CONSTITUTION:The sash locking body 10 is installed to the upper end section of a front pillar 5 as the fringe section 4 of the car-body opening of the door, and the keeper 20 connected or disconnected to the locking body 10 is mounted to the sash 1b corresponding to the locking body 10. The sash locking body 10 is formed by a case 12 fixed into a sealing surface with the door weather strip 9 of an outer panel 5a, a locking piece 14 slidably fitted to the case 12, a spring 16 energizing the locking piece 14 to the sash 1b side and the stopper mechanism 18 of the locking piece 14. The keeper 20 is fixed to the compartment R side section 1'b of the sash 1b, and has a stopper surface 20b regulating movement to the car outside E side of the sash 1b through connection to the constraight surface 14b of the locking piece 14.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a suction door suction prevention device, that is, it prevents a seal failure due to suction movement of the suction door to the outside of the vehicle under the influence of negative pressure during high-speed driving, and the generation of suction noise due to this seal failure. related to a device for

Generally, when a car is running at high speed, a negative pressure area is generated near the upper circumference of the door, and the door sash, along with the door crow, is sucked out to the outside of the car using the door waist as a fulcrum. It is well known that when the seal between the door and the periphery of the door opening on the vehicle body is broken, the air inside the layer is sucked out from the seal leakage, producing a suction sound. Various attempts have been made to address this suction problem. is running out. However, most of them are not practical because the mechanism to prevent suction is exposed to a large extent on the exterior of the car, impairing the quality of the exterior.

Instead, the best thing to do is to increase the strength of the sash itself and to increase the support strength t for attaching it to the sash door body to counteract the movement of the sash.

However, with such countermeasures, the thickness of the sash plate is increased to increase the strength of the lash, and the amount of welding of the sash to the door body becomes longer, which increases the weight of the door. This increase in weight goes against the weight reduction of automobiles due to the current demands for resource and energy conservation, and also causes door hinges, door check devices, etc. to become larger, which has a large negative impact not only on the doors but also on other parts. In addition, the longer welding distance for the satchel to the door body impairs the freedom of layout of various components within the door, deteriorating the door performance itself.

In view of these circumstances, this invention provides a suction prevention device that does not appear on the exterior of the vehicle, has a thinner sash plate thickness than conventional ones, reduces the welding distance to the door body, and contributes to weight reduction with good door layout. The purpose is to provide.

In order to achieve this object, this invention provides a sash lock body at the portion facing the door sash at the peripheral edge of the vehicle body opening around the door, and this sash lock body is interlocked with a keeper protruding toward the door sash side when the door is closed. ShiC
This is characterized in that the suction movement of the door satsume is regulated.

The embodiment shown in the drawings will be explained below. In FIGS. 1 and 2, a door 1 has a door body 1a and a door sash 1b
and the door glass 2 is raised and lowered along the satchel 1b via a glass run 3. The opening peripheral part 4 of the door in the vehicle body is formed with a box-shaped cross section, and the front side is a front pillar 5, the upper side is a roof sight rail 6,
The lower side is composed of a side full 7 and the rear side is composed of a center pillar 8, and a door weather strip 9 seals between the door 1 and the peripheral edge 4 of the vehicle body opening. A sash lock body 10 is installed at the upper end of the front pillar 5 as the peripheral edge of the opening, and a keeper holder that engages and disengages from the lock body 10 is installed on the sash 1b corresponding to this lock body 10.

The sash lock body 10 is fixed to the inside of the sealing surface of the outer panel 5a of the front pillar 5 with the door weather strip 9, and includes a case 12 with a bottom end 121L extending inside the box-shaped cross section 5b, and a case 12 inside the case 12. A lock piece 14 is slidably fitted into the lock piece 14 and has a long hole 14a and a restraining surface 1411.
A coil spring 16, which is a spring biasing toward the b side, and a stopper mechanism 18, which also serves to prevent the lock piece 14 from being removed and restricts the maximum protrusion position, are fixed to the case 12 and intervene in the elongated hole of the lock piece 14. It consists of a lock pin.

On the other hand, the keeper (5)
The clip part 201L is fitted and fixed to the l part l'b,
By engaging with the restraining surface 14b of the lock piece 14, the sash 1b
It has a stopper surface 20b'e that restricts movement of the vehicle toward the outside E side of the vehicle. The lock body 10 and the keypad are arranged along the opening/closing direction (arrow A) of the door 1, and the restraining surface 14b of the lock piece 14 and the stopper of the keeper so as to intersect with the suction direction (arrow B) of the door 1. [20b is formed.

In the same figure, 22 is the outer panel 5a of the front pillar 5.
is attached to the door sash 1b via a resin retainer.
The pillar molding is formed so as to continue roughly smoothly with the outer surface of the front pillar 5. The windshield glass is adhered to the inner panel 5C of the front pillar 5 via an adhesive 5.

With this configuration, the lock body 10 and the keeper face each other in the positional relationship shown in FIG. 2 when the door is closed, and when the door is opened, the door 1 opens and separates in the direction indicated by the arrow. , the lock piece 14 may be arranged so that the keeper l rides on it, or it may be arranged so that it does not contact at all. When driving at high speed, the sash 1b tends to be sucked out toward the outside of the vehicle E as shown by arrow B due to the negative pressure generated near the front upper part of the door 1, but the lock piece 14 of the lock body 10 and the keeper press is the restraint surface] 4b1 stopper surface 20
b abut and engage with each other to restrict the movement of the sash 1b, to prevent the weatherstrip 9 from separating from the front pillar outer panel and causing seal leakage, and to prevent the generation of suction noise. .

Therefore, the restraining surface 141) and the brim surface 20b are formed so as to have little or no effect on the opening operation when the door is opened, and to be firmly engaged during the suction operation.

As described above, according to the present invention, not only can the lock body and keeper prevent the side door from being sucked out and moved, but also the lock body and keeper are not exposed as part of the exterior of the car when the door is closed, so the appearance quality is improved. Significantly improved, and
By reducing the thickness of the satchel and shortening the welding distance with the door body, the strength of the satsch itself and its support, as well as the strength of the support for the satsch door, can be weakened without any problems, improving the door layout, and improving vehicle This can contribute to weight reduction. Although the keeper is shown as being formed separately from the door sash, the protruding portion serving as the keeper may be formed integrally with the door sash when the door sash is molded.

In addition, by incorporating a lock piece that is always spring-biased in the lock body t case as in the embodiment, even if the door installation arrangement is rough, the lock body and keeper can be secured. It is possible to ensure that the door can be opened and closed smoothly, and the door can be opened and closed smoothly.
