This invention r elates to seat'and aislelight ing, =1 r.
An object of the invention is to provide a-structure for providing a bright illuminating light for w corporation of New Jersey 7 .Ae ucaumiiu h 16,1950, SerialNo.150,084 I z'claiins.

Thebox 22 is provided along the floor of the aisle in a vehicle while providing 5 its top Wall with spaced flanges 25 running lona subdued light above the seat and preferably ilgitudinally of the box and inclined upwardly and luminating a sign. Yet another object is to prooutwardly to receive the angular flange I8 of vide a structure in which a bright light is shelplate I6. With this structure, it will be noted tered below an arm seat and well under the same that the box 22 and the aperture 23 are thus so as to present no direct beams in a direction 10 spaced well inwardly of the plate 2I so that the above the seat while at the same time directing a light rays from the bulb are shielded from persons subdued light outwardly to a sign substantially Walking along the aisle while, at the same time, flush with the outer surface of the seat to illumithe bulb rays are utilized for illuminating the hate the sign and provide a subdued light for the sign above and giving a soft or reflected light upper portion of the aisle.

The sign may set out a name or seat number or other desired indicia.
We prefer to employ a plate IB having a straight upper portion and an angular inwardly and downwardly inclined lower flange portion I8, as shown best in Fig. 3. The upper straight portion which bears the sign recesses I7 is aligned with a recess i9 in the outer plate of the arm rest frame so that the sign plate is visible from the outer side of the arm rest. A flange 20 is employed and preferably secured to the plate 2I of the arm rest frame I5, as shown best in Fig. 3.
At the base of the arm rest I5 and inwardly of the side plate 2|, we provide an illumination box the purpose of illustrating the invention, it will be understood that the details of structure may be varied widely by those skilled in the art without departing from the spirit of our invention.
1. In a seat structure having a base, a seat thereon, and an arm rest supported upon the side of the seat and terminating in a line generally aligned with the bottom portion of the seat, said arm rest having an opening therein, a light-transmitting sign-bearing plate closing said opening and forming a portion of the side wall of said arm rest, said plate having its lower edge terminating near the bottom of said arm rest, a casing secured to the lower edge portion of said arm rest and providing an illumination box, said casing being slotted along its upper side to receive the lower edge of said light-transmitting plate, said casing having its lower side provided with an illumination opening for the projection of light rays below said arm rest, and a light bulb mounted in said illumination box for projecting rays downwardly below said arm rest and upwardly through the plate forming a panel in said arm rest.
