Description

  The present invention relates to a vehicle door capable of a smooth getting-off operation by reducing the interference between the foot and the door when the passenger gets off.

  Conventionally, a door trim or the like provided on the side of the vehicle compartment of a vehicle door is provided with a door pocket or the like for accommodating a beverage bottle, a small luggage, or the like. For example, as in Patent Document 1, the door pocket is provided on the lower portion of the door trim below the door armrest. Further, as in Patent Document 2, the door pocket is formed by providing a bottom portion and an opposite wall portion in a recessed wall portion in which a door trim is recessed outward on the vehicle side.

  Further, the vehicle door is provided with a speaker accommodating portion for accommodating a speaker for outputting audio such as in-vehicle audio. Since the occupant does not touch the speaker to operate the speaker, the speaker accommodating portion is often provided on the lower side of the door trim which can not be reached by the occupant sitting on the seat.

  As described above, the door trim is formed to advance to the vehicle compartment side in order to provide an accommodation portion for luggage and the like and a speaker accommodation portion on the lower side thereof, so the thickness of the vehicle door increases and the vehicle door is opened. The opening on the side of the vehicle is narrow.

  When the passenger opens the vehicle door and gets off, the lower leg on the door side is first taken out of the vehicle, the foot is landed, and the upper body is moved. However, the opening on the side surface of the vehicle when the door is opened is narrowed due to the thickness of the door for the vehicle, so there is a possibility that the operation up to the landing of the foot may not be smooth.

  On the other hand, the movement to the landing of the foot at the time of getting off includes the rotational movement of the thigh. The inventor has found that the rotational movement of the thigh has a rotational angle range that is difficult to rotationally move. The rotation angle range corresponds to an operation in which the occupant takes the foot out of the vehicle beyond the side sill of the vehicle from the cabin. Therefore, it is difficult to perform the operation as intended by the occupant, so the side sill or the door trim easily interferes with the foot, and the occupant may not be able to get off smoothly.

  An object of the present invention is to provide a vehicle door capable of smoothly getting off.

  The invention according to claim 1 is a vehicle door having a front end portion hinged to a pillar portion of the vehicle so as to be able to open and close a side opening portion of the vehicle, and a housing portion at a lower portion on a vehicle compartment side. When a passenger of a standard size who sits on the seat section opens at the vehicle door and gets off with the hip point set at the center of the vehicle width direction at the rear of the seat section of the seat adjacent to the door When rotating the thighs of the lower limbs in order to take out the bent lower limbs on the vehicle door side out of the vehicle, the lower part of the vehicle door on the vehicle room side lower end does not interfere with the feet of the lower limbs It is characterized in that an interference reducing recess is provided which is recessed toward the vehicle outer side.

  According to the above configuration, when the passenger dismounts by opening the vehicle door having the hinged front end portion, the thigh of the lower leg on the vehicle door side is rotationally moved to the vehicle door side centering on the hip point Since the interference reducing recess is provided on the vehicle door so that a collision between the foot moving with the thigh and the vehicle door can be avoided when doing this, the interference between the vehicle door and the foot can be reduced. .

  According to a second aspect of the present invention, in the first aspect, the interference reducing recess has a predetermined intermediate opening degree when the rotation angle when the thigh is parallel to the front-rear direction of the vehicle is 0 °. It is characterized in that it is provided in a portion corresponding to a predetermined rotation angle range of the thigh with a center of at least 50 ° of the vehicle door.

  According to the above configuration, when the vehicle door is at the predetermined intermediate opening degree, the vehicle door corresponding to the predetermined rotation angle range of the thigh, centering at least 50 ° at which it is difficult to rotationally move the thigh Since the interference reducing recess is provided in the portion, the interference between the vehicle door and the foot can be reduced. In addition, since the capacity reduction of the housing portion due to the interference reducing recess is limited to the predetermined rotation angle range, the capacity reduction of the housing portion can be suppressed.

  The invention according to claim 3 is characterized in that, in claim 2, the interference reducing recess is provided such that a portion corresponding to the center of the rotation angle range is a top of a concave shape.

  According to the above configuration, the interference reduction recess is provided such that the portion corresponding to the angle at which the most thigh in the middle of the rotation angle range is difficult to rotationally move is the most recessed apex of the interference reduction recess. Interference between the vehicle door and the foot can be reduced.

  According to the door for a vehicle of the present invention, it is possible to smoothly get off the vehicle by reducing interference with the foot when the passenger gets off.

  As shown in FIG. 1 and FIG. 2, side openings 2 for getting passengers into and out of the vehicle 1 are respectively provided on the left and right side surfaces of the vehicle 1, and the side opening 2 can be opened and closed as a vehicle door. A seat right side door 3a, a front seat left side door 3b, a rear seat right side door 3c, and a rear seat left side door 3d are disposed. The vehicle 1 has a pair of left and right side sills 5 extending in the longitudinal direction at both lower end portions of the vehicle door in the vehicle width direction and a plurality of cross members (not shown) extending in the vehicle width direction and connecting the pair of side sills 5 And a floor panel (not shown) which is disposed so as to bridge between the pair of side sills 5 and which divides the vehicle compartment from the outside of the vehicle. A right front seat 6a, a left front seat 6b, and a rear seat 7 are disposed in the vehicle compartment, and an occupant can be seated on these seats. Since the vehicle 1 has a substantially symmetrical structure, the right side of the vehicle 1 will be described, and the description of the left side of the vehicle 1 will be omitted.

  A side opening 2 on the right side of the vehicle 1 includes a hinge pillar 10 (pillar portion) erected at a front end portion of the side sill 5, a front pillar 11 extending obliquely upward and rearward from an upper end portion of the hinge pillar 10, and a front pillar A roof side rail 12 extending rearward from the rear end portion of 11 and a rear pillar 13 erected at the rear end portion of the side sill 5 and connected to the rear end portion of the roof side rail 12 It is sectioned back and forth by a center pillar 14 which is erected and connected to an intermediate portion of the roof side rail 12.

  The front end portion of the front seat right side door 3a is hinged to the hinge pillar 10 (pillar portion), and the front compartment of the center pillar 14 can be opened and closed by pivoting about the axis of the hinge joint. In addition, a door checker 16 connected to the hinge pillar 10 is provided at the front end portion of the front seat right side door 3a so as to be able to be maintained at a predetermined intermediate opening degree or a full open position. A door locker 15 (see FIG. 3) which engages with a door striker (not shown) provided on the center pillar 14 at the rear end portion of the front seat right door 3a to keep the front seat right door 3a closed. Is provided. Similarly, the rear seat right side door 3c has its front end portion hinged to the center pillar 14 so that the rear compartment of the center pillar 14 can be opened and closed.

Next, the front door and the right door 3a will be described as an example of the vehicle door based on FIG. 3 and FIG.
The front seat right side door 3a has a main body portion 20 and a sash portion 21 on the upper side thereof, and a window glass 22 is disposed so as to be openable and closable in a window portion surrounded by the main body portion 20 and the sash portion 21. A door inner handle 23 for releasing the door lock by the door locker 15, an armrest 24, an operation unit 25 for opening and closing the window glass 22, etc. can be grasped for closing the door on the vehicle compartment side of the main body 20 A handle 26 and the like are provided, and these are disposed on the upper portion of the main body 20 so as to be easily operated by the occupant. Further, at the lower portion of the vehicle compartment side of the main body portion 20, a speaker accommodating portion 27 capable of accommodating the speaker 27a, a door pocket portion 28 capable of accommodating luggage such as a beverage bottle, and the like are provided.

  The main body 20 includes a door outer panel 31, a door inner panel 32 and a door trim 33 in this order from the vehicle outer side. The opening provided in the door inner panel 32 for work is covered with a panel member 32a. The door trim 33 is formed to extend from the door inner panel 32 to the vehicle compartment side, and a speaker housing portion 27 and a door pocket portion 28 are provided between the door inner panel 32 and the door trim 33.

  The speaker 27 a housed in the speaker housing portion 27 is mounted on the door inner panel 32, and the door trim 33 covers the vehicle cabin side. In a portion of the door trim 33 facing the speaker 27a, a plurality of holes are formed for passing the sound output from the speaker 27a. An opening may be formed in the portion of the door trim 33 facing the speaker 27a, and a mesh-like cover member may be disposed in the opening.

  The door pocket portion 28 includes a recessed portion 34 in which the door trim 33 is formed in a recessed shape on the door inner panel 32 side, and a wall portion 35 formed by advancing from the lower end portion of the door trim 33 to the vehicle compartment side and bending upward. The pocket-like member 36 is disposed between the two. The door pocket portion 28 can also be formed by attaching a member to be a bottom portion and a wall portion to the door trim 33 or integrally molding with the door trim 33. The lower end vicinity portion of the door inner panel 32 and the lower end vicinity portion of the door trim 33 are formed in a shape following the stepped shape of the side sill 5 when the front seat right side door 3a is closed.

Next, based on FIG. 5 and FIG. 6, the rotational movement of the thighs at the time of getting off will be described by taking the occupant of the right front seat 6a as an example.
An occupant of a standard size sitting on the seat portion 40 of the right front seat 6a takes out the bent right leg 41 on the front seat right door 3a side out of the vehicle when the front seat right door 3a is opened and dismounted. While lifting the thighs 42, they are rotationally moved outward of the vehicle. The foot 44, which is the ankle to tip part of the right lower leg 41, is connected to the thigh 42 via the lower thigh 43, and moves together with the rotational movement of the thigh 42. The front right-hand door 3a in the open state is farther from the side opening 2 on the rear side, and the space between the door trim 33 and the side sill 5 becomes wider.

  The rotational movement of the thighs 42 is performed with the hip point HP set at the center in the vehicle width direction at the rear of the seat portion 40 as the rotation center, and the thighs 42 are parallel to the longitudinal direction of the vehicle 1 in plan view The rotation angle θ is set to 0 °, and the entire foot portion 44 is moved to the outside of the side sill 5 until it can land. The standard physique is, for example, the average physique of an adult male, and the length of the thigh 42 (the length from the butt to the knee of the occupant in the sitting posture) is about 650 to 700 mm. In addition, the foot portion 44 may be internally rotated in the direction opposite to the rotational direction of the thigh portion 42 together with the lower leg portion 43, and the rotation angle θ of the thigh portion 42 at the time of landing may be made as compared Becomes smaller.

  At this time, although the thigh section 42 is rotationally moved within the movable range of the hip joint, when the joint passive resistance which is an index of movement difficulty with this hip joint is measured according to the getting-off operation, the joint passive resistance is increased along with the increase of the rotation angle θ. The value of will increase. Then, the value of the joint passive resistance peaks near the rotation angle θ = 50 °, and becomes larger than a predetermined comfort threshold L0 which does not cause difficulty in movement. When the thigh portion 42 is further rotationally moved, the space between the door trim 33 and the side sill 5 is enlarged, and interference between the door trim 33 and the foot portion 44 is less likely to occur. As a result, the occupant can move the thighs 42 downward or upward for rotational movement in a comfortable posture, so the value of the joint passive resistance decreases. As described above, the occupant feels the difficulty of rotational movement near the rotation angle θ = 50 ° where the value of the passive joint resistance becomes larger than the comfort threshold L0 when the thigh portion 42 is rotationally moved. Further, since it is difficult to rotationally move, the passenger can not rotationally move as intended, and the foot portion 44 and the door trim 33 may collide with or interfere with each other, which may hinder a smooth getting-off operation.

  Further, the degree of interference between the foot portion and the vehicle door at the time of getting off also varies depending on the opening degree of the vehicle door. For example, when the front seat right side door 3a is fully opened, the space between the side sill 5 and the door trim 33 is sufficiently large even at an opening narrowed due to the thickness of the front seat right side door 3a. Therefore, interference between the foot portion 44 moving with the rotational movement of the thigh portion 42 and the door trim 33 hardly occurs, but there are not many cases where the front seat right side door 3a and the like can be fully opened.

  On the other hand, when the vehicle is parked in a parking space having a general width (for example, 2300 mm), the predetermined intermediate opening maintained by the door checker 16 corresponds to the vehicle width of the vehicle 1 or the size of the front seat right door 3a. Accordingly, the opening degree is set so as not to collide with the parked vehicle in the adjacent parking space. The predetermined intermediate opening degree is set to, for example, 30 ° in the front right side door 3a and 35 ° in the rear right side door 3c, when the closed state of the vehicle door is 0 °. It is considered most likely that the occupant dismounts at this predetermined intermediate opening degree, and there is no interference between the door trim 33 and the thigh 42 due to the rotational movement of the thigh 42, but the interference between the foot 44 and the door trim 33 It is in the situation to occur.

  In order to reduce the interference between the foot 44 and the door trim 33, as shown in FIGS. 3 to 5, the vicinity of the lower end of the door trim 33 of the front right side door 3a corresponds to the lower end of the vehicle door Make the vehicle compartment side part of the door trim 33 advanced to the vehicle compartment side (wall part 35 of the door pocket part 28 and the part facing the speaker 27a of the speaker accommodation part 27) recessed in at least a part of The interference reducing recess 38 is provided. The interference reducing recess 38 is formed in a substantially arc shape having a concave top in the vertical direction of the door trim 33 and a substantially arc having a concave top in the door thickness direction from the door trim 33 toward the door inner panel 32. It is formed. The top of the interference reducing recess 38 in the vertical direction and the top in the thickness direction of the door coincide in position in the front-rear direction of the door.

  The interference reducing recess 38 is formed at a position corresponding to at least a predetermined rotation angle range of the thighs 42 when the front right side door 3a is at a predetermined middle opening degree. The predetermined rotation angle range is 45 ° to 55 ° including a range exceeding at least the comfort threshold L0 with the rotation angle θ = 50 ° of the thigh 42 at which the value peaks based on the passive joint resistance. The range is preset. The top of the concave is made to coincide with the position corresponding to the rotation angle θ = 50 ° of the thigh 42 at which the value of the passive joint resistance peaks.

The operation and effect of the present invention will be described.
For example, when the occupant of the right front seat 6a gets off, the thighs 42 of the bent right lower leg 41 on the front seat right door 3a side are rotationally moved toward the front seat right door 3a centering on the hip point HP. At this time, a part (for example, a toe portion) of the foot portion 44 is made to enter an interference reducing recess 38 formed in the vicinity of the lower end of the door trim 33 of the front seat right door 3a to reduce interference with the door trim 33. it can.

  In addition, when the front seat right side door 3a is set to a predetermined intermediate opening degree, at least 50 ° of a predetermined center of the thigh portion including a rotation angle range in which at least the thigh portion 42 of the door trim 33 is difficult to rotationally move. An interference reducing recess 38 is provided in a portion corresponding to the rotation angle range. Therefore, the interference between the door trim 33 and the foot 44 can be reduced in a rotation angle range in which the thigh 42 is difficult to rotationally move. In addition, since the capacity reduction of the speaker housing portion 27 and the door pocket portion 28 due to the interference reducing recess 38 is limited to the rotation angle range, the capacity reduction can be suppressed.

  Moreover, the interference reducing recess 38 is provided such that the portion corresponding to the center of the rotation angle range is the top of the concave shape. Therefore, it is possible to reduce the interference between the door trim 33 and the foot 44 by maximizing the accessible space of the foot 44 at a portion corresponding to the center of the rotation angle range where the thigh 42 is most difficult to rotationally move.

  Although the front seat right side door 3a has been described as an example, a recess corresponding to the interference reducing recess 38 can be provided in the rear seat right side door 3c as well. Furthermore, since the vehicle 1 has a symmetrical structure, similar recessed portions can be provided in the front left side door 3b and the rear left side door 3d, and the foot and the door trim of the occupant of the seat adjacent to these doors get off Smoother alighting operation is possible by reducing the interference.

  In the interference reducing recess 38, the contact portion of the door trim 33 with which the foot 44 abuts due to the movement of the foot 44 accompanying the rotational movement of the thigh 42 is recessed toward the door inner panel 32 by the pressure received from the foot 44. It may be configured to Interference between the foot 44 and the door trim 33 can be reduced, and the appearance can be improved because the concave shape can not be seen when there is no interference.

  In addition, those skilled in the art can carry out various modifications to the embodiment without departing from the spirit of the present invention, and the present invention also includes such modifications.
