Abstract

There is provided a skin-material fixing clip for connecting a skin material with a cushion material and provided with a locking section and a hook. The hook is provided with an extension portion extending downward from the locking section and a claw-shaped portion extending laterally from a distal end of the extension portion. The locking section is provided with a wire guide piece. A groove portion surrounded by the claw-shaped portion and the extension portion defines a wire holding space. Parts of the wire guide piece and the claw-shaped portion facing the wire insertion opening defines guide surfaces. The distal end portion of the wire guide piece and the distal end portion of the claw-shaped portion are provided to be spaced from each other along a direction parallel to an extending direction of the groove portion.

Claims

1. A skin-material fixing clip for connecting a skin material with a cushion material and provided with a locking section configured to be locked on a locking end material provided on an end edge of the skin material, and a hook configured to be locked on a wire installed in the cushion material,

wherein the hook is provided below the locking section and the hook is provided with an extension portion extending downward from the locking section and a claw-shaped portion extending laterally from a distal end of the extension portion,

wherein the locking section is provided with a wire guide piece,

wherein the wire guide piece extends downward from the locking section and then is provided with a bent portion in the middle thereof to be bent and extended toward a distal end portion of the claw-shaped portion of the hook, wherein a distal end portion of the wire guide piece is positioned so that a wire insertion opening having a predetermined gap and configured to allow the wire to be inserted therethrough is formed between the distal end portion and the distal end portion of the claw-shaped portion,

wherein a groove portion surrounded by the claw-shaped portion and the extension portion defines a wire holding space extending along an inserting direction of the wire,

wherein parts of the wire guide piece and the claw-shaped portion facing the wire insertion opening defines guide surfaces, respectively, and

wherein the distal end portion of the wire guide piece is located on one side of a center line of the clip and the distal end portion of the claw-shaped portion is located on an opposite side of the center line and the center line extends downward from the locking section.

2. The skin-material fixing clip according to claim 1, wherein an elastic piece portion, which extends from the bent portion to the distal end portion of the wire guide piece is located on the one side of the center line of the clip, and the distal end portion of the claw-shaped portion is located on the opposite side of the center line, wherein the guide surface of the wire guide piece is parallel to an extending direction of the groove portion.

3. The skin-material fixing clip according to claim 2, wherein the wire guide piece is formed so that a thickness of the elastic piece portion in a direction along the guide surface is thinner than a thickness of a part of a base portion, which extends from the locking section to the bent portion, in a direction along the guide surface.

4. The skin-material fixing clip according to claim 1, wherein the distal end portion of the claw-shaped portion of the hook is formed to have a first end portion protruding toward the locking section and a second end portion opposing the guide surface of the wire guide piece and protruding toward the locking section.

5. The skin-material fixing clip according to claim 1, wherein a distance between the guide surfaces, respectively, of the wire guide piece and the claw-shaped portion is gradually narrowed toward the wire insertion opening.

6. The skin-material fixing clip according to claim 1, wherein the distal end portion of the wire guide piece is positioned above the distal end portion of the claw-shaped portion.

7. The skin-material fixing clip according to claim 6, wherein the distal end portion of the wire guide piece is positioned closer to the extension portion compared to the distal end portion of the claw-shaped portion.

8. The skin-material fixing clip according to claim 7, wherein the wire guide piece extends in a direction away from the extension portion as the wire guide piece goes downward from the locking section, and then is provided with the bent portion to be bent and extended toward the distal end portion of the claw-shaped portion of the hook.

9. The skin-material fixing clip according to claim 1, wherein the hook has a flange portion extending in a direction opposite to an extending direction of the claw-shaped portion of the extension portion, wherein the flange portion has a distal end formed to be inclined in a direction away from the locking section, wherein a jig receiving portion configured to allow a jig for separating the hook from the wire to be locked therein, is provided on the distal end of the flange portion.

10. The skin-material fixing clip according to claim 1, wherein the locking section, the hook and the wire guide piece are integrated and made from synthetic resin.

11. The skin-material fixing clip according to claim 1, wherein the wire guide piece is configured to be elastically deformed so that the distal end portion of the wire guide piece approaches a base portion of the locking section when the wire enters to the wire holding space.

12. The skin-material fixing clip according to claim 1, wherein the wire guide piece extends toward a distal end portion of the claw-shaped portion of the hook to the extent that the wire guide piece is positioned above the distal end portion of the claw-shaped portion of the hook.
