2. Description of the Related Art As a head support device for a wheelchair, there is known one in which a backrest of a seat is extended upward and a headrest for supporting a head of a wheelchair user is formed in the extension. .

However, since the above-mentioned extension type headrest has a structure in which the wheelchair itself cannot be folded, the backrest of the seat can be extended upward to be formed integrally with the backrest. It cannot be applied as it is.

[0004]

In view of the above-mentioned problems, the present invention is applied to a folding wheelchair, and in particular, a head or a head that is folded while being mounted in synchronism with the folding of the wheelchair. And providing an upper body support device.

[0005]

The structure of the head supporting device of the present invention made for the purpose of solving the above-mentioned problems is such that the left and right hand-handles 1 and 2 in the wheelchair have an inclined posture.
The left and right rod-shaped support members 3 and 4 which are erected upright and are detachably coupled, and the shafts 5a,
A base member 5 pivoted by 5b in a substantially horizontal posture, and vertically attached to the base member 5 so as to be freely fixed, and
The front member includes a post member 7 having a headrest 8 attached thereto. When the wheelchair is folded and the left and right hand push handles 1 and 2 approach each other, the left and right support members 3 and 4 become base members. It is characterized in that it can be folded close to each other around the pivot point to 5.

In the head supporting device of the present invention having the above-mentioned structure, the left and right supporting members which are erected on the handle of the wheelchair are extendable and contractible so that the position of the headrest is adjusted to the height of the head of the user. be able to. In some cases, a member that is long in the left and right is used as the base member, and a belt member that supports the user's shoulder and chest is detachably provided on the left and right sides. Further, it is desirable that the headrest supported by the head has a structure that can be attached to and detached from the post member. In addition, the position of the headrest can be adjusted up, down, left and right, and forward and backward, and the headrest can be rotated (angled) about each adjustment axis. It is desirable to be able to rotate.

The halved pipe-shaped or inverted U-shaped member is formed by a tightening member for tightening and fixing to the handle or loosening and removing from the handle. Reference numerals 3b and 4b are operation levers of tightening members for tightening and loosening the attachments 3a and 4a to the handles 1 and 2, and 31 and 41 are for fixing the extended and contracted states of the telescopic support members 3 and 4, respectively. The fixing members 31a and 41a provided at the joints of the members 3 and 4 are operating levers for tightening screws in the fixing members 31 and 41.

The left and right stretchable support members 3 and 4 are arranged so that their upper ends are close to each other, that is, the two support members 3 and 4 are in a posture of forming a hypotenuse of a substantially triangular shape in the illustrated example. The upper ends of the support members 3 and 4 are attached to the base member 5 in a horizontal posture by the shaft 5a parallel to the front-back direction of the wheelchair
Pivoted by 5b.

The above-mentioned base member 5 is arranged in a horizontal posture in a direction along the left-right direction of the wheelchair, and here, a post member 7 which will be described later is supported at substantially the center of the front surface side of this member 5. For this purpose, a vertically-oriented cylindrical post support portion 6 is provided, and attachment portions 51 and 52 for belt members 9 and 10, which will be described later, are formed to extend along the length direction of the base member 5. The base member 5 has a two-piece structure including an outer block main body 5A and a core rod 5B inserted in the main body 5A, and the main body 5A and the core rod 5B can be slid relative to each other and can be fixed at a sliding position. You can also

The post member 7 is formed of a pipe material or the like fitted to the support portion 6, and a pillow-shaped headrest 8 is detachably provided on the front surface side. 8a is a bracket provided in the center of the back surface of the headrest 8, 8b is a mounting bracket supported by the bracket 8a and having a substantially U-shape in a plane, 8c
Is a tightening fitting for fitting the fitting 8b to the post member 7 so as to be able to be tightened and loosened, each of which is provided with an adjusting screw having operation knobs 81a, 81b, 81c for adjusting the mounting state. The headrest 8 of the embodiment is adjustable left and right (X axis), front and rear (Y axis), and up and down (Z axis), and is attached so as to be angularly rotatable about each axis.
Reference numeral 6a is an operation knob of the vertical adjusting member of the post member 7.

Belt members 9 and 10 are attached to the left and right extension portions of the base member 5 in a suspended state. The belt members are hung from the user's shoulder to the left and right chests.
A receiving buckle with the lower part of 10 provided on the wheelchair side (not shown)
By fixing the upper body of the wheelchair user to the backrest of the wheelchair in the same manner as a safety belt for automobiles. In the figure, the belt members 9 and 10 are shown with the lengthwise direction omitted. In addition, Br is a backrest in a wheelchair.

EFFECT OF THE INVENTION The head of the present invention, or the supporting device for the head and the upper body is as described above, and the base member having the headrest mounted thereon can be reciprocated on and removed from the handwheel handle of the wheelchair. Since it was pivotally supported on the upper ends of the left and right support members that were erected in an inclined posture as much as possible, the height of the headrest, front and rear, left and right positions, and the angle of the headrest at that position can be adjusted by the user of the wheelchair. It can be adjusted freely according to the position and orientation of the head.

In particular, the supporting device of the present invention is the same as the conventional headrest device of this type in which the wheelchair and the supporting device of the present invention can be folded together by the folding operation of the wheelchair while the device is attached to the wheelchair. There is no inherent effect.
