Abstract: A longitudinal seat assembly for three or more occupants and comprising a plurality of seats mounted on a unitary supporting and seat frame. The unitary frame has horizontally and vertically disposed portions, and the vertically disposed portion terminates substantially below the seat tops.

Abstract: A walk-over seat has a base with a pair of side members and a seat back which may be moved between the front and rear ends of the seat. The seat back is connected to the upper ends of two elongated links on each side of the seat back. Each link has a lower end mounted for pivotal movement about a horizontal axis between frontwardly and rearwardly extending positions. Each link is engaged by a respective latching member when the link is in one of its positions. Structure is provided to transfer to the side members of the seat the load exerted against a latching member by the link when the seat back is impacted or hit from behind, to prevent the latching member from being sprung or bent out of position. The latching member has a special configuration to accommodate differing dispositions and mountings of the latching member and the link it engages.

Abstract: A seat has a frame including a back portion. A seat cushion, a back cushion and a back shroud are all mounted on the frame. Attached to the rear of the back cushion, near the bottom thereof, are a pair of clips which hookingly engage a pair of tabs on the frame and mount the back cushion for vertical sliding movement on the tabs. Attached to the rear of the back cushion, near the top thereof, is a bracket which is attached by a fastener to a cross member at the top of the frame's back portion. The operation of fastening the bracket to the cross member raises the back cushion in vertical sliding movement on the tabs.

Abstract: A wheelchair wheel is received and restrained in a device mounted on the support for a folding seat in a mass transit vehicle. The wheel is held in a restrained position by a pair of pivotal jaws normally urged to an open position but actuated to a closed position in response to the entry of a wheelchair wheel into the space between the open jaws. The jaws are opened to face the wheel by manipulation of a manually operated handle.

Abstract: 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.

Abstract: A seat cushion is readily installed onto and removed from a seat frame utilizing structure which disengages the seat cushion from the frame upon manually flexing the cushion and engages the cushion with the frame upon unflexing the cushion.
