Embodiment Construction

[0055] Hereinafter, the present invention will be further explained in detail based on the embodiments shown in the drawings. 1 and 2 are views showing a seat structure 10 according to an embodiment of the present invention. The seat structure 10 includes a seat frame 20 and a backrest frame 30 . The seat frame 20 includes side frames 21 and 22 placed at a predetermined distance together with a front frame (not shown). The cushioning member for the seat cushion 40 is placed so as to cover the side frames 21, 22, etc. by stretching across these frames. The back frame 30 includes side frames 31 and 32 placed at a predetermined distance and a top frame 33 for forming the hardest part of the present embodiment, and a cushioning member for the seat back 50 is placed to extend across these side frames 31, 32 etc. so as to cover the side frames 31 and 32 etc.

Abstract

In order to improve seating comfort and vibration absorbency, a structure including a first torsion bar unit 70 disposed in the rear of a seat cushion, and a second torsion bar unit 80 disposed in the front of the seat cushion, and a base net 60 stretched between a rear supporting frame 74 of the first torsion bar unit 70 and a front supporting frame 84 of the second torsion bar unit 80, is provided. Owing to the elastic force of a front torsion bar 81 of the second torsion bar unit 80 positioned in the front of the seat, a sense of stroke at the time of seating is enhanced. Owing to the elastic force of a rear torsion bar 71 of the first torsion bar unit 70 positioned in the rear of the seat, similarly to the conventional structure, a load of a seated person can be sufficiently received and a stable seating comfort can be obtained. Since both the first torsion bar unit 70 and the second torsion bar unit 80 work together to vibration inputted during driving, vibration absorbency is more enhanced than ever.

Description

1. Technical field [0001] The present invention relates to a bottom mesh support mechanism for a seat cushion used in a seat structure formed by stretching across a cushioning member on a seat frame, and to a bottom mesh support mechanism for a seat cushion Seat structure, and in particular to an undernet support mechanism suitable for seat cushions of transport machines such as airplanes, trains, ships, forklifts, motor vehicles, etc., and including such undernet support mechanisms for seat cushions seat structure. 2. Background technology [0002] Seat structures formed by stretching a cushioning member such as a three-dimensional woven fabric (three-dimensional net member) across a seat frame are disclosed in Patent Documents 1 to 5 . When stretching across the seat frame in this way to form a cushioning member, in order to improve bottom contact prevention capability, vibration absorbency, shock absorbency, it is made of cloth such as three-dimensional woven fabric, two...
