Abstract: A molded strap fastener of a generally rectangular shape includes a first cross bar for retaining therearound a looped end portion of a strap, a retainer portion disposed laterally adjacent to the cross bar and frictionally engageable with the strap end portion, and a second cross bar fixedly connected to the other strap end. The first cross bar includes a pair of diametrically opposite sharp corners and the retainer portion has a sharp corner, these sharp corners serving as stops to retain the strap in position against accidental displacement even under heavy tensioning forces. To provide a greater resistance to strap loosening, the first and second cross bars lie in different levels so that a rotational force is created upon the fastener when the latter is in actual use, said force growing greater the larger the tension and thus urging the retainer portion to firmly grip the strap end at its sharp corner.

Abstract: A buckle of the type used to connect belts used for tying down cargo in vehicles. The buckle is formed of flat plate stock and has a structure adapted to withstand high compressive forces such as are applied to it when it is run over by loaded vehicles. The buckle operates on an overcenter principle, so that once it is locked further tension on the belts tends to keep the buckle locked. In using the buckle, initially the free end of one belt is threaded through the buckle and pulled to take up slack. The free end is jammed between the standing end of the belt and a portion of the buckle, preventing slippage. Next, the handle of the buckle is rotated approximately 180 degrees, which causes the standing part of the belt to be wound around the buckle, thereby placing the belt in tension. Towards the end of its throw, the handle of the buckle passes to an overcenter position, in which further tension in the belt locks the buckle more securely.

Abstract: The invention relates to plate type buckles for safety belts of the kind formed of flat webbing and is particularly concerned with such a buckle wherein engagement between the two parts can only occur when the webbing is not twisted in a way which would lead to slipping occurring when a load is applied to the belt.
