Referring to the embodiment generally illustrated in FIGS. 1-22, reference numeral 10 generally designates a vehicle seating assembly including a seatback 12 having a back panel 14 with a front closeout panel 16. A carrier 18 is supported inside the seatback 12 and includes an upper thoracic region 20 having a peripheral support 22. A peripheral gap 24 is defined between the front closeout panel 16 and the upper thoracic region 20. A bottom portion 26 of the upper thoracic region 20 includes a lower wall 28 having a sinusoidal configuration. The vehicle seating assembly 10 also includes a lower lumber region 32 having a peripheral support 34. A peripheral gap 36 is defined between the front closeout panel 16 and the lower lumber region 32. An upper portion 38 of the lower lumbar region 32 includes an upper wall 40 having a sinusoidal configuration. A plurality of concave connectors 42 couple the lower wall 28 of the upper thoracic region 20 with the upper wall 40 of the lower lumber region 32.
With reference to FIGS. 1 and 2, the vehicle seating assembly 10 is generally configured for use inside a vehicle 50 and includes a seat 52 defining a seating surface 51 in addition to the seatback 12 defining a seatback surface 53. Both the seat 52 and the seatback 12 include a cushion assembly 54, 55, respectively, disposed thereon. It is generally contemplated that the vehicle 50 may include an automobile, such as a car, a truck, or a van, and that the vehicle seating assembly 10 will be adjustable within the vehicle 50. The cushion assembly 54 is coupled with a seat frame 56, while the cushion assembly 55 is supported on a seatback frame 57. The vehicle seating assembly 10 is positioned on a slide assembly 60, including a rail 62 and a slide 64. The rail 62 is generally fastened to a floor 66 of the vehicle 50 and the slide 64 is fastened to the vehicle seating assembly 10. The rail 62 and the slide 64 are slidably adjustable relative to one another, such that the vehicle seating assembly 10 is adjustable fore and aft within the vehicle 50. The vehicle seating assembly 10 also includes a variety of other adjustability functions, including adjustability of the seatback 12, which may include upper thoracic and lumbar support, as well as reclining functions. The seat 52 is also adjustable and includes thigh and leg adjustability.
With reference to FIGS. 2-6, in the illustrated embodiment, the carrier 18 for the seatback 12 is configured to support the weight of a passenger applying pressure to the cushion assembly 55 disposed on the seatback 12. Accordingly, the carrier 18 generally creates an interface between the cushion assembly 55 and the structural components of the seatback 12. The carrier 18 includes a variety of connection points for coupling with the cushion assembly 55, a coverstock 74, and directly to the seatback frame 57. The carrier 18 is generally defined by the upper thoracic region 20 and the lower lumbar region 32. The concave connectors 42 couple the lower wall 28 of the upper thoracic region 20 with the upper wall 40 of the lower lumbar region 32. The upper thoracic region 20 generally defines an interior cavity 80 within which a fan support 82 is positioned. Similarly, the lower lumbar region 32 also defines a central space 84 that may include climate comfort features, lumbar support features, etc.
With reference to FIGS. 2-4 and 6-9, the carrier 18 includes an upper scalloped portion 90 configured to accommodate a head restraint 92 disposed on a top portion 94 of the seatback 12. In addition, the carrier 18 includes a plurality of coverstock detents 96 disposed about a peripheral edge 98 of the carrier 18. The coverstock detents 96 are configured to receive fasteners disposed about a periphery 100 of the coverstock 74. The fasteners are designed to engage directly with the peripheral edge 98 of the carrier 18, thereby supporting the coverstock 74 and the cushion assembly 55 on the carrier 18. In addition, the upper thoracic region 20 of the carrier 18 includes snap-fit connection apertures 110 designed to receive snap-fit connectors disposed on a forward side of an articulating upper thoracic support of the seatback 12. A plurality of coverstock securing members 120 are located adjacent to an intermediate space 122 defined in the upper thoracic region 20. The coverstock securing members 120 are spaced a predetermined distance and designed to engage intermediate fasteners on a backside of the coverstock 74. In addition, a variety of spacing apertures 124 are disposed between each of the coverstock securing member 120.
With reference again to FIGS. 2-4 and 6-9, the fan support 82 are operably coupled with the lower wall 28 of the upper thoracic region 20 and also coupled with first and second angled supports 130, 132. Each of the first and second angled supports 130, 132 extends into the intermediate space 122 of the upper thoracic region 20 and each includes an undulating or sinusoidal configuration. This construction allows for flexibility and movement of the fan support 82 to accommodate the different weights of users and also different postures and loads that can affect the seatback 12. As previously noted, the bottom portion of the upper thoracic region 20 includes the lower wall 28, which has an undulating or sinusoidal configuration. Notably, the undulating or sinusoidal configuration of the lower wall 28 of the upper thoracic region 20 undulates in a plane generally parallel with a seating surface of the seat 52. Accordingly, the undulations extend forward and rearward relative to the seatback surface. The upper portion of the lower lumbar region 32, and more specifically, the upper wall 40 of the lower lumbar region 32 includes a sinusoidal configuration as well. The sinusoidal configuration of the upper wall 40 of the lower lumbar region 32 also undulates forward and rearward relative to the seatback 12. It will be understood that the carrier 18 is generally curved to complement the shape of the back of an occupant. More specifically, the upper thoracic region 20 is shaped to generally cradle and support the upper back of an occupant, while the lower lumbar region 32 is designed to cradle and support the lower back of an occupant.
With reference now to FIG. 5, in the illustrated embodiment, the seatback 12 of the vehicle seating assembly 10 includes the following components. The seat frame 56 is connected with the seat 52 and provides general structural support to the occupant. The back panel 14 is connected with a rear portion of the seatback frame 57. The head restraint 92 is disposed above the seatback frame 57 and is operably coupled therewith. The head restraint 92 may include a variety of functions, including forward and rearward motion, as well as upward and downward motion, to better support the head of an occupant. In addition, the vehicle seating assembly 10 includes an upper thoracic support 116 that is adjustable between forward and rearward positions. The upper thoracic support 116 is located in front of the front closeout panel 16. The front closeout panel 16 includes an upper portion 156 and a lower portion 158. The upper portion 156 of the front closeout panel 16 wraps around a front portion of the seatback frame 57 and couples with the hard back panel 14. The lower portion 158 of the front closeout panel 16 engages with a lower portion of the seatback frame 57 and engages a lower portion of the hard back panel 14. The peripheral gap 24 is defined between the upper portion 156 of the thoracic support 116 and the front closeout panel 16. The peripheral gap 24 is also located between the lower lumbar region 32 and the lower portion 158 of the front closeout panel 16. First and second side support members 164, 166 are configured to be fastened with sides of the carrier 18. The entire carrier 18, as well as first and second side support members 164, 166, are designed to engage the upper portion 156 and the lower power 158 of the front closeout panel 16. At the same time, the carrier 18 supports the cushion assembly 55 and the coverstock 74. The cushion assembly 55 may be operably coupled with the coverstock 74 via a glue or adhesive, or via fasteners configured to engage the front of the cushion assembly 55, as previously disclosed.
With reference now to FIGS. 6-10, 15 and 16, the carrier 18 includes openings 170 on each side of the lower lumbar region 32. The openings 170 are designed to receive engagement features 172 on each of the first and second side support members 164, 166. In addition, a lower protuberance 174, which extends in a forward direction, is configured to engage an aperture 176 having peripheral slots 178. The aperture 176 is configured to receive the protuberance 174 and secure the same such that the first and second side support members 164, 166 can be retained on the carrier 18. In addition, a second lower protuberance is disposed below the protuberance 174, and is configured to engage a lower aperture 182 on the carrier 18. A lower opening 182 also includes peripheral slots 184. Each of the protuberances 174, 180 maintain the first and second side support members 164, 166 in secure abutment with the carrier 18. In addition, an upwardly turned hook 190 is disposed on an upper portion of each of the first and second side support members 164, 166. The upper hook securely engages an engagement wall 192 on a forward side of the carrier 18. It will be understood that the first and second side support members 164, 166 are mirror images of one another.
With reference now to FIGS. 12-14, various undulating or sinusoidal configurations of portions of the carrier 18 are illustrated. FIG. 12 illustrates an undulating or configuration that extends along the first and second angled supports 130, 132. The undulating configuration that extends along the first and second angled supports 130, 132 allows flexibility of the fan support 82 such that the fan support 82, or a fan disposed therein, does not provide for an uncomfortable projection into the back of a passenger. In addition, the first and second angled supports 130, 132, and the sinusoidal configuration of the first and second angled supports 130, 132, allow for flexible movement of the fan support 82 relative to the already flexible carrier 18. FIG. 13 illustrates the sinusoidal configuration across the lower wall 28 of the upper thoracic region 20. The sinusoidal configuration allows for flexible movement of the upper thoracic region 20 relative to the lower lumbar region 32. The lower wall 28 of the upper thoracic region 20 is operably coupled with the upper wall 40 of the lower lumbar region 32 via the concave connectors 42. Accordingly, flexibility in both lateral and vertical directions is provided. For even additional flexibility, the sinusoidal configuration is provided in the upper wall 40 of the lower lumbar region 32, as shown in FIG. 14. It will also be noted that a periphery of the upper thoracic region 20 and lower lumbar region 32 includes a rearwardly opening slot configured to receive trim stock fasteners that secure a trim stock to a rear portion of the carrier 18.
With reference to FIGS. 17 and 18, the illustrated embodiment shows the configuration of the protuberances 174, 180 relative to the apertures 176, 182, respectively. As illustrated, an inner wall 194 that defines the apertures 176, 180 is canted or angled on a side of the apertures 176, 182 to provide an easier snap fit connection with the protuberances 174, 180. This construction has the added benefit of maintaining a more secure connection between the protuberances 174, 180 and the apertures 176, 182. The cant or angled wall portion is specifically sized and fitted to retain the protuberances 176, 180 during use.
With reference now to FIGS. 8-12, as well as FIGS. 19 and 20, a lower cross-member 200 of the carrier 18 includes lateral elongate slots 202. The elongate slots 202 are configured to receive engagement features in the form of retention tethers 204 that include a securing member 206 and a flexible band 208 connected to the securing member 206. The flexible band 208 may be secured with the cushion assembly 55 or the coverstock 74 and may be elastic in nature, allowing for expansion and contraction. The retention tethers 204 provide a releasable yet reliable engagement of the cushion assembly 55 with the carrier 18 (FIGS. 19 and 20).
With reference now to FIGS. 21 and 22, upper corners 230 of the carrier 18, and more specifically of the upper thoracic region 20 of the carrier 18, include a generally planar portion with a fastener receiving aperture 234. The fastener receiving aperture 234 includes slots configured to accommodate a mechanical fastener engaging the fastener receiving aperture 234. The fastener receiving aperture 234 includes a generally semicircular construction with slots 236 extending therefrom. In the illustrated embodiment, the slots 236 extend approximately 120 degrees from one another. However, it will be understood that the slots 236 may extend at any angle relative to one another, and may be more than or less than three slots 236 that extend from the fastener receiving aperture 234.
With reference now to FIGS. 23-25, the vehicle seating assembly 10 of the cushion assembly 55 is supported by the carrier 18. The lower cross-member 200 of the carrier 18 generally defines a frame receiving cavity 250. A first set 252 of ribs 254 extend across the frame receiving cavity 250 in a direction perpendicular to a longitudinal extent of the lower cross-member 200. The first set 252 of ribs 254 extend between the lower cross-member 200 and a lower brace 256 of the seatback frame 57. A second set 258 of ribs 254 are parallel with the first set 252 of ribs 254. The second set 258 of ribs 254 are longer than the first set 252 of ribs 254.
With reference again to FIGS. 6-8, the lower cross-member 200 generally defines an integrated decking arm support feature that is configured to handle 1.5 times the overall seat mass of the vehicle seating assembly 10. The ribs 254 of the lower cross-member 200 provide structural rigidity to the lower cross-member 200. During assembly, the carrier 18, and specifically the integrated decking arm feature of the lower cross-member 200, withstands a substantial load to allow the seating assembly 10 to be decked in the vehicle 50 using existing vehicle assembly decking arm technologies. This design is integrated into the lower area of the carrier 18, where the lower cross-member 200 nests or abuts the steel cross-member of the seatback frame 57. More specifically, the plurality of ribs 254, which are disclosed in further detail herein, nest against the lower brace 256, typically made of steel, are configured for compressive loading, while maintaining a robust cross-section to resist crushing and/or deformation to the carrier 18 while the seating assembly 10 is being positioned inside the vehicle 50.
With reference again to FIGS. 6-8, as well as FIG. 20, the lower cross-member 200 includes a double flange construction 260, including an upper flange 262 and a lower flange 264 to provide additional rigidity to the lower cross-member 200. The upper flange 262 generally defines a lateral wall that is integral with a forward vertical wall 266. This construction provides additional rigidity to the lower cross-member 200. A plurality of transverse ribs 270 are disposed proximate each of the elongate slots 202. In the illustrated embodiment, a top rib 272 is disposed above the elongate slot 202, an intermediate rib 274 is disposed adjacent to the elongate slot 202, and a lower rib 276 is disposed below the elongate slot 202. It will be understood that the features, as illustrated in FIG. 20, which illustrate a rear left side of the lower cross-member 200 of the carrier 18, will be similarly arranged on the rear right side of the seatback carrier 18 in a mirror like construction. Notably, coverstock detents 96 are defined in the double flange construction 260 of the lower cross-member 200. More specifically, the coverstock detents 96 are defined between the upper flange 262 and the lower flange 264 of the double flange construction 260.
With reference again to FIGS. 6-8, 20, and 23-25, the rib features include three sets of ribs (254 (FIG. 7) having slightly varying constructions. Specifically, the first set 252 of ribs 254 are inner ribs that extend from a rear edge of the upper flange 262 forward and into contact with the vertical wall 266 of the lower cross-member 200. The second set 258 of ribs 254, an intermediate set of ribs, extends from a rearmost edge of the upper flange 262 of the lower cross-member 200 forward and upward to a position proximate a top edge 278 of the vertical wall 266 of the lower cross-member 200. A third set 280, an outermost set of ribs 254, extends from an intermediate area of the upper flange 262 of the lower cross-member 200 to the intersection of the upper flange 262 and the vertical wall 266, and up the vertical wall 266 to an intermediate area of the vertical wall 266 before terminating. Each set of ribs 254 includes different configurations to aid in the overall strength, yet lightweight, properties of the lower cross-member 200, and consequently the carrier 18. In addition, the lower cross-member 200 is generally constructed from a polymeric material, as are the vertically-oriented ribs 254. Additionally, the vertically-oriented ribs 254 define a space 290 between the lower cross-member 200 and the lower brace of the seatback frame 57. As previously noted, the vertically-oriented ribs 254 are generally configured to take on compressive loads, but maintain spacing between the lower cross-member 200 and the lower brace 256 of the seatback frame 57. The lower cross-member 200 generally defines a lower boundary of a climate control opening. Thus, the lower cross-member 200 defines the lower edge of the central space 84, which is configured to accommodate climate control features, lumbar support features etc., of the vehicle seating assembly 10.
