Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in door weather strips for automobiles.

As shown in Figure 4, door weather strips have traditionally been used as door weather strips that are attached to the door side of a car to seal between the door and the car body and prevent rainwater, car wash water, etc. from entering the car interior. A door frame 1 of a door sash portion fixedly attached to the upper part has a frame outer part 10 extending in a vertical direction, which is the door height direction, and a frame outer part 10 extending in a substantially horizontal direction toward the inside of the door at approximately the center of this frame outer part 10. and a weather strip base 31 held by the retainer 2.
A door weather strip 30, which is formed by integrally molding a hollow main lip 32 and a sub-rip 33, is used in each of the inner door part 311 and the outer part 312 of the door.

This door weather strip 30 has a main lip 32 extending diagonally inward from the door inner side portion 311 of the weather strip base 31 so that the main lip 32 is in close contact with the roof side rail 4.
The sub-rip 33 is protruded from the door outer part 312 of the weather strip base 31 in a diagonal direction outward of the door so as to be in close contact with the back surface 11, which is the door inner side surface of the frame outer part 10 of the door frame 1. Make it stand out.

Both lips 32 and 33 are configured so that the connecting portions of both lips 32 and 33 are reduced to prevent the movement of one lip from interlocking with the other lip and reducing the sealing function of the lip. It is made independent.

However, this door weather strip 30
Since the contact force of the sub-rip 33 to the back surface 11 of the outside part of the frame is weakened, a slight gap is created between the sub-rip 33 and the back surface 11 of the outside part of the frame, and rainwater, car wash water, etc. seep into this gap, and further However, there was a problem in that this water entered the vehicle interior through a small gap between the weather strip base 31 and the retainer 2.

The present invention has been made to solve the above-mentioned conventional problems, and has a simple structure that allows the subrip to be brought into pressure contact with the back surface of the outer side of the door frame when the door is closed, thereby closing the gap. The purpose of the present invention is to provide a door weather strip for automobiles.

In this invention, the door frame of the door sash part is
It has a frame outer part that extends in a vertical direction, which is the door height direction, and a retainer that extends in a substantially horizontal direction toward the inside of the door at approximately the center of the frame outer part,
A weather strip base held by the retainer of the door frame, a hollow main lip that protrudes diagonally inward from the inside part of the door in close contact with the vehicle body surface, and a weather strip base part held in the retainer of the door frame; In a door weather strip for an automobile, the door weather strip is provided with a sub-rip that protrudes in a direction and is in close contact with a back surface which is an inner side surface of the door on an outer part of the frame of a door frame, and either one of the main lip and the opposing surface of the sub-rip A protrusion is formed on one side of the door frame at a portion corresponding to the back surface of the outer frame portion of the door frame, and when the door is closed, the sub-rip is brought into pressure contact with the back surface of the outer frame portion of the door frame through this protrusion portion. In this way, the above objectives are achieved.

An embodiment of the present invention will be described below with reference to the drawings.

Figure 1 is a perspective view showing the entire car body, Figure 2 is a perspective view showing the entire body of the car.
The figure is an enlarged sectional view of the portion corresponding to the line A-A in Figure 1, showing an embodiment of the automobile door weather strip according to the present invention, and Figure 3 is an enlarged sectional view of the automobile door weather strip according to the present invention. FIG. 3 is a cross-sectional view showing the free state of the example.

As shown in the figure, in this embodiment, a door frame 1 of a door sash part fixed to the upper part of the door body has a frame outer part 10 extending in the vertical direction, which is the door height direction, and a frame outer part 10 extending in the vertical direction, which is the door height direction. a weather strip base 31 held by the retainer 2 of the door frame 1;
A hollow main lip 32 that protrudes diagonally inward from the door inner part 311 of the base 31 and comes into close contact with the vehicle body surface, and a door outer part 3 of the base 31
In the automobile door weather strip 3, the main lip 32 is provided with a sub-rip 33 that protrudes obliquely outward from the door and is in close contact with the back surface 11, which is the inner side surface of the door in the frame outer part 10 of the door frame 1. A protrusion 5 is integrally formed in a portion of the door frame 1 corresponding to the back surface 11 of the outer side of the frame on the surface facing the subrip 33.

That is, on the surface facing the sub-rip 33 of the main lip 32, the protrusion 5 does not protrude from the upper end of the back surface 11 of the outer frame portion 10 of the door frame 1, and extends beyond the upper end of the back surface 11 of the outer frame portion at a position below this upper end. It is provided protrudingly within the range in the vertical direction.

Further, it is preferable that the protruding portion 5 protrudes at a height corresponding to the seal bead 6 provided on the side of the sub-rip 33 on the side that is in close contact with the back surface 11 on the outer side of the frame.

In addition, the reference numeral 7 in the figure indicates a drip channel, and the reference numeral 8 indicates a drip molding.

According to this embodiment, as the main lip 32 is pressed against the roof side rail 4 and deformed when the door is closed, the protrusion 5 moves in the direction of the sub-rip 33 and presses the sub-rip 33 with its tip. It can be brought into strong pressure contact with the back surface 11 of the frame outer part of the door frame 1.

In particular, the protrusion 5 protruding from the surface of the main lip 32 facing the sub-rip 33 is located on the outer side of the frame at a position below the upper end of the back side 11 of the outer side of the frame, which corresponds to the back side 11 of the outer side of the frame. Within the vertical range of the back surface 11 of
That is, the sub-rip 33 and the back surface 11 of the outer part of the frame.
Since the protrusion is provided protrudingly in the area where the protrusions 5 overlap, the pressing of the sub-rip 33 by the tip of the protrusion 5 ensures strong pressure contact of the sub-rip 33 to the back surface 11 of the outer side of the frame. can.

Therefore, there is a sufficient close contact between the sub-rip 33 and the back surface 11 of the outer side of the frame.

If the position where the tip of the projection 5 contacts the sub-rip 33 corresponds to the seal bead 6, the sealing effect will be further improved.

Since the present invention is configured as described above, it has an excellent effect of preventing rainwater, car wash water, etc. from entering the vehicle interior through the door frame of the vehicle.
