Abstract

A vehicular seat, such as an aircraft seat, comprising a seat bottom portion, a seat back portion mounted for pivotal movement about a selected pivot axis and having a predetermined upright position, a tray assembly including a tray member and leg means mounted for pivotal movement about the pivot axis from a first storage position to a second in use position, the tray member mounted on the leg means and having a horizontal in use position and a storage position whereat the tray defines the rear surface of the seat back portion, the leg menas having first and second segments joined by a bend having a predetermined angle, and the leg means being selectively configured so that when the tray assembly is in the in use position the bend will be proximate the seat back and one of the segments will be substantially horizontal whereby the tray assembly will not interfere with the lateral leg movement of a user of the tray assembly.

Claims

1. A vehicular seat comprising

a seat bottom,

a seat back mounted for pivotal movement about a selected pivot axis having a selected upright position,

a tray assembly including

a pair of legs mounted on either side of said seat back for pivotal movement about said seat back pivot axis from a storage position to an in-use position,

said legs each including a first portion extending upwardly from said seat back pivot axis and a second portion joined at one end via a bend to the top of said first portion,

a tray,

means for mounting said tray on the other end of said second portions for selected pivotal displacement relative thereto from a first position wherein the bottom surface of said tray defines a portion of the back surface of said seat back when said legs are in the storage position to a second horizontal position when said legs are in the in-use position,

said bends having an angle selected so that said second portion of each of said legs will be substantially horizontal when said legs are in the in-use position and said legs being selectively configured so that when said seat back is in said upright position pivotal displacement of said legs about said seat back pivot axis from the storage position to the in-use position will displace said bends from a location substantially forwardly spaced from the back surface of the seat back to a location proximate the back surface and will displace the other end of said second portions from a location proximate the back surface of said seat back to a location substantially rearwardly spaced from the back surface.

2. A vehicular seat according to claim 1, wherein said first portion of said legs extends substantially vertically upwardly when said legs are in the storage position.

3. A vehicular seat according to claim 1, wherein said seat bottom includes a horizontal occupant supporting portion and said seat back pivot axis is substantially above said horizontal portion.

4. A vehicular seat according to claim 1, wherein said seat back includes two selectively configured side cut outs and a selectively configured back cut out for receiving said tray assembly legs and tray, respectively, when said tray assembly is in said storage position.
