DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0035] Referring now to the drawings, there is illustrated in
[0036] A layer 105, such as a preferably flexible finish trim layer for the vehicle seat 100, covers at least portions of the surfaces of the seat bottom 102, the seat back 103, and the headrest 104 upon which an occupant (not shown) of the vehicle seat 100 sits or otherwise contacts. As non-limiting examples, the finish trim layer 105 may be vinyl, cloth, natural leather, or synthetic leather material.
[0037] As shown in
[0038]
[0039] Either or both of the first and third circuit portions 112 and 114, respectively, may be embodied as conventional metallic electrical conductors, such as wires, that are supported by the supporting structure 106 of the vehicle seat 100. When the electrical conductors of the first and third circuit portions 112 and 114, respectively, are separate from and/or readily removable from the supporting structure 106, the electrical conductors are not considered part of the supporting structure 106. Alternatively, either or both of first and third circuit portions 112 and 114, respectively, may be directly incorporated into the supporting structure 106 and, as such, are not readily removable from the supporting structure 106. As non-limiting examples, either or both of the first and third circuit portion 112 and 114, respectively, may be incorporated into the frame member 107 when the frame member 107 is fabricated from an electrically conductive material, such as steel or aluminum (i.e., the frame member 107 itself is the electrical conductor) or the foam bun 108 when the foam bun 108 is fabricated from an electrically conductive foam material.
[0040] The second circuit portion 113 is incorporated or otherwise integrated into the finish trim layer 105 such that the second circuit portion 113 may not be readily removed or otherwise separated from the finish trim layer 105. The second circuit portion 113 is incorporated into the finish trim layer 105 such that any removal of the second circuit portion 113 from the finish trim layer 105 would typically damage or otherwise render the finish trim layer 105 unsuitable for use with the vehicle seat 100. The second circuit portion 113 is formed from an electrically conductive trim material. The electrically conductive trim material may be an entirety of the finish trim layer 105 or may be less than the entirety of the finish trim layer 105.
[0041] As non-limiting examples, the finish trim layer 105 at the second circuit portion 113 may be formed from an electrically conductive smart material (as the term electrically conductive smart material is known to those skilled in the art) or a piezoelectric material. Such electrically conductive finish trim materials are commercially available from, for example, Noble Conductive Foams, Gilford Conductive Textiles, EO Conductive Leathers, and Xonano Piezo-Foams. Alternatively, as a further non-limiting example, the finish trim layer 105 at the second circuit portion 113 may be a non-electrically conductive finish trim material to which electrical conductivity has been added. As non-limiting examples, electrical conductivity may be added by weaving an electrically conductive thread into known fabric material or by applying electrically conductive ink to known leather material. Such electrically conductive ink is commercially available from, for example, Bare Ink.
[0042]
[0043] The mechanical connection provided by each of the first and second connector assemblies 115 and 116, respectively, is between the finish trim layer 105 and the supporting structure 106. The mechanical connection retains the finish trim layer 105 on the supporting structure 106 (e.g., the frame member 107 and/or the foam bun 108) and resists or otherwise prevents separation, disassembly, or other uninstallation of the finish trim layer 105 from the supporting structure 106.
[0044] The electrical connection provided by each of the first and second connector assemblies 115 and 116, respectively, completes the electrical circuit 109. The first connector assembly 115 provides a first electrical connection and completes the electrical circuit 109 between the first and second circuit portions 112 and 113, respectively. The second connector assembly 116 provides a second electrical connection and completes the electrical circuit 109 between the second and third circuit portions 113 and 114, respectively. Furthermore, either of the first or second connector assemblies 115 or 116, respectively, may be used unaltered to provide the mechanical connection only, such as when the electrical circuit 109 is omitted from the vehicle seat 100.
[0045] As illustrated, the first connector assembly 115 provides the mechanical connection between the finish trim layer 105 and the frame member 107 and the second connector assembly 116 provides the mechanical connection between the finish trim layer 105 and the foam bun 108. Alternatively, the first connector assembly 115 may provide the mechanical connection between the finish trim layer 105 and the foam bun 108 and the second connector assembly may provide the mechanical connection between the finish trim layer 105 and the frame member 107.
[0046]
[0047] The first connector assembly 115 is selectively operable between an engaged state and a disengaged state. In the engaged state of the first connector assembly 115, the arrow connector 117 and the receiver clip connector 118 are engaged together to provide the mechanical connection to retain the finish trim layer 105 on the supporting structure 106 and the electrical connection to complete the electrical circuit 109. In the disengaged state, the arrow connector 117 and the receiver clip connector 118 are separated such that the trim and electrical connections are not provided, the finish trim layer 105 is not retained on the supporting structure 106, and the electrical circuit 109 is not completed. The engaged and disengaged states will be discussed further with reference to
[0048] Referring specifically to
[0049] The arrow connector 117 is fixed to the finish trim layer 105. As illustrated in
[0050] In
[0051] The mechanical and electrical connections between the body member 119 and the finish trim layer 105 are made by the electrically conductive thread. As illustrated, the electrically conductive thread fixes the body member 119 and the finish trim layer 105 together with a gap or other separation between the body member 119 and the finish trim layer 105. Alternatively, the electrically conductive thread may fix the body member 119 and the finish trim layer 105 together by drawing the body member 119 and the finish trim layer 105 together such that there is no gap between the body member 119 and the finish trim layer 105 and the first and second insulation layers 122 and 123, respectively, contact each other.
[0052] In
[0053] The non-electrically conductive thread provides the mechanical connection between the finish trim layer 105 and the body member 119 and the direct, electrical contact between the first and second uninsulated portions 126 and 127, respectively, provides the electrical connection between the finish trim layer 105 and the body member 119. Alternatively, the conductive thread of

[0057] Also in the engaged state, when the barb 120 is inside the cavity 129, second contact surfaces 133 are defined between the barb 120 and the electrically conductive body member 119. The second contact surfaces 133 provide the electrical connection for the first connector assembly 115. The electrical connection at the second contact surfaces 133 completes the electrical circuit 109 (shown in
[0058] The second contact surfaces 133 also provide additional mechanical connections for the first connector assembly 115. As a non-limiting example, the second contact surfaces 133 resist separation of the finish trim layer 105 from the supporting structure 106 in at least one direction perpendicular to each of the second contact surfaces 133 (e.g., in a generally vertical direction as the first connector assembly 115 is illustrated in
[0059] As discussed, in

[0068] The second connector assembly 116 has first and second connectors 141 and 142, respectively. Each of the first and second connectors 141 and 142, respectively, is adapted as what is known to those skilled in the art as a j-retainer. The first j-retainer connector 141 has a first curved section 143 and a first hooked end 144. The second j-retainer connector 142 has a second curved section 145 and a second hooked end 146. The first and second hooked ends 144 and 146, respectively, have corresponding shapes. In the engaged state, shown in
[0069] The contact surface 147 resists separation of the first and second j-retainer connectors 141 and 142, respectively. As a non-limiting example, the contact surface 147 resists separation of the first and second j-retainer connectors 141 and 142, respectively, in at least one direction perpendicular to the contact surface 147. As a result, the contact surface 147 provides the mechanical connection for the second connector assembly 116. When the second connector assembly 116 is in the engaged state (shown in

[0074]
[0075] A first portion, indicated generally at 456, of the fifth connector assembly 455 includes a plurality of electrically conductive first interlocking teeth and a second portion, indicated generally at 457, of the fifth connector assembly includes a plurality of electrically conductive second interlocking teeth. The first and second teeth 456 and 457, respectively, are selectively engaged or disengaged by a manually operated pull 458. The fifth connector assembly 455 is of a style commonly known as a zipper. Interlocking of the first and second teeth 456 and 457, respectively, provides a mechanical connection for the fifth connector assembly 455 at contact surfaces 459 between the first and second teeth 456 and 457, respectively.
[0076] The first and second teeth 456 and 457, respectively, are fabricated from an electrically conductive material. All, or less than all, of the first and second teeth 456 and 457, respectively, may be fabricated from the electrically conductive material. Alternatively, electrical conductivity may be added to a non-electrically conductive material (e.g., by using an electrically conductive ink, paint, or other finish). The contact surfaces 459 between the interlocking first and second teeth 456 and 457, respectively, provide an electrical connection for the fifth connector assembly 455.
[0077] Resistors 460 may be provided between the first teeth 456. The resistors 460 may indicate when the fifth connector assembly 455 is disengaged by reducing an electrical current flowing through the first teeth 456. When the fifth connector assembly 455 is engaged, the second teeth 457 allow the current to short circuit the resistors 460 and avoid the reduction in current. Alternatively, the resistors 460 may be provided between the second teeth 457.
[0078]
[0079] At least one first opening or other penetration 562 is provided in a finish trim layer 505. Each of the first openings 562 has a corresponding second opening or other penetration 563 in a supporting structure 506. An electrically conductive connecting ring 564, commonly referred to as a hog ring by those skilled in the art passes through each pair of the corresponding first and second openings 562 and 563, respectively. A first portion 565 of the ring 564 passes through the first openings 562 and a second portion 566 of the ring 564 passes through the second openings 563. The ring 564 provides the trim and electrical connections between the supporting structure 506 and a finish trim layer 505.
[0080] There are first contact surfaces 567 between the first ring portions 565 and the finish trim layer 505 and second contact surfaces 568 between the second ring portions 566 and the supporting structure 506. Each of the first and second contact surfaces 567 and 568, respectively, provides a mechanical connection and an electrical connection for the sixth connector assembly 561. Each of the first or second openings 562 or 563, respectively, may be dimensioned such that the first or second contact surface 567 or 568, respectively, is for a full circumference of the first or second opening 562 or 563, respectively. For example, the first or second opening 562 or 563, respectively, may have a diameter equal to the ring 564. Alternatively, each of the first or second openings 562 or 563, respectively, may be dimensioned such that the first or second contact surface 567 or 568, respectively, is for less than the full circumference of the first or second opening 562 or 563, respectively. This may occur when the first or second opening 562 or 563, respectively, has a diameter less than a diameter of the ring 564.
[0081]
[0082] An arrow connector, indicated generally at 617, is provided with at least one first opening or other penetration 662. Each of the first openings 662 has a corresponding second opening or other penetration 663 in a supporting structure 606. An electrically conductive connecting ring, indicated generally at 664 and commonly referred to as a hog ring by those skilled in the art, passes through each pair of the corresponding first and second openings 662 and 663, respectively. The ring 664 provides the trim and electrical connections between the supporting structure 606 and a finish trim layer 605. The first openings 662, second openings 663, ring 664, first ring portion 665, and second ring portion 666 correspond to the first openings 562, second openings 563, ring 564, first ring portion 565, and second ring portion 566 of

[0084] A first portion, indicated generally at 771, of the eighth connector assembly 770 includes a plurality of electrically conductive first hooks and a second portion, indicated generally at 772, of the eighth connector assembly 770 includes a plurality of electrically conductive loops. The hooks and loops 771 and 772, respectively, are selectively engaged or disengaged by pressing together or pulling apart the finish trim layer 705 and the supporting structure 706. The eighth connector assembly 770 is of a hook and loop fastener style commonly known, and commercially available, as Velcro. Interlocking of the hooks and loops 771 and 772, respectively, at contact surfaces (when the hooks and loops 771 and 772, respectively, are engaged) provides both a mechanical connection and an electrical connection for the eighth connector assembly 770.
[0085] In the described embodiments, a first portion of the connector assembly is fixed to the finish trim layer 105 and a second portion of the connector assembly is fixed to the supporting structure 106. Alternatively, for each of the embodiments, the first portion may be fixed to the supporting structure 106 and the second portion may be fixed to the finish trim layer 105.
