For purposes of description herein, the terms “upper,” “lower,” “right,” “left,” “rear,” “front,” “vertical,” “horizontal,” and derivatives thereof shall relate to the disclosure as oriented in FIG. 1. However, it is to be understood that the disclosure may assume various alternative orientations, except where expressly specified to the contrary. It is also to be understood that the specific devices and processes illustrated in the attached drawings, and described in the following specification are simply exemplary embodiments of the inventive concepts defined in the appended claims. Hence, specific dimensions and other physical characteristics relating to the embodiments disclosed herein are not to be considered as limiting, unless the claims expressly state otherwise.
In this document, relational terms, such as first and second, top and bottom, and the like, are used solely to distinguish one entity or action from another entity or action, without necessarily requiring or implying any actual such relationship or order between such entities or actions. The terms “comprises,” “comprising,” or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. An element proceeded by “comprises . . . a” does not, without more constraints, preclude the existence of additional identical elements in the process, method, article, or apparatus that comprises the element.
Referring to the embodiment generally illustrated in FIGS. 1-12, reference numeral 10 generally designates a seating assembly that includes a seat base 12. A seatback 14 is operably coupled to the seat base 12 and includes a seat cushion 16 disposed on a front side 18 thereof. A seatback panel 20 includes a protective panel 22 that is operably coupled therewith. The protective panel 22 includes an internal aluminum panel 24 and an external aluminum panel 26 disposed in the seatback 14 and is operably coupled therewith. A polymeric material 28 is disposed between the internal aluminum panel 24 and the external aluminum panel 26.
With reference now to FIGS. 1 and 2, the seating assembly 10 may be used in any vehicle, such as a car, a truck, a van, etc. It is also contemplated that the concept set forth in this disclosure may be utilized in a front or forward position of the vehicle as well as a rear or rearward position of the vehicle. The seating assembly 10, as illustrated, includes the seat base 12, which is positioned on rail slides 40 to allow fore and aft movement of the seating assembly 10 relative to the vehicle. A seat 42 is operably coupled with the seat base 12 and is movable relative thereto, as set forth in further detail below. In addition, the seatback 14 of the seating assembly 10 includes a lower lumbar region 44 and an upper thoracic region 46 as well as a head restraint 50. Each of the components of the seatback 14 may be configured for adjustability to properly support the size and weight of various occupants inside the vehicle.
With reference now to FIGS. 2 and 3, the seatback 14 is operably coupled with the seatback panel 20 by way of a variety of clips and hooks disposed on an interior surface 60 of the seatback panel 20. A peripheral piece 64 of the seatback panel 20 includes peripheral clips 62 that are configured to engage a front closeout panel 66 (FIG. 1) of the seating assembly 10. An upper portion 68 of the seatback panel 20 includes hooks 70 that are configured to engage a cross member of a frame of the seating assembly 10. A lower portion 72 of the seatback panel 20 includes clips 73 configured to engage a lower cross member of the frame of the seating assembly 10. A lower closeout panel 74 is disposed below the seatback panel 20 and includes a lower arced portion 75 that arcs inwardly under the seat 42 of the seating assembly 10. In the illustrated embodiment of FIGS. 2 and 3, the lower closeout panel 74 is heatstaked to a main body portion 76 of the seatback panel 20. The lower closeout panel 74 may include side support webs 77 that help support the lower arced portion 75 and conceal an interior of the seating assembly 10. The construction of the seatback panel 20 is generally configured to conceal an interior portion of the seatback 14 and also to provide protection to components disposed within the seatback 14. At the same time, there may be a desire for additional protection in seating assemblies that are used in conjunction with vehicles designed for law enforcement or military purposes. The seatback 14 and the seatback panel 20 are generally constructed from a polymeric material, but may also include cloth, leather, etc. In addition, the seatback panel 20 may include the lower closeout panel 74, the main body portion 76, and the peripheral piece 64 configured for engaging the front closeout panel 66 disposed on the seatback 14 of the seating assembly 10.
With reference now to FIG. 4, a cross-section of the seatback panel 20 of FIG. 3 is illustrated. As can be seen, the seatback panel 20 includes the protective panel 22, which is disposed in an intermediate portion of the seatback panel 20. The protective panel 22 is configured for attachment on the interior surface 60 of the seatback panel 20 and may be heatstaked, fastened, etc. to the interior surface 60 of the seatback panel 20. It is also contemplated that the protective panel 22 could be disposed on an exterior surface 80 of the seatback panel 20. As can be seen, the lower closeout panel 74 extends below the protective panel 22 near a foot well defined below the seat base 12 of the seating assembly 10.
With reference now to FIG. 5, which illustrates a cross-section taken at line V-V of FIG. 3, the protective panel 22 is illustrated in close proximity to the seatback panel 20. Sidewalls 90 of the seatback panel 20 extend forward, while the protective panel 22 is disposed in the intermediate portion of the seatback panel 20. On each side of the seatback panel 20, recesses 92 are configured to receive offsets 94 of the protective panel 22. Prior to securing the protective panel 22 with the interior surface 60 of the seatback panel 20, the interface of the offsets 94 with the recesses 92 may help to locate the protective panel 22 properly on the interior surface 60 of the seatback panel 20. In the illustrated embodiment, there are also a number of undulations 98 disposed at the intermediate portion of the seatback panel 20.
With reference now to FIGS. 6 and 7, the protective panel 22 includes a plurality of apertures 100 configured to receive fasteners, which may be heatstake bosses 102, that extend rearwardly from the interior surface 60 of the seatback panel 20. As previously noted, it will be understood that the connection of the protective panel 22 with the seatback panel 20 may be conducted in a variety of manners and is not limited to heatstaking. In addition, the protective panel 22 is configured to work in concert with the lower closeout panel 74 and is disposed above the lower closeout panel 74 after assembly.
As can be seen in FIG. 7, the protective panel 22 includes a three-dimensional shape that provides protection to the intermediate portion of the seatback 14. A central portion 110 of the protective panel 22 includes a slightly arcuate configuration (see FIG. 11) configured to abut or be adjacent to the undulations 98 of the seatback panel 20 (FIG. 5). In addition, the offsets 94, which include an angled portion 112 and a side portion 114, help increase the structural rigidity of the protective panel 22 as a whole. As previously noted, the offsets 94 help locate the central portion 110 proximate a central area of the seatback panel 20 before the protective panel 22 is secured with the interior surface 60 of the seatback panel 20. This central area is protected because when a user is seated on the seating assembly 10, the central area is positioned adjacent internal organs of the seated passenger. Not only does the protective panel 22 include a three-dimensional shape, the protective panel 22 also includes a tri-composite construction. This tri-composite construction includes the polymeric material 28 disposed between first and second aluminum layers 24, 26. The polymeric material 28 may be any of a variety of materials, including Kevlar™, glass, or fibers that may be woven or non-woven and intermixed through the polymeric material 28. Glass beads may be utilized to lighten the weight of a matrix of the polymeric material 28. The polymeric material 28 is disposed between the two layers constructed of the first and second aluminum layers 24, 26. The first and second aluminum layers 24, 26 may vary in thickness, but are generally contemplated to be approximately 0.24 mm thick in one working embodiment, while the polymeric material 28 may be 1.92 mm thick. In one working example, the polymeric material 28 is a high crystalline polypropylene that is laminated between two sheets of ENAU-5182 aluminum. It is generally contemplated that the aluminum sheet may be as great at 3 mm thick, or less than 0.2 mm thick. In addition, it is contemplated that the polymeric material 28 may be greater than 10 mm thick, or less than 0.2 mm thick. The thickness of the materials may largely depend on the type of polymeric material 28 that is utilized and the particular application. Different sizes and thicknesses of the protective panel 22 and the components of the protective panel 22 may vary, depending on the particular application. As previously noted, the polymeric material 28 may be filled with any number of reinforcing materials, including glass, Kevlar , carbon fiber, natural fiber, talc, and mineral fillers. In addition, the glass beads may be utilized to produce an isotactic foam in the polymeric material 28 to further reduce weight. It is also contemplated that the thickness of the two sheets of aluminum may vary. For example, the aluminum sheet proximate the inside of the seating assembly 10 may be thicker as this is the last layer through which standing protection would be afforded.
