Description

FOLDING LEVER INDICATING DEVICE FOR SEAT BACK OF VEHICLE}

The present invention relates to an apparatus for indicating a folding lever for a seatback for a vehicle, and more particularly, a folding lever for an automobile seatback of a film type that allows easy confirmation of whether the seatback is folded or locked at an unfolded position. It relates to a catering device.

In general, a seatback folding device for folding a seatback onto a surface of a seat cushion is applied to a second or third row seat of a vehicle in order to secure a wider luggage space or to secure a passage to a rear seat.

1 and 2, a folding lever 20 for folding the seatback 10 is mounted at a predetermined position at the upper end of the second row seatback 10 so as to be able to fold, and the rear portion of the seatback A latch assembly (not shown) that is interlocked with the lever and the wiring is mounted.

Accordingly, when the seatback 10 is erected (unfolded), the latch assembly mounted on the rear surface of the seatback is locked and locked with the striker mounted at a predetermined position on the vehicle body, so that the seatback 10 does not move in the erected state. It can be in a fixed state.

On the other hand, if the seatback 10 is to be folded over the seat cushion while the seatback 10 is erected, when the folding lever 20 is tilted upward and pulled, the wiring connected to the folding lever 20 is pulled, and at the same time, a latch detachable from the striker. As the assembly is unlocked, the seat back 10 is pushed onto the seat cushion to be folded.

Again, when the user switches the seatback from the folded state to the unfolded state (the seatback is upright), that is, when the seatback is pushed in the unfolding direction to change it to the upright state, the latch assembly mounted on the seatback The seatback can be securely fixed in an upright state only when it is locked and locked to the striker mounted in a predetermined position. In addition, when the locking operation of the latch assembly, the wiring is pulled in the opposite direction, and the folding lever 20 rotates to its original position before folding. It can be arranged in a flat state.

At this time, a marking portion 22 (eg, red color) indicating an unlocking state is engraved on the side of the folding lever 20.

Therefore, when the folding lever 20 is tilted upward for folding of the seatback as described above, the marking part 22 engraved on the side of the folding lever 20 is exposed to the outside, so that the user can use the marking part 22 Is in a state where you can visually check.

Accordingly, when the seatback is converted from the unfolded state (the seatback is erected) to the folded state, or when the folded state is returned to the unfolded state, the latch assembly is unlocked (the seatback is folded or unfolded). In the unlocked state that can be moved in the direction), the folding lever 20 is arranged in an upwardly tilted state, so that the user sees the marking portion 22 engraved on the side of the folding lever 20 and the current seatback is folded. It can be seen that it is in a possible unlocked state.

For example, when the passenger pushes the seatback from the folded state to the unfolding direction to change it to the upright state, even if the latch assembly cannot be pushed until the striker is locked, the passenger may Looking at the marking portion 22 engraved on the latch assembly, it can be confirmed that the latch assembly is still in an unlocked state (the seatback is in an unlocked state that can move in the folding and unfolding directions). You can induce pushing the seatback further in the unfolding direction.

However, since the marking part 22 is engraved on the side of the folding lever 20, there is a problem in that it is difficult to see when the passengers in the driver's seat and the passenger seat of the first row of seats see it, and thus visibility is poor.

For example, when a passenger pushes the seatback from the folded state in the unfolding direction to change it to the upright state, if the latch assembly is seated in the driver's seat or the passenger seat of the first row of seats without pushing until the latch assembly is locked to the striker. , Since the marking part 22 is engraved on the side of the folding lever 20, passengers in the driver's seat and the passenger seat cannot see the marking part 22 well.

Thus, although the seatback has been moved from the folded position to the unfolded position, the vehicle may be driven in a state in which the latch assembly is not locked to the striker, and in situations such as braking or sudden acceleration while the vehicle is driving. An impact may occur in which the seatback is rapidly folded over the seat cushion, and accordingly, there is a problem that may cause damage to the internal parts of the seatback and a safety accident.

Therefore, the first color section 401 of the film 400 wound around the film roll 300 at the original position before the folding lever 200 is folded is exposed to the outside through the locking hole 201, Alternatively, when rotating according to the folding operation of the folding lever 200, the film 400 is further extracted from the film roll 300 so that the second color section 402 is exposed to the outside through the locking hole 201. I can.

Preferably, the first color section 401 of the film 400 is applied in a green color to indicate that the seatback is in a locked state (locked state of the latch assembly) through the locking hole 201 and exposed to the outside. Can be.

On the other hand, the second color section 402 of the film 400 is applied in red, indicating that the seatback is unlocked (the latch assembly is unlocked) through the locking hole 201 and exposed to the outside. Can be.

Here, an operating state of the folding lever indicating device of the present invention having the above-described configuration is as follows.

First, when the seatback is erected (unfolded), the latch assembly mounted on the back of the seatback is locked and locked with the striker mounted at a predetermined position on the vehicle body, so that the seatback can be in a state of being fixed so that it does not move in the erect state. have.

At this time, the folding lever 200 is also in its original position before being folded, and the first color section 401 of the film 400 wound around the film roll 300 is passed through the locking hole 201. It is exposed to the outside.

For example, the green color applied to the first color section 401 of the film 400 indicates that the seatback is locked (the latch assembly is locked) through the locking hole 201 of the folding lever 200. Directed and exposed to the outside.

Accordingly, when the driver seated in the first row seat and the passenger in the passenger seat look back, the first color section 401 of the film 400 exposed through the locking hole 201 of the folding lever 200 Since the green color can be easily seen, the passenger can easily visually recognize that the seatback is in the locked state (the latch assembly is in the locked state).

On the other hand, in the case of folding over the seat cushion while the seat back is upright, when the folding operation plate 210 of the folding lever 200 is pulled upward and the folding operation is performed, the hinge fastening end 231 of the rotating body 230 The entire folding lever 200 rotates forward angularly, and the wiring connected to the wiring connection end 232 of the folding lever 200 is subsequently pulled, and latched by the pulling force of the wiring. The assembly is operated to unlock the striker and detachable, so that the seatback can be pushed over the seat cushion to fold.

At this time, when the folding lever 200 rotates according to the folding operation, the length of the film 400 pulled out while being released from the film roll 300 is increased, so that the second color section 402 of the film 400 is It is exposed to the outside through the locking hole 201.

That is, when the folding lever 200 is tilted while the other end of the film 400 is fixed to the rear surface of the lower opening 102 of the folding lever housing 100, the film roll 300 is stored As the position of the film roll storage space 212 of the lever 200 is raised to the front and the position is moved, the film 400 has to be further extracted from the film roll 300, and accordingly, the second color of the film 400 The section 402 is exposed to the outside through the locking hole 201.

For example, the red color applied to the second color section 402 of the film 400 is in the unlocking state of the seatback through the locking hole 201 of the folding lever 200 (the unlocking state of the latch assembly) ) And is exposed to the outside.

Accordingly, when the driver seated in the first row seat and the passenger in the passenger seat look back, the second color section 401 of the film 400 exposed through the locking hole 201 of the folding lever 200 Since the red color can be easily seen, the passenger can easily visually recognize that the seatback is unlocked (the latch assembly is unlocked).

In other words, when the seatback is in a folded state or when the seatback is returned to the unfolded state, the latch assembly is in an unlocked state (the seatback is in a unlocked state in which the seatback can move in the folding or unfolding direction), the folding lever 200 ), which is the second color section 401 of the film 400 exposed through the locking hole 201, the passenger can easily see the red color from any position, so that the passenger can unlock the seatback ( It is easy to visually recognize that the latch assembly is unlocked).

Therefore, when the passenger pushes the seatback from the folded state in the unfolding direction to change it to the upright state, even if the latch assembly cannot be pushed until it is locked to the striker, whether the passenger locks the folding lever 200 Looking at the red color, which is the second color section 401 of the film 400 exposed through the confirmation hole 201, the latch assembly is still unlocked (the seatback is in an unlocked state in which the seatback can move in the folding and unfolding directions) It can be confirmed that, and thus, it is possible to easily induce the passenger to further push the seatback in the unfolding direction until the latch assembly is locked to the striker.

As seen above, the passenger can visually and easily check the locking state or unlocking state of the seatback while viewing the color of the film 400 exposed through the locking hole 201 of the folding lever 200 in any direction. Therefore, it is possible to induce a locking operation in the unfolding state of the seatback that has not been locked to the passenger, and accordingly, the vehicle is driven in a state in which the seatback is erected but unlocked (the latch assembly is not locked to the striker). You can prevent this from happening.
