Abstract
Abstract A closure latch having a latch bolt movable between latched and unlatched positions, a detent for holding the bolt against movement to the unlatched position, inside release means, outside release means, an intermittent member movable to any one of at least two positions for selectively coupling both the inside and outside release means to the detent in the first position of the intermittent member and coupling only the outside release means to the detent in the second position of the intermittent member. The detent includes a member to shift the intermittent member upon shifting of the bolt caused by movement of the bolt toward the latched position whereby the intermittent member is automatically shifted to its second position without requiring the operator to exert any conscious effort when the door is closed.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
141 words
A closure latch for a vehicle door comprising, in combination, a latch bolt movable between latched and unlatched positions, detent means for holding the bolt against movement to the unlatched position, inside release means, outside release means, an intermittent member movable to one of at least two positions for selectively coupling both the inside and outside release means to the detent means in a first position of the intermittent member and coupling only the outside release means to the detent means in a second position of the intermittent member, said detent means comprising a member to shift the intermittent member upon shifting of the latch bolt caused by movement of the bolt toward latched position whereby the intermittent member is automatically shifted to its second position without requiring the operator to exert any conscious effort when the vehicle door is closed.
Claim 2
Dependent Claim
141 words
A closure latch for a vehicle door comprising, in combination, a latch bolt movable between latched and unlatched positions, detent means for holding the bolt against movement to the unlatched position, inside release means, outside release means, an intermittent member movable to one of at least two positions for selectively coupling both the inside and outside release means to the detent means in a first position of the intermittent member and coupling only the outside release means to the detent means in a second position of the intermittent member, said detent means comprising a member to shift the intermittent member upon shifting of the latch bolt caused by movement of the bolt toward latched position whereby the intermittent member is automatically shifted to its second position without requiring the operator to exert any conscious effort when the vehicle door is closed.
Claim 3
Dependent Claim
32 words
A closure latch as set forth in claim 1 wherein the intermittent member is movable to a third position for uncoupling both the inside and outside release means from the detent means.
Claim 4
Dependent Claim
78 words
A closure latch as set forth in claim 2 wherein, the detent means comprises a second member to shift the intermittent member from its third position to the second position upon shifting of the detent means caused by latching movement of the bolt thereby to automatically shift the intermittent member from the third position to the second position so that the outside release means is coupled to the detent means to prevent the closure latch from keyless locking.
Claim 5
Dependent Claim
119 words
A closure latch as set forth in claim 2 wherein, the outside release means includes a first lever, the inside release means includes a second lever, and the intermittent member includes a third lever pivotably connected to said first lever and including a foot and a tab, said foot being so secured on said third lever that it may occupy three positions and may selectively be in juxtaposition with both the detent means and said second lever, with only said detent means, and out of juxtaposition with both said second lever and the detent means, said tab being so secured on the said third lever that the detent means abuts against the tab upon its shifting to latched position.
Claim 6
Dependent Claim
141 words
A closure latch for a vehicle door comprising, in combination, a latch boLt movable between latched and unlatched positions, detent means for holding the bolt against movement to the unlatched position, inside release means, outside release means, an intermittent member, movable to one of two positions for selectively coupling both the inside and outside release means to the detent means in the first position of the intermittent member and uncoupling both the inside and outside release means from the detent means in the second position of the intermittent member, said detent means comprising a member to shift the intermittent member upon shifting of the latch bolt caused by movement of the bolt toward latched position whereby the intermittent member is automatically shifted to the second position without requiring the operator to exert any conscious effort when the vehicle door is closed.
Claim 7
Dependent Claim
141 words
A closure latch for a vehicle door comprising, in combination, a latch boLt movable between latched and unlatched positions, detent means for holding the bolt against movement to the unlatched position, inside release means, outside release means, an intermittent member, movable to one of two positions for selectively coupling both the inside and outside release means to the detent means in the first position of the intermittent member and uncoupling both the inside and outside release means from the detent means in the second position of the intermittent member, said detent means comprising a member to shift the intermittent member upon shifting of the latch bolt caused by movement of the bolt toward latched position whereby the intermittent member is automatically shifted to the second position without requiring the operator to exert any conscious effort when the vehicle door is closed.
