Table unit

A table unit for seats in vehicles, especially airplane seats, includes a first table element ( 10 ) provided with the functions of a table, and a second table element ( 12 ) provided with at least one other table function. Both table elements ( 10, 12 ) can be rotated relative to each other about a first pivotal axis ( 14 ) by a hinge ( 18, 20 ), and can be fixed in a predetermined position. Various table functions can be integrated in a single table unit since both table elements ( 10, 12 ) can be rotated about a pivotal axis ( 16 ) by another joint ( 20, 22 ), and can be fixed in a predetermined position. The possible table surface and position thereof can be varied in such that certain table functions are protected and service personnel can have access to them.
