Abstract

PURPOSE:To ensure the holding of the shape of a door weather strip upon extrusion molding while satisfactorily maintaining the balance of the wall thickness of a stay which partitions a hollow part in a hollow seal from a hollow part for attaching fastener clips, by forming a flexible curved section in the substantial middle section of the stay. CONSTITUTION:A follow part 2a in a hollow seal is partitioned by a stay 4 from an attaching hollow part 3 for attaching fastener clips. In this arrangement, a notch 11 as a flexible curved section is formed in the lower side of the stay 4 in the substantially middle part thereof, having the thickness of the stay in this recess 11 section which is made to be thin. When this door weather strip 10 is attached to a door peripheral part 5 to be abutted against a vehicle opening edge 6, if the gap between the door and the vehicle body becomes narrow due to, for example, errors in assemblying, reaction force by the deformation of the stay 4 is effected to the door. Since the notch 11 section is at first deformed in the stay 4 and then parts other than the notch section are deformed at this stage, the condition of door-closing and as well the characteristics of sealing, when the door is closed, may be made satisfactory.

ールが図られるようになっている。Conventionally, this type of door weather for vehicles (IJ5) has been formed as shown in FIG. That is, in the same figure, 1 is a door weather strip in which a hollow part 2a of a hollow seal 2 and a hollow part 3 for attaching a fastener clip are separated by a stay 4, and the hollow part 3 for attaching a fastener clip is separated from a sash 5 of a door. is attached to. When the door is closed, the hollow seal 2 comes into contact with a door opening edge 6 formed on the vehicle body, thereby achieving a seal between the vehicle body and the door.

。Incidentally, the distance between the door sash 5 in the closed state and the vehicle body opening edge 6 is insufficient due to formation errors and assembly errors of the door and the vehicle body. Therefore, when the gap is small and the door is closed, the stay 4 will also bend and deform as shown in Figure 2, in addition to the almost constant reaction force when the hollow seal 2 deforms. A reaction force occurs when the stay 4 deforms. For example, if the reaction force characteristic (a) at this time is shown by the solid line in Figure 3, it will be deflection and resistance.

が悪くなるという問題点があった。The reaction force of the hollow seal 2 becomes approximately constant at one position, and the reaction force increases rapidly at one position where the stay 4 begins to deform. Therefore, DISI where the reaction force exerted on the middle 9 seal 2 is approximately constant
It is set so that a predetermined distance is provided between the door and the vehicle body at 90 points approximately in the center between h. However, as mentioned above, due to the error between the door and the vehicle body, when the door is closed at a later point, the reaction force increases rapidly, making it difficult to close the door. Therefore, in order to solve this drawback, it is conceivable to reduce the wall thickness of the stay 4 to reduce the reaction force caused by the stay 4, but in this case, the surrounding hanging air seal 2. There was a problem in that the wall thickness balance with the periphery of the inner part 3 for attaching the fastener clip was poor, and shape retention by extrusion molding when forming the door weather IJ knob 1 was poor.

アウェザ−ストリップを提供する伜とを目的とする。In view of the conventional situation, the present invention provides a flexible bending part in the middle part of the stay and reduces the reaction force with this flexible bending part, thereby increasing the amount of error absorption between the door and the vehicle body. An object of the present invention is to provide a door weather strip for automobiles which has good extrusion moldability.

2 is a hollow seal, 3 is a hollow part for attaching a fastener clip, and a hollow part 2a of these hollow seals 2 is shown.
The hollow part 3 for attaching the fastener clip is separated by a stay 4. By the way, the h-stay 4 is used when extruding the door weather strip 10.
The hollow seal 2. has a sufficient wall thickness so as to sufficiently maintain the shape of the hollow seal 2. The thickness balance with the periphery of the hollow part 3 for attaching the fastener clip is maintained.

The stay 4 wall thickness of the 1 forming part is formed thin. Incidentally, even if a part of the stay 4 is formed thin in this way,
Unlike the case where the entire stay 4 is formed to have a thin wall, no problems occur due to extrusion molding.

When it is attached to the vehicle body opening edge 6 and brought into contact with the vehicle body opening edge 6,
If the gap between the door and the vehicle body becomes narrow due to formation and assembly errors between the door and the vehicle body, a reaction force due to the deformation of the stay 4 will act on the door.

The reaction force characteristic (b) at this time is shown by the broken line in FIG.
It will be longer from I to Dt' (D! <Dt'), and the door will be longer by this length.

Even if the door closes poorly because the reaction force is large, the reaction force β is greater than β in the embodiment of the present invention! Characteristic(
As shown in b), the door can be closed in the reaction force section of mb-i, and the closing condition and sealing performance of the door can be improved.

るという優れた効果を奏する。As explained above, the automobile door weather strip of the present invention has a shape in which a hollow seal and a hollow part for attaching a fastener clip are separated by a stay, and a flexible bending part is provided approximately in the middle of the stay. Since the flexible bending portion of the stay deforms the substantially constant reaction force section 1!1 of the reaction force fluctuation occurring on the door weather strip due to the gap error between the door and the vehicle body when the door is closed, It can be increased by this. Therefore, by increasing the allowable distance error between the door and the vehicle body, the door I'
It is possible to improve the closing condition and sealing performance at lj. Furthermore, by forming a flexible bending section approximately in the middle of the stay, it is possible to reduce the reaction force without increasing the thickness of the entire stay, so that the thickness balance of the stay can be improved. This provides an excellent effect in that the shape of the door weather strip can be reliably maintained during extrusion molding.
