  • Publication number: 20070200409
    Abstract: A seat assembly comprises a seat back and a seat base. The seat back is pivotable on a pivot pin assembly with respect to the seat base between a full up position and a down position. A seat back bracket is connected to the seat back and a seat base bracket is connected to the seat base. The seat base bracket has a stop and the seat back bracket has a stop, and the stops engage one another to restrict rotation of the seat back bracket with respect to the seat base bracket at the full up position. In accordance with another aspect the seat back bracket and seat base bracket each have corresponding unitary projections which cooperate to define a bearing surface which directly receives the pivot pin end caps.

  • Patent number: 6854216
    Abstract: A self-storing telescoping seat assembly is disclosed which comprises rows of seating movable between a retracted position where the rows of seating are generally stacked on top of one another, to an extended position and a handrail assembly affixed to a corresponding row of seating in a single assembled position with respect to that row. The handrail assembly stays in the single assembled position as the rows move between the extended position and the retracted position. The handrail assembly can have a top handrail and a lower handrail which cooperate to form an opening, and the opening is preferably adapted to receive the front face of a deck of a row of seating when the rows of seating are in the retracted position. A front face can be formed by the rows of seating in the retracted position, and the handrail assembly has a post which preferably extends in front of the front face when the rows of seating are in the retracted position.

  • Patent number: 6354041
    Abstract: A deployable telescopic seating structure employs a backstop arrangement to prevent users and operators from coming into contact with structure that may cause injury, such as interengaging metal elements that limit the extent of deployment The backstop portions are arrangement in the aisle region of the telescopic seating structure and have an overall height that is responsive to the height of one seating level above another, or in another embodiment, to the difference between such height and an intermediate step. The backstop arrangement has an engagement portion with an edge portion that precludes a discontinuity on the walking surface of tile seating structure. Structural integrity and strength of the riser portion is enhanced by forming same as a multi-fascia structure having a reinforcing corrugation therebetween. A curved back portion along the lowermost edge serves as a termination and additionally adds strength to the backstop arrangement.

  • Patent number: 6324790
    Abstract: A deployable seating arrangement employs a plurality of seating level members that are arranged in sequentially elevated relation to one another. When the deployable seating arrangement is in an undeployed state, the seating level members are disposed substantially directly beneath one another in stacked relation. When in a deployed condition, each seating level member is disposed beneath and forward of an immediately superior seating level member in stepped relation. Each of the seating level members has associated therewith a plurality of L-shaped frame elements that are formed of vertical and horizontal portions. A roller is installed at the upper end of the vertical portion for engaging with the underside of the horizontal portion of an immediately superior seating level member. A drive arrangement having a wide track motor drive urges the seating level members, which are installed on a plurality of respective wheeled frame arrangements, into deployed and undeployed states.

The backstop portions are arranged in the aisle region of the telescopic seating structure and have an overall height that is responsive to the height of one seating level above another, or in another embodiment, to the difference between such height an an intermediate step. The backstop arrangement has an engagement portion with a flange element that extends transversely therefrom and which engages with a top surface of the seating level. Preferably, the engagement portion forms a forwardmost edge termination. A fastening portion is arranged intermediate of the engagement portion and the riser portion of the backstop member.

  • Patent number: 6185875
    Abstract: A telescopic seating system with aisle rails in the form of discrete and lightweight uprights. A telescopic seating system, such as a bleacher system or a platform seating system, is equipped with a series of uprights, which are easily movable to positions whereby the seating system can be retracted. The railing system includes discrete lightweight and movable uprights, each having a single closed-loop upper section. The noses of the decks upon which rows of seating are mounted have sockets which receive the lower end of each upright and support the uprights in the aisles of the seating system. Because the uprights are lightweight, discrete and easily moveable, the tendency to use the seating system without installing the handrails is reduced or eliminated.

  • Patent number: 6076306
    Abstract: A railing system for a telescopic seating arrangement, such as bleacher systems and platform seating systems. The railing system includes discrete lightweight and readily stowable uprights, each having a single closed-loop upper section. Brackets carried by the nose of decks receive a plate affixed to the lower end of each upright. The brackets which support the uprights have a low profile so that the seating system is readily useable if the uprights are not installed. The lightweight and easily stowed uprights of this railing system eliminate the factors which lead to use of a seating system without handrails.
