Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
189 words
A device for the tightening of a belt forming part of a safety harness assembly of a safety belt for vehicles in case of abnormal changes of speed of the vehicle, as for example during a collision, comprising a safety belt part, a sensor means capable of sensing said abnormal speed changes and giving off a gaseous pressure pulse in its activated condition, a power means capable of being driven by said gaseous pressure pulse and in its activated condition capable of giving at least one portion of said belt part a movement in a sidewards direction relative to the normal extension of said belt part thus forming at least one sidewards directed loop, said power means comprises a number of gas charges which can expand and said belt part having inner spaces along the longitudinal direction of said belt to be tightened, said charges being arranged in said belt inner spaces with at least one of the sides of said charges being adjacent said belt in such a way that said belt is deflected sidewise thereby contracting in the pulling direction when any of said charges are activated.
Claim 2
Independent Claim
189 words
A device for the tightening of a belt forming part of a safety harness assembly of a safety belt for vehicles in case of abnormal changes of speed of the vehicle, as for example during a collision, comprising a safety belt part, a sensor means capable of sensing said abnormal speed changes and giving off a gaseous pressure pulse in its activated condition, a power means capable of being driven by said gaseous pressure pulse and in its activated condition capable of giving at least one portion of said belt part a movement in a sidewards direction relative to the normal extension of said belt part thus forming at least one sidewards directed loop, said power means comprises a number of gas charges which can expand and said belt part having inner spaces along the longitudinal direction of said belt to be tightened, said charges being arranged in said belt inner spaces with at least one of the sides of said charges being adjacent said belt in such a way that said belt is deflected sidewise thereby contracting in the pulling direction when any of said charges are activated.
Claim 3
Dependent Claim
45 words
Device according to claim 1, including two band shaped sheet metal strips extending in the longitudinal direction of said belt part and forming an extension of the same which strips are held together at points located therealong and said charges being positioned between said points.
Claim 4
Dependent Claim
50 words
Device according to claim 1 including a tube forming an extension of said belt and containing a number of compartments in between them separated by tranversally extending walls each one containing one of said charges, and the wall portion of said tube defining said compartments having a number of slits.
Claim 5
Dependent Claim
15 words
Device according to claim 1, including controlling means arranged to activate said charges in series.
Claim 6
Dependent Claim
34 words
Device according to claim 4, including means for feeling the weight of the person sitting on the seat in question so adjusted that a number of said charges corresponding to the weight are activated.
Claim 7
Dependent Claim
16 words
Device according to claim 5, wherein said feeling devices being arranged to work with a delay.
Claim 8
Independent Claim
190 words
A device for the tightening of a belt forming part of a safety harness assembly of a safety belt for vehicles in case of abnormal changes of speed of the vehicle, as for example during a collision, comprising a safety belt part, a sensor means capable of sensing said abnormal speed changes and giving off a gaseous pressure pulse in its activated condition, a power means capable of being driven by said gaseous pressure pulse and in its activated condition capable of giving at least one portion of said belt part a movement in a sidewards direction relative to the normal extension of said belt part thus forming at least one sidewards direction loop, a number of fixed transverse guide bridges interspaced in the longitudinal direction of said belt part and extending crosswise relative to said belt part, a number of gas containers positioned between said guide bridges which are positioned at the one side of said belt and arranged in such a way that in their expanded condition they can press out a portion of said belt part between said guide bridges thus producing a tightening of said belt.
Claim 9
Independent Claim
190 words
A device for the tightening of a belt forming part of a safety harness assembly of a safety belt for vehicles in case of abnormal changes of speed of the vehicle, as for example during a collision, comprising a safety belt part, a sensor means capable of sensing said abnormal speed changes and giving off a gaseous pressure pulse in its activated condition, a power means capable of being driven by said gaseous pressure pulse and in its activated condition capable of giving at least one portion of said belt part a movement in a sidewards direction relative to the normal extension of said belt part thus forming at least one sidewards direction loop, a number of fixed transverse guide bridges interspaced in the longitudinal direction of said belt part and extending crosswise relative to said belt part, a number of gas containers positioned between said guide bridges which are positioned at the one side of said belt and arranged in such a way that in their expanded condition they can press out a portion of said belt part between said guide bridges thus producing a tightening of said belt.
Claim 10
Dependent Claim
15 words
A device as claimed in claim 7 wherein said guide bridges are each a pin.
Claim 11
Dependent Claim
26 words
A device as claimed in claim 7 wherein said power means is a bellows and said sensor means includes an electrically operable charge in said bellows.
