Description

  The present invention relates to a structure for preventing a sliding door from being caught.

  2. Description of the Related Art Some vehicles, for example automobiles such as a one-box car, use a slide door to open and close a side opening formed on the side of a vehicle body for getting on and off a passenger in a rear seat. The sliding door is displaced from the closed position where the side opening is closed to the outer side in the vehicle width direction and then rearward along the outer surface of the vehicle body, thereby opening the side opening. It is assumed to be a position. Some of the sliding doors are electrically operated to open and close using the driving force of the motor.

  When the slide door is changed from the closed position to the open position, a gap is formed in the vehicle width direction between the inner side surface of the slide door in the vehicle width direction and the rear edge of the side opening. Become. Patent Document 1 discloses that a pressure-sensitive sensor is provided on the inner side surface of the sliding door in the vehicle width direction, and a load in the vehicle width direction that is generated when a foreign object is caught in the gap is detected by the pressure sensor. Has been. Japanese Patent Application Laid-Open No. H10-228688 also discloses that when the pinching of a foreign object is detected, driving of the electric slide door is stopped or the slide door is driven to be reversed in a direction in which the pinching is released. Further, Patent Document 2 discloses a device that detects a foreign object sandwiched by a pressure sensor provided at a front edge portion of a slide door when the slide door is displaced from an open position to a closed position ( Detection of pinching between the sliding door and the front edge of the side opening).

  In Patent Document 3, an armrest is provided on the inner side surface in the vehicle width direction of the slide door, and the armrest is located outward in the vehicle width direction with respect to the use position in addition to the use position protruding inward in the vehicle width direction. A storage door that is retracted to the side and can take a storage position that is substantially flush with the inner side surface in the vehicle width direction of the slide door is disclosed. Patent Document 3 discloses that when the sliding door in the closed position is opened, the armrest is automatically set to the storage position in conjunction with the movement of the sliding door toward the open position. However, the technique disclosed in Patent Document 3 is a technique for preventing the armrest from interfering with the vehicle body outer panel located behind the side opening when the slide door is opened. The problem of pinching is not recognized at all.

JP 2007-56522 A Japanese Patent Laid-Open No. 11-182136 Japanese Utility Model Publication No. 3-15369

  The techniques described in Patent Document 1 and Patent Document 2 described above detect foreign object pinching, and do not prevent foreign object pinching itself. In particular, when an armrest is provided on the slide door, the slide door is moved from the closed position to the open position in a state where an object (foreign matter) is placed on the armrest (for example, a state where an occupant's arm is placed). When driven, the problem of pinching is likely to occur.

  The present invention has been made in view of the above circumstances, and its purpose is to provide a space between the sliding door and the rear edge of the side opening when the sliding door is displaced from the closed position to the open position. It is an object of the present invention to provide a sliding door pinching prevention structure that can prevent a foreign matter from being caught in a gap formed in the sliding door.

In order to achieve the above object, the following solution is adopted in the present invention. That is, as described in claim 1 in the claims,
A closed position that covers the side opening formed on the side surface of the vehicle body, and the side opening by being moved rearward along the vehicle body outer surface after being displaced from the closed position outward in the vehicle width direction. An open position, a sliding door adapted to be able to take,
Drive means for driving the sliding door between the closed position and the open position;
Drive control means for controlling the drive of the drive means;
A use position provided on the inner side in the vehicle width direction of the slide door and protruding toward the inner side in the vehicle width direction and a storage position retracted outward from the use position in the vehicle width direction can be taken. Armrests made of,
Use state detecting means for detecting that the armrest is in the use position;
With
The drive control means is set to prohibit the drive means from driving the slide door toward the open position when the use state detection means detects that the armrest is in the use position. Being
It is like that.

  According to the above solution, when the armrest is in the use position, there is a high possibility that a foreign object such as an occupant's arm is placed on the armrest. In such a case, the armrest is moved to the open position. Therefore, the pinching is prevented from occurring without fail. Further, since the slide door is driven toward the open position with the armrest in the storage position, the displacement in the vehicle width direction outward side required when the slide door is opened from the closed position is minimized. This is also preferable. Furthermore, a passenger seated in a seat located on the side of the sliding door is disturbed by the armrest by resting the arm using the armrest that is in the use position and by setting the armrest to the storage position. It is possible to freely select a mode in which the passenger compartment is used in a state where the passenger compartment is widened in the vehicle width direction. In addition to the above, since the armrest is provided on the slide door, there is no situation where the armrest gets in the way when getting on and off using the side opening that is opened and closed by the slide door. .

A preferred mode based on the above solution is as described in claim 2 and the following claims. That is,
A storage recess for storing the armrest is formed on the inner side surface in the vehicle width direction of the slide door, and when the armrest is in the storage position, the inner side surface in the vehicle width direction of the slide door and the armrest are It is set so as to be substantially flush (corresponding to claim 2). In this case, the armrest in the storage position does not protrude inward in the vehicle width direction of the slide door, and the armrest in the storage position substantially constitutes the inner side surface of the slide door in the vehicle width direction. This is also preferable for improving the appearance from the vehicle interior side.

  The armrest is swingable about a swing axis extending in the front-rear direction set at a lower portion of the storage recess, and the position change between the use position and the storage position is performed according to the swing. It is set to be performed (corresponding to claim 3). In this case, the posture of the armrest can be changed between the use position and the storage position by a very simple movement of swinging. In addition, it is also preferable for minimizing the amount of displacement of the armrest in the vehicle width direction between the use position and the storage position.

The sliding door has an outer panel, an inner panel, and a trim material that covers the inner panel from the inner side in the vehicle width direction,
The storage recess is formed by recessing a part of the inner panel and the trim material outward in the vehicle width direction.
(Corresponding to claim 4). In this case, it is preferable to secure the appearance from the vehicle interior side with the trim material while making the wall portion defining the storage recess sufficiently strong.

  An urging means for urging the armrest toward the storage position is provided (corresponding to claim 5). In this case, it is preferable to prevent or suppress a situation where the armrest that is not used is automatically returned to the storage position and the driving toward the open position of the slide door is unnecessarily prohibited.

As an open command switch that is manually operated to issue an open command for the slide door, an inner handle switch provided on the inner handle of the slide door, an outer handle switch provided on the outer handle of the slide door, a driver's seat switch, the slide Having at least one of a door switch provided on the inner side surface of the door in the vehicle width direction and a portable keyless remote control switch;
The drive control means controls the drive means so that the slide door is driven toward the open position when an open command is issued by the open command switch, while the use state detection means When it is detected that the armrest is in the use position, it is set to perform control for prohibiting driving toward the open position of the slide door.
(Corresponding to claim 6). In this case, it is possible to prevent pinching while allowing the opening drive of the slide door to be easily started by operating the opening command switch.

  According to the present invention, when the slide door is displaced from the closed position to the open position, it is possible to prevent a foreign matter from being caught in the gap formed between the slide door and the rear edge of the side opening. it can.

  1 to 4, reference numeral 1 denotes a vehicle body, the B pillar (center pillar) of which is indicated by reference numeral 2, the C pillar located immediately after the B pillar 2 is indicated by reference numeral 3, and the C pillar 3 The last D-pillar located immediately after is indicated by reference numeral 4.

  As can be understood from FIG. 3 in particular, a side opening 10 is opened between the B pillar 2 and the C pillar 3 on the side surface of the vehicle body. This side opening 10 is used for passengers getting on and off using the rear seats (second row of seats) 11, the front edge portion thereof is constituted by the B pillar 2, and the rear edge portion C pillar 3. The lower edge portion is constituted by a side sill 12, and the upper edge portion is constituted by a roof side rail (the outer end portion in the vehicle width direction of the roof panel) 13.

  The side opening 10 is opened and closed by a slide door 20. That is, the slide door 20 can take a closed position (the state shown in FIG. 1) that covers (closes) the side opening 10 and an open position that opens the side opening 10. More specifically, the slide door 20 is displaced from the closed position in FIG. 1 to the outer side in the vehicle width direction and then moved rearward along the rear fender 14 so that the side opening 10 is almost completely opened. Open position (movement indicated by an arrow in FIG. 1). FIG. 2 shows a state in which the slide door 20 is once displaced outward from the closed position and slightly rearward. Of course, the return of the slide door 20 from the open position to the closed position is the reverse of the movement from the closed position to the open position. As will be described later, the slide door 20 is an electric type that is opened and closed by a motor.

  As shown in FIG. 3, the C pillar 3 constituting the rear edge portion of the side opening 10 includes a rear edge front surface portion 3 a and a rear edge side extending forward from the vehicle width direction inner side edge of the rear edge front surface portion 3 a. And a surface portion 3b. The outer end in the vehicle width direction of the rear edge front surface portion 3 a is continuous with the front end of the rear fender 13. In this way, the rear edge of the side opening 10 is a wet edge that is slightly recessed inward in the vehicle width direction from the rear fender 14 constituting the vehicle outer surface by the rear edge front surface portion 3a and the rear edge side surface portion 3b. Part 15 is configured. The wet edge corresponding to the wet edge 15 is also formed in each part of the B pillar 2, the side sill 12, and the roof side rail 13.

  The slide door 20 in the closed position is housed in the wet edge 15 so that the outer surface of the slide door 20 is flush with the rear fender 14. In other words, the degree of depression (dimension in the vehicle width direction) of the wet edge 15 (of the rear edge front surface portion 3a) inward in the vehicle width direction depends on the thickness of the slide door 20 in the vehicle width direction. Will be set. Moreover, the dimension in the front-rear direction of the rear edge side surface portion 3b is set to a dimension that allows draining (edge cutting) between the interior and exterior of the vehicle interior.

  On the inner side surface in the vehicle width direction of the slide door 20, an armrest 21, a storage box 22 for storing small items such as plastic bottles at a position in front of the armrest 21, and a pedestal portion 23 are formed to protrude. As shown in FIGS. 4 and 5, the armrest 21 has an upper surface height position slightly higher than the seat surface of the seat cushion 11 </ b> A of the rear seat 11 (substantially intermediate position in the vertical direction of the seat back 11 </ b> B). Is set to Further, the height position of the upper surface of the storage box 22 is set to a height position approximately the same as the seat surface of the seat cushion 11A. Further, the pedestal portion 23 is set so that the upper surface thereof is substantially the same height as the upper surface of the armrest 21, and an open / close switch 72 is attached to the upper surface of the pedestal portion 23, and upward from the upper surface of the pedestal portion 24. An inner door handle 24 is arranged. The opening / closing switch 72 commands opening / closing of the slide door 20 as will be described later. The inner door handle 24 gives a force for opening and closing the slide door 20. The inner door handle 24 is provided with an inner door switch for instructing opening and closing of the slide door 20, as will be described later. ing.

  The armrest 21 can selectively take a use position and a storage position. That is, in the use position shown by the solid line in FIGS. 1, 5, and 6, the slide door 20 is in the closed position with a predetermined amount (for example, about 5 to 10 cm) protruding from the inner side surface in the vehicle width direction of the slide door 20. In this state, the occupant sitting on the rear seat 11 can put his arm on the armrest 21. Further, the armrest 21 is retracted from the use position to the outer side in the vehicle width direction at the retracted position as shown by the one-dot chain line in FIGS. Is also made small enough. In the embodiment, the armrest 21 in the storage position is stored in a storage recess 80 formed on the inner side surface of the slide door 20 in the vehicle width direction, and is substantially flush with the inner side surface of the slide door 20 in the vehicle width direction. (Refer to the dot-dash line in FIG. 6, the amount of protrusion inward in the vehicle width direction is set to be substantially zero).

  Details of the vicinity of the armrest 21 will be described together with the storage recess 80. First, as shown in FIG. 6, the slide door 20 is composed of an outer panel 20A, an inner panel 20B, and a trim material 20C that covers the inner panel 20B from the inner side in the vehicle width direction. The inner panel 20B and the trim material 20C are formed with the above-described storage recesses 80 in a portion slightly lower than the belt line by being partially recessed outward in the vehicle width direction.

  The armrest 21 is held by the slide door 20 so as to be swingable about a support shaft 81 extending in the front-rear direction. The support shaft 81 is positioned below the storage recess 80 and is rotatably held by a pair of front and rear holding brackets 82 fixed to the bottom surface of the storage recess 80 (the rear holding bracket is not shown). . As a result, the armrest 21 is swung around the support shaft 81 and takes a use position extending substantially horizontally and a storage position swung outward from the use position by about 90 degrees in the vehicle width direction. To get. Even when the armrest 21 in the use position is supported from below at the end in the vehicle width direction by the bottom wall portion of the storage recess 80 and the occupant's arm is placed on the armrest 21 in the use position. The armrest 21 is firmly maintained in a substantially horizontal use position without being swung downward. Note that the armrest 21 has a lower surface at the use position in the vehicle width direction in the vehicle width direction at the storage position, and thus a portion that becomes the lower surface at the use position is finished with a good appearance (for example, the same material as the trim material 20C). Finish to have a physical experience).

  As shown in FIG. 7, the armrest 21 is urged toward the storage position by a return spring 83. In addition, the armrest 21 includes a click mechanism 85 between the holding bracket 82 and secures a sense of moderation at the use position and the storage position, and holds the use position or the storage position unless a large external force is applied. Has been. That is, the click mechanism 85 includes a locking hole 86 formed in the holding bracket 82, a locking member 87 held by the armrest 21, and a spring 88 that biases the locking member 87 toward the locking hole 86. Have. When the locking member 87 is fitted and locked in the locking hole 86, the armrest 21 holds its position against the urging force of the return spring 83. Two such locking holes 86 are provided corresponding to the use position and the storage position.

  When the armrest 21 is in the use position, the locking member 87 is fitted and locked in the one locking hole 86, and the use position is held against the urging force of the return spring 83. Similarly, when the armrest 21 is in the storage position, the locking member 87 is fitted and locked in the other locking hole 86 and is securely held in the storage position together with the urging action of the return spring 83. Will be. When the armrest 21 in the storage position is swung toward the use position, the engagement member 87 is disengaged from the engagement hole 86 corresponding to the storage position, and a sense of moderation is given. When the locking member 87 is fitted, the locking member 87 is fitted and locked in the locking hole 86 corresponding to the use position, thereby giving a sense of moderation. When the user (occupant) feels such a moderation feeling, it is possible to know whether the armrest is reliably in the use position or the storage position. This is the same when the armrest 21 is swung from the use position to the storage position.

  In FIG. 8, it is detected by the pressure-sensitive switch 90 as a use state detection sensor that the armrest 21 is in the storage position (in other words, in the use position). The pressure-sensitive switch 90 includes a casing 91, a detection member 92 that is slidably held in the casing 91 in the vehicle width direction, and a spring 93 that urges the detection member 92 inward in the vehicle width direction. The switch member 94 (for example, a member whose electrical characteristics are changed by receiving a pressing force) that is turned on when the detection member 92 is displaced outward in the vehicle width direction by a predetermined amount or more. The casing 91 is fixed to the inner panel 20 </ b> B of the slide door 20, and the detection member 92 is disposed so as to protrude into the storage recess 80. As a result, when the armrest 21 is in the storage position, the detection member 92 is pressed and displaced outward in the vehicle width direction by the armrest 21, and the pressure sensitive switch 90 is turned on (the armrest 21 is in the storage position). And when the pressure sensitive switch 90 is OFF, it is detected that the armrest 21 is in the use position).

  Due to the displacement of the slide door 20 from the closed position toward the open position, there is a gap between the inner side surface in the vehicle width direction of the slide door 20 and the C pillar 3 (the outer end in the vehicle width direction). S is formed (see FIGS. 2 and 4). For example, when the slide door 20 is displaced from the closed position toward the open position while the occupant is placing his arm on the armrest 21, for example, an arm as an object (foreign matter) enters the gap S and is sandwiched. There is a possibility. However, as will be described later, when the armrest 21 is in the use position, that is, when there is a high possibility that an occupant's arm or the like is placed on the armrest 21, the slide door 20 in the closed position is directed to the open position. Driving is prohibited, and pinching is prevented. Of course, the detection that the armrest 21 is in the use position is performed by the pressure-sensitive switch 90.

  FIG. 9 shows an example of a drive portion of the slide door 20 that is electrically driven. In FIG. 7, reference numeral 60 denotes a guide rail, and the guide rail 60 is fixed to the vehicle body so as to extend along the rear fender 14 from the wet edge 15. A slider 62 such as a pulley held by a bracket 61 slidably held at the rear end of the slide door 20 is fitted into the guide rail 60 so that it can move smoothly.

  A guide wire 63 is connected to the bracket 61. The guide wire 63 is disposed along the guide rail 60 by a guide pulley 64. The guide wire 63 is reciprocated by the drive mechanism 65. That is, the drive mechanism 65 has a drive pulley (not shown) engaged with the motor 65a, the speed reduction mechanism 65b, and the guide wire 64. The guide wire 63 is driven to reciprocate by driving the drive pulley forward or backward through the speed reduction mechanism 65b by the motor 65a. Of course, the slide door 20 is driven between the closed position and the open position by the reciprocating movement of the guide wire 63.

  FIG. 10 shows a control system of the motor 65a, and U in the figure is a controller (control unit) configured using a microcomputer. In addition to the signals from the pressure-sensitive switch 90, signals from various switches 71 to 75 are input to the controller U. Each of the switches 71 to 75 is manually operated to command opening / closing of the slide door 20. That is, the switch 71 is provided in the driver's seat, the slide door switch 72 is provided on the upper surface of the pedestal portion 23 as described above, and the remote control switch 73 is carried by the passenger. The inner door switch 74 is activated in response to the opening / closing operation of the inner door handle 24 described above. Similarly, the outer door switch 75 is provided on an outer side surface of the slide door 20 in the vehicle width direction, and is provided on an outer door handle (not shown) to which an external force in the opening / closing direction is given by an occupant trying to sit on the rear seat 11. It was attached. Note that the opening / closing switch may have only a part of the above five types.

  When the controller U receives an open command from any one of the switches 71 to 75 in a state where the slide door 20 is in the closed position, the controller U drives the motor 65a toward the open position. Execute the control in the direction to do. When the slide door 20 is in the closed position and the pressure sensitive switch 90 detects that the armrest 21 is in the use position, even if the opening command is issued, the slide door 20 is moved toward the open position. Driving is prohibited.

  The control content of the controller U described above is shown in the flowchart of FIG. Hereinafter, this flowchart will be described. In the following description, Q indicates a step. In addition, the flowchart of FIG. 9 is started on the premise that the vehicle speed is 0 (stopped) from the viewpoint of safety. First, at Q1, it is determined whether or not the slide door 20 is currently in the closed position. If the determination in Q1 is YES, it is determined in Q2 whether or not there is an open command signal from at least one of the switches 71 to 75. If the determination in Q2 is YES, it is determined in Q3 whether or not the armrest 21 is in the use position based on the signal from the pressure sensitive switch 90. If the determination in Q3 is NO, the slide door 20 is driven toward the open position in Q4 (drive control of the motor 65a). If YES in Q3, the drive toward the open position of the slide door 20 is prohibited (drive prohibition of the motor 65a). If NO in the determination of Q1 or NO in the determination of Q2, the process returns without passing through Q4 or Q5, respectively.

  Although the embodiments have been described above, the present invention is not limited to the embodiments, and appropriate modifications can be made within the scope of the claims. When it is detected that the armrest 21 is in the use position while the slide door 20 is being driven toward the open position (the drive control is being executed in Q4), the drive toward the open position is stopped. In this case, after the driving is stopped, the slide door 20 can be controlled to be slightly reversed toward the closed position. The posture of the armrest 21 may be changed between the use position and the storage position by displacing the armrest 21 in the vehicle width direction while maintaining the substantially horizontal state as a whole instead of swinging. For example, the armrest 21 may be locked at the storage position without urging the armrest 21 toward the storage position (to enter the use position, after the lock is released). Whether the armrest 21 is in the use position or the storage position can be detected using an appropriate switch or sensor. When the sliding door 20 in the closed position is set to the open position, the amount of displacement that is displaced toward the outer side in the vehicle width direction is set to the side opening 10 when the armrest 21 is in the use position. It may be set to be sufficiently large so that it does not contact the rear body panel, but the amount of displacement outward in the vehicle width direction is set small on the assumption that the armrest 21 is in the storage position. May be. In order to easily change the armrest 21 in the storage position to the use position, the operation unit 21a such as a handle held by the occupant is placed on the lower surface of the armrest 21 in the use position (the vehicle width direction of the armrest 21 in the storage position). It can also be provided on the inner side. Of course, the object of the present invention is not limited to what is explicitly stated, but also implicitly includes providing what is substantially preferred or expressed as an advantage.
