AI Technical Summary

Benefits of technology

The invention is about a seat apparatus that can direct temperature controlled air to an individual seated on the seat. This is done by including a filling member with a groove in the sitting portion of the seat, and a cover member that covers the filling member. An air vent is provided that communicates with the groove, and a temperature controlled air producing device produces air that is directed through the air vent and into the groove to provide temperature controlled air to the individual. Additionally, the invention includes a method of blowing temperature controlled air to an individual based on the pressure distribution of the individual on the seat. The technical effects of this invention include improved comfort and well-being for individuals seated on the seat, as well as improved air conditioning efficiency and control.

Problems solved by technology

This known type of seat apparatus suffers from the disadvantage that it is difficult to efficiently send the controlled air to selected desirable parts of the seat for the seated individual and so the seat apparatus is not as comfortable as it might otherwise be.
In addition, this seat apparatus contains both spring members and metal meshes so that the seat apparatus has a complicated structure and is relatively expensive to produce.

Embodiment Construction

[0014]With reference initially to FIG. 1, the seat apparatus 10 of the present invention is illustrated in the context of a vehicle seat apparatus that is adapted to be connected to a vehicle floor. The seat apparatus 10 includes a seat cushion 20, a seat back 40 extending upwardly from the rear portion of the seat cushion 20, and a head rest 50 that is connected to the seat back 40 through a pair of stays 51, only one of which is shown in FIG. 1. The seat cushion 20 and the seat back 40 constitute sitting portions of the seat apparatus.

[0015]The seat cushion 20 includes a urethane member 21 constituting a filling member and S-shaped springs 22 which support the urethane member 21. The urethane member 21 has an air vent 23 that extends upwardly from the lower side of the cushion 20. In the disclosed embodiment, the air vent 23 is generally centrally located in the seat cushion 20 as seen in FIG. 4 and extends from the bottom portion of the urethane member 21 towards the upper portio...

Abstract

A seat apparatus includes a seat cushion, a seat back associated with the seat cushion, an air vent extending from the bottom side of the cushion towards the sitting side of the cushion, and an air producing device which blows air, preferably temperature controlled air, to the air vent and to a groove facing the sitting side of the cushion. The seat apparatus is thus able to distribute air, preferably temperature controlled air, to the seated individual.

Description

FIELD OF THE INVENTION[0001]This invention generally relates to a seat apparatus. More particularly, the present invention pertains to a seat apparatus for a vehicle or other use that is provided with an air flow producing mechanism.BACKGROUND OF THE INVENTION[0002]A known type of seat apparatus is disclosed in Japanese Patent Laid-Open Publication No. Hei 3-151912 published on Jun. 28, 1991. The disclosed seat apparatus includes a seat cushion and a seat back, each of which provided with a spring member which forms an area where temperature controlled air is introduced. In addition, metal meshes are set up on the spring member and an elastomer material is set up on the metal meshes.[0003]This known type of seat apparatus suffers from the disadvantage that it is difficult to efficiently send the controlled air to selected desirable parts of the seat for the seated individual and so the seat apparatus is not as comfortable as it might otherwise be. In addition, this seat apparatus co...
