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, there is known an automobile seat having armrests on both sides of a seatback. A general automobile seat is configured such that an upper side portion of a seat back is cut to have a narrow width, and an armrest is accommodated in the cutout portion. The lower end of the armrest is attached to the seat back so as to be pivotable back and forth.

[0003]

By the way, in the case of a rear seat having an armrest, when the seatback is to be tilted backward in order to bring the rear seat into a reclining state or a full flat state, the armrest is located at a rear portion of the seat. Or, it interferes with the trim that covers the interior side of the wheel house and cannot be defeated.

[0004] In view of the above, there is a conventional configuration 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, it is not possible to immediately change the rear seat because it is necessary to slide the rear seat forward.

[0005] Further, in order that the seat back can be tilted rearward 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 rearward. Some have done so. In this case, the armrest does not interfere with the wheel house, but since the armrest stands up, the armrest cannot be used as an armrest.

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

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, according to the present invention, there is provided a rear seat for an automobile in which armrests are arranged on both sides of a reversible seat back. At the lower part, a side cushion separate from the seat back is placed, and the front is fixed to the vehicle body so that the front is almost flush with the seat back in the normal sitting position. An armrest that can be rotated between a standing position that is flush with the floor and a horizontal forward position is provided .
Rear of the wheelhouse, a
The armrest is moved forward horizontally
Back of armrest and top of deck side trim
And deck side trim so that
Is formed with a flat upper surface.

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

In the case of the present invention , when the armrest is lowered 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 flat and wide space can be secured. This space can be used not only as an armrest, but also as a simple table or the like.

Is attached.

The left and right widths of the second board 12 and the third board 13 are the same as the length of the seat back 4a of the rear seat 4. Also, when the seat back 4a is horizontally tilted backward,
The front and rear widths of the first board 11 and the second board 12 are set so that the top of the seat back 4a coincides with the front edge of the third board 13. Furthermore, cushion pad 1
The thickness of 5 is set substantially equal to the thickness of the seat back 4a.

At the lower portion on both sides of the seat back 4a of the rear seat 4, a side cushion 4b separate from the seat back 4a is arranged. These side cushions 4b are also formed of cushion members similarly to the seat back 4a, and are fixed to the vehicle body 1 in a slightly backward tilted posture so that the front surface thereof is substantially flush with the seat back 4a in a normal sitting posture. . A lower end of an armrest 4c is pivotally connected to an upper end of the side cushion 4b. That is, the armrest 4c is rotatable between a slightly rearward standing position where the front surface thereof is substantially flush with the side cushion 4b and a horizontal forward position.

At the rear of the side cushion 4b, a box-shaped deck side trim 16 that covers the indoor side of the wheel house 7 (see FIG. 1) is arranged. The upper surface 16a of the deck side trim 16 is formed as a flat horizontal surface so as to be substantially flush with the rear surface of the armrest 4c when the armrest 4c is horizontally tilted forward (see FIGS. 3 to 6). ing.

FIG. 7 shows a mechanism for mounting the right side cushion 4b and the armrest 4c of the rear seat 4. Reference numeral 20 denotes a bracket. The upper end 21 bent horizontally rearward is fastened to the upper surface of the wheel house 7 by a nut 22, and the vertical intermediate portion 23 is fastened to the front surface of the wheel house 7 by a bolt 24. Further, a long hole 26 is formed in the lower end portion 25 which is horizontally bent forward, and a locking portion 27a of a frame 27 protruding from a rear surface of an upper end portion of the side cushion 4b is locked in the long hole 26, The upper end of the side cushion 4b is fixed. In addition, this hook part 27a is a deck side trim 1
6 is inserted into the inside of the deck side trim 16 through an opening hole 16b formed on the front surface of the
Hanged on. The other end 27b of the frame 27 protrudes from the lower end of the side cushion 4b, and the mounting bracket 28 is fixed to the end 27b. This bracket 2
8 is a bolt 3 together with the anchor 30 of the seat belt 29.
1 fastened to the side of the wheel house 7.

A pair of hinge portions 32 and 33 are formed on both sides of the intermediate portion 23 of the bracket 20 so as to be bent forward.
These hinge portions 32, 33 project forward through opening holes 16b formed in the front surface of the deck side trim 16. Shaft holes 32a, 33a through which the bolt 34 can be inserted are formed in the hinge portions 32, 33, and a nut 35 screwed with the bolt 34 is fixed to the shaft hole 32a of the inner hinge portion 32. The outside of the outer hinge portion 33 is covered with a hinge cover 36 made of resin so that the head of the bolt 34 is not exposed to the outside.

As shown in FIGS. 8 and 9, the armrest 4c is composed of a frame 40 serving as a framework and a pad 41 covering the outer periphery thereof. The frame 40 is made of a metal plate bent in a substantially U-shape toward the front.
Is fixed. As shown in FIG. 10, the friction spring portion 42a is formed so as to be elastically deformable in the width direction of the armrest 4c, and has a hole 42b in the center where the bolt 34 is inserted. The friction spring portion 42a is connected to the hinge portion 3 of the bracket 20.
The inner and inner surfaces 2 and 33 are brought into pressure contact with each other, and a sense of moderation at the time of rotation can be given by frictional force generated by a spring reaction force.

A guide pipe 43 for passing the bolt 34 is fixed inside the lower end of the frame 40 as shown in FIG. 11, and the holes of the guide pipe 43 correspond to the holes 42b of the friction spring portion 42a. I have. In addition,
In FIG. 11, the spring steel plate 42 is omitted. Further, two stopper pins 44, 45 extending in the width direction are fixed to the lower end of the frame 40, and the ends of the stopper pins 44, 45 projecting from the frame 40 are connected to the hinges 32, 3 respectively.
The rotation angle of the armrest 4c is restricted to about 110 ° by hitting the stopper portions 32b, 33b of the third arm.

At the lower end of the pad 41, a slit 46 into which the inner hinge 32 is inserted is formed. A reinforcing wire 47 is fixed to the frame 40 to reinforce the outer portion 41a with the slit 46 interposed therebetween.
Lower end of frame 40 and friction spring portion 42
a and the ends of the stopper pins 44 and 45 are exposed on the outer surface of the pad 41 and the inner surface of the slit 46. In particular,
Since the nut 35 fixed to the inner hinge portion 32 is screwed into 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-described structure will be described. 1 and 2
Is a case where the rear seat 4 is in a normal sitting posture, and the front surfaces of the seat back 4a and the side cushion 4b are flush. In this case, the armrest 4c is also raised so as to be flush with the seat back 4a and the side cushion 4b, so that a wide backrest area can be secured.

FIGS. 3 and 4 show a case where the armrest 4c is moved forward to the horizontal position and the rear seat 4 is reclined. By moving 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 wide armrest space can be secured. This space can be used as a simple table. In this case, even if the seat back 4a is reclined rearward, the armrest 4c does not interlock with the backward inclination of the seatback 4a, so that the armrest 4c does not interfere with the deck side trim 16 and always maintains a horizontal position. Can be.

FIGS. 5 and 6 show the case where the rear seat 4 is fully flat. In this case, the second board 12 is rotated rearward with the hinge 14 as a fulcrum, and the second board 12 is rotated.
The second board 12 is folded on the third board 13 so that the cushion pad 15 of the second board 13 faces upward. Then, the headrest 4d is pulled out from the seat back 4a, and the seat back 4a is tilted rearward to a horizontal position. As described above, when the seat back 4a is moved backward, the top of the seat back 4a is substantially in 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. Become. Therefore, a flat bed space can be created.

Also in this case, when the armrest 4c is tilted forward horizontally, the rear surface of the armrest 4c and the upper surface 16a of the deck side trim 16 are continuously flush.
Further, if a table plate is placed over the left and right armrests 4c and the deck side trim 16, it can be used as, for example, a table.

The present invention is not limited to the above embodiment. In the above embodiment, the armrest can only be tilted forward, 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. In the above embodiment, the luggage compartment space is provided at the rear of the rear seat. However, the present invention can be applied to a vehicle having a third row of seats disposed at the rear of the rear seat. Further, a slide mechanism may be provided so that the rear seat can slide back and forth.

[0025]

As is apparent from the above description, according to the present invention, the side cushion separate from the seat back is arranged at the lower portion on both sides of the seat back, and the upper end of the side cushion is positioned horizontally with the standing position. Since the armrest that can rotate between the front-rear position is attached, when the seatback is moved backward from the normal sitting position, the armrest does not interlock with the seatback and the armrest interferes with the rear side deck trim Nothing. Therefore, the operation of changing the seat back to the full flat posture or the reclining posture is very easy. Also, since the angle of the armrest can be adjusted to the forward position separately from the seat back, unlike the conventional armrest attached to the seatback, the armrest can be used as an armrest even in a full flat posture or reclining position . In addition, the present onset
In the case of light , the rear surface of the armrest and the upper surface of the deck side trim at the time of falling forward are substantially flush with each other, so that a large armrest space can be secured and the device can be used as a mounting table for a table or the like.
