Abstract

According to the invention, a vehicle seat is provided including a seat base, a seatback and a seatback recline pivot pivotably supporting the seatback relative to the seat base for pivoting movement of the seatback relative to the seat base about the seatback recline pivot, between a full upright position and a full recline position. An armrest is provided having an upper armrest upper surface. An armrest to seatback recline pivot connection pivotably connects the armrest to the seatback recline pivot for pivoting movement of the armrest relative to the seat base about the seatback recline pivot, between an armrest full upright position and an armrest full recline position.

First claim

1 . A vehicle seat comprising:
a seat base; a seatback; a seatback recline pivot pivotably supporting the seatback relative to the seat base for pivoting movement of the seatback relative to the seat base about the seatback recline pivot, between a full upright position and a full recline position; an armrest having an upper armrest upper surface; an armrest to seatback recline pivot connection pivotably connecting the armrest to the seatback recline pivot for pivoting movement of the armrest relative to the seat base about the seatback recline pivot, between an armrest full upright position and an armrest full recline position.

2 . A vehicle seat according to claim 1 , wherein said armrest pivots with said seatback to position the armrest upper surface at a design position armrest angle of from 10° to 0° below horizontal, with said seatback in a seatback design position between the seatback full upright position and the full recline position.

3 . A vehicle seat according to claim 1 , wherein said armrest pivots with said seatback to position the armrest upper surface at a full recline armrest angle of from 0° and 20° above horizontal, with said seatback in the full recline position.

4 . A vehicle seat according to claim 1 , wherein said armrest pivots with said seatback to position the armrest upper surface at a full upright armrest angle of from 5° and 25° below horizontal, with said seatback in the full upright position.

5 . A vehicle seat according to claim 1 , further comprising a headrest assembly comprising a headrest and supports connected to a rear facing portion of the backrest.

6 . A vehicle seat according to claim 1 , further comprising:
a rotational connection of the seat base with a vehicle floor; and a rotational drive for rotating the vehicle seat relative to the seat.

7 . A vehicle seat according to claim 6 , further comprising:
a positioning system comprising an actuator, a plurality of motors and an operative connection between the actuator and the plurality of drive motors, the plurality of motors comprising said rotational drive and one seatback pivot drive for changing a pivot angle of said seatback between the seatback full upright position and the full recline position.

8 . A vehicle seat according to claim 7 , wherein the plurality of drive motors further comprise a seat base position adjustment drive adjusting a position of the seat base.

9 . A vehicle seat according to claim 7 , wherein the actuator further comprises an actuator interface connected to the armrest.

10 . A vehicle seat according to claim 7 , wherein the actuator further comprises an actuator interface provided as a computer application on a computer or mobile device and connected to the drive motors via said operative connection.

11 . A vehicle seat according to claim 7 , wherein said positioning system establishes and executes a sequenced set of specified seat movements that rotate and position the seat to predefined positions based on movements of a plurality of drive motors including said rotational drive.

12 . A vehicle seat according to claim 7 , wherein said armrest pivots independently of said seatback to position the armrest upper surface at armrest angle of from 0° and 20° above horizontal and from 0° to 25° below horizontal.

13 . A vehicle seat according to claim 12 , wherein said plurality of motors further comprises armrest pivot drive to pivot the armrest about the seatback recline pivot to select an angular position of the armrest surface of the armrest.

14 . A vehicle seat according to claim 1 , wherein said armrest pivots independently of said seatback to position the armrest upper surface at armrest angle of from 0° and 20° above horizontal and from 0° to 25° below horizontal.

15 . A vehicle seat according to claim 1 , wherein said armrest comprises an armrest upper portion with an armrest upper rear end, said armrest extending from said armrest upper rear end to an armrest upper forward end, wherein said upper armrest surface is defined by said armrest upper portion between said armrest upper rear end and said armrest upper forward end, and said armrest comprises an armrest lower portion having an armrest lower rear end, with said armrest to seatback recline pivot connection at said armrest lower rear end, and said armrest comprises a joining portion, joining said armrest upper portion with said armrest lower portion.

16 . A vehicle seatback and armrest assembly according to claim 15 , further comprising an armrest to seatback connection fixing the armrest to the seatback at a connection location, which said connection location is spaced from said armrest to seatback recline pivot connection.

17 . A vehicle seat according to claim 14 , wherein said armrest connection location is at said armrest upper rear end.

18 . A vehicle seat according to claim 15 , wherein said armrest to seatback recline pivot connection connects said armrest to said seatback recline pivot and said armrest pivots independently of said seatback to position the armrest upper surface at armrest angle of from 0° and 20° above horizontal and from 0° to 25° below horizontal.
