BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seat cushion comprising a panel-type cushion frame for a vehicle or the like and a seat pad.

[0002]

2. Description of the Related Art As one type of a vehicle seat cushion, a thick seat pad 31 is placed on a panel-type cushion frame 30 as shown in FIG.
As shown in FIG. 1, in order to improve the cushioning property, a thin seat pad 44 is placed on a cushion frame 40 having a structure in which an upper frame 42 around which an S-shaped spring 41 is stretched is supported using a coil spring 43. Are known.

[0003]

In the seat cushion shown in FIG. 5, the panel-type cushion frame 30 has a simple structure, but a thick seat pad 31 is used to provide cushioning. However, there is a disadvantage that the sheet becomes thick and the amount of the pad material used increases. In addition, this kind of seat cushion using the cushion frame 30 and the seat pad 31 is not suitable for a low-height type passenger car, and the type of vehicle used is limited. Further, in the seat cushion shown in FIG.
Although 4 is thin, the cushion frame 40 requires an S-shaped spring 41, a coil spring 43, and the like, so that the cushion frame 40 has many components and tends to be heavy.

[0004] Further, in both seats, the flexing feeling cannot be adjusted according to the occupant's body shape and preference. Therefore, the present invention provides a seat cushion having cushioning properties by using a panel-type cushion frame having a simple configuration, and further provides a seat cushion capable of adjusting the amount of bending according to a occupant's body shape and preference. The purpose is to do.

[0005]

Accordingly, a first invention of the present application is to provide a seat cushion constituted by placing a seat pad on a panel-type cushion frame, wherein the panel-type cushion frame is mounted on a floor side of a vehicle body. A front panel frame supported, a rear panel frame rotatably connected to a rear end of the front panel frame so as to be vertically rotatable, and a rotation restricted by connecting the front panel frame and the rear panel frame. And an elastic member.

A second invention is a seat cushion constructed by placing a seat pad on a panel-type cushion frame. The panel-type cushion frame is a front panel frame supported on a floor side of a vehicle body. A rear panel frame rotatably connected to a rear end of the front panel frame in a vertical direction; an elastic member connecting the front panel frame and the rear panel frame to restrict rotation; Adjusting means for adjusting the elasticity characteristics of the member.

[0007]

In the seat cushion of the present invention, a rear panel frame is rotatably connected to a front panel frame fixed to the floor side of the vehicle, and both panel frames are rotated by elastic members. Because it is connected so as to regulate, when a load is applied to the rear panel frame such as when a person is seated, the rear panel frame can swing up and down by the elastic member with the connecting part as a pivot point, The panel-type cushion frame itself having a simple configuration can obtain a flexing feeling without using a thick cushion pad or a heavy spring.

In the second invention, there is further provided an adjusting means for adjusting the elasticity characteristic of the elastic member, whereby the vertical swing amount of the rear panel frame is increased or decreased by adjusting the elasticity characteristic. It is possible to adjust the amount of deflection of the seat cushion according to the body shape and preference of the seated person.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a vehicle seat using the seat cushion according to the present invention.
It comprises a panel-type cushion frame 10 and a cushion pad 11 (see FIG. 4) placed thereon.

FIG. 2 is a perspective view of a panel type cushion frame 10 used in the vehicle seat of FIG. 1, and FIG. 3 is an enlarged perspective view of a portion A shown in FIG. A frame 12 and a rear panel frame 13 form a schematic outer shape, and both left and right sides of the panel frames 12 and 13 are cushion pads 11.
Are provided so that they can be fitted. The front panel frame 12 uses the fixing member 14 to slide on the seat track 15 on the floor side of the vehicle body.
The rear panel frame 13 is connected to the rear end of the side surface of the front panel frame 12 by a hinge pin 17 so as to be vertically rotatable.

Here, the rotation of the rear panel frame 13 is restricted by providing a spring 18 by connecting the respective side surfaces of the front panel frame 12 and the rear panel frame 13 to each other. In this embodiment, both ends of the spring 18 pass through a long hole 12a formed in the front and rear sides of the front panel frame 12 and extend in the front-rear direction, and can be slid in the long hole 12a; It is supported by a spring support pin 20 provided on the frame 13. As an adjusting means for adjusting the elasticity characteristic of the spring 18, a nut 21 to which the spring support rod 19 is fixed and a screw 22 extending in the front-rear direction to which the nut 21 is screwed are fixed to the front panel frame 12. The nut 21 slides on the screw 22 by rotating the screw 22 using the rotating handle 23, whereby the spring support rod 19 is integrally provided.
Move in the longitudinal direction in the elongated hole 12a so that the position of the spring support rod 19 can be adjusted.

By configuring the seat cushion of the present invention in this manner, when a load is applied to the rear panel frame 13 such as when a person is seated, the rear panel frame 13 uses the hinge pin 17 as a rotation fulcrum and the spring 18
Can be swung up and down by the elasticity of (see FIG. 4),
It is possible to obtain a flexing feeling with a cushion frame itself having a simple configuration without using a thick cushion pad or a heavy spring.

Further, there is provided means for adjusting the resilience characteristic of the spring 18 having a nut 21 to which the spring support rod 19 is fixed and a screw 22 supported by a bracket 24 fixed to the front panel frame 12 as main components. The rotation of the screw 22 causes the spring 1
8, the elasticity of the spring 18 can be adjusted, so that the spring supporting rod 19 can be slid forward of the seat to increase the tension of the spring 18.
3 can be reduced, and conversely, if the tension of the spring 18 is reduced by sliding the spring support rod 19 to the rear of the seat, the vertical swing of the rear panel frame 13 is increased. It is possible to adjust the amount of deflection of the seat cushion according to the occupant's body type and preference.
