Description

  The present invention relates to a headrest, and more particularly to a headrest fixed to a support member that supports a backrest of a wheelchair.

In recent years, there is a case where a user who uses a wheelchair is put on the wheelchair together with the wheelchair.
By the way, although a general wheelchair is provided with a backrest, a headrest is not provided. In such a case, a user who rides a car with such a general wheelchair is in a car that travels without a headrest.
For this reason, if the car on board suddenly brakes or collides with another car, there is nothing to support the head of the user seated in such a general wheelchair. The neck may be damaged.

Therefore, a headrest to be attached to a wheelchair has been proposed.
For example, as a headrest to be attached to such a wheelchair, comprising a pillow part, an inverted substantially U-shaped support pipe that supports the pillow part to be lifted from both sides, and an attachment fixed to the backrest frame of the wheelchair, There has been proposed a headrest in which a lower end portion of a support pipe is inserted and fixed to a fixture from above (Patent Document 1).
According to this wheelchair headrest mechanism, the pillow portion for supporting the head of the user seated in the wheelchair can be detachably attached to the wheelchair.

JP 2001-327541 A

  By the way, when the wheelchair is not used, it is folded in the direction of narrowing the width. When the wheelchair is folded, the headrest of Patent Document 1 cannot be folded from the wheelchair because the pillow portion and the inverted substantially U-shaped support pipe that supports the pillow portion cannot be folded. That is, when using a wheelchair, it is necessary to attach the headrest after expanding the wheelchair.

The width of the wheelchair varies depending on the vehicle type. For this reason, when the headrest attached to a certain wheelchair is attached to another wheelchair having a different width, it is necessary to adjust the width of the headrest.
However, the headrest of Patent Document 1 needs to adjust the width of the inverted substantially U-shaped support pipe to the width of the wheelchair and adjust the portion where the support pipe and the pillow portion are joined. It is complicated.

  An object of this invention is to provide the headrest which can be folded with a wheelchair and can adjust width | variety easily.

(1) A headrest fixed to a support member that supports a backrest of a wheelchair,
A pair of fixed portions fixed to the support member, extending upward from below and formed in a cylindrical body;
A pair of shaft portions respectively inserted from the lower end side into the pair of fixed portions from above;
The left and right side edges are fixed to the upper end sides of the pair of shaft portions, formed in a cloth-like body made of a flexible material, and provided with a main body that supports the head of a user seated in the wheelchair,
The main body includes a cylindrical shaft portion insertion portion in which the shaft portion is inserted into one side edge, and a first surface joint formed in a range from one end portion to the center in the left-right direction of one surface. And a second surface joint portion that is formed in a range from the center to the other end portion and is detachably joined to the first surface joint portion,
A pair of the main body is formed by inserting one of the shaft portions into the shaft portion insertion portion, folding the other shaft portion around a fulcrum, and joining the first surface joining portion and the second surface joining portion. A headrest fixed to the shaft portion of the head.

According to the structure of (1), a headrest is fixed to the support member which supports the backrest of a wheelchair, and is provided with a pair of fixing | fixed part, a pair of axial part, and a main body.
The pair of fixing portions are fixed to a support member of the wheelchair, extend upward from below, and are formed in a cylindrical body.
The pair of shaft portions are respectively inserted into the pair of fixed portions from above from the lower side.
The main body has left and right side edges fixed to the upper end sides of the pair of shaft portions, is formed in a cloth-like body made of a flexible material, and supports the head of a user seated in a wheelchair.
The main body has a shaft portion insertion portion, a first surface joint portion, and a second surface joint portion.
The shaft portion insertion portion is formed in a cylindrical shape on one side edge, and the shaft portion is inserted therein.
The first surface bonding portion is formed in a range from one end to the center in the left-right direction of one surface.
The second surface joint portion is formed in a range from the center to the other end portion, and is detachably joined to the first surface joint portion.
Then, the main body has one fixed portion inserted into the shaft portion insertion portion, the other fixed portion is folded back to a fulcrum, and the first surface joint portion and the second surface joint portion are joined, so that the pair of shaft portions are joined. Fixed.

According to such a configuration, when the wheelchair is folded, the pair of fixing portions fixed to the support member of the wheelchair approach each other. And since the main body that supports the head of the user seated in the wheelchair is formed of a flexible material in a cloth-like body, when the wheelchair is folded, both side edges of the main body are inserted into the pair of fixing portions. Following the shaft part, they are adjacent to each other and the middle part is bent.
Therefore, the wheelchair can be folded with the headrest attached to the wheelchair.

Moreover, according to the structure of this invention, when attaching the headrest attached to a certain wheelchair to the other wheelchair from which width differs, the width | variety of a headrest is adjusted in the following procedures.
First, the joint between the first surface joint portion and the second surface joint portion of the main body in the headrest adjusted to the width of a certain wheelchair is released.
And a pair of axial part is each inserted in a pair of fixing | fixed part fixed to the other wheelchair. The width between the pair of shafts at this time is the width of the headrest in another wheelchair.

Next, the main body in which one shaft portion is inserted into the shaft portion insertion portion is folded back with the other shaft portion as a fulcrum, and the first surface joint portion and the second surface joint portion are joined.
Thereby, the operation | work which attaches the headrest attached to the certain wheelchair to the other wheelchair from which width differs is completed.

Thus, while adjusting the attachment position with the main body, without adjusting the width of the pair of shaft portions that support the main body, the pair of shafts is simply connected to the pair of fixing portions fixed to the support member of the wheelchair. The headrest attached to a certain wheelchair can be attached to another wheelchair having a different width simply by inserting the portion and folding back the main body with the shaft portion as a fulcrum.
Therefore, it is possible to provide a headrest that can be folded together with the wheelchair and can be easily adjusted in width.
