Abstract

A seat armrest and process of manufacturing same, including an armrest frame member and three shell members located around the frame member. All of the shell members have a depressed central portion and outer rim portions and one of the shell members is so sized so that it is slideable into one of the other shell members which is in turn connected to the arm frame member. The third shell member is then slideable over the other two combined shell members, and the inner wall of that shell member and the outer wall of the adjacently located shell member form a pocket in the seat armrest. A panel is also provided which is easily attachable to or removable from the armrest.

Claims

1. An armrest for a seat comprising a first shell, said first shell comprising a central substantially flat portion with a flange extending outward therefrom, a second shell, said second shell comprising a central substantially flat portion with a flange extending outward therefrom, the flanges of said first and said second shells being formed so that the flange of one shell fits into the flange of the other shell, the flanges of said first and said second shells being interconnected with the flange of one shell fitting into the flange of the other shell to form a combined unit comprising said first and second shells, and a third shell member, said third shell member having a central substantially flat portion with a flange extending outward therefrom, the flange of said third shell being formed to be slidable over the unit formed by said first and said second shells, the flange of said third shell being connected to the combined unit formed by said first and second shells after the flange of said third shell has been slid over the unit formed by said first and said second shells.

2. The armrest for a seat of claim 1 wherein the width of the flange of said third shell is greater than the width of the combined unit comprising said first and second shells.

3. The armrest for a seat of claim 2 wherein the inner surface of said third shell and the outer surface of the combined unit comprising said first and second shells forms a pocket.

4. The armrest for a seat of claim 3 wherein the flange of said third shell has elongated aperture.

5. The armrest for a seat of claim 4 wherein the aperture in the flange of said third shell comprises elongated slot extending through the flange.

6. The armrest for a seat of claim 5 wherein the width of the slot located in the flange of said third shell is substantially equal to the width of the pocket formed by the inner surface of said third shell and the outer surface of said combined unit comprising said first and second shells.

7. A process of manufacturing a seat armrest comprising the steps of forming a first shell having a central substantially flat portion with a flange extending outward therefrom, forming a second shell having a central substantially flat portion with a flange extending outward therefrom, during the steps of forming said first and second shells forming the flange of one of said first or second shells so that the flange of one of said first or second shells so that it is insertable into the flange of the other of said first or second shells, inserting one of the flanges of said first or second shells into the flange of the other of said first or second shells connecting them together to form a combined unit comprising said interconnected first and second shells forming a third shell having a central substantially flat portion with a flange extending outward therefrom, during the process of forming said third shell forming the flange of said third shell so that it will be slidable over the combined unit formed by the interconnected first and second shells, sliding the flange of said third shell over the combined unit formed by said first and second shells and connecting the flange of said third shell to the combined unit formed by said first and second shells.

8. The proces of manufacturing a seat armrest of claim 7 including the step of providing a slot in a portion of the flange of said third shell.
