ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an improved seat having a generally quadrilateral seat frame and a net-like resilient sheet provided bridging between the lateral sides of, and inside, the seat frame to form a seat cushion of the seat.
2. Description of the Prior Art
A seat having a resilient sheet provided bridging between lateral sides of, and inside, a seat frame to form a seat cushion of the seat is well known from, for example, U.S. Pat. Nos. 5,013,089 and 5,553,789 and Japanese Publicized Patent Application No. 8-507935.
The seat has a seat cushion formed from a resilient sheet. Therefore, it is advantageous in that it can be designed to have a different form from ordinary automotive seats, has a good cushioning property and can be formed from a highly permeable seat cushion, pad member and springs may not be specially provided on and in the seat cushion to provide a lightweight design, and can save space very much because of its slim structure.
However, since only the seat cushion is formed from a resilient sheet, the conventional seat is disadvantageous as an automotive seat in that it is heavily vibrated during running of a car, so the driver or passenger cannot stably sit on the seat.
More particularly, the weight of the sitting person is concentrated to under the hip and so he will feel something hard under the hip. In addition, since the resilient sheet forming the seat back will face directly a rear seat. Thus there is a problem that the front seat is influenced by the rear seat, for example, by collision or pushing of the sitting person's knee or the like.
SUMMARY OF THE PRESENT INVENTION
Accordingly, the present invention has an object to overcome the drawbacks of the prior art by providing a seat using a resilient sheet to form a seat cushion which has a good cushioning and a stable holding of a person sitting on a seat.
The above object can be accomplished by providing a seat comprising a generally quadrilateral seat frame and a seat cushion formed from a resilient sheet and provided bridging between lateral sides of, and inside, the seat frame, a cushion member being provided opposite to the resilient sheet and bridging between lateral sides of, and inside, the seat frame, the cushion member being deflectable, under the weight of a sitting person, along with the resilient sheet which mainly receives the weight of the sitting person on the seat.
These objects and other objects, features, aspects and advantages of the present invention will become more apparent from the following detailed description of the present invention when taken in conjunction with the accompanying drawings.
