[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a rotatable seat back that can be fitted into an armrest storage portion formed on a seat back when not in use when the seat cushion is moved back and forth. The present invention relates to a vehicle seat incorporating an armrest.

[0002]

2. Description of the Related Art A vehicle seat in which a seat back whose angle changes in conjunction with the forward and backward movement of the seat cushion is connected to the rear portion of the seat cushion which can be moved forward and backward is disclosed in Japanese Utility Model Laid-Open Publication No. 62-129331. As is widely known, in order to incorporate a rotatable armrest that can be fitted into an armrest storage portion formed in the seatback when not in use in such a vehicle seat, it is necessary to use a Japanese Utility Model Application Publication No. -66334,
It is normal to provide a window hole-shaped armrest storage part whose periphery is closed in the middle part of the seat back, and to fit the armrest vertically up and down freely. However, providing a window-hole-shaped armrest storage part whose periphery is closed in the middle part of the seatback involves many inconveniences in manufacturing the seatback and also involves many problems in covering the seat cover, resulting in high cost.

[0003]

[Problems to be Solved by the Invention] For this reason, it is convenient to manufacture the seat back and cover the seat cover.
An attempt was made to reduce the cost by setting the armrest storage part in the middle of the seatback to a notch opened toward the lower edge of the seatback. However, a notch-shaped armrest storage opened to the lower edge of the seatback was attempted. When the rotatable armrest with its lower surface is an arc surface is fitted so that it can be easily rotated with respect to the part, the seat cushion is slid forward greatly and the seat back is tilted greatly, and the upper surface of the rear of the armrest and seat cushion are tilted. The problem that the gap between them is conspicuous has arisen.

[0004]

SUMMARY OF THE INVENTION The present invention is intended to solve the above-mentioned problems and to rearward the seat cushion even when the seat cushion is largely slid forward and the seat back is largely tilted. The purpose of the present invention is to provide a vehicle seat that can be mass-produced inexpensively without producing a gap between the upper surface and the seatback and the cover of the seat cover. In a vehicle seat having a seat back connected to a seat back whose angle changes in conjunction with the forward / backward movement of the seat cushion, an armrest storage portion opened toward a lower edge of the seat back is provided at an intermediate portion of the seat back. An armrest having an arcuate lower surface is rotatably fitted to the armrest, and the armrest on the rear upper surface of the seat cushion is fitted. The lower position of rest housing portion in which characterized in that a ridge having an arcuate contact surface that contacts always with the arc surface of the armrest.

[0005]

The vehicle seat is installed in the vehicle body in a conventional manner, and the seat cushion is moved back and forth as necessary to change the angle of the seat back, thereby obtaining a comfortable posture. There is no difference from the conventional vehicle seat in that the armrest fitted to the storage portion can be used by moving it forward.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. In the drawing, reference numeral 1 denotes a seat cushion which is mounted on a rail 2 so as to be able to move back and forth, and 3 is connected to a rear portion of the seat cushion 1 by means of a connection fitting 4 so that the angle changes in conjunction with the forward and backward movement of the seat cushion 1. The details of these mechanisms will not be described because they are not well-known, but an armrest storage section 5 opened toward the lower edge of the seatback 3 is provided in the middle of the seatback 3. Notched. Numeral 6 is approximately 90 up and down around the pin 7 at the lower end in
An armrest fitted so as to be rotatable in degrees, the lower surface of the armrest 6 is formed on an arc surface 8 so that the armrest 6 can be easily rotated, and the top of the arc surface 8 is formed on the seat cushion 1. Close to the rear upper surface. Reference numeral 9 denotes a raised portion formed on the rear upper surface of the seat cushion 1 below the armrest fitting portion 5, and the surface of the raised portion 9 is an arc-shaped contact surface which is always in contact with the arced surface 8 of the armrest 6. 10 is formed. In addition, the arcuate contact surface 1
0 is an arc surface 8 in a state where the armrest 6 is fitted in the armrest storage portion 5 when the seat back 3 is normally upright.
The upper surface of the armrest 6 and the rear of the seat cushion 1 even if the seat back 3 is tilted greatly with the forward movement of the seat cushion 1 as a shape as shown in FIG. There is no gap between them.

In the above-mentioned embodiment, the separately formed raised portion 9 is provided on the upper surface of the rear portion of the seat cushion 1. However, the raised portion 9 is formed on the upper surface of the rear portion of the seat cushion 1 in another embodiment shown in FIG. Needless to say, it may be integrally formed as in the above.

The above structure is installed in the vehicle body by a conventional method, and when the relationship between the seat back 3 and the seat cushion 1 is to be in a comfortable posture, the seat cushion 1 is moved forward. The angle of inclination with respect to the seat back 3 also changes, and when the armrest 6 is required, the armrest 6 fitted to the armrest storage portion 5 can be used by moving it forward, which is not different from the conventional vehicle seat. In the present invention, since the armrest storage portion 5 provided in the middle portion of the seatback 3 and fitted with the armrest 6 is a cutout shape opened toward the lower edge of the seatback 3, the periphery is closed. The seat back 3 is easier to manufacture and the seat cover can be sewn and covered more easily than the open window-shaped armrest storage section, resulting in significant cost reduction. . Moreover, the lower surface of the armrest 6 in the notch-shaped armrest storage portion 5 opened toward the lower edge of the seatback 3 is formed on an arc surface 8 so that the armrest 6 can be easily rotated. 8 is close to the arcuate contact surface 10 on the upper surface of the rear portion of the seat cushion 1, so that the armrest 6 can smoothly rotate and, of course, a gap is formed between the upper surface of the seat cushion 1 and the rear upper surface. There is no. Further, even when the seat cushion 1 is moved forward to change the inclination angle with respect to the seat back 3, the arc surface 8 of the armrest 6 in the notch-shaped armrest storage portion 5 and the arc shape of the rear upper surface of the seat cushion 1 are always present. Since the relationship with the contact surface 10 maintains the close state, the problem that a gap is formed between the two can be completely solved.

[0009]

As is apparent from the above description, in the present invention, since the lower surface of the armrest in the armrest storage portion is formed on an arc surface which is close to the arc-shaped contact surface on the rear upper surface of the seat cushion, Regardless of the positional relationship between the seat cushion and the seat back, the armrest can be smoothly rotated at any time, and no gap is formed between the seat cushion and the rear upper surface. In addition, the armrest storage section is a cutout that opens toward the lower edge of the seatback, so that the seatback is easier to manufacture and the seat cover is easier than a window-hole-shaped armrest storage section with a closed periphery. Sewing and coating are also easy and cost can be greatly reduced. Therefore, the present invention has an extremely large practical value as a solution to the problem of the conventional vehicle seat.
