Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement in a vehicle seat assembly structure.

[0002]

[Prior Art]

 Conventionally, as shown in FIGS. 5 and 6, a so-called stationary seat type automobile seat 3 in which a seat cushion 2 is placed on a seat frame 1 and assembled is proposed.

[0003]

[Problems to be solved by the device]

 However, since the seat cushion 2 is simply placed on the seat frame 1, the seat cushion 2 may fall off the seat frame 1 during transportation. Therefore, as shown in FIG. 7, if fasteners (magic fasteners) 4a and 4b having hook-fastening portions that can be hooked with each other are provided on the upper surface of the seat frame 1 and the lower surface of the seat cushion 2, respectively, Although it can be prevented from falling off, there is a problem in that the mounting position is displaced depending on how the seat cushion 2 is placed. Further, when the seat cushion 2 is placed on the seat frame 1, there is a problem that the trim of the front edge portion 2a of the seat cushion 2 is rubbed and broken by the edge of the front rising edge 1a of the seat frame 1.

Therefore, an object of the present invention is to provide an assembling structure for an automobile seat in which the seat cushion does not fall off, the assembling position does not shift, and the trim does not break.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides an automobile seat to be assembled by placing a seat cushion on a seat frame, by providing an edge member which can be fitted to a front rising edge of the seat frame, and the edge member. Is sewn to the end of the extension trim extending from the front edge of the seat cushion with a sewing thread, and the seat cushion is fitted to the front rising edge of the seat frame with the edge member as a fulcrum of rotation. It is characterized by being placed on top of and assembled.

[0006]

[Action]

 According to the present invention, the edge member is sewn to the end of the extension trim extending from the front edge portion of the seat cushion with the sewing thread, and the edge member is fitted to the front rising edge of the seat frame, and the edge member is rotated. Place the seat cushion on the seat frame and assemble. As a result, the front edge portion of the seat cushion is fixed to the front rising edge of the seat frame through the extension trim and the edge member, so that the seat cushion does not fall off the seat frame and the position shift is prevented. Will not occur. Further, since the edge member is fitted to the front rising edge of the seat frame, the trim or extension trim of the front edge portion of the seat cushion is prevented from being rubbed by the edge of the front rising edge and torn.

[0007]

【Example】

 Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments. As shown in FIGS. 2 and 3, an inverted J-shaped edge member 11 having a hook portion 11a that can be fitted from above is provided on the front rising edge 10b of the seat frame 10 made of synthetic resin. As shown in FIG. 4, the edge member 11 is manufactured by extrusion molding a synthetic resin and cut into an appropriate length.

On the other hand, an extension trim 13 extending from the seat cushion 12 is provided at the front edge portion 12a of the seat cushion 12, and an end of the extension trim 13 has a direction in which the leg portion 11b of the edge member 11 is fitted. The outer surface of the lower part of the sewing machine is sewn with the sewing thread 14 at an appropriate pitch in the width direction.

In the above structure, as shown in FIG. 2, the hook portion 11 a of the edge member 11 is fitted into the front rising edge 10 b of the seat frame 10 from above.

Next, when the seat cushion 12 is rotated in the direction of the arrow using the fitted edge member 11 as a rotation fulcrum and the seat cushion 12 is placed on the seat frame 10 as shown in FIG. Complete.

Since the front edge portion 12 a of the seat cushion 12 is fixed to the front rising edge 10 b of the seat frame 10 via the extension trim 13 and the edge member 11, the seat cushion 12 is fixed from above the seat frame 10. It will not fall off and will not be displaced.

Further, since the edge member 11 is fitted into the front rising edge 10b of the seat frame 10 and the seat cushion 12 is rotated, the seat frame 10 can be assembled accurately, so that the assembling property is also improved. Furthermore, since the edge member 11 is covered and hidden by the extension trim 13, the appearance is also improved. Furthermore, since the edge member 11 made of synthetic resin is fitted to the front rising edge 10b of the seat frame 10, the edge rising edge 10b can also be taken as a measure for the edge, and the trim of the front edge portion 12a of the seat cushion 12 can be achieved. Also, the extension trim 13 is prevented from being rubbed by the edge of the front rising edge 10b and broken.

[0013]

[Effect of the device]

 As is clear from the above description, in the vehicle seat assembly structure of the present invention, the edge member sewn to the end of the extension trim extended from the seat cushion is fitted to the front rising edge of the seat frame. The seat cushion is mounted on the seat frame by using the edge member as a fulcrum for assembly. Therefore, the front edge of the seat cushion is fixed to the front rising edge of the seat frame through the extension trim and the edge member, so that the seat cushion does not fall off the seat frame and the position shift occurs. Disappear. Further, since the edge member is fitted to the front rising edge of the seat frame, the trim and extension trim of the front edge portion of the seat cushion are prevented from being rubbed by the edge of the front rising edge and broken.
