Abstract
A buckle and tongue combination comprising a ferrule, channeled for acceptance of a bifurcated tongue. A latch member straddling the ferrule, and pivoted thereto, is biased for latching engagement with the tongue. The tongue may be disengaged by pressure in opposition to the bias, applied to a lever which constitutes an extension of the latching member.
Claims24
A buckle and tongue combination comprising:
- a. an elongated, substantially cylindrical member having guiding means at one end for guiding a tongue and means at the other end for the attachment of a passenger restraint;
- b. a tongue having legs separated by a distance greater than the width of the elongated member, said legs having engaging means for sliding engagement with the guiding means of the elongated member;
- c. a latch member pivotally mounted on the elongated member and having at least one latching tooth to engage the tongue;
- d. biasing means mounted on the elongated member for urging the latching tooth into engagement with the tongue;
- and
- e. a release lever attached to the latch member, whereby pressure on said lever in opposition to the biasing means disengages the latching tooth from the tongue, allowing its withdrawl from the buckle.

A buckle and tongue combination comprising:
- a. a ferrule having a passenger restraint attached at its rear end, and having a channel at its front end, parallel to the ferrule on each of the two opposite sides, extending at least partially toward the rear end;
- b. a tongue having a bifurcation for engaging the ferrule, the thickness of the bifurcated portion of the tongue being slightly less than the width of the channels of the ferrule, the bifurcation having legs on their inner edges parallel and separated by a distance greater than the width of the ferrule, said legs having at their ends, symmetrical projections extending inwardly, separated by a distance slightly greater than the distance between the channels of the ferrule measured through the ferrule, whereby these projections can be slideably inserted into the channels leaving openings exposed on each side of the ferrule, said openings extending to the inner edges of the legs of the bifurcation;
- c. an elongated latch member having a forward section with a U shaped cross section straddling the ferrule down to about the top edge of the channels, and latching teeth extending from the sides of the forepart of this forward section downward to about the bottom edge of the channel to engage said exposed openings of the inserted tongue, the rear part of the forward section of the latch member having legs extending below the longitudinal axis of the ferrule and pivoted thereon for limited rotation sufficient to allow the latching teeth to be moved in and out of latching engagement with the tongue, a rear section of the latch member having a release lever for rocking the pivoted latch member out of a latching engagement with the tongue;
- and
- d. biasing means maintaining the latching member in its latched position.

A buckle comprising:
- an elongated, substantially cylindrical ferrule, channeled on opposite sides at one end for engaging a bifurcated tongue, and a latch member with at least one latching tooth, said latch member straddling the ferrule and pivoted thereto for rotation in and out of latching engagement with corresponding openings in the tongue, said latch member being biased to its latched position and having a lever extended therefrom for the manual release of the tongue.
A buckle and tongue combination comprising:
- a. a ferrule having longitudinal channels at one end for guiding a tongue and means at the other end for the attachment of a passenger restraint;
- b. a tongue having two legs separated by a distance greater than the width of the ferrule, said legs having at their ends, inwardly directed projections separated by a distance less than the width of the ferrule, for sliding engagement with the longitudinal channels of the ferrule;
- c. a latch member pivotally mounted on the ferrule, having at least one latching tooth to engage the tongue;
- d. biasing means mounted on the ferrule for urging the latching tooth into engagement with the tongue;
- and
- e. a release lever attached to the latch member, whereby pressure on said lever in opposition to the biasing means disengages the latching tooth from the tongue, allowing its withdrawal from the buckle.
