BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cover of a slip joint for holding an intermediate portion of a seat belt of a vehicle, and more particularly to a structure for locking a divided cover.

[0002]

2. Description of the Related Art A three-point seatbelt of a vehicle is provided with a slip joint for holding an intermediate portion thereof and changing a path of the seatbelt. As shown in FIGS. Slip joint body 1 consisting of panels
Is an insertion hole 1 through which a seat belt S is inserted.
1, the periphery of the insertion hole 11 is molded with a synthetic resin material 13, and the upper part thereof is supported by the vehicle body via the anchor bolt 6.

A slip joint of this type generally has a mechanism (not shown) for adjusting the position of attachment to the vehicle body around an anchor bolt 6 on the upper part of the main body 1.
Covered with a slip joint cover. The slip joint cover has a divided structure, and includes a lower cover 2A that covers the back side of the main body 1 and an upper cover 2B that covers the front side. The lower cover 2A is provided with a reset button 7 for an attachment position adjusting mechanism.

A guide portion 3 is provided at the upper end of the lower cover 2A.
The upper end of the main body 1 is inserted into this, and the upper end of the lower cover 2A and the main body 1 are engaged with each other. On the other hand, at the lower end of the lower cover 2A, as shown in FIG. 4, a locking portion 4B having a locking claw 41 at its tip protrudes, and is formed at a position corresponding to the locking portion 4B of the main body 1. The lower cover 2 </ b> A is fixed to the main body 1 by inserting the locking claws 41 on one side edge 121 of the slit 12. The left and right side edges of the locking portion 4B are reinforced by forming ribs 42B except for the tip.

[0005] The upper cover 2B locks a plurality of claws 21 formed on the outer peripheral edge thereof with a plurality of locking holes 22 formed on the outer peripheral edge of the lower cover 2A to cover and obscure the surface side of the main body 1. A projection 5 is provided at the lower end of the upper cover 2B, and is inserted into a gap between the locking portion 4B of the lower cover 2A and the other side edge 122 of the slit 12, thereby positioning the upper cover 2B and locking the upper cover 2B. The claw 41 is pressed against one side edge 121 of the slit 12 to serve as a stopper.

[0006]

However, in the conventional structure described above, if the upper cover 2B is detached or the projection 5 is not properly inserted, it is necessary to adjust the height of the mounting position of the slip joint. When the reset button 7 is pressed, the engagement between the locking claw 41 and the slit 12 is disengaged, and the lower cover 2A is lifted up, which may hinder the operation of moving the slip joint.

Therefore, the present invention relates to a slip joint cover which does not float up or come off from the main body even if the upper cover of the slip joint cover comes off or the projection of the upper cover is loosened with the locking claw of the lower cover. It is an object of the present invention to realize a stop structure without increasing the number of parts as compared with the related art.

[0008]

SUMMARY OF THE INVENTION The present invention relates to FIGS.
As shown in FIG. 1, a cover that covers the slip joint body 1 that holds the vehicle seat belt S is composed of a lower cover 2A that covers the back side of the body 1 and an upper cover 2B that covers the front side, and the lower cover 2A has an upper end. Is engaged with the upper end of the slip joint body 1, and the engaging portion 4 protruding from the lower end and having the engaging claw 41 at the tip is inserted into the slit 12 provided in the slip joint body 1 to face the slit 12. The locking claw 41 is locked to one of the side edges 121 to be fixed to the slip joint body 1, while the upper cover 2B is locked to the lower cover 2A and protrudes from the lower edge. The inserted protrusion 5 is inserted into the gap between the locking claw 41 and the other side edge 122 of the slit 12 to prevent the locking claw 41 from slipping out of the slit 12. In the locking structure of the joint cover, the said locking claw 41 is provided with a rib 42 which abuts on the other side edge 122 of the slit 12 in the inserted left and right positions on both sides of the protruding portions 4 in the slit 12.

The locking claw 41 is formed on the leading edge of the flat locking portion 4 so as to rise upward, and is locked to the upper edge 121 of the slit 12. The ribs 42 are made to protrude downward from both left and right ends of the front end edge, and contact the lower edge 122 of the slit 12.

According to the locking structure of the present invention, the mounting position on the vehicle body can be adjusted, and the reset button for the position adjustment operation is effectively applied to a slip joint provided on the lower cover. Since the rib that abuts on the lower edge of the slit on the slip joint body side is formed in the part, the locking claw that locks on the upper edge of the slit comes out of the slit even if the projection of the upper cover comes off the slit Never.

A flat guide portion 3 having an insertion hole 31 protrudes from the inner surface of the upper end of the lower cover 2A at a position corresponding to the extending portion 14 of the main body 1 along the upper edge. Further, as shown in FIG. 2, in particular, FIG. 2B, the slit 1 of the main body 1 is formed on the inner surface of the lower end of the lower cover 2A.
2, a plate-shaped locking portion 4 is protrudingly provided at a position corresponding to 2,
A locking claw 41 is formed on the top edge of the upper surface so as to rise up and lock the upper edge 121 of the slit 12. At the left and right ends of the lower surface of the locking portion 4, ribs 42 extending from the distal edge to the proximal edge are formed to protrude downward.

The lower cover 2A is disposed on the back surface of the main body 1, and is inserted into the insertion hole 31 of the guide portion 3 at the upper end.
The extension 14 at the upper edge is inserted, and the upper end and the main body 1 are engaged and positioned. Then, the locking portion 4 protruding from the lower end of the lower cover 2A is inserted through the slit 12 of the main body 1, and the locking claw 41 at the tip is locked to the upper edge 121 of the slit 12. As shown in FIG. 2 (B), the upper end of the rib 42 is located at substantially the same position in the front-rear direction of the locking surface of the locking claw 41 and the locking portion 4, and the distal edge 421 is located on the base end side. It is an inclined surface that descends obliquely. The height of the tip of the rib 42 is set so that the sum of the height and the thickness of the locking portion 4 is substantially the same as or slightly smaller than the vertical width of the slit 12. Therefore, when the locking portion 4 is inserted into the slit 12, the distal end thereof is locked by the locking claw 41.
Abuts against the upper edge 121 of the slit 12 and bends downward.

When the locking claw 41 passes through the slit 12, the locking claw 41 is locked to the upper edge 121 of the slit 12, and the lower surface of the tip of the rib 42 is fitted to the lower edge 122 of the slit 12. The lower edge of the lower cover 2 </ b> A contacts the upper edge of the mold member 13 at the lower part of the main body 1.

The lower cover 2A has a plurality of collar members 8 attached thereto.
Anchor bolts 6 are passed through the body 1 from the surface side of the body 1 via the ring member 82 and the ring member 71, and the anchor bolts 6 are fastened and fixed to a mounting position adjusting mechanism (not shown) on the vehicle body side to connect the slip joint. The vehicle is supported swingably around the anchor bolt 6.

On the other hand, an upper cover 2B is provided on the upper surface side of the main body 1. Upper cover 2B is lower cover 2
A plate-shaped projection 5 is provided at a position corresponding to the slit 12 in a container body made of a synthetic resin material corresponding to A. The projection 5 has a thickness and a width that can be inserted into a gap between the locking portion 4 of the lower cover 2 </ b> A inserted through the slit 12 and the lower edge 122 of the slit 12. Upper cover 2
B allows the plurality of claws 21 formed on the upper and lower edges of the outer peripheral edge to be locked in the plurality of locking holes 22 formed on the upper and lower edges of the outer peripheral edge of the lower cover 2A, and the projection 5 Is fitted into the slit 12 from below the tip of the locking portion 4 of the lower cover 2A, and is fixed to the lower cover 2A.
The lower edge of the upper cover 2B is the mold member 1 at the lower part of the main body 1.
3. Touch the upper edge. In this manner, the upper part of the main body 1 is covered with the lower cover 2A on the back side and the upper cover 2B on the front side.

According to the above-described structure, since the rib 42 that contacts the lower edge 122 of the slit 12 on the main body 1 is formed in the locking portion 4 of the lower cover 2A, the upper edge 12 of the slit 12 is formed.
For example, the locking claw 41 that locks to 1 may be disengaged when the upper cover 2 </ b> B is disengaged and the protrusion 5 is disengaged from the slit 12.
Even if the projection 5 is not properly inserted, it does not come out of the slit 12. Therefore, even if the reset button 7 is operated, the lower cover 2A does not rise,
It does not hinder the height adjustment of the mounting position of the slip joint.

FIG. 3 shows another locking portion 4A of the lower cover 2A of the present invention. As shown in FIG. 3 (A), the locking portion 4A has a locking claw 41 on the upper edge at the top end of the upper surface as in the previous embodiment, and also has ribs 42 protruding downward on both side edges. A step 43 is formed on the lower surface of the distal end of the locking portion 4A. The distal end edge 422 of the rib 42 is a convex polygonal shape which is almost a curved surface as a whole. Further, as shown in FIG. 3B, the lower edge 122 of the slit 12 of the main body 1 is an inclined surface that rises in the insertion direction of the locking portion 4.

When the locking portion 4A is inserted into the slit 12, the distal end 422 of the rib 42 is guided to the lower edge 122 of the slit 12 while the distal end of the locking portion 4A bends downward.
When the locking claw 41 is locked to the upper edge 121 of the slit 12, the lower end of the leading edge 422 of the rib 42 is engaged with the inclined upper end of the lower edge 122 to prevent the locking claw 41 from coming off. Also,
When the projection 5 of the upper cover 2B is inserted into the gap between the locking portion 4A inserted into the slit 12 and the lower edge 122, the tip of the projection 5 comes into contact with the step 43 and serves as a positioning reference for the projection 5, Excessive insertion and insufficient insertion are prevented, and the positioning of the upper cover 2B is further ensured.
