Abstract

A vehicle seat includes a seat frame including a pan frame (12), a blower, and a bracket (50) configured to attach the blower to the pan frame (12). The bracket (50) is provided with a first engagement portion (110) protruding toward the pan frame (12), and the pan frame (12) is provided with a first engagement hole (12A) in which the first engagement portion (110) is engageable. The first engagement portion (110) includes a first stopper portion (112) configured to be locked to the pan frame (12) when the first engagement portion (110) is engaged in the first engagement hole (12A), and a first elastically deformable portion (113) configured to deform elastically to allow the first stopper portion (112) to pass through the first engagement hole (12A) when the first engagement portion (110) is inserted into the first engagement hole (12A).

First claim

The invention claimed is:

1. A vehicle seat comprising:
a seat frame including a plate portion;
a blower having an inlet opening; and
a bracket configured to attach the blower to the plate portion,
wherein one of the bracket and the plate portion is provided with a first engagement portion protruding toward the other one of the bracket or the plate portion,
wherein a first engagement hole in which the first engagement portion is engageable is provided at the other one of the bracket or the plate portion,
wherein the bracket comprises:
a base wall having a first through opening and two or more second through openings, the first through opening being formed in a position corresponding to the inlet opening of the blower, the second through openings being formed around the first through opening, and

wherein the first engagement portion is provided at a rear side of the first through opening, and at least one of the second through openings is located at a front side of the first through opening.

2. The vehicle seat according to claim 1 , further comprising:
an attachment member that comprises the first engagement portion and a second engagement portion, the second engagement portion protruding toward the one of the bracket and the plate portion,
wherein the first engagement portion comprises:
a first stopper portion configured to be locked to the other one of the bracket or the plate portion when the first engagement portion is engaged in the first engagement hole, and
a first elastically deformable portion configured to deform elastically to allow the first stopper portion to pass through the first engagement hole when the first engagement portion is inserted into the first engagement hole,

wherein the one of the bracket or the plate portion has a second engagement hole in which the second engagement portion is engageable, and
wherein the first engagement portion is provided on the one of the bracket or the plate portion when the second engagement portion is engaged in the second engagement hole to attach the attachment member to the one of the bracket or the plate portion.

3. The vehicle seat according to claim 2 , wherein the second engagement portion comprises:
a second stopper portion configured to be locked to the one of the bracket or the plate portion when the second engagement portion is engaged in the second engagement hole; and
a second elastically deformable portion configured to deform elastically to allow the second stopper portion to pass through the second engagement hole when the second engagement portion is inserted into the second engagement hole.

4. The vehicle seat according to claim 2 , wherein the second engagement hole is a through hole formed in the bracket, and
wherein the blower has a third engagement hole engageable with the second engagement portion having been engaged in the second engagement hole.

5. The vehicle seat according to claim 4 , wherein the bracket has three projections protruding toward the blower, and
wherein the second engagement hole is formed in each of the projections.

6. The vehicle seat according to claim 1 , wherein the first engagement portion is formed in one-piece with the one of the bracket or the plate portion.

7. The vehicle seat according to claim 1 , wherein the first engagement portion is provided on the plate portion, and the first engagement hole is a through hole formed in the bracket, and
wherein the blower has a fourth engagement hole engageable with the first engagement portion having been engaged in the first engagement hole.

8. The vehicle seat according to claim 7 , wherein the bracket has three projections protruding toward the blower, and
wherein the first engagement hole is formed in each of the projections.

9. The vehicle seat according to claim 1 , wherein the plate portion has a plurality of attachment holes for attachment of members, and
wherein one of the attachment holes is used as the first engagement hole.

10. The vehicle seat according to claim 2 , wherein the plate portion has a plurality of attachment holes for attachment of members, and
wherein one of the attachment holes is used as the second engagement hole.

11. The vehicle seat according to claim 1 ,
wherein the seat frame comprises:
frameworks of a seat cushion and a seat back,

wherein the seat cushion includes a first air flow passage,
wherein the seat back includes a second air flow passage,
wherein the vehicle seat further comprises a duct connecting the first air flow passage and the second air flow passage to the blower,
wherein the duct includes a connecting tubular portion disposed to bridge between the seat cushion and the seat back, and
wherein the vehicle seat further comprises:
a cover member, the cover member being configured to cover at least a part of the connecting tubular portion and to be fixed to the seat frame so that a position of the connecting tubular portion is restricted by the cover member.

12. The vehicle seat according to claim 11 , wherein the connecting tubular portion includes a flexible portion having flexibility, and
wherein the cover member is provided to cover at least a part of the flexible portion.

13. The vehicle seat according to claim 11 , wherein the cover member comprises a protruding portion, the protruding portion being configured to protrude inward toward the connecting tubular portion that is disposed in an inner space of the cover member, so that the protruding portion contacts the connecting tubular portion.

14. The vehicle seat according to claim 13 , wherein the protruding portion is provided on each right and left side of the connecting tubular portion so as to sandwich the connecting tubular portion therebetween.

15. The vehicle seat according to claim 14 , wherein the connecting tubular portion includes a bellows portion comprises crest portions and root portions that are alternately formed one after another, and
wherein the protruding portion is provided to enter one of the root portions.

16. The vehicle seat according to claim 11 , wherein one of the cover member or the connecting tubular portion has protruding portions located on right and left sides of the connecting tubular portion and configured to protrude toward the other one of the cover member or the connecting tubular portion, and
wherein the other one of the cover member or the connecting tubular portion has recess portions in which corresponding protruding portion are engageable.

17. The vehicle seat according to claim 16 , wherein each of the recess portions has a groove-shape extending in a direction in which the duct extends.

18. The vehicle seat according to claim 11 , wherein the cover member comprises a first wall disposed such that the connecting tubular portion is sandwiched between the first wall and the seat frame, and a pair of second walls extending from right and left ends of the first wall toward the seat frame.
