る。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle seat back in which a bag-like seat cover is covered by a seat back frame via a cushion body having an open back. It is. 2. Description of the Related Art A conventional vehicle seat back generally has a flat rear surface. Recently, however, the foot space of a rear occupant has been increased to increase the space in the passenger compartment. In order to make the seat feel wider, those having a recess formed in the center portion of the back surface of the front seat have come to be used, but as means for forming the above-described recess,
Because both sides of the back of the back cover of the seat cover are fixed to the back frame with a number of resin hooks and fastener rubber, or the seat cover is drawn in using a back board formed in a concave shape, This means that special parts are required, the number of parts is increased, the assembly is troublesome, and workability is poor, and there is also a problem in terms of durability such as deformation due to long-term use. . [0003] The present invention solves the above-mentioned problems and reduces the number of parts and the number of parts required for a vehicle seat back that makes the interior of a vehicle interior feel wider. An object of the present invention is to provide a highly durable vehicle seat back which can be manufactured at a low cost, has a good appearance, and hardly deforms even when used for a long time. A vehicle seat back according to the present invention which has solved the above-mentioned problems has a bag-like seat cover covered by a seat back frame via a cushion body having an open back. In the vehicle seat back serving as the seat back body, bendable left and right vertical cores were attached to both sides of the back of the back cover of the seat cover, and an intermediate portion between the two vertical cores was released from the cushion body. The seat back frame is drawn into the seat back frame through the back and back portions, and the back cover portion of the seat cover is curved together with the two vertical cores, so that the back surface of the seat back body is formed in a front warped surface. In such an invention, in order to pull the middle portion of both vertical cores into the seat back frame through the open back portion of the cushion body, the middle portions of both vertical cores are connected to the connecting horizontal rod, and If you pull the middle part of both vertical cores into the seat back frame via the connecting horizontal rod,
It is more preferable because both vertical cores can be pulled in at the same time and workability is improved. Embodiments of the present invention will be described below with reference to the drawings. 1 is a seat back body, and the seat back body 1 is a seat back frame 3
A bag-shaped seat cover 5 is covered via a cushion body 4 made of a polyurethane foam or the like having a recess 2 with an open back. The seat back frame 3 includes left and right columns 3a, 3a and an upper beam 3b.
The lateral frame wire 6 is stretched at an intermediate position between the left and right columns 3a, 3a. The above-mentioned bag-shaped seat cover 5 is
The surface covering portion 5a, the right and left camachi covering portions 5b, 5b, and the back back covering portion 5c are stitched in the vertical direction, and the head is closed by an extension of the surface covering portion 5a. Further, connecting bands 8 and 8 are sewn to the stitching portion 7 between the left and right machichi covering portions 5b and 5b and the back and back covering portions 5c on both sides of the back surface of the back and back covering portion 5c, respectively. The left and right resilient vertical cores 9, 9 such as synthetic resin rods and piano wires are attached to the suturing portion 7 so that the sewn portions 7 and the vertical cores 9 are arranged in parallel at a distance of the connecting band 8. It will be.
The vertical cores 9, 9 are connected by a connecting horizontal rod 10 in the vicinity of the center. When the bag-shaped seat cover 5 is put on the seat back frame 3 on which the cushion body 4 is mounted, the connecting horizontal rod 10 is inserted into the open recess 2 on the back of the cushion body 4. By pulling it in and locking it to the frame wire 6 of the seat back frame 3 with the binding material 11, the intermediate portion between the left and right vertical cores 9, 9 attached to both sides of the back surface of the back back covering portion 5 c is seat backed. By being drawn into the frame 3, the back cover portion 5c of the seat cover 5 together with the two vertical cores 9 and 9 is curved in an arc shape, whereby the back surface of the seat back body 1 is formed into a front warped surface. In order to make it easier to cover the seat cover 5 with the bag-shaped seat cover 5, the lower part of the seam between the back and back cover 5c and the gusset cover 5b of the seat cover 5 is replaced with a slide fastener. It is preferable that a part of the seat cover 5 can be opened and closed. In the above-described embodiment, in order to improve workability, the vertical core 9 is attached to one end of a band-shaped cloth serving as the connecting band 8 so that an intermediate portion between the two vertical cores 9 is formed. The connecting rods 10 are connected to each other, and the connecting rods 10 are drawn into the open dents 2 at the back of the cushion body 4 and are locked to the frame wires 6 by the binding material 11, whereby the two vertical cores 9 are connected.
9 is bent, and the back core portion 5c of the seat cover 5 is bent along with the bending of the vertical cores 9 and 9 to form the back surface of the seat back body 1 on the front warp surface. Instead, the intermediate portion between the two vertical cores 9 may be directly drawn into the seat back frame 3 through the open back portion of the cushion body 1. [0010] With the above-mentioned structure, an intermediate portion between the bendable left and right vertical cores 9, 9 attached to both sides of the back of the back and back covering portion 5 c of the seat cover 5 is attached to the open back of the cushion body 4. By drawing in the seat back frame 3 through the portion, the back and back covering portion 5c of the seat cover 5 is bent together with the two vertical cores 9 and 9 so that the seat back body 1
Is formed on the front warp surface 5d, so that the space between the rear seat and the rear seat is widened by the amount of the front warp, so that the space in the vehicle interior can be felt wide. In addition, it can be manufactured with a small number of parts and a small number of steps. Although it is possible, the appearance is good and the vertical cores 9 and 9 are hardly deformed, so that they are not deformed even when used for a long period of time and have excellent durability. As is apparent from the above description, the present invention provides a vehicle in which a seat-back body is covered with a bag-shaped seat cover via a cushion body whose back and back are opened. In the seat back, a bendable left and right vertical core is attached to both sides of the back of the back cover of the seat cover, and an intermediate portion between the two vertical cores is drawn into the seat back frame through the opened back and back portion of the cushion body. By curving the back-and-back covering part of the seat cover together with both vertical cores, the back of the seat back body is formed on the front warp surface, so the vehicle seat back that makes the interior of the vehicle interior feel wide is small and the number of parts is small. It is easy to manufacture with a lot of work, has a good appearance, and has little durability even after long-term use. Can provide a feedback. Therefore,
The present invention greatly contributes to the industry as a solution to the problem of this type of conventional vehicle seat back.
