Lightweight passenger seats that are especially adapted for use in aircraft cabins. The seats will include a seat back and a seat bottom having a basin which defines a recessed central interior space, a plurality of straps having opposed ends connected to respective upper edge regions of the basin so as to be positioned under tension over the recessed central interior space; and a cover cushion covering the straps and connected to the basin. The seat back may be connected at opposed sides thereof to upright support members adjacent a lumbar region thereof so as to establish an upper region of the seat back above the lumbar region which is capable of being resiliently flexed between upright and rearwardly inclined positions.

A seat pan diaphragm assembly and a seat assembly including the same, the seat pan diaphragm assembly including a diaphragm subassembly including a flexible fabric panel having a top, bottom, front, back, and opposing lateral sides, a cargo net subassembly for limiting deflection of the flexible fabric panel under load, the cargo net subassembly including a grid of belts and attachment straps having a clip attachable to a seat frame element, and stiffeners received in slotted sleeves of the diaphragm subassembly and engaging the cargo net subassembly for securing the cargo net subassembly to the diaphragm subassembly.

A vehicle seat in which a swiveling motion of a sub-frame is restricted only to a desirable direction is provided. A sub-frame is suspended from a seatback frame. A first elastic member connects a right upper end of the sub-frame to the seat back frame, and a second elastic member a left upper end of the sub-frame to the seat back frame. A universal joint mechanism connects a lower lateral portion of the sub-frame to a lateral member of the seat back frame.

A vehicle seat assembly has a seat bottom frame, a seat suspension structure, a strap structure and a cushion material. The seat suspension structure is fixed to the seat bottom frame and extends through a seat cushion receiving area of the seat bottom frame. The strap structure is attached to one of a front frame portion of the seat bottom frame and a front end of the seat suspension structure, and is attached to one of a rear frame portion and a rear end of the seat suspension structure. The strap structure extends through the seat cushion receiving area and is slack with a passenger seated on the cushion material. Downward movement of the seat cushion in response to a rapid change in momentum causes the strap structure to become taught restricting further downward movement of the passenger.
