- the seat includes a closed loop seat frame and a net that is fixed to the seat frame and covers a closed loop portion of the seat frame.
- the seat frame is configured such that the seat frame supports the seating surface of the net in a first extended state, and the seat frame is seated on the net more than in the first extended state.
- the surface can be expanded and contracted to a second position where the surface is supported in the second expanded state.
- a seat 1 includes a seat cushion 2 and a seat back 3.
- the seat cushion 2 includes a closed-loop seat cushion frame (seat frame) 14 and a net 4 whose edge is fixed to a locking wire 14c described later while covering the seat cushion frame 14.
- the seat back 3 includes a closed loop seat back frame (seat frame) 15 and a net 5 whose edge is fixed to a locking wire 15c described later in a state of covering the seat back frame 15.
- Spaces 10 and 11 are formed in the seat cushion frame 14 and the seat back frame 15, respectively.
- the nets 4 and 5 are provided so as to cover the spaces (closed loop portions) 10 and 11, respectively.
- the nets 4 and 5 are elastic members in which synthetic resin fibers made of, for example, a thermoplastic polyester elastomer are woven in a predetermined pattern, and have a characteristic of appropriately dispersing the seated person's weight. Since the nets 4 and 5 are woven in a predetermined pattern, the nets 4 and 5 are breathable and can hold the contact portion coolly and comfortably without confining the body temperature of the seated person.
- a headrest 6 is provided on the upper portion of the seat back 3.
- the seat cushion frame 14 includes an L-shaped (but not limited to right angle) hollow pipe-shaped movable frame 14a having a diameter of 25.4 millimeters and a plate thickness of 1.6 millimeters, for example, and one end of the movable frame 14a. 14a and the other end 14ab are formed in a closed loop shape including a fixed frame 14b slidably inserted. Only one end 14aa of the movable frame 14a and the fixed frame 14b are fixed by welding W. The movable frame 14a is slidable with respect to the fixed frame 14b.
- the seat cushion frame 14 includes a locking wire 14c fixed to the movable frame 14a.
- the locking wire 14c has a notch 14d at a position corresponding to the fixed frame 14b, and moves together with the movable frame 14a as the movable frame 14a slides.
- the edge of the net 4 is fixed to the locking wire 14c with the vicinity of the edge in contact with the movable frame 14a.
- the seat cushion frame 14 is held by legs 9 on a floor (not shown).
- the leg portion 9 includes a slide device 9a and an operation portion 9b that releases a lock (not shown) of the slide device 9a.
- the seat back frame 15 is slidable between a hollow pipe-shaped movable frame 15a having a diameter of 25.4 millimeters and a plate thickness of 1.6 millimeters, and one end portion 15aa and the other end portion 15ab of the movable frame 15a. It is formed in a closed loop shape including a fixed frame 15b inserted into the frame. Only one end 15aa of the movable frame 15a and the fixed frame 15b are fixed by welding W. The movable frame 15a is slidable with respect to the fixed frame 15b.
- the seat cushion frame 15 includes a locking wire 15c fixed to the movable frame 15a.
- the locking wire 15c has a notch 15d at a position corresponding to the fixed frame 15b, and moves together with the movable frame 15a as the movable frame 15a slides.
- the edge of the net 5 is fixed to the locking wire 15c with the vicinity of the edge in contact with the movable frame 15a.
- the seat cushion frame 14 and the seat back frame 15 are configured so that the one end portions 14aa and 15aa and the other end portions 14ab and 15ab of the seat cushion frame 14 and the seat back frame 15 directly hit each other (first position).
- the frame 14 and the seat back frame 15 can be extended and contracted from the state where the one end portions 14aa, 15aa and the other end portions 14ab, 15ab collide with each other to a state separated by the dimension A (second position).
- the seat cushion frame 14 and the seat back frame 15 in the first position can be extended to the second position by moving a jig 12 such as a jack.
- the nets 4 and 5 are not stretched (relaxed) or in a low stretched state (or the seating surfaces of the nets 4 and 5 are unstretched or low stretched) at the first position.
- the seat cushion frame 14 (movable frame 14a) and the seat back frame 15 (movable frame 15a) are placed and fixed.
- the edges of the nets 4 and 5 are fixed to the locking wires 14c and 15c fixed to the movable frames 14a and 15a, and the movement of the edges is restricted.
- the state of the nets 4 and 5 is referred to as a non-expanded state (first extended state).
- This net state is referred to as an extended state (second extended state).
- the movable frames 14a and 15a are slidable with respect to the fixed frames 14b and 15b. Therefore, the movable frames 14a and 15a are slid from the non-stretched state where the nets 4 and 5 are not stretched to the stretched state.
- the production of the seat 1 can be simplified simply by making it.
