The grip portion protrudes toward the inside of the room with a dimension d so as to secure an operation space for the occupant to grip.

Similarly, the assist grip provided on the roof garnish or the front pillar garnish may be set at a position where the grip portion is shifted from an attachment reference line connecting the attachment fixing points due to modeling.

[0007]

As described above, in the door grip 5 or the assist grip described above, the grip portion gripped by the occupant is not located on the mounting reference line, and is mounted and fixed to the panel 6. Since the grip portion is set closer to the room than the point, when the door is opened and closed, when the occupant grasps the door grip 5, or when the occupant grasps the assist grip in a sharp curve, the door grip is provided. There is a problem that a large moment force acts on the door grip 5 or the assist grip, and the door grip 5 or the assist grip is easily wobble, and a satisfactory operation feeling cannot be obtained.

Further, when the door grip 5 and the assist grip are frequently shaken, the tightening of the screws and the like is weakened,
It was pointed out that the mounting was unstable, which further promoted wobble.

In the door grip 5, the terminal 5a of the door grip 5 and the terminal of the armrest 4 of the door trim 1 are set substantially flush.
When the wobble occurs frequently, a step is generated between the surface of the door grip 5 and the surface of the armrest 4, and a disadvantage that the appearance is deteriorated has been pointed out.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and in a grip structure for an interior trim such as a door grip installed on a door trim or an assist grip installed on a pillar garnish, etc. Is not set on the reference mounting line, no wobble occurs during grip operation, satisfactory grip operation can be expected, mounting stability can be maintained well for a long time, and An object of the present invention is to provide a grip structure for an interior trim that can guarantee a good appearance for a long period of time without giving a sense of incongruity.

[0011]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a mounting standard for connecting mounting fixing points set at both ends in the longitudinal direction to a predetermined position on the surface of an interior trim installed in a vehicle body panel. In a grip structure in an interior trim in which the line and the grip portion are set to different lines and the grip portion is set at a position where the grip portion protrudes toward the indoor side from the mounting fixing point, a grip is provided on an embossing portion for mounting the grip to the vehicle body panel. And a rib for preventing slipping is formed.

Here, the interior trim includes a door trim, a rear side trim, a roof garnish, a front pillar garnish and the like. In the grip, the attachment fixing points to the panel are set on both ends in the longitudinal direction, and the grip portion is not usually located on an attachment reference line that connects the attachment fixation points in terms of shape, and the grip is shifted therefrom. In order to secure a space for gripping, the mounting fixing point projects a long mounting embossed portion from the back side of the grip toward the panel side, and trims this mounting embossed interior trim And is fixed to the panel by screws or the like, and inserted into the mounting hole of the panel.

Further, the slip-preventing rib provided on the mounting embossed portion only needs to achieve a stopper function of abutting against the vehicle body panel in order to prevent the grip from falling. Alternatively, a cylindrical or long cylindrical annular rib may be provided around the mounting embossed portion. In the case of setting a long cylindrical annular rib, the position where the mounting hole deviates from the center of the annular rib is set. It is desirable to set to.

Further, the present invention provides a grip structure in an interior trim in which a grip is attached to a predetermined portion of a surface of the interior trim and a terminal portion of the grip is butt-joined to the interior trim, wherein the grip comprises a grip base and a grip. The cover is divided into two parts, and a terminal portion of the grip base and the grip cover is provided with locking means for suppressing mutual peeling.

As is apparent from the above configuration, since the rib for preventing slipping is formed on the embossing portion for mounting the grip, when the gripping portion is not located on the mounting reference line, the gripping operation is not performed. Even if a large moment force is applied, the anti-roll rib abuts against the vehicle body panel and performs a stopper function, so that the grip does not fluctuate in the twisting direction or the like.

Further, by providing a plate-like rib integrally with the mounting embossed portion or by providing an annular rib around the mounting embossed portion, the rigidity can be enhanced and the strength of the mounting portion can be increased.

Further, according to the fourth and fifth aspects of the present invention,
The grip consists of a fixed body consisting of a grip base and a grip cover joined together, and the lower end part of the grip base and the grip cover are firmly joined by locking means, and the grip is swung in the twisting direction. Even in this case, the terminals of the grip base and the grip cover do not come off from each other, so that there is no step between adjacent components.
