Abstract
Abstract A fold-away table is provided for a seat in a vehicle, particularly a motorcoach. The table comprises a mounting structure disposed laterally of the seat, and a carrier structure mounted for displacement in a vertical plane between a lowered storage position and a raised use position. The carrier structure includes a pivot axis having at least one table element mounted thereon. A fold-away table of this type should be readily operable and protected from soiling. To this purpose the mounting structure is formed as a stationary vertical guide structure. The carrier is formed as a guided housing structure containing the table element and permitting it to be displaced between the use position and the storage position. The pivot axis extends substantially horizontally within the housing structure.

Claims Analysis
Total Claims: 26
Claim 1
Independent Claim
197 words
A fold-away table for a vehicle seat having a seat frame, said table comprising: a mounting base defining a stationary guide structure; means for securing said mounting base to the seat frame at a location disposed laterally from the seat with said guide structure lying in a vertical plane; a carrier defining a housing structure with an open top, said carrier being mounted on said guide structure for displacement in said vertical plane between a lowered storage position and a raised use position; a substantially horizontal pivot axis; means for mounting said pivot axis on said carrier for displacement in said vertical plane between a lowered position located within said housing structure at the lower end thereof, and a raised position at the open top of said housing structure; and at least one table element mounted on said pivot axis for pivotal movement between a folded position lying in said vertical plane, and an unfolded position extending laterally from said vertical plane, said table element when in said folded position being arranged to be lowered with said pivot axis into said housing, whereupon said carrier may then be lowered on said guide structure to said storage position.
Claim 2
Dependent Claim
197 words
A fold-away table for a vehicle seat having a seat frame, said table comprising: a mounting base defining a stationary guide structure; means for securing said mounting base to the seat frame at a location disposed laterally from the seat with said guide structure lying in a vertical plane; a carrier defining a housing structure with an open top, said carrier being mounted on said guide structure for displacement in said vertical plane between a lowered storage position and a raised use position; a substantially horizontal pivot axis; means for mounting said pivot axis on said carrier for displacement in said vertical plane between a lowered position located within said housing structure at the lower end thereof, and a raised position at the open top of said housing structure; and at least one table element mounted on said pivot axis for pivotal movement between a folded position lying in said vertical plane, and an unfolded position extending laterally from said vertical plane, said table element when in said folded position being arranged to be lowered with said pivot axis into said housing, whereupon said carrier may then be lowered on said guide structure to said storage position.
