  • Patent number: 5712011
    Abstract: A tug-resistant unit in which the first and second relatively inextensible members overlap one another. A shear-thickening composition having dilatant flow characteristics is disposed between the first and the second inextensible members. The composition provides a variable resistance to linear movement of the second inextensible member relative to the first inextensible member as a function of the shear forces exerted upon the dilatant fluid. The inextensible members may be enclosed within an extensible enclosure to form an elastic strap. Alternatively, one inextensible member may form a portion of the enclosure while the second inextensible member is disposed within the strap so as to overlap the first inextensible portion of the enclosure. The strap provides low resistance to slowly-varying tensile forces and high resistance to rapidly-changing tensile forces, thereby moderating the velocity of relative motion between the ends.

  • Patent number: 4316307
    Abstract: An end connector for a wire rope suspension system has a shifting mechanism for minimizing wear and has body members which inhibit undesired binding of loaded wire ropes internal to the connector. Two substantially identical body members are adapted to be preassembled in stages on the wire rope and then coupled together in place in the suspension system. Within each one of the body members is a sheave mounted to a journal bearing. The sheave bears the load of the wire rope on the body and can rotate under load to minimize frictional resistance to desirable displacement of the body piece relative to the rope ends. The end connector with displaceable load-bearing body members minimizes wear and increases the life of wire rope suspension systems.

  • Patent number: 4310177
    Abstract: A load locking junction device for coupling a continuous-loop belt having ends mounted on the door with an anchor belt retractably mounted inboard the seat includes a frame having an aperture defining spaced apart first and second load bearing walls. The continuous-loop belt is slidable over the first wall to define a lap belt portion and a shoulder belt portion. The anchor belt extends through the aperture and has a pin engaged in the end thereof to enlarge the end for simultaneous engagement against the second wall and the continuous-loop belt so that the belts are coupled together and maintained in engagement with the load bearing walls. A spring acts on the pin to space the anchor belt from the continuous-loop belt to permit movement of the continuous-loop belt through the frame.
