Abstract

A seat device includes a holding member that holds an air tube and is located below a seat cushion. The holding member includes a base wall that defines a holding surface for the air tube, a locking portion that locks air tubes routed along the holding surface on the base wall, and a side wall extending in a routing direction of each of the air tubes.

First claim

The invention claimed is:

1. A holding member configured to hold air tubes for a seat, the holding member comprising:
a base wall that defines a holding surface for the air tubes when the air tubes are held by the holding member;
a locking portion that locks the air tubes routed along the holding surface on the base wall when the air tubes are held by the holding member; and
a side wall extending in a routing direction of each of the air tubes when the air tubes are held by the holding member, wherein
each of the air tubes is routed along the holding surface in a bent state when the air tubes are held by the holding member,
the side wall is located on an inner side of a bent part of each of the air tubes when the air tubes are held by the holding member, and
the holding member further comprises a securing member that secures the air tubes in a bundle to the holding member at the side wall when the air tubes are held by the holding member.

2. The holding member according to claim 1 , wherein the locking portion locks each of the air tubes on the base wall with the air tubes arranged in parallel to one another along the holding surface when the air tubes are held by the holding member.

3. The holding member according to claim 1 , wherein the locking portion includes a tubular portion having a hole that extends in the routing direction of each of the air tubes when the air tubes are held by the holding member.

4. The holding member according to claim 1 , wherein
the locking portion includes tabs protruding from the base wall, and
the tabs are each configured so that each of the air tubes is held between adjacent ones of the tabs when the air tubes are held by the holding member.

5. The holding member according to claim 1 , wherein the locking portion includes a holder that holds each of the air tubes between the locking portion and the base wall by engaging with the base wall when the air tubes are held by the holding member.

6. The holding member according to claim 1 , wherein the base wall is located below a seat cushion with the holding surface facing downward.

7. A holding member configured to hold air tubes for a seat, the holding member comprising:
a base wall that defines a holding surface for the air tubes when the air tubes are held by the holding member, the base wall including
a middle part extending in a width direction of the seat,
a first end extending from a first end of the middle part toward a front side of the seat, and
a second end extending from a second end of the middle part toward a rear side of the seat;

a locking portion that locks the air tubes routed along the holding surface on the base wall when the air tubes are held by the holding member; and
a first side wall disposed at a first corner connecting the first end of the base wall to the middle part, and a second side wall disposed at a second corner connecting the second end of the base wall to the middle part, the first and second side walls extending in a routing direction of each of the air tubes when the air tubes are held by the holding member.

8. The holding member according to claim 7 , wherein the locking portion locks each of the air tubes on the base wall with the air tubes arranged in parallel to one another along the holding surface when the air tubes are held by the holding member.

9. The holding member according to claim 7 , wherein the locking portion includes a tubular portion having a hole that extends in the routing direction of each of the air tubes when the air tubes are held by the holding member.

10. The holding member according to claim 7 , wherein
the locking portion includes tabs protruding from the base wall, and
the tabs are each configured so that each of the air tubes is held between adjacent ones of the tabs when the air tubes are held by the holding member.

11. The holding member according to claim 7 , wherein the locking portion includes a holder that holds each of the air tubes between the locking portion and the base wall by engaging with the base wall when the air tubes are held by the holding member.

12. The holding member according to claim 7 , wherein
each of the air tubes is routed along the holding surface in a bent state when the air tubes are held by the holding member, and
the side wall is located on an inner side of a bent part of each of the air tubes when the air tubes are held by the holding member.

13. The holding member according to claim 7 , wherein the base wall is located below a seat cushion with the holding surface facing downward.
