Embodiment approach 1

[0044] figure 1 and figure 2 The buffer clip shown is installed on the body side member 40 of the door opening and closing part of the automobile ( figure 2 ), to absorb the impact of closing the door member 44. That is, the body side member 40 and the door member 44 correspond to the "fixed member" and the "movable member" of the present invention. In addition, the cushion clip may be attached to the door member 44 (movable member) depending on the location where it is used.

[0045] The structure of the buffer clip is roughly divided into a clip body 10 formed of a hard resin material such as polypropylene (PP) and a buffer body 20 formed of a soft resin material such as an elastic material. Furthermore, the clip body 10 and the shock absorber 20 are integrally joined at the mutual joining portion J by two-color molding. The clip body 10 is provided for attaching the buffer clip to the vehicle body side member 40 , and the buffer body 20 is provided for receiving the d...

Embodiment approach 2

[0055] The cushion clip shown in these figures is equipped with the cushion body 20 of a vertically long shape compared with the cushion clip of Embodiment 1 mentioned above or Embodiment 3, 4 mentioned later. Therefore, the base portion 12 of the clip body 10 has a columnar extension 32 that enters the inside of the buffer body 20, and a plurality of notches 33 ( Figure 7 and Figure 8 ). Each notch 33 becomes an open surface 33 b except for a bottom surface 33 a, and each open surface 33 b is opened on the peripheral surface and the end surface of the extension part 32 .

[0056] In addition, the shock absorber 20 according to Embodiment 2 includes a cylindrical low buffer portion 28 protruding from the top portion 24 . The low cushioning section 28 initially undertakes Figure 6 The door member 44 is deformed, and then the body portion of the shock absorber 20 is deformed to absorb the impact.

[0057] In the joint portion J of the clip body 10 and the buffer body 20 c...

Embodiment approach 3

[0060] In the buffer clip shown in these figures, the concave-convex shape of the base 12 is set by integrally forming the flange 34 protruding from the outer periphery of the base 12 of the clip body 10 . This concave-convex shape creates a step difference between the outer peripheral portion of the base portion 12 and the flange 34, and wraps it with the elastic material that is the material of the buffer body 20 ( Figure 10 ).

[0061] That is, in the joint portion J of the clamp body 10 and the buffer body 20, the elastic material is wound from the surface side of the flange 34 into the back (underside) side ( Figure 10 ). Therefore, not only the mutual contact area of ​​the joint portion J is increased, but also the base portion 12 of the clip body 10 and the bottom portion 22 of the buffer body 20 are physically bonded to further firmly integrate them.

Abstract

The area of contact at a joint section between a clip body and a cushion body is increased to increase adhesive force between the clip body and the cushion body. A cushion clip is, in order to receive movement of a movable member, such as a door, to absorb the impact, provided with a clip body (10) inserted and mounted in a mounting hole formed in either a fixed member or the movable member and also with a cushion body (20) elastically deforming to absorb the impact. The clip body (10) consisting of a hard resin material and the cushion body (20) consisting of a soft resin material are integrally joined together by two-color molding at a joint section (J) between the clip body (10) and the cushion body (20). The clip body (10) at the joint section (J) is provided with a base (12) having entered the cushion body (20), and the base (12) has an irregular surface shape, such as ribs (30), for increasing the area of contact of the base (12) with the cushion body.

Description

technical field [0001] The present invention relates to a cushion clip, in particular, to a cushion clip for receiving the movement of a door member relative to a body side member and absorbing the impact of closing the door member at various opening and closing parts of an automobile. Background technique [0002] As such a buffer clip, for example, the technique disclosed in Patent Document 1 is known. In this technique, a clip body for attaching to a predetermined panel and a shock absorbing body for absorbing shock are provided. Furthermore, the clip body is molded from a thermoplastic resin material, and the buffer body is molded from an elastic material such as rubber, and they are integrally joined during molding. The joint part is a structure in which the disc-shaped base of the clip body is embedded in the inner space of the buffer body.
