These were placed in several places above and below to restrict the movement of the body.

However, since this conventional restraint device is provided on the surface where the door and the vehicle body face each other, the strength and rigidity of the mounting surface tends to be insufficient. One way to solve these problems is to increase the thickness of the plate or provide reinforcing materials to strengthen the plated surface, but this increases the weight or assembly man-hours, which may impede efforts to reduce the weight of automobiles. This may lead to increased costs due to decreased productivity. Further, the mounting position is also limited, and there is a problem that it is difficult to install it in a location where there is no opposing surface.

The present invention was developed by focusing on the above-mentioned conventional problems, and utilizes a guide bracket to connect and support the sliding door to the vehicle body, and uses the installation site, which is already high in strength and rigidity, as a scaffold, and moreover, it is effective. The purpose of the present invention is to provide a restraining device for an automobile sliding door that restrains the door.

In order to achieve such an object, the present invention provides a restraining device for a sliding door for an automobile, which restrains a door that slides open and close along a guide rail provided on a vehicle body when fully closed, and includes a guide that supports the door. The member includes a roller bracket having a roller that engages with the guide rail and a cylindrical portion formed at one end, a base fixed to the door, and a cylinder of the roller bracket between side plates erected on both sides of the base. The two side plates of the fixing bracket are extended in the direction of the door movement trajectory immediately before fully closing, and a protruding part is formed at the tip of the plate. A striker has a pair of side plates that clamp the plunger when fully closed, and has an engaging pin fixedly installed across the side plates. Notches that fit with the dowel pins are cut symmetrically, resin coating is applied to both side plates forming the protruding portion, and the tips protrude into the notches,
A restraining device for a sliding door for an automobile, characterized in that an elastic stopper whose base end is close to the cylindrical part of the roller bracket is interposed between the both side plates, and the bracket is a fixing bracket for a guide member having high strength and rigidity. The restraint device is firmly held by using it as a foothold, and the door is securely restrained.The plunger and striker make it a compact restraint device, and the elastic stopper acts as a brake to dampen the swinging of the roller bracket when the door is fully closed. Easy to work with, small and functional,
Moreover, it is a restraining device that securely restrains the door.

The present invention will be described below based on embodiments shown in the drawings.

The guide member 1 includes a roller bracket 12 equipped with rollers 11, 11 that are engaged and guided by a guide rail 2 fixed to the vehicle body A, and a fixed bracket 13 having a U-shaped cross section that swingably supports the roller bracket 12. One end of the roller bracket 12 is extended to the tip of the fixed bracket 13, and a curled cylindrical portion 14 for connection is formed. The fixed bracket 13 has a base 15 fixed to the door B by bolts B2, B2, and side plates 16, 16 are erected at both ends of the base 15 in the vertical direction of the vehicle. The roller bracket 12 is supported in a swingable manner by inserting the pin 17 into the cylindrical portion 14 and fixing it across the side plates 16, 16 so that its axis is directed vertically.

The side plates 16, 16 of the fixed bracket 13 are extended in the direction of the door movement trajectory immediately before fully closing, and a pair of latch portions 3 are formed above and below the tips of the side plates 16. A striker 4 is fixedly installed at the opposing position. Striker 4 is
Here, a striker portion 42 having a U-shaped groove cross section is provided on a base 41 which is made to match the shape of the vehicle body A, which is a corner portion, so as to protrude with the groove direction directed toward the protruding portion 3 . The striker portion 42 has a protrusion portion 3 whose inner space between side plates 43, 43 formed in the vertical direction of the vehicle.
The outer width of the side plates 43, 4 is set to be approximately the same as the outer width of the side plates 16, 16, so that they can be fitted together.
3, the engagement pin 4 has an axis facing vertically.
4 is fixed. The striker 4 faces the protruding part 3, and a base 41 is fixed to the vehicle body by bolts 45, 45 at a position where it engages with the protruding part 3 when the door B is fully closed. The plunge part 3 includes both side plates 16,
A forked notch 3 that fits with the engagement pin 44 of the striker 4 at the tip of the portion forming the protruding portion 3 of 16.
1 and 31 are cut symmetrically to each other, and this notch 3
A resin coating 32 is applied to the vicinity of the protruding portion 3 including 1 and 31. Furthermore, both side plates 16, 16
In between, a tip 33 protrudes into the notches 31, 31,
The proximal end 34 is the cylindrical portion 14 of the roller bracket 12.
An elastic stopper 35 is interposed in close proximity to the stopper 35.

In the automobile sliding door restraint device having the above configuration, when the door B is fully closed, the plunger 3 provided on the fixed bracket 13 of the guide member 1 fits into the striker 4 fixedly installed on the vehicle body A. That is,

The door B moves in the fully closing direction along the opening/closing trajectory of the door B while being inserted and held therebetween. Then, the engagement pin 44 of the striker portion 42 enters into engagement with the notches 31 , 31 . As the engagement pin 44 advances, the notch 3
The elastic stopper 35 comes into contact with the tip 33 of the elastic stopper 35 protruding into the inside of the elastic stopper 1, 31, and enters while pushing it. Due to the elasticity of the elastic stopper 35, the force of the closing force of the door B is buffered, and the door B is brought into a fully closed state. The elastic stopper 35 has a tip 33 attached to the engagement pin 44.
is pushed, so the proximal end 34 tends to bulge out. Therefore, the base end 34 is strongly pressed against the cylindrical part 14 of the roller bracket 12 of the guide member 1, and as a result, the cylindrical part 14 rotates as the door B is pulled toward the vehicle body A just before it is fully closed. The dynamic movement is braked, the force of the closing force of the door B is buffered, the door B is held down during closing, and the rattling of the guide member 1 is suppressed. When the door B is closed, the vertical direction of the door B is restrained by the fitting of the side plates 43, 43 of the striker 4 and the side plates 16, 16 of the plunger 3, and the width direction is restrained by the engagement pin 44.
When the notches 31 and 31 fit together, the door is restrained, and when combined with the door lock device, it is restrained in both the front and rear directions.
