Description

[Detailed Description of the Invention] << Industrial Application Field >> The present invention relates to a rear seat for an automobile, and more particularly to a rear seat used for a so-called trunk through type in which a trunk room and a passenger compartment are communicated by tilting the rear seat. .

<Prior art> In this type of trunk-through type, the body panel on the back of the seat back of the rear seat has a large opening,
The trunk room and the vehicle compartment are communicated with each other through the opening so that even long articles can be stored and a narrow luggage space can be effectively used.

When storing luggage, the seat back is unlocked from the vehicle body panel, and a forward leaning operation is performed to form a luggage compartment space, which is accommodated from a trunk room or the like.

<Problems to be solved by the invention> However, in the case of the conventional retractable rear seat, the gap between the front seat and the rear seat is narrow, so when the seat back is tilted forward, the seat back on the front side falls down. There were times when it couldn't be cut, and it was necessary to slide the front seat to the foremost position in order to surely tilt it into a flat shape.

In addition, for example, when a long ski is supported in the trunk through state, the ski slides due to inertia during a sudden stop or collision and easily hits the back surface of the front seat back and damages the back surface.

In order to eliminate this problem, there is a rear seat provided with a luggage stopper on the back surface of the seat back so as to prevent the luggage from jumping forward. However, if a separate luggage stopper is to be provided, a mounting bracket or the like must be used, and if the luggage stopper is provided tiltably, the structure becomes complicated,
There is also the problem of high costs.

Further, conventionally, for example, as disclosed in Japanese Utility Model Laid-Open No. 59-106455, there has been proposed one in which a head dress is rotatably mounted on the seat bag and the head dress is used as a stopper for luggage. Since the height of the seat is integrated, its height does not change even if the headrest rotates.Therefore, when the clearance between the front seat and the rear seat is small, the front seat can be tilted forward when the seat back is tilted. It may not fall down by hitting the seat back on the seat side, and the front seat must be slid to the front row in order to surely tilt it into a flat shape. Further, in this technique, in addition to the locking device for locking the seat back onto the vehicle body, since the locking device for the seat back is provided for the seat back, two locking devices are provided before the seat back is tilted forward to form a flat shape. There is a problem that it has to be removed and is troublesome.

In consideration of the narrow gap between the front seat and the rear seat, the present invention prevents the seat back of the rear seat from hitting the front seat back and falling over when the seat back of the rear seat is operated forward. An object of the present invention is to provide a rear seat for an automobile that does not require a troublesome operation of tilting in a flat shape after sliding up to.

<< Means for Solving the Problems >> That is, the present invention is a retractable rear seat used for a trunk-through type, wherein the seat back of the rear seat is divided into at least a lower back body and an upper back portion. The lower back main body is supported so that it can be tilted forward with respect to the vehicle body panel, and the main frame of the upper back portion is rotatably attached to the lower back main body bracket so as to be rotatable. The upper back portion is joined to the lower back main body in such a manner that the upper back portion is rotated within the range of about 90 ° and the seat back is tilted forward to the lower back main body. On the other hand, a stopper is provided so that the upper back part stands upright, and is attached to the lower back body on the vehicle body panel side so that the lower back body stands up. The striker that engages the latch of the locking device for holding configured by projecting.

<< Operation >> According to this configuration, the seat back of the rear seat can be surely tilted forward regardless of the front-back position of the front seat.
In addition, the upper back portion can function as a luggage stopper when it is tilted forward.

<< Embodiment >> An embodiment of the present invention will be described in detail below with reference to FIGS.

FIG. 1 is a schematic view showing a state in which a rear seat to which the present invention is applied is arranged in a vehicle compartment.

In the figure, a slidable front seat 2 and a retractable rear seat 4 arranged in parallel with the front seat 2 with a constant gap therebetween are arranged in a vehicle interior 1.

The vehicle body panel 8 extending to the back surface of the rear seat 4 is largely opened at the back of the rear seat 4, and the trunk room 9 and the room 1 are communicated with each other through the opening 8a so that even luggage such as long articles can be stored. It is becoming like this.

As shown in FIG. 2, the rear seat 4 includes a seat cushion 6 fixed on a vehicle body panel 8 and a locking device 11 mounted on the vehicle body panel 8 from the trunk room 9 side.
The seat back 5 is locked by means of the seat back 5, and side supports 7 that form both side portions of the seat back 5 and are fixed to the vehicle body panel 8.

The seat back 5 is a joint pin 10 fixed to both side supports 7 through a bracket 7a (see FIG. 4).
The seat back 5
The striker 54 protruding from the back surface of the vehicle body is penetrated through the through hole 8b provided in the vehicle body panel 8 and is locked by the locking device 11 to maintain the standing state. Also seat back 5
Is supported by a bracket 5a (see FIG. 4) that bears the joint pin 10, and the bracket 5a is provided with a spring member (not shown) that constantly urges the seat back 5 in a direction to incline forward. Therefore, seat back 5
Is automatically tilted forward by the spring member in the unlocked state.

As shown in FIG. 3, the locking device 11 is located inside the housing 12, and has a latch 13 corresponding to the striker 54 and a spring (not shown) for urging the latch 13 in a direction to engage the striker 56. And a lever 14 having one end joined to the latch 13 and the other end extending to the outside of the housing 12.

The lever 14 includes a pair of operation knobs 16 via a pair of flexible wires 15a and 15b as shown in FIG.
It is connected to a and 16b. The operation knob 16a is the indoor 1
The operation knob 16b is disposed in the trunk room 9. By pulling the operation knob 16a or 16b, the latch 13 is rotated in the direction of the arrow in FIG. 3 to unlock the engagement with the striker 54. Let

As shown in FIG. 4, the seat back 5 is divided into a lower back main body 51 and an upper back main body 52, and the upper back main body 51 and the upper back main body 52 are divided into two parts.
Can be tilted backwards. The lower back main body 51 has a structure in which a cushion member 51b is arranged on one surface of a panel frame 51a and is covered with a skin material 51c such as vinyl chloride. The upper back portion 52 has a pipe-shaped main frame 52a and a reinforcing member. The cushion member 52c is arranged with the frame 52b as a core, and is covered with the same skin material 52d as the lower back main body 51.

Both ends of the main frame 52a are loosely fitted in a bracket 53 having a substantially U-shaped cross section provided at the upper end of the panel frame 51a, and are rotatably mounted by pins 54. The rotation range of the main frame 52a is regulated to about 90 ° by the tip of the bracket 53 and the stopper 55 provided in the bracket 53, and the upper buck portion 52 is lowered at the last tilted state. It stands upright with respect to the side back main body 51.

Therefore, for example, when storing a long article from the trunk room 9 side, the locking of the rear seat 4 is released by the operation knob 16a. As a result, the rear seat 4
As shown by the alternate long and short dash line in FIG. 1, the seat cushion 6 is tilted forward and tilted on the seat cushion 6. In this case, even if the front seat 2 is at the rearmost position, the seat back 5 is divided into two and the upper back portion 52 can be tilted rearward with respect to the lower back main body 51, so that the seat back 5 is moved forward. There is no longer the possibility of hitting the seat 2 and falling.

Further, since the upper back portion 52 is rotated by about 90 ° with respect to the lower back main body 51 to be in an upright state, it can be effectively used as a luggage stopper.

The upper back part 52 normally comes into contact with the front seat 2 and automatically stands up as shown in FIG. 1. However, a locking member is provided on the upper back part 52 to lock the front seat 2. Of course, it is possible to securely lock the upper back portion 52 in the upright state when the seat back 5 is tilted forward by the member.

<Effects of the Invention> As described above, according to the present invention, the seat back is divided into the lower back body and the upper back portion, and the upper back portion is rotated about 90 ° with respect to the lower back body. If you want to tilt the seat back forward, remove one locking device of the lower back body and tilt the lower back body forward so that the upper back part comes into contact with the front seat. It stands up and the height direction of the seat back is adjusted. As a result, the seat back of the rear seat can be surely tilted forward regardless of the front and rear positions of the front seat, and the trunk can be operated with one touch.

Further, when the seat back is in the forward tilted state, the upper buck portion stands upright with respect to the lower buck main body, so that the upper buck portion can effectively function as a luggage stopper.
