ABSTRACT:
A modular unit for assembling seats comprises a plurality of elements which are spatially complementary and can be grouped together about an axis. The elements can be associated with respective portions of the seat to be produced and are rigidly connected together by a screw which can extend through a longitudinal hole formed jointly by grooves in the elements. The rotation of the screw causes a transverse sliding of two locking elements having inclined surfaces which cooperate with respective sloped portions of the elements in order to urge the elements into a state in which they are assembled about the axis. The elements may be of integral construction with portions of the seat such as a seat portion, an armrest portion or a leg portion.
