Description
[0001] The present disclosure relates to a wheelchair and a
headrest therefor.
[0002] Wheelchairs are essential equipment for the elderly
and infirm or patients who have difficulty with mobility.
[0003] Patients purchase and use wheelchairs suitable for
their bodies. In order for the elderly and infirm to use
wheelchairs more conveniently, it is preferable to provide a
headrest. In the case of the elderly and infirm, it is more
preferable that a suitable headrest is provided according to
the deformation of the body. Nevertheless, headrests
introduced on the market are expensive or inconvenient
because their usage mode is constantly limited.
[0004] As for a wheelchair having a conventional headrest,
Korean Patent Application Publication No. 10-2014-0008072
discloses a wheelchair having a posture assistance function.
[0005] In the prior art, a headrest fixed to a backrest is
proposed. However, a general foldable wheelchair has a
problem that cannot be fixed because there is no fixed
backrest. In addition, there is a problem that manufacturing
costs are high because a number of links are provided.
[0006] The present disclosure has been made in view of the above-described background, and proposes a wheelchair that can be deformed and adjusted according to the size of the wheelchair, and a headrest therefor.
[0007] In addition, the present disclosure proposes a wheelchair that can be deformed and adjusted according to a user's body size and aging degree, and a headrest mounted on the wheelchair.

According to the present disclosure, it is possible to increase a convenience at the time of using the wheelchair.
[0030] According to the present disclosure, a headrest fixing structure may be provided in a left-and-right separation type so as to be conveniently mounted.
[0031] According to the present disclosure, since the height of a headrest holder can be adjusted, it is possible to cope with a user's height.
[0032] According to the present disclosure, since Velcro is
applied so as to attach a headrest, it is possible to place the headrest in an accurate position corresponding to a user's body.
[0033] According to the present disclosure, the width of the
Velcro is adjusted such that the headrest is mounted corresponding to the width of the wheelchair.
[0034] According to the present disclosure, the front-and rear widths of the headrest can be adjusted by adjusting the
tension of the headrest and the angle of a headrest pole.
[0035] According to the present disclosure, since a bracket of a fixing structure is installed at an obtuse angle, it does not cause interference with a user's body, thereby
enabling a user's convenient use.
[0036] According to the present disclosure, a C-shaped pole can expand and contract, such that it can be mounted on any chair corresponding to the left-and-right width of the wheelchair.
[0037] According to the present disclosure, since the
fastening can be completed only with the headdress, the user
can conveniently use the wheelchair, and there is no need to
separately provide Velcro on the pole.
[0038] According to the present disclosure, since the
headrest is also fixed to the upper pole, the headrest does
not droop down.
[0039] According to the present disclosure, since the
headrest is supported on three sides, the headrest does not

skilled in the art who understand the spirit of the present
disclosure will be able to easily propose other embodiments
falling within the scope of the same spirit by adding,
modifying, and deleting elements. However, this also falls
within the spirit of the present disclosure.
[0067] Fig. 1 is a front perspective view of a wheelchair
when a headrest of an embodiment is mounted thereon, Fig. 2
is a perspective view of the headrest mounted on a frame of
the wheelchair, Fig. 3 is a perspective view of only the
headrest, and Fig. 4 is a perspective view showing a state in
which a head of the headrest and a headrest pole are
separated.
[0068] Referring to Figs. 1 to 4, a wheelchair H includes
folding bars H7 that intersect with each other in an inclined
direction and are foldable with each other, wheels Hi
provided on left and right ends of the folding bars H7, a
seat H2 provided on the upper surfaces of the folding bars H7
and on which a user sits, support bars H8 supporting the
folding bars H7 back and forth, vertical frames H3 extending
vertically from the rear portions of the support bars H8,
horizontal frames H4 extending rearward from the upper ends
of the vertical frames H3, and handles H5 provided on the
horizontal frames H4 and held by the user.
[0069] A headrest 1 capable of supporting a user's head may
be fixed to the pair of vertical frames H3. A backrest H6
may be provided between the pair of vertical frames H3. The
backrest H6 and the seat H2 may be provided with a cloth or a
freely foldable member so as to be folded when the folding
bars H7 are folded.
[0070] The headrest 1 may include headrest fixtures 40
fastened to the vertical frames H3 such that the headrest is
fixed to the wheelchair H, a pair of headrest poles 20
connected to the headrest fixtures 40 so as to be fastened to
the lower end and extending upward, and a headrest head 10
connecting the pair of headrest poles 20 left and right.
[0071] The headrest head 10 supports a user's head such that
the user can use the wheelchair more conveniently.
[0072] The vertical frames H3 may be provided with a pair of
left and right frames, the headrest poles 20 may be provided
with a pair of headrest poles, and the headrest fixtures 40
may be provided with a pair of headrest fixtures.
[0073] The headrest fixtures 40 may be provided to be freely
fixed to and separated from the wheelchair. As a result, it
can be seen that the headrest 1 is fastened to the frame of
the wheelchair provided as a ready-made product so as to
support a patient's head.
[0074] No matter what size, specification, and size the
ready-made wheelchair has, the separate headrest fixtures 40
may be fastened to the respective frames, and the headrest
head 10 may be provided in the form of connecting the two
poles 30. Therefore, the headrest 10 can cope with any type
of wheelchair.
[0075] Fig. 5 is a side view of the headrest, wherein (a) is an entire right side view of the headrest, (b) is a right side view when the headrest head is removed, (c) is a perspective view of only one headrest pole, and (d) is a view of the upper end of the headrest pole.
[0076] Referring to Fig. 5, a second Velcro 21 may be fastened to the outer surface of the upper portion of the headrest pole 20. Here, it can be understood that the second Velcro 21 has a male structure as a rough surface.
[0077] A first Velcro corresponding to the second Velcro 21 may be provided on the headrest head 10. Therefore, the headrest head and the headrest pole may be fastened to or separated from each other. Due to the Velcro fastening
structure, the fastening and separation is easy and the user can conveniently use the wheelchair.
[0078] The headrest pole 20 may be provided to be curved forward. Thus, in response to the sitting angle of the
elderly and infirm with a bent waist, the user can use the wheelchair more conveniently.
[0079] The second Velcro may be mounted on the headrest pole, the first Velcro corresponding to the headrest head may be
provided, and the Velcros mating with each other may be fastened to each other.
[0080] The headrest pole and the headrest head may be more clearly understood by other drawings later.
[0081] Fig. 6 is a rear view of the headrest, wherein (a) is a view explaining that the height of the headrest pole is adjusted vertically at a headrest pole insertion hole, and (b) is a view explaining a change in the height of the
headrest pole.
[0082] Referring to Fig. 6, the headrest fixture 40 is provided with a first pole holder 41. The headrest pole 20 may be inserted into the first pole holder 41.
[0083] The fastening operation of the headrest pole 20 in the first pole holder 41 may be performed by selectively
fitting a stopper including a cap 22 and a spring 23 into holes 50a, 50b, and 50c having different positions. Due to the operation of the stopper and the hole, the height of the headrest is adjustable.
[0084] Referring to Fig. 7, the cap 22 and the spring 23 providing a force pushing the cap 22 outward are provided inside the lower end of the headrest pole 20. The cap 22 passes through a through hole defined in the headrest pole 20
and protrudes outward. In order to accurately fix the vertical position of the cap 22, the other end of the spring 23 may be fastened to the inside of the pipe.
[0085] The cap 22 may selectively pass through the holes 50a,
b, and 50c of the first pole holder 41. At a position at which one of the cap 22 and the hole is fitted to the other, the positions of the headrest pole 20 and the headrest fixture 40 may be fixed.
[0086] Referring back to Fig. 6, when the cap 22 is fitted to the third hole 50c, the height of the headrest head 10 may be the lowest. In this case, it may respond to a user with a low seated height. On the contrary, when the cap 22 is
fitted to the first hole 50a, the height of the headrest head may be the highest. In this case, it may respond to a user with a high seated height.
[0087] Figs. 8 to 12 are views explaining the headrest head
in detail, wherein Fig. 8 is a view explaining the adjustment of the horizontal size of the headrest head, Fig. 9 is a rear view of the headrest head with the horizontal size adjusted,
Fig. 10 is a front view (a) and a rear view (b) when the
headrest head is fully expanded, Fig. 11 is a view showing
that the height of the headrest head is adjusted, and Fig. 12
is a view explaining the tension adjustment of a headrest
head.
[0088] First, referring to Fig. 8, the headrest head 10
includes a cushion portion 3 that may gently wrap or support
a user's head, and first and second fixing portions 4 and 5
that are provided on both sides of the cushion portion 3 and
may be fixed to the headrest pole 20.
[0089] One of the first and second fixing portions 4 and 5
may be provided in a state of being fixed to one of the
headrest poles.
[0090] Fig. 8(a) shows a state in which the horizontal
length of the headrest head 10 is adjusted to be the longest,
Fig. 8(b) shows a state in which the horizontal length of the
headrest head 10 is adjusted to be the shortest, and Fig.
8(c) shows a state in which the horizontal length of the
headrest head 10 is adjusted to be middle.
[0091] Referring to Fig. 8, it can be seen that the position
of the headrest pole changes according to various positions
at which the Velcro provided on the headrest and the Velcro
provided on the outer surface of the headrest pole are
fastened to each other. In other words, it can be seen that
the headrest pole is applied to wheelchairs having different
sizes. In Fig. 9, it can be observed that the headrest head
is adjusted to the state of Fig. 8 (c).
[0092] Referring to Fig. 10, the type of Velcro provided on
the fabric forming the outer surface of the headrest head may be known.
[0093] Specifically, a rough second Velcro 2b may be
provided at the end of the Velcro that is provided to the left and right of the headrest head 10, and a soft first
Velcro 2a may be provided at the others. It has been described that the second Velcro 21 is provided on the headrest pole 20. Here, it can be said that the second Velcro 2b has a male structure as a rough surface structure,
and the first Velcro 2a has a female structure as a smooth surface structure. On the contrary, although provided conversely, it is not preferable to provide a rough structure on a surface that the user's hand can contact, and thus the
present embodiment is preferred.
[0094] With this structure, the soft first Velcro 2a of the fixing portions 4 and 5 may be fastened to the second Velcro 21 of the headrest pole 20. The rough second Velcro 2b of
the fixing portions 4 and 5 may be fastened to the soft first Velcro 2a of the fixing portions 4 and 5, and it is possible to provide the headrest head having a long horizontal length (see Fig. 8(a)). The rough second Velcro 2b of the fixing
portions 4 and 5 may be fastened to the soft first Velcro 2a of the cushion portion 3, and it is possible to provide the headrest head having a short horizontal length (see Fig.
8(b)).
[0095] Fig. 11 is a view showing that the headrest head is movably installed in various positions of the headrest pole by a Velcro mechanism. Since the Velcro is easily fastened and separated, the height of the headrest head may be easily
adjusted. In addition, it is already seen that the height of the headrest head may be adjusted by selectively fastening the cap 22 to the holes 50a, 50b, and 50c.
[0096] Fig. 12 is a view showing that the head is movable back and forth by adjusting the tension of the headrest head. Since the headrest head is loosely fastened, the position of
the headrest head may be adjusted in the front-and-rear direction.
[0097] Fig. 13 is a side view explaining that the position of the headrest is adjustable by adjusting the bending angle
of the headrest pole. Specifically, it can be seen from Fig. 13(a) that the headrest pole 20 is bent forward at a bending angle A as it goes upward, it can be seen from Fig. 13(b) that the second Velcro 21 is fixed to the upper portion of
the headrest pole 20, and it can be seen from Fig. 13(c) that the headrest head 10 is fixed to the second Velcro 21.
[0098] Referring to Fig. 13(c), it can be seen that it is possible to more actively respond to elderly people with a
bent spine and waist.
[0099] By providing various types of headrest poles having different bending angles A of the headrest poles, the headrest suitable for the user's body structure may be
provided. Of course, it is also possible to adjust the headrest bending angle A by providing a specific rotational structure. For example, it may be adjusted using a hinge joint and a joint fastener.
[00100] Figs. 14 and 15 are views before and after the mounting of a headrest fixture, wherein (a) is a front perspective view, and (b) is a horizontal cross-sectional view of the front perspective view.
[00101] Referring to Figs. 14 and 15, the headrest fixture 40 may include a fixing frame 43 on which the vertical frame H3 is seated, a rotating portion 45 capable of holding the vertical frame H3 by rotating about the hinge 44 with respect to the fixing frame 43, a first pole holder 41 into which the headrest pole 20 is inserted, and an extra second pole holder
42 into which another pole is inserted. A ringer support may
be exemplified in the other pole that may be inserted into
the second pole holder 42.
[00102] A second pole fixture 47 may protrude from the inner
space of the pole holder 42. The second pole fixture 47 may
hold the lower end of the ringer support such that the height
of the ringer support is maintained.
[00103] The fastening of the headrest fixture 40 will be
described.
[00104] A first seating surface 48 having an outer surface
corresponding to the vertical frame H3 is provided on the
front surface of the fixing frame 43. A second seating
surface 49 having an outer surface corresponding to the
vertical frame H3 is provided on the rear surface of the
rotating portion 45.
[00105] When the vertical frame H3 is seated on the first
seating surface 48, the height of the headrest fixture 40 may
be adjusted. The second seating surface 49 may allow the
vertical frame H3 to be seated by rotating the rotating
portion 45 in a state in which the height of the headrest
fixture 40 is aligned. The fastening position of the
rotating portion 45 may be fixed, without being released by a
force pushed by the fastener 46.
[00106] The headrest fixture may be fastened to the vertical
frame H3 by the operation of the first seating surface 48 and
the second seating surface 49 pushing the vertical frame H3 in two directions. The extension direction of the fixing frame and the rotating angle of the rotating portion may form an obtuse angle a, such that the user's body does not contact the movable portion.
[00107] In other words, the user's body approaches from the front to the rear, and the edge of the user's back contacts the fixing frame. At this time, when the outer surface (bottom in the drawing) of the rotating portion gets caught
in the body, there is a risk of injury. Therefore, the outer surface of the rotating portion may form an obtuse angle with the outer surface of the fixing frame. Similarly, when drawing an extension line extending the outer surface of the
rotating portion, it can be understood that the extension line and the rear surface of the wheelchair meet on the inner surface of the place where the headrest fixture is placed.
[00108] According to the above-described headrest fixture,
the headrest fixture may be fastened and used for a wheelchair of any configuration having any frame extending in the vertical direction or the inclined vertical direction.
[00109] Fig. 16 is a rear view of the headrest fixture.
[00110] Referring to Fig. 16, it can be seen that the vertical frame H3 is fastened in front of the fixing frame 43, and the first pole holder 41 and the second pole holder 42 extend vertically from the rear of the fixing frame 43.
[00111] The fastener 46 pushes the rotating portion 45 located in front of the fastener 46, such that the fixing frame 43 and the rotating portion 45 may hold the vertical frame H3 firmly.
[00112] According to the present embodiment, the headrest of the wheelchair may be fixed and used regardless the user's body structure and the type and size of the wheelchair.
[00113] However, although the headrest can be mounted in the embodiment, it is inconvenient to fix the mounted headrest, the headrest head may droop down, the Velcro has to be
provided on the pole so as to fix the headrest, and two poles are fixed to the headrest head. Therefore, there is a big problem in the movement of the headrest head.
[00114] In the following, another embodiment of the headrest
that solves the above-described problem is provided. The description of the above embodiment is applied to parts that are not described in detail, and the description thereof is omitted.
[00115] Fig. 17 is an unfolded rear plan view of a headrest head according to another embodiment, wherein (a) is a schematic view, (b) is a rear view of an actual product, and (c) is a front view of the actual product.
[00116] Referring to Fig. 17, the headrest head according to another embodiment includes a cushion portion 130 supporting the user's head from the rear, first and second left and right fastening portions 110 and 120 provided on the left and
right sides of the cushion portion 130, and an upper fastening portion 140 extending further upward from the cushion portion 130. The left and right fastening portions may be said to correspond to the fixing portions 4 and 5 of
the above-described embodiment and may be referred to as fixing portions.
[00117] At least two Velcros may extend in parallel across the cushion portion 130 and the left and right fastening
portions 110 and 120. The Velcro may include a soft first Velcro 2a extending across the cushion portion to the left and right fastening portions, and a rough second Velcro 2b provided at the end of the first Velcro 2a.
[00118] The first and second left and right fastening portions 110 and 120 may surround the first headrest pole
(see 150 in Fig. 20) and the second headrest pole (see 160 in Fig. 20). The second Velcros 2b of the first and second left and right fastening portions 110 and 120 may be fastened to each other in correspondence with the first Velcro 2a of the
cushion portion 130.
[00119] The second Velcro 2b extending left and right from the upper end of the upper fastening portion 140 may be provided. The upper fastening portion 140 may surround the
intermediate pole (see 170 in Fig. 20) to the rear. The second Velcros 2b of the upper fastening portion 140 may be fastened to each other in correspondence with the first Velcro 2a.
[00120] With this configuration, the first and second left and right fastening portions 110 and 120 support the left and right of the headrest head, and the upper fastening portion 140 supports the upper side of the headrest head. Since the
upper fastening portion 140 is pulled and fixed above the headrest head, drooping of the headrest head does not occur.
[00121] In addition, since the upper fastening portion 140 fixes the headrest head, the left and right fastening
portions 110 and 120 do not need to be self-fastened to the pole 20. Accordingly, there is an advantage in that the inconvenience of processing Velcro on the outer surface of the pole 20 is eliminated. Of course, it is possible to
expect the advantage that the fastening of the headrest head is facilitated.
[00122] In addition, since the headrest head is fixed at three corners, that is, the left, right, and upper corners, it is possible to obtain the advantage of reducing or eliminating the shaking of the headrest head.
[00123] A plurality of small pieces of biochips may be accommodated in the inner space of the cushion portion 130. The biochip does not deteriorate the cushioning force, and water may be easily drained after washing. The biochip may have a cut straw shape.
[00124] Fig. 18 shows a state in which the headrest head is folded in another embodiment, and it can be seen that the Velcros are fastened to correspond to each other.
[00125] Referring to Figs. 19 to 21, in a state in which the headrest head 100 is fastened, not only the left and right fastening portions 110 and 120 but also the upper fastening portion 140 are fixed, and the headrest head 100 may be
positioned more firmly (see Fig. 19). Since the headrest is fixed in three directions, the shaking may be prevented.
[00126] In the headrest head 100, when the Velcro is separated from each pole, it can be seen that no Velcro is
provided on the pole (see Fig. 20).
[00127] Meanwhile, the first headrest pole 150 includes a first extension portion 151 extending vertically and a second extension portion 152 extending horizontally from the upper
end of the first extension portion 151. Similarly to the first headrest pole 150, the second headrest pole 160 includes a first extension portion 161 and a second extension portion 162.
[00128] Intermediate poles 170 may be fitted at the ends of the second extension portions 152 and 162. The second extension portions 152 and 162 may be fitted at both ends of the intermediate pole 170.
[00129] When the second extension portions 152 and 162 are provided to be long, the upper fastening portion 140 may be
fixed to the second extension portion. In this case, the intermediate pole 170 may not be needed.
[00130] The intermediate pole 170 is a component separate from the headrest poles 150 and 160 and may be fastened to
the headrest poles 150 and 160 later.
[00131] The intermediate pole 170 may be fastened to the second extension portions 152 and 162 by fastening tools such
as screws.
[00132] When comparing Fig. 20 with Fig. 21, it is possible to understand the fastening and operation of the intermediate pole.
[00133] Figs. 22 to 25 are photographs of actual products of
the headrest head. Fig. 22 is a front view of the headrest head. Fig. 23 is a rear view of the headrest head. Fig. 24 is a rear view of a wheelchair when the headrest is mounted thereon. Fig. 25 is a front view of the wheelchair when the
headrest is mounted thereon.
[00134] Referring to Figs. 22 to 25, it is possible to prevent the drooping of the headrest head through the upper fastening portion 140 and it is possible to eliminate the
inconvenience of processing Velcro on the outer surfaces of the headrest poles 150 and 160. The fastening of the headrest head is facilitated, and it is possible to expect the advantage of reducing or eliminating the shaking of the
headrest head by using the support for the three corners.
[00135] Fig. 26 is a bottom perspective view showing the intermediate pole, and Fig. 27 is an enlarged view of the intermediate pole in Fig. 26.
[00136] Referring to Figs. 26 and 27, part of the second extension portions 152 and 162 of the left and right poles
may be inserted into both ends of the intermediate pole 170. The length at which the second extension portions 152 and 162 are inserted into the intermediate pole 170 may be adjusted. For example, when the horizontal width of the wheelchair is
large, the lengths of the second extension portions 152 and 162 inserted into the intermediate pole 170 may be shortened.
[00137] The lengths of the second extension portions 152 and 162 may be provided in a size corresponding to the
specifications of all wheelchairs. For example, when the lengths of the second extension portions 152 and 162 are excessively short, the second extension portions 152 and 162 cannot overlap the intermediate pole 170 with respect to the
wheelchair. Thus, the fastening may be impossible. In another case, when the length at which the second extension portions 152 and 162 and the intermediate pole 170 overlap is short, it may be difficult to obtain a sufficient and stable
support effect.
[00138] Both may be fastened in a state in which the length at which the second extension portions 152 and 162 are inserted into the intermediate pole 170 is adjusted.
Therefore, it is possible to achieve a solid fastening of the two members. The fastening of the two members may be performed by fastening a screw or the like to each of the two members.
[00139] In order to firmly fasten the intermediate pole 170
to the second extension portions 152 and 162, the intermediate pole 170 may be provided with a hollow tube 171, a raised portion 172 that is elongated on either side of the tube 171, and at least one slit 173 that is elongated in the same direction as the raised portion 172 in the raised portion 172
[00140] The raised portion 172 is provided for, when a
fastener 174 such as a screw fastens the intermediate pole
170 to the left and right poles 150 and 160, supporting the
fastener 174 more firmly, so as to improve the reliability of
mutual fastening of the intermediate pole and the extension
portion.
[00141] The user may place the fastener 174 in the slit 173
and allow it to be easily inserted inside. For example,
after placing the screw in a predetermined position while
looking at the inner left and right poles through the slit,
the user can turn the screw with a small force. In this case,
even when not a professional worker, a worker can fasten the
screw.
[00142] Grooves may be provided in the second extension
portions 152 and 162 such that the fastener 174 is placed
thereon, or a groove may also be provided in the slit 173.
Therefore, it is possible to more actively and conveniently
respond to the specifications of a predetermined wheelchair.
[00143] Of course, various fastening devices for the
intermediate pole and the left and right poles may be
provided. However, the length of the left and right width of
the pole may be adjusted, the pole may be fixed in the
adjusted state, and the headrest may be fixed at the left,
right, and upper sides.
[00144] According to another embodiment, it is possible to solve the problem that the fixing of the mounted headrest head is inconvenient and drooped down. In addition, the inconvenience of having to provide Velcro on the pole so as to fix the headrest head is eliminated. In addition, since the headrest head is fixed on three sides, there is an advantage that the shaking of the headrest is reduced or eliminated.
[00145] Even according to the other embodiment, there is a
problem that the fastening portion for the intermediate pole 170 and the headrest pole 150 and 160 shakes. In addition, there is a problem that each pole is easily deformed upon external impact.
[00146] The inventors further conducted additional research and development in order to solve the above problems. As a result, further another embodiment is proposed as follows.
[00147] Figs. 28 to 30 are views explaining a headrest
mounted on a wheelchair according to another embodiment. Fig. 28 is a view showing that contact portions in a state in which an intermediate pole 270 and first and second headrest poles 250 and 260 are separated are overlapped vertically,
Fig. 29 is a cross-sectional view of a portion of the intermediate pole, and Fig. 30 is a cross-sectional view of a part of second extension portions 252 and 262 of the first and second headrest poles 250 and 260.
[00148] The description of the above embodiments is applied to parts that are not described in further another embodiment.
[00149] Referring to Figs. 28 to 30, concave and convex portions 275 and 282 extend in the longitudinal direction of
each pole on the surfaces of the intermediate pole 270 and the first and second headrest poles 250 and 260.
[00150] The concave and convex portions 275 and 282 may increase the rigidity of the pole. The concave and convex portions 275 and 282 improve the feeling of contact when the user holds them by hand, such that users with reduced senses
can conveniently handle the headrest pole and the headrest head. Even when a mark occurs on the surface of the pole due to the concave and convex portions, it is difficult to identify the mark with the naked eye, thereby improving
product properties.
[00151] Similarly to the other embodiment, the intermediate pole 270 may be provided with a raised portion 272 to prevent damage to the intermediate pole 270 when a fastener 274 is
fitted thereto. However, unlike the other embodiment, the intermediate pole 270 according to further another embodiment is not provided with a slit that is elongated in one direction. This is because the slit may lower the strength
of the intermediate pole 270.
[00152] In further another embodiment, only the groove 273 is provided to be elongated in the longitudinal direction of the raised portion 272. An approximately circular hole 276 is
provided in a certain place of the groove 273 such that the fastener 274 is fitted thereto. Since only the groove 273 is processed by opening the raised portion 272, it can be expected that the strength of the intermediate pole 270 is
greatly improved as a whole.
[00153] Two holes 276 may be provided to correspond to the first and second headrest poles 250 and 260. The present disclosure is not limited thereto, and a different number of
holes 276 may be provided to cope with different wheelchairs.
[00154] The end of the fastener 274 may contact one surface of the first and second headrest poles 250 and 260 and pass through the surface. That is, the intermediate pole and one of the headrest poles may be respectively fastened by the fastener 274.
[00155] In order to firmly fasten the fastener 274 to the
headrest poles 250 and 260, a reinforcing tube 280 may be
further inserted into the inner surface of the headrest poles
250 and 260. The reinforcing tube 280 has a tube shape
having a predetermined thickness, and the outer surface of
the reinforcing tube 280 may contact the inner surfaces of
the headrest poles 250 and 260.
[00156] In order to fasten the reinforcing tube 280 to the
headrest poles 250 and 260, a fastening portion 281 may be
formed on the outer surfaces of the headrest poles 250 and
260. The fastening portion 281 is a forced deformation
portion and may be deformed to mark the outer surface of the
pole with a sharp member, such that the two members are
fastened to each other by deformation.
[00157] According to the further another embodiment, since
the fastening between the poles is made more firmly, the
shaking may be prevented.
[00158] According to the present disclosure, a wheelchair
user can conveniently fix a headrest to a wheelchair in use.
