敷き込んで座らせていた。Conventional technology Conventional seat chairs for people with disabilities have a base of a back support that can be adjusted to tilt backwards at the tip of a lower frame installed on the seat surface so that the chair can be set in a lying position. is pivoted to the tip of this lower frame, and the front lower part of the chair is supported by the thighs to prevent the entire chair from falling backwards when the weight of the disabled person's upper body is applied to the back support. The thigh receiver is attached to the tip of the rod, and the base of the rod is pivoted so that it can rotate left and right in a horizontal plane. The person with a disability was raised up and placed the back support on his back, and the thigh support, which opened laterally to the left and right, was rotated inward and placed under the thighs of the person with a disability.

発明が解決しようとする問題点 従来の座椅子では、前記のように腿受体が左右外方に回
動する構造であったため、腿受体を外側真横にまで回動
しておかないと、障害者の横側から座椅子を移動させて
背受体を障害者の背中に当てかうことができなかった。Problems to be Solved by the Invention In the conventional seat chair, the thigh receivers had a structure that rotated outward from the left and right as described above, so the thigh receivers had to be rotated to the outside to the side. However, it was not possible to move the chair from the side of the disabled person and place the back support on the disabled person's back.

また、座椅子をセットする場所の側面に壁があるような
場合には腿受体が外方に回動できないために壁際に沿っ
て座椅子をセットできないと謂う問題点があり、更に。In addition, if there is a wall on the side of the place where the chair is set, there is a problem that the seat cannot be set along the wall because the thigh receivers cannot rotate outward. .

座椅子を左右側に並べてセットすることも困難であった
。It was also difficult to set the chairs side by side.

の構成とした。Means for Solving the Problems In order to solve the above-mentioned problems, the present invention takes the following technical measures. That is, in the present invention, the lower end side of the five-back support body 2 is pivotally attached to the left and right sides of the tip of the lower frame 1 installed on the seat surface so as to be rotatable around the horizontal axis, and this back support body 2 and the lower part A lock device 3 is provided between the frame 1 and the back support 2, which can be rotated and set from a substantially vertical state to a state where the back support 2 is appropriately oriented toward the rear side. Thigh receiver 4 placed on the lower side of a person's thigh
The base of a rod 4 with a attached at its tip is pivoted so that the thigh support 4a moves from the front lower part toward the outside and upwards, and then returns to the inside and upwards midway through the movement. The structure is as follows.

きる作用効果を奏する。Functions and Effects of the Invention According to this invention, when a caregiver raises the upper body of a person with a disability who is sleeping face up and applies the back support 2 to the back of the person, the caregiver can freely move the seat from the side of the person with a disability. The thigh receiver 4a is movable and is swung up near both the left and right shoulders of the disabled person.
When the thigh support 4a is rotated downward, the thigh support 4a is eccentrically rotated slightly outward and is automatically placed in a substantially horizontal position under the thigh body of the disabled person, which is extremely easy. A person with a disability can sit on a chair. The chair can be set even close to a wall, and the chair can also be set close to the left and right sides.

障害者を座椅子に座らせることができる。To explain the function of the upper side, in order to seat a disabled person on the chair of the present invention, a caregiver raises the upper body of the disabled person who is lying face up and swings the thigh support 4a upward in advance.
The back support 2 of the chair, which has been set at a predetermined angle with the locking device 5!3, is pressed against the back of the disabled person, and when the rod 4 is rotated forward and downward, the tip of the The thigh support 4a changes from vertical to horizontal and slides from the outer upper part to the lower side of the disabled person's thigh, and even if a load is applied to the back support 2, the chair unexpectedly falls backwards. There is no such thing. In this way, in this chair, when a person with a disability is seated on the chair, the back support 2 is pressed against the back of the person with a disability. It can be moved behind the person and can be set even when there is a wall behind the person, and the thigh support 4a can be spread slightly outward from above and placed horizontally on the underside of the thigh of the person with a disability under gravity. Since the seat is laid out in a row, a person with a disability can sit on the chair without requiring a large space on the left and right sides.
