Description

  The present invention is attached to a sliding door or a vehicle body of an automobile, and when the sliding door is closed, a part of a human body such as a finger or a foot or an object is sandwiched between the door and the vehicle body or between the doors. Further, the present invention relates to a weather strip made of rubber or resin provided with a sensor for detecting this.

  In a car, there is a slide door that is opened and closed by a power slide door device at one of the places where a sensor for detecting the pinching of a human body or an object is attached. The slide door 1 shown in FIG. 1 is an example, and a weather strip made of rubber or resin having a sensor for detecting pinching is attached to the front edge of the slide door. 2 shows a cross section of the weather strip 2 along the line AA in FIG. 1, FIG. 3 shows a cross section of the weather strip 2 along the line BB, and the weather strip 2 shown in FIG. 2 is shown in FIG. A mounting portion 5 having a substantially U-shaped cross-section in which the metal core 4 is embedded, and a sensor housing portion 6 formed to protrude from the top of the mounting portion 5; Of the both side walls constituting the mounting part 5, the other side wall among the side walls which project from the extension of one side wall and house the lead wire connected to the sensor, and the other side wall constituting the mounting part 5. The seal portion 11 is formed so as to protrude from the side surface and seals between the slide door 1 and the front door 8 when the slide door 1 is closed and hits the flange 9 of the front door 8. , Part of the human body or objects A sensor (not shown) for detecting an electrical change such as the current value of the current flowing through the electric circuit and the resistance value of the circuit when the lead wire is received, and the lead wire storage portion 7 has a lead wire (not shown) connected to the sensor. Each is inserted.

  The weather strip 2 shown in FIG. 3 has the same structure as the weather strip 2 shown in FIG. The seal part is inherently effective for sound performance and water tightness, but on the other hand, there is concern about the door closing performance and damage to the car body panel paint. Especially, the sliding door is partly because the vibration is larger than other door structures. Has been cut. In addition, some weather strips have products in which a seal portion partially exists or does not exist in one weather strip. Some products have a seal portion over the entire length, and some products do not have a seal portion set in advance in order to reduce the price. is there. These products are selected according to the vehicle type of the vehicle to be installed.

As for the weather strip, in addition to this, an attachment portion attached to the flange of the body and a hollow seal portion of the weather strip made up of the hollow seal portion can be removed (Patent Document 1). Among door weather strips and sub seals that elastically contact the body when closed, there is known a device that can be attached by fitting the sub seal to the door weather strip (Patent Document 2).

  The weather strip shown in FIGS. 2 and 3 can be manufactured by changing the die, changing the die or cutting the seal portion each time, whether it is extruded or connected by molding. Manufacturing a weather strip with a different cross-section depending on the vehicle type and mounting location each time results in deterioration of production efficiency.

  It is an object of the present invention to easily provide a weather strip having a necessary cross section according to a vehicle type and an installation location without causing deterioration in production efficiency.

  The invention according to claim 1 is attached to a sliding door or a vehicle body of an automobile, and when the sliding door is closed, a part or an object of a human body such as a finger or a foot is between the sliding door and the vehicle body or between the sliding door and the front. A weather strip made of rubber or resin having a sensor for detecting this when sandwiched between the door and a mounting portion having a storage portion into which the sensor is inserted, and a hardness from the mounting portion It is made of a large material, and has a first core member that is inserted by exposing a part of the mounting part and having a fitting part formed in the exposed part, and the sliding door is closed to the mounting part. A seal portion that seals between the slide door and the vehicle body or between the slide door and the front door can be attached, and the seal portion is formed of a material having a higher hardness than the seal portion; and Above fitting The second core material formed by exposing the fitting part that can be fitted to the part from the seal part is inserted, and the fitting part is forcibly fitted to the fitted part, whereby the sealing part becomes the attachment part. It can be attached.

  The invention according to claim 2 is the invention according to claim 1, wherein the attachment portion and the first core member have a substantially U-shaped cross section, and are on the extension of one of the side walls constituting the attachment portion. A housing portion for receiving the sensor lead wire is formed in the first portion, and the fitted portion is formed at an end portion of the first core member.

  According to the present invention, a weather strip without a seal portion or a weather strip with a seal portion attached is provided according to the vehicle type and attachment location, and the seal portion is attached by forcing the fitting portion to the fitting portion on the attachment portion side. This can be done simply by combining them. In addition, the weather strip that does not have a seal part and the seal part are molded separately. However, molding the seal part is simpler and easier to manufacture than the entire weather strip with a seal part is molded. It is easy and production efficiency can be improved.

  A weather strip according to an embodiment of the present invention will be described below with reference to the drawings. In the figure, the same reference numerals are given to the same structural portions as those of the weather strip shown in FIGS.

  The weather strip 21 shown in FIG. 5 has a substantially U-shaped cross-section attachment portion 5 made of rubber such as EPDM or a thermoplastic elastomer, and is inserted into the attachment portion 5. A first core member 22 made of a resin such as polypropylene, polyethylene, polyamide, and the like, an annular sensor housing portion 6 that protrudes from the top of the mounting portion 5 and passes the sensor, and the mounting portion 5 Of the side walls of the mounting portion 5, which protrudes from the extension of one side wall and includes a hook-like lead wire storage portion 7 in which a sensor lead wire (not shown) is accommodated. The end portion of the first core member 22 is exposed, and a fitting recess 23 which is a fitted portion is formed at the exposed end portion.

  The seal portion 24 is also made of rubber such as EPDM or thermoplastic elastomer, and a material having a high hardness, for example, a second core material 25 made of polypropylene is inserted into the seal portion 24 in the same manner as the first core material 22. A projecting portion 26, which is a fitting portion that can be forcibly fitted to the fitting recess 23, protrudes from one end of the core member 25 exposed from the seal portion 24.

  In use, the weather strip 21 shown in FIG. 6 is used alone or the convex portion 26 of the seal portion 24 is forcibly fitted to the fitting concave portion 23 of the mounting portion 5 depending on the vehicle type and the mounting location. As shown in FIG. 7, the seal portion 24 is used in a connected state.

  The first and second core members 22 and 25 of the embodiment described above use, for example, polypropylene as a material having high hardness, but other materials such as metal such as steel may be used.

  The weather strip of this embodiment is attached to the front edge of the slide door and seals the front door. However, the weather strip can be applied to a weather strip that seals between the front door and the vehicle body. It can also be applied to weatherstrips that attach and seal between sliding doors.
