Claim 8

A stowable seat back tray table for pivotal support on a pair of support arms pivotally attached to a seat back, comprising: a first generally U-shaped table section defined by a first generally rectangular planar panel member having a pair of guide and support arms extending outwardly in parallel relation and in a plane therewith, and upper and lower parallel planar surfaces, said first table section pivotally attached to a pair of support arms for pivoting between a generally vertical stowed position and a horizontal operative position and having a first planar support surface defined by said upper planar surface; and a second generally rectangular planar panel member slideably mounted on said support arms of said first member and having a second planar support surface selectably positionable to a stowed position overlying said first support surface and an operative position providing an extension of said first support surface; and extensible drink container well formed in said first panel member and comprising an aperture through said panel, and a generally U-shaped hanger pivotally supported at its ends in said aperture for pivoting to a support position under the force of gravity, and biased by a forward edge of said second support tray member to a retracted stowed position.

Claim 9

A stowable seat back tray table according to claim 6 wherein said second tray table member includes channel means for receiving said arms for slideable support thereof.

Claim 10

A stowable seat back tray table according to claim 7 wherein: said channel means comprises a pair of outwardly directed open ended channels extending along side edges of said second second panel member; an elongated slot formed in and extending along each of said slots; and a projecting lug on each of said arms extending into each of said slots for limiting the sliding movement of said second panel relative to said first panel.

Claim 11

A stowable seat back tray table according to claim 8 wherein: said second panel member comprises spaced upper and lower sheets forming a substantially hollow core.

Claim 12

A stowable seat back tray table for pivotal support on a pair of support arms pivotally attached to a seat back, comprising: a first generally U-shaped table section defined by a first generally rectangular planar panel member having a pair of guide and support arms extending outwardly in parallel relation and in a plane therewith, and upper and lower parallel planar surfaces, said first table section pivotally attached to a pair of support arms for pivoting between a generally vertical stowed position and a horizontal operative position and having a first planar support surface defined by said upper planar surface; a second generally rectangular planar panel member having channel means extending along opposed side edges thereof for receiving said arms for slideable support thereof, and having a second planar support surface selectably positionable to a stowed position overlying said first support surface and an operative position providing an extension of said first support surface; and a pair of extensible drink container wells formed in said first panel member, each comprising an aperture through said panel and an adjacent recess, and a generally U-shaped hanger pivotally supported at its ends in said aperture for pivoting downward to a support position under the force of gravity, and biased by a forward edge of said second support tray member to a retracted stowed position within said adjacent recess.

Claim 13

A stowable seat back tray table for pivotal support on a pair of support arms pivotally attached to a seat back, comprising: a first generally U-shaped table section defined by a first generally rectangular planar panel member having a pair of guide and support arms extending outwardly in parallel relation and in a plane therewith, and upper and lower parallel planar surfaces, said first table section pivotally attached to a pair of support arms for pivoting between a generally vertical stowed position and a horizontal operative position and having a first planar support surface defined by said upper planar surface; a second generally rectangular planar panel member having channel means extending along opposed side edges thereof for receiving said arms for slideable support thereof, and having a second planar support surface selectably positionable to a stowed position overlying said first support surface and an operative position providing an extension of said first support surface; and a pair of extensible drink container wells formed in said first panel member, each comprising an aperture through said panel and an adjacent recess, and a generally U-shaped hanger pivotally supported at its ends in said aperture for pivoting downward to a support position under the force of gravity, and biased by a forward edge of said second support tray member to a retracted stowed position within said adjacent recess.
