Lateral edge 178 of the leg support 14 may extend away from the seat pan 122. Hinge elements 182 may extend from the lateral edge 174 of the leg support 14. The hinge elements 182 may be rotatably coupled to pins 186 that may extend from a front portion of the seat pan 122. An axis 190 may extend through the pins 186. A lift mechanism 26 for moving the leg support 14 between the stored position A and the deployed position B may be disposed between the leg support 14 and the seat 18. As such, FIGS. 3-6 show the attachment of the leg support 14 to the seating assembly frame 82. Additionally, FIGS. 3-6 show the bladder subassembly 54 disposed on the seat 18 and the bladder subassembly 58 disposed on the leg support 14.
Referring now to FIGS. 7-10, the leg support 14 is shown in relation to the carrier 126. The lift mechanism 26 is shown disposed between the carrier 126 and the leg support 14. As previously explained, the carrier 126 may be U-shaped. The carrier 126 may include legs 194 and a central portion 130. The central portion 130 may extend between the legs 194. The central portion 130 may be angled upward from the legs 194. The carrier 126 may be tubular. The leg support 14 may include a frame 162. The frame 162 of the leg support 14 may be defined by opposing lateral walls 198 and opposing longitudinal walls 202. The frame 162 may be further defined by connector walls 206 that may be disposed between each lateral wall 198 and each longitudinal wall 202. The leg support 14 may include a storage space 166 for receiving the lift mechanism 26. In the stored position A, the leg support 14 may be angled inward under the carrier 126 and positionable against the carrier 126. In the deployed position B, the leg support 14 may be angled outward from the seat 18 and away from the seat 18. As such, when the leg support 14 is in the stored position A, it may be positioned as close to the seat 18 as possible to provide storage space 166 beneath the seat 18 for storing passenger items, placing passenger legs, and other uses. Additionally, when the leg support 14 is in the stored position A, it may remain in the stored position A as the seating assembly 10 is rotated from the sitting position I (FIG. 3) to the standing position J (FIG. 3A).
With reference to FIGS. 7-8, the leg support 14 is shown in the stored position A, and the telescoping members 142 are shown in a corresponding retracted position M. Referring to FIGS. 9-10, the leg support 14 is shown in the deployed position B, and the telescoping members 142 are shown in a corresponding extended position N.
With reference to FIGS. 8-10, the lift mechanism 26 may include a base portion 210 coupled to an underside of the seat 18. The lift mechanism 26 may include a base portion 214 coupled to an underside of the leg support 14. Telescoping members 142 may be disposed between the base portion 210 coupled to the underside of the seat 18 and the base portion 214 coupled to the underside of the leg support 14. The telescoping members 142 may be coupled to the base portion 210 and may extend to the base portion 214. As the leg support 14 moves from the stored position A towards the deployed position B, the base portion 210 rotates around the central portion 130 of the carrier 126 in the direction shown by arrow 218. Each telescoping member 142 may have a first end 222 and a second end 230. The first end 222 of the telescoping member 142 may be attached to the first platform 226.

The second end 230 of the telescoping member 142 may be rotatably coupled to a bracket 238 extending away from the base portion 214 on the underside of the leg support 14. Two elongated channels 242 may be disposed in the underside of the leg support 14. When the telescoping members 142 are in the retracted position M, then the bracket 238 that receives the telescoping member 142 is slidably disposed in the elongated channels 242 and adjacent to the lateral edge 178 of the leg support 14. As the telescoping member 142 moves from the retracted position M to the extended position N, the bracket 238 that retains the second end 230 of the telescoping member 142 may move along the elongated channel 242 from the lateral edge 178 of the leg support 14 toward the lateral edge 174 of the leg support 14. It is to be understood that the leg support 14 may be moved between the stored position A, the deployed position B, and intermittent positions therebetween by powered actuation. A passenger may push a button to move the leg support 14 to a position chosen by the passenger. As such, the lift mechanism 26 may include various parts for moving the leg support 14 from the stored position A to the deployed position B.
Referring now to FIGS. 11-12, side views of the carrier 126, the lift mechanism 26, and the leg support 14 are shown. FIG. 11 shows the leg support 14 in the stored position A. FIG. 12 shows the leg support 14 in the deployed position B. With reference to FIG. 11, the base portion 210 is shown positioned along the carrier 126 when the leg support 14 is in the stored position A. With reference to FIG. 12, the base portion 210 is shown extending away from the carrier 126 when the leg support 14 is in the deployed position B. Additionally, when the leg support 14 is in the stored position A (FIG. 11), the second end 230 of the telescoping member 142 is directed toward the vehicle floor 32 and toward the latch assemblies 106 of the vehicle seating assembly 10. When the leg support 14 is in the deployed position B (FIG. 12), the second end 230 of the telescoping member 142 extends outward from the first end 222 of the telescoping member 142 in a direction substantially parallel to the vehicle floor 32.
With reference to FIG. 13, a top view of the carrier 126 and the leg support 14 in the stored position A is shown. The leg support 14 includes the frame 162. The carrier 126 is nested in the storage space 166 in the leg support 14. The telescoping members 142 are shown in the retracted position M that corresponds to the stored position A of the leg support 14.
Referring to FIG. 14, a bottom view of the carrier 126 and the leg support 14 in the stored position A is shown. The leg support 14 includes the frame 162.
Referring to FIG. 15, a bottom view of the leg support 14 in the deployed position B is shown. The telescoping members 142 are shown in the extended position N to correspond to the leg support 14 in the deployed position B. The lift mechanism 26 is shown extending between the carrier 126 and the leg support 14.
Referring to FIG. 16, a top view of the leg support 14 in the deployed position B is shown. The lift mechanism 26 is shown extending between the carrier 126 and the leg support 14.
Referring to FIG. 17, a front view of the carrier 126 and the leg support 14 in the stored position A is shown. Referring to FIG. 18, a back view of the carrier 126 and the leg support 14 in the stored position A is shown.
Referring to FIG. 19, a cross-sectional view taken along line XIX-XIX of FIG. 18 is shown. The leg support 14 is shown in the stored position A. The telescoping member 142 is shown in the retracted position M with a rod 250 disposed in the housing 254. A plate 258 supports the telescoping member 142. The plate 258 is shown in a rest position Q extending along the carrier 126. The plate 258 includes a pivot point 262. An axis 266 may be disposed through the pivot point 262. The hinge element 182 is disposed on the leg support 14. As such, while the axis 266 extending through the plate 258 and the axis 190 extending through the hinge elements 182 proximate the front of the seat pan 122 remain fixed, the lift mechanism 26 may move the leg support 14 between the stored position A of the leg support 14 and the deployed position B of the leg support 14.
Referring to FIG. 20, a front view of the carrier 126 and the leg support 14 in the deployed position B is shown. Referring to FIG. 21, a back view of the carrier 126 and the leg support 14 in the deployed position B is shown.
Referring to FIG. 22, a cross-sectional view taken along line XXII-XXII of FIG. 21 is shown. The leg support 14 is shown in the deployed position B. The telescoping member 142 is shown in the extended position N with the housing 254 extending away from the rod 250. The plate 258 for supporting the telescoping member 142 is shown disposed in an activated position R extending away from the carrier 126. The plate 258 is rotated from a rest position Q disposed along the carrier 126 (FIG. 19) to an activated position R extending away from the carrier 126 (FIG. 21). As the plate 258 rotates from the rest position Q extending along the carrier 126 to the activated position R extending away from the carrier 126, the plate 258 changes the position of the telescoping member 142 from a first position extending downward and inward towards the area beneath the carrier 126 to a second position extending outward and away from the carrier 126. As such, the rotation of the plate 258 from the rest position Q (FIG. 19) to the activated position R (FIG. 22) about the axis 266 of the plate 258 may cause the leg support 14 to rotate about the axis 190 disposed through the hinge elements 182. The extension of the telescoping member 142 from the retracted position M to the extended position N may cause the additional rotation of the leg support 14 to rotate about the axis 190 disposed through the hinge elements 182.
Referring to FIG. 23, a bladder subassembly 54 that may be disposed in the seat 18 is shown. The bladder subassembly 54 may be attached to a substrate 282, such as a heavy felt. The bladder subassembly 54 may be attached to the substrate 282 with staples 286, a plastic fastener, or another attachment. The bladder assembly 22 may be disposed beneath the thigh of a passenger. The bladder assembly 22 may include a first bladder portion 290 and a second bladder portion 294. The first bladder portion 290 may be disposed below one leg of a passenger. The second bladder portion 294 may be disposed below another leg of a passenger. The first bladder portion 290 may include a bladder that may be inflatable between a deflated state E and inflated state F. The second bladder portion 294 may include a bladder that may be inflatable between a deflated state E and an inflated state F. A pump 298 may supply air to and withdraw air from the first bladder portion 290 and the second bladder portion 294. Hoses 302 may extend from the pump 298 to the first bladder portion 290 and the second bladder portion 294. The first bladder portion 290 and the second bladder portion 294 may be inflated separately or in unison to provide custom support to each leg of a passenger.
Referring to FIG. 24, a bladder subassembly 58 that may be disposed in the leg support 14 is shown. The bladder subassembly 58 may include a first bladder portion 314 and a second bladder portion 318. The first bladder portion 314 and the second bladder portion 318 may each be disposed under a leg of the passenger. The first bladder portion 314 and the second bladder portion 318 may each contain three bladders 314A, 314B, 314C and 318A, 318B, 318C, respectively, arranged in a shingled arrangement 322. The shingled arrangement 322 may also be described as an overlapping arrangement. In the overlapping arrangement, bladders 314A, 314B, 314C may be positioned so that bladder 314B overlaps bladder 314A while bladder 314C overlaps bladder 314B. In overlapping examples of bladders 314A, 314B, 314C, overlapping bladders 314B and 314C may have an overlap area of greater than or equal to about 1%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90% or greater than or equal to about 99% of the bladder they are disposed over (314A and 314B, respectively). In some arrangements, bladder 314B may overlap bladder 314A, and bladder 314C may overlap both bladders 314B and 314A. The overlapping arrangement described for bladders 314A, 314B, 314C is also applicable to bladders 318A, 318B, 318C. Each of the six bladders 314A, 314B, 314C, 318A, 318B, 318C may have a separate hose 302 for connecting the bladders 314A, 314B, 314C, 318A, 318B, 318C to a pump 298. Each of the six bladders 314A, 314B, 314C, 318A, 318B, 318C may be selectively inflatable between a deflated state E and an inflated state F. The pump 298 may supply air to the bladders 314A, 314B, 314C, 318A, 318B, 318C, and the pump 298 may withdraw air from the bladders 314A, 314B, 314C, 318A, 318B, 318C. The pump 298 may be activated to inflate and deflate each of the bladders 314A, 314B, 314C, 318A, 318B, 318C with an individualized fluid amount. The pump 298 may be activated to inflate or deflate several bladders in unison. For example, bladders 314A, 314B, 314C disposed under one leg of a passenger may be inflated or deflated to achieve an amount of fluid in the bladders 314A, 314B, 314C that may be different from the amount of fluid inflated or deflated in bladders 318A, 318B, 318C. Also, the pump may be activated to inflate or deflate all of the bladders 314A, 314B, 314C, 318A, 318B, 318C with the same fluid amount. The fluid amount in a bladder (314A, 314B, 314C, 318A, 318B, 318C or a bladder portion 290 or 294) determines the contour of the bladder 314A, 314B, 314C, 318A, 318B, 318C or the bladder portion 290 or 294. Generally, the more fluid that is in the bladder 314A, 314B, 314C, 318A, 318B, 318C or the bladder portion 290 or 294, the more the bladder 314A, 314B, 314C, 318A, 318B, 318C or the bladder portion 290 or 294 expands.
It is contemplated that in addition to air or instead of air various other fluids may be used to inflate the bladders.
It will be understood by one having ordinary skill in the art that construction of the described concepts, and other components, is not limited to any specific material. Other exemplary embodiments of the concepts disclosed herein may be formed from a wide variety of materials, unless described otherwise herein.
For purposes of this disclosure, the term “coupled” (in all of its forms: couple, coupling, coupled, etc.) generally means the joining of two components (electrical or mechanical) directly or indirectly to one another. Such joining may be stationary in nature or movable in nature. Such joining may be achieved with the two components (electrical or mechanical) and any additional intermediate members being integrally formed as a single unitary body with one another or with the two components. Such joining may be permanent in nature, or may be removable or releasable in nature, unless otherwise stated.
As used herein, the term “about” means that amounts, sizes, formulations, parameters, and other quantities and characteristics are not and need not be exact, but may be approximate and/or larger or smaller, as desired, reflecting tolerances, conversion factors, rounding off, measurement error and the like, and other factors known to those of skill in the art. When the term “about” is used in describing a value or an end-point of a range, the disclosure should be understood to include the specific value or end-point referred to. Whether or not a numerical value or end-point of a range in the specification recites “about,” the numerical value or end-point of a range is intended to include two embodiments: one modified by “about,” and one not modified by “about.” It will be further understood that the end-points of each of the ranges are significant both in relation to the other end-point, and independently of the other end-point.
The terms “substantial,” “substantially,” and variations thereof as used herein are intended to note that a described feature is equal or approximately equal to a value or description. For example, a “substantially planar” surface is intended to denote a surface that is planar or approximately planar. Moreover, “substantially” is intended to denote that two values are equal or approximately equal.
It is also important to note that the construction and arrangement of the elements of the disclosure, as shown in the exemplary embodiments, are illustrative. Although a few embodiments of the present innovations have been described in detail in this disclosure, those skilled in the art who review this disclosure will readily appreciate that many modifications are possible (e.g., variations in sizes, dimensions, structures, shapes and proportions of the various elements, values of parameters, mounting arrangements, use of materials, colors, orientations, etc.) without materially departing from the novel teachings and advantages of the subject matter recited. For example, elements shown as integrally formed may be constructed of multiple parts, or elements shown as multiple parts may be integrally formed, the operation of the interfaces may be reversed or otherwise varied, the length or width of the structures and/or members or connectors or other elements of the system may be varied, and the nature or numeral of adjustment positions provided between the elements may be varied. It should be noted that the elements and/or assemblies of the system may be constructed from any of a wide variety of materials that provide sufficient strength or durability, in any of a wide variety of colors, textures, and combinations. Accordingly, all such modifications are intended to be included within the scope of the present innovations. Other substitutions, modifications, changes, and omissions may be made in the design, operating conditions, and arrangement of the desired and other exemplary embodiments without departing from the spirit of the present innovations.
It will be understood that any described processes, or steps within described processes, may be combined with other disclosed processes or steps to form structures within the scope of the present disclosure. The exemplary structures and processes disclosed herein are for illustrative purposes and are not to be construed as limiting.
It is to be understood that variations and modifications can be made on the aforementioned structure without departing from the concepts of the present disclosure, and further it is to be understood that such concepts are intended to be covered by the following claims unless these claims by their language expressly state otherwise.
