A user engagable cushioned section 14 is locatable on a user facing side 16 of the support structure 13 and the support structure 13 is shaped and dimensioned to receive at least a portion 21 of the cushioned section 14 such that the cushioned section comprises at least one localised area of increased thickness 15.
Claims16
A vehicle seat comprising a seat base and a backrest portion, wherein the backrest portion comprises:
- a support structure;
- a user engagable cushioned section locatable on a user engagement side of the support structure;
- wherein the support structure is shaped and dimensioned to receive at least a portion of the cushioned section such that the cushioned section comprises at least one localised area of increased thickness located in the area of the shoulder of a user when the user is lying on their side, wherein the support structure is shaped to define a cavity, the cavity defining an opening thereinto from the user facing side of the support structure, at least a portion of the cushioning section extends into the cavity of the support structure to form the localised area of increased thickness, the cavity being shaped and dimensioned such that it does not extend beyond the rearward side of the backrest portion and the presence thereof does not increase the depth of the support structure, and therefore does not increase the overall depth of the backrest portion, and wherein the top and bottom longitudinal end of the cavity is a tapered end such that the cavity tapers away from the user facing side of the backrest portion;
- and
- wherein the cushioned section comprises a stepped profile when viewed in cross section in the width-wise dimension, the cushioned section comprising a first portion of cushioned section and a second portion of cushioned section, the second portion cushioned section extending from the first portion of cushioned section, such that said second portion is seated further rearwardly into the cavity, the second portion being shaped to conform to the shape of a rearward portion of the cavity, the first and second portions of the cushioned section together forming a generally T-shape cross section.

A method of manufacturing a vehicle seat comprising the steps of:
- providing a seat base and a backrest portion, the backrest portion comprising a support structure shaped and sized to receive at least a portion of a cushioning section;
- forming a cushioning section having a localised area of increased thickness corresponding to the area of the shoulder of a user when the user is lying on their side;
- fitting the cushioned section to a user facing side of the support structure such that at least a portion of the cushioning section is received by the support structure;
- and
- shaping the support structure to define a cavity, the cavity defining an opening thereinto from the user facing side of the support structure, at least a portion of the cushioning section extends into the cavity of the support structure to form the localised area of increased thickness, the cavity being shaped and dimensioned such that it does not extend beyond the rearward side of the backrest portion and the presence thereof does not increase the depth of the support structure, and therefore does not increase the overall depth of the backrest portion, and;
- tapering the top and bottom longitudinal end of the cavity such that the cavity tapers away from the user facing side of the backrest portion;
- and
- providing the cushioned section with a stepped profile when viewed in cross section in the width-wise dimension, the cushioned section comprising a first portion of cushioned section and a second portion of cushioned section, the second portion cushioned section extending from the first portion of cushioned section, such that said second portion is seated further rearwardly into the cavity, the second portion being shaped to conform to the shape of a rearward portion of the cavity, the first and second portions of the cushioned section together forming a generally T-shape cross section.
