Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door sealing material which is mounted on an opening of a vehicle body of an automobile to seal a gap between the door window glass and the door.

[0002]

2. Description of the Related Art Door seal materials of this type include a glass run mounted on a sash of a side door and a weather strip mounted on a side door opening of a vehicle body. In a motor vehicle equipped with a power window device, if foreign matter is caught when the door window glass rises, it is necessary to immediately stop and lower the rise of the door window glass. For this reason, it is common to install a pressure-sensitive sensor in these door seal materials. As for the installation of the pressure-sensitive sensor, for example, as disclosed in Japanese Patent Application Laid-Open No. Sho 60-105785, a method of integrally forming the pressure-sensitive sensor with a door seal material and a method of bonding and fixing the same have been proposed.

[0003]

However, according to the former method, it is difficult to install a pressure-sensitive sensor in a molded part, and an insensitive part is easily generated in a corner or a terminal.

[0004] On the other hand, according to the latter method, the pressure-sensitive sensor must be accurately attached to the door seal material along the longitudinal direction, which requires not only a great deal of work but also a difference in color and texture between the two. It is easy to occur and there is a problem in appearance. Further, since the pressure-sensitive sensor is exposed, abrasion and scratches are easily generated, and there is a problem in durability.

[0005] In view of such circumstances, an object of the present invention is to provide a door seal material for an automobile which can prevent generation of a non-sensible portion, can improve workability and appearance, and has good durability.

[0006]

According to the present invention, there is provided a door seal material which is mounted on an opening of a vehicle body and seals a gap between the door window glass and the door seal material. A pressure-sensitive sensor having a lead-wire holding portion bulging from the surface of the main body is provided while forming the pressure-sensitive sensor storage portion, and the pressure-sensitive sensor is sensed while engaging the lead wire holding portion with the locking groove. It is characterized in that it is inserted into the pressure sensor storage section.

[0007] The lead wire holding portion may be constituted by a pair of locking pieces to which the lead wire can be fitted.

The lead wire holding portion may be formed by integrally forming a lead wire with the pressure-sensitive sensor main body.

[0009]

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

FIG. 7 shows a glass run of the present invention.
In the glass run 1, a pressure-sensitive sensor 3 is installed in a portion 1 a attached to a front side 2 a of a sash 2. FIG. 2 shows a part of this portion 1a cut in the longitudinal direction. The upper portion of the sash front side mounting portion 1a is formed by molding, and the lower portion is formed by extrusion. The sash front side mounting portion 1a has a pressure-sensitive sensor housing 4
Are formed along the longitudinal direction, and the pressure-sensitive sensor housing portion 4 is formed so that the upper end thereof straddles the molded portion.

The glass run 1 includes a channel portion 6 in which a side edge of the door window glass 5 is accommodated, and inner and outer lip portions 7 and 8 which are in close contact with the door window glass 5.
The pressure-sensitive sensor storage unit 4 includes a main unit 9 facing the channel unit 6.
(See FIG. 3). A locking groove 10 is formed on the bottom wall 4a of the pressure-sensitive sensor housing 4 over substantially the entire length.

As shown in FIG. 1, lead wires 11 and 12 are connected to both ends of the pressure-sensitive sensor 3, respectively. One of the lead wires 11 is fitted in locking pieces 13, 13 as a lead wire holding portion and arranged in the longitudinal direction, and the tip is connected to the connector 14 together with the other lead wire 12. I have. The pressure-sensitive sensor 3 is inserted into the pressure-sensitive sensor housing 4 from the lower end opening 4 a while engaging the locking piece 13 with the locking groove 10 of the pressure-sensitive sensor housing 4.

By the way, the lead wires 11 of the pressure-sensitive sensor 3,
Reference numeral 12 is connected to a controller 15 so that when the pressure-sensitive sensor 3 detects the foreign material being caught when the door window glass 7 is raised, the door window glass 7 immediately stops and descends. FIG. 4 shows a connection circuit between the pressure-sensitive sensor 3 and the controller 15. The reason why signals are extracted from both ends of the pressure-sensitive sensor 3 through the leads 11 and 12 in this manner is that even if the electrode 3a in the pressure-sensitive sensor 3 breaks in the middle, the portion from there to the undetected portion This is to prevent the occurrence of A coaxial cable is used for the lead wire 11 extending from the upper end of the pressure-sensitive sensor 3, and the core wire 11 a and the ground wire 11 b are connected to
a, 3a.

Since the present embodiment is configured as described above,
The pressure-sensitive sensor 3 can be easily installed in the molded portion at the upper end corner, and no insensitive portion is generated.

Further, the time and effort for bonding and fixing the pressure-sensitive sensor 3 to the glass run 1 can be omitted, and not only the workability is improved, but also
Since the pressure-sensitive sensor 3 is not exposed on the surface of the glass run 1, the appearance and durability are improved.

Furthermore, since the lead wire 11 can be inserted into the pressure-sensitive sensor housing 4 with the lead wire 11 being routed to the pressure-sensitive sensor 3, there is no trouble in the operation.

Furthermore, since the locking piece 13 of the pressure-sensitive sensor 3 is engaged with the locking groove 10 of the pressure-sensitive sensor housing 4, there is no risk of the pressure-sensitive sensor 3 being twisted during use.

In this embodiment, a coaxial cable is used for the lead wire 11, but when a normal lead wire is used, the locking piece 13 is attached to the pressure-sensitive sensor 3 as shown in FIG.
May be provided as a pair.

Alternatively, as shown in FIG. 6, a pair of protrusions 20 as lead wire holding portions may be formed on the pressure-sensitive sensor 3, and lead wires 21 may be molded there. In this case, the connection member 30 may be fitted between the electrodes 3a of the pressure-sensitive sensor 3 to achieve electrical connection with the lead wires 21. The connection member 30 has conductors 23 adhered to both sides of the insulator 22, and when fitted into the pressure-sensitive sensor 3, tongue pieces 24, 24 extending from the conductors 23, 23.
Are brought into contact with the tips of the lead wires 21, 21, respectively.

[0020]

According to the present invention, a pressure-sensitive sensor can be easily installed even in a molded portion, and no insensitive portion is generated. Further, the time and effort for bonding and fixing the pressure-sensitive sensor are omitted, and not only the workability is improved, but also the appearance and durability are improved because the pressure-sensitive sensor is not exposed on the surface.

Further, since the lead wire can be inserted into the pressure-sensitive sensor storage portion in a state where the lead wire is routed to the pressure-sensitive sensor by the lead wire holding portion, there is no trouble in the operation.

Further, since the lead wire holding portion of the pressure-sensitive sensor is engaged with the locking groove of the pressure-sensitive sensor housing portion, there is no fear that the pressure-sensitive sensor is twisted during use.
