Definitions
- the present invention relates to a seat component with a trim cover fastener for attaching a trim cover to a cushion.
- Seat components typically include a trim cover, usually made of some type of flexible upholstery sheet such as fabric or synthetic leather, attached to a cushion.
- the cushion used for occupant seating is usually constructed with at least one trench or groove, and more typically with several trenches or grooves on its upper surface.
- Two ends of upholstery sheet are typically connected to each other to form a seam. Sewing the two ends of upholstery sheet together, or some other suitable attaching means typically holds the seam together.
- the seam fits into the trenches of the cushion and is attached such that the upholstery sheet is generally fixed in position.
- Some current methods for attaching the seam to the cushion involve the use of hog rings.
- the seam is typically attached to a series of hog rings, which are then attached to a metal wire that runs through the cushion generally parallel to the upper surface of the cushion.
- This process may be difficult to use because it requires inserting the wire through the cushion in order to provide the support needed for the hog rings.
- the process used for attaching the hog ring to the support wire may be cumbersome, and the materials used may be expensive compared to other alternatives.
- Another method involves hooks and loops such as attaching a male strip of Velcro® to the seam, and attaching a female strip of Velcro® within the trenches in the cushion. The seam can then be secured within the trench by the Velcro® strip.
- a potential problem with this method is that because of the inherent readily releasable nature of Velcro®, the seam may become unintentionally detached from the cushion. Maintaining proper alignment of the seam may also be difficult when using Velcro®.
- Yet another method involves using some form of adhesive to attach the upholstery sheet seam to the cushion within the trenches. But this technique can pose a relatively significant problem if the seat component needs to be reupholstered, as adhesives are intended to be permanent attachments. Maintaining proper alignment of the seam may be difficult with adhesives as well.
- the present invention provides a seat component comprising a cushion, a trim cover having at least one seam, and a unitary trim cover fastener for attaching the trim cover seam to the cushion.
- the trim cover fastener has a first end attached to the trim cover seam and a second end extending into at least a portion of, and attached to, the cushion.
- the present invention further provides a method for securing a trim cover to a cushion.
- the method comprises securing a first end of a unitary trim cover fastener to a trim cover, inserting a second end of the trim cover fastener into at least a portion of the cushion and securing the second end of the trim cover fastener to the cushion.
- the present invention further provides a seat component comprising a cushion having a first side spaced from a second side, a trim cover having at least one seam, and a plastic trim cover fastener for attaching the trim cover seam to the cushion.
- the trim cover fastener has a first end attached to the trim cover seam adjacent the first side of the cushion and a second end adjacent and secured to the second side of the cushion.

- the trim cover 12 does not have to be directly adjacent the cushion 8 , as other materials or fabrics may be placed between the trim cover 12 and the cushion 8 .
- the first end 24 of the trim cover fastener 22 is secured adjacent the first side 18 of the cushion 8 at a position located at or near the vertex of the cushion trench 16 . It is also important to note that although FIG.
- the first end 24 of the trim cover fastener 22 may also be attached above the trim cover seam 14 , such that the connector portion 28 has a portion that extends above the trim cover seam 14 .
- the first end 24 of the trim cover fastener 22 could be on the outer surface of the trim cover 12 .
- the trim cover fastener 22 can be secured to the trim cover 12 and the cushion 8 in any suitable manner.
- One suitable manner is to attach the first end 24 of the trim cover fastener 22 to the trim cover seam 14 and then attach the second end 26 of the trim cover fastener 22 to the second side 18 of the cushion 8 , as shown in FIG. 3 .
- One way of inserting the second end 26 of the trim cover fastener 22 into at least a portion of the cushion 8 involves using a cut-through needle.

- FIGS. 6B and 6C show the trim cover fastener 22 with the second end 26 in a scrolled state in greater detail.
- the second end 26 of the trim cover fastener 22 is then loaded into a cut-through needle.
- the cut-through needle, loaded with the second end 26 of the trim cover fastener 22 is inserted all the way through the cushion 8 . This can create the hole 38 through the cushion 8 that extends between the first 18 and second 20 sides, as shown in FIG. 3 .

- the second end 26 of the trim cover fastener 22 rotates 90 degrees such that the longest dimension 36 is positioned parallel to the second surface 20 of the cushion 8 , as shown in FIG. 6B .
- the second end 26 of the trim cover fastener 22 typically expands such that it is in the expanded state shown in FIG. 6A . This process may then be repeated using one or more other trim cover fasteners 22 to secure one or more other parts of the trim cover seam 14 to the cushion 8 near the vertex of a trench 16 .
- the trim cover seam 14 may be attached to a tie-down portion 30 .

- the trim cover seam 14 may be sewn to the first end 32 of the tie-down portion 30 , or any other suitable attaching means may be used.
- the tie-down portion 30 and the attached trim cover seam 14 may be positioned in the cushion trench 16 .
- the first end 24 of the trim cover fastener 22 is attached to the second end 34 of the tie-down portion 30 .
- the first end 24 of the trim cover fastener 22 is typically secured adjacent the first side 18 of the cushion 8 .
- the second end 26 of the trim cover fastener 22 is then typically inserted into at least a portion of the cushion 8 and is secured to the cushion 8 , such as at the second side 20 of the cushion 8 .
- tie-down portion 30 helps keep the trim cover seam 14 together, which allows the trim cover fasteners 22 attaching the trim cover seam 14 to the cushion 8 to be spaced farther apart from each other. It also helps protect the upholstery material from being damaged during the attachment process, since only the tie-down portion 30 will be directly attached to the cushion 8 . In addition, when removing the trim cover fasteners 22 for reupholstering purposes, the trim cover seam 14 remains intact if a tie-down portion 30 is used. The tie-down portion 30 will also help create an even seam and maintain proper alignment. Because the trim cover 12 is typically made of some type of fabric, the trim cover seam 14 may not be able to withstand pointed forces.
- Sewing a tie-down portion 30 along the trim cover seam 14 will help distribute the pointed forces associated with the attachment to the trim cover faster 22 , along the length of the trim cover seam 14 . And because the tie-down portion 30 is typically reinforced along the edge with a thermoplastic polymer, it will be able to withstand relatively greater pointed forces than the trim cover seam 14 alone.
- the first end 24 and second end 26 of the trim cover fastener 22 are adjacent the first 18 and second 20 sides, respectively, of the cushion 8 .
- the connector portion 28 typically extends through the cushion 8 between the first side 18 and the second side 20 .
- the cushion 8 may have a hole 38 on at least the second side 20 of the cushion 8 having two dimensions. Typically, at least one dimension of the second end 26 of the trim cover fastener 22 is longer than at least one dimension of the hole 38 .
- the first end 24 of the trim cover fastener 22 is in the shape of a solid cylinder. In the embodiments shown in FIGS.
- the second end 26 of the trim cover fastener 22 is in the shape of a hollow half-pipe.
- the trim cover fastener 22 described in the present invention may have portions, such as the first and second ends 24 and 26 , of any suitable shape and/or size.
- the second end 26 of the trim cover fastener 22 may be released within the cushion 8 before reaching the second side 20 of the cushion 8 .
- the cut-through needle does not extend to the second side 20 of the cushion 8 .
- FIGS. 5A and 5B the trim cover fastener 22 of the present invention is shown with the second end 26 extending into only a portion of, and attached to, the cushion 8 between the sides 18 and 20 .
- the second end 26 of the trim cover fastener 22 may be made of a material that can be compressible, as mentioned above. This allows the second end 26 of the trim cover fastener 22 to be compressed into a scrolled state, as further shown in FIG. 6B . Compressing the second end 26 of the trim cover fastener 22 decreases the surface area of the second end 26 so that it may more easily be inserted into the cushion 8 . Referring to FIGS. 5B and 6A , the second end 26 of the trim cover fastener 22 has at least one dimension 36 longer than at least one dimension of the hole 38 . In this embodiment, the second end 26 of the trim cover fastener 22 may be attached to the cushion 8 .
- This attachment can typically be achieved by orienting the second end 26 of the trim cover fastener 22 in such a way that it is prevented from moving through the hole 38 towards the first side 18 of the cushion 8 .
- One approach is to provide a slot 40 , which the second end 26 of the trim cover fastener 22 fits into, as shown in FIG. 5C .
- Another approach is to provide the second end 26 of the trim cover fastener 22 with compressible fins 42 that can extend into slots 40 , as shown in FIG. 5D .
- the fins 42 are compressed during the insertion process, but can expand into the slots 40 when the second end 26 of the trim cover fastener 22 is in the appropriate position.
- Other appropriate means for attaching the second end 26 of the trim cover 22 to the cushion 8 such as adhesives, may also be used.
- trim cover fastener 22 is described as securing the trim cover seam 14 to the cushion 8 , the present invention is not limited to one trim cover fastener 22 .
- a plurality of trim cover fasteners 22 may be used to secure the trim cover seam 14 to the cushion 8 .
- trim cover fastener 22 may be relatively easily detached from the cushion 8 . Because the trim cover fastener 22 is typically made from a thermoplastic polymer, it may be easily cut. This allows for relatively easy removal of the trim cover 12 to allow for reupholstering. Another advantage is the relatively low cost of manufacturing and materials typically used for the present invention. Also, although the trim cover fastener 22 may be relatively easily removed, it still provides a relatively strong attachment.
Abstract
In at least one embodiment, the present invention relates to a seat component comprising a cushion, a trim cover having at least one seam, and a trim cover fastener for attaching the trim cover seam to the cushion. The trim cover fastener has a first end attached to the trim cover seam and a second end extending into at least a portion of, and attached to, the cushion.
Description
- 1. Field of the Invention
- The present invention relates to a seat component with a trim cover fastener for attaching a trim cover to a cushion.
- 2. Background Art
- Seat components typically include a trim cover, usually made of some type of flexible upholstery sheet such as fabric or synthetic leather, attached to a cushion. The cushion used for occupant seating is usually constructed with at least one trench or groove, and more typically with several trenches or grooves on its upper surface. Two ends of upholstery sheet are typically connected to each other to form a seam. Sewing the two ends of upholstery sheet together, or some other suitable attaching means typically holds the seam together. Typically, the seam fits into the trenches of the cushion and is attached such that the upholstery sheet is generally fixed in position.
- Some current methods for attaching the seam to the cushion involve the use of hog rings. In those methods, the seam is typically attached to a series of hog rings, which are then attached to a metal wire that runs through the cushion generally parallel to the upper surface of the cushion. This process may be difficult to use because it requires inserting the wire through the cushion in order to provide the support needed for the hog rings. In addition, the process used for attaching the hog ring to the support wire may be cumbersome, and the materials used may be expensive compared to other alternatives.
- Another method involves hooks and loops such as attaching a male strip of Velcro® to the seam, and attaching a female strip of Velcro® within the trenches in the cushion. The seam can then be secured within the trench by the Velcro® strip. A potential problem with this method is that because of the inherent readily releasable nature of Velcro®, the seam may become unintentionally detached from the cushion. Maintaining proper alignment of the seam may also be difficult when using Velcro®.
- Yet another method involves using some form of adhesive to attach the upholstery sheet seam to the cushion within the trenches. But this technique can pose a relatively significant problem if the seat component needs to be reupholstered, as adhesives are intended to be permanent attachments. Maintaining proper alignment of the seam may be difficult with adhesives as well.
- It would be desirable to develop a seat component with a trim cover fastener that is relatively easy to use, that provides a relatively secure manner of attaching a trim cover seam to a cushion, and that could be detached relatively easily to allow for reupholstering.
- In at least one embodiment, the present invention provides a seat component comprising a cushion, a trim cover having at least one seam, and a unitary trim cover fastener for attaching the trim cover seam to the cushion. The trim cover fastener has a first end attached to the trim cover seam and a second end extending into at least a portion of, and attached to, the cushion.
- In at least another embodiment, the present invention further provides a method for securing a trim cover to a cushion. The method comprises securing a first end of a unitary trim cover fastener to a trim cover, inserting a second end of the trim cover fastener into at least a portion of the cushion and securing the second end of the trim cover fastener to the cushion.
- In at least another embodiment, the present invention further provides a seat component comprising a cushion having a first side spaced from a second side, a trim cover having at least one seam, and a plastic trim cover fastener for attaching the trim cover seam to the cushion. The trim cover fastener has a first end attached to the trim cover seam adjacent the first side of the cushion and a second end adjacent and secured to the second side of the cushion.
- The above features, and other features and advantages of the present invention are readily apparent from the following detailed descriptions thereof when taken in connection with the accompanying drawings.

However, it is to be understood that the disclosed embodiments are merely exemplary of the invention that may be embodied in various and alternative forms. The Figures are not necessarily to scale, some features may be exaggerated or minimized to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for the claims and/or as a representative basis for teaching one skilled in the art to variously employ the present invention.
- Referring to
FIGS. 1 and 3 , avehicle seat 10 typically comprises a seat bottom, a backrest, and a head rest. The seat bottom comprises acushion 8 covered by atrim cover 12 having at least oneseam 14. The seat back and the head rest also typically comprise a cushion covered by a trim cover having at least on seam. Thecushion 8 typically includes at least afirst side 18 and asecond side 20, opposite the first side. Thefirst side 18 of thecushion 8 typically defines at least onetrench 16, with at least a portion of thetrim cover seam 14 being held in thetrench 16. AlthoughFIG. 1 shows the front seat of a vehicle, it should be understood that the present invention can be used with any cushion component of any seating assembly, such as rear vehicle seats. -
FIG. 2 shows an embodiment of atrim cover fastener 22 having afirst end 24 and asecond end 26, with aconnector portion 28 extending between and connecting the first 24 and second ends 26. Thesecond end 26 of thetrim cover fastener 22, while being compressible, is shown in an expanded state inFIG. 2 . Thetrim cover fastener 22 attaches thetrim cover 12 to thecushion 8. AlthoughFIG. 2 shows thefastener 22 attaching the seat bottom trimcover 12 to theseat bottom cushion 8, it should be understood that thefastener 22 of the present invention can be used to attach any trim cover to any cushion, such as a seat back cover to a seat back cushion. - While the
trim cover fastener 22 may be made of any suitable material, in at least one embodiment, thetrim cover fastener 22 is made of thermoplastic polymer. In at least one embodiment, thefastener 22 should be sufficiently configured and made of suitable material to withstand 1-100 pounds of tensile force, as measured by ASTM Test Method No. ASTM D638. In at least another embodiment, thefastener 22 should be sufficiently configured and made of suitable material to withstand 5-50 pounds of tensile force, as measured by ASTM Test Method No. ASTM D638. In at least another embodiment, thefastener 22 should be sufficiently configured and made of suitable material to withstand 10-25 pounds of tensile force, as measured by ASTM Test Method No. ASTM D638. The use of thermoplastic polymer for thetrim cover fastener 22 is suitable because it enables thesecond end 26 to be compressible. As will be explained below, a compressiblesecond end 26 facilitates attaching thetrim cover 12 to thecushion 8. - Relatively low cost is also a beneficial property associated with thermoplastic polymers. In addition, the flexibility of thermoplastic polymers can provide greater comfort benefits, as the
trim cover fasteners 22 will be relatively unfelt by a seat occupant. In at least one embodiment flexible plastic polypropylene or polyethylene is preferred. It is also important to note that different portions of thetrim cover fastener 22 may be made from different materials. While thetrim cover 12 may be made of any suitable material, in at least certain embodiments thetrim cover 12 is made of a fabric or synthetic leather cover suitable for seating in a motor-vehicle. Thecushion 8 may have any suitable configuration and may be made of any suitable material, such as molded polymeric material like polyurethane foam. - Referring again to
FIG. 3 , a sectional side view of an embodiment of thetrim cover fastener 22 is shown securing thetrim cover seam 14, and thus thetrim cover 12, to thecushion 8. In this embodiment, thefirst end 24 of thetrim cover fastener 22 is attached to thetrim cover seam 14. As shown in the embodiment illustrated inFIG. 3 , thetrim cover 12 and thetrim cover seam 14 are adjacent to thefirst side 18 of thecushion 8. In this embodiment, thesecond end 26 of thetrim cover fastener 22 is adjacent to and secured to thesecond side 20 of thecushion 8. In the embodiment shown inFIG. 3 , a hole 38 extends through thecushion 8 between the first 18 and second 20 sides. - The
connector portion 28, which in this embodiment extends through the hole 38 in thecushion 8, extends between and connects the first 24 and second 26 ends of thetrim cover fastener 22. As shown inFIG. 3 , thetrim cover seam 14 is attached to thefirst end 24 of thetrim cover fastener 22 such that thetrim cover seam 14 is held adjacent afirst side 18 of thecushion 8. In at least another embodiment, thetrim cover 12 does not have to be directly adjacent thecushion 8, as other materials or fabrics may be placed between thetrim cover 12 and thecushion 8. Typically, thefirst end 24 of thetrim cover fastener 22 is secured adjacent thefirst side 18 of thecushion 8 at a position located at or near the vertex of thecushion trench 16. It is also important to note that althoughFIG. 3 shows thefirst end 24 of thetrim cover fastener 22 attached below thetrim cover seam 14, thefirst end 24 of thetrim cover fastener 22 may also be attached above thetrim cover seam 14, such that theconnector portion 28 has a portion that extends above thetrim cover seam 14. For instance, in certain embodiments, thefirst end 24 of thetrim cover fastener 22 could be on the outer surface of thetrim cover 12. - The
trim cover fastener 22 can be secured to thetrim cover 12 and thecushion 8 in any suitable manner. One suitable manner is to attach thefirst end 24 of thetrim cover fastener 22 to thetrim cover seam 14 and then attach thesecond end 26 of thetrim cover fastener 22 to thesecond side 18 of thecushion 8, as shown inFIG. 3 . One way of inserting thesecond end 26 of thetrim cover fastener 22 into at least a portion of thecushion 8 involves using a cut-through needle. In this embodiment, thesecond end 26 of thetrim cover fastener 22 is compressed into a scrolled state.FIGS. 6B and 6C show thetrim cover fastener 22 with thesecond end 26 in a scrolled state in greater detail. Thesecond end 26 of thetrim cover fastener 22 is then loaded into a cut-through needle. In at least one embodiment, the cut-through needle, loaded with thesecond end 26 of thetrim cover fastener 22, is inserted all the way through thecushion 8. This can create the hole 38 through thecushion 8 that extends between the first 18 and second 20 sides, as shown inFIG. 3 . When inserting the cut-through needle through the cushion, thesecond end 26 of thetrim cover fastener 22 is typically in a position such that thelongest dimension 36 of thesecond end 26 is the dimension in the direction ofmotion 44 of the cut-through needle, as shown inFIG. 6C . Thesecond end 26 of thetrim cover fastener 22 is typically released from the cut-through needle at thesecond side 20 of thecushion 8. In this embodiment, the cut-through needle retracts back through thecushion 8, leaving thesecond end 26 of thetrim cover fastener 22 adjacent thesecond side 20 of thecushion 8. In at least this embodiment, thesecond end 26 of thetrim cover fastener 22 rotates 90 degrees such that thelongest dimension 36 is positioned parallel to thesecond surface 20 of thecushion 8, as shown inFIG. 6B . Finally, thesecond end 26 of thetrim cover fastener 22 typically expands such that it is in the expanded state shown inFIG. 6A . This process may then be repeated using one or more othertrim cover fasteners 22 to secure one or more other parts of thetrim cover seam 14 to thecushion 8 near the vertex of atrench 16. - In another embodiment illustrated in
FIGS. 4A and 4B , thetrim cover seam 14 may be attached to a tie-down portion 30. In this embodiment afirst end 32 of the tie-down portion 30 is attached to thetrim cover seam 14 and a second end 34 is attached to thefirst end 24 of thetrim cover fastener 22. Thetrim cover seam 14 may be sewn to thefirst end 32 of the tie-down portion 30, or any other suitable attaching means may be used. - Referring to
FIGS. 4A and 4B , the tie-down portion 30 and the attachedtrim cover seam 14 may be positioned in thecushion trench 16. In at least this embodiment, thefirst end 24 of thetrim cover fastener 22 is attached to the second end 34 of the tie-down portion 30. Thefirst end 24 of thetrim cover fastener 22 is typically secured adjacent thefirst side 18 of thecushion 8. Thesecond end 26 of thetrim cover fastener 22 is then typically inserted into at least a portion of thecushion 8 and is secured to thecushion 8, such as at thesecond side 20 of thecushion 8. - Using the tie-down portion 30 helps keep the
trim cover seam 14 together, which allows thetrim cover fasteners 22 attaching thetrim cover seam 14 to thecushion 8 to be spaced farther apart from each other. It also helps protect the upholstery material from being damaged during the attachment process, since only the tie-down portion 30 will be directly attached to thecushion 8. In addition, when removing thetrim cover fasteners 22 for reupholstering purposes, thetrim cover seam 14 remains intact if a tie-down portion 30 is used. The tie-down portion 30 will also help create an even seam and maintain proper alignment. Because thetrim cover 12 is typically made of some type of fabric, thetrim cover seam 14 may not be able to withstand pointed forces. Sewing a tie-down portion 30 along thetrim cover seam 14 will help distribute the pointed forces associated with the attachment to the trim cover faster 22, along the length of thetrim cover seam 14. And because the tie-down portion 30 is typically reinforced along the edge with a thermoplastic polymer, it will be able to withstand relatively greater pointed forces than thetrim cover seam 14 alone. - Referring to
FIGS. 3 and 6 A, thefirst end 24 andsecond end 26 of thetrim cover fastener 22 are adjacent the first 18 and second 20 sides, respectively, of thecushion 8. Theconnector portion 28 typically extends through thecushion 8 between thefirst side 18 and thesecond side 20. Thecushion 8 may have a hole 38 on at least thesecond side 20 of thecushion 8 having two dimensions. Typically, at least one dimension of thesecond end 26 of thetrim cover fastener 22 is longer than at least one dimension of the hole 38. In at least the embodiments shown inFIGS. 2 and 6 A, thefirst end 24 of thetrim cover fastener 22 is in the shape of a solid cylinder. In the embodiments shown inFIGS. 2 and 6 A, thesecond end 26 of thetrim cover fastener 22 is in the shape of a hollow half-pipe. However, thetrim cover fastener 22 described in the present invention may have portions, such as the first and second ends 24 and 26, of any suitable shape and/or size. - In other embodiments, the
second end 26 of thetrim cover fastener 22 may be released within thecushion 8 before reaching thesecond side 20 of thecushion 8. In at least one embodiment, using the method involving the cut-through needle described above, the cut-through needle does not extend to thesecond side 20 of thecushion 8. Referring toFIGS. 5A and 5B , thetrim cover fastener 22 of the present invention is shown with thesecond end 26 extending into only a portion of, and attached to, thecushion 8 between thesides - To make the attachment shown in
FIGS. 5A and 5B relatively convenient to perform, thesecond end 26 of thetrim cover fastener 22 may be made of a material that can be compressible, as mentioned above. This allows thesecond end 26 of thetrim cover fastener 22 to be compressed into a scrolled state, as further shown inFIG. 6B . Compressing thesecond end 26 of thetrim cover fastener 22 decreases the surface area of thesecond end 26 so that it may more easily be inserted into thecushion 8. Referring toFIGS. 5B and 6A , thesecond end 26 of thetrim cover fastener 22 has at least onedimension 36 longer than at least one dimension of the hole 38. In this embodiment, thesecond end 26 of thetrim cover fastener 22 may be attached to thecushion 8. This attachment can typically be achieved by orienting thesecond end 26 of thetrim cover fastener 22 in such a way that it is prevented from moving through the hole 38 towards thefirst side 18 of thecushion 8. One approach is to provide aslot 40, which thesecond end 26 of thetrim cover fastener 22 fits into, as shown inFIG. 5C . Another approach is to provide thesecond end 26 of thetrim cover fastener 22 withcompressible fins 42 that can extend intoslots 40, as shown inFIG. 5D . Thefins 42 are compressed during the insertion process, but can expand into theslots 40 when thesecond end 26 of thetrim cover fastener 22 is in the appropriate position. Other appropriate means for attaching thesecond end 26 of thetrim cover 22 to thecushion 8, such as adhesives, may also be used. - It is important to note that although only one
trim cover fastener 22 is described as securing thetrim cover seam 14 to thecushion 8, the present invention is not limited to onetrim cover fastener 22. A plurality oftrim cover fasteners 22 may be used to secure thetrim cover seam 14 to thecushion 8. - One advantage of the present invention is that the
trim cover fastener 22 may be relatively easily detached from thecushion 8. Because thetrim cover fastener 22 is typically made from a thermoplastic polymer, it may be easily cut. This allows for relatively easy removal of thetrim cover 12 to allow for reupholstering. Another advantage is the relatively low cost of manufacturing and materials typically used for the present invention. Also, although thetrim cover fastener 22 may be relatively easily removed, it still provides a relatively strong attachment. - While embodiments of the invention have been illustrated and described, it is not intended that these embodiments illustrate and describe all possible forms of the invention. Rather, the words used in the specification are words of description rather than limitation, and it is understood that various changes may be made without departing from the spirit and scope of the invention.
