BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described.
FIG. 1 is a perspective view of a vehicle rear seat capable of creating a storage space for luggage. FIG. 2 is a perspective view showing a state in which the constituent members on the seat cushion side are disassembled. FIG. 3 is a sectional view showing the internal structure of the seat cushion similarly.
[0010]
The seats shown in these drawings are for two or three people, and are constituted by a seat cushion 10 and a seat back 40. The seat cushion 10 is configured to be separated into a base portion 12 and a cushion portion 20. The base portion 12 has a shape in which side portions 12a forming both sides of the seat cushion 10 and a rear portion 12b forming the rear side are connected in a U-shape in plan view. In a region surrounded by the base portion 12, the upper and lower surfaces and the front surface are open.
And the cushion part 20 is located in this area.
[0011]
The cushion part 20 is divided into two parts in the width direction of the seat cushion 10. These two cushion portions 20 can be individually rotated from a seatable state shown by a solid line in FIG. 3 to an upright state shown by a virtual line. In FIG. 1, the left side of the vehicle in both cushion portions 20 is shown in a seatable state, and the right side is shown in an upright state. When the cushion portion 20 is in a seatable state, the upper surface of the base portion 12 and the upper surface of the cushion portion 20 are set to be substantially flush with each other. Thereby, the upper surface of the base portion 12 and the upper surfaces of both cushion portions 20 serve as a series of seating surfaces, and maintain properness as the seat cushion 10. The seat back 40 is also divided into two parts in the width direction of the seat cushion 10. The division line of the seat back 40 is made to correspond to the same line as the division line of the cushion portion 20.
[0012]
In the seat cushion 10, a tray 14 is provided on a bottom surface of a region surrounded by the base portion 12. This tray 14 is also divided so as to correspond to both cushion portions 20 (FIG. 2). However, the division of the tray 14 is mainly due to a design factor, and may be functionally integrated. On the lower surface on the front side of the tray 14, a tray frame 16 that is continuous over the entire width of the tray 14 is disposed. The front side edge of the tray 14 is connected to the upper surface of the tray frame 16. The tray frame 16 is fixed to the vehicle body 50 shown in FIG. 4 through stays 16a provided at a plurality of positions (two positions) in the length direction.
[0013]
FIG. 4 is an enlarged sectional view of a part of FIG. As is clear from this drawing, a hinge bracket 24 is fixed to the upper surface of the tray frame 16 by a bolt 26. A total of four hinge brackets 24 are provided on both sides of both cushion portions 20. On the other hand, hinge plates 28 fixed to the internal frame 22 are provided on both sides of each cushion portion 20, respectively. In each of the cushion portions 20, the hinge brackets 24 and the hinge plates 28 on both sides thereof are rotatably connected by one rotation shaft 30 penetrating therethrough.
[0014]
With this configuration, both cushion portions 20 can rotate from the seatable state to the upright state with the respective rotation shafts 30 as fulcrums, as described above. A torsion coil spring 32 is provided on the rotation shaft 30. The elastic force of the spring 32 acts to assist the cushion portion 20 in turning to the upright state. The upright state of the cushion portion 20 is regulated by a stopper (not shown) provided between the hinge bracket 24 and the hinge plate 28. The front side of the tray frame 16 is covered with a protector 17.
[0015]
In both cushion portions 20, the hinge plates 28 located on the respective outside sides each have a lock mechanism 34. The lock mechanism 34 holds both the cushion portions 20 in a seatable state, and can release these locks individually. The lock mechanism 34 includes a release lever 34a and a lock arm 34b. The release lever 34a and the lock arm 34b are rotatably supported on the hinge plate 28 by individual shafts 34a-1 and 34b-1.
[0016]
A pin 34a-2 provided at one end of the release lever 34a is engaged with a hole of the lock arm 34b, so that the release lever 34a and the lock arm 34b are interlocked. A spring 34c having elasticity in the pulling direction is hooked between the release lever 34a and the lock arm 34b. An operation member 36 using a strap is connected to a connection fitting 34a-3 rotatably connected to the other end of the release lever 34a. The operating member 36 is located in a state of being drawn upward from between the side portion 12 a of the base portion 12 and the cushion portion 20.
[0017]
3 and 4 show a locked state of the lock mechanism 34. In this state, the distal end of the lock arm 34b is engaged with a member (not shown) on the fixed side (the hinge bracket 24 side). To release the lock of the lock mechanism 34, the operating member 36 is pulled upward, so that the release lever 34a rotates counterclockwise around the shaft 34a-1. In conjunction with this, the lock arm 34b rotates clockwise around the shaft 34b-1, and the distal end of the lock arm 34b is disengaged from the fixed member to release the lock.
[0018]
When it is desired to create a storage space for luggage in the seat cushion 10 in the seat configured as described above, one or both of the operating members 36 of the both cushion portions 20 are pulled upward. Thereby, the lock of the lock mechanism 34 is released as described above. Therefore, by pulling the operation member 36 as it is, the cushion portion 20 rotates in a manner of jumping up while receiving the assisting force of the spring 32, and changes from the seatable state to the standing state. Then, the tray 14 appears on the trace of the cushion portion 20 that has been erected, and the periphery thereof is a storage space surrounded by the base portion 12 and the cushion portion 20 that is in the upright state.
[0019]
Luggage placed on the tray 14 in the storage space is prevented from slipping even when the vehicle turns, for example, by a wall formed by the surrounding base portion 12 and the cushion portion 20, and is prevented from jumping out of the storage space. In addition, the seat back 40 corresponding to the upright cushion portion 20 is tilted forward, so that the seat back 40 is positioned on the upper surface of the storage space. In other words, the folded back of the seat back 40 is received on the upper surface of the side portion 12a of the base portion 12, and the upper surface of the storage space is closed. This prevents the luggage from jumping out of the upper opening of the storage space.
[0020]
If both cushion portions 20 are in the upright state, large luggage can be placed in the created storage space. Further, even when only one of the cushion portions 20 is used as a storage space by standing up, the other cushion portion 20 can be used for seating of a person. The storage space does not need to provide a special space below the seat cushion 10, and the thickness of the seat cushion 10 (cushion portion 20) is effectively utilized.
[0021]
When the cushion portion 20 in the upright state is pushed back against the elasticity of the spring 32, the cushion portion 20 rotates to a seatable state. Then, the lock mechanism 34 is locked, and the cushion portion 20 is held in a seatable state. When the cushion portion 20 is in a seatable state, the operation member 36 of the lock mechanism 34 is located at a boundary between the side portion 12 a of the base portion 12 and the cushion portion 20. Thereby, as the seat cushion 10, there is no foreign body feeling below the buttocks of the seated person, and good sitting comfort can be maintained.
[0022]
Although the preferred embodiment of the present invention has been described with reference to the drawings, this embodiment can be easily modified or modified without departing from the spirit of the present invention.
For example, in the drawings, a rear seat for two or three people is intended, but the invention is not limited to this. Further, the present invention can be applied to a separate type sheet. Further, the spring 32 for assisting the rotation of the cushion portion 20 can be replaced with a spiral spring or a torsion bar type spring. The lock mechanism 34 and the operation member 36 can also be changed to other types.
