To load be concentrated in horizontal direction load application point.As a result side forming portion can relatively easily be collapsed.
In contrast, as shown in figs. 8 and 12, when the chair 10 for making present embodiment becomes open mode, by the 3rd
The center side direction of the effect of groove portion 23, the 1st lateral side regions 41 and the 2nd lateral side regions 42 relative to the horizontal direction of folding seat 10
Different directions from each other gently bend.According to the structure, the 1st side is dispersed to the load of vertical direction for chair 10
The lateral side regions 42 of face region 41 and the 2nd.Thus, for example even if the load of horizontal direction acts on certain point of the 1st lateral side regions 41,
The load of the vertical direction that the 2nd lateral side regions 42 are born also is difficult to the load of the horizontal direction for focusing on the 1st lateral side regions 41
Application point.Similarly, even if the load of such as horizontal direction acts on certain point of the 2nd lateral side regions 42, the 1st lateral side regions 41
The load of the vertical direction born also is difficult to the application point of the load of the horizontal direction for focusing on the 2nd lateral side regions 42.Thus,
According to present embodiment, compared with side forming portion 40 to be formed as the situation of simple arc-shaped, uprise can resistance to load.
Here, applicant is in order to confirm the resistance to load of the chair 10 of above-mentioned embodiment, with JIS S1203：1998 " families
The test of the test method of tool-chair and stool-intensity and durability " is implemented on the basis of regulation, has carried out following test.The examination
Proved recipe method is, via the small-sized seat surface loading pad of a diameter of 200mm, to the central authorities of seat surface forming portion 30 side of the power for specifying to be applied
Method.As a result, the chair 10 for having obtained above-mentioned embodiment can bear the result of the load of 1500N.
In addition, present invention mentioned above is not limited to above-mentioned embodiment, it is applicable in the range of without departing from its main idea
In various embodiments.
Board member 20 is not limited to the resin materials such as polypropylene, it is also possible to be the light-weight metals such as such as aluminium, timber etc..In the feelings
Under condition, by replacing groove portion 21～24 and arranging such as hinge etc., board member can be constituted in the way of flexible.
2nd seat surface region 32 of seat surface forming portion 30 can not connect with the 1st seat surface region of another seat surface forming portion 30
Connect.That is, under the open mode of chair 10, it is also possible to only the 2nd seat surface region 32 of a board member 20 is placed in into another
1st seat surface region 31 of board member 20.
Chair 10 is sized to according to suitably being changed using object, use environment, application target etc..
Additionally, the 4th groove portion 24 can also adopt for example following structure.That is, detailed content is not shown, makes the 4th 24 one-tenth of groove portion
For the groove of mountain folding.By the 3rd lateral side regions 43 of 2 pieces of board members 20,20 inner side respectively to chair 10 i.e. to the 3rd opposite side
The approximating side bending in region 43.Then, by the surface element bonding of the 3rd lateral side regions 43 toward each other.According to the knot
Structure, the 2nd lateral side regions 42 and the 3rd lateral side regions 43 using the 4th groove portion 24 as crease line, surface element that can be to each other away from
Direction bending.Thus, 2 pieces of board members 20,20 can each other be opened and closed the 4th groove portion 24 as crease line.Therefore, be obtained with it is upper
