Abstract

A fixing unit includes: an attachment member attached to a seat body; an engaging member engaged with an opening provided to the seat body; and a string member connecting the attachment member and the engaging member, the string member being engaged with a cover. The engaging member includes: a body to which the string member is attached; a first contact portion provided to the body to be in contact with a first periphery of the opening; and an insert portion provided on the body at a position spaced apart from the first contact portion, the insert portion being inserted into the opening. The insert portion includes a first restricting portion to be in contact with a second periphery of the opening opposite the first periphery to restrict the insert portion from being detached from the opening.

First claim

The invention claimed is:

1. A fixing unit that is used for a seat comprising a seat body and a cover that covers the seat body, the fixing unit being used for fixing the cover to the seat body, the fixing unit comprising:
an attachment member attached to the seat body;
an engaging member engaged with an opening provided to the seat body; and
a string member that connects the attachment member and the engaging member and is engaged with the cover, wherein
the engaging member comprises:
a body to which the string member is attached;
a first contact portion provided to the body to be in contact with a first periphery of the opening; and
an insert portion provided to the body being spaced apart from the first contact portion and provided with a first restricting portion,
wherein, the insert portion has elasticity, and
the insert portion is elastically deformed when inserted into the opening and once inserted, the first restricting portion is in contact with a second periphery of the opening opposite the first periphery and the first restricting portion retains the insert portion in the opening.

2. The fixing unit according to claim 1 , wherein
the insert portion comprises:
a first extension extending in a direction perpendicular to a central axis of the body;
a bent portion that is bent from an end of the first extension away from the first contact portion; and
a second extension extending from the bent portion towards the body, and
the first restricting portion is provided at an end of the second extension.

3. The fixing unit according to claim 1 , further comprising:
a second restricting portion located at a position corresponding to the second periphery, the second restricting portion being in contact with the seat body to restrict the insert portion from being sunk into the opening once the insert portion is inserted into the opening.

4. The fixing unit according to claim 1 , wherein
the seat body comprises a plate body provided thereon with the opening, and
the fixing unit comprises a second contact portion extending from the first contact portion in a direction from the insert portion to the first contact portion, the second contact portion in contact with a side of the plate body opposite a side of the plate body at which the body is located once the insert portion is inserted into the opening.

5. The fixing unit according to claim 1 , further comprising:
a third contact portion extending from the first contact portion in a direction orthogonal to both a central axis of the body and a direction perpendicular to a plane of the opening, the third contact portion being in contact with a part of the seat body outside the opening.

6. The fixing unit according to claim 1 , wherein the seat body comprises a plate body provided thereon with the opening, further comprising:
a fourth contact portion extending from the first contact portion in a direction from the insert portion to the first contact portion, the fourth contact portion being in contact with a part of the plate body outside the opening.

7. A seat, comprising:
a seat body;
a cover covering the seat body; and
the fixing unit according to claim 1 ,
wherein the seat body comprises the opening in which the engaging member is engaged, and
the opening is divided by a dividing portion into:
a first opening including the first periphery; and
a second opening including the second periphery.

8. A cover fixing method that is used for a seat comprising a seat body and a cover that covers the seat body, the cover fixing method being used for fixing the cover to the seat body, the method comprising:
an attaching step for attaching an attachment member of a fixing unit to the seat body and engaging the cover with a string member connected to the attachment member; and
an engaging step for engaging an engaging member to an opening provided to the seat body, the engaging member being provided on a side opposite the attachment member with the string member being interposed therebetween, wherein
in the engaging step a contact portion provided on the engaging member is brought into contact with a first periphery of the opening,
the engaging member is rotated around the contact portion to insert an insert portion into the opening, and
a part of the insert portion is brought into contact with a second periphery of the opening opposite the first periphery to retain the insert portion in the opening.

9. A fixing unit that is configured to fix a cover to a seat, the fixing unit comprising:
an attachment member having a hook;
a string member that connects the attachment member and an engaging member;
the engaging member comprising:
a body to which the string member is attached;
an insert portion provided to the body, wherein the insert portion comprises:
a first extension extending in a direction perpendicular to a central axis of the body;
a bent portion that is bent from an end of the first extension away from an end of the body attached to the string member;
a second extension extending from the bent portion towards the body; and
a first restricting portion provided at an end of the second extension; and

a first contact portion, a second contact portion, and a third contact portion, wherein the first contact portion, the second contact portion, and the third contact portion are provided to the body and are spaced apart from the insert portion.

10. The fixing unit according to claim 9 , further comprising:
a second restricting portion located near an end of the body that is opposite the first contact portion.

11. The fixing unit according to claim 9 , wherein the second contact portion extends from the first contact portion in a direction from the insert portion to the first contact portion.

12. The fixing unit according to claim 11 , further comprising:
a bridge portion that extends from an end of the second contact portion near the insert portion toward the insert portion.

13. The fixing unit according to claim 9 , wherein the third contact portion extends from the first contact portion in a direction orthogonal to both the central axis of the body and the first extension.
