Abstract

PURPOSE:To release locking with a simple structure by inserting a rod which is installed on an operating lever into the guide of a safety lever, forming a taper portion on the inserted portion of the rod, and engaging the end portion of the rod with the cam groove of a latch which is engageable/disengageable with a vehicle-body side member. CONSTITUTION:A rod 29 which is installed on an operating lever 37 is inserted into a guide 43 which is slided by a safety lever, and a taper portion 39 is formed on the inserted portion of the rod 29. A latch 23 is rotatable around a fulcrum 25, and an engaging recessed portion 21 which is engageable with a body side bar 19 as well as a cam groove 27 are formed on the latch 23. The end portion of the rod 29 is engaged with the cam groove 27. As the guide 43 is slided upward by the operation of the safety lever, the end portion 31 of the rod 29 is engaged with one 47 of the grooves 27 of the latch 23, which is left engaged with the bar 19. As the guide 43 is slided downward, the end portion 31 is engaged with a groove 51, and the engagement is released by the operation of the rod 29.

Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) The present invention provides a trunk space that connects a vehicle interior and a trunk room by moving a rear seat back forward from a seatable state with respect to a rear seat cushion. This invention relates to a rear seat that can be placed in a through state.

(Prior Art) Conventionally, a seatback lock device includes a seatback locking device having an operation lever for locking and unlocking the forward folding of a rear seatback, and a security locking device having a safety lever for locking and unlocking the seatback locking device. There is a rear seat.

In this case, the security lock device is provided to prevent belongings in the trunk from being stolen by a person other than the occupants by operating the control lever of the seatback lock device from inside the vehicle to enter the trunk through state. It is something.

(Problems to be Solved by the Invention) However, in conventional rear seats, both the seat back lock device and the security lock device have drawbacks such as a complicated structure, poor operability, and high cost. desired.

The present invention was made in response to such demands, and aims to provide a car seat equipped with a seat back lock device and a security lock device that have a simple structure, good operability, and are inexpensive. This is the purpose.

[Structure of the Invention (Means for Solving the Problems)] The present invention for achieving the above object includes a latch that is formed to be able to engage and disengage from a vehicle body side member and has a cam groove; The safety lever includes a rod whose lower end side engages with the cam groove of the latch and whose upper end side is attached to the operating lever, and a safety lever which has a guide inside the rod through which the rod is inserted. It is characterized by a structure in which the portion that is connected to the surface is formed on the tapered portion.

(Function) With the above configuration, when the safety lever is moved in the locking direction, the rod will be located in one corner of the cam groove of the latch due to the action of the guide and the tapered portion of the rod, and in this case, the operation Even if the lever is operated, the latch does not rotate and the engagement between the vehicle body side member and the latch is not released, so the seat back lock device is in a locked state.

Furthermore, when the safety lever is moved in the free (unlocked) direction, the rod is positioned at the engaging portion of the cam groove of the latch due to the action of the guide and the tapered portion of the rod. When the operating lever is operated, the latch rotates, the engagement between the vehicle body side member and the latch is released, and the seat pack locking device is brought into an unlocked state.

(Example) Hereinafter, an example of the present invention will be described based on FIGS. 1 to 10.

1 to 4, the rear seat 1 has a seat cushion 3, a seat back 5, and a headrest 7, and the seat back 5 is folded forward toward the seat cushion 3 as shown by an arrow 9 from a seatable state. It is possible. By folding the seat back 5 forward, the vehicle interior 11 and the trunk room 13 are communicated with each other, resulting in a trunk through state.

It should be noted that when the seat back 5 is folded forward, the headrest 7 is also rotated and stowed as shown by an arrow 15.

5 to 10, the frame 17 of the seat back 5 has a latch having an engagement recess 21 that can engage and disengage with a vehicle body side member such as a bar 19 that is integrally attached to the vehicle body. 23 is rotatably provided with the bin 25 as a fulcrum. A substantially heart-shaped cam groove 27 is formed in the latch 23, and the lower end side 31 of the rod 29 is engaged with the cam groove 27.

An operating lever 37 is attached to the upper end side 33 of the rod 29 and is rotatable about the bin 35 as a fulcrum. Further, the rod 29 has a tapered portion 39 that is slightly bent from the middle, and this tapered portion 39 is inserted through a guide 43 provided on the inner side of the safety lever 41.

Therefore, when the safety lever 41 is positioned on the lock side, the safety lever 41 rotates about the pin 45, and the guide 41 rotates as shown in FIGS. 5 and 6.
3 is located on the upper side. That is, the rod 29 moves to the left in the figure against the biasing force of the restring 44 due to the action of the tapered portion 39, and the lower end side 31 moves to the one corner 4 of the cam groove 27.
It will be located at 7.

In such a state, even if the operating lever 37 is rotated counterclockwise in the figure, the lower end side 31 of the rod 29 will move up and down somewhat along the inclined surface 49 of the cam WIt27. The latch 23 does not rotate and is in a locked state as a seat pack locking device.

As shown in FIGS. 7 and 8, the safety lever 4
1 to the free position, this safety lever 41
rotates about the bin 45 as a fulcrum, and the guide 43 is positioned on the lower side. Therefore, in the O-rad 29 inserted through the guide 43, the lower end side 31 moves to the right in the figure due to the action of the tapered portion 39 and the spring 44, and engages with the engaging portion 51 of the cam groove 27.

In such a state, if the operating lever 37 is rotated counterclockwise in the figure as shown in FIG. Rotate to. That is, latch 23
The engagement between the engagement recess 21 and the par 19 is released, and the seat back 5 can be folded forward. In this state, the seat back lock device is in an unlocked state.

As described above, in this embodiment, both the operating lever 37 of the seatback lock device and the safety lever 41 of the security lock device are connected to the rod 29, and the lower end side 31 of the rod 29 is connected to the cam of the latch 23. Since the rod 29 is engaged with the groove 27 and the rod 29 is provided with the tapered portion 39, the structure is extremely simple, the operability is good, and the cost can be reduced.

[Effects of the Invention] As described above, according to the present invention, there is provided a latch having a cam groove, a rod having a tapered portion whose lower end engages with the latch, and whose upper end is attached to the operating lever.
Since it is equipped with a safety lever that has a guide through which this rod is inserted, the structure is extremely simple, the number of parts can be reduced, and it is easy to assemble, and the operability is also extremely good and the cost is significantly reduced. The effects are significant, such as being able to reduce the amount of water used.
