Abstract

A suspension system for a backrest of a vehicle seat, wherein the suspension system comprises:
a main support, the main support has a main plate, an ancillary support, the ancillary support has an ancillary plate, the ancillary plate has a central portion extending along the extension of the main plate in an elevation direction, and a structural core extending in the elevation direction between an upper structural end and a lower structural end, the upper structural end and the lower structural end are intended to be attached to a frame, the main support and the ancillary support are attached to the structural core.

First claim

The invention claimed is:

1 . A suspension system for a backrest of a vehicle seat, wherein the suspension system comprises:
a main support, the main support has a main plate, the main plate extends along a transverse direction between a first-side main edge and a second-side main edge, an ancillary support, the ancillary support has an ancillary plate, the ancillary plate has a central portion extending along the extension of the main plate along an elevation direction perpendicular to the transverse direction, and a structural core extending along the elevation direction between an upper structural end and a lower structural end, the upper structural end and the lower structural end are intended to be attached to a frame, the main support and the ancillary support are attached to the structural core.

2 . The suspension system of claim 1 , wherein the structural core comprises at least one wire having a cross-section comprised between 10 square millimeters and 100 square millimeters.

3 . The suspension system of claim 2 , wherein:
the structural core comprises a first-side wire portion and a second-side wire portion, the first-side wire portion and the second-side wire portion are separated from one another in the transverse direction by a distance of at least 20 centimeters, and the main support is attached to the first-side wire portion and to the second-side wire portion.

4 . The suspension system of claim 3 , wherein:
the main support is attached to the first-side wire portion at the first-side main edge, and the main support is attached to the second-side wire portion at the second-side main edge.

5 . The suspension system of claim 3 , wherein the structural core comprises a lower-wire portion extending along the transverse direction at the lower structural end between the first-side wire portion and the second-side wire portion, so that the first-side wire portion, the lower-wire portion and the second-side wire portion form three successive parts of a single wire.

6 . The suspension system of claim 1 , wherein:
the main plate extends along the elevation direction between a main upper edge and a main lower edge, the central portion extends along the elevation direction between a central upper edge and a central lower edge, and the central lower edge extends opposite the main upper edge.

7 . The suspension system of claim 6 , wherein:
the ancillary plate further has a first-side lateral portion, the first-side lateral portion extends along the transverse direction from the central portion to a first-side outer edge, located beyond the first-side main edge.

8 . The suspension system of claim 7 , wherein:
the first-side lateral portion extends along the elevation direction to a first-side lower edge, and the first-side lateral portion has a first-side inner edge extending opposite the first-side main edge.

9 . The suspension system of claim 1 , wherein:
the structural core has an upper attachment portion, a lower attachment portion and a holding portion, the upper attachment portion is arranged at the upper structural end and intended to be attached to the frame, the lower attachment portion is arranged at the lower structural end and intended to be attached to the frame, the holding portion extends along the elevation direction between the upper attachment portion, and the lower attachment portion, and the main support is attached to the holding portion.

10 . A backrest comprising the suspension system according to claim 9 and the frame, wherein the suspension system is held on the frame by the structural core.
