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.

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 foreign object is detected in the gap by a pressure sensor provided on a slide door. Japanese Patent Application Laid-Open No. H10-228561 also discloses that when the foreign object is caught, the driving of the sliding door is stopped or the sliding door is driven in a direction in which the sandwiching 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).

JP 2007-56522 A Japanese Patent Laid-Open No. 11-182136

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.

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 covering the side opening formed on the side surface of the vehicle body, and the side opening by being moved rearward along the outer side surface of the rear vehicle body once displaced outward from the closed position in the vehicle width direction. An open position, and a sliding door adapted to take
The rear edge portion of the side opening has a rear edge front surface portion extending in the vertical direction and facing forward, and a rear edge side surface portion extending forward from the vehicle width direction inner side end of the rear edge front surface portion. The rear edge front surface portion and the rear edge side surface portion constitute a wet edge portion that is concave toward the vehicle body inward side,
When the slide door is displaced from the closed position toward the open position, the wet edge extends in the vehicle width direction and extends in the vehicle width direction of the slide door and the rear edge of the side opening. A shielding member which is an operating position that shields a gap formed between
The shielding member is operated so as to shield the gap in conjunction with the displacement of the sliding door from the closed position toward the open position;
When the sliding door is in the closed position, the shielding member is a storage position in which the shielding member is stored in a space between the sliding door and the wet edge.
It is like that. According to the above solution, when the slide door is displaced from the closed position toward the open position, the shielding member is set to the operating position extending in the vehicle width direction, and the slide door and the rear edge of the side opening are Since the gap formed between them is shielded, a situation in which an object on the vehicle interior side is caught in the gap as a foreign object is surely prevented. In addition, since the shielding member is disposed by effectively using the concave wet space, it is not necessary to secure a special space for the shielding member. In addition to the above, the shielding member is moved to the operating position in conjunction with the displacement from the closed position to the open position of the sliding door, that is, in conjunction with the formation of the gap. It can be reliably shielded by the shielding member.

A preferred mode based on the above solution is as described in claim 2 and the following claims. That is,

The shielding member is a plate extending in the vertical direction,
The shielding member is held by the vehicle body so that the inner end in the vehicle width direction when it is in the operating position can swing about a swing axis extending in the vertical direction. It is to be taken the storage position extending in the longitudinal direction along the trailing edge surface and the said working position,
A biasing means for biasing the shielding member toward the operating position is provided,
When the sliding door is displaced from the closed position toward the open position, the shielding member is swung toward the operating position by the biasing means, while the slide door is closed from the open position to the closed position. When it is displaced toward the position, it is pressed by the sliding door to be the storage position.
(Corresponding to claim 2 ). In this case, it is preferable to make the shielding member into a plate shape and to make the shielding member itself have a simple structure and not to occupy a large volume as much as possible. Further, the shielding member can be automatically switched between the storage position and the operation position in conjunction with opening and closing of the slide door by a simple structure using the swinging and urging means.

The shielding member is configured such that the shape of the outer end side in the vehicle width direction when set to the operating position is set to a shape along the shape of the inner side surface in the vehicle width direction of the slide door. Item 3 ). In this case, it is preferable to shield the gap over the longest possible range in the vehicle width direction while preventing interference between the sliding door displaced toward the open position and the shielding member at the operating position.

On the inner side surface in the vehicle width direction of the slide door, an armrest is formed to protrude,
A cutout portion having a shape corresponding to the armrest is formed on the outer end side in the vehicle width direction when the operating position is set in the shielding member.
(Corresponding to claim 4 ). In this case, it is possible to prevent interference between the armrest and the shielding member while allowing the passenger to use the armrest of the slide door in the closed position. In addition, when the sliding door is displaced toward the open position, it is necessary to displace the sliding door larger outwardly in the vehicle width direction by the amount of the armrest. However, a large gap in the vehicle width direction can be shielded by the shielding member, and pinching can be reliably prevented.

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.

The C pillar 3 constituting the rear edge portion of the side opening 10 includes a rear edge front surface portion 3a and a rear edge side surface portion 3b extending forward from the inner end in the vehicle width direction of the rear edge front surface portion 3a. 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 body 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 and a storage box 22 for storing small items such as plastic bottles at a position in front of the armrest 21 are formed to protrude. As shown in FIG. 4, the armrest 21 is set so that the upper surface height position is 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). Has been. Moreover, although the upper surface height position of the storage box 22 is set to a height position approximately the same as the seat surface of the seat cushion 11A, the height position is not particularly limited.

A shielding member 30 is disposed on the wet edge 15. The shielding member 30 is configured to have rigidity as a whole by, for example, a synthetic resin or a light metal, and is plate-like and extends in the vertical direction in the embodiment. The shielding member 30 can take an operation position extending in the vehicle width direction shown by a solid line in FIGS. 2 and 3 and a storage position shown by a one-dot chain line in FIGS. The shielding member 30 extends in the vehicle width direction at the operating position and is in a state along the rear edge front surface portion 3a. Further, the side wall portion 30 extends in the front-rear direction and is in a state along the rear edge side surface portion 3b at the storage position.

The shielding member 30 is attached to the vehicle body (C pillar 3) so as to be able to swing about a swing axis extending in the up-down direction around the inner end in the vehicle width direction when the shielding member 30 is in the operating position. . Such a shielding member 30 is urged toward the operating position, as will be described later. As a result, the slide door 20 is automatically swung toward the operating position in conjunction with the displacement of the slide door 20 from the closed position to the open position. When the slide door 20 is displaced from the open position to the closed position, the shielding member 30 is pressed by the slide door 20 and automatically returned to the storage position. As will be described later, when the shielding member 30 is in the operating position extending in the vehicle width direction, further swinging is restricted.

FIG. 5 shows a state in which the shielding member 30 is in the storage position. In FIG. 5, the alternate long and short dash line schematically shows a cross-sectional structure near the C pillar 3 at the upper surface height position of the armrest 21. is there. FIG. 6 shows a state in which the shielding member 30 is in the operating position, and the alternate long and short dash line schematically shows a cross-sectional structure in the vicinity of the C pillar 3 at the upper surface height position of the armrest 21.

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, 4 and 6). In conjunction with the formation of the gap S (the slide door 20 is displaced from the closed position toward the open position), the shielding member 30 automatically becomes the operating position, and the gap S is moved from the front. It will be shielded. The shielding range of the gap S by the shielding member 30 is set to a height range related to the occupant seated on the rear seat 11. That is, the shielding member 30 covers the gap S in a range from the seat surface height position of the seat cushion 11A to a position slightly pulled from the upper end of the seat back 11B in the standing position.

When the shielding member 30 is not present, a foreign matter in the vehicle interior enters the gap S, and the space between the inner side surface in the vehicle width direction of the slide door 20 and the outer end surface in the vehicle width direction (as a result, the rear fender 14) of the C pillar 3. However, the provision of the shielding member 30 will surely prevent such foreign matter from being caught.

In particular, as apparent from FIG. 4, the shape of the shielding member 30 at the operation position on the outer end side in the vehicle width direction corresponds to the shape of the inner side surface in the vehicle width direction of the slide door 20 (uneven shape such as the armrest 21). The shape is made. Specifically, a cutout portion 30 a having a shape corresponding to the armrest 21 is formed on the outer end of the shielding member 30 in the vehicle width direction. Thereby, when the slide door 20 is displaced from the closed position toward the open position, the slide door 20 and the shielding member 30 are prevented from interfering with each other, and the gap S is as wide as possible in the vehicle width direction (long). ) Covered by the shielding member 30 over a range.

7 to 9 show specific examples of assembly of the shielding member 30 to the vehicle body. First, a support shaft 35 extending in the vertical direction is rotatably held at a position corresponding to the inner end of the shielding member 30 in the vehicle width direction at the operating position. The upper and lower ends of the support shaft 35 are rotatably supported by the holding bracket 40. Since the upper and lower holding brackets 40 have the same configuration, the assembling relationship with the shielding member 30 will be described focusing on the upper holding bracket 40.

First, the holding bracket 40 is fixed to the vehicle body (wetting edge 15) by a fixture 41 such as a bolt. The support shaft 35 is inserted into a holding hole 41 formed in the holding bracket 40, and the screw 44 restricts the removal of the support shaft 35 from the holding hole 41. A concave portion 40a is formed on the lower surface of the holding bracket 40, and a spiral spring 43 as an urging means is accommodated in the concave portion 40a. The spiral spring 43 is disposed so as to surround the support shaft 35. One end of the spiral spring 43 is locked to the holding bracket 40, and the other end is locked to the shielding member 30. The shielding member 30 is urged toward the operating position by such a spiral spring 43. The holding bracket 40 is formed with a stopper portion 40b projecting downward so that the situation in which the shielding member 30 is further swung beyond a predetermined operating position is restricted. The stopper portion 40b is also formed on the lower holding bracket 40 so that the upper and lower stopper portions 40b reliably regulate the situation where the shielding member 30 is further swung beyond a predetermined movement position. It has become.

In order to prevent the situation where the shielding member 30 is further swung beyond the predetermined operating position, the rear edge front surface portion 3a is set immediately after the shielding member 30 at the predetermined operating position. You can also Further, in the case where the sliding door 20 is particularly electrically operated, when a large external force greater than a predetermined value from the front side to the rear side is applied to the shielding member 30 in the operating position, the sliding door 20 is driven in the opening direction. The sliding door 20 may be stopped, or may be slightly reversely driven toward the closed position.

In order to detect that a large external force more than a predetermined amount is applied to the shielding member 30 in the operating position, for example, a pressure sensitive switch 50 as shown in FIG. 7 may be separately provided. That is, as the pressure sensitive switch 50, for example, a casing 51 fixed to the rear edge front surface portion 3a, a contact 52 that can be displaced in the front-rear direction in the casing 51, and a contact disposed in the casing 51 are provided. And a spring 53 that biases 52 forward, and a switch (not shown) that is disposed in the casing 51 and is turned on when the contact 52 is displaced more than a predetermined distance backward. . And it is set as the arrangement | positioning aspect which the contactor 52 was located in the immediate back of the shielding member 30 in an operating position. The biasing force of the spring 53 is set to be sufficiently larger than the biasing force of the spiral spring 43. As a result, when a large external force greater than a predetermined value from the vehicle interior side acts on the shielding member 30 in the operating position, the pressure-sensitive switch 50 is turned on and a large external force acts on the shielding member 30 backward. Is detected.

Although the embodiment has been described above, the present invention is not limited to the embodiment, and can be appropriately changed within the scope described in the scope of claims. For example, the invention includes the following cases. . The shielding member 30 may have, for example, a vertically divided structure. By adopting the divided structure, the gap S can be widened in the vehicle width direction as much as possible to easily cope with the shape change in the vertical direction of the rear edge front surface portion 3a. This is preferable for shielding over a range. 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.
