Claim 3
Dependent Claim
103 words
A safety belt buckle as specified in claim 1 wherein said frame includes cage means having an exterior opening, said pushbutton means being slidably mounted in said cage means for slidable linear movement thereof in a direction substantially normal to the linear movement of said latch member, said cage means including a portion positioned for abutment with said second cam face of said cam pad on depression of said push button, abutment of said second cam face with said portion causing said cam pad to move in a direction to urge said first cam face toward said cam surface of said latch member.
Claim 4
Dependent Claim
37 words
A safety belt buckle as specified in claim 1 wherein said retainer arm means of said latch member comprises an elongated arm centrally disposed on said latch member and in substantial alignment with said catch dog member.
Claim 5
Dependent Claim
45 words
A safety belt buckle as specified in claim 1 wherein said retainer arm means of said latch member comprises a pair of spaced-apart outer arm members positioned to overlie the outermost edges of said tongue connector plate at opposite sides of said catch dog member.
Claim 6
Dependent Claim
61 words
A safety belt buckle as specified in claim 4 wherein said latch member includes a centrally disposed arm having an outer end adjacent said catch dog member, said outer end thereof comprising an angled cam face for urging said tongue connector plate into operable engagement with said catch dog member on abutment of said tongue connector plate with said cam face.
Claim 7
Dependent Claim
109 words
A safety belt seat buckle as speCified in claim 1 wherein said tongue connector plate includes a substantially flat platelike body portion having an aperture at one end thereof for receiving belt webbing attached thereto and a tongue portion insertable in said second buckle section, said tongue portion including an aperture for receiving said catch dog means therewithin in releasable operable engagement therewith, and a pair of spaced-apart outer wing portions having a cutaway portion therebetween, said outer wing portions being position for engagement with said frame to provide a pivot axis for lifting of said tongue connector plate in disengagement of the same from said catch dog member.
Claim 8
Dependent Claim
97 words
A safety belt buckle as specified in claim 1 wherein said frame includes a base casing and a cover casing, said base casing including walls defining a trackway, said latch member being slidably mounted in said trackway for slidable linear movement thereof in releasable retention of said tongue plate connector in operable engagement with said catch dog member, and said cover casing includes cage means for defining a pushbutton guide, said pushbutton being slidably mounted within said cage means for slidable linear movement thereof in a direction substantially normal to the linear movement of said latch member.
Claim 9
Dependent Claim
199 words
A safety belt buckle as specified in claim 7 wherein said cage means has a side thereof adjacent said catch dog member, a lower wall portion extendant from said side thereof adjacent said catch dog member, said cam surface of said latch member is angled divergently upwardly and away from said catch dog member, said cam pad slidably engages said push button and has a pair of cam faces, one of said cam faces being positioned for abutment and cooperation with said cam surface of said latch member to urge said latch member away from said catch dog member on depression of said pushbutton and the other of said cam faces abutting the outermost edge of said lower wall portion of said cage means in operable engagement therewith to slidably urge said cam pad away from said catch dog member on depression of said pushbutton, interaction of said cam faces of said cam pad with said outermost end of said lower wall portion of said cage means and said cam surface of said latch member comprising means for movement of said latch member away from said catch dog member a greater distance than said pushbutton travels on depression thereof.
