  • the safety belt or harness for the seat occupant can be anchored tothe seat itself rather than to the main body structure of the vehicle. It is an object of the invention to provide a seat of this kind.
  • the seat frame is designed so that the seatroccupant restraining forces are taken by a structure of cross-form configuration somewhat akin to the human spine and hip formation.
  • the structure comprises a hip frame with lateral wing portions situated at the region where the base and the back of theseat meet and incorporating the main anchorage points for the seat. And from this hip frame there extend upward andforward, respectively, a central back spine and a substantially horizontal basespine. On this structure are fitted seat and back cushions for the occupant and preferably also an adjustablehead rest.
  • That seat loads normally high in the seat pan and low in the seat back, can be suddenly reversed when subjected to crash conditions.
  • the conventional harness lap and diagonal" restraint system by virtue of its three point construction, provides anchorage of the imposed loads in a plane behind the wearer and never on the seat pan.
  • the invention provides a seat construction compatible with these considerations.
  • the preferred material of construction of the seat frame is pressed steel, but for aircrew seats filament-reinforced synthetic resin materials, e.g. glass materials, are preferable.
  • FIG. 1 is a front elevation of the seat frame
  • FIG. 2 is a side elevation
  • FIG. 3 is a rear elevation
  • FIG. 4 is a plan
  • FIG. 5 is a view in section on the line 5-5 of FIG. 2,
  • FIG. 6 is a view in section on the line 6--6 of FIG. 5, and
  • FIG. 7 shows an arrangement for connecting a harness strap to the seat.
  • the frame of the seat shown in the drawings is pressed in sheet steel and has as its main structuralportions a hip frame 1 1 with lateral wings 12, a back spine 13 upstanding centrally from the hip frame, and a horizontalseat spine 14 extending forward centrally from the hip frame. Integral with the seat spine 14 is a seat tray or pan 15 to receive the seat cushions 16, which is a separate item for ease of manufacture and fitting.
  • the pan I5 is pressedwith lateral ribs 17, extending from the spine 14, to stiffen it.
  • the hip frame 11 is a strong box-type structure made up by mating two half-pressings 11A, 118, the one joined to the back spine 13 and the other to the seatspine 14,
  • the hip frame is comparatively deep, more particularly at or carbon fiber its central region 19, in the plane of juncture 18 of the two half-pressings, which plane contains the horizontal axis of the hip frame (the hip frame axis that lies at right angles to the fore-and-aft vertical center plane of the seat) and slopes steeply down in the rearward direction.
  • the two spines 13, 14 deepen progressively in section as they approach the hip frame, encountering it in two planes 21, 22 parallel to the plane 18, the terminal depth of each spine in the plane 21 or 22, as the case may be, being substantially the same as the depth in that plane of the central region of the hip frame.
  • the central region 19 of the hip frame 11 extends somewhat below the wings 12, as at 23, and provision is made here for the main attachment of the seat to supporting vehicle structure, the horizontal axis 25 of the attachment points 24 lying in the plane 18.
  • a compression strut is provided under the seat spine 14 as indicated at 26.
  • the back spine 13 widens at its top region 27 to give adequate support to the seat occupants shoulders. It carries a fixed shoulder cushion 28, a separate adjustable lumber cushion 29 and an adjustable head rest 30, this arrangement giving excellent back support and ventilation.
  • the seat can be equipped with safety belt or harness gear of the retracting type, either lap-and-diagonal or a full harness. Shoulder webbing locations, in relation to the seat back, are shown at 31, this webbing running down within the back spine 13 at the rear to a retraction reel 32 secured about half-way up the back spine.
  • FIG. 7 shows how this can be accomplished, the harness strap 33 being looped through an anchorage plate 34 which is held in place by an anchorage bolt 35 secured in an end-piece 36 fitted on to the end of the hip frame 11.
  • the lower end attachment for the diagonal strap is on the outside of the seat, that is to say the diagonal strap extends upward and inward away from the side of the vehicle, instead of out toward the side in the conventional manner.
  • seat adjustment means are not illustrated, it is readily possible for such a seat construction to be adapted to afford any of the usual vehicle seat movements, e.g. fore-andaft travel, rake. adjustment, recline and lift-up; and it can also be adapted for height adjustment and swivel if used as an aircrew seat.
  • a vehicle seat frame comprising a hip frame having lateral wings, a back spine upstanding centrally from said hip frame, a horizontal seat spine extending forward centrally from said hip frame, a seat tray integral with said seat spine, said seat tray having stiffening ribs, said back spine and said seat spine being fixedly joined to said hip frame, said back spine and said seat spine having progressively increasing cross sectional areas in the region of their juncture with said hip frame, the terminal width of the cross section area of each of said back and seat spines being substantially equal to the width of said hip frame.
