Cover material fastening clip
A cover-material fastening clip includes a locking portion having a guide piece and a hook which includes an extension portion and a distal end portion. The guide piece extends includes a bent portion bent and extended toward the distal end portion. An insertion opening having a predetermined gap and allowing a wire to be inserted therethrough is positioned between the bent portion and the distal end portion. A distal end portion of the guide piece extending from the bent portion is an elastic piece portion being elastically deformed to be spaced from the distal end portion and to widen the insertion opening. In a part of the locking portion, which is located within a range, in which the elastic piece portion can be elastically deformed and thus moved, an escape space is provided to allow a distal end of the elastic piece portion to be positioned therein.

wherein the locking portion comprises a pair of locking claws and a locking claw base portion connected to base end portions of the locking claws, wherein the guide piece is provided on one of the pair of locking claws, wherein the hook is provided on a lower surface of the locking claw base portion opposite to an upper surface thereof, on which the locking claws are provided, wherein the escape space is formed by a groove portion provided at a location on the lower surface of the locking claw base portion closer to the guide piece than the hook.
2. A cover-material fastening clip for connecting a cover material with a cushion material, comprising a locking portion configured to be locked on a locking end member provided on an end edge of the cover material, and a hook configured to be locked on a to-be-locked member installed in the cushion material,
wherein the hook is provided below the locking portion and the hook comprises an extension portion extending downward from the locking portion and a distal end portion extending laterally from a distal end of the extension portion,
wherein the locking portion is provided with a guide piece,
wherein the guide piece extends downward from the locking portion and comprises a bent portion in the middle thereof to be bent and extended toward the distal end portion of the hook, wherein the guide piece is positioned such that an insertion opening having a predetermined gap and configured to allow the to-be-locked member to be inserted therethrough is formed between the bent portion and the distal end portion,
wherein a distal end portion of the guide piece extending from the bent portion is an elastic piece portion capable of being elastically deformed to be spaced from the distal end portion of the hook and thus to widen the insertion opening, wherein in a part of the locking portion, which is located within a range, in which the elastic piece portion can be elastically deformed and thus moved, an escape space is provided to allow the elastic piece portion to be positioned therein,
wherein the locking portion comprises a pair of locking claws and a locking claw base portion connected to base end portions of the locking claws, wherein the guide piece is provided on one of the pair of locking claws, wherein the hook is provided on a lower surface of the locking claw base portion opposite to an upper surface thereof, on which the locking claws are provided, wherein the escape space is formed by a through-hole provided at a location on the locking claw base portion closer to the guide piece than the hook so as to extend therethrough from the upper surface to the lower surface.
3. The cover-material fastening clip according to claim 2 , wherein a reinforcing plate is provided on the extension portion of the hook.
4. A cover-material fastening clip for connecting a cover material with a cushion material, comprising a locking portion configured to be locked on a locking end member provided on an end edge of the cover material, and a hook configured to be locked on a to-be-locked member installed in the cushion material,
wherein the hook is provided below the locking portion and the hook comprises an extension portion extending downward from the locking portion and a distal end portion extending laterally from a distal end of the extension portion,
wherein the locking portion is provided with a guide piece,
wherein the guide piece extends downward from the locking portion and comprises a bent portion in the middle thereof to be bent and extended toward the distal end portion of the hook, wherein the guide piece is positioned such that an insertion opening having a predetermined gap and configured to allow the to-be-locked member to be inserted therethrough is formed between the bent portion and the distal end portion,
wherein a distal end portion of the guide piece extending from the bent portion is an elastic piece portion capable of being elastically deformed to be spaced from the distal end portion of the hook and thus to widen the insertion opening, wherein in a part of the locking portion, which is located within a range, in which the elastic piece portion can be elastically deformed and thus moved, an escape space is provided to allow the elastic piece portion to be positioned therein,
