  • Patent number: 4576414
    Abstract: Many seat belt configurations have incorporated a belt retraction device into the design of the seat belt apparatus. When the retraction device includes a recoil spool that is housed within the buckle member the function of the buckle member becomes compounded. In order to release the seat belt buckle the operator is often required to move the release handle in a manner that necessitates the use of both his hands. The seat belt apparatus of the present invention provides a buckle member that is moved toward a tongue member to achieve a latching engagement between the two. A latch release member is provided within the buckle housing and is movable in a direction away from the tongue member to release the connection therebetween. This direction of movement is the same as the direction of separation between the buckle member and the tongue. Both operations may be accomplished in one motion and require the use of only one hand.

  • Patent number: 4449357
    Abstract: The invention described herein concerns a forging process for the manufacture of track chain links, especially for worksite machines and vehicles; this process produces links that conform to the tolerances required by the dimensions and the surface quality of opposed attachment mounting and link contact surfaces and nut seats of finished links without it being necessary to machine these surfaces or nut seats. This process includes heating a metal billet in an electric furnace, the billet having a mass that is approximately equal to that of a finished link, preforming the billet, then flat stamping the heated billet. A combined shaping and levelling step carried out on the stamped piece forms parallel opposed sides and nut seats in predetermined spaced relationship to each other. The resulting link is controllably sized and then subjected to a heat treatment.
