Abstract
Abstract Electric locks of the armed type comprise a movable bolt assembly actuated by various levers, powered by a motorized reduction gear assembly and capable of hooking a keeper mounted on a stationary part of the body. The bolt assembly comprises a locking lever of a keeper and a blocking lever of the locking lever, both biased in the hooked position by a common spring. A rotating control body controls the preceding levers, and rotates successively in the opening direction and in the reverse closing direction while being powered by a motorized reduction assembly in response to the impulses of electric current.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
203 words
An electric locking device for a vehicle closure, said locking device comprising: a keeper mounted on a first portion of said vehicle; a movable bolt assembly mounted on a second portion of said vehicle, said second portion being movable relative to said first portion; a motorized reversible reduction gear assembly mounted on said bolt assembly and including a rotatable shaft; a control body mounted on said rotatable gear assembly shaft, said control body being mounted for pivoting about an axis perpendicular to said shaft; a locking lever pivotally mounted on said bolt assembly, including a first portion engageable with said control body for moving said locking lever into a first position in engagement with said keeper; a blocking lever pivotally mounted on said bolt assembly, said blocking lever including a first portion engageable, in a first position thereof, with said locking lever in said first position thereof for blocking movement of said locking lever from said first position thereof, and a second portion engageable with said control body for moving said blocking lever out of said first position thereof; and first spring means biasing said locking lever out of said first position thereof and biasing said blocking lever into said first position thereof.
Claim 2
Dependent Claim
203 words
An electric locking device for a vehicle closure, said locking device comprising: a keeper mounted on a first portion of said vehicle; a movable bolt assembly mounted on a second portion of said vehicle, said second portion being movable relative to said first portion; a motorized reversible reduction gear assembly mounted on said bolt assembly and including a rotatable shaft; a control body mounted on said rotatable gear assembly shaft, said control body being mounted for pivoting about an axis perpendicular to said shaft; a locking lever pivotally mounted on said bolt assembly, including a first portion engageable with said control body for moving said locking lever into a first position in engagement with said keeper; a blocking lever pivotally mounted on said bolt assembly, said blocking lever including a first portion engageable, in a first position thereof, with said locking lever in said first position thereof for blocking movement of said locking lever from said first position thereof, and a second portion engageable with said control body for moving said blocking lever out of said first position thereof; and first spring means biasing said locking lever out of said first position thereof and biasing said blocking lever into said first position thereof.
Claim 3
Dependent Claim
80 words
