Description

[Detailed description of the invention] (Field of industrial application) This invention relates to the seat back structure of vehicle seats (particularly automobile seats), and more specifically, to the improvement of the skin member covering the seat back with a hollow part formed in the center. This is related.

(Prior art) This type of seat back structure for automobile seats is the fifth
This will be explained based on FIGS. 7 to 7. In the same figure, 1
1 is an automobile seat consisting of a seat cushion 2 and a seat back 3, and the seat back 3 has a hollow part 4 formed therein. A lid member 5 is pivotally attached to the hollow part 4 so as to be tiltable toward the rear seat, and opens and closes the hollow part 4. The seat back 3 has left and right side parts 3.
Inside a, 3b, frame lines 6, 6, 6, 6 are arranged at the four corners, and a frame 7 is arranged on the rear outside. Then, seat back left and right side parts 3
A pad member 8 and a skin member 9 covering the pad member 8 are attached from the backrest surface side to the outer surface side of a and 3b. Padded member 8
The ends of the skin member 9 and the skin member 9 are attached to the frame line 6 of the frame 7 by being tied to the frame line 6.

Further, on the inner side (the hollow side) of the left and right side parts 3a and 3b of the seat back, a skin 10 forming the skin member 9 has one end 10a tied to the skin member 9 on the backrest side, and the other end 10b It is fastened and attached to the rear inside of the frame line 6 with a hook ring A.
On the rear surface of the left and right side parts 3a, 3b and the upper part 3c of this seat bag 3, a U-shaped board material 11 made of a synthetic resin material is provided to cover the rear surface, outer surface, and inner surface of the left and right side parts 3a, 3b. It is arranged.

(Problems to be Solved by the Invention) The seat back structure of the above-mentioned automobile seat has a hollow portion 4 formed in the seat back 3, and the seat back 3
A board material 11 was disposed on the left and right side parts 3a, 3b and the rear part of the upper part 3c of the seat bag 3, and the inside of the left and right side parts 3a, 3b of the seat bag 3 was covered with the board material 11 made of a synthetic resin material. There is a risk that rear seat occupants may hit their bodies against this hard board material 11 and be injured due to vibrations, etc.
Since the hollow portion 4 is formed in the seat bag 3, it takes time to cover the skin members 9 on the left and right side portions 3a, 3b of the seat bag 3, making it impossible to perform the work efficiently.

This invention was made to solve this problem, and even if a passenger in the rear seat hits the rear side of the left and right sides of the seat bag, the impact can be absorbed, and the impact can be absorbed. An object of the present invention is to obtain a seat back structure for a vehicle seat that allows efficient covering of skin members on the left and right sides of the seat back.

(Means and effects for solving the problem) The seat back structure for a vehicle seat according to the present invention includes a cushion member disposed on the back side and back side of the seat back, and a skin member covering the cushion member. A fastener member that connects the front and rear parts of the skin member is attached to the surface on the side of the hollow part, and by closing this fastener member, the front and rear parts of the skin member can be connected.

(Example) An example of this invention is shown in Figures 1 to 4.
This will be explained based on the diagram. In the figure, 12 is a car seat, with a seat cushion 13 and a seat back 14.
The seat bag 14 is attached to the seat cushion so as to be tiltable in the front-rear direction.
This seat bag 14 has a hollow part 15 formed in its center, and the lower part of the lid member 16 is attached to this hollow part 15 in a pivotally supported manner. This lid member 16 enables communication between the front and rear of the seat bag 14 by opening and closing the hollow portion 15 of the seat bag 14. A frame 18 and frame lines 19, 19, 19 are disposed at the four corners of the left and right sides 17, 17 of the seat bag 14. A pad member 20 is disposed between the front frame lines 19, 19 along the outer surfaces of the left and right side parts 17, 17, and a pad member 20 is disposed between the rear frame line 19 and the frame 18. Same hard pad member 2
1 are disposed along the outer surfaces of the left and right side parts 17, 17, and a pad member 20 and a hard pad member 21 are attached to the front and rear sides of the left and right side parts 17, 17. The front pad member 20 and the rear hard pad member 21 are covered with a skin member 22. This skin member 22 is the front pad member 2.
The 0 side consists of a skin 23 and a urethane slab material 24, and the outer surface, inner surface, and rear surface are formed by the skin 23. Furthermore, a fastener member 25 is attached to the inner side of the skin member 22 along the approximate center thereof. This fastener member 25 is disposed along the approximate center of the left and right inner surfaces 22a, 22b, upper inner surface 22c, and lower end surface 22d of the skin member 22. That is, this skin member 22 covers the seat back 14 and also covers the hollow portion 1.
A fastener member 25 is attached to the inner surface where 5 is formed. Note that 26 is a bead and is disposed at a corner of the skin member 22. Further, 27 is a lock hole formed in the seat back 14, and a lock hole 27 is formed in the cover member 16.
This is for locking the locking member 28 of.

The seat back structure for an automobile seat having the above configuration includes a pad member 20 and a hard pad member 21 mounted on the backrest surface and the back surface of the left and right side portions 17, 17 of the seat back 14.
0 and 21 are covered with a skin member 22, and a fastener member 25 is attached to the inner surface of this skin member 22 in which the hollow portion 15 is formed, so that passengers in the rear seats can easily move their bodies against the seat back 14 due to vibrations of the car, etc.
Even if the seatback hits the rear surface, the impact is absorbed by the hard pad members 21 on the left and right sides 17, 17 of the seat back, improving safety.
When the cover is closed, the work of covering the skin member 22 is easily completed, and work efficiency is improved. Furthermore, since the skin members 22 of the seat back 14 can be formed from the same material, the appearance is improved.

In the above embodiment, the fastener member 25 attached to the skin member 22 is of an open/close type, but it may be of a velvet type.

(Effects of the invention) According to this invention, a seat back structure for a vehicle seat that provides the following effects can be obtained.

Since the cushion material is placed at the rear of the seat bag (on the rear seat side), even if a passenger in the rear seat bumps into the seat, the cushion material will cushion the impact.

The seat back can be covered with the same skin member, and the appearance is improved.

Since the work of covering the skin member is completed by simply closing the fastener member of the skin member, work efficiency can be improved.
