Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a rear seat device for an automobile, and in particular, to an improvement in which the seat back serving as the backrest is foldable to ensure a wide storage space for luggage. .

(Prior Art) Conventionally, as a rear seat device for this type of automobile, as disclosed in Japanese Utility Model Application Publication No. 55-65222, a bending portion is provided at the upper end of the seat back of the rear seat by bending the upper end of the seat back rearward. It is known that when the seat bag is folded forward, the front end position of the luggage placed on the back side of the seat bag is regulated by the bent part, so that the bent part acts as a luggage load stopper. .

(Problem to be solved by the invention) By the way, in the above-mentioned rear seat device, when the seat bag serving as the back rest part is folded forward, the back contact surface of the seat bag overlaps the seating surface of the seat cushion serving as the seating part. In general, the back surface of the seat cushion is not positioned horizontally but is slightly inclined. Therefore, the bottom surface of the luggage storage space behind the rear seat and the back surface of the seat back are not integrally formed flat, and as a result, the cargo This may cause deformation, etc.

Therefore, in order to solve the above-mentioned problems, it is conceivable to provide a locking mechanism that maintains the seat bag in the forward-folded state, for example, so that when the seat bag is folded forward, the back surface of the seat bag becomes substantially horizontal. However, in this case, if a luggage stopper is rotatably provided separately at the upper end of the seatback and is raised when the seatback is folded forward, the luggage stopper will not be pulled up when the seatback is folded forward. , the locking mechanism also requires two operations,
Operability deteriorates.

The present invention has been developed in view of the above, and its purpose is to provide a reclining type rear seat in which the seat back can be folded forward, and to raise the rotatable luggage stopper when the seat back is folded forward. By performing the locking operation of the locking mechanism as described above in one operation, the object is to provide good operability and to secure a large baggage storage space so that the baggage does not fall apart.

(Means for Solving the Problems) In order to achieve the above object, in the present invention, when the luggage stopper is pulled up, the locking mechanism is automatically locked in conjunction with the lifting operation.

In other words, the specific solution of the present invention is that, in a reclining rear seat consisting of a seat cushion and a seat back, a luggage stopper is rotatably supported on the rear surface of the seat back, and a luggage stopper is rotatably supported on the side surface of the seat back. A lock mechanism is provided to maintain the seat back in the forward folded state. The lock mechanism is provided with a lock pin, the rear end of which is connected to the luggage stopper by a connecting member that can be tensioned and relaxed, and the lock pin is biased by a spring in the direction in which the hinge bracket of the seat bag is positioned. On the other hand, a lock groove is formed in the hinge bracket of the seat bag, into which the front end of the lock pin of the lock mechanism can fit when the seat bag is in the forward folded state. Furthermore, the above-mentioned Lagetsujistoppa,
When not in use, it is placed in a storage position where the connecting member is tensioned and the spring is contracted, and when in use, it is moved to a used position where the connecting member is relaxed.

(Function) With the above configuration, in the present invention, when the luggage stopper is not in use, it is positioned in the storage position. As a result, in the lock mechanism, the lock pin is pulled by the connecting member and retreats while contracting the spring, so that it does not fit into the lock groove of the hinge bracket and is in an unlocked state.

Now, in order to expand the luggage storage space, after folding the seat bag that serves as the backrest forward, and then raising the luggage stopper and positioning it in the use position, the connecting member is relaxed, and the locking pin of the locking mechanism is moved by the biasing force of the spring. It moves in the direction of the hinge bracket and fits into its locking groove to become locked.

Further, when returning the seat bag from the forward-folded state to the upright state, the luggage stopper is returned to the storage position. As a result, the connecting member is tensed in conjunction with this return operation, the lock pin moves back, and the engagement with the lock groove is released, resulting in an unlocked state and the seat back can be raised. Become. At this point, the luggage storage stopper is inevitably returned to the storage position, so even in the normal state with the seat bag upright, there is no protrusion in the luggage storage space behind the rear seat, and the space can be used effectively, resulting in good efficiency.

Moreover, it is highly practical because it can be constructed with substantially fewer members.

(Effect of the invention) As explained above, according to the automobile rear seat device of the invention, when the seatback of a reclining rear seat is folded forward, when the luggage stopper is pulled up, the locking mechanism is automatically locked at the same time, and the back of the seatback and luggage are automatically locked. Since the lower surface of the storage space is formed integrally and flatly, the locking operation of the locking mechanism is omitted, resulting in good operability and ensuring a wide luggage storage space to prevent cargo from collapsing. By always positioning the luggage storage stopper at the storage position, the luggage storage space behind the rear seat can be effectively utilized. Moreover, since it has a simple configuration, it is highly practical.

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings.

Figure 1 shows the rear seat section inside the vehicle. In the same figure, 1 is a floor panel, 2 is a floor panel 1
A reclining type rear seat is arranged above, and behind the rear seat 2 is a floor panel 1.
A baggage storage space 3 is formed using a flat portion 1a provided at the rear as a baggage placement surface. The rear seat 2 has a seat cushion 5 which serves as a seating part, and a backrest part whose lower end is attached to the vertical wall part 1b of the floor panel 1 via a hinge bracket 6 with two-stage bolts 7 so that it can be folded forward. The seat bag 8 is positioned at the normal position shown by the solid line in the figure when the luggage storage space 3 is empty with little luggage, while the seat bag 8 is positioned at the normal position shown by the solid line in the figure when the luggage storage space 3 is loaded with large luggage. As shown in the figure, the seat bag 8 is folded forward to form an auxiliary luggage storage space 3' above the seat bag 8, thereby ensuring a wide luggage storage space.

On the rear surface of the seat back 8 of the rear seat 2, a luggage stopper 9, which is manually operated by the operator at its upper end, is rotatably supported by a pin 11 via a bracket 10. The storage position shown by the solid line in the figure is stored along the rear surface of the seat bag 8, and the standing position shown by the imaginary line in the figure is that the seat bag 8 is rotated approximately 90 degrees counterclockwise from the storage position and stands on the rear surface of the seat bag 8. It can be selectively positioned in two positions.

Further, a lock mechanism 15 is provided on the left side surface of the seat back 8 of the rear seat 2 to maintain the seat back 8 in a forward-folded state. As shown in FIGS. 2 and 3, the lock mechanism 15 includes a lock pin 16 arranged parallel to the side surface of the seat frame 8a of the seat bag 8, and a component that supports the lock pin 16 so as to be movable from side to side in the drawings. It has a spring 19 which is compressed into the U-shaped member 17 and biases the lock pin 16 in the direction in which the hinge bracket 6 is positioned via the protruding pin 18 which is fitted into the lock pin 16. In addition, a lock groove 6a is formed in the hinge bracket 6 at a portion facing the lock pin 16 when the seat bag 8 is tilted forward and the lock pin 16 is in a horizontal state. has been done. Therefore, in the lock mechanism 15, when the seat back 8 is folded forward, the lock pin 16 is urged in the side direction of the hinge bracket 6 by the urging force of the spring 19, and its tip end is inserted into and engaged with the lock groove 6a of the hinge bracket 6. By doing so, the seat bag 8 is maintained in the forward tilted state so that the rear surface of the seat bag 8 becomes horizontal.

As shown in FIG. 1, the rear end of the lock pin 16 of the lock mechanism 15 is connected to the bracket 10 of the luggage stopper 9 by a connecting member 20 made of a wire or the like that can be tensioned and relaxed. As shown in FIG. 1, when the luggage stopper 9 is not in use and is positioned in the storage position, the mechanism 15 tensions the connecting member 20 by the luggage stopper 9, and the lock pin 16 is pulled upward by the connecting member 20. The spring 19 of the locking mechanism 15 is contracted against the urging force of the spring 19 of the locking mechanism 15, and retreats upward, and is positioned at the unlocked position where the tip of the spring 19 has slipped out of the locking groove 6a of the hinge bracket 6, while the luggage stopper When 9 is raised to the standing position as its use position,
Seat back 8 as shown in Figures 2 and 3.
When folding forward, the connecting member 20 is loosened by the luggage stopper 9, and the lock pin 1 is thereby loosened.
6 is moved to the right in the figure by the biasing force of the spring 19 and positioned at a locking position where it is inserted into and engaged with the locking groove 6a of the hinge bracket 6. Therefore, the lock mechanism 15 is configured such that when the luggage stopper 9 is raised from the storage position to the upright position, the lock pin 16 is positioned at the lock position and locked. Next, the operation of the above embodiment will be explained.
First, when the vehicle is empty and there is little luggage in the luggage storage space 3, the seat back 8 of the rear seat 2 is in the normal upright position, and the luggage stopper 9 is located in the storage position. Therefore, the connecting member 20 is pulled upward, and the locking pin 16 of the locking mechanism 15 is pulled upward.
is located in the unlocked position.

When a large piece of luggage is to be stored in the baggage storage space 3, the seat back 8 of the rear seat 2 is first folded forward to form an auxiliary baggage storage space 3' above the seat bag 8, and at the same time, the front end position of the baggage is adjusted. The luggage stopper 9 is raised from the stowed position to the upright position in order to regulate the load. At this time, as the luggage stopper 9 is pulled up, the connecting member 20 is relaxed, and the locking mechanism 15 locks its locking pin 16.
is positioned at the lock position and locked. As a result, the back surface of the seat bag 8 is held horizontally, and the lower surface of the luggage storage space 3 (the flat portion 1a of the floor 1) and the lower surface of the auxiliary luggage storage space 3' are integrally formed flat. Become. Therefore, when the seat back 8 is folded forward, the luggage load stopper 9 must be pulled up.
Since the lower surfaces of the baggage storage spaces 3, 3' can be formed integrally and flat by locking the locking mechanism with only one operation, the baggage storage space can be secured wide and with good operability to prevent loads from collapsing.

Furthermore, when the seat bag 8 is pulled back from the forward-folded state to the normal position, the luggage stopper 9 is returned to the stowed position. As a result, the connecting member 20 becomes tense and the locking pin 16 retreats upward.
Since the engagement with the lock groove 6a is released, the seat back 9 becomes unlocked and can be pulled up. Here, when the seat back 8 is pulled back to the normal position, the luggage stopper 9 is always returned to the storage position, so when the seat back 8 is in the upright normal position, the luggage stopper 9 does not protrude into the luggage storage space 3 behind the rear seat 2. There is no protrusion, and the baggage storage space 3 can be used effectively, which is efficient.

Moreover, the luggage stopper 9 and the lock mechanism 15
Since the connecting member 20 can be used to connect the connecting member 20, the configuration can be made by substantially adding only a small number of members, and it can be highly practical.
