A seat cushion 10 for an aircraft ejection seat 12 includes a plurality of rear edge securing straps 70,72 attached to the lower surface 58 of the seat cushion. The rear edge securing straps each have a free end 78,80 that includes a pull-the-dot fastener 82,84 that engages a corresponding pull-the-dot fastener 42,44 at the rear edge of the seat pan 14. A plurality of front edge securing straps 20,22 are fixed, at one end, to the seat pan near its rear edge and have free ends that pass through bight portions 66,68 of front edge straps 62,64 to be secured by fastenings 100 at the front of the pan. The length of the rear edge securing straps is selected so that when the seat cushion is installed, the rear edge securing straps are pulled substantially flat so that the seat cushion is firmly held in place. When the front edge of the seat cushion is released, the seat cushion can be lifted up enough to allow the cushion to be released without pulling at the bottom of the seat cushion. |
