Abstract
Abstract A buckle comprises a buckle body and a cam rotatably mounted at one end of the buckle body. A support plate with an aperture at one end thereof is pivotaly mounted along one side of the buckle body. When the support plate is pivoted to its closed position, the aperture or bearing on the support plate helps support the cam. When the support plate is in the upper position away from the side of the buckle body, seat belt webbing can be inserted between the cam and the buckle body. The cam is so configured that a force pulling on one end of the webbing causes the side of the cam on the side on which the webbing force is applied to move away from the buckle body, and consequently the other side of the cam moves up toward the buckle body, whereby the webbing which is between the cam and the buckle body is gripped by the cam surface and an extension of the buckle body. Another extension of the buckle body is on the other side of the cam and the cam is symmetrical so that a force on either side of the cam by either end of the webbing will function to grip the webbing between the cam and an extension of the buckle body.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
238 words
In a device for connecting webbing to a buckle including a buckle body with limiting means mounted thereto, and cam means mounted on said buckle body, said cam extending longitudinally for engaging the width of the webbing between itself and the limiting means, the improvement comprising the provision of: first supporting means on said buckle body for supporting one longitudinal end of said cam means for pivoting movement about its longitudinal axis and permitting movement of said longitudinal axis through an arcuate path; second supporting means associated with said buckle body and movable between a first position for supporting said other longitudinal end of said cam means for pivoting movement of said cam means about said longitudinal axis and preventing arcuate movement of said longitudinal axis of said cam and to a second position releasing said end of said cam and permitting the axis to move in said arcuate path whereby when said second supporting means is in its second position, said webbing being insertable between said cam and said limiting means when said cam is moved in an arcuate path, and when said second supporting means is in its first position, said webbing is prevented from being removed from between said cam and limiting means whereby pulling on an end of the webbing causes said webbing to pivot said cam means about said longitudinal axis to grip the webbing between said limiting means and said cam means.
Claim 2
Dependent Claim
238 words
In a device for connecting webbing to a buckle including a buckle body with limiting means mounted thereto, and cam means mounted on said buckle body, said cam extending longitudinally for engaging the width of the webbing between itself and the limiting means, the improvement comprising the provision of: first supporting means on said buckle body for supporting one longitudinal end of said cam means for pivoting movement about its longitudinal axis and permitting movement of said longitudinal axis through an arcuate path; second supporting means associated with said buckle body and movable between a first position for supporting said other longitudinal end of said cam means for pivoting movement of said cam means about said longitudinal axis and preventing arcuate movement of said longitudinal axis of said cam and to a second position releasing said end of said cam and permitting the axis to move in said arcuate path whereby when said second supporting means is in its second position, said webbing being insertable between said cam and said limiting means when said cam is moved in an arcuate path, and when said second supporting means is in its first position, said webbing is prevented from being removed from between said cam and limiting means whereby pulling on an end of the webbing causes said webbing to pivot said cam means about said longitudinal axis to grip the webbing between said limiting means and said cam means.
Claim 3
Dependent Claim
28 words
The improvement of claim 1, further including the provision of said second support means being pivotally connected to said buckle body between its first position and second position.
Claim 4
Dependent Claim
108 words
In the device of claim 1 wherein said cam includes a central portion and two transverse portions on opposite sides of said central portion from each other, said limiting means further including a pair of gripping surfaces for gripping said webbing between said cam and either of said gripping surfaces, the improvement further including the provision of cam extension surfaces on each side of said cam extending transversely past both gripping surfaces to increase the moment of force from said webbing on one side of said cam to increase the force from said cam on the webbing between the other side of said cam and the gripping surface.
Claim 5
Dependent Claim
158 words
The improvement of claim 1 further including the provision of having said cam including a cylindrical surface about the longitudinal axis of rotation of said cam, said cylindrical surface extending a substantial angle more than half way about said axis of rotation, two first planar surfaces intersecting said cylindrical surface, and wherein the plane of said first planar surfaces includes said longitudinal axis of rotation of said cam, said first planar surfaces acting as clamping means to clamp the webbing between one of said first planar surfaces and said limiting means on said buckle body upon pivoting of said cam, and two second planar surfacEs intersecting said first planar surfaces to extend the moment arm of force applied to the cam on one side of the longitudinal axis of rotation whereby a large force is transmitted to said clamping means for clamping said webbing at said limiting means on the other side of said longitudinal axis of rotation.
