Abstract
Abstract In a safety belt having a continuous webbing composed of a shoulder side outer webbing piece extended from an upper strengthening member at the side of an automotive body for restricting the breast of an occupant sitting on a seat and a lap side outer webbing piece extended from a lower strengthening member at the side of the body for restricting the waist of the occupant, the continuous webbing has at least one annularly folded portion formed at the continuous webbing and has a plurality of sewing patterns separately sewed adjacent to each other on the folded portion. Thus, the stretching characteristics of shoulder and lap side outer webbing pieces of the continuous webbing are formed to be different to provide buffer and energy absorbing functions of the continuous webbing, thereby further improving the performance of a conventional safety belt.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
174 words
A safety belt secured to a seat for supporting an occupant comprising: an elongated webbed strap having shoulder portion means and waist portion means for retaining the seated occupant in the seat, said waist portion having end straps and expansion means for increasing the tensile strength of said waist portion means, said expansion means including at least one folded member at predetermined positions along said waist portion means and having a pair of strap sections joined along a common crease, each of said strap sections having a substantially corresponding length and being folded along said crease to be in substantially abutting relation, said pair of strap sections having abutting end surfaces opposite said crease, said end surfaces integrally connected to said waist portion means, said expansion means also including woven means for interconnecting said strap sections, said woven means including more than one U-shaped stitch extending longitudinally along said folded member, said expansion means also including suture means connecting said folded strap sections for further increasing the tensile strength provided by said expansion means.
Claim 2
Dependent Claim
174 words
A safety belt secured to a seat for supporting an occupant comprising: an elongated webbed strap having shoulder portion means and waist portion means for retaining the seated occupant in the seat, said waist portion having end straps and expansion means for increasing the tensile strength of said waist portion means, said expansion means including at least one folded member at predetermined positions along said waist portion means and having a pair of strap sections joined along a common crease, each of said strap sections having a substantially corresponding length and being folded along said crease to be in substantially abutting relation, said pair of strap sections having abutting end surfaces opposite said crease, said end surfaces integrally connected to said waist portion means, said expansion means also including woven means for interconnecting said strap sections, said woven means including more than one U-shaped stitch extending longitudinally along said folded member, said expansion means also including suture means connecting said folded strap sections for further increasing the tensile strength provided by said expansion means.
Claim 3
Dependent Claim
35 words
The safety belt as defined in claim 1, wherein said more than one U-shaped stitch is double-stitched, the double stitched interconnected upper ends so that each of said U-shaped stitches has a continuous U-shaped pattern.
Claim 4
Dependent Claim
42 words
The safety belt as defined in claim 1, wherein said folded strap sections have substantially flush side surfaces and wherein said suture means includes at least two sutures extending through said folded strap sections proximate at least one of said side surfaces.
Claim 5
Dependent Claim
38 words
The safety belt as defined in claim 1, wherein said expansion means includes two folded members, one of said folded members providing said waist portion means with greater tensile strength than the remaining one of said folded members.
Claim 6
Dependent Claim
36 words
The safety belt as defined in claim 1, wherein said folded strap sections are folded along said waist portion means and said woven means interconnects said pair of folded strap sections and said waist portion means.
Claim 7
Dependent Claim
19 words
The safety belt as defined in claim 1, wherein said end surfaces of said folded sections are threadably interconnected.
Claim 8
Dependent Claim
169 words
A safety belt secured to a seat for supporting an occupant comprising: an elongated web strap having a waist portion means for retaining the seated occupant in the seat, said waist portion having expansion means for increasing the tensile strength of said waist portion means, the expansion means including at least one folded member at predetermined positions along said waist portion and having a pair of strap sections joined along a common crease, each of said strap sections having a substantially corresponding length and being folded along said crease to be in substantially abutting relation, said pair of strap sections having abutting surfaces opposite said crease, each of said end surfaces being integrally connected to said waist portion, said expansion means also including woven means for interconnecting said strap sections, said woven means including more than one individual U-shaped stitch extending longitudinally along said strap section, said expansion means also including suture means connecting said folded strap sections for further increasing the tensile strength provided by said expansion means.
Claim 9
Dependent Claim
