抜け止めされている。As shown in detail in FIGS. 6 and 7, the lock mechanism 30 includes a lock pin 31, a coil spring 32, a pair of upper and lower spring receivers 33 and 34, and a stopper ring 35.
A guide pin 36 is planted at the upper end of the lock pin 31. On the other hand, the upper seat back frame 1
A guide slit 14a extending upward from the opening is formed on the outer periphery of the lower left end of the guide groove 4, and an engaging recess 14b is continuously provided at the upper end of the guide slit 14a. A long hole 14c is formed above the upper end of the guide slit 14a along the circumferential direction, and the upper spring receiver 33 is fitted in the long hole 14c. The coil spring 32, the lower spring receiver 34, and the lock pin 31 are inserted from the opening at the lower left corner of the upper seatback frame 14,
The guide pin 36 is slidably fitted in the guide slit 14a. Furthermore, the upper seat back frame 14
A stopper ring 35 is fitted on the outer periphery of the lower end of the lock pin 31, and the lock pin 31 urged downward by the coil spring 32 is prevented from coming off by the guide pin 36 contacting the upper end of the stopper ring 35.

る。Since the lock mechanism 30 has such a structure, as shown in FIG.
When 6 is in contact with the stopper ring 35, it projects from the lower end opening of the upper seat back frame 14 and fits into the upper left side opening of the lower seat back frame 15, whereby the upper seat back frame 14 is locked to the lower seat back frame 15. It On the other hand, if the guide pin 36 is lifted upward along the guide slit 14a against the spring force of the coil spring 32, the lock pin 31
Is disengaged from the upper end opening of the lower seat back frame 15, so that the upper seat back frame 14 is unlocked. Further, the lock release state can be maintained by engaging the guide pin 36 with the engagement recess 14b.

く振り返ることができる。When the seated person looks back and picks up luggage from the rear seat or wants to confirm the rear view, the guide pin 36 is lifted against the spring 32 and engaged in the engaging recess, so that the lock pin 31 is moved to the lower seat. Since the upper seat back 11 is disengaged from the back frame 15, the upper seat back 11 can rotate in the front-rear direction with the bolt 16 as a fulcrum. Therefore, when the left side portion of the upper seat back 11 is pushed backward by the back, the upper seat back 11 is twisted as shown in FIG. 2, so that the seated person can look back without being disturbed by the seat back SB.

Then, when the guide pin 36 is removed from the engagement recess, the lock pin 31 is lowered by the spring force of the spring 32 and fitted into the lower seat back frame 15. As a result, the upper seat back 11 is locked to the lower seat back 12.

できる。As described above, according to this embodiment, the seat back SB of the vehicle seat is replaced by the upper seat back 1
1 and the lower seat back 12 are divided into upper and lower parts, and the upper seat back 11 is assembled so as to be rotatable in the front-rear direction with a bolt 16 provided at an intermediate portion of the lower seat back 12 as a fulcrum, so that a passenger is seated. Release the lock by the lock mechanism 30 and look back, the coil spring 28,
29 The upper seat back rotates 11 backwards against the spring force. For this reason, the operation of checking the rear view while taking the luggage of the rear seat while seated is the seat back SB.
It's easy because it's not disturbed. Further, since the bolt 16 that serves as the center of rotation of the upper seat back 11 is provided in the middle portion of the lower seat back 12, the occupant can look back to either the left or right side. Furthermore, the stopper plate 23
Since the amount of rotation of the upper seat back is limited by the ring plate 22, it is possible to prevent the posture from collapsing when turning back.
