In a seat having a frame for supporting a seat cushion and a spaced apart, back cushioning arrangement, and an enclosure connected to the frame adapted to store a self-contained breathing apparatus therein, the improvement wherein:
- the frame includes a pair of spaced apart, upright channels, each being C-shaped in cross section and having a pair of inner and outer side walls connected by a rear wall so that each channel is open at a forward end thereof facing the back cushioning arrangement, the back cushioning arrangement having upper hook structure removably engageable with bars extending transversely across the side walls of the channels, and lower hook structure removably engageable with braces extending downwardly and forwardly from the channels, each of the channels having a top end with a cage mounted thereon, one of the cages having a rotating bezel with a guide slot in communication with one of the open, upright channels;
- and
- a seat belt structure is connected to the frame and integrated into the seat and has an internal belt run protectively enclosed inside one of the open, upright channels, and an external belt run connected to the internal belt run and extending forwardly to exit the guide slot for travel across the back cushioning arrangement.
An emergency conveyance seat comprising:
- a frame for supporting a seat cushion and a back cushioning arrangement having a clip-on structure, the frame including a pair of spaced apart, upright channels having open ends facing towards the back cushioning arrangement and top ends with cages mounted thereon, either of the cages having a rotating bezel with a guide slot, the channels being connected by an enclosure adapted to receive a self-contained breathing apparatus, the channels providing a fastener-free attachment structure for removably mounting the clip-on structure of the back cushioning arrangement thereon, one of the upright, open channels providing a protective housing for an internal belt run of an elongated seat belt webbing extending from a refractor positioned adjacent a lower end of the one channel up to the guide slot on the rotating bezel, the seat belt webbing including an external belt run connected to the internal belt run and extending forwardly to exit the guide slot for travel across the back cushioning arrangement, the external belt run having one end fixed to a lower end on one side of the frame and a second end removably joined to a lower end on an opposite side of the frame.
In a seat having a frame for supporting a seat cushion and a spaced apart, back cushioning arrangement, and an enclosure connected to the frame adapted to store a self-contained breathing apparatus therein, the improvement comprising:
- a seat belt structure integrated into the seat and having an internal belt run protectively enclosed inside the frame and an external belt run extending along the back cushioning arrangement,
- wherein the frame includes a pair of spaced apart channels, each being C-shaped in cross section and having a pair of inner and outer side walls connected by a rear wall so that each channel is open at a forward end thereof,
- wherein each of the channels has a bar extending transversely across the side walls and the bar provides a mounting structure for upper hook structure on the back cushioning arrangement, and
