Abstract

A vehicle slouch seat having a carriage that includes a front side and a rear side. A link element is located on a rear side of the carriage and a slideable element is located on the front side of the carriage. A cushion is movable in an upward direction with the carriage connected to a base structure at one of a plurality of latch points. The cushion is prevented being rotated in the upward direction via a cushion rotational prevention structure with the carriage connected to the base structure at another one of the plurality of latch points.

First claim

What is claimed is:

1. A vehicle slouch seat, comprising:
a cushion;
a base structure;
a carriage comprising a front side and a rear side;
a link element located on said rear side of said carriage;
a slidable element located on said front side of said carriage;
wherein said slidable element moves relative to said base structure when said carriage moves from one of a plurality of latching points to another one of said plurality of latching points;

a seat connecting structure;
wherein said seat connecting structure is connected to a seat back structure and is connected to said carriage;
wherein said seat connecting structure has a flange that extends toward said carriage;
wherein a cushion rotation prevention structure of said base structure has a flange that extends toward said seat connecting structure and is selectively engagable with said flange of said seat connecting structure; and
wherein said flange of said seat connecting structure engages said flange of said cushion rotation prevention structure when said cushion is not in a rearmost position allowing said cushion to move in an upward direction when said cushion is in said rearmost position.

2. A vehicle slouch seat in accordance with claim 1 , further comprising:
a latching element; and
wherein said carriage and said cushion are locked to said base structure by said latching element.

3. A vehicle slouch seat of claim 1 , wherein said cushion is in a substantially upright position when said carriage in a predetermined position.

4. A vehicle slouch seat, comprising:
a carriage;
a base structure;
a link element connected to said carriage; and
a slidable element connected to said carriage;
a latching element, wherein at least a portion of said carriage is connected to said base structure at one of a plurality of latching points by said latching element;
a cushion connected to said carriage;
wherein said cushion is movable from one position to another position with said carriage connected to said base structure at one of said plurality of latching points;
wherein said cushion is movable relative to said carriage with said carriage connected to said base structure at one of said plurality of latching points; and
wherein said cushion is in a substantially horizontal position in said one position, and wherein said cushion is in a substantially vertical position in said another position.

5. A vehicle slouch seat of claim 4 , wherein said cushion is fixed to said carriage and said base structure by said latching element; or
wherein said cushion is fixed dynamically to said carriage by an inertia latch.

6. A vehicle slouch seat of claim 4 , wherein said cushion is fixed relative to said carriage when said carriage connected to said base structure at another one of said plurality of latching points.

7. A vehicle slouch seat of claim 4 , wherein said link element is pivotably connected to said base structure.

8. A vehicle slouch seat of claim 4 , wherein said cushion has a first end portion a second end portion;
wherein said first end portion of said cushion is located adjacent to at least a portion of said carriage,
wherein said second end portion of said cushion is located a first distance from said base structure when said carriage is connected at another one of said plurality of latching points;
wherein said second end portion of said cushion is located a second distance from said base structure when said carriage is connected at yet another one of said plurality of latching positions; and
wherein said second distance is greater than said first distance.

9. The slouch seat of claim 4 , further comprising a latching mechanism having a first latch element and a second latch element;
wherein said first latch element selectively interacts with said second latch element to lock and unlock said seat connecting structure and/or said cushion to and/or from said carriage and said base structure; and
wherein said cushion is movable in an upward direction when said first latch element is moved out of engagement with said second latching element.

10. A vehicle slouch seat of claim 4 , wherein said slidable element moves relative to said base structure when said carriage moves from said one of said plurality of latching points to another one of said plurality of latching points.

11. A slouch seat of claim 10 , wherein said link element is in a first position when said carriage is connected to said base structure at one of said plurality of latching points,
wherein said link element is at a first angle relative to said carriage when said carriage at said one of said plurality of latching points;
wherein said link element is located at a second angle relative to said carriage when said carriage is connected to said base structure at said another one of said plurality of latching points;
wherein said link element is located at a third angle relative to said carriage when said carriage connected to said base structure at yet another one of said plurality of latching points; and
wherein said first angle is less than said second angle and said third angle.

12. A vehicle slouch seat of claim 4 , further comprising:
a cushion rotational prevention member for restricting movement of said cushion in a substantially vertical position when said carriage connected to said base structure at another one of said plurality of latching points.

13. A vehicle slouch seat of claim 12 , wherein said plurality of latching points comprise yet another latching point; and
wherein movement of said cushion is restricted in said upward direction by said cushion rotational prevention member with said carriage connected to said base structure at said yet another latching point.

14. A vehicle slouch seat of claim 12 , wherein said base structure comprises a cushion stop portion; and
wherein said cushion rotational prevention member comprises said cushion stop portion.

15. A slouch seat of claim 14 , wherein said cushion has an end portion;
wherein said end portion extends to a position beyond said cushion stop portion of said base structure when said carriage is connected to said base structure at said one of said plurality of latching positions;
wherein said end portion is located at a position above said cushion stop portion of said base structure when said carriage is connected to said base structure at said another one of said plurality of latching points; and
wherein said end portion is located at another position above said cushion stop portion of said base structure when said carriage is connected to said base structure at yet another one of said plurality of latching points.

16. A vehicle slouch seat, comprising:
a cushion;
a base structure;
a carriage comprising a front side and a rear side;
a link element located on said rear side of said carriage;
a slidable element located on said front side of said carriage;
wherein said slidable element moves relative to said base structure when said carriage moves from one of a plurality of latching points to another one of said plurality of latching points;

a seat connecting structure;
wherein said seat connecting structure is connected to a seat back structure and is connected to said carriage;
wherein said seat connecting structure has a flange;
wherein a cushion rotation prevention structure of said base structure has a flange that is selectively engagable with said flange of said seat connecting structure;
wherein said flange of said seat connecting structure engages said flange of said cushion rotation prevention structure when said cushion is not in a rea
