Abstract

A seating system includes a base, and a seat mounted on the base and defining a seating surface. A backrest is configured for movement relative to the base and the seat between a first position and a second position by a backrest transfer arrangement having a movable pivot axis configuration. In the second position, the backrest defines a working surface spaced above and lying generally parallel to the seating surface.

First claim

What is claimed is:

1. A seating system comprising:
a base;
a seat mounted on the base, and defining a seating surface; and
a backrest configured for movement relative to the base and the seat between a first position and a second position by a backrest transfer arrangement having a movable pivot axis configuration,
wherein, in the second position, the backrest defines a working surface spaced above and lying generally parallel to the seating surface;
wherein the pivot axis configuration is defined by a pivoting linkage arrangement;
wherein the pivoting linkage arrangement includes at least one bent link and at least one straight link;
wherein the bent link and the straight link are spaced from each other when the backrest is in the first position;
wherein the bent link engages with the straight link to support the backrest in the second position.

2. The seating system of claim 1 , wherein the backrest transfer arrangement includes at least one motion assistance device for assisting movement of the backrest between the first position and the second position.

3. A seating system comprising:
a seat defining a seating surface;
a base mounting the seat thereon and having a raised support surface extending above the seat; and
a backrest mounted to the raised support structure on the base for movement relative to the seat between a raised position and a horizontal position extending above the seat and defining a work surface lying parallel to the seating surface,
wherein the backrest is adjustably connected to the raised support structure by a backrest transfer arrangement including a pair of transfer assemblies mounted between opposed side members of the backrest and opposed side walls of the raised support structure, each of the transfer assemblies being provided with a movable pivot axis configuration;
wherein each of the transfer assemblies includes a pivoting linkage arrangement and a motion assistance device;
wherein the pivoting linkage arrangement includes a pair of links, each having one end pivotally connected to one of the opposed side members of the backrest at a fixed pivot, and an opposite end pivotally joined to one of the side walls of the raised support surface at another fixed pivot.

4. The seating system of claim 3 , wherein the pair of links includes a bent link and a straight link.

5. The seating system of claim 4 , wherein the bent link and the straight link are engaged with each other when the backrest is in the horizontal position.

6. The seating system of claim 4 , wherein the motion assistance device has one end pivotally attached to the one of the side wells of the raised support surface, and an opposite end pivotally coupled to the straight link.

7. A seating system comprising:
a base having a front end, a rear end and opposed side members;
a seat mounted on the base and defining a seating surface; and
a backrest movably attached to the base by a pair of transfer assemblies enabling movement of the backrest between a raised position and a horizontal position,
wherein, in the horizontal position, the backrest defines a working surface which is spaced above and lies generally parallel to the seating surface,
wherein each of the transfer assemblies include a mounting plate fixed to one of the side members of the base, a bent link having one end pivotally connected about a first pivot axis to a side portion of the backrest, and an opposite end pivotally secured about a second pivot axis to the mounting plate, and a straight link having one end pivotally connected about a third pivot axis to the side portion of the backrest, and an opposite end pivotally secured about a fourth pivot axis to the mounting plate,
wherein the first pivot axis and the second axis remain stationary and immovable with respect to the backrest and are movable relative to the base and the seat.

8. The seating system of claim 7 , wherein the third pivot axis and the fourth pivot axis are stationary and immovable relative to the base and the seat.

9. The seating system of claim 7 , wherein each of the transfer assemblies also includes a motion assistance device having one end pivotally connected to the mounting plate, and an opposite end pivotally secured to the one end of the straight link.

10. The seating system of claim 9 , wherein the motion assistance device is an extendable and retractable gas strut.

11. The seating system of claim 7 , wherein the backrest is held in the horizontal position by engagement of the one end of the straight link with a retainer surface formed in the bent link.

12. The seating system of claim 7 , wherein, with the backrest in the raised position, the seating system defines an aft-facing seat at the rear end of the base, and the front end of the base includes at least one forward-facing seat.

13. A seating system for a marine vessel, the seating system comprising:
a seat that defines a seating surface;
a base that supports the seat and has a raised support structure that extends transversely relative to the seating surface;
a backrest having opposing sides including a back-engaging surface and a work surface that is opposite the back-engaging surface; and
a backrest transfer arrangement that couples the backrest to the base so that the backrest is movable relative to the base and the seat into and between a back-engaging position and a working position,
wherein in the back engaging position the backrest is positioned so that the work surface faces the raised support structure and the back-engaging surface extends transversely relative to the seating surface, and wherein in the working position the backrest is positioned so that the back-engaging surface faces the seat and the work surface extends transversely with respect to the raised support structure,
wherein the backrest transfer arrangement comprises a pair of transfer assemblies mounted on opposed sidewalls of the raised support structure, and
wherein each of the pair of transfer assemblies comprises first and second links, each of the first and second links having an end that is pivotably secured to the backrest at a pivot axis that remains fixed with respect to the backrest and an opposite end that is pivotably secured to the base at a pivot axis that remains fixed with respect to the base.

14. The seating system according to claim 13 , wherein the pivot axis that remains fixed with respect to the backrest is moved with respect to the base when the backrest is moved into and out of the back-engaging position and working position.

15. The seating system according to claim 14 , wherein the first link is bent, and wherein in the working position the first link rests on top of the end of the second link that is pivotably secured to the backrest so as to support the backrest.

16. The seating system according to claim 15 , wherein in the back engaging position the pivot axis of the second link that remains fixed with respect to the backrest is vertically lower than the pivot axis of the second link that remains fixed with respect to the base.

17. The seating system according to claim 16 , wherein the working position that pivot axis of the second link that remains fixed with respect to the backrest is vertically higher than the pivot axis of the second link that remains fixed with respect to the base.

18. The seating system according to claim 16 , wherein the backrest transfer arrangement further comprises a gas strut that assists movement of the backrest.
