A vertical portion extending in the vertical direction; and a movable portion connected to an upper end of the vertical portion and rotatable about the vertical portion. The movable portion of the handrail has a wheelchair mounted in the wheelchair mounting space. When the rear seat is disposed in the wheelchair mounting space in a first state where the passenger is able to grip the seating position in front of the seating position of the passenger in the wheelchair mounted, It moves to the 2nd state located in the position which can be used as an armrest (armrest) of the passenger | crew who seated in, It is characterized by the above-mentioned.

  According to a second invention, in the first invention, the movable part of the handrail has an inclined part extending obliquely upward, and the movable part is in the first state when viewed from above. Is inclined in a direction toward the front side toward the vehicle interior side, and is positioned and fixedly held so as to be directed rearward in the second state.

  In a third invention, in the first or second invention, when the rear seat is disposed in the wheelchair mounting space, the lower end of the vertical portion is the vehicle width of the front and rear intermediate portion in the seat cushion of the rear seat. The vehicle is mounted on the rear side of the vehicle body opening portion where the occupant seated in the rear seat gets in and out at the direction side position.

  According to a fourth invention, in any one of the first to third inventions, the handrail includes a reinforcing portion that is connected to a distal end of the movable portion and extends downward.

  According to 1st invention, the handrail provided in the right-and-left side part of a wheelchair mounting space is located in the position which the passenger | crew can hold | grip the movable part ahead of a wheelchair passenger's seating position in a 1st state. It is like that. Therefore, the passenger seated in the wheelchair can grip the handrail with the arm naturally extended forward. Further, in the second state, the movable part of the handrail is located at a position where it can be used as an armrest for an occupant seated on the rear seat. Therefore, the comfort of the rear seat can be ensured.

  According to the second invention, in the first state, the movable part of the handrail is inclined and extended upward toward the vehicle interior side, and when viewed from above, the movable part of the handrail cooperates with the movable part of the other handrail. The movable parts on both sides are fixed and held so as to draw a square shape. Therefore, when the passenger in the wheelchair is large, the passenger can grip the portion on the high side on the front side of the movable part, and when the passenger on the wheelchair is small, grip the part on the low side on the rear side of the movable part. be able to. In other words, by adopting such a movable part inclined, even if the gripping position varies depending on the physique of the wheelchair passenger, the movable part is positioned at a position that is easy for the passenger to grip. The handrail can be gripped in an easy posture, and you can get on with peace of mind.

  Further, in the second state, the movable part of the handrail is inclined upward as it goes rearward, so that an occupant seated on the rear seat can easily use it as an armrest, and the comfort of the rear seat can be improved.

  According to the third invention, the vertical portion of the handrail is attached to the rear side of the vehicle body opening portion where the occupant seated in the rear seat gets on and off, so that the comfort of the rear seat is not disturbed. Can be secured.

  According to the fourth invention, since the reinforcing portion extending downward is connected to the tip of the movable portion, it is possible to prevent the movable portion from being deformed in the vertical direction when the vehicle body rolls over or falls due to a collision or the like. Excellent safety.

In embodiment of this invention, it is a rear side view of the welfare vehicle in a wheelchair-mountable state. It is a top view in FIG. In embodiment of this invention, it is an expansion perspective view of a rotation mechanism when a handrail is in a 1st state. FIG. 6 is a cross-sectional view taken along line AA in FIG. 5.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The following description of the preferred embodiments is merely exemplary in nature and is in no way intended to limit the invention, its application, or its application.

  In the following description, the state where the handrail 8 is held at the position shown in FIGS. 1 and 2 is the second state, and the state where the handrail 8 is held at the position shown in FIGS. 3 and 4 is the first state. . 1 to 4, the front direction of the vehicle is “front” or “front”, and the rear direction of the vehicle is “rear” or “rear”.

  1 and 2, reference numeral 1 denotes a welfare vehicle according to an embodiment of the present invention, and the welfare vehicle 1 has a rear seat 2 that can be folded forward in a vehicle interior. As shown in FIG. 1, the rear seat 2 arranged at the rear part of the welfare vehicle 1 includes a seat back 21 constituting a backrest part, a seat cushion 22 constituting a seating part, and a lower end part of the seat back 21 as a seat cushion. The support member 23 is connected to and supported by the rear end of the head 22 and the headrest 24 is detachably attached to the upper end of the seat back 21. The seat back 21 is supported by a hinge shaft (not shown) facing the support member 23 in the left-right direction so that the seat back 21 can be tilted in the front-rear direction.

  The floor panel 3 at the lower part of the vehicle interior is formed so that the rear side is gently inclined downward. Concave portions 31 are formed on both left and right sides of the vehicle on the floor panel 3, and a pair of brackets 4 are integrally provided in both concave portions 31, and the pipe-like leg members 5 that support the seat cushion 22 are mounted on the brackets 4. Is attached. The lower end (front end) of the leg member 5 is attached to the bracket 4 so as to be pivotable forward, and the upper portion of the leg member 5 is in contact with the lower surface 22a on the front side of the seat cushion 22 to support the seat cushion 22. Then, as will be described later, the rear seat 2 is folded forward by rotating the rear seat 2 forward with the lower end (front end) of the leg member 5 as a fulcrum in a state where the seat back 21 is tilted forward. A wheelchair mounting space S in which the wheelchair 90 can be mounted is formed in the space where the wheelchair 90 is located, and the wheelchair 90 is mounted in the wheelchair mounting space S.

  A first bulging portion 6 is formed to bulge toward the passenger compartment on both the left and right sides of the floor panel 3 and on both sides of the seat cushion 22. Further, a second bulging portion 7 is formed on the rear side of the first bulging portion 6 so as to bulge toward the passenger compartment.

  The first bulging portion 6 is provided with a pipe-like handrail 8 for the wheelchair passenger P to hold. The handrail 8 includes a vertical portion 9 having a lower end attached to the first bulging portion 6 and extending in the vertical direction, a movable portion 10 that is integrally connected to the upper end of the vertical portion 9 and is rotatable about the vertical portion 9, And a reinforcing portion 11 integrally formed at the distal end of the movable portion 10 and extending downward.

  The vertical portion 9 is attached at the lower end thereof at the intermediate position in the front-rear direction of the first bulging portion 6 and behind the vehicle body opening H and the rear door opening position Q indicated by a two-dot chain line in FIG. . Therefore, the vertical portion 9 does not get in the way when an occupant sitting on the rear seat 2 tries to get on and off through the vehicle body opening H.

  The movable portion 10 has a shaft portion 10a whose lower end is connected to the vertical portion 9 via a rotation mechanism K, which will be described later, and extends upward, and an inclined portion 10b that gently extends obliquely upward from the shaft portion 10a. As will be described later, the inclined portion 10b constitutes a gripping portion for the passenger P of the wheelchair 90 to grip.

  Since the reinforcing portion 11 is integrally formed at the tip of the movable portion 10 downward, when the vehicle body rolls over or falls due to a collision or the like, the vertical movable portion 10 can be prevented from being deformed. Excellent safety.

  A cap 12 for protecting the edge is attached to the tip of the reinforcing portion 11.

  The second bulging portion 7 is provided with a holding fitting 13 that is engaged with the engaging portion 23a of the support member 23 of the rear seat 2 and holds the rear seat 2 on the front side thereof.

  As shown in FIG. 2, in the state in which the rear seat 2 is arranged, the handrail 8 is extended and held in the front-rear direction so that the inclined portion 10 b of the movable portion 10 is positioned substantially parallel to the side surface of the rear seat 2. It is in a state. Therefore, an occupant seated on the rear seat 2 can use the inclined portion 10b of the movable portion 10 as an armrest. At that time, since the inclined portion 10b extends obliquely upward toward the rear, when the occupant of the rear seat 2 hangs his elbow, the occupant's arm gently inclines downward from the elbow toward the hand. The occupant can hang the elbow in a comfortable posture because the body does not have to bend greatly.

  Next, a state where a wheelchair can be mounted will be described with reference to FIGS. 3 and 4.

  As shown in FIG. 3, although details are omitted, the headrest 24 is pushed down until it abuts on the upper end of the seat back 21, and the seat back 21 is tilted forward and folded so as to be substantially parallel to the seat cushion 22. In addition, when the headrest 24 does not protrude largely upwards, it is also possible to fold the headrest 24 without pushing it down. In this state, the rear seat 2 is lifted forward by releasing the engagement with the holding bracket 13, so that the rear seat 2 rotates forward with the lower end of the leg member 5 as the center until the support member 23 comes to the upper side. And is held behind the driver seat and the passenger seat (not shown). Thus, the wheelchair mounting space S in which the wheelchair 90 can be mounted is formed in the space where the rear seat 2 is disposed. In addition, in the state which has arrange | positioned the rear seat 2, the predetermined distance is provided in the front-back direction between the lower end of the leg member 5 used as the rotation center of the rear seat 2, and the front edge 22b of the seat cushion 22. Therefore, in the state of FIG. 3 in which the rear seat 2 is rotated, a space is generated between the floor panel 3 and the front edge 22b of the seat cushion 22 (lower edge in the folded state of the rear seat 2). Since the headrest 24 can be accommodated in this space, the rear seat 2 can be folded and moved while the headrest 24 is attached, and the trouble of removing the headrest 24 can be saved.

  The handrail 8 rotates the movable portion 10 around the vertical portion 9 toward the front via a rotation mechanism K described later. If it does so, the movable part 10 will be hold | maintained by the rotation mechanism K mentioned later in the vehicle interior side and the 1st state located ahead with respect to the low side with the higher one of the inclination part 10b. That is, as shown in FIG. 4, the inclined portion 10 b of the handrail 8 on both sides as viewed from above is held at a position where it draws a letter C.

  When the wheelchair 90 on which the passenger P has boarded the wheelchair mounting space S is mounted, a state indicated by a two-dot chain line in FIGS. The mounted wheelchair 90 is slightly tilted backward by the inclination of the floor panel 3. The foot of the passenger P is located in a space (specifically, the rear side of the headrest 24) formed between the floor panel 3 and the front edge 22b of the seat cushion 22. That is, since the foot of the passenger P can enter the above-described space, the wheelchair 90 can be mounted as close to the front as possible, and the wheelchair 90 only needs to tilt slightly backward.

  In the handrail 8, the inclined portion 10b is positioned in front of the seating position and the elbow position of the passenger P. At this time, the height of the inclined portion 10 b of the handrail 8 on the tip side is approximately the same as the armrest 91 of the wheelchair 90. Therefore, as shown in FIG. 3 and FIG. 4, the occupant P can naturally extend the arm from the state where the armrest 91 is put on the elbow and can grip the inclined portion 10 b of the handrail 8. Further, the inclined portion 10b of the handrail 8 is held so that the shaft portion 10a side is low, the reinforcing portion 11 side is high, and the rear side is low in the first state. Therefore, for example, when the occupant P is large, it is possible to grip a portion on the higher side of the inclined portion 10b, and when the occupant P is small, it is possible to grip a portion on the lower side of the inclined portion 10b. Further, since the wheelchair 90 is slightly inclined backward, the inclined portion 10b is substantially parallel to the armrest 91. Therefore, even if the position where the occupant P grips can be changed, it is possible to grip the inclined portion 10b of the handrail 8 by naturally extending the arm from the state where the armrest 91 is put on the elbow. That is, even if the grip position of the handrail 8 changes depending on the physique or seating position of the passenger P, the handrail 8 can be gripped easily, so that the passenger P can feel safe and secure safety. Can do.

  Next, the structure for switching the handrail 8 between the first state and the second state and the operation state thereof will be described with reference to FIGS. 5 and 6.

  5 and 6 are enlarged views of the rotation mechanism K for switching the handrail 8 between the first state and the second state, in which the handrail 8 is held in the first state.

  As shown in FIGS. 5 and 6, the rotation mechanism K is integrally welded to the fixed member 16 integrally welded to the upper end of the vertical portion 9 of the handrail 8 and the lower portion of the shaft portion 10 a of the movable portion 10. And a bolt B and a nut N for tightening and fixing.

  The fixing member 16 includes a circular ring portion 16a having an opening at the center, and a fixing portion 16b formed by extending downward in the radial direction from one end of the ring portion 16a and then bending downward. The fixing portion 16b is provided with an insertion hole 16c for inserting the bolt B, and a nut N screwed with the bolt B is integrally fixed to the inner surface of the fixing portion 16b by welding or the like.

  The rotating member 17 has a flat surface portion 17a whose center is open, and a vertical surface portion 17b formed by bending downward from a peripheral outer edge of the flat surface portion, and is disposed so as to cover the fixing member 16 from above. . The vertical surface portion 17b includes a first notch 19 for holding the handrail 8 at the position of the first state and a second notch 20 for holding the handrail 8 at the position of the second state. It is provided in a state of being cut out in a bottomed shape from the top to the top.

  As shown in FIG. 6, the handrail 8 is tightened by the bolt B being screwed and fastened to the nut N through the notch 19 of the rotating member 17 and the insertion hole 16 c of the fixing member 16 in the first state. It is fixed. That is, since the rotating member 17 is welded to the movable portion 10 of the handrail 8, the movable portion 10 of the handrail 8 is fixed and held at the position of the first state without rotating.

  Next, the case where the handrail 8 is rotated from the first state to the second state will be described.

  First, the bolt B is loosened to release the fastening of the bolt B to the rotating member 17 so that the movable portion 10 can be moved upward. In this state, as shown by a two-dot chain line in FIG. 6, the movable portion 10 is lifted slightly upward until the first notch 19 of the rotating member 17 is completely removed from the bolt B. If it does so, it will be in the state which can rotate the movable part 10 in the state in which the notch 19 does not interfere with the volt | bolt B. In this state, the movable part 10 is rotated in the direction of the arrow shown in FIG. Then, the movable part 10 rotates substantially horizontally until the second notch 20 comes to the position of the bolt B. And when the 2nd notch 20 comes to the position of the volt | bolt B, by pushing down the movable part 10 to a position, the movable part 10 will move below and the 2nd notch 20 will engage with the volt | bolt B. . Since the second notch 20 is provided at a position where the handrail 8 is held in the second state, the rotating member 17 welded to the movable portion 10 is fixed by tightening the bolt B at the position, The movable part 10, that is, the handrail 8 is fixedly held at the position of the second state.

  As described above, the handrail 8 can be fixedly held by switching between the first state in which the passenger P of the wheelchair 90 can use and the second state in which the occupant seated on the rear seat 2 can use the handrail 8. it can.
