Abstract: A windblast leg protector assembly for use by an occupant of an open-type ejection seat of an aircraft. The assembly includes, for each leg of the seat occupant, a modification to the occupant's conventional anti-acceleration suit by way of a piece of nylon fabric (with concave configurated load spreading cuts, and with a ring captured thereon) attached to the thigh portion, and a similar piece of nylon fabric with a ring captured thereon attached to the calf portion, of each full length leg member of the anti-acceleration suit. Restraining/retracting straps which are connected to, and which remain with the ejection seat, are also constituent components of the windblast leg protector assembly. Snap hooks, which are captured on the slack restraining/retracting straps, are releasably connected by the occupant, after sitting down in the ejection seat, to the captured rings on the thigh and the calf portions of the anti-acceleration suit being worn.

Abstract: An improved arm restraint system for moving the arms of an ejection seat occupant to restrained positions along the sides of the occupant's torso upon initiation of emergency escape ejection of the seat and occupant from an aircraft includes a multistrap and guide ring arrangement wherein the elbow of the aircrewman is drawn tightly against the torso side through a direct interconnection therebetween and concurrently his hands/wrists are drawn to the ejection control of the seat.

Abstract: An aircraft ejection seat position and restraint system for protecting an rcrewman against back injuries during emergency escape. The ejection sequence is initiated by the aircrewman pulling a lower ejection handle or a face curtain handle with both hands to release or shatter the cockpit canopy. A torso harness suit is concommittantly tightened with inflation of a vest worn between the aircrewman and the suit, and catapult rockets are fired to propel the seat out of the cockpit. The harness suit draws the aircrewman's upper torso against the back of the seat while the inflated vest pushes his hips back and down into the seat pan for optimally positioning his spine before ejection thereby negating the effects of an aircrewman purposely or inadvertently flying with a loose harness. After ejection, the seat is separated from the aircrewman but the vest remains inflated inside the harness providing cushioning against the opening shock force of the parachute which is attached to the harness suit.

Abstract: A windblast head protector for use in conjunction with an ejection seat of a high performance aircraft in order to protect the head of a crew member during ejection from the aircraft. The protector includes a deployable U-shaped tubular frame which supports a canopy that extends over the top of a crew member's helmet. The frame is held in place when fully deployed by two cords which extend from the frame's forward edge to two rings attached to the headrest of the ejection seat. The head protector is normally stowed in the pilot chute compartment on top of the main parachute pack of the ejection seat and moved into the fully deployed position by means of cable passing through the frame and operably connected to a deployment mechanism.

Abstract: An aircraft crewman protective system properly positions the lower legs and eet of the crewman during emergency egress from an aircraft. The system includes a pair of plate members connected to swing outward from the under side of the crewman's console at each leg position and means for deploying the plate members at the time of ejection. Upon deployment, the plate members push the feet of the crewman backward guiding the feet and lower legs within a contact-free envelope during ejection without changing desired spinal position of the crewman.

Abstract: A pilot limb retention system for an aircraft ejection seat comprising two main straps, two secondary straps and two nets coupled to the seat. The system includes a stowage assembly and a deployment system for the straps and nets. The stowage assembly comprises two compartments in the seat back and two compartments in the seat pan. The deployment system comprises four inflatable bladders, two adjacent the knees of the pilot on opposite sides of the seat pan and two adjacent the shoulders of the pilot on opposite sides of the seat back. These bladders are also stowed in the compartments and are releasably connected to the main straps.

Abstract: A G-protective seat is disclosed for disposing an occupant within a vehicle n a supine tucked posture during high acceleration loading substantially along the Z-axis of the vehicle. At the onset of high Z-axis acceleration, a pair of pivotal leg support members are actuated to fold the legs of the occupant upwardly thereby drawing the knees up to the chest of the occupant in an intermediate tucked position. With the occupant in the tucked position, the seat rotates upward about an axis substantially defined by the occupant's eyes into a supine position for the duration of the high acceleration loading.

Abstract: A system for preventing injury to a motorcyclist in the event of a crash employs a rigid framework surrounding the upper body of the cyclist and inflatable air bags which both surround the cyclist with the ballooning air cushion and also serve to draw the cyclist's legs upwardly to prevent injury during the crash. A rigid body shell may be employed to encase the torso of the cyclist, or a space frame formed of a plurality of rigid elements may be utilized to protect the cyclist in the crash. A specialized seat can be employed which serves to eject the cyclist from the cycle when a crash is either imminent or is actually occurring.

Abstract: An ejection seat-mounted system for temporary secure attachment of the li of an aviator or other user to the seat during ejection, preventing limb flail and consequent injury. Initially, two rigid arm restraints are pivotably mounted to the sides of the seat in a nonobstructive raised position, and two rigid leg restraints are mounted at the sides of the seat in a substantially nonobstructive extended position to help keep the aviator's legs in place. After the aviator pulls a D-ring initiating ejection, a first gas generator is fired, causing pivoting of the two seat-mounted arm restraints through 135.degree., and retraction and rotation of the two seat-mounted leg restraints, each of which captures one of the aviator's limbs, draws it to the seat, and holds it in place on or with respect to the seat.

Abstract: A piston return stop device for seat belt tensioning equipment. Connected at one end to a seat belt through a cylinder is a piston having a tapered portion the diameter of which enlarges toward its other end. A cylindrical sliding member is slidably disposed between the cylinder and piston so as to slide together with the piston when the piston is thrust to tension the seat belt. A respective stopper member is slidably disposed within each guide groove radially perforated through the cylindrical sliding member and supported by the tapered portion of the piston.When the piston is thrust through the cylinder at an urgent time until the tension force of the seat belt reaches a predetermined value, the piston is stopped from moving within the cylinder furthermore and only the cylindrical sliding member slides within the cylinder due to its inertia force together with the stopper members. Then the stopper member is pushed up by the tapered portion of the piston to cut into the inner wall of the piston.

Abstract: A seat mounted arm restraint net system for restraining a crewman's arms during an ejection sequence wherein a pair of nets, mounted with one on each side of the seat, are deployable by separate static lines passing through snubber boxes to frangible anchorages on the vehicle floor. Each static line is releasably attached to a separate swinging arm rotatably secured to its seat side such that the swinging arms throw the free net sides laterally outwards and then release the nets to close over the crewman's arms.

Abstract: An arm restraint system for use with an aircraft ejection seat to prevent limb flailing on ejection. Long straps, which are normally loose to allow unimpeded arm and body movement of the seated crewman, are retained high on the side of the shoulder area by a flap with a Velcro fastener and by ring members on the seat buckle and on the seat frame. During the ejection sequence, the Velcro fasteners are pulled apart by the action of the straps which move downward and pin the crewman's arms against his side and lower abdomen thereby preventing flail upon entry of the crewman into the airstream.

Abstract: A man-carrying vehicle modified with a device for alleviating accelerative forces particularly useful for space travel is provided with a personnel carrier which automatically orients its occupant, with an imaginary Z-axis parallel to the spinal column and through the centers of mass of cross sections of the body and of the head perpendicular to the Z-axis such that the Z-axis is in a position normal to the resultant of the forces of acceleration, and which rotates the occupant about the Z-axis to alleviate or counteract the effects of the forces of acceleration in the X and Y directions normal to the Z-axis.

Abstract: A roller harness arrangement for airplane pilot seats arranged side by side. The roller mechanism for each pilot seat is, respectively coupled to a winding mechanism which is controllable by the pilot in the other pilot seat.

Abstract: Triangular net-like arm restraining members, one for each side of an aircraft ejection seat, extend during the first phase of ejection so that each has an upper corner near the top of the back portion of the seat, a front corner near the front of the horizontal seat portion, and a lower corner near the junction of the back and seat portions. The upper corner of each restraining member is anchored near the top of the back portion, at its side thereof. The restraining members are normally furled and extend laterally outwardly from the back portion to the cabin wall, thence forwardly along the cabin wall, to be spaced, embracing relation to the seat occupant's shoulders. Upon ejection, one tension element for each restraining member draws its front corner forwardly, downwardly and laterally inwardly; another draws its lower corner downwardly.

Abstract: An articulated high "G" force aircraft seat which is movable between a conventional upright position and a reclined position. As described, the head and eyes remain in a relatively stationary position without affecting instrument monitoring or external vision. The aircraft controls remain within easy reach, yet the pilot is able to sustain high acceleration maneuvers in excess of eight "G's".

Abstract: An arm restraint system comprises for each arm of the occupants a sleeve to which a tape is connected at two spaced points. A ring, slidable on this tape, is connected, through a disengageable barrel connector, to a second tape which runs through a snubber block and is connected to the vehicle via a shear pin. Ejection of the occupant pulls the second tape through the snubber block and through the barrel connector, the first tape across the occupant thus drawing the arm through the sleeve down to the occupant's side.
