Referring to the embodiment generally illustrated in FIGS. 1-10, reference numeral 10 generally designates a vehicle seating assembly having a seat 12 including a support frame 14. A seatback 16 is pivotally coupled with the seat 12 and is adjustable between a passenger support position 18 configured to support the weight of a passenger and a cargo position 20 wherein the seatback 16 is folded forward to a substantially horizontal position. A seat cushion 22 includes a dynamic forward portion 24 and a generally static rearward portion 26. An articulation feature 30 is disposed below the forward portion 24 of the seat cushion 22. The articulation feature 30 is operable between a deployed position 32 and a non-deployed position 34. Movement to the deployed position 32 results in the dynamic forward portion 24 of the seat cushion 22 being adjusted to a raised position. Movement to the non-deployed position 34 results in the dynamic forward portion 24 of the seat cushion 22 being adjusted to a lowered position that allows the seatback 16 to fold forward to the cargo position 20.

With reference now to FIGS. 1-3, the vehicle seating assembly 10 as set forth herein is generally configured for use as rear seating for a vehicle. It is contemplated that the vehicle may be a sport utility vehicle, a van, a car, etc. It will also be contemplated that the support frame 14 could take on a variety of constructions, and is not limited to the structure as set forth herein. Further, the concept as set forth herein can be applied to bench-type seating, 40/60 seating, or any other vehicle seating arrangement, as understood by one having ordinary skill in the art. As shown in FIG. 1, the vehicle seating assembly 10 may also include a headrest 36, seatbelt assemblies 37, and various other components generally found in a backseat of a vehicle.

With reference now to FIGS. 2 and 3, the illustrated embodiment includes a recliner heart 40 about which the seatback 16 can rotate relative to the seat 12. In the illustrated embodiment, the recliner heart 40 is configured to allow rotation of the seatback 16 to rotate forward to a substantially horizontal position, such that the seatback 16 is adjacent to and in abutting contact with the seat 12, and more specifically, to the seat cushion 22. In the illustrated embodiment, the seatback 16 includes a lower seatback 42 that is deeper than an upper seatback 44. This construction is generally complementary to the seat 12. More specifically, the forward portion 24 of the seat cushion 22 is thicker than the generally static rearward portion 26. As a result, when the seatback 16 is folded forward to a substantially horizontal position, the front face of the seatback 16 generally conforms to and is complementary with the seat 12. To aid in reaching a substantially horizontal position, the articulation feature 30 moves from the deployed position 32 (FIG. 2) to the non-deployed position 34 (FIG. 3). In the embodiment illustrated in FIGS. 2 and 3, the articulation feature 30 includes a compression spring 50. The compression spring 50 compresses when the seatback 16 moves to the horizontal position. It is generally contemplated that the weight of the seatback 16 may compress the compression spring 50. However, the compression spring 50 may be moved to the non-deployed position 34 via a motorized unit, a ratcheting system, etc., configured to draw down the dynamic forward portion 24 of the seat cushion 22 to accommodate for the seatback 16 when placed in the horizontal position. Notably, the articulation feature 30, which in this case is the compression spring 50, is generally positioned between the seat frame 14 and a dynamic member 52. The dynamic member 52 generally defines a rigid cushion support and moves as part of the dynamic forward portion 24 of the seat cushion 22 when the articulation feature 30 moves between the deployed position 32 and the non-deployed position 34. The dynamic member 52 may be constructed from a flexible material, including, but not limited to, polymers, metals, etc. In addition, the dynamic member 52 may be coupled with the seat frame 14 via a weld, an epoxy, mechanical fasteners, etc. In the illustrated embodiment, the dynamic member 52 is connected to the seat frame 14 at a rearward junction 54. The resulting seating assembly provides a comfortable seating surface for a passenger and can be easily converted to a cargo space, when desired.

With reference now to FIGS. 3-3B, it is also contemplated that a lever 55, which generally defines an activation device for the vehicle seating assembly 10, can be adjusted to lower the articulation feature 30 from the deployed position 32 to the non-deployed position 34. As illustrated, the lever 55 is adjusted prior to the seatback 16 being moved to the cargo position 20. It is also generally contemplated that the lever 55 could be replaced with a motorized system, wherein a switch activates a motor that draws down the dynamic member 52, and consequently lowers the articulation feature 30 to accommodate the seatback 16 when moved to the cargo position.

With reference now to FIGS. 4 and 5, it is also contemplated that the vehicle seating assembly 10 may be utilized with only the dynamic member 52 and seat frame 14. As illustrated, the dynamic member 52 includes a forward distal end 56 that vertically adjusts and a rearward proximal end 57 that is operably coupled to the seat frame 14 at the rearward junction 54. As shown in FIGS. 4 and 5, the dynamic member 52 and the connection of the dynamic member 52 with the seat frame 14 is such that the dynamic member 52 can flex downward (FIG. 5) when the seatback 16 is moved to the horizontal position. In this instance, the dynamic member 52 defines a composite support that may be constructed from polymers, metals, or both. It is contemplated that the dynamic member 52 can be drawn down by the weight of the seatback 16, or by a mechanical member that is manually or automatically actuated when a passenger desires to move the seatback 16 to the cargo position 20. It is generally contemplated that the dynamic member 52 will be constructed of a resilient material, such as spring steel or an elastic polymer, such that the dynamic member 52, and consequently, the articulation feature 30, is biased to the raised position associated with the passenger support position 18.

With reference now to FIGS. 6 and 7, in another embodiment, one or more spring steel supports 60 may be positioned between the dynamic member 52 and the seat frame 14. It is contemplated that the spring steel supports 60 may be disposed directly below the dynamic member 52, and are urged downward under the weight of the seatback 16, or as previously noted, with regard to the embodiments illustrated in FIGS. 2-5, the spring steel supports 60 may be urged downwardly manually by a passenger or by an automatic system that may include a motor.

With reference now to FIGS. 8 and 9, in another embodiment, the articulation feature 30 includes an air bladder 70 that is operably connected with a bladder pump 72 via a bladder inflation and deflation line 74. In this embodiment, the air bladder 70 can be adjusted and inflated to provide sufficient support to the forward portion 24 of the seat cushion 22 and support the backs of the legs of a passenger. When the passenger desires for the seatback 16 to move to the cargo position 20, the passenger simply urges the seatback 16 downward and the bladder pump 72 can automatically or manually be activated to allow air to leave the air bladder 70 via a valve proximate the air bladder 70 or through the inflation and deflation line 74. It is also contemplated that a passenger can adjust the height and/or rigidity of the forward portion 24 of the seat cushion 22 by activating the bladder pump 72. In this manner, the passenger can adjust the forward portion 24 of the seat cushion 22 to a desired setting. A static member 53 and the dynamic member 52 are disposed within the seat 12 and the air bladder 70 is disposed therebetween.

With reference now to FIGS. 10 and 11, in yet another embodiment, a polymeric composite support member 80 is positioned between the dynamic member 52 and the seat frame 14. The polymeric composite support member 80 includes an outer durable shell 82 that extends around a foam core having a high degree of resilience. In addition, the foam core is configured to be compressed when the seatback 16 is folded forward to a substantially horizontal position, resulting in the seatback 16 being in the cargo position 20. It is contemplated that when the seatback 16 is moved back to the passenger support position 18, the polymeric composite support member 80 returns to its original shape to provide support to the legs of a passenger seated on the vehicle seating assembly 10.
