Description

Bus

Technical Field

The present invention relates to a bus on which passengers of a wheelchair can ride.

Background

Conventionally, there is known a bus (bus) in which a folding seat on the right side wall side where a landing door is not provided is folded, and a wheelchair in a forward posture is fixed in a space left by the folding seat in front of and behind the folding seat (for example, refer to japanese patent application laid-open No. 2015-85068). In addition, a bus has been known in which a wheelchair in a forward posture can be fixed in a space on the right side of the center portion of the vehicle cabin, and a wheelchair in a forward posture can be fixed in a space on the left and right side of the rear portion of the vehicle cabin (see, for example, japanese patent application laid-open No. 2001-47969).

In order to handle the opening/closing operation of the landing door provided between the second column and the third column on one side wall side and the emergency, an operator may be riding on an automated driving bus on which an unspecified plurality of passengers including passengers of a wheelchair are riding. The operator also performs a task of visually checking the front side of the automated guided bus, and therefore normally rides on the front side of the second column located on the front side of the landing door.

Therefore, an operation panel including an emergency brake button or the like to be operated by an operator in an emergency or the like is disposed on the front side of the second column. That is, at least the emergency brake button must be placed in a position where the operator can always press the emergency brake button, and the operator must ride in a position where the operator can always press the emergency brake button.

In general, the size of the landing door is increased in view of convenience. Thus, it is conceivable that: when a side collision occurs in another vehicle or the like toward the landing door, the landing door is greatly deformed toward the cabin interior. Therefore, it is desirable that the occupant of the wheelchair ride on the front side or the rear side of the door for riding on and off, that is, on the front side of the second column or on the rear side of the third column.

However, for example, when the passengers of the wheelchair ride side by side on the front side of the second column, it is difficult to leave a space for the operator to ride on the front side of the second column. Therefore, in this case, the operator must ride on the rear side of the second column and the front side of the third column (between the second column and the third column), and it is difficult to press the emergency brake button disposed on the front side of the second column.

Disclosure of Invention

Accordingly, an object of the present invention is to provide a bus capable of protecting a wheelchair occupant even when the vehicle is involved in a side collision and at least reducing an operator's contact failure with an emergency brake operating element.

In order to achieve the above object, a bus according to claim 1 of the present invention includes: a pair of left and right first pillars extending in the vehicle body up-down direction at the front portion of the vehicle body; a pair of left and right fourth pillars extending in the vehicle body up-down direction at the rear portion of the vehicle body; a pair of left and right second pillars extending in the vehicle body up-down direction on the vehicle body rear side of the first pillar and on the vehicle body front side of the fourth pillar; a pair of left and right third pillars extending in the vehicle body up-down direction on the vehicle body front side of the fourth pillar and on the vehicle body rear side of the second pillar; a landing door provided on one side wall of the vehicle body and between the second column and the third column; a front side wheelchair space that is set on a floor surface of a vehicle cabin so that at least a head of a wheelchair occupant is disposed in a region of the vehicle cabin surrounded by the first pair of left and right columns and the second pair of left and right columns in a plan view; a rear-side wheelchair space that is set on a floor surface of a vehicle cabin so that at least a head of a wheelchair occupant is disposed in a region of the vehicle cabin surrounded by the third column of the left-right pair and the fourth column of the left-right pair in a plan view; and an operation panel disposed on a vehicle body rear side of the first column and on a vehicle body front side of the second column, the operation panel including at least an emergency brake operation element, wherein the emergency brake operation element is configured to: the emergency brake operating element can be operated by an operator who is riding on the vehicle body rear side of the second column and the vehicle body front side of the third column.

According to the invention of claim 1, at least the head of a passenger riding in the wheelchair space provided on the floor surface of the vehicle cabin is disposed in the region of the vehicle cabin surrounded by the pair of left and right first pillars and the pair of left and right second pillars in plan view. In a plan view, at least the head of a passenger of the wheelchair riding in the rear wheel chair space provided on the floor surface of the vehicle cabin is disposed in a region of the vehicle cabin surrounded by the pair of left and right third pillars and the pair of left and right fourth pillars.

Here, the region of the vehicle cabin surrounded by the first pair of left and right columns and the second pair of left and right columns and the region of the vehicle cabin surrounded by the third pair of left and right columns and the fourth pair of left and right columns are high-strength regions. Therefore, even if the bus is collided with by the side, the passengers of the wheelchair having at least the head arranged in the high-strength region are not easily affected by the deformation of the vehicle body. That is, even when a bus is collided with at the side, passengers of wheelchairs that are getting on the bus are protected.

An operation panel having at least an emergency brake operation tool is disposed on the vehicle body rear side of the first column and on the vehicle body front side of the second column. The emergency brake operating element is configured to: the emergency brake operating element can be operated by an operator who is riding on the vehicle body rear side of the second column and the vehicle body front side of the third column. Therefore, even when a passenger gets in the wheelchair in the front wheelchair space, the operator can reduce the contact failure with the emergency brake operation tool in the emergency.

The term "bus" in the present invention refers to any bus that can carry and travel a plurality of passengers (including passengers in wheelchairs) irrespective of the presence or absence of payment of a freight, and a so-called travel service (Maas: mobility as a Service) vehicle, which is an example of an automated driving bus, is also included in the term "bus" in the present invention.

In addition, in the bus according to claim 2, in the bus according to claim 1, the operation panel is inclined toward the upper front side of the vehicle body in a side view.

According to the invention of claim 2, at least the operation panel having the emergency brake operation element is inclined toward the upper front side of the vehicle body in side view. Therefore, even in an emergency, an operator who rides on the vehicle body rear side of the second column and the vehicle body front side of the third column can easily operate the emergency brake operation tool.

Further, with the bus according to claim 3, in the bus according to claim 1 or 2, the interval in the vehicle body front-rear direction of the second column and the third column is wider than the interval in the vehicle body front-rear direction of the first column and the second column in side view, and the interval in the vehicle body front-rear direction of the second column and the third column is wider than the interval in the vehicle body front-rear direction of the third column and the fourth column in side view.

According to the invention of claim 3, the width of the landing door (landing entrance) provided between the second column and the third column in the vehicle body front-rear direction can be selected to be wide. Therefore, the passengers of the wheelchair can easily ride and descend, and the burden of the passengers of the wheelchair in riding and descending can be reduced.

The bus according to claim 4 is the bus according to any one of claims 1 to 3, including: and an engagement portion that is exposed from the floor surface on the vehicle body front side of the front end portion of the lifting door around the second column and the floor surface on the vehicle body rear side of the rear end portion of the lifting door around the third column in a plan view, and is engaged by an engaged portion provided at one end portion of a restraining strap for fixing the wheelchair to the vehicle body.

According to the invention of claim 4, the locking portion to be locked by the locked portion provided at the one end portion of the restraining belt for fixing the wheelchair to the vehicle body is exposed from the floor surface on the vehicle body front side of the front end portion of the door for raising and lowering around the second column and the floor surface on the vehicle body rear side of the rear end portion of the door for raising and lowering around the third column in plan view. Therefore, the locking portion does not interfere with the passenger, and the passenger does not trip over the locking portion. Further, an operator riding on the vehicle body rear side of the second column and the vehicle body front side of the third column can easily perform an operation of locking the locked portion of the tie down strap to the locking portion.

The bus according to claim 5 is the bus according to claim 4, wherein the locking portion is configured to lock the locked portion by inserting the locked portion from the vehicle width direction.

According to the invention described in claim 5, the locking portion is configured to lock the locked portion of the tie down strap by inserting the locked portion from the vehicle width direction. Therefore, for example, even if an inertial force toward the vehicle body front side acts on the wheelchair during emergency braking, the engaged portion of the restraining strap is less likely to come out of the engaged portion, and movement of the wheelchair toward the vehicle body front side is suppressed.

Effects of the invention

As described above, according to the present invention, even when a bus is collided with a side surface, a passenger who gets on a wheelchair of the bus can be protected, and at least a touch failure of an operator to an emergency brake operation tool can be reduced.

As shown in fig. 1 and 2, the bus 10 includes a door 20 for lifting and lowering, and the door 20 opens and closes a lifting and lowering port 16 provided between a second column 24 and a third column 26 on a left side wall (one side wall) 14 of the vehicle body 12. The landing door 20 is disposed so as to be separable at a central portion in the front-rear direction, and is configured such that a front half door 20F and a rear half door 20R slide toward the front side and the rear side, respectively, to open the landing door 16.

As shown in fig. 1, the distance D1 between the second column 24 and the third column 26 in the front-rear direction is wider than the maximum distance D2 between the first column 22 and the second column 24 in the front-rear direction in a side view, and the distance D1 between the second column 24 and the third column 26 in the front-rear direction is wider than the maximum distance D3 between the third column 26 and the fourth column 28 in the front-rear direction in a side view. That is, the width of the entrance 16 in the front-rear direction can be selected to be wide.

As shown in fig. 2, a front seat space 32 and a rear seat space 34 are provided on the front side and the rear side of the floor surface 30 of the cabin 18 of the bus 10, respectively. The floor surface 30 of the cabin 18 is an upper surface of a floor carpet (floor mat) laid on a floor panel 48 (see fig. 4) as a floor, and two rectangular frames having a longitudinal direction in the front-rear direction are shown in a left-right arrangement on the front side and the rear side of the upper surface of the floor carpet.

The regions surrounded by the front frames are respectively defined as front side wheel chair spaces 32, and the regions surrounded by the rear frames are respectively defined as rear side wheel chair spaces 34. Wheelchair marks (not shown) are shown in the substantially central portions of the front side wheelchair space 32 and the rear side wheelchair space 34, respectively, so that the riding position of the passenger P who is the wheelchair 90 is known at a glance.

As shown in fig. 2, at least the head (preferably the upper body) of the passenger P of the wheelchair 90 in the backward posture, which is fixed to the front side wheelchair space 32, is arranged in a region surrounded by the pair of left and right first pillars 22 and the pair of left and right second pillars 24 in a plan view. The region surrounded by the pair of left and right first posts 22 and the pair of left and right second posts 24 is a high-strength region of the vehicle cabin 18 in plan view.

As shown in fig. 2, at least the head (preferably the upper body) of the passenger P of the wheelchair 90 in the forward posture, which is fixed to the rear side wheelchair space 34, is arranged in a region surrounded by the pair of left and right third columns 26 and the pair of left and right fourth columns 28 in a plan view. The region surrounded by the pair of right and left third posts 26 and the pair of right and left fourth posts 28 is also a high-strength region of the vehicle cabin 18 in plan view.

As shown in fig. 2, a plurality of (for example, four) front seats 36 and rear seats 38, which can be used for a passenger (not shown) other than the passenger P of the wheelchair 90 to sit in a semi-standing position, are integrally arranged in the vehicle width direction on the front side of the front wheelchair space 32 and the rear side of the rear wheelchair space 34, respectively.

As shown in fig. 3, an auxiliary seat 40 is provided on the inner wall 24A of the second pillar 24 on the left side wall 14 side of the vehicle body 12, and the auxiliary seat 40 can be used for seating an operator Pt (see fig. 2) who gets on in order to handle the opening/closing operation of the landing door 20, emergency, and the like. The auxiliary seat 40 is rotatably supported at a lower end portion thereof so as to be capable of being unfolded and folded, and a folded state of the auxiliary seat 40 is shown in fig. 2 and 3. The armrest 41 is provided on the inner wall 24A of the second column 24 above the auxiliary seat 40.

As shown in fig. 2 and 3, an operation panel 44 is disposed between the first column 22 and the second column 24 (on the front side of the auxiliary seat 40) on the left side wall 14 side of the vehicle body 12, and the operation panel 44 has at least an emergency brake button 46 as an emergency brake operation member. The operation panel 44 is integrally connected to a front end portion of the support bracket 42 protruding from the left side wall 14, and the operation panel 44 is inclined forward and upward at a predetermined angle (angle with respect to the horizontal direction) in a side view.

As shown in fig. 4, a pair of left and right side reinforcements 50 extending in the front-rear direction are disposed below the floor panel 48 on both sides in the vehicle width direction. The pair of left and right side reinforcements 50 are connected in the vehicle width direction by a plurality of (four in the drawing) cross reinforcements.

That is, the pair of left and right side reinforcements 50 are connected in the vehicle width direction by the first, second, third, and fourth lateral reinforcements 51, 52, 53, 54 that are disposed at intervals in the front-rear direction in this order from the front.

The second lateral reinforcement 52 and the third lateral reinforcement 53 are connected at substantially the center in the vehicle width direction by a longitudinal reinforcement 55 extending in the front-rear direction. The front-rear direction substantially central portion of the vertical reinforcement 55 and the right side reinforcement 50 are connected by a lateral reinforcement 56 extending in the vehicle width direction.

The side reinforcement 50, the first lateral reinforcement 51, the second lateral reinforcement 52, the third lateral reinforcement 53, the fourth lateral reinforcement 54, the longitudinal reinforcement 55, and the lateral reinforcement 56 are each formed in a rectangular closed cross-sectional shape.

A pair of left and right front side reinforcements 57 extending in the front-rear direction are disposed on the front side of the inner sides of the pair of left and right side reinforcements 50 in the vehicle width direction. Further, a pair of left and right rear side reinforcements 58 extending in the front-rear direction are disposed on the rear side of the inner sides of the pair of left and right side reinforcements 50 in the vehicle width direction.

Each front-side stiffener 57 is formed in a rectangular closed cross-sectional shape, connecting the upper surface of the first lateral stiffener 51 with the upper surface of the second lateral stiffener 52 at least in the front-rear direction. Further, each rear-side stiffener 58 is formed in a rectangular closed cross-sectional shape, connecting the upper surface of the third lateral stiffener 53 with the upper surface of the fourth lateral stiffener 54 at least in the front-rear direction.

The front stiffener 57 and the rear stiffener 58 on the right side wall side where the passenger door 20 is not provided are integrally connected by an intermediate stiffener 59 extending in the front-rear direction. The intermediate side stiffener 59 is formed in a rectangular closed cross-sectional shape, and connects the upper surface of the second lateral stiffener 52, the upper surface of the lateral stiffener 56, and the upper surface of the third lateral stiffener 53 in the front-rear direction.

As shown in fig. 4, a holder 70 as a locking portion is provided in a part of the side reinforcement 50 disposed on the inner side in the vehicle width direction of the second column 24 and the inner side in the vehicle width direction of the third column 26, respectively, on the right side other than the second column 24 on which the auxiliary seat 40 is provided, and the holder 70 detachably locks a locked portion 82 provided on one end portion of a restraining belt 80 described later.

As shown in fig. 5, the holder 70 is attached to the upper surface of the base member 68 by screw fastening or the like, and the base member 68 is integrally provided on the upper surface of the bracket 60 (the body portion 62 described later). That is, as shown in fig. 8, the anchor 70 is fixed to the base member 68 by screws 75 aligned in the vehicle width direction. The bracket 60 is attached to the side stiffener 50 by welding or the like.

Specifically, as shown in fig. 5, the bracket 60 includes: a main body portion 62 having a rectangular closed cross-sectional shape in the vehicle width direction; a flat plate-shaped fitting portion 64 integrally formed to hang down from the front end lower portion and the rear end lower portion of the main body portion 62; and a rectangular flat plate-like base member 68 integrally provided on the upper surface of the main body 62 at a substantially central portion in the longitudinal direction. A substantially rectangular cutout 66 is formed in the lower portion of each fitting portion 64 so as to be fitted to the side stiffener 50 from above.

Therefore, when the bracket 60 disposed on the inner side of the left third pillar 26 in the vehicle width direction is described as an example, as shown in fig. 6 and 7, the cutout 66 formed in the fitting portion 64 is fitted to the left side reinforcing member 50 from above. The peripheral edge portion of the cutout portion 66 is joined to the upper surface and the side surface of the side reinforcement 50 by welding or the like, and the end portion 62A on the vehicle width direction inner side of the main body portion 62 is joined to the side surface of the left rear side reinforcement 58 by welding or the like.

Thereby, the bracket 60 is fixed to the left side stiffener 50 and the left rear stiffener 58. At this time, the configuration is as follows: the upper and lower surfaces of the main body portion 62 of the bracket 60 become coplanar with the upper and lower surfaces of the left rear reinforcement 58. That is, the main body 62 of each bracket 60 is formed with the same thickness as the left and right rear side reinforcements 58 and the right front side reinforcements 57.

Further, since the auxiliary seat 40 is provided on the left second column 24, the auxiliary seat 40 extends inward in the vehicle width direction (upper portion of the left side reinforcement 50). Therefore, the bracket 60 having the holder 70 cannot be provided on the left side stiffener 50. Therefore, another bracket (not shown) having the anchor 70 is mounted on a part of the left front stiffener 57 on the vehicle width direction inner side of the left second column 24.

Further, as shown in fig. 9, the holder 70 is formed to be exposed from the bottom plate surface 30. That is, a hole (not shown) for exposing the holder 70 is formed in the bottom plate surface 30. As shown in fig. 2 and 9, the holder 70 is disposed at a position as close as possible to the virtual line K4 (a position as close as possible to the operator Pt on the foot rest 92 side on the front side of the wheelchair 90) at a position surrounded by the virtual line K1, the virtual line K2, and the virtual line K3.

The virtual line K1 shows a range that is obtained by the hand of the operator Pt riding between the second column 24 and the third column 26 (on the center side of the vehicle cabin 18), and the range in the vehicle width direction is a range from one end to the other end of the vehicle body 12 in the vehicle width direction. The range in the front-rear direction is a range from a portion extending forward by a distance X from the tip end portion of the foot rest 92 of the wheelchair 90 that rides in the front-side wheelchair space 32 to a portion extending rearward by a distance X from the tip end portion of the foot rest 92 of the wheelchair 90 that rides in the rear-side wheelchair space 34. The distance X is a range easily reached by the hand of the operator Pt, and is, for example, x=500 mm.

The virtual line K2 indicates the periphery of the second column 24 and the periphery of the third column 26 (also including a plurality of not-shown deployable and stowable seats disposed between the right-side-wall-side second column 24 and the third column 26) where passengers other than the passenger P of the wheelchair 90 cannot stumble.

The virtual line K3 indicates a range in which the hands of the passenger P riding in each wheelchair 90 in the front side wheelchair space 32 and the rear side wheelchair space 34 can be obtained. Specifically, the range is within 600mm from the elbow of the passenger P of each wheelchair 90 in plan view and within approximately 90 degrees from the front side to the side of the passenger P.

The virtual line K4 represents a straight line extending in the vehicle width direction and passing through the front end surface and the rear end surface of the passenger door 20. The front-rear direction inner side of the virtual line K4 is a turning region in which the passenger P of the wheelchair 90 enters the passenger door 20, which is deformed at the time of a side collision, so that the passenger P can smoothly ride on and off the passenger door 20 in a short time. Therefore, the holder 70 is not set on the inner side in the front-rear direction of the virtual line K4.

As shown in fig. 2 and 9, a restraining belt 80 is attached to a wheelchair 90 that rides in the front side wheelchair space 32 and the rear side wheelchair space 34, respectively. The engaged portion 82 engaged with the holder 70 is provided at one end portion of the restraining belt 80, and the hook 78 engaged with the frame 96 or the leg rest 94 of the wheelchair 90 is provided at the other end portion of the restraining belt 80. A front wheel 98 is provided at the lower end of the frame 96.

As shown in fig. 10, the holder 70 has: a disk-shaped main body 72; front-side extension portions 74 extending from a front-side peripheral edge portion of the main body portion 72 so that a vehicle-width-direction central portion extends upward and rearward from vehicle-width-direction both end portions; and a rear extension 76 extending from a rear peripheral edge portion of the main body 72 to extend upward and forward from both ends in the vehicle width direction. As described above, the holder 70 is fixed to the base member 68 by the screw 75.

The engaged portion 82 includes: a main body 84; a columnar rod 86 provided in a central portion of the main body 84 so as to be movable in the up-down direction; a disk-shaped pressing portion 88 coaxially and integrally provided with the lower end portion of the lever portion 86; and a coil spring (not shown) provided between the main body 84 and the lever 86 to urge the pressing portion 88 upward.

Further, a pair of left and right engaging portions 85 formed in a flat plate shape are integrally formed on the lower surface of the main body 84, and the engaging portions 85 are formed in the thickness direction of the engaging portions 85 in the vehicle width direction, and the pressing portions 88 can be accommodated between the engaging portions 85. That is, the interval between the pair of left and right engaging portions 85 is set to be larger than the outer diameter of the pressing portion 88. A ring 87 is provided on the upper portion of the rod 86, and one end portion of the tie strap 80 is fitted to the ring 87 so as to pass through the ring 87.

With the above-described configuration, the engaged portion 82 of the binding band 80 is detachably engaged with the holder 70 as follows. That is, as shown in fig. 10 a, in a state where the pressing portion 86 is pressed downward against the urging force of the coil spring, the pressing portion 88 is inserted into a gap (insertion port) between the main body portion 72 of the retainer 70 and the front-side projecting portion 74 and the rear-side projecting portion 76 from the inside or outside in the vehicle width direction. Then, the pressing down of the lever 86 is released at the central portion of the holder 70.

As a result, as shown in fig. 10 (B), the engaging portions 85 engage (enter) both the left and right sides of the front-side projecting portion 74 and the rear-side projecting portion 76, and the upper end portions of the front-side projecting portion 74 and the rear-side projecting portion 76 are sandwiched between the upper surface of the pressing portion 88 and the lower surface of the main body portion 84 by the urging force of the coil spring. Thus, the engaged portion 82 of the binding band 80 is engaged with the holder 70 in a state in which the movement thereof is restricted up and down, front and back, and left and right.

When the engaged portion 82 of the binding band 80 is detached from the holder 70, the lever portion 86 is pressed downward against the urging force of the coil spring. In this state, the pressing portion 88 is pulled out from the gap between the main body portion 72 of the holder 70 and the front and rear protruding portions 74 and 76.

Further, the bus 10 in the present embodiment is assumed to travel in a special section at a speed of 20km or less. Therefore, when the bus 10 applies the emergency brake, the passenger P of the wheelchair 90 may grasp the armrest 41, and even in the case where the armrest 41 cannot be grasped, it is sufficient that each wheelchair 90 has one restraining strap 80 for fixing the wheelchair 90 to the vehicle body 12.

Next, the operation of the bus 10 configured as described above will be described.

As shown in fig. 2, at least the head (preferably the upper body) of the passenger P riding in the wheelchair 90 set in the front side wheelchair space 32 of the floor surface 30 in a backward posture is located in a high-strength region of the cabin 18 surrounded by the pair of left and right first pillars 22 and the pair of left and right second pillars 24.

Similarly, at least the head (preferably the upper body) of the passenger P riding in the wheelchair 90 provided in the rear wheel chair space 34 of the floor surface 30 in the forward posture is located in the high-strength region of the cabin 18 surrounded by the pair of left and right third pillars 26 and the pair of left and right fourth pillars 28.

Therefore, the passengers P of the wheelchairs 90 respectively riding in the front side wheelchairs 32 and the rear side wheelchairs 34 are less susceptible to deformation of the vehicle body 12 (the landing doors 20) at the time of a side collision, for example. That is, even when the bus 10 is collided with, for example, another vehicle (not shown), the passenger P of the wheelchair 90 on the bus 10 can be protected.

As shown in fig. 1, the maximum distance D2 between the first column 22 and the second column 24 in the front-rear direction is smaller than the distance D1 between the second column 24 and the third column 26 in the front-rear direction in a side view, and the maximum distance D3 between the third column 26 and the fourth column 28 in the front-rear direction is smaller than the distance D1 between the second column 24 and the third column 26 in the front-rear direction in a side view. Therefore, the region of the vehicle cabin 18 surrounded by the first pair of left and right columns 22 and the second pair of left and right columns 24 and the region of the vehicle cabin 18 surrounded by the third pair of left and right columns 26 and the fourth pair of left and right columns 28 can be made to be regions of higher strength, respectively.

In addition, conversely, the interval D1 in the front-rear direction of the second column 24 and the third column 26 is wider than the maximum interval D2 in the front-rear direction of the first column 22 and the second column 24 in side view, and the interval D1 in the front-rear direction of the second column 24 and the third column 26 is wider than the maximum interval D3 in the front-rear direction of the third column 26 and the fourth column 28 in side view. That is, the width of the entrance 16 provided between the second column 24 and the third column 26 in the front-rear direction is wide. Therefore, the passenger P of the wheelchair 90 can easily ride on and off the bus 10, and the load on the passenger P of the wheelchair 90 can be reduced during the ride.

Further, when the passenger P of the wheelchair 90 rides in the front side wheelchair space 32 in the backward posture, the following advantage is obtained. That is, when the passenger gets out of the boarding/disembarking port 16 provided in the bus 10, not only the passenger P of the wheelchair 90 riding in the forward posture in the rear side wheelchair space 34 can operate the wheelchair 90 in the forward posture, but also the passenger P of the wheelchair 90 riding in the rearward posture in the front side wheelchair space 32 can operate the wheelchair 90 in the forward posture. Therefore, the convenience of the bus 10 for the passenger P of the wheelchair 90 can be improved.

In this manner, when the passenger P of the wheelchair 90 rides on both the front side wheelchair spaces 32 set on the left and right sides, it is difficult for the operator Pt to ride between the first column 22 and the second column 24. Therefore, the operator Pt must ride between the second column 24 and the third column 26 in a standing posture (the rear side of the second column 24 and the front side of the third column 26) (refer to fig. 2).

Here, as in the bus 100 of the comparative example shown in fig. 11, if the operation panel 44 is disposed at the same level as the support bracket 42, it is difficult for the operator Pt (see fig. 2) riding between the second column 24 and the third column 26 to press the emergency brake button 46 provided on the operation panel 44 (it is difficult for the hand to reach the emergency brake button 46).

However, in the bus 10 of the present embodiment, as shown in fig. 3, the operation panel 44 is disposed so as to be inclined upward and forward with respect to the support bracket 42. Therefore, even the operator Pt riding between the second column 24 and the third column 26 can easily press the emergency brake button 46 provided on the operation panel 44 (the operator can easily reach the emergency brake button 46).

As described above, according to the present embodiment, the touch failure of the emergency brake button 46 by the operator Pt can be reduced in the event of an emergency. Further, the touch defect can be reduced by a simple configuration in which the operation panel 44 is tilted forward and upward with respect to the support bracket 42.

In this way, when the operator Pt gets on the space between the second column 24 and the third column 26, even the left second column 24 provided with the auxiliary seat 40 can be exposed from the optimal position of the peripheral bottom plate surface 30, similarly to the right second column 24 and the left and right third columns 26.

That is, the anchor 70 can be exposed from the optimal position of the floor surface 30 on the front side of the front end portion of the door 20 around the second column 24 and the floor surface 30 on the rear side of the rear end portion of the door 20 around the third column 26, in other words, the anchor 70 can be exposed from the position of the floor surface 30 surrounded by the virtual line K1, the virtual line K2, and the virtual line K3 and as close to the virtual line K4 as possible.

Therefore, the holder 70 does not interfere with passengers other than the passenger P of the wheelchair 90, nor does the passengers other than the passenger P of the wheelchair 90 stumble over the holder 70. Further, the operator Pt riding between the second column 24 and the third column 26 can easily perform the operation of locking the locked portion 82 of the tie down strap 80 to the anchor 70.

In particular, as shown in fig. 8, the pressing portion 88 (see fig. 10) is inserted in the vehicle width direction into the gap (insertion opening) between the main body portion 72 of the holder 70 and the front side protruding portion 74 and the rear side protruding portion 76. That is, the engaged portion 82 of the tie down strap 80 is inserted into the gap (insertion opening) of the anchor 70 from the inside or outside in the vehicle width direction.

Therefore, the operator Pt can more easily perform the operation of locking the locked portion 82 of the tie down strap 80 to the anchor 70. In addition, each wheelchair 90 is provided with one binding belt 80, so that the working time can be shortened. For example, when emergency braking is applied to the bus 10, the engaged portion 82 of the restraining strap 80 is less likely to come out of the holder 70 even if an inertial force directed to the front side acts on the wheelchair 90.

That is, even if an inertial force directed to the front side acts on the wheelchair 90, the movement of the wheelchair 90 to the front side can be suppressed or prevented by the restraining belt 80 (for example, in the case of a passenger of the backward wheelchair 90 riding in the front side wheelchair space 32, the front wheels 98 of the wheelchair 90 are lifted off the ground).

As shown in fig. 8, the gap (insertion port) between the main body 72 of the anchor 70 and the front and rear protruding portions 74 and 76 is opened in the vehicle width direction, so that the screws 75 are assembled so as to be aligned in the vehicle width direction. Therefore, compared to a configuration in which the screws 75 are assembled so as to be aligned in the front-rear direction, the width W of the base member 68 in the front-rear direction does not need to be selected to be wider for the strength of the assembly screws 75, and the width W of the base member 68 in the front-rear direction can be shortened. This can reduce the weight of the bracket 60.

Further, around the second column 24 and around the third column 26, side reinforcements 50, front reinforcements 57, and rear reinforcements 58 to which the first lateral reinforcement 51, the second lateral reinforcement 52, the third lateral reinforcement 53, and the fourth lateral reinforcement 54 are connected are arranged, so that the reinforcements are densely packed. Therefore, the strength of the portion to which the bracket 60 is fixed can be sufficiently ensured.

While the bus (bus) 10 of the present embodiment has been described above with reference to the drawings, the bus (bus) 10 of the present embodiment is not limited to the illustrated contents, and may be appropriately modified in design within the scope of the present invention. For example, the operation panel 44 may be connected to the front end portion of the support bracket 42 so as to be adjustable in angle.

The configuration in which the operator Pt can operate the emergency brake button 46 disposed between the first column 22 and the second column 24 even when the operator Pt is located between the second column 24 and the third column 26 is not limited to the configuration in which the operation panel 44 having the emergency brake button 46 is disposed so as to be inclined toward the front upper side at a predetermined angle.

In addition, the front seat 36 and the rear seat 38 may also be configured to be capable of deployment and stowage. That is, it may also be configured to: by setting the front seat 36 and the rear seat 38 to the stowable posture, the front side seat space 32 and the rear side seat space 34, respectively, are reserved for the occupant P of the wheelchair 90 to ride on.
