Foldable table assembly for a passenger vehicle comprising - a table identifying a plane and a first face and a second face opposite to said first face, - a surface substantially vertical or slightly inclined and - connecting means (A, AS, T; A, AS, T, LM; A, AS, T, HW, HK) connecting said table to said surface; wherein said connecting means are such that the table can assume a first stable folded position in which said first face of the table adheres to said surface, a second stable position in which said first face is oriented upwards at a first vertical position and said plane is substantially perpendicular to said surface, and a third stable position in which the table is at a second vertical position equal or higher than said first vertical position and said plane is incident and inclined with respect to said surface with said second face facing said surface such that an acute angle (α) formed between said plane and said surface is oriented downwards; wherein said foldable table assembly has: - a flat substantially rectangular shape, and the table is hinged to said surface through a couple of arms, wherein each arm has a first end hinged to a lateral edge of the table thereby defining a first rotation axis laying substantially parallel with said first face and a second end hinged to said surface thereby defining a second rotation axis (X') laying substantially parallel with said surface; - a first edge and a second edge opposite to the first edge, both parallel with respect to said first rotation axis and wherein said surface is provided with at least a lock means suitable to receive said first edge in said second position, so as to prevent the table from rotating over said first rotation axis, and said foldable table assembly being characterized in that the table is provided with at least one through hole, close to said first edge communicating said first face with said second face, and wherein said surface is provided with at least a corresponding hook arranged over said lock means with said second rotation axis (X') arranged between said first lock means and said hook, the hook being positioned so as the table can be suspended to said hook by rotating over said first and second axis and assuming said third stable position. - a table identifying a plane and a first face and a second face opposite to said first face, - a surface substantially vertical or slightly inclined and - connecting means (A, AS, T; A, AS, T, LM; A, AS, T, HW, HK) connecting said table to said surface; wherein said connecting means are such that the table can assume a first stable folded position in which said first face of the table adheres to said surface, a second stable position in which said first face is oriented upwards at a first vertical position and said plane is substantially perpendicular to said surface, and a third stable position in which the table is at a second vertical position equal or higher than said first vertical position and said plane is incident and inclined with respect to said surface with said second face facing said surface such that an acute angle (α) formed between said plane and said surface is oriented downwards; - a flat substantially rectangular shape, and the table is hinged to said surface through a couple of arms, wherein each arm has a first end hinged to a lateral edge of the table thereby defining a first rotation axis laying substantially parallel with said first face and a second end hinged to said surface thereby defining a second rotation axis (X') laying substantially parallel with said surface; - a first edge and a second edge opposite to the first edge, both parallel with respect to said first rotation axis and wherein said surface is provided with at least a lock means suitable to receive said first edge in said second position, so as to prevent the table from rotating over said first rotation axis, and said foldable table assembly being characterized in that the table is provided with at least one through hole, close to said first edge communicating said first face with said second face, and wherein said surface is provided with at least a corresponding hook arranged over said lock means with said second rotation axis (X') arranged between said first lock means and said hook, the hook being positioned so as the table can be suspended to said hook by rotating over said first and second axis and assuming said third stable position.
