[0001] This application is related to and claims priority from Japanese patent application No. 2002-285921, incorporated herein by reference.
[0002] 1. Field of the Invention
[0003] The present invention relates to a side moulding for mounting on an exterior side surface of a body or door of a motor vehicle.
[0004] 2. Description of Related Art
[0005] Conventionally, side mouldings have been mounted on exterior side surfaces of a body and doors of a motor vehicle by clips or double-sided adhesive tapes.
[0006] In the case of a side moulding being mounted by clips, protruding clip-attaching parts are provided in a rear surface of a main body of the side moulding, and the clips are fitted to the clip-attaching parts, or welded thereto using ultrasonic waves, thereby attaching the clips to the side moulding. Then, the clips attached are inserted into clip holes provided in the body or door of the motor vehicle, thereby mounting the side moulding on the motor vehicle. One example of such a conventional side moulding is disclosed in Publication of Japanese unexamined patent application No. 2000-6731, on pages 3 to 4, and in FIG. 2.
[0007] In the case of a side moulding being mounted by double-sided adhesive tapes, they have been previously bonded to longitudinally extending side edges of a rear surface of a main body of the side moulding, and after peeling releasing sheets from the double-sided adhesive tapes, they have been pressed on the body or door of the motor vehicle, thereby bonding the side moulding to the motor vehicle.
[0008] In order to mount the side moulding by only the double-sided adhesive tapes, they must have a considerably large contact area against the body or door of the motor vehicle. But, since the double-sided adhesive tapes are expensive, manufacturing costs of the side moulding are caused to increase.
[0009] In addition, in order to effect a sufficient bonding force, the double-sided adhesive tapes must have a considerably large width so that it is difficult to reduce the width of the side moulding. Consequently, the side moulding cannot be freely designed, and the weight of the side moulding increases.
[0010] Furthermore, where the side moulding is mounted by the double-side adhesive tapes, a mounting area of an exterior side surface of a body or door of the motor vehicle is required to be clean and free from dust, oil or the like, and is also required to be free from surface irregularities. Consequently, the control of the assembling process of the motor vehicle becomes complicated.
[0011] In order to solve these problems, the side moulding has been mounted by clips. But, when the number of the clips is too many, manufacturing costs increase, and time and labor for mounting the side moulding also increase. Accordingly, the clips have been attached to the rear surface of the side moulding at some long distances.
[0012] Where the side moulding is mounted on the body or door of the motor vehicle by the clips attached to the rear surface of the side moulding, there may occur a gap between the side moulding and a facing exterior side surface of the body or door between adjacent clips due to the curving and the surface irregularities of the body or door of the motor vehicle.
[0013] When a gap exists between the side moulding and the body or door, noise is generated during the running of the motor vehicle, or upon the opening and closing of the door.
[0014] Recently, for reducing the weight of the motor vehicle, body panels and door panels have been made thinner. In this case, when the door is closed hard, for example, noise may be frequently generated.
[0015] Under these circumstances, as shown in
[0016] In another example, a soft member is formed along each of side edges of a main body of a side moulding with a duplex extrusion process for achieving a shock absorbing operation.
[0017] In the case of the side moulding
[0018] In addition, for ensuring sufficient bonding strength of the double-sided adhesive tapes
[0019] In order to bond the double-sided adhesive tapes
[0020] Where the soft member is formed along each of the side edges of the main body of the side moulding by a duplex extrusion process, a border line between the soft member and a hard member appears along each of the side edges of the side moulding, thereby deteriorating the appearance of the side moulding, and increasing manufacturing costs.
[0021] Accordingly, it is an object of the present invention to provide a side moulding which is readily manufactured and mounted on an exterior side surface of a body or door of a motor vehicle, and is prevented from generating noise in a gap between the side moulding and the exterior side surface of the body or door during the running of the motor vehicle, and upon the opening and closing of a vehicle door.
[0022] In accordance with the present invention, the side moulding for mounting on an exterior side surface of a body or door of a motor vehicle includes a main body, clips for mounting the main body on the body or door of the motor vehicle, and cushion members provided in a rear surface of the main body. Each of the cushion members includes a cushion part for achieving a cushioning operation against the main body, and the body or door of the motor vehicle, and a fitting part for fitting to each of rib parts provided in the rear surface of the main body.
[0023] In accordance with the present invention, the cushion members are provided in the rear surface of the main body of the side moulding. When the side moulding is mounted by the clips, each cushion member is interposed between the main body of the side moulding and the body or door of the motor vehicle, and the cushion part of each cushion member achieves a cushioning operation against the main body, and the body or door of the motor vehicle. Consequently, the side moulding is brought into close contact with the exterior side surface of the body or door, thereby preventing the side moulding from vibrating during the running of the motor vehicle and upon the opening and closing of the vehicle door. Accordingly, there is not generated noise around the side moulding.
[0024] In addition, since each cushion member is fitted to each rib part provided in the rear surface of the main body of the side moulding, the cushion members can be readily attached to the main body, thereby improving the productivity of the side moulding.
[0025] In a preferred embodiment of the present invention, each rib part is provided along each of longitudinally extending side edges of the rear surface of the main body over the approximately entire length thereof, and each cushion member is attached to each rib part thus provided.
[0026] With this arrangement, since each rib part is provided along each of the longitudinally extending side edges of the rear surface of the main body over the approximately entire length thereof, and each cushion member is attached to each rib part, each cushion member can be attached along each of the side edges of the rear surface of the side moulding over the approximately entire length thereof. Accordingly, the side moulding can be brought into close contact with the exterior side surface of the body or door securely with a reaction force exerted by each cushion member that is provided along each of the side edges of the side moulding. Consequently, the side moulding is prevented from vibrating during the running of the motor vehicle and upon the opening and closing of the door, thereby preventing the generation of noise around the side moulding.
[0027] In another preferred embodiment, each rib part provided along each of longitudinally extending side edges of the rear surface of the main body over the approximately entire length thereof is composed of two ribs, and the fitting part of each cushion member is fitted between the two ribs of each rib part.
[0028] With this arrangement, since each rib part is composed of two ribs, and the fitting part of each cushion member is fitted between two ribs of each rib part, by merely inserting each cushion member between two ribs of each rib part, the cushion members can be attached to the main body of the side moulding securely, and accordingly, the side moulding can be readily manufactured, and the cushion members can be securely held by the main body.
[0029] In still another preferred embodiment, the cushion part of each cushion member includes a lip extending in such a manner as to be fitted between each of the longitudinally extending side edges of the main body and the body or door of the motor vehicle.
[0030] With this arrangement, since the cushion part includes a lip extending in such a manner as to be fitted between each of the longitudinally extending side edges of the main body and the body or door of the motor vehicle, a gap can be prevented from occurring between each of the longitudinally extending side edges of the main body and the body or door of the motor vehicle, thereby preventing the generation of such noise as to have been encountered when the side edges of the conventional side moulding come into contact with a body or door of a motor vehicle.
[0031] In a further preferred embodiment, the cushion part and the fitting part of each cushion member are composed of different materials from each other.
[0032] With this arrangement, since the cushion part and the fitting part are composed of different materials from each other, the fitting part may be composed of a material having strength and elasticity required to be fitted to each rib part, whereas the cushion part may be composed of a material having flexibility and elasticity. Accordingly, the materials for the cushion part and the fitting part of the cushion member can be selected freely.
[0033] In a still further preferred embodiment, the cushion part and the fitting part of each cushion member are composed of the same material as each other.
[0034] With this arrangement, since the cushion part and the fitting part are composed of the same material as each other, the cushion part and the fitting part can be strongly joined to each other.
[0035] In a further preferred embodiment, the fitting part of each cushion member is composed of a material having a greater hardness than that of a material of the main body of the side moulding.
[0036] With this arrangement, since the fitting part has a greater hardness than the main body of the side moulding, the cushion members can be securely attached to the rib parts provided in the main body.
[0037] In a still further preferred embodiment, each clip is arranged so as to exert a reaction force of 0.5 N to 50 N when the side moulding is mounted on the body or door of the motor vehicle.
[0038] With this arrangement, since the reaction force of each clip, which is exerted when the side moulding is mounted on the body or door, ranges from 0.5 N to 50 N, a mounting force required for mounting the side moulding to the body or door of the motor vehicle can be reduced, thereby facilitating the mounting work of the side moulding.
