DETAILED DESCRIPTION

As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention that may be embodied in various and alternative forms. The figures are not necessarily to scale; some features may be exaggerated or minimized to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ the present invention.

Conventionally, for a vehicle seat assembly, a backrest is pivotally connected to a seat cushion for adjustment of recline of the backrest. Additionally, the backrest may pivot forward to a position whereby the backrest lies flat upon the seat cushion so that a rear surface of the backrest operates as a load floor for cargo. The backrest may also recline rearward to a position flat and adjacent to the seat cushion to provide a reclined seating or lying position for an occupant. Such adjustability may provide clearance between the backrest and the seat cushion, which may form a gap.

FIG. 1 illustrates a rear perspective of a seat assembly 10 according to an embodiment. The seat assembly 10 is depicted in an upright or design position for supporting a passenger in a seating position. Although the seat assembly 10 is illustrated as a vehicle seat assembly, the seat assembly 10 may be utilized for any seating arrangement, such as a land vehicle, a lounge chair, aircraft, watercraft, or the like.

The seat assembly 10 includes a backrest 12 pivotally connected to a seat cushion 14. The seat cushion 14 is adapted to be mounted to a vehicle floor, as is known in the art. A head restraint 13 is supported upon the backrest 12 to receive and support a head of the occupant. The backrest 12 is connected to, and supported by, the seat cushion 14 by a recline mechanism 15 for permitting pivotal adjustment of the backrest 12 relative to the seat cushion 14. As illustrated, there is a gap 16 between the backrest 12 and the seat cushion 14. A trim assembly 18 is provided to act as a curtain to cover the gap 16.

The trim assembly 18 is illustrated in phantom in FIG. 1. The trim assembly 18 is illustrated in greater detail in FIGS. 2-6. The trim assembly 18 is sewn to a lower region of a rear surface 19 of the backrest 12 to cover the gap 16 when the backrest 12 is in the upright position of FIG. 1. The trim assembly 18 also covers the gap 16 in the forward position of the backrest 12 (FIGS. 2 and 3), and the rearward position of the backrest 12 (FIG. 4).

FIGS. 2 and 3 illustrate the seat assembly 10 in a forward position. The trim assembly 18 includes a first trim panel 20 pivotally connected to the lower region of the backrest 12 to cover the gap 16. A second trim panel 22 is connected to the first trim panel 20 to cover the gap 16 when the backrest 12 is in a forward position relative to the seat cushion 14. A third trim panel 26 is pivotally connected to the second trim panel 22 and spaced apart from the first trim panel 20 to cover a portion of the seat cushion 14 in the forward position.

Referring now to FIG. 4, the trim assembly 18 is shown when the backrest 12 is reclined to a rearward position. It is shown that the second trim panel 22 is pivotally connected to the first trim panel 20 to pivot away from the seat cushion 14 when the backrest 12 is in a rearward position. Additionally, the third trim panel 26 is sized to contact and slide upon the vehicle floor in the rearward position to translate away from the seat cushion 14.

Referring to FIGS. 2-4, the trim assembly 18 is illustrated with three panels 20, 22, 26. Although three panels 20, 22, 26 are illustrated, any suitable plurality of panels may be employed to cover the gap 16 in the seat assembly 10. For the depicted embodiment, only three panels 20, 22, 26 are employed to cover the gap 16, and to move with the range of pivotal adjustment of the backrest 12 relative to the seat cushion 14.

Each of the trim panels 20, 22, 26 is formed from a polymeric material as a plastic board. A first strip of nonwoven material 24 interconnects the first trim panel 20 and the second trim panel 22. Likewise, a second strip of nonwoven material 28 interconnects the second trim panel 22 and the third trim panel 26. The nonwoven material 24, 28 is thin and flexible to interconnect sequential panels 20, 22, 26, while permitting the panels 20, 22, 26 to pivot relative to each other.

The first trim panel 20, the second trim panel 22, and the third trim panel 26, each have a carpet material 30 over the trim panel 20, 22, 26. The carpet material 30 is provided on a rear side of the panels 20, 22, 26, relative a front direction of the backrest 12, to be exposed away from the seat assembly 10. According to an embodiment, the trim panels 20, 22, 26 are sewn to the nonwoven material 24, 28 before the carpet material 30 is sewn over the trim panels 20, 22, 26 and the nonwoven material 24, 28. The carpet material 30 has a stiffness that is greater than the nonwoven material 24, 28 to protect the trim panels 20, 22, 26 from cargo and wear.

When the backrest 12 is the forward position of FIGS. 2 and 3, the first trim panel 20 and the second trim panel 22 cover the gap 16. In this position, the trim assembly 18 also forms part of a load floor for cargo with the rear surface 19 of the backrest 12. The rear surface 19 of the backrest 12 is also carpeted.

Referring now to FIGS. 5 and 6, biasing members 32 are attached to the first trim panel 20 and a lower region of the rear surface 19 of the backrest 12 to bias the first trim panel 20 against the rear surface of the backrest 12. The biasing member 32 can be made of elastic bands, which are sewn to the first trim panel 20 and the backrest rear surface 19.

Referring again to FIG. 1, in the upright position of the seat assembly 10, the trim assembly 18 extends downward from the backrest 12. The elastic bands 32 retract the first trim panel 20 against the rear surface 19 of the backrest 12. The second trim panel 22 and the third trim panel 26 extend from the first trim panel 20 in an upright orientation, along a housing 34 of the recline mechanism 15. When the backrest 12 is pivoted to the forward position of FIGS. 2, and 3, the first trim panel 20 is pivoted generally flat upon the rear surface 19 of the backrest 12. Consequently, the second trim panel 22 lies upon the recline mechanism housing 34, pivoted below the first trim panel 20, and covering the gap 16. The third trim panel 26 hangs from second trim panel 22 along the recline mechanism housing 34 covering a portion of the seat cushion 14.

When the backrest 12, is pivoted rearward to the position of FIG. 4, the third trim panel 26 slides along the recline mechanism housing 34 and the vehicle floor to pivot away from the seat cushion 14. The second trim panel 22 also slides along the recline mechanism housing 34 and is pivoted away from the seat cushion 14. The first trim panel 20 is slid along the recline mechanism housing 34 thereby overcoming the resistance of the elastic bands 32 and pivoting away from the rear surface 19 of the backrest 12.

While various embodiments are described above, it is not intended that these embodiments describe all possible forms of the invention. Rather, the words used in the specification are words of description rather than limitation, and it is understood that various changes may be made without departing from the spirit and scope of the invention. Additionally, the features of various implementing embodiments may be combined to form further embodiments of the invention.
