Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a reclining rear seat device for a vehicle in which the seat back can be raised and folded.

(Prior Art) Van-type vehicles have been put into practical use with separate rear seats and independent reclining mechanisms that allow the left and right rear seat backs to be reclined individually as desired.

By the way, one of the rear seatbacks is folded back and a long item is loaded onto the rear cargo platform, the fallen seatback, and the seat cushion. A rear seat passenger may occupy the seat.

(Problem to be solved by the invention) In the case of the above-mentioned separate type reclining rear seats, the seat backs of either the left or right seats can be moved backwards independently, so for example, if the left seat back is moved backwards. When luggage is loaded on the seat, the passenger will board the right seat. By the way, in our country, vehicles are required to drive on the left side by law, and if the left seat is loaded with luggage, the left side is blocked, so you have no choice but to get on and off from the right side, and vehicles cannot pass on the right side. Because of this, boarding and alighting from this side is not recommended.

The present invention was made to solve the above problems, and its purpose is to enable the right rear seat of the vehicle to be independently folded back, and only when the left seat is connected to the right seat. Adjustment in the reclining direction or rearward is possible, and when loading luggage, only the right seat is tilted backwards and luggage can be loaded on this side.
To provide a rear seat device for a vehicle that allows an occupant to board only the left seat and allows the occupant to get on and off only from the left side door of the vehicle.

(Means for Solving the Problems) In order to solve the above problems, the present invention has been developed to prevent the tilting of the right seat seat back from the left and right seat backs that are provided in the rear seat of a vehicle so as to be tiltable. A first regulating means for regulating the tilting of the seat back of the left seat, a second regulating means and a third regulating means for doubly regulating the tilting of the seat back of the left seat, and a linking means for linking the left and right seat backs, The right seat back can be tilted independently by a release operation on the restriction means, and the second restriction means is released by connecting the left and right seat backs by the connection means, and the second restriction means is released. By performing a release operation on the first and third regulating means, the left and right seat backs are connected and can be tilted as a unit.

(Operation by the above means) According to the above means, the right seat back can be tilted independently, so that cargo can be loaded by tilting it, while the left seat back has a double restriction means. The left seat back cannot be tilted by releasing only one of them, and the other can only be released when the right seat back is in an upright position, so the left seat back can only be tilted at the same time as the right seat back, and the rear seats cannot be tilted. Tilt one side of the bag and load the baggage.
When boarding the other vehicle, only the right seat back can be tilted independently, so the left seat can be used, and therefore the vehicle must be entered and exited through the left door.

(Embodiment) Next, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

It consists of seat backs 502, 602 which are erected on the rear end of the seat back 601 so that they can be tilted back freely. right seat 6
Fix the lower part of the L-shaped bracket 603 to the rear side of the seat cushion 601, and then
The upright part 604 faces the side surface of the seat bag 602, and the upright part 604 and the seat back 602 are pivotally connected with a pin 605 so that they can be raised and folded. A holding mechanism (first regulating means), not shown, is provided at the pivot portion to restrict the falling motion and maintain the seat bag 602 in the upright state. Pull the control cable shown to release the retention mechanism and pin 6.
The seat bag 602 is tilted backwards using 05 as a fulcrum.

On the left side of the rear end of the seat cushion 501 of the left seat 5 is a bracket 7 made of an L-shaped plate.
The lower end of the side surface of the seat bag 502 on this side is pivotally attached to the upright piece 701 via the pin 8 by the upright piece 701 of the bracket 7, whereby the seat bag 502 can be tilted backwards using the pin 8 as a fulcrum. For such pivoting, a plate-shaped bracket 9 is attached and fixed to the lower side of the seat bag 502,
The pin 8 passes through the upright piece 701 of the bracket 7 and the lower part of the bracket 9.

At the middle lower part of the bracket 9, a rearward tilting lock plate 10, which is approximately Z-shaped in side view, is pivotally attached by a pin 11. Engages with a locking recess 702 provided on the upper edge of the piece 701,
The distal end is pivotally connected by a pin 11, and the distal end is provided with a claw portion 102 that projects upward, and furthermore, a horizontal piece portion 103 that extends back and forth is provided with an upward protruding portion 104 at the intermediate portion thereof. A release link 12 and a stopper 13 are arranged above the lock plate 10, and the stopper 1
3 is a hanging stopper part 1 which is approximately L-shaped in side view.
31 faces the rear upper edge of the protrusion 104 of the lock plate 10 and prevents the lock plate from swinging in the disengagement direction. On the other hand, the link 12 has a V-shape in side view, and one side is used as a release claw part 121, and it faces close to the rear of the catch part 102 of the lock plate 10.
The link 12 and the stopper 13 are commonly pivotally connected by a pin 14, the other protruding piece 122 of the link 12 is connected to the lower end of the rod 15, and the upper end of the rod 15 is arranged at the corner of the upper end surface of the seat bag 502. The pull knob 16 is connected to the pull knob 16.

An arm 132 extending rearward of the stopper 13 is connected to the tip of an inner 171 of the operating cable 17, and the cable 17 is routed inside the seat bag 502 to a release link 18 provided at the middle of the rear right end of the seat bag 502 in the height direction. Connect to. This is shown in FIG. 4, in which a substantially Y-shaped link 18 is pivotally attached to the board 19 with a pin 20, and one arm 181 of the link 18 diagonally upward is connected to the inner 171 of the cable 17.
is connected to the starting end of the arm 182, and an engagement step 182 is provided at the bottom, and another arm 183 is connected to the other arm diagonally upward.
is provided with a knob 184 that protrudes toward the front. A cam guide 21 is pivotally mounted 212 under the link 18.
However, the cam guide 21 is provided with a cam groove 211 on the front side, and in FIG. Addendum. A cover plate 22 is fixed to the outer surface of the base plate 19 to expose the cover plate 22 on the back surface of the seat back, and a hole 2 larger than the cam groove 211 of the cam guide 21 is formed in the lower part of the cover plate 22.
21, and a long hole 2 from which a knob 184 protrudes from the top.
22 is provided.

On the other hand, one end of a strap 23 is tied to the rear left side of the right seat bag 602, and a release cam 24 is rotatably connected to the tip of the strap 23, and the cam 24 is engaged with the cam groove 211. It consists of a cam portion 241 and a knob 242.

In the above, FIGS. 2, 3, and 4 all show the locked state in which the rearward tilting of the seat back 502 of the left seat 5 is restricted, and the lock mechanism has a second lock that restricts the release rocking of the lock plate 10. It is comprised of a stopper 13 as a first regulating means and a release link 12 as a third regulating means, and is doubly locked. Therefore, the seat back 50 of the left seat 5
2 does not fall down either front or back.

On the other hand, the seat bag 602 of the right seat 6 falls down by pulling the pull knob 606, and
The figure shows this, where only the right seat bag 602 falls down, the left seat bag 502 maintains an upright state, the right side falls down to allow loading of luggage, and the left seat bag 502 stands up to accommodate the passenger. Therefore, the occupant has no choice but to sit on the left seat 5, and is forced to get in and out of the vehicle only through the rear left door. By the way, suppose that the pull knob 16 is pulled in an attempt to fold down the left seat bag 502. As a result, the link 12 swings clockwise in FIG. 3 via the rod 15, swings the release claw portion 121 in the same direction, and engages with the receiving claw portion 102 of the lock plate 10, thereby locking the plate 10. Although the lock plate 10 attempts to swing counterclockwise using the pin 11 as a fulcrum, the stopper portion 131 of the stopper 13 comes into contact with the rear upper edge of the protrusion 104, preventing the lock plate 10 from swinging. Therefore, the upright state of the seat bag is maintained and the lock is not released.

In this way, the seat back 602 of the right seat 6 can be moved backwards freely and independently, while the left seat 5
The seatback 502 cannot be independently folded backwards, and by folding the seatback backwards, cargo can only be loaded on the right seat, forcing the passenger to sit on the left seat.

By the way, the left seat back 502 can be moved backwards under the following conditions.

That is, the user grasps the knob 242 connected to the strap 23 of the right seat bag 602 in the upright position, inserts the cam portion 241 into the hole 221 on the back surface of the left seat bag 502, and engages the cam portion 241 with the cam groove 211 inside. Then, the knob 242 is rotated clockwise, so that the cam guide 21 swings in the same direction, and the link 18 that engages with this swings counterclockwise using the pin 20 as a fulcrum. engages with the stepped portion 182 to maintain the swing of the link 18 at a predetermined angle. This is shown in FIG.
Due to the swinging of the link 18, the cable inner 171
is pulled down, and the stopper 13 connected to the end thereof is swung counterclockwise in FIG. 3 about the pin 14, and the stopper portion 131 is separated from the lock plate 10. This means that the second restricting means 13 is released. Next, pull knob 16
When the link 12 is pulled, the link 12 swings clockwise about the pin 14 via the rod 15, and the claw portion 10
2 is pressed by the claw portion 121, the lock plate 10 is swung counterclockwise about the pin 11, and the locking claw portion 101 is released from the locking recess 702. This means that the third restricting means 12 is also released. Here, since it is necessary to release the first restricting means in order to tilt the right seat back, by simultaneously performing the releasing operation for the first restricting means (pulling the pull knob 606), the left and right seat backs can be tilted. Both seat backs are in a tiltable state, and as shown in FIG. 7, the left and right seat backs 502,
602 is moved backwards at the same time, making it possible to load cargo onto seats 5 and 6.

Since the seat bag 502 is unlocked, the seat back 502 is raised manually, and when the knob 184 protruding from the elongated hole 222 is pressed to the right after being raised, the stepped portion 182 is raised.
The engagement of the tip of the cam guide 21 is released, and the lock plate 10, link 12,
Stopper 13 is restored to its original state, and link 18 is connected with a cable.
is pulled back to the state shown in Figure 4 and locked.

Although the embodiments have been described in detail above, the restricting means and the method for canceling the restricting means are not limited to those shown in the drawings and may be arbitrary.

(Effects of the invention) As is clear from the above, according to the invention, the right seat back can be tilted independently, so that luggage can be loaded by tilting it, while the left seat back is double installed. It is not possible to tilt the vehicle by simply releasing one of the restricting means, and therefore, it is impossible to tilt the vehicle with the right seat back upright.If there is one passenger in the rear seat, the vehicle must be seated in the left seat. I don't get it. Therefore, passengers can only get on and off the vehicle through the door on the left side, which is opposite to the traffic side of the vehicle. By linking the left seat back with the right seat back and releasing one of the restricting means, and further releasing the other restricting means, the double restriction is released, and the right seat back is simultaneously released. By performing the tilting operation, the left and right seat bags can be tilted together, and when loading large items, the left and right seats can be tilted, which is convenient for loading.
