Abstract
Abstract An energy absorbing arrangement for a safety belt including a metal band provided with a plurality of elongated slots arranged in staggered parallel rows extending transversely to the direction of the loading of the safety belt. The slots form real tear points or desired points of separation which function to absorb or dissipate force due to impact loading of the safety belt.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
129 words
An energy absorbing arrangement comprising: a safety belt means, an energy absorbing band arranged in said safety belt means for absorbing energy resulting from an impact load on said safety belt means, said band includes spaced lateral edges, a plurality of slots provided in said band, said slots being disposed adjacent one another in a plurality of spaced parallel rows extending transversely to a loading direction of the energy absorbing band, and means defining predetermined separation points on said energy absorbing band for dissipating energy resulting from an impact load including dimensioned strips of said energy absorbing band disposed between at least some of adjacent slots in at least one of said parallel rows and between at least one of said slots and one of said spaced lateral edges.
Claim 2
Dependent Claim
129 words
An energy absorbing arrangement comprising: a safety belt means, an energy absorbing band arranged in said safety belt means for absorbing energy resulting from an impact load on said safety belt means, said band includes spaced lateral edges, a plurality of slots provided in said band, said slots being disposed adjacent one another in a plurality of spaced parallel rows extending transversely to a loading direction of the energy absorbing band, and means defining predetermined separation points on said energy absorbing band for dissipating energy resulting from an impact load including dimensioned strips of said energy absorbing band disposed between at least some of adjacent slots in at least one of said parallel rows and between at least one of said slots and one of said spaced lateral edges.
Claim 3
Dependent Claim
17 words
An arrangement according to claim 1, wherein said energy absorbing band is formed of a metallic material.
Claim 4
Dependent Claim
31 words
An arrangement according to claim 1, wherein said means defining separation points for dissipating energy are arranged on said energy absorbing hand so as to define corners of a doublerowed rhombic.
Claim 5
Dependent Claim
21 words
An arrangement according to claim 3, wherein each of said slots is elongated in a direction toward the spaced lateral edges.
Claim 6
Dependent Claim
19 words
An arrangement according to claim 4, wherein at least one constriction is provided in each of said elongated slots.
Claim 7
Dependent Claim
126 words
An energy absorbing arrangement comprising: a safety belt means, an energy absorbing band formed of a metallic material arranged in said safety belt means for absorbing energy resulting from an impact load on the safety belt means, a plurality of slots provided in said band, said slots being disposed adjacent one another in a plurality of spaced parallel rows extending transversely to a loading direction of the energy absorbing band, and means defining predetermined separation points on said energy absorbing band for dissipating energy resulting from an impact load, each of said slots is a tapered elongated slot having a substantially V-shaped configuration with the respective narrowed portions of each elongated slot being arranged in a direction toward said means defining separation points for dissipating energy.
Claim 8
Dependent Claim
126 words
An energy absorbing arrangement comprising: a safety belt means, an energy absorbing band formed of a metallic material arranged in said safety belt means for absorbing energy resulting from an impact load on the safety belt means, a plurality of slots provided in said band, said slots being disposed adjacent one another in a plurality of spaced parallel rows extending transversely to a loading direction of the energy absorbing band, and means defining predetermined separation points on said energy absorbing band for dissipating energy resulting from an impact load, each of said slots is a tapered elongated slot having a substantially V-shaped configuration with the respective narrowed portions of each elongated slot being arranged in a direction toward said means defining separation points for dissipating energy.
Claim 9
Dependent Claim
129 words
An energy absorbing arrangement comprising: a band for absorbing energy resulting from an impact load thereon, said band including spaced lateral edges, a plurality of slots provided in said band and arranged adjacent one another into a plurality of spaced parallel rows extending transversely to a loading direction of the energy absorbing band, a strip of band material being provided between adjacent slots in each of said rows and between laterally outermost slots in each row and an associated lateral edge, at least some of said strips of material having a predetermined dimension so as to define a plurality of intentional separation points of the band such that upon an impact load on said band impact energy is absorbed and dissipated by said band separating along said separation points.
Claim 10
Dependent Claim
129 words
An energy absorbing arrangement comprising: a band for absorbing energy resulting from an impact load thereon, said band including spaced lateral edges, a plurality of slots provided in said band and arranged adjacent one another into a plurality of spaced parallel rows extending transversely to a loading direction of the energy absorbing band, a strip of band material being provided between adjacent slots in each of said rows and between laterally outermost slots in each row and an associated lateral edge, at least some of said strips of material having a predetermined dimension so as to define a plurality of intentional separation points of the band such that upon an impact load on said band impact energy is absorbed and dissipated by said band separating along said separation points.
Claim 11
Dependent Claim
16 words
