Description

Stair type Sitting Cushion with thigh support

The present invention relates to a seated cushion used in an ondol room or tatami room. More specifically, the present invention relates to a stepped seated cushion provided with a thigh support for supporting the buttocks while listening to the thighs of the bent legs sitting on the desk legs.

Korea has traditionally lived ondol rooms as residential spaces. Ondol room culture is living on the floor without using a chair or bed, so our traditional seat cushion is called a seat cushion compared to the seat cushion used for chairs and seats. In order to protect from cold and is mainly configured to insert a cushion frame that can be insulated into the cushion seat. This seated cushion is one of the unique household goods in Korea along with Japan, where the living space is a tatami room.

Conventional seated cushions are used to form a cushion skeleton to have a constant thickness as a whole, and the user is sitting on the desk legs, so the cushion of the user's buttocks (hips) and bent legs to balance the upper body is straight in the human body structure Because the body is inclined forward and becomes unstable because it is going to fall backwards, if you maintain this posture for a long time, it will put a strain on your back, and it will exert a force on your legs because it will impair your blood circulation. Several problems appear, such as the inconvenience of pickling quickly.

In particular, the ankle bones of the legs bent with the desk legs are pressed on the floor, causing the feet to sting.

This problem is partially solved by sitting on a cushion, but if you sit for a long time, your ankle bone will be crushed, causing worsening.

In order to overcome these problems, Utility Model Registration No. 272250 (Application Date: Jan. 03, 2002) and Utility Model Registration No. 240424 (Application Date: Apr. 20, 2001) were elected (hereinafter referred to as Stepped Cushion). The staircase cushion of the utility model devises a common cushion as shown in Fig. 1, with two steps of different heights of square cushions, the hips on the higher side and the desk legs on the lower side, and the desk legs on the cushion. When sitting, the bent leg was placed at a lower position to prevent the force from being applied to the leg to prevent the crushing of the ankle bone.

However, the stepped cushion is also difficult to completely eliminate the phenomenon of pressing the astragalus, that is, the thickness of the higher surface should be relatively high in order to prevent the astragalus from being pressed by the stepped cushion, but if the thickness of the cushion becomes thick enough that the astragalus is not pressed, There are various problems such as lack of stability in the posture of the laid person, especially when used with a table or other desk table, such as a problem of not being able to adapt to the height of the table or table desk.

The present invention was devised to solve the problems of the above-mentioned stepped seat cushion, but an object of the present invention is to provide a stepped seat cushion in which a thigh support is formed to form a part supporting the thigh without raising the height of the step so that the astragalus is not pressed. I want to.
