Description

[Detailed Description of the Invention] The present invention relates to an edge member for securing a skin material to a vehicle seat or the like.

In cab-over vehicles, the seat is located above the engine, and a common structure is to attach a seal rubber to the seat frame to seal the edge of the inspection opening provided above the engine. be. On the other hand, it is also common practice to fix the skin trim to the seat frame by fixing a trim attachment member that has an attachment part to the seat frame to the skin trim, and then attaching this trim attachment member to the seat frame. Conventionally, the seal rubber and the trim attachment member were manufactured separately and were attached to the seat frame close to each other, requiring a lot of installation time.

The present invention has focused on this point and has been devised for the purpose of reducing the labor involved in manufacturing and mounting. , an elastic seal portion protruding outward from the central portion of the attachment portion, and a skin trim attachment portion formed at the edge of one side piece of the attachment portion, and these sheets The present invention provides an edge member for attaching a skin trim, in which a frame attachment part, a seal part, and a skin trim attachment part are integrally formed. In other words, the edge member of the present invention has both the functions of a conventional seal rubber and a trim attachment member, and by attaching the skin trim to the seat frame with the skin trim fixed to the skin trim attachment part, the skin trim can be easily removed. At the same time as the seal portion is fixed to the seat frame, the seal portion is automatically attached to the seat frame. Therefore, compared to the conventional example in which the seal rubber and the trim mounting member were separate parts, the manufacturing and mounting effort can be reduced by almost half.

Next, an embodiment of the present invention will be described with reference to FIGS. 1 to 3. It should be noted that the present invention was conceived in connection with a seat device for a cab-over type automobile, and the embodiments are also related to this, but it goes without saying that the present invention can be applied to seats for other uses.

FIG. 1 is a schematic diagram of the cabin portion of a cab-over type automobile using the edge member according to the present invention. There is. A steering device 5 and a speed change lever 6 are arranged inside the cabin 1, and the floor panel 2 is raised in a stepped manner behind the speed change lever 6 to form a seat mounting portion 2a. Seat mounting part 2
In a, an opening 7 for engine inspection is formed in the floor panel 2, and a sheet 8 is attached to cover this opening 7. The rear edge of the seat frame 9 of the seat 8 is attached to the floor panel 2 by a hinge 10, and the front edge is provided with a locking hook 11, with which a floor-side locking device 12 engages. An edge member 15 according to the present invention is attached to the lower edge of the seat frame 9 to seal the edge of the opening 7.

FIG. 2 is a sectional view of the sheet 8 at a portion where the edge member 15 is attached, and FIG. 3 is an enlarged sectional view of the edge member 15. The edge member 15 includes an attachment portion 16 to the seat frame having a substantially U-shaped cross section and two opposing side pieces 16a and 16b.
a pipe-shaped seal part 18 formed at the tip of a connecting piece 17 protruding outward from the central part of the body, and a skin trim attachment part 19 formed at the end edge of one side piece 16a by extending it. It is equipped with a mounting part 16, a seal part 18, and a skin trim mounting part 19.
is formed in one piece. A plurality of locking pieces 20 are protruded from the inner surface of the mounting portion 16 and are inclined in directions facing each other, and a core member 21 having a U-shaped cross section is further embedded to ensure the necessary mounting force to the seat frame. It's like this. The edge member 15 is obtained, for example, by continuous extrusion molding of polyvinyl chloride, and the core material 2
As the material 1, a highly elastic metal plate is used.

When using the edge member 15, first, a skin trim 26 made of a skin material that covers the pad 25 of the seat 8 is attached to the skin trim attaching portion 19 using staples 27, for example. Note that this attachment can also be done by other means. Next, the mounting portion 16 may be clamped to the lower edge 9a of the seat frame 9, and the mounting to the seat frame 9 is thus completed. Since the skin trim attachment part 19 is on the extension line of the side piece 16a, the tensile force on the skin trim 26 acts in a direction parallel to the surface of the seat frame 9 at a position close to the seat frame 9.
No force is generated that would cause the edge member 15 to separate from the seat frame 9, and the edge member 15 is securely attached to the seat frame 9. At this time, since the seal part 18 is in a state of protruding downward from the center part of the mounting part 16, the seal part 18 is pressed against the floor panel 2 by the engagement of the hook 11 and the locking device 12, and the seal part 18 is properly pressed against the floor panel 2. In the compressed state, the edges of the opening 7 are sealed.

As mentioned above, the edge member of the present invention has both the functions of a seal rubber and a trim attachment member, so the seal rubber and trim attachment member can be attached by repeating the same operation at positions close to each other on the seat frame. There is no need to install the parts separately, which reduces the number of installation steps by almost half, and it is easy to assemble by simply inserting the mounting parts into the frame.
This also eliminates the hassle of manufacturing and parts inventory management.
