DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cushion mounting structure applied to, for example, a van-type automobile seat.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 3, in a seat (1) of a van type automobile, a cushion frame (3) installed on a slide mechanism (2) laid on a floor (5). A cushion material (4) made of a polyurethane foam or the like is placed on the top, and an engagement portion (4A, 4A) is formed at the edge of the cushion material (4).
B), and the cushioning material (4) is fixed on the cushion frame (3) by engaging the engaging portions (4A, 4B) with the edges of the frame (3).

[0003]

However, in the above-mentioned conventional construction, the interference between the engaging portion (4B) of the cushioning member (4) and the vehicle body side wall (6) on the vehicle body side wall (6) side. To avoid this, the shape of the engaging part (4B) becomes shallower,
The cushion (4) cannot be firmly engaged with the edge of the frame (3), and when the trim cover is attached to the cushion (4) or when a person sits down, the cushion (4) is ).

[0004]

The present invention provides a cushion frame (3) for solving the above-mentioned conventional problems.
A cushion material (4) is placed on the upper surface, and a wire hook (7) built in the cushion material (4) is attached to one or both edges of the cushion material (4) by the frame (3). The mounting structure of the cushion material (4) in the seat engaged with the edge is provided, and the wire hook (7) is attached to the cushion material.
It is intended to provide a mounting structure for the cushion material (4) in a seat previously inserted in a foaming mold when foaming (4).

[0005]

[Function] The cushion material (4) placed on the cushion frame (3) has the wire hook (7) built into the cushion material (4) at the edge thereof attached to the edge of the frame (3). Engagement secures the frame (3). Since the wire hook (7) has a small diameter,
It does not interfere with (6), and the engagement between the wire hook (7) and the edge of the frame (3) becomes strong.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to an embodiment shown in FIGS.
(5) The cushion member (4) made of polyurethane foam or the like is placed on the slide mechanism (2) laid thereon, and the cushion frame (3) is placed on the cushion frame (3). The cushion material
(4) is a hook made of wire on the side of the vehicle body side wall (6)
(7) is built in, and the hook (7) is fixed by engaging the edge of the frame (3) .On the opposite side, an engaging portion (4A) is formed, and the engaging portion (4A) is formed. 4A) the frame
It is fixed by engaging the edge of (3). In addition, a pull groove (4C) of the trim cover and the like are formed on the upper surface of the cushion material (4).

In the above construction, on the side of the vehicle body side wall (6), the wire (7) is firmly engaged with the edge of the frame (3) without interfering with the side wall (6). On the opposite side, the shape of the engaging portion (4A) is deepened to secure firm engagement with the edge of the frame (3).

The cushioning material (4) is manufactured by filling a foaming mold with a foaming material such as a foaming urethane material and foaming.
(7) is inserted in the foaming mold in advance. In this manner, the wire hook (7) is integrally built in the cushion (4).

[0009]

Thus, in the present invention, the cushioning material of the seat can be firmly fixed on the frame while avoiding interference with the vehicle body side wall.
