DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an assist grip for a vehicle mounted in a vehicle interior and a method for mounting the same.

[0002]

2. Description of the Related Art As a vehicle assist grip, there is a retractable assist grip. This retractable assist grip includes a long grip body having legs at both ends in the longitudinal direction, and a mounting seat to which the legs are rotatably mounted. With the mounting seat attached, the grip body is rotated between a storage position and a use position.

In order to easily and quickly attach the assist grip to the inner panel, for example, US Pat.
There is an assist grip as disclosed in JP-A-322. In this assist grip, a through-hole is formed in the mounting seat main body, and a pair of flexible locking pieces having locking claws at the distal ends project around the through-hole on the back surface of the mounting seat main body.

[0004] The procedure for attaching the assist grip to the inner panel is as follows. A pair of flexible locking pieces are inserted into the attachment holes so that the attachment seats correspond to the attachment holes in the inner panel, and the attachment seat body is attached to the inner panel. With the lock pin inserted into the through-hole of the mounting seat body from the front side, the lock pin is pushed into the through-hole of the mounting seat body by rotating the grip body in the storage direction with the lock pin inserted into the through-hole of the mounting seat body from the front side, By pushing out the space between the flexible locking pieces with a lock pin, the locking claws of each flexible locking piece are locked from the back side to the periphery of the mounting hole of the inner panel, and the inner panel is mounted on the mounting seat body. And a locking claw.

By the way, in the retractable assist grip, the grip body and the mounting seat are separate objects, and are separately carried into the vehicle body assembly line and mounted on the inner panel of the vehicle body. Assembly man-hours increase. Therefore, the lock pin is carried into the vehicle body assembly line in a state where the lock pin is partially inserted into the through hole of the mounting seat body as in the conventional example.

[0006]

However, if the lock pin is partially inserted into the through hole of the mounting seat main body, the lock pin may be inadvertently inserted for some reason before the mounting seat is carried into the vehicle body assembly line. There is a possibility that the lock pin may be completely pushed into the through hole of the mounting seat body, or the lock pin may fall out of the through hole.

When the lock pin is completely pushed into the through-hole, the locking claw has spread beyond the opening of the mounting hole, so that the assist grip can no longer be mounted on the inner panel in this state. The pin has to be pulled out from the through hole, but since the lock pin is pressed into the through hole, the operation of pulling out the lock pin is extremely difficult.

On the other hand, if the lock pin falls out of the through hole, the lock pin may be lost and the assist grip cannot be assembled on the vehicle body assembly line.

[0009] Such a situation hinders the vehicle body assembly line, and therefore should not occur.

SUMMARY OF THE INVENTION The present invention has been made in view of the foregoing, and has as its object to prevent the lock pin from moving to the lock position before the assist grip is carried into the vehicle assembly line. An object of the present invention is to prevent the lock pin from dropping out of the through hole of the mounting seat body so as not to hinder the work of mounting the assist grip to the vehicle body panel.

As described above, according to the present invention, the grip body moves from the use position to the storage position.
For storage-type vehicle assist grips that are biased to rotate
Before attaching the grip body to the mounting seat, insert the lock pin into the through hole of the mounting seat main body and pass the above extended portion through the lock position while pushing out between the locking pieces with the extended portion of the lock pin tip Since the overhang portion passes through the lock position, the movement of the lock pin in the anti-insertion direction is restrained by the tip of the locking piece whose interval is narrowed, and the overhang portion is held at the position passing through the lock position. Before the assist grip is carried into the vehicle body assembly line, the lock pin can be prevented from dropping out of the through hole of the mounting seat body so as not to be lost. Further, since the projecting portion of the lock pin is held at a position passing through the lock position, the space between the locking pieces is narrowed, and the locking pieces can be smoothly inserted into the mounting holes of the vehicle body panel. Therefore, there is no shortage of parts, and it is not necessary to perform a difficult pin pull-out operation, and it is possible to prevent troubles on the vehicle body assembly line. Moreover, after inserting the locking piece of the mounting seat body of the assist grip into the mounting hole of the vehicle body panel, simply turning the grip body to the use position holds the lock pin in the locked position and moves the assist grip to the vehicle body panel. It can be easily installed with one touch.
