Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a belt molding for a vehicle, which is interposed between a window glass and a door body at a lower edge of a vehicle window.

[0002]

2. Description of the Related Art FIG. 5 is a sectional view taken along the line II of FIG. 4 in which a belt molding portion provided on the lower edge of a window of a vehicle door as shown in FIG.
FIG. 6 is an enlarged sectional view of the VI portion of FIG. 5 and 6, the door body is composed of a door panel outer 1 and a door panel inner 2, and the upper edges thereof form the lower edge of the door window portion. Further, a gap 3 is formed between the door panel outer 1 and the door panel inner 2, and a window glass 4 is inserted in the gap 3 so as to slide up and down.

A belt molding outer 5 and a belt molding inner 6 each having a function as a weather strip are attached to the upper edges of the door panel outer 1 and the door panel inner 2 along the edges thereof. Here, the belt molding inner 6 is mounted on the door trim 7 mounted on the door panel inner 2 with an adhesive material or a tacker 8, and a mounting base 9 is projected obliquely upward from the front surface of the mounting base 9. It is composed of two-stage elastic lip portions 10 and 10, and these lip portions 1
A flocked surface 11 is provided on the surface where 0 and 10 contact the window glass 4. In detail, the mounting base 9 of the belt molding inner 6 is mounted on the door panel inner 2 via the reinforcing member 18.

The belt molding outer 5 is mounted on the upper edge of the door panel outer 1 and has an inverted U-shaped cross section.
2 and the lip portions 13 and 1 having a two-stage structure that is elastic and protrudes obliquely upward from the front surface of the mounting base portion 12 and has elasticity.
3, and a flocked surface 14 is provided on the surface of the lip portions 13, 13 that contacts the window glass 4. With such a configuration, the window glass 4 is elastically sandwiched from both sides by the lip portions 10, 10 and 13, 13 of the belt molding inner 6 and the belt molding outer 5, and the belt molding inner 6 and the belt molding outer 5 are elastically sandwiched. The gap between the window glass 4 and the window glass 4 is closed, and the shake of the window glass 4 in the plane direction is prevented.

[0005]

However, the conventional sandwiching of the window glass between the belt molding outer and the belt molding inner is suitable for sandwiching the window glass so as not to hinder the sliding of the window glass. For example, when the window glass vibrates strongly toward the room, such as when the door is closed tightly, the elastic force of each lip is not enough to stop this vibration, and the window glass is used in regulators or motors installed inside the door. There is a problem that a hitting sound is emitted when hitting a device.

The present invention was devised in view of the above problems, and the lip portion of the belt molding has an arcuate shape which is curved and bulged in the direction of the window glass, and when the lip portion is bent, the upper end edge thereof is formed. The upper edge of the lip to further increase the elasticity of the lip, so that the external force from the window glass applied to the lip when the door is strongly closed is received, and the impact caused by the window glass shakes. An object of the present invention is to provide a vehicle belt molding that can eliminate the generation of sound.

[0007]

Therefore, the vehicle belt molding of the present invention is a vehicle belt molding interposed between a door window glass of a vehicle and a door body of the vehicle, and is a base portion to be attached to the door body. A lip portion extending from the lower edge of the attachment base portion and curving and bulging toward the window glass is formed, and a locking edge extending from the upper edge of the mounting base portion and facing the upper edge of the lip portion is provided. The upper end edge of the lip portion is locked to the locking edge by the bending of the lip portion, and a hollow section having a closed cross section is formed between the lip portion and the mounting base portion. Is characterized by.

[0008]

In the above-described vehicle belt molding of the present invention, the upper edge of the lip portion does not normally contact the engaging edge and presses the window glass with a light elastic force. When an external force is applied to the lip part due to the runout of the lip part, the upper edge of the lip part hits the locking edge and a hollow part with a closed cross section is formed, forming a lip part with a strong repulsive elastic force and suppressing the runout of the window glass. To do.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIGS. 1 to 4 show an embodiment of a vehicle belt molding according to the present invention, and FIG. FIG. 1 is a cross-sectional view of the belt molding for the vehicle as seen from the direction of the arrow.
II is an enlarged cross-sectional view of the portion II, FIG. 3 is a deflection characteristic diagram of the lip portion of the belt molding for the vehicle, FIG. 4 is a front view of the vehicle door, and is the same as FIGS. The reference numerals indicate almost the same parts.

In FIG. 1, reference numeral 6 denotes a belt molding inner having a weather strip function which is attached to a door panel inner (not shown) with a door trim 7 interposed therebetween.
The belt molding inner 6 is made of a vinyl chloride or rubber material or the like and is formed of a long elastic product, and the belt molding extends along the length L along the lower edge of the window of the vehicle door as shown in FIG. It is provided on the inner side of part A,
It is configured to close the gap between the door trim 7 and the window glass 4.

Further, the belt molding inner 6 extends from the vertical mounting base 9 mounted on the door trim 7 by the tucker 8 and the lower edge of the mounting base 9 and bulges toward the window glass. A circular arc-shaped lip portion 15 having elasticity, and a locking edge 16 that also extends from the upper edge portion of the mounting base portion 9 and protrudes in the front direction to face the upper end edge 15a of the lip portion 15. These are integrally formed into a longitudinal shape.

Further, the window glass 4 in the lip portion 15
A flocked surface 11 is formed on the surface facing the and so that the window glass 4 is not damaged. The lip portion 15 is not normally engaged with the engaging edge 16 and, as shown by the solid line in FIG.
Is in a floating state, but when pushed by the window glass 4 from the side, the upper edge 15a is locked by the locking edge 1 as shown in FIG.
A hollow section 17 having a closed cross section surrounded by the mounting base section 9 and the lip section 15 is formed as shown in FIG.

As a result, the upper edge 15a of the lip portion 15 is formed.
Is in a floating state, the repulsive elastic force of the lip portion 15 against the external force applied from the lateral direction of the lip portion 15 is weak, and when the lip portion 15 is in the locked state, the repulsive elastic force against the lateral force of the lip portion 15 is applied. The impact resilience is strong. Further, a reinforcing member 18 is interposed between the mounting base 9 of the belt molding inner 6 and the door trim 7, the lower extending portion thereof covers the lower end of the mounting base 9, and the upper extending portion thereof has the locking edge 16 Is formed so as to cover up to the upper surface, and a folded-back portion 18a is formed at the bent portion of the upward extending portion.

With such a structure, the lip portion 15 of the belt molding inner member 6 is in a state where the window glass 4 does not normally swing such as whether the door is closed or opened.
The window glass 4 is lightly sandwiched between a not-shown lip portion on the outer side of the belt molding so that the vertical movement of the window glass 4 is not hindered. When the door is strongly closed and the window glass 4 swings toward the room, the window glass 4 pushes the lip portion 15 and the upper edge portion 15a of the lip portion 15 is pushed.
Abuts the locking edge 16 to form a hollow portion 17 having a closed cross-section, and the lip portion 15 has a strong repulsive elastic force, thereby suppressing the shake of the window glass 4.

That is, as shown in FIG. 3, the deflection characteristic curve c by the main lip portion 15 has a non-linear characteristic in its practical range, and is the same as the deflection characteristic curve d by the conventional lip portion shown in FIG. Compared to those having such linear characteristics, it shows a wide response to the variability of the bending force and the allowable external force. Incidentally, as shown in FIG. 8, if the back surface of the lip portion 15 of the belt molding inner has a hollow closed section (see reference numeral 17) from the beginning,
Not only does it not show such a wide correspondence as described above, but when the belt molding inner 6 is attached to the door trim 7, the tacker 8 cannot be driven in because the lip portion interferes with driving the tacker 8 into the mounting base 9. In the case where the upper end of the lip portion 15 is in a floating state as in this embodiment,
The tucker 8 can be easily driven by opening the upper end of the lip portion 15.

Accordingly, the belt molding inner 6 according to the present invention normally presses the window glass 4 lightly to the extent that it does not hinder its sliding, but when the window glass vibrates strongly, it exerts a strong elastic force. It exerts its effect to prevent the shake of the window glass, and has an effect that the hitting sound is not generated by hitting another object due to the shake of the window glass when the door is strongly closed as in the conventional case.

Further, the structure of the lip portion is the same as the conventional one.
Since it is not a two-stage structure but a curved one-stage structure, there is no inversion of the lip portion, and the manufacturing of the belt molding is easy and the cost is reduced. It is easy to install, which will improve the productivity of the vehicle. In addition, the protrusion of the locking edge 16 reduces the gap between the door trim 7 and the window glass 4 so that the inside of the door cannot be seen. Therefore, the appearance of the belt molding inner portion is improved and dust inside the door is prevented. There is also an effect that can prevent the invasion of.

Further, also in the structure of the lip portion on the belt molding outer side, the effect becomes more remarkable by adopting the above-mentioned configuration. If the reinforcing member 18 that covers the upper end of the lip portion 15 is made of stainless steel or the like and has glossiness, the belt molding portion can be made more beautiful. Also, the belt molding inner 6
A stabilizer (not shown) is provided below the, but the stabilizer can be omitted.

[0019]

As described in detail above, according to the vehicle belt molding of the present invention, in the vehicle belt molding interposed between the door window glass of the vehicle and the door body, A lip portion that extends from the lower edge of the mounting base portion and bulges in the direction of the windowpane is formed, and a locking edge that extends from the upper edge of the mounting base portion and faces the upper end edge of the lip portion is formed. The upper end edge of the lip portion is locked to the locking edge by the bending of the lip portion, and a closed cross-section hollow portion is formed between the lip portion and the mounting base portion. Therefore, at the normal time, the upper edge of the lip part is in a floating state, and it does not interfere with the sliding of the window glass by pressing it against the window glass with a light elasticity, and when the window glass vibrates strongly, The upper edge of the part is in a locked state and the lip part exhibits a strong elastic force The advantage of preventing the occurrence of striking sound due to the vibration of the window glass by restraining the deflection of the glazing.

Further, since the structure of the lip portion of the belt molding is made simple by the one-piece structure, there is an advantage that the manufacturing is easy and the cost is reduced.
