  • Patent number: 4465250
    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.

  • Patent number: 4370000
    Abstract: A seat for motor vehicles includes a pair of adjustable lateral edges on at least one of the seat cushions and backrest cushions to impart lateral restraint suitable to the occupant, the lateral edges being pivotally mounted on stationary brackets and mechanically connected to each other by a connecting link. One of the lateral edges includes a pawl engageable with one of the teeth provided on one stationary bracket and releasable therefrom upon rotation of one lateral edge in one direction. The rotation of the other lateral edge in the opposite direction causes the selective engagement of the pawl as well as the opposite rotation of one lateral edge, thereby performing the lateral restraint of the seat without any lever or knob projecting out of the seat.

  • Patent number: 4247064
    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.

  • Patent number: 4234228
    Abstract: A seating system which can be adapted to the particular body size and required spatial orientation of a disabled person to hold him securely and in an orthopedically correct required position, and which can be fitted to any patient in a manner that minimizes the amount of custom craft work and cost. The seat includes a frame having three shells, including a lower seat back shell that can pivot and shift relative to the seat bottom shell and the upper back shell. A cushion system which includes a group of individual cushions can be rapidly installed on the shells to closely fit the individual. The shells can be independently adjusted to control the general contour of the thighs, back, hips and shoulders. Different cushions can be chosen to closely control the patient's orientation and to snugly but comfortably fit him into the adjusted frame.

  • Patent number: 4215835
    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.
