Abstract

A cover material attachment includes: a base to be installed in a groove of a cushion material; a first support and a second support that are provided upright on the base toward an opening of the groove, and are opposed to each other in a width direction of the groove; a first protrusion and a second protrusion that respectively protrude from the first and second supports in respective directions that bring the first and second protrusions closer to each other, and are to be engaged with an engaging member; and a first frame and a second frame that are provided upright on the base toward the opening of the groove and are opposed to each other in the width direction of the groove. The first and second frames each include a guide configured to guide the engaging member to a space between the first protrusion and the second protrusion.

First claim

What is claimed is:

1 . A cover material attachment that is configured to be installed in a groove provided in a cushion material of a seat and is configured to be engaged with an engaging member attached to a cover material, the cover material attachment comprising:
a base configured to be installed in the groove of the cushion material; a first support and a second support that are provided upright from the base toward an opening of the groove, and are opposed to each other in a width direction of the groove; a first protrusion and a second protrusion that respectively protrude from the first support and the second support in respective directions that bring the first protrusion and the second protrusion closer to each other, the first protrusion and the second protrusion being configured to be engaged with the engaging member; and a first frame and a second frame that are provided upright from the base toward the opening of the groove and are opposed to each other in the width direction of the groove, the first frame and the second frame being configured to guide the engaging member to a space between the first protrusion and the second protrusion, wherein the first frame and the second frame are respectively configured to undergo elastic deformation independently of the first support and the second support when a load is applied on a side of the groove on which the opening is provided.

2 . The cover material attachment according to claim 1 , wherein the first frame and the second frame each comprise:
a pair of legs provided upright on the base, and a connecting portion that couples respective end portions of the pair of legs.

3 . The cover material attachment according to claim 2 , wherein:
the first support is disposed between the pair of legs of the first frame, and the second support is disposed between the pair of legs of the second frame.

4 . The cover material attachment according to claim 2 , wherein:
the first support has a space that is continuous from between the first support and each of the pair of legs of the first frame to between the first support and the connecting portion of the first frame, and the second support has a space that is continuous from between the second support and each of the pair of legs of the second frame to between the second support and the connecting portion of the second frame.

5 . The cover material attachment according to claim 2 , wherein the pair of legs of the first frame has a guide surface and the pair of legs of the second frame has a guide surface, the guide surfaces being inclined with respect to a depth direction of the groove in such a manner as to face a side where the guide surfaces oppose each other and the side of the groove on which the opening is provided.

6 . The cover material attachment according to claim 5 , wherein:
the first protrusion has an auxiliary guide surface disposed in a plane identical to a plane in which the guide surface of the first frame is disposed in a no-load state, and the second protrusion has an auxiliary guide surface disposed in a plane identical to a plane in which the guide surface of the second frame is disposed in the no-load state.

7 . The cover material attachment according to claim 5 , wherein:
the first support has an intermediate guide disposed in a plane identical to a plane in which the guide surface of the first frame is disposed in a no-load state, and the second support has an intermediate guide disposed in a plane identical to a plane in which the guide surface of the second frame is disposed in the no-load state.

8 . The cover material attachment according to claim 1 , wherein the first frame and the second frame each comprise:
a riser portion that extends from the base, a guide that extends from the riser portion in a direction inclined with respect to a depth direction of the groove, the guide being configured to guide the engaging member to the space, and a fixing portion that extends from the guide toward an outer side of the groove in the width direction and is configured to be fixed to the cushion material.
