When the deck lid 14 has been moved to a partially
frame 36 and the other end pivoted at 78 to the frame 72.
A pair of detent levers 8t} and 82 are coaxially mounted at 10 open position adjacent its fully closed position, the bolt
84 on the frame 72. A coil torsion spring 86 mounted on
the pivot 84 has one end thereof hooked under one of the
legs of lever 32 and the other end 99 thereof hooked over
an offset of one leg of lever 80 so as to hold the one
leg of lever 82 in engagement with the offset of the one
leg of the lever 89. Lever 82 includes a detent foot 92
which is adapted to engage a detent shoulder 94 of the
lever 58 when the striker assembly is in a retracted posi-'
tion, as shown in FIGURES 4 and 7, and lever 80 in
cludes a detent foot 96 which is adapted to engage a de- '
tent shoulder 98 of lever 53 when the striker assembly is
in an extended position, as shown in FIGURES 2 and 3.
A spring 106 having one end hooked within an opening
102 of frame 72 and the other end hooked over a notched
lateral tab 104 of lever 80 biases the levers 80 and 82
counterclockwise at all times.
As best shown in FIGURES 5 and 6 of the drawings, a
U-shaped striker support bracket 106 includes an offset
base wall 108 which is apertured so as to receive the legs
therethrough of a striker 110, with these legs being welded
134 of the latch assembly will engage the striker 110 to
move the bolt to a latched position in engagement with
the striker. When the bolt moves from an unlatched posi
tion adjacent striker 110, as shown in FIGURE 2, to a
latched position in engagement with the striker, as shown
in FIGURES 4 and 5, the bolt engages the ?ange 114 of
detent lever 80 to swing this lever and lever 82 clock
wise about the pivot 84 against the action of the spring
100. This moves the foot 96 of lever 80 out of engage
ment with the shoulder 98 of lever 53. The tension which
has been built up in spring 24 upon closing of the deck lid
is now dissipated so as to shift the cable 26 forwardly of
the body and thereby swing lever 40 counterclockwise
about pivot 42 and tension spring 44 as link 50 shifts
downwardly and swings lever 58 counterclockwise about
its pivot 60 on plate 36, since lever 58 is now released from
lever 80. As lever 53 swings counterclockwise, it will
partially fold links 64 and 68 to shift frame 72 down
wardly as link 74 swings about its pivot 76 on frame 36 to
fold relative to frame 72 and guide movement thereof.
or otherwise rigidly secured to wall 108 to each side of the
apertures therein. Bracket 106 has its side walls stacked
to the frame 72 at 112, FIGURES 3 and 7. The detent
lever 80 further includes a laterally extending flange 114
The vertical shifting movement of the frame 72 to its re
tracted position will move the deck lid 14 from partially -
which is normally located immeditaely below the open
with the striker 110.
As the frame 72 shifts downwardly and lever 53 swings
counterclockwise, the shoulder 94 of the lever will move
into engagement with the foot 92 of lever 82. Approxi
mately at the same time that the frame 72 reaches its re
tracted position, the energy stored in the spring 24 is
ing of the striker 110. As shown in FIGURE 7, a cover
116 extends around frames 72 and 36 and includes side
walls 118 bolted at 120 to offset tabs 122 of frame 36
and an apertured upper wall 124 bolted at 126 to offset
?anges 128 of the frame 36. The upper wall of cover
116 is apertured to allow the striker 110 to extend up
wardly therethrough, with the bracket 106 including a
?anged upper wall 130 which locates the cover.
When the deck lid 14 is in an open position as shown in
FIGURES l, 2 and 3, the striker 110 and frame 72 will
be in an extended position. In this position of the striker
110, the foot 96 of lever 80 engages the shoulder 98 of
open to fully closed position in sealing engagement with
body 10 since the latch bolt 134 is in latching engagement
dissipated. However, prior to this dissipation of the
energy stored in the spring 24, spring 44 will have been
tensioned to store operating energy for returning frame
72 to extend position and the lever 58 will have moved
into engagement with the lever 82. The tension in spring
44 will have been built up gradually as frame 72 moves
to retracted position, with this tension tending to bias the
lever 58 under the action of spring 160 and the pin 56
lever 40 in a clockwise direction to in turn tend to shift
which interconnects lever 58 with link 50 will be at the
upper end of the arcuate slot 59, with the foot 54' of link '
50 being in engagement with a bumper 132 secured to
frame 36. The spring 44 interconnecting lever 40 and
frame 36 is under very slight tension and biases the lever
40 clockwise so as to hold link 50 in engagement with the
bumper 132 and to locate lever 58 so that the shoulder
98 thereof will be in position in engagement with the foot
96 of lever 80. Cable 26 which extends between the spring
24 and lever 49 will be taut in the sense that there will
be no slack in the cable, although the spring 24 will be in
free position and will not be under tension.
Assume now that the deck lid 14 is moved toward closed
link 50 upwardly. This action of the spring 44 is re
sisted by the detent engagement of the levers 53 and 82
and the engagement of bolt 134 with ?ange 114 which pre~
vents counterclockwise swinging movement of levers 80
and 82.
If the detent which holds the bolt 134 is thereafter
tripped to allow the bolt to be moved to an unlatched
position, the movement of the bolt out of engagement
with the ?ange 114 of lever 80 will allow spring 100 to
bias levers 80 and 82 counterclockwise about the pivot
position. As the deck lid moves toward closed position, it
84 so as to move the foot 92 of lever 82 out of engage
ment with the shoulder 94 of lever 58. The tension in
spring 44 is now dissipated to swing lever 40 clockwise
about pivot 42 ‘and shift link 50 upwardly as lever 58
swings clockwise about its pivot 60 on plate 36 to unfold
links 64 and 68 and thereby shift the frame 72 upwardly
and move the striker 110 to its extended position as the
link 74 now swings clockwise about its pivot 76 on frame
36. This movement of frame 72 and striker 110 to ex
will engage the roller 22 to swing lever 18 clockwise as
viewed in FIGURE 1 about its pivot 20 on the body. This
will tension the spring 24 between the lever and the cable
26. The tension in spring 24 will gradually be built up
against lever 58 as the deck lid 14 moves toward its closed
position so as to store operating energy for moving frame
tended position occurs as the deck lid 14 moves to a

Although not shown in detail in the drawings, a suitable

latch assembly is mounted on the rearward edge of the
spring 100 until the shoulder 98 of the lever 58 engages
deck lid 14 in a position so as to engage the striker 110.

ment of the'frame 72 and locate the frame 72 and striker
110 in extended position.
As the operating energy stored in spring 44 is dissipated
to move-frame 72 and striker 110 to extended position,
the clockwise swinging movement of lever 40 maintains
cable 26 taut and thereby swings lever =18 to its generally
upright position, as shown in FIGURE 1, preparatory
to the start of another'cycle of operation.
Thus, this. invention provides a new'and improved
vehicle closure latch which includes striker means mov
able between extended and retracted positions, with the
striker means cooperating with a latch assembly to move
a vehicle closure between partially open and fully closed
positions.
