Safety Belts Patents (Class 244/122B)
  • Patent number: 5961073
    Abstract: A seat assembly for commercial aircraft or other vehicles has features that reduce head excursion in high impact events such as crashes or collisions. These include the use of low-elongation seatbelt material and high seatbelt anchor location. Another feature which reduces head excursion is an articulating seatpan. The bottom seat cushion is guided by rollers in tracks to follow a prescribed motion under forward inertial load. As the inertial load is applied, the seatpan travels forward and tilts upward. This reduces forward pelvic rotation which, in turn, reduces head excursion. Other features which limit pelvic rotation are the use of dynamically stiff foam for the seat cushion, and a relatively steep initial cushion angle/cushion contour.

    Abstract: An apparatus for storing infant's safety seat within a movable passenger carrying transporter such as an aircraft or bus in the transporter's bulkhead section. The seat may be stored in a compartment located within a table or within a formed bulkhead storage compartment. When stored in a table, a hinged connection pivotally mounts the seat to the table. When in the bulkhead compartment a vertical door permits the infant to be placed within the seat in the compartment. In either embodiment an infant accessory storage mesh bag may be used to store infant items such as diapers, toys, or other infant care items.

  • Patent number: 5746395
    Abstract: A helicopter safety system provides an increased likelihood of survivability without injury during "survivable" helicopter crashes. The system provides spinal compression for precompressing an operator's spine in response to a crash signal from a crash sensor. Also included is a strap tensioning device which tensions an inertia reel strap and thus restraining the operator's upper body more effectively in the helicopter seat. Preferably, the strap tensioning device is initiated simultaneously with the spinal compression. Also included are energy absorbers connected to the seat pan, for example, between the seat pan and the seat frame, and airbags connected to the harness. The harness also includes a cross coupling element to provide for a lateral support configuration.

  • Patent number: 5732907
    Abstract: An ejection seat buckle assembly and an arm restraint system incorporating such a buckle assembly wherein the buckle of the assembly includes latch and strike portions each having a respective cable guide ring integrally formed therewith. Arm restraint cables passing through the guide rings deploy safety nets or pull the sleeves or arms of an occupant inward toward the occupant's torso or lap to prevent arm injury during seat ejection from an aircraft. In one embodiment, the guide rings are formed integrally with the latch and strike portions by forming generally oval shaped openings in lap belt adjusters mounted to respective latch and strike engagement portions by latch hinges. In another embodiment, the cable guide rings are D-shaped rings integral with the latch and strike of the ejection seat buckle.

  • Patent number: 5282648
    Abstract: The present invention relates to an inflatable air bag apparatus attached to a harness restraint system in a vehicle which inflates if an impact sensor detects an impact. The apparatus comprises an bladder attached to the harness's shoulder strap. The sides of the bladder wrap around the shoulder strap and are folded on top of the shoulder strap. When an impact is detected, the impact sensor transmits an electrical signal which ignites the gas generator, and inflates the bladder. In a preferred embodiment, the bladder member comprises three chambers, a central chamber and two side chambers. The chambers are formed by two vertical webs that divide the bladder into the central chamber and the side chamber. The webs are fabricated from permeable material, such that the side chambers inflate before the central chamber inflates, thus stabilizing the air bag apparatus.

    Abstract: A seat belt for a pilot seat or flight attendant seat in an aircraft includes a belt tightener with a reversible energy storage member in the form of a helical compression spring and a rod-shaped energy converter coupled to the energy storage member. The energy converter is at least indirectly connected to a belt member of the seat belt. After the belt member has been tightened and the energy converter has been displaced as a result with an at least partial regeneration of the energy storage member, a cutting chisel penetrates the surface of the energy converter and dampens the movement of the belt member. A renewed activation of the energy storage member after the deceleration phase is prevented by the penetration of a clamping edge of a clamping member in the surface of the energy converter.

  • Patent number: 4437628
    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.

There is provided a safety belt for such use as motor vehicles or aircraft, which will normally have only light tension thereon to permit easy movement of the safetied person on the seat of the vehicle or aircraft but which upon sudden change in speed of the vehicle or aircraft will impose a sufficient strong restraint against unwinding thereof as to effect the desired support of the person to whom the safety belt is applied. The device is particularly adapted for fitting into relatively small spaces and is fully integrated for providing its operation without external connections. Particularly, the device embodying the invention is provided with a belt-carrying winch in which a spring maintains a light windup tension thereon. Acceleration sensitive means initially locks the winch to prevent unreeling of the belt and immediately thereafter releases said lock, winds the belt as needed to remove any slack therefrom and applies a brake against further unreeling of the belt.
