Embodiment Construction

[0132] A vehicle seat 10 to which the seat structure according to the embodiment of the present invention is applied will be described based on FIGS. 1 to 34 . In addition, arrow UP, arrow LO, arrow FR, arrow RE, arrow RI, and arrow LE appropriately shown in each figure indicate the front (advance direction) with respect to the advance direction of the vehicle on which the vehicle seat 10 is mounted. , rear, upper, lower, right, and left, the following simply indicates that the situation of up, down, front, back, left, and right corresponds to the directions of the above-mentioned arrows.

[0133] FIG. 1 shows a schematic overall configuration of a vehicle seat 10 in a partially cutaway perspective view, and FIG. 2 shows a side view of the vehicle seat 10 . As shown in these figures, the vehicle seat 10 has a seat frame 12 including: a seat frame 14 serving as a cushion frame; and a back frame 16 serving as a seat back frame.

[0134]The seat cushion 18 as a seat is formed by...

Abstract

A seat structure capable of reducing the fatigue of a seated person by the seating thereof for a long time. In a seat (10) for a vehicle, the rear end of the lower layer seat (50) of a cushion material (20) having a front end fixed to the front end of a frame (14) for seat section is elastically connected to the rear end of the frame (14) for the seat section through a movable frame (34) and an elastic torsion bar (46). The cushion material (20) has such a spring zero characteristic that the spring constant of the portion thereof supporting the projected part of the seated person is smaller than the spring constant of the other portions thereof. The seat (10) for the vehicle is formed so as to reduce vibration energy transmitted to the backbone part of the seated person through the frame (14) for the seat section and so that its peripheral parts can change the energy to vibration equivalent to the fluctuation of a living body and the vibration can be transmitted to the seated person through the frame (14) for the seat section. The alpha wave of 10 to 12 Hz produced in a calm awaked state is produced in the brain of the seated person. The vibration in a resonance frequency band is transmitted to the seated person after its amplitude is attenuated.

Description

technical field [0001] The invention relates to a seat structure, in particular to a seat structure of a load-carrying seat installed on vehicles such as motor vehicles. Background technique [0002] Conventionally, as a vehicle seat, a cushion material made of polyurethane foam (hereinafter referred to as polyurethane) is known. The cushion pad structure of the vehicle seat is widely used in which a spring material such as CONTA-MATUT (trade name) provided on the frame for the seat or the frame for the back or a cushion made of polyurethane is attached to the plate. Pad material, and wrap these cushioning pad materials with fibrous material. [0003] Therefore, it is known that the shape (appearance shape) and elastic properties of the cushion material and the compression properties of polyurethane foam have a large influence on the body pressure distribution and vibration absorption of the seated occupant. In addition, by laminating polyurethanes having various propertie...
