Abstract
Abstract Belting for safety belts, particularly for vehicles, having at least one side margin comprising an externally rounded protective profiled element, this element preferably being in the form of a tube. The belting, including said elements, may be woven in one piece. The warp threads in the woven tubular element preferably have a higher coefficient of elongation at break than those of the belt portion, so that under load they will not break before the warp threads of the belt portion. In order to achieve this, the warp threads of the woven tubular element may be shrunk before weaving.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
173 words
Woven belting for safety belts including: a longitudinally extending, single layer woven belt portion of textile material having warp and weft threads and having opposite longitudinal side margins, and at least one protective profiled element extending along one of said side margins, said protective profiled element being in the form of a woven tube of textile material having warp and weft threads and a weave in which -- alternates with --, said protective element being integral with said belt portion with said woven tube and belt portion having common weft threads, wherein the coefficients of elongation at break of the warp threads of the said element are higher by a percentage a than the coefficients of elongation at break of the warp threads of the belt portion and the percentage a is at least substantially equal to a percentage b by which in a predetermined length of belting the actual lengths of the warp threads of the belt portion are greater than the actual lengths of the warp threads of the said element.
Claim 2
Dependent Claim
173 words
Woven belting for safety belts including: a longitudinally extending, single layer woven belt portion of textile material having warp and weft threads and having opposite longitudinal side margins, and at least one protective profiled element extending along one of said side margins, said protective profiled element being in the form of a woven tube of textile material having warp and weft threads and a weave in which -- alternates with --, said protective element being integral with said belt portion with said woven tube and belt portion having common weft threads, wherein the coefficients of elongation at break of the warp threads of the said element are higher by a percentage a than the coefficients of elongation at break of the warp threads of the belt portion and the percentage a is at least substantially equal to a percentage b by which in a predetermined length of belting the actual lengths of the warp threads of the belt portion are greater than the actual lengths of the warp threads of the said element.
Claim 3
Dependent Claim
34 words
Belting according to claim 1, wherein the protective profiled element has a cross-section which is rounded at least over that part of its periphery which does not abut the belt portion of the belting.
Claim 4
Dependent Claim
43 words
Belting according to claim 1, wherein the protective profiled element has a thickness which is no greater than that of the belt portion of the belting and wherein the protective profiled element does not project beyond either major surface of the belt portion.
Claim 5
Dependent Claim
22 words
Belting according to claim 1, wherein the protective profiled element has a lower weft density than that of the woven belt portion.
Claim 6
Dependent Claim
36 words
Belting according to claim 1, wherein the protective profiled element has half the weft density of the woven belt portion, the belt portion of the belting having a -- weave with single weft insertion per shedding.
Claim 7
Dependent Claim
19 words
Belting according to claim 1, wherein the belt portion and the protective profiled element have the same weft density.
Claim 8
Dependent Claim
22 words
Belting according to claim 1, wherein the warp threads of the protective profiled element are finer than those of the belt portion.
Claim 9
Dependent Claim
85 words
Belting according to claim 1, wherein the belt portion and said element are woven from warp threads whose coefficients of elongation at break originally differed by a percentage different from the percentage b, but which, before weaving, have been treated by so shrinking the warp threads of the said element that the resulting coefficients of elongation at break of the warp threads of the said element are greater than those of the warp threads of the belt portion by at least substantially the percentage b.
Claim 10
Dependent Claim
85 words
Belting according to claim 1, wherein the belt portion and said element are woven from warp threads whose coefficients of elongation at break originally differed by a percentage different from the percentage b, but which, before weaving, have been treated by so stretching the warp threads of the belt portion that the resulting coefficients of elongation at break of the warp threads of the said element are greater than those of the warp threads of the belt portion by at least substantially the percentage b.
Claim 11
Dependent Claim
95 words
Belting according to claim 1, wherein the belt portion and said element are woven from warp threads whose coefficients of elongation at break originally differed by a percentage different from the percentage b, but which, before weaving, have been treated by so shrinking the warp threads of the said element and so stretching the warp threads of the belt portion that the resulting coefficients of elongation at break of the warp threads of the said element are greater than those of the warp threads of the belt portion by at least substantially the percentage b.
Claim 12
Dependent Claim
51 words
Belting according to claim 1, wherein the warp threads or the plys thereof, of said element have a different degree of twist to the warp threads, or the plys thereof, of the belt portion, the differences in the degrees of twist being such as to provide said different coefficients of elongation.
Claim 13
Dependent Claim
20 words
Belting according to claim 4, wherein the protective profiled element has half the weft density of the woven belt portion.
Claim 14
Dependent Claim
19 words
Belting according to claim 6, wherein the belt portion has a -- weave with double weft insertion per shedding.
Claim 15
Dependent Claim
34 words
Belting according to claim 11, wherein the warp threads, or the plys thereof, of said element are twisted to a greater extent than the warp threads, or the plys thereof, of the belt portion.
Claim 16
Dependent Claim
69 words
Woven belting for safety belts including: a woven flat single layer belt portion having integral opposite side rims in the form of tube portions, said belt and tube portions having warp and weft threads, the dimensions and coefficients of elongation at break of the warp threads of both the said belt and tube portions being predetermined so that they are chargeable up to about the same charge of break.
Claim 17
Dependent Claim
69 words
Woven belting for safety belts including: a woven flat single layer belt portion having integral opposite side rims in the form of tube portions, said belt and tube portions having warp and weft threads, the dimensions and coefficients of elongation at break of the warp threads of both the said belt and tube portions being predetermined so that they are chargeable up to about the same charge of break.
