Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an automobile seat, and more particularly to a seat that is arranged in front of a luggage compartment and whose seat back can be folded down onto a seat cushion. .

(Prior Art) In a type of automobile called a light van or wagon, the rear seats in front of the luggage compartment are generally designed so that the seat back can be folded down onto the seat cushion in order to ensure a wide cargo loading space. It is formed. In such cases, the above seat bag is used to make it easier to load luggage.
It is preferable that the back surface be formed at the same height as the floor surface of the luggage compartment when it is folded down.

However, as is well known, the floor directly below the seat cushion of the rear seat is relatively high due to the arrangement of the rear wheel axle, etc., and when the seat bag is folded down on the seat cushion, the back of the seat bag is on the cargo floor floor. It tends to be higher than the surface. Therefore, it has been considered to set the hinge position of the seat bag so that the seat bag is folded down as far forward as possible, but if this is done, the seat bag will be far away from the luggage compartment forward by a large distance, so the rear and the cargo compartment floor surface become discontinuous, and a recess is formed there. If such a recess is formed, even if the back of the seat back and the cargo compartment floor are at the same height,
It becomes difficult to load luggage.

Therefore, for example, as shown in Japanese Utility Model Application No. 57-39834, a cover plate is inserted between the back of the folded seat bag and the floor surface of the luggage compartment.
Attempts have also been made to make the floor surface for loading cargo completely flat. However, the provision of such a cover plate complicates the structure of the seat, causing problems such as making seat assembly troublesome.

(Objective of the Invention) Therefore, as mentioned above, even if the floor near the seat cushion is relatively high,
The object of the present invention is to provide an automobile seat that can form a completely flat cargo loading floor surface without using the cover plate.

(Structure of the Invention) As described above, the automobile seat of the present invention is an automobile seat in which the seat back can be folded down on the seat cushion, and the lower end of the seat back is rotatably supported. The hinge means allows the rear surface to be at approximately the same height as the floor surface of the luggage compartment when it is folded down, and is pivoted at a position where it can form a continuous floor surface with this floor surface. one end is pivotally mounted and the other end is pivotally mounted on the floor to enable the seat cushion to be moved from its use position to a storage position forward and below; This is equipped with a slider that slides in a guide groove provided on the side of the seat bag to guide the seat cushion from the use position to the storage position, and when the seat bag is laid down, the guide groove moves the slider forward. This feature is characterized in that the seat cushion is moved to the storage position by moving the seat cushion.

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

FIG. 1 shows an automobile seat according to an embodiment of the present invention, and FIGS. 2 and 3 show enlarged views of the main parts thereof. As shown in FIG. 1, a seat 10 serving as a rear seat of an automobile consists of a seat cushion 11 and a seat back 12, and a luggage compartment 13 is formed behind the seat 10. One end of a swing link 15 is pivotally connected to the lower part of the seat cushion 11 via a bracket 14, and the other end of the swing link 15 is connected to a bracket 1 fixedly mounted on a vehicle floor 16.
7 and is pivotably mounted to the shaft. On the other hand, at a position near the front end of the cargo compartment floor 18, the floor 16
A hinge bracket 19 is fixed to the seat, and the seat bag 12 is supported on the hinge bracket 19.

The structure around the hinge bracket 19 will be described below with reference to FIGS. 2 and 3. A hinge pin 20 is rotatably supported on the hinge bracket 19, and the seat bag 12 is fixed to the hinge pin 20, so that the seat bag 12 is fixed to the hinge bracket 19 (i.e., the seat back 12 is fixed to the hinge pin 20).
) can be rotated. A rotating plate 21 is integrally fixed to the hinge pin 20 and the seat back 12. A pin 22 is rotatably supported on the hinge bracket 19, and a lock release lever 23 is attached to the pin 22.
and the ratchet 24 are integrally fixed.
The lock release lever 23 and the ratchet 24 are connected to the pin 2 by a spring (not shown).
When the seat is in use, the lock release lever 23 comes into contact with a stopper 30 on the hinge bracket 19 and assumes the position shown in FIG. 2. Note that the rotating plate 21
The ratchets 24 and 24 are arranged at positions where their respective sides can abut against each other.

Further, a base end portion of a slider plate 25 is fixed to the rear portion of the seat cushion 11, and a pin 26 protruding toward the center of the seat is provided at the tip end of the slider plate 25. Note that the rotating plate 21 is arranged at a position where its side surface can come into contact with the side surface of the slider plate 25. Further, an elongated guide groove 27 extending in the longitudinal direction is formed in the side portion of the seat bag 12, and the pin 26 is slidably engaged in the guide groove 27.

Next, the operation of the seat 10 having the above configuration will be explained. When the seat is in use, the seat cushion 11 and the seat back 12 assume the positions indicated by solid lines in FIG.
At this time, the convex abutting part 25a of the slider plate 25 fixed to the seat cushion 11 enters into the concave abutting part 21a of the rotating plate 21, and the rotating plate 21 contacts the ratchet 24 from below. By being supported by the seat cushion 11, the seat cushion 11 is held in the above-mentioned use position. The pin 26 then engages with the lower end of the guide groove 27, thereby preventing the seat back 12 from rotating rearward. When the seat bag 12 is to be folded forward, that is, onto the seat cushion 11, the lock release lever 23 is first rotated forward (in the direction of arrow A in FIG. 2). As a result, the ratchet 24 is disengaged from the rotation plate 21, so that the seat bag 12 can be rotated around the hinge pin 20 and laid down as described above. Here, the hinge pin 20 is attached to the seat back 12 which is laid down.
The rear surface 12a of the vehicle is set at a position such that the rear surface 12a is approximately at the same height as the luggage compartment floor 18 and forms a continuous floor surface with the luggage compartment floor 18. If the luggage compartment floor 18 and the back surface 12a form a completely flat floor surface in this way, a large amount of luggage can be easily loaded on this floor surface.

When the seat bag 12 is laid down as described above, since the pin 26 is engaged in the guide groove 27, the slider plate 25 is pushed forward (at this time, the pin 26 slides in the guide groove 27). Therefore, the seat cushion 11 fixed to the slider plate 25 moves forward and downward while swinging the swing link 15, and when the seat back 12 is completely laid down, the seat cushion 11 is moved forward and downward as indicated by the two-dot chain line in FIG. Take position (storage position). As shown in FIGS. 1 and 2, the floor 16 is raised in the vicinity directly below the seat cushion 11 in the use position for the reason mentioned above.
1 is moved forward and downward, as described above, the seat back 12 can be laid down so that its back surface 12a is approximately at the same height as and continuous with the luggage compartment floor 18.

Furthermore, since the slider plate 25 is moved forward when the seat bag 12 is folded down, the distance L between the pin 26 and the hinge pin 20 (see FIG. 1) becomes longer. Since the luggage placed on the reclined seat bag 12 is supported via the pin 26 and the hinge pin 20, if the distance between them is increased as described above, the strength against the load of the luggage will be increased. It is advantageous in terms of
The tip side of 2 becomes difficult to sink due to the load of the baggage,
Loaded cargo becomes more stable.

In the embodiment described above, the pin 26 of the slider plate 25 is engaged with the guide groove 27 formed on the side surface of the seat bag 12, and the seat cushion 11 is moved forward and downward in conjunction with the lodging of the seat bag 12. However,
A guide groove is provided in a member fixed to the vehicle body separately from the seat back 12, and the seat cushion 11
The seat bag 12 may be moved forward and downward, and then the seat back 12 may be folded down by a separate operation.

(Effects of the Invention) As explained above in detail, according to the automobile seat of the present invention, even if the floor in the vicinity of the seat cushion is raised, the back surface of the reclined seat back and the floor surface of the luggage compartment can cover the entire surface of the seat. Since it is possible to form a flat cargo loading floor surface, it is possible to easily load a large amount of cargo.
Furthermore, the automobile seat of the present invention has a simple structure and is easy to assemble, since it does not use a cover plate or the like to cover the concave portion in order to form a completely flat cargo loading floor as described above. can also be easily done.

Furthermore, in the automobile seat of the present invention, when the seat bag is folded down, the guide groove provided on the side of the seat bag moves the slider forward, so that the seat bag rotates at its lower end. It is held by the hinge means which is pivotably supported and by the slider which has been moved further forward as described above. Therefore, when luggage is loaded onto the seat bag, the luggage is received by the hinge means and the slider, which are far apart from each other, which not only ensures high support rigidity for the luggage, but also stabilizes the luggage. It also gets better.
