Abstract
Abstract The device clamps the safety belt between a fixed plate and a movable member which is connected to the plate by pivotable links which are biased by resiliently yieldable means to a position for urging the movable member against the belt. A pull on the belt which unwinds the belt from a belt winder shifts the movable member in a direction to pivot the links in such direction that they clamp the movable member still more forcefully against the belt.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
223 words
A locking device in particular for a safety belt secured at one end to a winder, the device comprising a fixed plate and a movable member defining a gap for the belt, links pivoted to the plate and to the movable member interconnecting the plate and movable member, the links being movable between a first position in which the movable member is in a position relative to the plate to allow the belt to move freely and a second position in which the gap between the movable member and plate is less than the thickness of the belt, resiliently yieldable means cooperative with the links and biasing the links toward said second position thereof, movement of the links from said first position toward said second position being in such direction that when the belt is pulled in a direction to cause the unwinding of the belt there is an increase in the clamping of the movable member against the belt and fixed plate, and actuating means for shifting the movable member away from the fixed plate and thereby releasing the belt, said actuating means comprising an electromagnet having a moving armature, an electric circuit controlling the electromagnet, means connecting the armature to the links, the armature being adapted to act on the links in opposition to the action of the resiliently yieldable means.
Claim 2
Dependent Claim
223 words
A locking device in particular for a safety belt secured at one end to a winder, the device comprising a fixed plate and a movable member defining a gap for the belt, links pivoted to the plate and to the movable member interconnecting the plate and movable member, the links being movable between a first position in which the movable member is in a position relative to the plate to allow the belt to move freely and a second position in which the gap between the movable member and plate is less than the thickness of the belt, resiliently yieldable means cooperative with the links and biasing the links toward said second position thereof, movement of the links from said first position toward said second position being in such direction that when the belt is pulled in a direction to cause the unwinding of the belt there is an increase in the clamping of the movable member against the belt and fixed plate, and actuating means for shifting the movable member away from the fixed plate and thereby releasing the belt, said actuating means comprising an electromagnet having a moving armature, an electric circuit controlling the electromagnet, means connecting the armature to the links, the armature being adapted to act on the links in opposition to the action of the resiliently yieldable means.
Claim 3
Dependent Claim
36 words
A device as claimed in claim 1, wherein the movable member carries a layer of a material having a high coefficient of friction through which layer the movable member exerts its clamping action on the belt.
Claim 4
Dependent Claim
31 words
A device as claimed in claim 1, wherein the resiliently yieldable means comprise a spring having one end connected to the plate and another end connected to one of the links.
Claim 5
Dependent Claim
51 words
A device as claimed in claim 1, comprising a first abutment integral with the fixed plate and a second abutment which is integral with the movable member and is co-operative with the first abutment for defining an end of-travel position of the movable member in a direction away from the plate.
Claim 6
Dependent Claim
40 words
A device as claimed in claim 1, wherein the fixed plate has a U shape with end flanges and defines a substantially rectangular surface for contacting the belt, the movable member being a plate also having a substantially rectangular shape.
Claim 7
Dependent Claim
19 words
A device as claimed in claim 1, wherein the fixed plate comprises means for laterally guiding the movable member.
Claim 8
Dependent Claim
48 words
A device as claimed in claim 6, wherein the guide means caarry a first abutment, and a second abutment is integral with the movable member and is co-operative with the first abutment for defining an end-of-travel position of the movable member in a direction away from the plate.
Claim 9
Dependent Claim
206 words
A structure comprising, in a vehicle: a safety belt having a first portion connected to a belt winder and a second portion connected to means for hooking the belt to a fixed part of the vehicle, and a belt locking device fixed to the vehicle and combined with the belt in a position intermediate said first and second portions, said device comprising a fixed plate and a movable member defining a gap for the belt, links pivoted to the plate and to the movable member interconnecting the plate and movable member, the links being movable between a first position in which the movable member is in a position relative to the plate to allow the belt to move freely and a second position in which the gap between the movable member and plate is less than the thickness of the belt, resiliently yieldable means cooperative with the links and biasing the links toward said second position thereof, movement of the links from said first position toward said second position being in such direction that when the belt is pulled in a direction to cause the unwinding of the belt there is an increase in the clamping of the movable member against the belt and fixed plate.
Claim 10
Dependent Claim
206 words
A structure comprising, in a vehicle: a safety belt having a first portion connected to a belt winder and a second portion connected to means for hooking the belt to a fixed part of the vehicle, and a belt locking device fixed to the vehicle and combined with the belt in a position intermediate said first and second portions, said device comprising a fixed plate and a movable member defining a gap for the belt, links pivoted to the plate and to the movable member interconnecting the plate and movable member, the links being movable between a first position in which the movable member is in a position relative to the plate to allow the belt to move freely and a second position in which the gap between the movable member and plate is less than the thickness of the belt, resiliently yieldable means cooperative with the links and biasing the links toward said second position thereof, movement of the links from said first position toward said second position being in such direction that when the belt is pulled in a direction to cause the unwinding of the belt there is an increase in the clamping of the movable member against the belt and fixed plate.
Claim 11
Dependent Claim
49 words
A structure as claimed in claim 8, wherein the winder is located in a lower part of a post of the vehicle whereas the locking device is located in the vicinity of an upper part of the post, the belt extending through guide means disposed above the locking device.
