Fig. 8 and Fig. 9 are the birds-eye vieies that the state of lever part and linkage component when making tilt adjustment device 12 carry out jackknife action is shown.Fig. 9 is illustrated in and carries out decontroling control lever 28 behind the jackknife action, makes it return the state of initial position.As shown in Figure 8, in case tractive control lever 28, the 2 lever parts 24 are by drop-down upward, by the action interlock of ladder pin 26 bonded assemblys the 1st lever part 22 and the 2nd lever part 24, clockwise direction rotates among the figure that is disengaged along the locking of tilt adjustment unit 17.Be unlocked by tilt adjustment unit 17, the 1st carriage 15 and the chair back 2 that is installed on the 1st carriage 15 are turned forward.
At this, at the 2nd lever part 24 when drop-down, the ladder pin 37 that inserts in the slotted hole 24b is moved with the state of ladder pin 37 along the へ font hole of the 2nd carriage 16 to oblique below, because ladder pin 37 breaks away from from the movement locus of flange part 15a, leaning forward of the 1st carriage 15 is unrestricted, and the chair back 2 is poured onto the state with seat cushion 3 approximate horizontal.At this moment, the 2nd linkage component 36 that ladder pin 37 has been installed is along with ladder pin 37 moving to oblique below, slide and center on turning cylinder 35 and rotate, and the combination of the notch 34b of sweep 36b and the 1st linkage component 34 disconnects, therefore the 1st linkage component 34 can not rotate, and the sliding locking mechanism of seat slide device can not be disengaged.
After making the fold mechanism start, even operate advancing mechanism, because under the state of as shown in Figure 9 relieving control lever 28, except that the 1st carriage 15, all return to common state shown in Figure 4, even therefore the described wirerope 23 of tractive also can only switch the locking and unlocking state by the lockout mechanism of tilt adjustment unit 17.Just as described in reference to figure 7, the upwards tractive of removing the wirerope 33 of sliding locking mechanism only can carry out when flange part 15a contacts with ladder pin 37 by leaning forward of the 1st carriage 15.Therefore, can not remove the sliding locking mechanism of seat slide device 11, can prevent maloperation.
