Problems solved by technology

[0004] However, in the conventional pad supporting device, the relationship between the S spring and the wire is unclear.
Therefore, it is not clear what effect the springs and wires have on the comfort of the seat cushion

other Embodiment approach

[0041] The present invention is not limited to the above-described embodiments, and the following forms and the like are also possible. E.g figure 1 , 2 The shown cushion support device 1 is provided on a seat cushion 11 . However, the pad support device may also be provided on the seat back. In this case, it is preferable that the spring member and the wire extend in the vertical direction, and that the upper and lower ends are attached to the frame (the upper frame and the lower frame).

[0042] In addition, the lowermost portion of the spring member may be located near a point away from the point where the load is most concentrated on the cushion of the seat back toward the direction in which the load is applied.

[0043] Also, with respect to a line connecting the center of the upper frame and the center of the lower frame, the front and rear slopes of the wire may respectively have larger angles than the front and rear slopes of the spring member. The front inclined p...

Abstract

The invention provides a pad supporting device capable of improving conformability of a seat. The pad supporting device for a vehicle (1) comprises a back surface of an elastic supporting pad (11b), a spring part (2) with two end portions installed on a frame (11a) of a vehicle seat (10), and metal wires (3) formed by materials more difficultly elastically deformed than the spring part (2) and with two end portions installed on the frame (11a). The metal wires (3) are disposed at a position farer than distance of the spring part (2) is away from the pad (11b), and a position capable of limiting elastic deformation amount of the pad (11b) or the spring part (2) toward the back surface side direction.

Description

technical field [0001] The present invention relates to a pad support device for a passenger seat that supports the back surface of a pad. Background technique [0002] The passenger seat has a pad and a pad support device that supports the back of the pad. Conventionally, a pad support device includes, for example, an S spring extending between front and rear frames of a seat cushion, and a wire extending between the front and rear frames (see Patent Document 1). [0003] Patent Document 1: Japanese Patent Application Publication No. 5-1350 [0004] However, in the conventional pad support device, the relationship between the S spring and the wire is unclear. Therefore, it is unclear what effect the springs and wires have on the comfort of the seat cushion. Therefore, there is currently a need for a pad support device that can improve the comfort of a seat. Contents of the invention [0005] In order to solve the above-mentioned problems, the present invention is char...
