It is provided a seat pad having excellent comfort in seating with improved air permeability and cushion durability in a seat pad of the vehicle seat. The seat pad includes an air permeable member having a ventilation n function with an outside. The seat pad is integrally foam molded using a foamed resin material in a state where the air permeable member is introduced. The seat pad has a surface of the air permeable member projecting with respect to a surface of the seat pad located at a closest position to the air permeable member.

Seat pad and method for manufacturing seat pad

Providing a seat pad that can provide good sitting comfortability with bonding between a ventilation member and an expanded resin foam included in the seat pad ensured. A seat padincluding a ventilation memberhaving a function that lets air through to/from an outside, the seat padbeing formed by integral expansion molding of an expandable resin material M with the ventilation memberintroduced therein, includes a covering memberthat covers at least a part of the ventilation memberat an interface between the ventilation memberand the expandable resin material M, and the covering memberincludes an impregnation inhibiting material having a function that inhibits infiltration of the expandable resin material M, the function being at least higher than that of the ventilation member

Seat pad

A tubular lower mold partitioning wall is erected on a lower mold, and a three-dimensional mesh-like body is disposed with a part of a side face exposed with respect to the lower mold partitioning wall. When a pad main body is molded by foaming a liquid raw material, the mesh-like body is penetrated through the pad main body in a thickness direction. Since the mesh-like body is disposed with a part of the side face exposed with respect to the lower mold partitioning wall, the liquid raw material is hardened between the fibers on the side face of the mesh-like body, and the side face is attached to the pad main body. Therefore, it is possible that the mesh-like body is not easily displaced with respect to the pad main body while suppressing a sweaty feeling.

Method of manufacture of seat pad

To make it possible to provide an acoustic device in a headrest device such that a standard of a shock is satisfied and the performance of the acoustic device can be efficiently exhibited. In the headrest device, a shock resistant surface is formed in a core material of a headrest main body, an opening is formed in the shock resistant surface, and a non-contact type acoustic microphone is disposed on the inner side of the opening.

Headrest device and sound collecting device

A three-dimensional mesh-like body is disposed on a molding face of a lower mold onto which a liquid raw material of flexible foam is poured. An upper mold is laid over the lower mold to form a cavity, a projection projected on the upper mold toward the cavity is contacted with the three-dimensional mesh-like body, and the three-dimensional mesh-like body is fixed. The three-dimensional mesh-like body is attached and fixed to a front surface of a pad main body, so that the three-dimensional mesh-like body can be prevented from being displaced with respect to the pad main body. Moreover, the position of the three-dimensional mesh-like body can be prevented from being displaced in the process of foaming the liquid raw material because of the projection, and a vent hole can be formed on the pad main body. As a result, a sweaty feeling can be suppressed.

There is provided a seat padincluding a pad bodyformed of a foam resin molding and a breathable cushion bodyformed of a three-dimensional net structure made of linear bodies and provided in a pad surface side of the pad body. In the pad body, pulling-in groovesfor pulling in a skin materialare provided on a pad surface, wiresare embedded along the pulling-in grooves, and locking holesexposing part of the wiresare provided. The locking holesare provided so as to pierce the pad to a pad reverse side and the breathable cushion bodyis provided in a state where side surfaces thereof abut on the pulling-in groovesso as to communicate thereto.

To provide a seat with ventilative property, which can eliminate or minimize the possibility of its being permanently deformed and settled into an unrecoverable deformed state. In the seat with ventilative property, left and right three-dimensional network cushion elements are provided in a forwardly-facing region of a seat cushion of the seat, in a manner independent of each other, such that the left and right three-dimensional network cushion elements are respectively situated at: one location on which a left thigh portion of a seat occupant is to be contacted; and the other location on which a right thigh portion of the seat occupant is to be contacted. This arrangement can almost completely prevent a direct application of a weight of the seat occupant to the two three-dimensional network cushion elements. Therefore, the present invention has the effect that a permanent downward settling of the seat cushion SC can be prevented, so that a short life of the seat due to such permanent settling may be substantially avoided.

Seat with ventilative property

A headrest including: a trim cover element formed in a three-dimensional bag-like configuration, a fiber assembly; and a foam padding. The fiber assembly and foam padding are both provided within the trim cover element in such a manner that the fiber assembly is secured to and positioned on a front surface side of the trim cover element, whereas the foam padding is positioned on a rear surface side of the fiber assembly. The foam padding has been created by a foaming process so as to be integral with the trim cover element and fiber assembly.

Headrest

In a seat with ventilation property, at least one three-dimensional network cushion element is provided in a foam padding(s) of the seat at at least one point on which at least one body portion of a seat occupant is to be substantially contacted. The three-dimensional network cushion element is formed by a plurality of fibers, each being composed of a core portion and a sheath portion covering the core portion, such that all the fibers are bonded with one another at the respective sheath portions thereof. Preferably, each of the fibers may be an helical fiber of eccentric core type wherein the core portion is eccentrically positioned in the sheath portion. Further, the three-dimensional network cushion element(s) may be arranged in the foam padding so as to prevent intensive exertion of a load from the seat occupant's body portion(s) upon the three-dimensional network cushion element(s).
