Regarding equipment.

b. Prior art and its problems For example, such a locking device is disclosed in Japanese Patent Application Publication No. 2003-120002. -/4t
There is a publication No. 9jrJj.

However, such a locking device is complicated and consists of a large number of components, making it expensive, and furthermore, once a failure occurs in the link system, it cannot be repaired.

In view of the conventional example, the present invention aims to simplify the structure and improve the repair performance.The present invention aims to simplify the structure and improve the repair performance. In addition, a latch member that can be freely engaged and disengaged from a striker fixed to a partition wall having an opening is provided on the back surface of the rear seat back that can be folded forward, and the latch member has a mechanism for engaging the striker with respect to the striker. The first thing to release
One end of the control member is connected, the other end of the first control member faces the passenger compartment, and a lock lever is disposed in the middle of the first control member. The other end of the control member is configured to be removable from the lock lever through a through hole in the partition wall, and one end of the co-control member is connected to the lock plate to control release of the lock lever. It is arranged near the opening of the luggage compartment.

d0 Function of the Invention Since the present invention has such a configuration, by operating the other end of the λ-th control member in the release direction, the lock plate is controlled to disengage the lock plate (-) and the first control member is released from the negative-twist engagement. By making the parts operable,
By operating the other end of the first control member facing the interior, the latch member is released from the second squid, and the other end of the three-pronged λ-th control member is moved in the locking direction, allowing the rear seat back to rotate. When the lock plate is controlled and the lock lever is engaged by the operation, even if the other end of the first control member is operated from inside the room, the lock lever will not move because it is interfering with the lock plate, and the striker will not move.
Since the latch member will come off, the rear seat back will not rotate and the luggage compartment will not open if the operation is performed only from inside the vehicle.

e. Practical Example Next, an embodiment of the present invention will be explained with reference to the drawings.

The passenger compartment and the luggage compartment are blocked off by a partition wall that connects the opening 3, and a striker is fixed to the partition wall! A latch member A that can be freely engaged and disengaged from the back side of the rear seat back 7 that can be folded forward freely

The other end of the second control member 17 is configured to be able to be engaged with and detached from the lock lever 13 via the lock lever 13, and the other end of the second control member 17 is connected to the lock plate/It to control release of the lock lever/3. The latch member has a knob /g located near the opening /9 of the luggage compartment, and the latch member is supported by a 7-yet provided on a lock base 20 fixed to the seat back 71C. A return sedge ring 21 is provided between the latch member and the lock base J (
), and the latch member g is a striker! Also, the lock plate slag is biased in the direction of engagement with the bulkhead by fixing an phantom on one side at the part indicated by reference numeral 2 on the surface of the bulkhead on the cargo compartment side, and fixing a phantom on one side on the other side. Consisting of a lock base frame j bent at right angles to the rock base frame j, and a center bin protruding horizontally from the pond surface J of the lock base frame j, the grate member 27 is easily supported rotatably in the vertical direction, The rotation of the grate member 270 is stopped by a tongue-shaped stopper 2g protruding from the other surface 2# of the lock base 7 frame j.
The tip 27a of the grate member 27 is stretched between the halved portion ga of the center bin 3 and the grate member 27 by a return spring that urges the tip portion 27a away from the lock lever 13. Furthermore, a grate 32 is engaged with the bottle 10 protruding from the grate member 27 through an elongated hole 31, and a flexible wire is connected between the end portion/A of the co-control member/7 and the knob/1. 33 and a guide pin 3μ are interposed, that is, this knob/l is provided protrudingly from the surface of the guide bin 3μ, the guide pin 3tt is retractable from the guide case J3Vca, and the Insert the knob/l into the reverse-shaped guide hole 36.
is coming. Further, since the guide pin 3tt is biased toward the one end IA side of the λ-th control member 17, that is, the one end 37 side of the guide hole 36, by a tin ring (not shown), the guide pin 3tt is biased toward the one end 37 side of the guide hole 36 with the knob it. One end portion 37
When the guide pin 73μ is slid from the other end 31 to the other end 31 and rotated downward to cut off the urging force on the knob /l, the guide pin 3μ moves together with the knob /r to the stopper portion 3 due to the sliding force. and will be retained. Further, the lock lever/3 has flanges erected on both sides, and the portion on the side that comes into pressure contact with the grate member 27 is located on the lower side [7].
A flange 4t/ is formed, and this bent curved surface λ is easily slidable between it and the curved surface of the tip 27a of the grate member 27. Further, between the third control member part 10 and each latch member, the shaft/
In addition to this, one end portion 10 is supported by a pin 4tj with a link rating of 4t.
