1,049,411. Safety belt buckles. R. EBERHART. Feb. 13, 1964 [March 28, 1963], No. 6091/64. Heading E2A. A buckle for a safety belt with two sections, comprises male and female portions 22, 20, the female portion including a body 36 with a back and two sides, a lever 30 in one end of the body, spring means 42 urging the lever forwardly and means e.g. a shaft 100 for receiving one end of the belt section 26, the lever and male portion having releasable interlocking means resilient means 44 contacting said male portion and urging said male portion forwardly for disengaging said lever and male portion and means on said male portion for receiving one end of the other belt section 24. The lever 30 has an upwardly extending boss 52 providing a rigid shoulder 54 to hold the male portion in locked position by engaging a slot 62 therein. When the portion 22 is fully inserted in the portion 20 it engages finger 44 placing the spring 42 under tension to hold the portion 22 firmly and thus prevent rattling. The lever 30 can be unlatched by a pivoted lever 80 which also forms part of the front cover and has an inwardly extending arm 88 which engages the inner edge of lever 30 urging it downwards as the cover lever 80 is raised to release the shoulder 54 so that the tension of the spring 44 ejects the portion 22. The cover lever is held in place in the latched position by lugs 92, 94 on the lever 30 engaging an extended portion 96 of the cover lever 80. The belt section 24 is attached to the male portion by looping it through a slot 28 and securing the free end to the remainder of the belt. The shaft 100 is supported in a frame 102 and under a bar 104 rigidly mounted on the side walls of the body 36. The frame 102 is slidable in the body 36 to clamp the web 26b between the bar 104 and the shaft 100 (Fig. 6) when the belt is under tension. The belt may be tightened by merely pulling the belt around the shaft and loosened by moving the frame 102 to the left and thus releasing the clamping action to allow the belt to be moved. |
