Abstract
Abstract Self-locking belt wind-up device for safety belts including rotatable cylinder means whereon a safety belt is windable, and a unitary assembly of a bearing block, a pendulum pendulously supported by the bearing block, and a locking lever pivotally supported on the bearing block and engageable by the pendulum for pivoting into a position wherein it is in engagement with the cylinder means and locks the latter against rotation.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
88 words
Self-locking belt wind-up device for safety belts comprising rotatable cylinder means whereon a safety belt is windable, and a unitary assembly of a bearing block, a pendulum pendulously supported by said bearing block, and a locking lever pivotally supported independently of said pendulum on said bearing block, said pendulum having a mass on the normally lower end thereof, said locking lever being engageable by said mass and being pivotable thereby into a position wherein it is in engagement with said cylinder means and locks the latter against rotation.
Claim 2
Dependent Claim
88 words
Self-locking belt wind-up device for safety belts comprising rotatable cylinder means whereon a safety belt is windable, and a unitary assembly of a bearing block, a pendulum pendulously supported by said bearing block, and a locking lever pivotally supported independently of said pendulum on said bearing block, said pendulum having a mass on the normally lower end thereof, said locking lever being engageable by said mass and being pivotable thereby into a position wherein it is in engagement with said cylinder means and locks the latter against rotation.
Claim 3
Dependent Claim
113 words
Self-locking belt wind-up device for safety belts comprising rotatable cylinder means whereupon a safety belt is windable, and a unitary assembly of a bearing block, a pendulum pendulously supported by said bearing block, and a locking lever pivotally supported on said bearing block and engageable by said pendulum for pivoting into a position wherein it is in engagement with said cylinder means and locks the latter against rotation, said pendulum having a free end, and including an inertial mass mounted on said free end of said pendulum, said inertial mass having a lower surface formed in the shape of a cup, one end of said pivotable locking lever being receivable in said cup.
Claim 4
Dependent Claim
113 words
Self-locking belt wind-up device for safety belts comprising rotatable cylinder means whereupon a safety belt is windable, and a unitary assembly of a bearing block, a pendulum pendulously supported by said bearing block, and a locking lever pivotally supported on said bearing block and engageable by said pendulum for pivoting into a position wherein it is in engagement with said cylinder means and locks the latter against rotation, said pendulum having a free end, and including an inertial mass mounted on said free end of said pendulum, said inertial mass having a lower surface formed in the shape of a cup, one end of said pivotable locking lever being receivable in said cup.
Claim 5
Dependent Claim
31 words
Self-locking belt wind-up device according to claim 2 wherein said pendulum has a shaft, and including means for adjusting the position of said inertial mass along the length of said shaft.
Claim 6
Dependent Claim
35 words
Self-locking belt wind-up device according to claim 3 wherein said adjusting means comprises an externally threaded portion formed on said pendulum shaft and threadedly received in an internally threaded bore formed in said inertial mass.
