Abstract
Abstract In a safety belt, the belt anchorage after the webbing has been duly fitted around the user''s body leaves a certain freedom of movement to the user until the driver depresses the brake pedal, thus causing the selected power means, whether of electrical, pneumatic, hydraulic or mechanical character, to cause the positive engagement of a pawl associated with one end of the webbing into a perforation formed in a member associated with the other end of the webbing, so as to lock the webbing around the user''s body on this side of the amplitude allowed by the initial resilient anchorage.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
172 words
A safety belt anchoring device for use with safety belts for passengers in vehicles comprising: a seat belt webbing, a fastener for anchoring a belt end and a base plate one end of which is adapted for anchoring the belt end to a point in a vehicle; slide means fixed to said fastener and movable on said base plate for moving said fastener, and means in said base plate for guiding said slide means when moving along said base plate; resilient reaction springs for connecting said belt fastener to said one end of the base plate and permitting a certain amplitude of free movements by the passenger; a pivoting pawl fixed on said base plate and having a hook portion for locking said slide means by engaging said hook in perforations in said slide means; control means for activating said pawl for locking said slide means in response to a sudden deceleration of the vehicle, and resilient means for returning said pawl to its normal position wherein said slide means is unlocked.
Claim 2
Dependent Claim
172 words
A safety belt anchoring device for use with safety belts for passengers in vehicles comprising: a seat belt webbing, a fastener for anchoring a belt end and a base plate one end of which is adapted for anchoring the belt end to a point in a vehicle; slide means fixed to said fastener and movable on said base plate for moving said fastener, and means in said base plate for guiding said slide means when moving along said base plate; resilient reaction springs for connecting said belt fastener to said one end of the base plate and permitting a certain amplitude of free movements by the passenger; a pivoting pawl fixed on said base plate and having a hook portion for locking said slide means by engaging said hook in perforations in said slide means; control means for activating said pawl for locking said slide means in response to a sudden deceleration of the vehicle, and resilient means for returning said pawl to its normal position wherein said slide means is unlocked.

Claim 4
Dependent Claim
55 words
A safety belt anchoring device according to claim 1, wherein said control means for activating said pawl comprises an electromagnet having a solenoid energized by an electrical system for activation upon sudden deceleration of a vehicle, said electromagnet having a movable core connected to said pawl for pivoting said pawl for locking said slide means.
Claim 5
Dependent Claim
29 words
A safety belt anchoring device according to claim 1, wherein said control means includes an inertia switch for energizing said control means upon a sudden deceleration of a vehicle.
