[0035] The wheelchair 2 is provided with a cushion seat 34 having an attachment part 42 that allows the attachment position of a detachable cushion 44 to be changed. In this wheelchair 2, the attachment position of the detachable cushion 44 with respect to the cushion seat 34 can be changed.

[0036] In this wheelchair 2, it is preferable that the cushion sheet 34 is attached in such a way that hands can be inserted between the cushion sheet 34 and the back sheet 20 and waist sheet 22. This allows the caregiver to easily attach and detach the detachable cushion 44 to and from the attachment portion 42 while the user is seated. Also, the caregiver can easily change the position of the detachable cushion 44 while the user is seated. Furthermore, the caregiver can easily change the usage state of the detachable cushion 44 between the usage state in FIG. 4 and the usage state in FIG. 6.

[0037] In this wheelchair 2, attachment parts 42A and 42B are located on the side to the left of the center. Attachment parts 42D and 42E are located on the side to the right of the center. This allows the position at which the detachable cushion 44 supports the user to be adjusted in the left-right direction. Note that, here, attachment parts 42 are located at two or more different positions on both the left and right sides, but it is also possible to locate attachment parts 42 on either one. Furthermore, in this wheelchair 2, a pair of attachment belts 40 are arranged one above the other. This allows the position at which the detachable cushion 44 supports the user to be adjusted in the up-down direction as well.

[0038] The cushion sheet 34 is attached at a position that supports the back of the user. As shown in Figs. 7 to 9, the cushion sheet 34 can adjust the position and number of the detachable cushions 44 according to the body type and posture of the user. The cushion sheet 34 can adjust the position and number of the detachable cushions 44 while the user is seated. The cushion sheet 34 is suitable as a cushion that supports the back of the user. The use of the cushion sheet 34 is not limited to a cushion that supports the back of the user. The cushion sheet 32 ​​that supports the buttocks of the user and the cushion sheet 36 that supports the head of the user may have a structure similar to that of the cushion sheet 34. Although not shown, the wheelchair 2 may also have a cushion sheet that supports the legs of the user. The cushion sheet is attached to the foot leg support 12. The cushion sheet may have a structure similar to that of the cushion sheet 34. In the wheelchair 2, as shown in Fig. 2, the foot leg support 12 has a pad that supports the calves of the user. For example, a cushion sheet having a structure similar to that of the cushion sheet 34 may be attached to the pad. The cushion sheet may be one that supports a part of the user's legs like this pad, or one that supports the entire legs, or even one that covers the entire legs.

[0039] The removable cushion 44 has a bag 45 and a number of beads 46 housed in the bag 45. The beads 46 are movable within the bag 45. The removable cushion 44 can change its shape to suit the user's body type and support position. From this perspective, it is preferable that the removable cushion 44 has a number of beads 46 housed in the bag 45. The beads 46 are an example of grains filled in the removable cushion 44, and the grains are not limited to the beads 46. The removable cushion 44 may have a bag 45 and a flowable material housed in the bag 45. The removable cushion 44 may be an air cushion as long as it is shape-changeable. The removable cushion 44 is not limited to an air cushion, and may be filled with other gases, fluids, gels, etc.

[0040] In this wheelchair 2, the beads 46 are straw beads. The shape of the beads 46 is hollow cylindrical. The beads 46 are lightweight. Since the beads 46 are cylindrical, they can move easily within the bag 45. Since the beads 46 are hollow, they have excellent breathability. Furthermore, the bag 45 may be made of mesh (mesh weave).

[0041] In addition, the size and hardness of the straw beads can be selected. The removable cushion 44 filled with relatively large and hard straw beads is less likely to lose its shape. This removable cushion 44 easily supports the user even when the user's weight is applied to it. Furthermore, by adjusting the shape of the removable cushion 44 in advance, it is possible to properly support the user in various postures. On the other hand, the removable cushion 44 filled with relatively small straw beads easily deforms to correspond to the user's body when the user's weight is applied to it. The ease of deformation of the removable cushion 44 can be adjusted by filling it with straw beads according to the purpose.

[0042] The removable cushion 44 is easily foldable since it is divided into many sections 44B. From this viewpoint, it is preferable that the removable cushion 44 has two or more divided sections 44B.

[0043] In this removable cushion 44, the boundary 44A extends from one end to the other end in one direction. This boundary 44A makes it easy to fold the removable cushion 44 in half. It is preferable that this removable cushion 44 has the boundary 44A extending from one end to the other end of the bag 45 in one direction.

[0044] In this wheelchair 2, the attachment belt 40 forms the attachment portion 42. The attachment belt 40 is stretchable. The attachment belt 40 sandwiches the seat body 38 and the detachable cushion 44. The attachment belt 40 positions the detachable cushion 44 and also makes it easy to change or adjust the position of the detachable cushion 44. From this perspective, it is preferable that the attachment belt 40 is stretchable.

[0045] The attachment portion 42 is located on the underside 38B of the seat body 38. In this wheelchair 2, a caregiver can insert his or her hands between the attachment portion 42 and the back seat 20 and the waist seat 22. With the user in a seated position, the caregiver can attach or detach the detachable cushion 44 to or from the attachment portion 42. Also, with the user in a seated position, the caregiver can change the position of the detachable cushion 44. Furthermore, the caregiver can change the usage state of the detachable cushion 44 between the usage state in FIG. 4 and the usage state in FIG. 6.

[0046] Although the cushion seat 34 of the wheelchair 2 is provided with a pair of mounting belts 40, the number of mounting belts 40 is not limited to this. The number of mounting belts 40 may be one, or may be three or more.
