Abstract

A clip fixing jig for fixing a clip member in a molding die for molding a seat pad has a wall part erected along a whole outer peripheral edge of a bottom part thereof. The wall part forms, above the bottom part, an accommodation space for accommodating extending parts. The clip fixing jig has fixing parts for detachably fixing a clip member, so that a clip member can be fixed to the clip fixing jig by inserting the clip member in the accommodation space. With a clip fixing jig provided in a molding die, a seat pad can be formed by insert molding, so that workability in clip member fixing work is improved.

Claims

1. A clip fixing jig for fixing a clip member in a molding die for molding a seat pad, the clip member having a buried part to be buried in the seat pad provided with a groove portion to accommodate a portion of a seat cover, an extending part extending from the buried part into the groove portion, and a claw-like part formed to project from an end portion of the extending part and to catch a locking part provided on a reverse side of the seat cover, the clip fixing jig comprising:

a plate-like or annular bottom part;

a wall part which is erected along a whole outer peripheral edge of the bottom part and which forms, above the bottom part, an accommodation space for accommodating the extending part; and

a fixing part for detachably fixing a predetermined part of the clip member, the fixing part being formed at a part of the clip fixing jig provided in the accommodation space or being formed in the bottom part or the wall part,

wherein mutually opposing inner surfaces of the wall part are inclined from an upper end of the wall part to a bottom part such that a distance between the mutually opposing inner surfaces is smaller in a direction from the upper end of the wall part toward the bottom part, whereas, in the direction in which the inner surfaces of the wall part oppose each other, movement of the extending part of the clip member is restricted.

2. The clip fixing jig according to claim 1,

wherein said mutually opposing inner surfaces of the wall part that are inclined include a pair of mutually opposing wall parts along long-side outer edges of the bottom part and a pair of mutually opposing wall parts along short-side outer edges of the bottom part.

3. The clip fixing jig according to claim 1,

wherein, when the extending part of the clip member is accommodated in the accommodation space, an upper end face along a whole upper-end length of the wall part comes into contact with the buried part.

4. The clip fixing jig according to claim 2,

wherein, when the extending part of the clip member is accommodated in the accommodation space, an upper end face along a whole upper-end length of the wall part comes into contact with the buried part.

5. The clip fixing jig according to claim 1, further including:

at least the wall part is formed of a magnetic material, wherein the wall part detachably attracts a connection member that is formed of a magnetic material, and

a plurality of clips are connected by the connection member.

6. The clip fixing jig according to claim 1,

wherein said pair of mutually opposing wall parts along the short-side outer edges of the bottom part include through-holes adapted to accommodate clamping screws.

7. The clip fixing jig according to claim 1,

wherein said pair of mutually opposing wall parts along the short-side outer edges of the bottom part are wider than said pair of mutually opposing wall parts along the long-side outer edges of the bottom part.

8. The clip fixing jig according to claim 7,

wherein said pair of mutually opposing wall parts along the short-side outer edges of the bottom part include through-holes adapted to accommodate clamping screws.
