Embodiments of the present invention will be described below with reference to FIGS.

In FIG. 1, 1 is a slide door, 2 is an inner panel of the slide door 1, and 3 is an inner panel 2 of the slide door 1.
Is a door trim that is assembled to the surface of the vehicle interior side, and the door trim 3 is usually formed by integral formation of synthetic resin.
Reference numeral 5 denotes a remote device attached to the inner panel 2 inside the slide door 1. A shaft 6 of the remote device 5 penetrates through a hole of the inner panel 2 and projects into the vehicle compartment, so that the shaft 6 is inserted into the vehicle interior. A handle shaft portion 6a is bent and formed on the projecting portion. When the remote device 5 is attached, the handle shaft portion 6a is substantially along the surface of the inner panel 2 on the inside of the vehicle compartment, and the handle shaft portion 6a is rotated by a rotating operation. The one-way rotation of 6 causes the unlatching operation of the door latch device of the slide door 1 via the remote mechanism (not shown) of the remote device 5.

An inner handle portion 4 is integrally formed with the synthetic resin door trim 3, and when the door trim 3 is assembled to the inner panel 2, the inner handle portion 4 overlaps the handle shaft portion 6a, By fitting and engaging the handle shaft portion 6a with the clip portion 42 integrally formed on the back side of the handle portion 4, the inner handle portion 4 is coupled in a state of surrounding the handle shaft portion 6a from the vehicle interior side, and the inner handle portion The handle shaft portion 6a is rotated by the rotation operation of the portion 4, the unlatching operation of the door latch device is performed as described above, and the door can be opened.

More specifically, a window hole portion 31 is formed in the door trim 3, and when the door trim 3 is assembled to the inner panel 2, the shaft 6 and the handle shaft portion 6a of the remote device 5 have the window hole portion 31. The inner handle portion 4 is projected and extended from the one end portion of the window hole portion 31, that is, the position very close to the rotation center line of the shaft 6 to the inside of the window hole portion 31. Is integrally formed into a shape, and the base end portion of the inner handle portion 4, that is, the window hole portion 31
A neck portion 41 is formed in a continuous portion of the inner handle portion 4 and the inner handle portion 4 around the rotation center line of the shaft 6 as a center. It can be rotated within the range.

On the back side of the inner handle portion 4, two clip portions 42 into which the handle shaft portion 6a is fitted and locked and a plurality of rib portions 43 for reinforcement are integrally formed. The handle shaft portion 6a is fitted into and locked by the handle shaft portion 6a.
The inner handle portion 4 and the inner handle portion 4 are coupled to each other while the handle shaft portion 6a is held on the back side of the inner handle portion 4, and the shaft 6 is moved by moving the inner handle portion 4 from the vehicle interior side, for example, in the rearward direction. When the door latch device is rotated to release the latch, the slide door 1 is slid backward and opened, and when the hand is released from the inner handle portion 4, the inner handle portion 4 is returned to the shaft by the return spring (not shown) of the remote device 5. 6 and handle shaft 6
It returns to the original position integrally with a. Also, the inner handle portion 4
The slide door 1 can be closed by pushing in the forward direction.

A cover plate 7 is stretched at a portion of the inner panel 2 corresponding to the window hole portion 31 so that the inner panel 2 is not directly exposed to the inside of the vehicle, but the cover plate 7 is not always required. It is not necessary and may be omitted.

The neck portion 41 of the inner handle portion 4 is designed so that the inner handle portion 4 can be easily rotated about the rotation center line of the shaft 6 by bending deformation of the neck portion 41 and can withstand repeated use for a long period of time. It is necessary to construct a structure having appropriate flexibility and durability. A specific configuration example is shown in FIGS. 2 (A), 2 (B) and 2 (C).

That is, in FIG. 2, (A) shows the window hole portion 31.
Shows an example in which slits 3a having a predetermined depth are formed on the left and right sides of the neck portion 41 of the neck portion 41, and (B) shows an example in which slits 4a having a predetermined depth are formed on the left and right sides of the neck portion 41 root portion of the inner handle portion 4. By forming the slits 3a or 4a in this manner, the substantial length of the neck portion 41 is lengthened, and thereby the flexibility and durability of the neck portion 41 are improved. FIG. 2C shows the neck portion 41 of the window hole portion 31.
An example in which the flexibility and durability of the neck portion 41 are further improved by forming the slits 3a having a predetermined depth on the left and right of the base portion and forming the void portion 41a in the neck portion 41 is shown.

All of the three examples shown in FIG. 2 are structural examples of the neck portion 41 when the door trim 3, the inner handle portion 4 and the neck portion 41 are integrally injection-molded with a relatively hard synthetic resin material. In this case, the thickness of the neck portion 41 in the bending direction is reduced to some extent and the length thereof is increased to improve flexibility and durability.

In FIG. 3, the neck portion 41 and its peripheral portion are integrally formed of a soft synthetic resin S different from the hard synthetic resin R of the door trim 3 and the inner handle portion 4 by double injection molding or insert injection molding. An example is shown. By thus forming only the neck portion 41 and its peripheral portion with the soft synthetic resin S, the flexibility and durability of the neck portion 41 can be further improved as compared with the case of the embodiment of FIG.

[0017]

As described above, in the door trim formed by injection molding of synthetic resin, the inner handle portion is integrally formed with the door trim so that it can be rotated by the bending deformation of the neck portion of the door trim. The handle shaft portion formed by bending the shaft of the door opening / closing remote device attached to the panel is engaged with the inner handle portion so that the handle shaft portion and the inner handle portion rotate integrally. By adopting a combined structure, the inner handle as an independent part and all accessories such as escutcheons and clips necessary for its mounting are unnecessary, and the number of parts is greatly reduced and the logistics and management man-hours are reduced accordingly. After assembling the door trim to the door inner panel, the inner trim integrated with the door trim Since the inner handle part and handle shaft part are combined and assembled by almost one-touch work by simply pressing and engaging the handle part with the handle shaft part located on the back side, the number of man-hours for fitting work and maintenance / removal work is remarkable. It is possible to achieve simplification and significant cost reduction, and in combination with the fact that the inner handle part is integrated with the door trim, it is possible to obtain design fun, and it brings a great practical effect. I will get it.
