Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a seat for seats suitable for use in, for example, a car seat.

[0002]

[Prior art]

 Conventionally, as a seat for this kind of seat, there has been one as shown in FIG. In FIG. 4, reference numeral 1 is a pan (dish-shaped) seat frame made of a synthetic resin molded body, and a curl portion 2 which is bent outward is formed at an opening edge portion of the seat frame 1.

A plurality of clamp members 3 are fixed to the inner side surfaces of the seat frame 1 which face each other in the longitudinal direction by appropriate means. The ends 4a of the S-shaped springs 4 are supported by the clamp members 3 facing each other, and are stretched with an appropriate spring force.

As shown in FIG. 5, the seat frame 1 configured as described above includes a seat pad made of, for example, a synthetic resin molded body of a foam material or a lock material on the entire surface of the opening from above the S-shaped spring 4. 5 is installed. Specifically, the seat pad 5 described above has its bottom portion supported on the S-shaped spring 4, and the groove portion 6 formed on the outer peripheral portion of the seat pad 5 is press-fitted into the curl portion 2 at the opening edge portion of the seat frame 1 to be fixed. Has been done. The surface of the seat pad 5 and the entire seat frame 1 are covered with a trim cover 7 that serves as a skin.

[0005]

[Problems to be solved by the device]

 In the conventional seat for seats configured as described above, the corners of the seat pad 5 are cut off so as not to make strong contact with the clamp member 3 fixed to the seat frame 1 as shown in FIG. When the seat is in use, the cutout portion 5a formed by obliquely cutting the corner portion of the seat pad 5 is pressed against the ends of the clamp member 3 and the S-shaped spring 4, and the seat pad 5 is damaged from here. there were.

Further, since the conventional seat frame 1 has a structure in which the side plate is simply raised, the strength is not sufficient, and therefore the side plate 1a of the seat frame 1 is deformed such as falling down. There was also.

The present invention has been made to solve the above-described problems, and it is an object of the present invention to obtain a seat for a seat that can prevent damage to the seat pad and prevent deformation of the seat frame. To aim.

[0008]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the seat for seat according to the present invention has a plurality of clamp members fixed to the inner side surfaces of the side plates facing each other of a pan-shaped seat frame made of a synthetic resin molded body and facing each other. A seat seat in which an S-shaped spring is stretched over a clamp member, and a seat pad is supported over the protruding surface portion formed on the inner surface of the S-shaped spring and the seat frame. It is adapted to be fixed in a concave portion formed lower than the protruding surface portion.

[0009]

[Action]

 In the seat for seat of the present invention configured as described above, the clamp member is fixed to the concave portion formed lower than the projecting surface portion of the seat frame with which the seat pad abuts, so that the seat pad contacts the projecting surface portion of the seat frame. The seat pad does not come into contact with the clamp member that is in contact with and fixed to the concave portion lower than the projecting surface portion, whereby damage to the seat pad can be eliminated.

Further, by forming the projecting surface portion on the seat frame, the strength of the seat frame is improved, and deformation such as tilting of the side plate can be prevented.

[0011]

【Example】

 Hereinafter, embodiments of a seat for a seat according to the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a perspective view of a seat frame of a seat for seats according to this embodiment, FIG. 2 is an enlarged sectional view taken along line AA of FIG. 1, and FIG. 3 is an enlarged sectional view taken along line BB of the same. 4 and the same components as those of the conventional example described with reference to FIG.

A feature of the present invention is that the side plate 1a of the seat frame 1 to which the clamp member 3 for supporting the S-shaped spring 4 is fixed is formed in an inclined shape that is raised inward over its corners. The projecting surface portions 8 are formed, and the recesses 9 are substantially formed between the projecting surface portions 8. The above-mentioned clamp member 3 is fixed to the inner side surface portion of the recessed portions 9.

The seat frame 1 thus configured has a structure in which the clamp member 3 fixed to the recess 9 does not project from the above-mentioned projecting surface portion 8 to the inner surface side of the frame.

In the seat for seat according to the present invention configured as described above, the cutout portion 5 a of the seat pad 5 contacts the projecting surface portion 8 of the seat frame 1 when the seat pad 5 is supported on the S-shaped spring 4. Therefore, the cutout portion 5a of the seat pad 5 does not come into contact with the clamp member 3 fixed to the recess 9 of the seat frame 1 at all.

Therefore, even when the seat is actually used, the seat pad 5 does not come into contact with the clamp member 3 and the terminal 4a of the S-shaped spring 4 supported by the clamp member 3 and the excised portion 5a of the seat pad 5, Thus, damage to the seat pad 5 can be prevented in advance.

Further, in the seat frame 1, the strength of the seat frame 1 itself is improved by forming the projecting surface portion 8 from the side surface plate 1a to the corners thereof, and therefore, as in the conventional case. In addition, there is an advantage that the deformation such that the side plate 1a falls down can be eliminated.

The present invention is not limited to the embodiments described above and shown in the drawings, and various modifications can be made without departing from the scope of the invention.

For example, the seat for seats of the present invention can be widely applied to seat cushions and seat backs of automobiles and the like.

[0020]

[Effect of device]

 As described above, in the seat for seats according to the present invention, a plurality of clamp members are fixed to opposing inner side surfaces of a pan-shaped seat frame made of a synthetic resin molded body, and S-shaped springs are respectively attached to the opposing clamp members. In the seat for seats in which the seat pad is supported over the S-shaped spring and the inner surface of the seat frame, the clamp member is lower than the inner surface of the seat frame with which the seat pad abuts. Since the seat pad is fixed in the formed recess, the seat pad can be effectively prevented from being damaged by the end of the clamp member and the S-shaped spring supported by the clamp member, thereby improving the durability and reliability of the seat for a seat. There is an effect that it can be improved.

Further, by forming the projecting surface portion on the side surface plate of the seat frame, the strength of the seat frame itself is improved, and deformation such as the side plate falling down can be eliminated. Can always be maintained and the productability can be improved.
