Abstract
Abstract Deflection device for a safety belt with a bar around which the safety belt passes, a pivotable arm in which the bar can slide in a direction transverse to the longitudinal extension of the belt and a stop for the bar, the arrangement being such that the belt can normally pass freely around the bar from the belt collector but that the belt becomes clamped between the bar and the stop when subjected to abnormal forces, such as a collision or extreme deceleration.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
143 words
A deflection device for a safety belt arrangement including a belt and belt collecting means, comprising: a bracket to be connected to a part of a vehicle, a bar about which a belt is adapted to pass, a stop, said bar being movable in a direction towards and away from said stop, an arm pivotally supporting said stop about an axis transverse to the longitudinal extension of a belt passed around said bar, said bar being movable along said arm in said transverse direction, said bar and stop being arranged to permit the belt to run free about said bar when the belt is subjected to a force at least equivalent to the collecting force of said collecting means under normal conditions of use, and to lock the belt between said bar and said stop when the belt is subjected to abnormal forces.
Claim 2
Dependent Claim
143 words
A deflection device for a safety belt arrangement including a belt and belt collecting means, comprising: a bracket to be connected to a part of a vehicle, a bar about which a belt is adapted to pass, a stop, said bar being movable in a direction towards and away from said stop, an arm pivotally supporting said stop about an axis transverse to the longitudinal extension of a belt passed around said bar, said bar being movable along said arm in said transverse direction, said bar and stop being arranged to permit the belt to run free about said bar when the belt is subjected to a force at least equivalent to the collecting force of said collecting means under normal conditions of use, and to lock the belt between said bar and said stop when the belt is subjected to abnormal forces.
Claim 3
Dependent Claim
23 words
A deflection device according to claim 1, wherein said stop is located on the side of the bar facing away from said axis.
Claim 4
Dependent Claim
82 words
A deflection device accordng to claim 1, wherein said arm is pivotable between a normal position, in which the resultant force exerted by a belt passed around said bar on said bar forms an angle of not substantially less than 90 degrees, with a line along said arm in a direction towards said stop, the apex of said angle substantially coinciding with said bar, and a locking position, in which the angle between the resultant force and said line is relatively acute.
Claim 5
Dependent Claim
28 words
A deflection device according to claim 1, comprising means holding said arm in said normal position until the resultant force exceeds the collecting force of the collecting means.
Claim 6
Dependent Claim
20 words
A deflection device according to claim 4, wherein said holding means comprises at least one snap lock for said arm.
Claim 7
Dependent Claim
24 words
A deflection device according to claim 4, wherein said holding means comprises a spring constantly urging said arm to pivot to its normal position.
Claim 8
Dependent Claim
57 words
A deflection device according to claim 4, wherein said holding means comprises a snap lock for said arm, and a spring constantly urging said arm to pivot to its normal position, the force of said spring exceeding the force required for causing said arm to be engaged by said snap lock when returning to said normal position.
Claim 9
Dependent Claim
25 words
A deflection device according to claim 1, wherein said arm forms a substantially U-shaped body with two legs, and an intermediate portion forming said stop.
Claim 10
Dependent Claim
30 words
A deflection device according to claim 8, wherein said legs of said arm each have a U-shaped cross section, end portions of said bar being slideably guided in said legs.
