Problems solved by technology

However, the seat formed in this way has a large overall thickness including the spring material and is also heavy.
In addition, in addition to the use of special mechanisms such as forming air holes on the mat, the air permeability is usually not good.
When a special mechanism is used to ensure air permeability, the manufacturing cost increases

Embodiment Construction

[0026] Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments. The seat 1 of this embodiment is equipped with a seat frame 2 , an inner material 5 and a mesh skin 6 .

[0027] like figure 1 As shown in FIG. 2 , the seat frame 2 is provided with a seat back portion 3 and a seat cushion portion 4 . The seat back portion 3 is roughly U-shaped when viewed from the front, and is composed of a first U-shaped frame member 31 with its open end facing downward and a connecting frame material 32 provided on a side constituting the first U-shaped frame member 31. Between the open ends of the frame parts 31b, 31c. The side frame portions 31b, 31c constituting the first U-shaped frame member 31 are curved so as to bulge forward in the vicinity of the center 31d, 31e.

[0028] The seat cushion portion 4 is curved in a U-shape when viewed in plan, and is composed of a second U-shaped frame member 41 and a connecting frame member 42 . ...

Abstract

The invention provides a seat capable of exhibiting improved seated feeling. A lining 5 of one piece structure is spread between a seat back part 3 constituting a seat frame and a seat cushion part 4, and a net-like surface leather 6 of a one-piece structure is laminated on the surface of the lining 5. The net-like surface leather 6 includes a front mesh layer and a rear mesh layer, and the front and rear mesh layers are connected to each other by a number of piles arranged therebetween. Accordingly, the most cushioned part which is around the center part in the net-like surface leather 6, is placed under the buttocks to the vicinity of the waist, which is the part the most weighted by a sitter, a hard touch at the boundary between the seat back part 3 and the seat cushion part 4 due to a frame material is removed and the seated feeling can be improved.

Description

technical field [0001] The present invention relates to a seat using a reticulated skin material. Background technique [0002] Seats with good cushioning properties, such as car seats, are usually equipped with spring materials such as coil springs and S-shaped springs on the seat frame, and a cushion material composed of polyurethane or the like is placed on it, and then nylon leather or cloth, etc. to cover its surface. However, the seat formed in this way has a large overall thickness including the spring material, and is also heavy. In addition, in addition to the use of special mechanisms such as forming air holes on the mat material, the air permeability is generally not good. When a special mechanism is used to ensure air permeability, the manufacturing cost increases. [0003] In order to solve the above problems, in the prior art, a plurality of bundles are used to connect between the surface mesh layer and the inner mesh layer to form a mesh skin with a truss s...
