[0008] [Figure 1] 1 is a diagram showing the configuration of a vehicle equipped with a wheelchair support device according to an embodiment of the present invention; [Figure 2] 10A and 10B are diagrams for explaining the operation of the wheelchair supporting device of the embodiment. [Figure 3] FIG. 3(a) is a diagram showing the configuration of a wheelchair supporting device of a first modified example, and FIG. 3(b) is a diagram showing the configuration of a wheelchair supporting device of a second modified example. DETAILED DESCRIPTION OF THE INVENTION
[0009] 1 is a diagram showing the configuration of a vehicle 10 equipped with a wheelchair support device 1 of the embodiment. The wheelchair support device 1 includes a back door 12, a belt 14, and a retractor 18. The vehicle 10 may be capable of autonomous driving, and may have the functions of following a preceding vehicle and maintaining travel within a lane.
[0010] The vehicle 10 has a rear luggage compartment 24 at the rear of the vehicle compartment for placing a wheelchair, and the wheelchair carrying a wheelchair user can be carried into the rear luggage compartment 24 from the rear of the vehicle. When the wheelchair carrying a wheelchair user is carried into the rear luggage compartment 24, the wheelchair support device 1 supports the wheelchair with a belt 14 to stabilize it. The wheelchair support device 1 also supports the wheelchair carrying a wheelchair user inside the vehicle 10.
[0011] The back door 12 is rotatably mounted on the vehicle 10 by a hinge mounted on the ceiling side of the vehicle 10, and the rotational movement allows the opening at the rear of the vehicle to be opened and closed. An engaging portion 12a is provided on the inside of the back door 12 at the tip side of the back door 12. The engaging portion 12a is formed, for example, in a hook shape. The back door 12 can be in a closed state in which the opening at the rear of the vehicle is closed, and in an open state in which the back door 12 is rotated from the closed state to open the opening.
[0012] The retractor 18 is provided under the rear seat 16 and is capable of retracting / unreeling the belt 14. The retractor 18 may be capable of retracting the belt 14 electrically or by a spring. When the retractor 18 retracts the belt 14 electrically, the wheelchair on which the belt 14 is hooked may be carried into the rear luggage compartment 24. The retractor 18 also has a mechanism for locking the retraction and unreeling of the belt 14. A retractor 18 may be provided for each belt 14. The retractor 18 is disposed forward of the rear luggage compartment 24.
[0013] A pair of belts 14 are provided, extending from a retractor 18 toward the back door 12 at the rear of the vehicle. One end of the belt 14 is provided with a locking portion 14a, which is releasably locked to a locking portion 12a of the back door 12. The locking portion 14a is, for example, a hook, and is hooked onto the locking portion 12a. The locking portion 12a and the locking portion 14a may be electromagnetically locked together. The other end of the belt 14 is fixed to the retractor 18 inside the vehicle cabin.
[0014] The ramp plate 20 is disposed so as to stand on the back door 12 side, and is rotatably mounted by a hinge located on the floor of the luggage compartment. When the back door 12 is in the open position, the ramp plate 20 rotates so as to fall outside the vehicle and stops when it hits the road surface. The ramp plate 20 rotates between a closed position where it is housed inside the vehicle compartment and an open position where it is protruded outside the vehicle. In the open position, the ramp plate 20 functions as a passageway for carrying a wheelchair into the rear luggage compartment 24.
[0015] The side bars 22 are arranged upright on both sides of the slope plate 20 and are rotatable by hinges located on the floor of the luggage compartment. The side bars 22 can be rotated to take a closed state in which they are housed inside the vehicle compartment and an open state in which they are extended outside the vehicle.
[0016] 2A to 2D are diagrams for explaining the operation of the wheelchair support device 1 of the embodiment. Figures 2A to 2D sequentially show the operation when a wheelchair 26 is carried into the rear luggage compartment 24 using the wheelchair support device 1.
[0017] As shown in Fig. 2(a), the belt 14 is arranged along the luggage compartment floor 10a of the rear luggage compartment 24, and the locking portion 14a is locked to a locked portion 12a on the leading end side (lower end side) of the back door 12. When the back door 12 is closed, the locking portion 14a of the belt 14 is positioned so as to be accommodated within the vehicle interior.
[0018] 2(b), when the back door 12 is rotated from the closed state to the open state, the belt 14 is unwound from the retractor 18 in accordance with the rotation of the back door 12, and the engaging portion 14a is exposed to the outside of the vehicle at the rear of the vehicle. In this way, the opening movement of the back door 12 allows the belt 14 to be pulled out of the vehicle.
[0019] As shown in FIG. 2(c), the ramp plate 20 rotates from the closed state to the open state where it is protruding from the vehicle. The ramp plate 20 forms a passageway connecting the road surface and the rear luggage compartment 24. The ramp plate 20 may be rotated electrically or manually. The ramp plate 20 may be foldable, and is in a state where two plates are stacked on top of each other in the closed state.
[0020] As shown in FIG. 2(d), the caregiver releases the engaging portion 14a from the engaged portion 12a and hooks it onto the wheelchair 26. This is convenient because the caregiver does not need to leave the wheelchair user behind and enter the rear luggage compartment 24 to retrieve the belt 14 after setting the wheelchair at the rear of the vehicle. The wheelchair is supported by the belt 14, allowing it to move stably when climbing the ramp 20. In addition, the caregiver can activate the retraction device 18 to retract the wheelchair, allowing it to be pulled up.
[0021] The belt 14 remains engaged even after the wheelchair 26 is placed in the rear luggage compartment 24, and continues to support the wheelchair 26. The wheelchair 26 is also supported by the belt 14 when getting out of the vehicle 10.
[0022] Figure 3(a) is a diagram showing the configuration of a wheelchair support device of a first modified example, and Figure 3(b) is a diagram showing the configuration of a wheelchair support device of a second modified example. The wheelchair support devices shown in Figures 3(a) and 3(b) have different belt fastening positions compared to the wheelchair support device 1 shown in Figure 1.
[0023] In the wheelchair support device shown in Fig. 3(a), a locking portion 114a located at one end of a belt 114 is locked to a locked portion 120a of a slope plate 120. In the closed state shown by the dashed line in Fig. 3(a), the slope plate 120 is positioned so that the locking portion 114a of the belt 114 is positioned inside the vehicle cabin.
[0024] When the ramp plate 120 rotates from the closed state to the open state, the engaging portion 114a of the belt 114 follows the rotation of the ramp plate 120 and is exposed to the outside of the vehicle at the rear of the passenger compartment. This allows the caregiver to remove the engaging portion 114a from the engaged portion 120a and easily engage the belt 114 with the wheelchair. The other end of the belt 114 is fixed to the reel device 18.
[0025] In the wheelchair support device shown in Fig. 3(b), a locking portion 214a located at one end of a belt 214 is locked to a locked portion 222a of a side bar 222. In the closed state shown by the dashed line in Fig. 3(b), the side bar 222 is positioned so that the locking portion 214a of the belt 214 is disposed inside the vehicle cabin.
[0026] When the side bar 222 rotates from the closed state to the open state, the engaging portion 214a of the belt 214 is exposed to the outside of the vehicle at the rear of the vehicle compartment following the rotation of the side bar 222. This allows the caregiver to remove the engaging portion 214a from the engaged portion 222a and easily engage it with the wheelchair.
[0027] The back door 12 shown in Fig. 1, the slope plate 120 shown in Fig. 3(a), and the side bar 222 shown in Fig. 3(b) function as a rotation device provided in the vehicle 10. This rotation device rotates from a closed state to an open state, thereby exposing one end of the belt 14 to the outside of the vehicle at the rear of the passenger compartment.
[0028] The present disclosure has been described above based on examples. The present disclosure is not limited to the above examples, and various modifications such as design changes may be made based on the knowledge of those skilled in the art. [Explanation of symbols]
