Abstract

A vehicle seat includes cushion and a seatback coupled with the cushion. At least one of the seatback and the cushion includes a base body defining an internal cavity open on a side of the base portion and a secondary body slidably mounted with the base body so as to be extendible out of the internal cavity beyond the side of the base body and retractable at least partially within the cavity.

First claim

What is claimed is:

1. A vehicle seat, comprising:
a cushion coupled with a seatback,
each of the seatback and the cushion including:
a respective base body defining an internal cavity open on a side of the base body; and
a respective secondary body slidably mounted with the respective base body so as to be extendible out of the respective internal cavity beyond the side of the respective base body and retractable at least partially within the respective internal cavity.

2. The vehicle seat of claim 1 , wherein:
each of the seatback and the cushion respectively includes a support structure and a coverstock defining a first seating surface;
the respective base body included in one of the seatback and the cushion includes the support structure and the coverstock of one of the seatback and the cushion; and
the respective internal cavity is defined by the respective support structure and is inside the coverstock of one of the seatback and the cushion.

3. The vehicle seat of claim 1 , wherein one of the seatback and the cushion includes an extension member coupled between the base body and the secondary body.

4. The vehicle seat of claim 3 , wherein the extension member includes a retention portion coupled with the respective base body and a telescoping portion slidably received with the retention portion and coupled with the respective secondary body.

5. The vehicle seat of claim 1 , wherein the base bodies each define a first seating surface and the secondary bodies each define a second seating surface positionable laterally adjacent to the respective first seating surface by extension of the respective secondary body.

6. The vehicle seat of claim 5 , wherein each secondary body is also moveable with respect to the respective base body in a direction normal to the respective first seating surface to align the respective second seating surface with the respective first seating surface in the direction normal to the respective first seating surface when the secondary body is extended out of the cavity and to position the respective second seating surface below the respective first seating surface when the secondary body is retracted at least partially within the cavity.

7. The vehicle seat of claim 1 , wherein:
each base body is a first base body; and
each of the seatback and the cushion further includes a second base body defining an internal cavity open on a side of the second base portion facing the side of the respective first base body, the respective secondary body being further slidably mounted with the second base body so as to be extendible out of the internal cavity of the second base body beyond the side thereof and retractable at least partially within the cavity of the second base body.

8. The vehicle seat of claim 7 , wherein the seat is configurable between:
a first condition, wherein portions of the secondary bodies are respectively retracted within the internal cavities of the respective first base body and the respective second base body; and
a second condition, wherein the secondary bodies are extended from the cavities of both the respective first base body and the respective second base body.

9. The vehicle seat of claim 8 , wherein the seat defines a first width in the first condition and a second width in the second condition, the second width being greater than the first width.

10. A vehicle seat assembly, comprising:
a first side portion including a first cushion and a first seatback;
a second side portion including a second cushion and a second seatback and slidably mounted with respect to the first side portion, wherein at least one of the first side portion and the second side portion defines an internal cavity; and
a central portion coupled between at least one of the first and second cushions or the first and second seatbacks of the first side portion and the second side portion and collapsible during sliding of the second side portion toward the first side portion.

11. The vehicle seat assembly of claim 10 , wherein
the central portion is slidably mounted with the internal cavity so as to be extendible out of the internal cavity and is collapsible by retracting at least partially within the cavity.

12. The vehicle seat assembly of claim 11 , further including an extension member coupled between the central portion and the at least one of the first side portion and the second side portion, wherein:
the extension member slidably mounts the central portion with the internal cavity.

13. The vehicle seat assembly of claim 10 , wherein the central portion defines a first section and a second section;
the first section is hingedly coupled with the at least one of the a cushion or a seatback of the first side section along a first axis;
the second section is hingedly coupled with the at least one of the cushion or the seatback of the second side section along a second axis;
the first section and the second section are hingedly coupled together along a third axis; and
the central portion is collapsible by rotation of the first section and the second section respectively about the first axis and the second axis, the first, second, and third axes being parallel.

14. The vehicle seat assembly of claim 10 , wherein the central portion is extendible during sliding of the second side portion away from the first side portion.

15. The vehicle seat assembly of claim 14 , wherein:
the seat is configurable in a first condition including collapsing of the central portion and sliding of the second side portion into contact with the first side portion, wherein the seat defines a first width;
the seat is configurable in a second condition including extension of the central portion and sliding of the second side portion away from the first side portion, wherein the seat defines a second width; and
the second width is greater than the first width.

16. The vehicle seat assembly of claim 10 , further including a track with which the first and second side portions are slidably coupled, wherein:
the coupling of the second side portion with the track slidably mounts the second side portion with respect to the first side portion; and
the second side portion is retainable in the first condition and the second condition by releasable fixation with the track.

17. A vehicle, comprising:
a seat, including:
a cushion; and
a seatback coupled with the cushion;

wherein the cushion includes:
a first base body defining an internal cavity open on a side of the base body; and
a secondary body slidably mounted with the base so as to be extendible out of the cavity beyond the side of the base body and retractable at least partially within the cavity; and

wherein the seatback includes a second base body defining an internal cavity open on a side of the second base body facing the side of the first base body, the secondary body being further slideably mounted with the second base body so as to be extendible out of the internal cavity of the second base body beyond the side thereof and retractable at least partially within the cavity of the second base body.

18. The vehicle of claim 17 , wherein:
the seat is configurable among a first condition in which portions of the secondary body are respectively retracted within the internal cavities of the first base body and the second base body and a second condition in which the secondary body is extended from the cavities of both the first base body.

19. The vehicle of claim 18 , further defining a pair of oppositely disposed rear doors and a third row bench sea
