摘要： A seat is mounted on an L-shaped trolley frame which moves vertically along two spaced rails of a seat support frame. An airspring cushion member is fixedly mounted adjacent the seat support frame and has one end interconnected with the movable trolley to cushion the downward movement of the seat. The airspring cushion has a charging valve for pressurizing the airbag and a manually operable air bleeding device for selectively relieving air pressure from the cushion to permit an occupant of the seat to select an appropriate pressure and cushioning effect. After the proper cushioning rate has been obtained, a manually adjustable height adjustment device may be used to move the seat vertically into a comfortable operating position.

摘要： A seat in a mass transit vehicle, such as a bus or subway car, extends lengthwise from the vehicle wall toward the aisle. The seat is supported from below by a cantilevered supporting shell comprising a trough-shaped structural skin and a tubular frame without diagonal bracing. The trough-shaped skin has an open top and an open end at the vehicle wall.

摘要： A torsion bar suspension system for a seat. Structure is provided for twisting the torsion bar to preload it. Structure is also provided for adjusting the height of the seat without changing the preload in the torsion bar, and this is accomplished by pivoting the preloading structure, with the torsion bar, about the axis of the torsion bar.

摘要： A seat for a mass transit vehicle has a metal frame with a back portion including side bars and a top bar. A back shroud for the seat is slidably mounted on the side bars. Hook-shaped marginal portions on the shroud engage the bars and hold the shroud against movement in upward, sideward, frontward and rearward directions. Movement of the shroud in a downward direction is prevented by a pair of fasteners, located in recesses in a downwardly depending portion of the shroud, and engaging a lower bar of the seat frame.

摘要： A seat for a vehicle operator includes an occupant-supporting portion, a back and an armrest. The armrest is pivotable through a vertical plane between a horizontally extending, arm-supporting position and an upwardly extending position alongside the seat back. The armrest is also pivotable, in response to a predetermined outwardly directed force against the armrest, through a horizontal plane, between the above-described arm-supporting position and a position in which the armrest extends rearwardly from the seat back. Structure is provided which normally urges the armrest from its rearwardly extending position to a downwardly extending position alongside the seat.

摘要： A seat in a mass transit vehicle is supported by a shell cantilevered from a side wall of the vehicle interior. The shell comprises a pair of horizontally extending frame members and a trough-shaped structural skin. A blower is mounted within the housing defined by the skin to blow conditioned air through an opening in the bottom of the skin. A deflector is rotatably mounted on the outside of the skin. Vanes on the deflector deflect air blown through the opening in a direction determined by the position to which the deflector has been rotated.

摘要： A seat for a mass transit vehicle such as a bus. The seat has a cushioned grab bar at the top of the seat back. The grab bar comprises a round inner tubular member of steel and an outer layer of resilient cushioning material such as polyvinyl chloride integrally bonded to the inner member to prevent slippage of the outer layer relative to the inner member. Where the grab bar is joined to the seat, any exposed edges on the frame or shell of the seat are covered by the cushioning material of the grab bar.

摘要： A pedestal supports a base frame above which is a seat frame resiliently mounted on the base frame with four energy absorbing devices constituting the sole connection between the base frame and the seat frame. Each energy absorbing device comprises a block of rubber bonded to upper and lower metal plates extending from the block in opposite directions and connected by respective brackets to the seat frame and the base frame respectively. Each block has a bending or flexing surface inclined upwardly and outwardly toward the seat frame.

摘要： A metal seat pan is placed inside a rotational casting mold to define part of a rotational casting cavity into which is introduced rotationally castable material for forming a flexible plastic seat cover. A rotational casting operation produces a closed, hollow seat cushion shell defined by the seat pan and the flexible plastic cover. Foaming ingredients are introduced into the hollow shell to form a resilient foamed plastic interior. The resulting seat cushion is monolithic, without seams or joints and has no removable parts or mechanically joined components which will come apart from each other.
