Stadium seat

In a stadium chair assembly,

• a. a chair seat and a chair back having hinged interconnection allowing the back to swing between upright extended position, and horizontal collapsed position relative to the seat, there being stops to limit swinging of the back,
• b. the seat having opposite sides and a sidewardly elongated front stretch,
• c. U-shaped holder means having pivotal attachment to said front stretch to swing between upwardly collapsed position extending beneath said front stretch, and downwardly extended position, the holder means including arm means spaced sufficiently below said front stretch in said downwardly extended position as to project closely beneath a stadium seat for retaining the chair assembly thereto,
• d. torsion spring means operately connected between said front stretch and said holder means, and yieldably urging the holder means toward said upwardly collapsed position, said front stretch being tubular and said torsion spring means having torsion windings received within said tubular stretch and two terminals, one terminal confined within the stretch against rotation and the other terminal attached to the arm means exteriorly of said stretch,
• e. and legs pivotally attached to said chair seat allowing leg swinging between downwardly projecting extended positions and horizontally extending collapsed positions adjacent the underside of the seat, there being stop shoulders to limit said swinging, the legs and holder means having mutually non-overlapping swing paths.
