1. A temporary latch releasing mechanism for a springurged latch pivotally mounted on an upper channel member adapted for forward and rearward movement along a lower channel member of an adjuster mechanism of a seat having a back pivotally mounted for tilting, comprising:
- a latch release blade pivotally mounted on the upper channel member for movement toward and away from a predetermined position at which the latch release blade releases the springurged latch;
a bell-crank detent pivotally mounted on the upper channel member, the bell-crank detent having a trigger arm;
operating means for moving, upon movement of the back when the back is tilted forward, the latch release blade to the predetermined position;
means biasing the bell-crank detent in a predetermined direction to lock the latch release blade in the predetermined position when the latch release blade is moved to the predetermined position and the latch release blade away from the predetermined position; and
detent release means for moving the trigger arm in an opposite direction to the predetermined direction to unlock the latch release blade when the trigger arm is moved by the detent release as a result of rearward movement of the upper channel member relative to the lower channel member.

Abstract
A latch release blade is provided with a bellcrank detent both mounted on an upper channel of fore and aft adjuster. A lever and link mechanism shifts, upon tilting the back forward, the latch release blade until locked by the detent to release the upper channel for forward movement along a lower channel. A detent release assembly is mounted on the lower channel to shift the detent to unlock the latch release blade.

7. In a seat having a back pivotally mounted for tilting a lower channel member having a struckup blade formed with spaced notches;
-
an upper channel member supporting the seat, the upper channel member being mounted on the lower channel member for forward and rearward movements along the lower channel member; a latch pivotally mounted to the upper channel member, the latch being spring biased to engage with one of the spaced notches of the struckup blade; a latch release blade pivotally mounted on the upper channel member for rotation toward and away from a predetermined position at which the latch release blade disengages the latch from the struckup blade to release the upper channel member for forward and rearward movements along the lower channel member; a bell-crank detent pivotally mounted on the upper channel member, the bell-crank detent having a trigger arm; means responsive to movement of the back when the back is tilted forward for rotating the latch release blade toward the predetermined position; means for biasing the bell-crank detent in a predetermined direction to lock the latch release blade in the predetermined position when the latch release blade is rotated to the predetermined position and the latch release blade away from the predetermined position; and detent release means mounted to the lower channel member, the detent release means includes a portion disposed in the path of the trigger arm so that the portion rotates the trigger arm in an opposite direction to the predetermined direction when the trigger arm is moved by the portion during rearward movement of the upper channel member relative to the lower channel member and the portion is moved by the trigger arm out of the path of the trigger arm when the trigger arm moves past the portion during forward movement of the upper channel member relative to the lower channel member.
