Abstract

A vehicle seat comprising a guiding device comprising a first articulation portion and a second articulation portion, the first articulation portion has a first articulation surface, the second articulation portion has a second articulation surface, a first stop element and a second stop element, a first backrest, a second backrest comprising a first flange and a second flange, the first flange has a first bore cooperating with the first articulation surface, the second flange has a second bore cooperating with the second articulation surface, the second bore has a circular portion and a notch, the notch of the second bore is configured to allow the passage of the second stop element through the notch.

First claim

The invention claimed is:

1 . A vehicle seat, configured to accommodate at least two users, the vehicle seat comprising:
a first support and a second support intended to be connected to a vehicle chassis, a guiding device comprising:
a first support portion and a second support portion, the first support portion cooperates with the first support and the second support portion cooperates with the second support,
a first articulation portion and a second articulation portion, the first articulation portion has a first articulation surface, the second articulation portion has a second articulation surface,
a first backrest comprising a first backrest structure, the first backrest structure is pivotably mounted relative to the first support and the second support around an axis of rotation extending in a transverse direction, a second backrest pivotably mounted around the axis of rotation on the guiding device, the second backrest comprises a second backrest structure, the second backrest structure comprises:
a first flange having a first bore, the first bore cooperates with the first articulation surface, and
a second flange having a second bore, the second bore cooperates with the second articulation surface,
wherein the second articulation portion further has a first stop element and a second stop element, the second articulation surface is arranged between the first stop element and the second stop element along the transverse direction, the first stop element prevents the movement of the second flange relative to the guiding device along the transverse direction in a first direction, the second stop element prevents the movement of the second flange relative to the guiding device along the transverse direction in a second direction, opposite the first direction, and the second bore has in cross-section perpendicular to the axis of rotation a circular portion and a notch, the notch of the second bore is configured to allow the passage of the second stop element through the notch by translation along the transverse direction.

2 . The vehicle seat of claim 1 , wherein the second articulation portion is configured to pass through the first bore.

3 . The vehicle seat of claim 2 , wherein the first bore has in cross-section perpendicular to the axis of rotation a first circular portion and a first notch, the circular portion of the second bore forming a second circular portion and the notch of the second bore forming a second notch, and the first notch is configured to allow passage of the first stop element and the second stop element through the first notch by translation along the transverse direction.

4 . The vehicle seat of claim 3 , wherein the first circular portion has a first diameter and the second circular portion has a second diameter, the first diameter is substantially equal to the second diameter.

5 . The vehicle seat of claim 3 , wherein the first stop element is a first stud forming a protrusion relative to the second articulation surface, the second stop element is a second stud forming a protrusion relative to the second articulation surface, the first stud is angularly aligned with the second stud around the axis of rotation, and the first notch is angularly aligned with the second notch around the axis of rotation.

6 . The vehicle seat of claim 5 , wherein the first stud has a chamfer configured to position and closely maintain the second flange between the first stud and the second stud by rotating the second backrest relative to the guiding device around the axis of rotation after insertion of the second stud through the second bore.

7 . The vehicle seat of claim 1 , wherein the guiding device comprises a main portion, the main portion comprises the first articulation portion and the main portion is metallic and a retaining portion, the retaining portion comprises the second articulation portion and the retaining portion is made of plastic and molded onto the main portion.

8 . The vehicle seat of claim 1 , wherein the first backrest is attached to the guiding device and the guiding device is pivotably mounted around the axis of rotation relative to the first support and the second support.

9 . The vehicle seat of claim 8 , wherein the guiding device comprises a guide member cooperating with the first support portion, a guide shaft comprising the second support portion, a first hinge portion and a second hinge portion, and the guide shaft is rigidly attached to the guide member by the first backrest structure.

10 . The vehicle seat of claim 1 , wherein a first hinge portion and a second hinge portion are arranged between the first support portion and the second support portion in the transverse direction.

11 . A vehicle comprising at least one vehicle seat according to claim 1 .
