Abstract

There is provided a cover material fastening clip for attaching a cover material to a cushion material. The clip is provided with a locking portion, a hook portion and a guide portion. The hook portion is provided with an extending portion that extends downward from the locking portion, a first hook piece a second hook portion. The guide portion is formed in the locking portion or the extending portion and is located above the first and second hook pieces. A space between a leading end portion of the first hook piece and the guide portion serves as a first insertion opening with a predetermined gap into which the wire is inserted. A space between a leading end portion of the second hook piece and the guide portion serves as a second insertion opening with a predetermined gap into which the wire is inserted.

Claims

1. A cover material fastening clip for attaching a cover material to a cushion material, comprising:

a locking portion configured to be locked to a locking end member disposed at an edge of the cover material;

a hook portion configured to locked to a wire disposed in a groove of the cushion material; and

a guide portion configured to guide the wire to the hook portion,

wherein the hook portion is formed below the locking portion and the hook portion is provided with an extending portion that extends downward from the locking portion, a first hook piece that extends laterally from a leading end portion of the extending portion in an extending direction thereof, and a second hook portion that extends to an opposite side of the first hook piece,

wherein the guide portion is formed in the locking portion or the extending portion and is located above the first hook piece and the second hook piece,

wherein a space between a leading end portion of the first hook piece and the guide portion serves as a first insertion opening with a predetermined gap into which the wire is inserted, and

wherein a space between a leading end portion of the second hook piece and the guide portion serves as a second insertion opening with a predetermined gap into which the wire is inserted.

2. The cover material fastening clip according to claim 1,

wherein a portion of the guide portion facing the first insertion opening forms a first upper guide surface,

wherein a portion of the first hook piece facing the first insertion opening forms a first lower guide surface,

wherein a gap between the first upper guide surface and the first lower guide surface is gradually narrowed toward the first insertion opening,

wherein a portion of the guide portion facing the second insertion opening forms a second upper guide surface,

wherein a portion of the second hook piece facing the second insertion opening forms a second lower guide surface, and

wherein a gap between the second upper guide surface and the second lower guide surface is gradually narrowed toward the second insertion opening.

3. The cover material fastening clip according to claim 2,

wherein an inclined surface inclined upwardly toward a lateral side from the extending portion is formed at an end portion of the first hook piece in the extending direction of the extending portion, and

wherein an inclined surface inclined upwardly toward a lateral side from the extending portion is formed at an end portion of the second hook piece in the extending direction of the extending portion.

4. The cover material fastening clip according to claim 2,

wherein the first upper guide surface and the first lower guide surface are arranged such that extension lines thereof intersect each other at an angle of 80°

to 120°

, and

wherein the second upper guide surface and the second lower guide surface are arranged such that extension lines thereof intersect each other at an angle of 80°

to 120°

.

5. The cover material fastening clip according to claim 1, wherein the first hook piece and the second hook piece and the guide portion are formed to be symmetric with respect to a center line of the extending portion in the extending direction thereof.

6. The cover material fastening clip according to claim 1, wherein the first hook piece and the second hook piece are arranged so as to lock a jig for removing the first hook piece and the second hook piece from the wire.

7. The cover material fastening clip according to claim 6, wherein a holding space for holding the wire is formed in the first hook piece and the second hook piece, and a jig groove to which the jig is fitted is formed on a bottom portion of the holding space.
