Description

  The present invention relates to a sealing structure for a vehicle opening / closing body that closes a gap between the peripheral portions of the opening / closing body and the opening when the opening of the vehicle body is closed by the opening / closing body.

In a vehicle, as a sealing structure of an opening / closing body, a door opening (opening) is provided in a vehicle body, a side door for opening / closing the door opening is provided, and a flexible pressing member is provided at a peripheral portion of the opening / closing body. There is a configuration in which air is supplied to the hollow portion of the pressing member to expand the pressing member so as to press the pressing member against the peripheral portion of the opening (see, for example, Patent Document 1).
JP-A-6-255366

  According to this sealing structure of the opening / closing body, the peripheral portion of the opening / closing body and the peripheral portion of the door opening are provided by supplying air to the hollow portion of the pressing member to expand the pressing member and pressing the peripheral portion of the opening The rigidity of the vehicle body can be increased.

Here, the seal structure of patent document 1 is a structure which presses a flexible press member to the peripheral part of an opening part.
For this reason, for example, when the wind pressure between the peripheral edge of the opening and closing body and the peripheral edge of the opening is relatively high, the flexible pressing member is deformed to sufficiently secure the sealing performance between the peripheral edges. Difficult to do.
Furthermore, it is difficult to sufficiently increase the rigidity of the vehicle body simply by pressing the flexible pressing member against the peripheral edge of the opening.

  The present invention provides a sealing structure for a vehicle opening / closing body that can sufficiently enhance the sealing performance between the peripheral edge of the opening / closing body and the peripheral edge of the opening, and can sufficiently increase the rigidity of the vehicle body. This is the issue.

  The invention according to claim 1 is provided with an openable / closable body that is openable and closable with respect to the opening of the vehicle body, and in a state in which the open / closed body is closed, between the peripheral edge of the openable / closable body and the peripheral edge of the opening. A seal member for a vehicle opening / closing body that is provided at one peripheral portion of the vehicle body and the opening / closing body, and that can project toward the other peripheral portion of the vehicle body / opening / closing body; And a fitting groove formed on the peripheral edge and capable of receiving the protruding seal member.

In the invention according to claim 1, the seal member is provided on one peripheral portion of the vehicle body and the opening / closing body so as to protrude toward the other peripheral portion. Furthermore, a fitting groove is provided on the other peripheral edge, and the sealing member is received in this fitting groove.
Therefore, by inserting the seal member into the fitting groove, the gap between the peripheral portion of the opening / closing body and the peripheral portion of the opening can be reliably closed with the seal member.
Thereby, there exists an advantage that the sealing performance between the peripheral part of an opening-and-closing body and the peripheral part of an opening part can fully be improved.

Furthermore, the opening / closing body can be suitably connected to the vehicle body by inserting the seal member into the fitting groove.
Thereby, there is an advantage that the integrity of the vehicle body and the opening / closing body is enhanced, and the rigidity of the vehicle body can be sufficiently increased.

Specifically, the rear seal member 20 is stored in the rear storage portion 31, and the lower seal member 21 is stored in the lower storage portion 32.

ST17: It is determined whether or not the door is locked. If not locked, the process returns to ST17, and if locked, the process proceeds to ST18.
ST18: It is determined whether or not the engine is operating. If it is driven, the process returns to ST12, and if it is not driven, the control is terminated.

The projecting and retracting means 25 shown in the above embodiment is merely an example, and the present invention is not limited to this.
The rear seal member 20 and the lower seal member 21 may be provided with a function of projecting and retracting to the storage position and the protruding position.

  Moreover, in the said embodiment, although the back seal member 20 and the lower seal member 21 were demonstrated as a substantially rectangular blade, it is not restricted to this, It is possible to form in arbitrary shapes.

  Furthermore, in the said embodiment, although the side door 14 was illustrated as an opening / closing body, it is not limited to this, You may make it apply to other doors, such as a rear door.

  Moreover, although the said embodiment demonstrated the example which protrudes a sealing member from the rear part or the lower part among the door peripheral parts 15, it is not restricted to this, A sealing member from the front part or the upper part among the door peripheral parts 15 is demonstrated. It is also possible to make it project.

Further, in addition to the flowchart shown in FIG. 14 of the above embodiment, for example, the seal member 20 is interlocked with a mechanism that locks the door when the vehicle reaches a predetermined speed and releases the door lock when the vehicle enters the parking range. , 21 can be configured to project and retract.
Further, for example, when an airbag deployment signal is output, it is desirable that the seal members 20 and 21 be housed in the door.

  INDUSTRIAL APPLICABILITY The present invention is suitable for application to a vehicle having a sealing structure for a vehicle opening / closing body that closes a gap between the opening / closing body and the peripheral edge of the opening when the opening of the vehicle body is closed by the opening / closing body. .
