A mechanism for raising and lowering an armrest for a seat includes an armrest, a rotatable hub, and an actuating linkage between the armrest and the hub, the rotatable hub having a cam that operates the actuating linkage to raise the armrest wherein the cam can rotate through a first angle of rotation where the actuating linkage is not operated a second angle of rotation where the actuating linkage is operated. The cam can rotate through a third angle of rotation where the actuating linkage is not operated, this angle being different to the first angle of rotation. The cam is torsionally linked to the rotation of a seat member.

A compact recliner mechanism for use in theater seating units is provided that allows the seat to move linearly as the seating unit moves from the closed position to the reclined position. The mechanism has a back bracket coupled to the seat plate and base plate with a linkage that moves a projected point representing the top of the back of the seating unit downwardly in vertical plane as the seating unit moves from the closed position to the reclined position. In other aspects, the seating unit has an armrest linkage coupled between the seat plate and the back that maintains an armrest lever at a horizontal orientation. Additionally, in some aspects, the base plate of the seating unit may have an adjustment feature that limits recline of the seating unit, to accommodate theater seating with different riser dimensions, and/or legs with an adjustment feature to level the seating unit on existing theater floors.

A method and apparatus include attaching a lighted cup holder to a seating arrangement. The lighted cup holder includes a cup holder body and a light-producing light source, with the cup holder body being attached to the seating arrangement and having a cup receptacle therein, the light-producing source being disposed within the cup receptacle for illuminating the receptacle. A light-sensitive element operatively connected to the light source selectively controls production of light by the light source in such a manner that illumination of the cup holder is provided only under conditions where visibility is reduced to the point that it becomes difficult to locate the cup holder. The light-sensitive element is mounted on a master lighted cup holder and controls illumination of the master lighted cup holder and one or more slave lighted cup holders operatively connected to the master lighted cup holder.

A method for assembling a modular auditorium and modular auditorium. The method includes providing a plurality of nominal inventory portions. Each nominal inventory portions includes a prefabricated base portion, and a prefabricated tier section for assembly to the base portion. The prefabricated base portion is positioned on a ground surface of a public performance space. The prefabricated tier section is fastened to the prefabricated base portion to form a self supporting modular auditorium structure that does not require lateral support from a building structure other than the ground surface.
