door panel skin. This arrangement allows the waist seal to be housed behind the upper portion of the outer door panel skin, sheltering it from adverse weather exposure or exposure to dirt, grit or dust, which may cause damage to the waist seal. This also allows the waist seal to be housed out of sight, which improves the aesthetic of the door and vehicle.
The second elongate recess below the first elongate recess forms a lower volume beneath the waist seal The first and second elongate recesses facilitate the use of different types of fastener (e.g. friction-based or threaded fasteners). For example, a nut and bolt fastener arrangement or similar may be used. The head of the bolt may be accommodated in the first elongate recess. A nut may fix the bolt in place to secure the waist seal to the seal carrier rail, and the nut may be accommodated in the second elongate recess. The shape of the second elongate recess may also increase the outer door panel skin stiffness without adding unnecessary weight. The seal carrier rail may be affixed in the door assembly at different points, and the zig-zag/bent cross sectional form of the seal carrier rail may greatly add to door panel skin rigidity and door strength. So, the rigidity of the door is not as dependent on how and where the parts are fixed together, since the form of the seal carrier rail makes a large contribution itself to door rigidity.
In such a vehicle door assembly, a first portion of the seal carrier rail proximal to an upper seal carrier rail edge may be secured to an uppermost portion of the outer door panel skin, the uppermost portion of the outer door panel skin comprising an uppermost outer door panel skin edge. The first elongate recess may be arranged to accommodate a waist seal below said uppermost outer door panel skin edge.
A first portion of the seal carrier rail proximal to an upper seal carrier rail edge may be canted at a first bend in the seal carrier rail.
A channel of the waist seal may be formed by an inner side portion, a support portion, and an outer side portion, and the waist seal may sit inside the upper door panel portion of the door panel skin with the support portion secured to the seal attachment portion of the seal carrier rail. The upper door panel portion thereby hides the waist seal from normal view, or in other words, the seal attachment portion and waist seal are not visible in normal use (i.e.
when a person is walking past, or approaching the vehicle to enter.)
The first portion of the seal carrier rail and an upper seal carrier rail edge proximal to the first portion may be located inside, and secured to the outer door panel skin by, a hemmed connection of the outer door panel skin. The hemmed connection therefore provides an aesthetically pleasing, readily manufactured, strong connection point to fix the seal carrier rail in place in the upper portion of the door panel.
The seal carrier rail may be shaped to form the second elongate recess by comprising:
a first bend between a first portion of the seal carrier rail proximal to an upper seal carrier rail edge and a seal attachment portion of the seal carrier rail to orient the seal attachment portion away from the outer door panel skin, wherein the first portion is aligned coplanar with an uppermost portion of the outer door panel skin;
a second bend between the seal attachment portion of the seal carrier rail and a lower portion of the seal carrier rail to orient the lower portion towards the outer door panel skin; and a third bend between the lower portion and a second portion of the seal carrier rail to orient the second portion coplanar with the outer door panel skin.
The seal carrier rail may be shaped to form the second elongate recess by further comprising a further bend in the seal attachment portion between an upper seal attachment portion of the seal attachment portion and a lower fixing portion of the seal attachment portion, the upper seal attachment portion configured to have a waist seal affixed thereto.
The second elongate channel may thereby form a box-shaped, or polygonal, cross sectional recess, to improve stiffness of the assembly. By improving stiffness characteristics of the door panel, noise, vibration and harshness (NVH) characteristics of the door and vehicle in turn are improved.
The lower portion of the seal attachment rail may be substantially horizontal when installed in a vehicle in a usual orientation i.e. all vehicle wheels contacting horizontal ground. This horizontal arrangement of the lower portion of the seal attachment rail may improve structural stability of the door panel.
The vehicle door assembly may further comprise a waist seal located within the first elongate recess. A bend along the length of the waist seal located between an outer side portion of the waist seal and a support portion of the waist seal may be located within the first bend of the seal carrier rail. This nesting of the waist seal inside the bend, or crook, of the seal carrier rail may provide good structural support to the waist seal, such as when operating the window to move up and down against the sealing limb.
The outer side portion of the waist seal may abut the first portion of the seal carrier rail. The first portion of the seal carrier rail may abut the uppermost portion of the outer door panel skin. Such abutments may contribute to improving the security of the fixing of the waist seal to the seal carrier rail and the fixing of the seal carrier rail to the outer door panel skin.
The vehicle door assembly may further comprise a fixture configured to attach the support portion of the waist seal to a seal attachment portion of the seal carrier rail. The fixture may comprise a head located in the first elongate recess; and a tip opposite the head, the tip located in the second elongate recess. The vehicle door assembly may further comprising a fastener located in the second elongate recess. The fastener may be configured to fit around the tip of the fixture and, with the fixture, secure the waist seal to the seal attachment portion of the seal carrier rail. The fastener may be integrally formed in or on the seal carrier rail.
Such a fixture may be formed to provide structural support, and the presence of the first and second elongated portions of the seal carrier rail provide for design and manufacturing freedom in choosing a suitably shaped and operatable fixture by providing space for portions of the fixture to be located in the door assembly. The fixture may, for example, have a fixture head, such as a bolt head, with a shape extending outwards against the waist seal to support the fixture against the waist seal. Such a fixture head can provide good load spread from the fixing and help to support the outer side portion of the waist seal against the first portion of the seal carrier rail.
The fixture may comprises a head shaped to extend towards one or more of:
a bend along the length of the waist seal between an outer side portion of the waist seal and a support portion of the waist seal; and
a bend along the length of the waist seal between an inner side portion of the waist seal and the support portion of the waist seal.
This fixture head form may help to spread any bending loading caused by friction between the glass and the waist seal which may otherwise typically act to drive seal deflection (lozenging). A broad/extended head of the fastener helps stiffen the base of the waist seal between the inner and outer limbs of the waist seal, further improving performance in use.
The vehicle door assembly may further comprise a waist rail. The waist rail may comprise one or more of:
a first bend between a first waist rail portion and a second waist rail portion, the first bend configured to orient the first waist rail portion coplanar with a seal attachment portion of the seal carrier rail and direct the second waist rail portion towards the outer door panel skin; and
a second bend between the second waist rail portion and a third waist rail portion, the second bend configured to orient the third waist rail portion to be coplanar with and adjacent to the outer door panel skin.
The shape of the waist rail, similarly to the shape of the seal carrier rail, may act to improve door panel assembly stability and stiffness and thus in turn reduce NVH noise. The first bend may be parallel with, and in the opposite direction to, the second bend, in some examples. The second bend may be located adjacent to the outer door panel skin for affixing thereto, for example by a fixing such as an anti-flutter fixing.
The waist rail may be attached to one or more of: the seal attachment portion of the of the seal carrier rail; and the outer door panel skin.
The waist rail may be attached to the seal attachment portion by one or more of:
a fixture fixing the waist rail to the seal attachment portion of the seal carrier rail; and
a waist seal and the seal attachment portion of the seal carrier rail sandwiching an edge of the waist rail therebetween.
The seal carrier rail may be attached to one or more of:
a first fixing point attaching a first portion proximal to a first edge of the seal carrier rail to the outer door panel skin, by a hemmed connection of the outer door panel skin;
a second fixing point of a seal attachment portion of the seal carrier rail to a waist rail; and
a third fixing point of a second portion proximal to a second edge of the seal attachment portion, opposite the first edge of the seal carrier rail, to the outer door panel skin.
In an aspect there is provided a method of manufacturing a vehicle door assembly, the method comprising:
forming a seal carrier rail to comprise:
a first elongate recess at a first face of the seal carrier rail; and
a second elongate recess at a second face of the seal carrier rail opposite the first face;
fixing an outer door panel skin to a first portion of the seal carrier rail by hemming an upper portion of the outer door panel skin over a first edge of the first portion of the seal carrier rail to form a hemmed connection; and
fixing the outer door panel skin to a second portion of the seal carrier rail, the second portion at an opposite side of the seal carrier rail to the first portion,
such that the second elongate recess is located between the seal carrier rail and the outer door panel skin.
The method of manufacturing a vehicle door assembly may further comprise:
accommodating a waist seal below an uppermost outer door panel skin edge of the hemmed connection; and
fixing the accommodated waist seal within the first elongate recess.
In this way, the structurally supportive elements of the vehicle door assembly (i.e. the outer door panel skin and the seal carrier rail) are first assembled including providing a hemmed connection (that is, there is sufficient working space to allow for the manufacture of the door panel assembly by providing the hemmed connection), and this sub-assembly may then be fitted with the waist seal. Thus manufacture is possible to both include the desirable hemmed connection at the top of the door panel assembly, and the waist seal can be accommodated underneath the hemmed connection within the upper portion of the door panel
The method of manufacturing a vehicle door assembly may further comprise fixing a waist rail to the seal carrier rail.

As shown in dashed outline, before the seal carrier rail 140 is attached to the waist rail 150, the fixing elements 185′ project away from the mid-portion 146 of the seal carrier rail 140. To attach the seal carrier rail 140 to the waist rail 150, each fixing element 185′ is passed through a respective aperture 180 in the waist rail 150. The fixing elements 185′ are then folded into position 185 as shown in
Referring now to the waist seal 130 of
The waist seal 130 comprises a second sealing limb 164 located adjacent to the inner-side portion 135 of the waist seal 130 external to the channel 138 formed by the support portion 131, the outer-side portion 133 and the inner-side portion 135. In use, the second sealing limb 164 supports the glass pane 22 when the glass pane 22 is located entirely within the vehicle door 112. The second sealing limb 164 may also support the glass pane 22 when the window is closed or partially open.
The sealing lip 163 located at the distal end 134 of the outer-side portion 133 of the waist seal 130 shown in
In both of the examples discussed above, the waist seals 30, 130 comprise inner-side 35, 135 and outer-side 33, 133 portions that do not touch one another when the waist seal 30, 130 is not installed on a vehicle door 12, 112 such that the channel 38, 138 formed by the support portion 31, 131, the inner-side portion 35, 135, and the outer-side portion 33, 133 form a substantially U-shaped channel. In an alternative embodiment, the waist seal 30, 130 may be formed such that the inner-side portion 35, 135 and the outer-side portion 33, 133 do touch one another when the seal is not installed on a vehicle door 12, 112. In such an embodiment, the inner-sealing limb 61, 161 may still be biased away from the outer-side portion 33, 133 such that it bears against the glass pane 22 when the window is closed or partially open. Alternatively, the inner-sealing limb 61, 161 may not be biased in any direction.
Two methods of attaching the waist seal 30, 130 to the seal carrier rail 40, 140 are described above. As will be clear to a person skilled in the art, the waist seal 30, 130 may be attached to the seal carrier rail 40, 140 by any suitable method including adhesive only or any suitable mechanical fixing including, but not limited to integrally formed or separate: plugs, clips, bolts, tabs and rivets. In addition, the arrangement of mechanical fixings and apertures may be the inverse of that which is described above such that the mechanical fixings may be located on the seal carrier rail 40, 140 and the apertures located in the support portion 31, 131 of the waist seal 30, 130.
Similarly, two methods of attaching the seal carrier rail 40, 140 to the waist rail 50, 150 are described above. As will be clear to a person skilled in the art, the seal carrier rail 40, 140 may be attached to the waist rail 50, 150 by any suitable mechanical fixing including, but not limited to integrally formed or separate: plugs, clips, bolts, tabs and rivets. In addition, the arrangement of mechanical fixings and apertures may be the inverse of that which is described above such that the mechanical fixings may be located on the waist rail 50, 150 and the apertures located in the seal carrier rail 40, 140.
The first elongate recess 138 provides an upper volume between the door glass 22, seal carrier rail 140 and outer door panel skin 26 in which to accommodate the waist seal 130 below the upper surface 720 of the outer door panel skin 26. This arrangement allows the waist seal 130 to be housed behind the upper portion 720 of the outer door panel skin 26, sheltering it from adverse weather exposure or exposure to dirt, grit or dust, which may cause damage to the waist seal 130. There is only a small field of ingress 780 by which the waist seal 130 can be accessed by e.g. dust. This also allows the waist seal 130 to be housed out of sight, which improves the aesthetic of the door and vehicle. In normal use, a person walking past or approaching the vehicle would not see the waist seal 130. Unless a person tries to look almost vertically downwards along the surface of the door glass 22, within a very narrow field of view 780 of a few degrees, then the waist seal is not visible. The upper surface 720 of the outer door panel skin 26 may be considered to comprise at least the portion of the outer door panel skin 26 within which the waist seal 130 is located.
The second elongate recess 760 below the first elongate recess 138 forms a lower volume 760 beneath the waist seal 130. The first 138 and second 760 elongate recesses facilitate the use of different types of fastener 160 (e.g. friction-based or threaded fasteners) as discussed below. For example, a nut or receiver 762 and bolt or fixing plug 160 fastener arrangement or similar may be used. The head 765 of the fixing plug 160 may be accommodated in the first elongate recess 138. A receiver 762 may fix the fixing plug 160 in place to secure the waist seal 130 to the seal carrier rail 140, and the receiver 762 may be accommodated in the second elongate recess 760. The shape of the second elongate recess 760 may also increase the outer door panel skin 26 stiffness without adding unnecessary weight. The seal carrier rail 140 may be affixed in the door assembly 700 at different points, and the zig-zag/bent cross sectional form of the seal carrier rail 140 may greatly add to door panel skin rigidity and door strength. So, the rigidity of the door is not as dependent on how and where the parts are fixed together, since the form of the seal carrier rail 140 makes a large contribution itself to door rigidity.
In such a vehicle door assembly 700, a first portion 41 of the seal carrier rail 140 proximal to an upper seal carrier rail edge 42 may be secured to an uppermost portion 720 of the outer door panel skin 26. The uppermost portion 720 of the outer door panel skin 26 comprises an uppermost outer door panel skin edge 48 which in this example is shown as a folded portion of a hemmed edge of the outer door panel skin 26. The first elongate recess 138 is arranged to accommodate a waist seal 130 below said uppermost outer door panel skin edge 720. The first portion 41 of the seal carrier rail 140 proximal to the upper seal carrier rail edge 42 in this example is canted at a first bend 742 in the seal carrier rail 140.
A channel of the waist seal (within the first elongate recess 138) may be formed by an inner side portion 135, a support portion 131, and an outer side portion 133, and the waist seal 130 may sit inside the upper door panel portion 720 of the outer door panel skin 26 with the support portion 131 secured to the seal attachment portion 146 of the seal carrier rail 140. The upper door panel portion 720 thereby hides the waist seal 130 from normal view, or in other words, the seal attachment portion 146 and waist seal 130 are not visible in normal use (i.e. when a person is walking past, or approaching the vehicle to enter.)
The first portion 41 of the seal carrier rail 140 and an upper seal carrier rail edge 42 proximal to the first portion 41 may be located inside, and secured to the outer door panel skin 26 by, a hemmed connection 48 of the outer door panel skin 26. The hemmed connection 48 therefore provides an aesthetically pleasing, readily manufactured, strong connection point to fix the seal carrier rail 140 in place in the upper portion of the door panel 720. In the examples shown, the first portion 41 of the seal carrier rail 140 and the hemmed connection 48 are angled towards the glass 22 rather than being formed as an upstand from the outer surface of the door skin 26 and are thus not substantially parallel with the door glass 22 as would traditionally be used. By virtue of the waist seal 30 being secured to and supported by the seal carrier rail 40, itself effectively depending from the hemmed connection 48 with the outer door skin 26, the waist seal 30 is arranged below the hemmed connection 48 and is thus does not act as a visible boundary between the door glass 22 and the door skin 26.
The seal carrier rail 140 may be shaped to form the second elongate recess 760 by comprising a first bend 742 between a) the first portion 41 of the seal carrier rail 140 proximal to an upper seal carrier rail edge 42 and b) a seal attachment portion 146 of the seal carrier rail 140. This first bend 742 may serve to orient the seal attachment portion 146 away from the outer door panel skin 26. The first portion 41 is aligned coplanar with an uppermost portion 720 of the outer door panel skin 26. The seal carrier rail 140 may be shaped to form the second elongate recess 760 by comprising a second bend 746 between the seal attachment portion 146 of the seal carrier rail and a lower portion 747 of the seal carrier rail 140 to orient the lower portion 747 towards the outer door panel skin 26. The seal carrier rail 140 may be shaped to form the second elongate recess 760 in some examples by further comprising a further bend 744 in the seal attachment portion 146 between an upper seal attachment portion 146a of the seal attachment portion 146 and a lower fixing portion 147 of the seal attachment portion 146. The upper seal attachment portion 146a is configured to have a waist seal 130 affixed thereto. The seal carrier rail 140 may be shaped to form the second elongate recess 760 by comprising a third bend 748 between the lower portion 747 and a second portion 43 of the seal carrier rail 140 to orient the second portion 43 coplanar with the outer door panel skin 26, for example so it can be fixed thereto by a fixing 70a. The lower portion 747 of the seal carrier rail 140 may be substantially horizontal when installed in a vehicle in a usual orientation i.e. all vehicle wheels contacting horizontal ground. This horizontal arrangement of the lower portion 747 of the seal carrier rail 140 may improve structural stability of the door panel.
The second elongate channel 760 may thereby form a box-shaped, or polygonal, cross sectional recess, to improve stiffness of the assembly 700. By improving stiffness characteristics of the door panel, noise, vibration and harshness (NVH) characteristics of the door and vehicle in turn are improved.
The vehicle door assembly 700 in
The outer side portion 133 of the waist seal 130 may abut the first portion 41 of the seal carrier rail 140. The first portion 41 of the seal carrier rail 140 may abut the uppermost portion 720 of the outer door panel skin 26. Such abutments may contribute to improving the security of the fixing of the waist seal 130 to the seal carrier rail 140 and the fixing of the seal carrier rail 140 to the outer door panel skin 26.
The vehicle door assembly 700 may further comprise a fixture 160 configured to attach the support portion 131 of the waist seal 130 to a seal attachment portion 146 of the seal carrier rail 140. The fixture 160 may comprise a head 765 located in the first elongate recess 138; and a tip 767 opposite the head 765, the tip 767 located in the second elongate recess 760. The vehicle door assembly 700 may further comprise a fastener 762 located in the second elongate recess 760. The fastener 762 may be configured to fit around the tip 767 of the fixture 160 and, with the fixture 160, secure the waist seal 130 to the seal attachment portion 146 of the seal carrier rail 140.
Such a fixture 160 may be formed to provide structural support, and the presence of the first 138 and second 760 elongated portions of the seal carrier rail 140 provide for design and manufacturing freedom in choosing a suitably shaped and operatable fixture 160 by providing space for portions of the fixture 160 to be located in the door assembly 700. The fixture 160 may, for example, have a fixture head 765, such as a bolt- or fixing plug head, with an shape extending outwards against the waist seal 130 (in this example, towards the inner-side portion 135 and outer-side portion 133) to support the fixture 160 (i.e. the head 765) against the waist seal 130. Such a fixture head 765 can provide good load spread from the fixing 160 and help to support the outer side portion 133 of the waist seal 130 against the first portion 41 of the seal carrier rail 140. This fixture head 765 form may also help to spread any bending loading caused by friction between the door glass 22 and the waist seal 130 which may otherwise typically act to drive seal deflection (lozenging). A broad/extended head 765 of the fastener 160 helps stiffen the base (support portion) of the waist seal 131 between the inner 135 and outer 133 portions (limbs) of the waist seal 130, further improving performance in use.
In other examples, a fixture 160 may comprises a head 765 shaped to extend towards one or more of: a bend 732 along the length of the waist seal 130 between the outer side portion 133 of the waist seal 130 and the support portion 131 of the waist seal 130; and a bend 734 along the length of the waist seal 130 between the inner side portion 135 of the waist seal 130 and the support portion 131 of the waist seal 130.
The vehicle door assembly 700 in this example further comprises the waist rail 150. The waist rail 150 in this example comprises a first bend 752 between a first waist rail portion 151 and a second waist rail portion 753. The first bend 752 is configured to orient the first waist rail portion 151 coplanar with a seal attachment portion 147 of the seal carrier rail 140 and direct the second waist rail portion 753 towards the outer door panel skin 26. The waist rail 150 in this example comprises a second bend 754 between the second waist rail portion 753 and a third waist rail portion 755. The second bend 754 is configured to orient the third waist rail portion 755 to be coplanar with and adjacent to the outer door panel skin 26. The first bend 752 may be parallel with, and in the opposite direction to, the second bend 754, in some examples. The second bend 754 may be located adjacent to the outer door panel skin 26 for affixing thereto, for example by a fixing 70b such as an anti-flutter fixing. There may be a further volume 770 formed between the lower portion 747 of the seal carrier rail 140 and the second waist rail portion 753 of the waist rail 150, with the outer door panel skin 26. The shape of the waist rail 150, similarly to the shape of the seal carrier rail 140, may, by way of the bends 752, 754, and the formation of a further volume 770, act to improve door panel assembly 700 stability and thus in turn reduce NVH noise.
The waist rail 150 may be attached to one or more of: the seal attachment portion 147 of the of the seal carrier rail 140; and the outer door panel skin 26. The waist rail 150 may be attached to the seal attachment portion 146 by a fixture 185 fixing the waist rail 150 to the seal attachment portion 146, 147 of the seal carrier rail 140. The waist rail 150 may be attached to the seal attachment portion 146 by the waist seal 130 and the seal attachment portion 146, 147 of the seal carrier rail 140 sandwiching an edge 756 of the waist rail 150 therebetween (the portion 735 of the waist seal 130 sandwiching the waist rail 150 edge 756 is proximal to the second sealing limb 164 of the waist seal 130).
The seal carrier rail 140 may be attached to a first fixing point 782 attaching a first portion proximal 41 to a first edge 42 of the seal carrier rail 140 to the outer door panel skin 26, by a hemmed connection 48 of the outer door panel skin 26. The seal carrier rail 140 may be attached to a second fixing point 185 of a seal attachment portion 147 of the seal carrier rail 140 to the waist rail 150. The seal carrier rail 140 may be attached to a third fixing point 70a of the second portion 43 proximal to a second edge of the seal carrier rail 140, opposite the first edge 42 of the seal carrier rail 140, to the outer door panel skin 26. The fixing 70a may comprise anti flutter material.
A vehicle door 12 may comprise the vehicle door assembly 700 discussed above. A vehicle 10 may comprise the vehicle door assembly 700 discussed above.
The seal carrier rail 40 is shaped as discussed in relation to
In this way, the structurally supportive elements of the vehicle door assembly (i.e. the outer door panel skin 26 and the seal carrier rail 140) are first assembled 902, 904, 906 including providing a hemmed connection (that is, there is sufficient working space to allow for the manufacture of the door panel assembly by providing the hemmed connection), and this sub-assembly may then be fitted with the waist seal 908, 910. Thus manufacture is possible to both include the desirable hemmed connection at the top of the door panel assembly, and the waist seal can be accommodated underneath the hemmed connection within the upper portion of the door panel
