Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a seat cushion for a vehicle seat (automobile seat), and more specifically, to an improvement of an insert wire disposed within a cushion part of a seat cushion. It is something.

(Prior Art) A conventional seat cushion of this type of automobile seat will be explained based on FIGS. 5 and 6. This figure is a cross-sectional view of the seat cushion 1, in which a spring support member 3 is stretched between a frame 2, and a foam part 4 is molded on the spring support member 3. The foam pad 4 was placed thereon and covered with a skin member 5, and the end 5a of the skin member 5 was tied to the frame 2 with a hogging ring 6 (FIG. 5).

Furthermore, an insert wire 7 is embedded in the foam part 4 along its outer periphery in order to perform molding of the seat and support function during seating.
Further, in the case of the seat cushion 8 shown in FIG. 6, the frame-like frame consists of a pipe 9, and a wire 9a is attached to this pipe 9 in order to connect the end 5a of the skin member 5.

(Problems to be Solved by the Invention) In the conventional seat cushion for automobile seats, when the end 5a of the skin member 5 is tied to the frame-shaped frame 2 by the hogging ring 6, the frame-shaped frame 2
It is necessary to provide a stop point for tying, and tying can only be done at that point, making the tying work labor-intensive. In addition, if the frame is formed from a pipe 9, this pipe 9
In order to bind the end 5a of the skin member 5 to the pipe 9, a wire 9a for binding is attached to the pipe 9, which requires labor. Further, the insert wire 7 of the foam part 4 is buried along the outer periphery of the part 4 only for molding the seat, and the other wire 9a is buried at the end 5a of the skin member 5.
Because it is attached as a tie-down, there are many parts and the cost is high.

This idea was made to solve this problem, and by using the wires installed in the pads for shaping the seat and for binding the ends of the skin members, it is economical and has good workability. The object of the present invention is to obtain a seat cushion for a vehicle seat.

(Means for Solving the Problems) The seat cushion of the vehicle seat according to the present invention has the front and rear parts of the insert wire placed on the lower surface of the cushion part, and the left and right parts placed close to the top surface of the cushion part. It is arranged in

(Function) Therefore, since the front and rear parts of the insert wire are arranged on the lower surface of the cushion pad, the ends of the skin member covering the cushion pad can be fixed to the front and rear parts by hogging or the like. Since the left and right sides of the insert wire are buried close to the upper surface of the cushion pad, the shape of the cushion pad is determined.

(Embodiment) An embodiment of this invention will be described based on FIGS. 1 to 4. In the figure, reference numeral 10 denotes an automobile seat, which consists of a seat cushion 11 and a seat back. The seat cushion 11 shown in FIGS. 2 and 3 has a spring support member 1 between the frame-like frame 12.
3 is stretched, a molded foam part 14 is placed on this spring support member 13, and this foam part 14 is covered with a skin member 15. An insert wire 16 formed by bending a single wire into an annular shape is embedded in the foam pad 14 along its outer periphery. The insert wire 16 has left and right side parts 16a, 16a disposed along the left and right outer peripheries of the foam part 14 at positions close to the upper surface of the foam part 14, and a rear part 16b and a front part 16c located near the upper surface of the foam part 14. installed on the bottom surface of the Rear part 16b of insert wire 16
protrudes from the lower surface of the foam pad 14 and extends toward the inner surface of the frame 12. Further, the front side portion 16c of the insert wire 16 is formed along the seating surface side of the foam pad 14 toward the lower surface thereof, extends to the lower surface of the foam pad 14, and is disposed on the inner surface side of the frame 12. Ru.

Then, the front side portion 16c of the insert wire 16
Terminals 15a of the skin member 15 are tied to the rear side portion 16b with hogging rings 17, respectively.

According to the seat cushion 11 of the automobile seat having the above configuration, the left and right side portions 16a, 16a of the insert wire 16 function as molding of the seat and support portions when an occupant is seated, and the front and rear side portions 16c,
16b functions as a binding part for binding the end 15a of the skin member 15, and the insert wire 16
It is economical because it can be used effectively.

Furthermore, the front and rear side portions 16 of the insert wire 16
Since the terminal end 15a of the skin member 15 can be fixed to b, 16c, the positioning work for fixing the fixing as in the conventional case is not necessary, and the labor can be reduced. Furthermore, since the front side portion 16c of the insert wire 16 is arranged along the lower surface from the seating surface of the foam pad 14, when a load is applied to the left and right side portions 16a, 16a of the insert wire 16, the left and right side portions 16a, The cushioning function of the seat 16a is improved, and the occupant can feel a good seating feeling when seated.

A seat cushion 21 shown in FIG. 4 has the same structure as the embodiment described above, but the outer frame is formed from a pipe 22.

According to this seat cushion 21, the same effects as in the above-mentioned embodiments are achieved, and the wire for the skin member for fixing the end 25a of the skin member 25 to the pipe 22 is not required as in the conventional case.
It is possible to reduce the number of work steps.

(Effect of the invention) As explained above, this invention forms the front and rear side parts of the insert wire provided in the cushion part on the lower surface of the cushion part, and stops the ends of the skin member covering the cushion part on the front and rear sides of the insert wire. Due to the simple structure of the seat cushion, it is possible to provide a seat cushion for a vehicle seat that is easy to work with and is economical.

Further, since the left and right side portions of the annular insert wire are buried close to the upper surface of the cushion pad, the shape of the upper surface of the left and right side portions of the cushion pad can be maintained constant and deformation thereof can be prevented.
