said lower cross beam, said bench-engaging support arms and said upright support members being integrally formed together, wherein said upright support members comprise exposed blunted upper ends, wherein said blunted upper ends are rearwardly canted.
2. The seat frame of claim 1 , wherein said blunted upper ends are rearwardly canted at a forty-five degree angle with respect to a vertical plane occupied by said lower cross beam.
3. A unitary seat frame of a seat for semi-permanent attachment to a stadium bench supported on a stadium riser, the seat frame comprising:
a lower cross beam;
bench-engaging support arms; and
upright support members having upper ends that are rearwardly canted with respect to a vertical plane occupied by said lower cross beam,
said lower cross beam, said bench-engaging support arms and said upright support members being integrally formed together as a single piece.
4. The seat frame of claim 3 , wherein said upper ends are rearwardly canted at a forty-five degree angle with respect to the vertical plane occupied by said lower cross beam.
5. The seat frame of claim 3 , comprising at least one angled brace integrally connected to one of said upright support members and said lower cross beam.
6. The seat frame of claim 3 , comprising at least one mounting receptacle positioned on said lower cross beam.
7. The seat frame of claim 3 , wherein the seat frame is devoid of an upper cross beam connecting upper portions of said upright support members.
8. The seat frame of claim 3 , comprising a lower prong integrally connected to one of said bench-engaging support arms through an intermediate upright, wherein a bench retention cavity is defined between said one of said bench-engaging support arms and said lower prong, and wherein the stadium bench is configured to be compressively sandwiched between said one of said bench-engaging support arms and said lower prong.
9. The seat frame of claim 3 , wherein the seat frame is mounted to the stadium bench by urging said seat frame into the stadium bench through a rear end of the stadium bench.
10. An open-backed seat frame for semi-permanent attachment to a stadium bench, the seat frame comprising:
a lower cross beam;
first and second support arms positioned having each a front end and a rear end, said front end of said first and second support arms including forward hooks configured to engage the stadium bench to which said seat frame is attachable; said rear ends of said first and second support arms positioned proximate to opposite ends of said lower cross beam;
first and second upright support members positioned proximate to opposite ends of said lower cross beam, said upright support members having an upper portion and a lower portion, wherein a substantially open space is defined between said upper portions of said first and second upright support members, said first and second upright support members each including an upright bar and a rounded upper end formed by a bend in said upright bar, and wherein said rounded upper ends are coplanar with a substantially vertical plane occupied by the lower cross beam;
wherein said support arms, upright support members, and lower cross beam are integrally formed; and
mounting receptacles configured to receive a strap for securing said seat frame to said stadium bench, said mounting receptacles located on said forward hooks and on said rear end of said first and second support arms.
11. The seat frame of claim 10 wherein said first upright support member is oriented substantially perpendicularly to said first support arm, and said second upright support member is oriented substantially perpendicularly to said second support arm.
12. The seat frame of claim 10 further comprising a flexible backrest, said flexible backrest spanning at least a distance between said first and second upright support members and including an interior cavity that accepts at least a portion of said first and second upright support members, wherein at least a portion of said open space is covered by said flexible backrest.
13. The seat frame of claim 10 wherein at least some of said mounting receptacles are substantially co-planar with a substantially horizontal plane occupied by said first and second support arms.
14. The seat frame of claim 10 further comprising a seat cushion configured to be removably attached to said seat frame, said seat cushion including spaced loops, each spaced loop configured to be looped around one of said forward hooks.
15. The seat frame of claim 14 wherein said spaced loops are configured to attach to at least some of said mounting receptacles.
16. A unitary seat frame of a seat for semi-permanent attachment to a stadium bench supported on a stadium riser, the seat frame comprising:
a lower cross beam;
bench-engaging support arms having each a front portion and a rear portion, said front portion of said bench-engaging support arms including forward hooks configured to engage the stadium bench to which said seat frame is attachable, said forward hooks comprising a lower prong integrally connected to one of said bench-engaging support arms through an intermediate upright; said rear portion of bench-engaging support arms positioned proximate to opposite ends of said lower cross beam;
upright support members that connect to one or both of said lower cross beam and/or said bench-engaging support arms, said upright support members oriented substantially perpendicularly to said bench-engaging support arms, said upright support members having an upper portion, a midpoint and a lower portion;
an open area defining a vertical plane between said upper portions of upright support members that is devoid of any cross beams;
mounting receptacles configured to receive a strap for securing said seat frame to said stadium bench, said mounting receptacles located on said forward hooks and on said rear end of bench engaging support arms, wherein at least some of said mounting receptacles are substantially co-planar with a substantially horizontal plane occupied by said bench-engaging support arms;
said upright support members each including an upright bar and a rounded upper portion formed by a bend in said upright bar, and wherein said rounded upper ends are coplanar with a substantially vertical plane occupied by the lower cross beam.
