Abstract
Official abstract text for this publication.
A vehicle seat includes a pad configured to support a body of a seated occupant. The pad has a transverse air passage extending in a direction along a back surface of the pad and a plurality of longitudinal air passages each having one end connecting with the transverse air passage and the other end open to a front surface of the pad. The transverse air passage has a first transverse air passage connecting an air introduction hole from a fan or an air discharge hole to the fan and the longitudinal air passage directly with each other, and a second transverse air passage connecting the air introduction hole or the air discharge hole and the longitudinal air passage with each other via a resistant body having a resistance against an air flow.
First claim
Opening claim text (preview).
What is claimed is: 1. A vehicle seat comprising: a pad configured to support a body of a seated occupant, wherein the pad has a transverse air passage extending in a direction along a back surface of the pad and a plurality of longitudinal air passages each having one end connecting with the transverse air passage and the other end open to a front surface of the pad, and the transverse air passage has a first transverse air passage connecting an air introduction hole from a fan and at least one of the plurality of longitudinal air passages directly with each other, and a second transverse air passage connecting the air introduction hole and at least another one of the plurality of longitudinal air passages with each other via a resistant body having a resistance against an air flow that is interposed between the air introduction hole and the at least another one of plurality of longitudinal air passages, wherein the resistant body is a three-dimensional fabric, the first transverse air passage and the second transverse air passage are defined by a recess shaped groove provided on the back surface side of the pad and a non-permeable planar member stretched on the back surface side of the pad, and the three-dimensional fabric is disposed in abutment with the non-permeable planar member in the second transverse air passage. 2. The vehicle seat according to claim 1 , wherein the three-dimensional fabric has a size to cover the second transverse air passage and at least part of the first transverse air passage and is placed on the non-permeable planar member, and the three-dimensional fabric is thermally bonded to the non-permeable planar member at a portion corresponding to the first transverse air passage. 3. The vehicle seat according to claim 1 , wherein when air is introduced into the second transverse air passage, the air flows from the air introduction hole to the at least another one of the plurality of longitudinal passages through the resistant body. 4. A vehicle seat comprising: a pad configured to support a body of a seated occupant, wherein the pad has a transverse air passage extending in a direction along a back surface of the pad and a plurality of longitudinal air passages each having one end connecting with the transverse air passage and the other end open to a front surface of the pad, and the transverse air passage has a first transverse air passage connecting an air introduction hole from a fan and at least one of the plurality of longitudinal air passages directly with each other, and a second transverse air passage connecting the air introduction hole and at least another one of the plurality of longitudinal air passages with each other via a resistant body having a resistance against an air flow, wherein the resistant body is a three-dimensional fabric, the first transverse air passage and the second transverse air passage are defined by a recess shaped groove provided on the back surface side of the pad and a non-permeable planar member stretched on the back surface side of the pad, and the three-dimensional fabric is disposed in abutment with the non-permeable planar member in the second transverse air passage.
