Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an armrest structure for an automobile rear seat.

[0002]

2. Description of the Related Art Conventionally, as disclosed in Japanese Utility Model Laid-Open No. 62-6137, a vehicle seat having armrests on both sides of a seat back is known. A general automobile seat is configured such that an upper side portion of a seat back is cut out to have a narrow width, and an armrest is housed in the cut portion. The lower end of the armrest is attached to the seat back so as to be rotatable forward and backward.

[0003]

By the way, in the case of a rear seat with an armrest, since the rear seat is in a reclining state or a full flat state, when the seat back is tilted rearward, the armrest is located at the rear part of the seat. Or it cannot be knocked down because it interferes with the trim that covers the inside of the wheel house.

In view of this, there is a conventional one in which the seat back can be tilted backward only when the rear seat is slid forward. However, in this case, even if an attempt is made to change from the normal use state to the full flat state, the rear seat needs to be once slid forward, and therefore the change cannot be made immediately.

Further, since the seat back can be tilted backward without sliding the rear seat forward, the armrest can be tilted forward with respect to the seat back and then the seat back can be tilted backward. Some have done so. In this case, the armrest does not interfere with the wheel house, but since the armrest stands upright, the armrest cannot be used as an armrest.

Therefore, an object of the present invention is to provide an armrest structure for a rear seat, which prevents interference between the armrest and the wheel house, and can easily change from a normal sitting posture to a full flat posture or a reclining posture. Another object of the present invention is to provide a rear seat armrest structure in which the armrest can be used as an armrest or the like even when the seatback is tilted backward.

[0007]

In order to achieve the above object, the invention according to claim 1 is a rear seat for an automobile in which armrests are arranged on both sides of a seatback which can be tilted backward. The side cushion, which is separate from the seat back, is placed at the bottom, and the front cushion is fixed to the vehicle body so that its front surface is almost flush with the seat back in the normal sitting posture. The armrest is provided so as to be rotatable between an upright position which is flush with a horizontal forward position. The invention according to claim 2 is the invention according to claim 1, wherein a deck side trim for covering the indoor side of the wheel house is provided at the rear portion of the side cushion, and when the armrest is tilted horizontally forward, The upper surface of the deck side trim is flat so that the upper surface of the deck side trim is substantially flush with the upper surface.

When the seat back of the rear seat is tilted backward, only the seat back is tilted because the armrest is separate from the seat back and attached to the vehicle body.
Therefore, without sliding the rear seat forward,
The armrest does not interfere with the wheel house at the rear of the rear seat, and the seat back can be easily tilted backward. Further, even when the seat back is tilted backward to be in the reclining posture or the full flat posture, the armrest can be adjusted to the upright position and the front horizontal position regardless of the angle of the seat back. Therefore, even in the reclining posture or the full flat posture, the armrest can be used as an armrest or the like.

According to the second aspect of the invention, when the armrest is tilted to the front horizontal position, the rear surface of the armrest and the upper surface of the deck side trim are substantially flush with each other, so that a wide flat space can be secured. . This space can be used not only as an armrest, but also as a simple table or the like.

At the lower end of the pad 41, a slit 46 into which the inner hinge portion 32 is inserted is formed. A reinforcing wire 47 is fixed to the frame 40 in order to reinforce the outer side portion 41 a with the slit 46 interposed therebetween.
The lower end portion of the frame 40 and the friction spring portion 42
The ends of a and the stopper pins 44 and 45 are exposed on the outer surface of the pad 41 and the inner surface of the slit 46. Especially,
Since the nut 35 fixed to the inner hinge portion 32 is screwed with the bolt 34 inside the slit 46, the fastening portion is not exposed to the outside, and the appearance quality is improved.

Next, a method of using the rear seat 4 and the armrest 4c having the above construction will be described. 1 and 2
Shows the case where the rear seat 4 is in a normal sitting posture, and the front surfaces of the seat back 4a and the side cushions 4b are flush with each other. In this case, a wide backrest area can be secured by raising the armrest 4c so as to be flush with the seat back 4a and the side cushion 4b.

3 and 4 show the case where the armrest 4c is tilted forward to the horizontal position and the rear seat 4 is reclining. By tilting the armrest 4c forward, the back surface of the armrest 4c and the upper surface 16a of the deck side trim 16 are flush with each other, so that a large armrest space can be secured. It is also possible to use this space as a simple table. In this case, the armrest 4c does not interlock with the rearward inclination of the seatback 4a even when the seatback 4a is reclining backward, so that the armrest 4c does not interfere with the deck side trim 16 and always keeps the horizontal position. You can

5 and 6 show the case where the rear seat 4 is full flat. In this case, the second board 12 is rotated rearward with the hinge 14 serving as a fulcrum, and the second board 12 is rotated.
The second board 12 is folded back on the third board 13 so that the cushion pad 15 of FIG. Then, the headrest 4d is pulled out from the seat back 4a, and the seat back 4a is tilted backward to a horizontal position. As described above, when the seat back 4a is tilted backward, the top of the seat back 4a comes into substantially contact with the front surface of the cushion pad 15, and the upper surface of the seat back 4a and the upper surface of the cushion pad 15 are substantially flush with each other. Become. Therefore, a flat bed space can be created.

Also in this case, by tilting the armrest 4c forward horizontally, the back surface of the armrest 4c and the upper surface 16a of the deck side trim 16 are flush and continuous.
Further, if a table board is laid over and placed on the left and right armrests 4c and the deck side trim 16, it can be used as a table, for example.

The present invention is not limited to the above embodiment. In the above embodiment, the armrest can be tilted forward only, but the angle may be adjustable. Further, a lock mechanism for locking the armrest at two positions of the horizontal position and the standing position may be separately provided. Further, although the luggage compartment space is provided in the rear portion of the rear seat in the above-described embodiment, the present invention can be applied to a vehicle in which the seat of the third row is arranged in the rear portion of the rear seat. Further, a slide mechanism may be provided so that the rear seat can be slid back and forth.

[0025]

As is apparent from the above description, according to the present invention, the side cushions which are separate from the seat back are arranged at the lower portions of both side portions of the seat back, and the upper side portions of the side cushions are aligned horizontally with the standing position. Since the armrest that can be rotated between the forward and backward positions is installed, when the seatback is tilted backward from the normal sitting posture, the armrest does not work with the seatback and the armrest interferes with the rear side deck trim. Never. Therefore, the work of changing the seat back to the full flat posture or the reclining posture is very easy. Also, because the angle of the armrest can be adjusted to the forward tilt position separately from the seat back, unlike the conventional armrest attached to the seat back, the armrest can be used as an armrest even in a full flat position or a reclining position. . Further, in the case of the invention according to claim 2, since the rear surface of the armrest and the upper surface of the deck side trim are substantially flush with each other when tilted forward, it is possible to secure a wide armrest space and also as a platform for a table or the like. It is also possible to use.
