Abstract

Provided is vehicle seat with a seat cushion and a seat back, the vehicle seat comprising: a duct disposed astride the seat cushion and the seat back, and configured to connect an air passage and a blower, the air passage being formed in the seat cushion and the seat back; and a side frame cover configured to cover part of the duct. The duct includes a first duct member and a second duct member connected to the first duct member. The side frame cover is configured to cover at least part of a first connected section that is a section at which the first duct member and the second duct member are connected.

First claim

The invention claimed is:

1. A vehicle seat with a seat cushion and a seat back, the vehicle seat comprising:
a duct disposed astride the seat cushion and the seat back, and configured to connect an air passage and a blower, the air passage being formed in at least one of the seat cushion and the seat back, the duct comprising:
a first duct member, and
a second duct member that is connected to the first duct member;

a cover member configured to cover part of the duct;
left and right cushion side frames which constitute left and right frames of the seat cushion; and
a rear frame by which rear portions of the left and right cushion side frames are connected,
wherein the cover member is configured to cover at least part of a first connected section that is a section at which the first duct member and the second duct member are connected,
wherein the first duct member comprises:
a first engageable portion, and
a second engageable portion that are provided in the first connected section,

wherein the second duct member comprises:
a third engageable portion that is engageable with the first engageable portion, and
a fourth engageable portion that is engageable with the second engageable portion,
wherein the second engageable portion and the fourth engageable portion are provided at a right side surface or a left side surface of the first connected section, wherein the cover member is further configured to cover the first engageable portion and the third engageable portion, but not to cover the second engageable portion and the fourth engageable portion, and
wherein the duct is laid across a rear side of the rear frame and extends from the seat cushion toward the seat back.

2. The vehicle seat according to claim 1 , wherein the first connected section is located in a position shifted closer to the left or right cushion side frame than to a center of the seat cushion in a lateral direction, and
wherein the first engageable portion and the third engageable portion are provided at a side surface of the first connected section that is more distant than the second engageable portion and the fourth engageable portion from the center of the seat cushion in the lateral direction.

3. The vehicle seat according to claim 2 , wherein the first engageable portion and the third engageable portion are located, in the lateral direction, closer to a door for getting in and out of a rear side of the vehicle seat than the second engageable portion and the fourth engageable portion.

4. The vehicle seat according to claim 1 , wherein the first engageable portion and the second engageable portion are projections having outwardly protruding shapes, and the third engageable portion and the fourth engageable portion are through holes with which the projections are engageable.

5. The vehicle seat according to claim 4 , wherein the projections include barb portions that extend opposite to a direction in which the first duct member is connected to the second duct member.

6. The vehicle seat according to claim 1 , wherein the second duct member is connected to a rear end of the first duct member and extends upward,
wherein the duct includes a third duct member disposed at the seat back and connected to an upper end of the second duct member, and
wherein the cover member is configured to cover at least part of a second connected section that is a section at which the second duct member and the third duct member are connected.

7. The vehicle seat according to claim 1 , wherein one of the seat cushion and the seat back has a first air passage and a second air passage, and
wherein the duct includes a first duct portion connecting to the first air passage, and a second duct portion branching off from the first duct portion and connecting to the second air passage.

8. A vehicle seat with a seat cushion and a seat back, the vehicle seat comprising:
(a) a duct, disposed astride the seat cushion and the seat back, and configured to connect an air passage and a blower, the air passage being formed in at least one of the seat cushion and the seat back, the duct comprising:
a first duct member,
a second duct member that is connected to a rear end of the first duct member and extends upward,
a third duct member that is disposed at the seat back and is connected to an upper end of the second duct member;

(b) left and right back side frames which constitute left and right frames of the seat back;
(c) a cover member configured to cover: part of the duct including at least part of a first connected section that is a section at which the first duct member and the second duct member are connected, and at least part of a second connected section that is a section at which the second duct member and the third duct member are connected, the cover member comprising:
a plate-shaped rear cover attached to the left and right back side frames and bridging the left and right back side frames, the rear cover being configured to cover a rear side of the second connected section.
