Seat Separation Patents (Class 244/122AH)
  • Patent number: 5573205
    Abstract: A first rack is maintained in spatial relationship from a pinion so that the rack may be moved vertically with a pilot's seat, thereby accommodating height adjustments. An actuating handle is connected, via a cable, to a linkage which displaces the rack toward engagement with a pinion gear. A second rack is normally maintained in engagement with the same pinion gear and is driven by it. When the pinion gear is driven by the first rack, the second rack follows and it pulls upon a cable connected at an opposite end to a seat firing head.

  • Patent number: 5558309
    Abstract: A structure comprising a plurality of adjacent seats for a public passenger vehicle, in particular an airliner, the structure being convertible and of variable size along a sliding axis (100), and comprising:a fixed portion (2) comprising at least two transverse underframes (4) that are spaced apart from each other, fixed to the floor of the passenger cabin, and rigidly connected to one another by longitudinal underframe elements (5) having an axis that is generally parallel to the sliding axis;at least one moving portion (3) that is movable relative to the fixed portion between two extreme positions, namely a maximum-size first position and a minimum-size second position, the moving portion (3) including an end transverse seat side member (6) rigidly associated with longitudinal support elements (7), and intermediate transverse seat side members (8) parallel to the end transverse seat side member (6) and associated with the longitudinal support elements (6), and serving to mount seat backs and arms; andlocki

  • Patent number: 5261630
    Abstract: A pilot's ejection seat is propelled in an upward direction after ejection by employing a high gain signal from a radio altimeter on board an aircraft. The vertically downward high gain vector is inverted by adding 180.degree. to its phase component and providing the resultant signal to an inexpensive gyro or assembly of gyros installed in the seat. The gyros are constantly updated with information concerning the upward vertical direction and upon ejection, the gyros maintain this information for a sufficient period of time to control the ejection seat propulsion system in a manner achieving a vertically upward trajectory that will enable the pilot to clear a disabled aircraft and achieve the orientation necessary to deploy a parachute.

  • Patent number: 5067671
    Abstract: Ejection seat rails that guide an ejection seat out of a vehicle, wherein the seat has rollers that travel along the rails. The rails are constructed such that the rollers simultaneously disengage from the rails, reducing the amount of tip-off that would occur if the rollers were to sequentially disengage.

  • Patent number: 4938436
    Abstract: A harness and belt assembly for a crewmember of an aircraft including left and right slings, a first belt assembly having first end second ends, a survival kit strap assembly attachment fitting which slidably engages the belt assembly, and a mechanism for releasably attaching the fitting to a seat of an aircraft. The slings are designed to extend from the chest of the crewmember, over the crewmember's shoulders, to the back of the crewmember. The first end of the belt assembly is attached to one of the slings at the portion designed to be adjacent the crewmember's chest. The second end of the belt assembly is attached to the other of the slings. A survival kit belt can be affixed to the fitting so that the survival kit ejects with the crewmember during an ejection.

  • Patent number: 4667902
    Abstract: A pilot arm retention system for an aircraft ejection seat which includes ertia reels and a parachute is comprised of a pair of nets connected between respective sides of the seat and a pair of deployment straps which are releasably coupled to the inertia reel straps and parachute risers and routed down over the front of the seat through a pair of snubbers to fixed points on the cockpit floor.

  • Patent number: 4225101
    Abstract: A collision avoidance system having a seat parachute deployment system secured to the pilot's seat. The seat parachute deployment system has a flap member secured to the survival kit on the side remote from the pilot. The flap member drops down to prevent entanglement of the seat parachute or suspension lines with the pilot's legs. The seat parachute is stowed in an elongated sleeve on the flap and is drawn from the sleeve during seat separation. The suspension lines are stowed in a conventional manner. A connecting line, connected between the suspension lines and seat attachment lines, is stowed in elongated sleeves on the flap.
