Description

[Detailed Description of the Invention] The present invention relates to an improvement of ceiling interior materials for automobiles.

Conventional ceiling interior materials for automobiles use sheets made of synthetic resin materials such as vinyl chloride, leather, or a combination of sheets or leather and bedding material. To install the interior material, the end portion of the interior material body is also wrapped around a retainer made of metal plate material that is fixed to a mounting bracket called a windshield header inner installed in advance on the ceiling of the vehicle body, and is bonded with adhesive. It is common practice to fit the bonded part and the end of the retainer into a clamping member made of a synthetic resin molded product, etc., and it takes skill and effort to attach the interior material main body to the retainer by holding the end without wrinkling. In addition, since it is bonded with adhesive, the adhesive force deteriorates over time, and the retainer made of metal plate rusts and deteriorates, making it impossible to maintain long-term durability. A number of issues remain.

The present invention relates to an automobile ceiling interior material completed with the purpose of solving the above-mentioned problems.As shown in the illustrated embodiment, a thermoplastic synthetic resin is coated on the surface of the retainer main body 20 made of a metal plate material. This is characterized in that the end portion of the interior material main body 4 is integrally welded to one side portion of the retainer 3 on which the layer 1 is laminated.

In the figure, 3' is an interior material attachment part bent and formed at one end of the retainer 3, and 5 is a mounting hole provided in advance on the ceiling part A of the vehicle body to secure the retainer 3 in a stable state. Therefore, one side of the retainer 3 is connected to the other side of the retainer 3 which is formed in the interior material attachment part 3', and in the first embodiment shown in FIG. The retainer 3 is fixed to the mounting socket by a screw serving as a fixture 6 which is inserted through the screw and screwed into the mounting socket, but the second embodiment shown in FIG. In,
The fixing plate portion 5 similar to the first embodiment is adapted to be locked in a locking notch provided in the fitting mouth, and in the third embodiment shown in FIG. A push-button-shaped clip as a fixture 6 is attached to a transparent hole in the fixing plate portion 5 similar to the second embodiment, and the retainer 3 is locked and fixed to the mounting mouth using this clip. In the second and third embodiments shown in FIGS. 2 and 3, a hook portion 7 is bent at the end of the interior material attachment portion 3' of the retainer 3, and the hook portion 7 is attached to the attachment plate. By locking the retainer 3 to the edge of the mouth, the fixation between the retainer 3 and the fitting mouth is made even more accurate, and at the same time, the fixing work with the fixing tool 6 is further facilitated by temporarily fixing the retainer 3 using the hook portion 7. In particular, in the second embodiment shown in FIG. 2, a locking protrusion 8 is press-molded on the hook portion 7, and this locking protrusion 8 is provided on the fitting opening. By being locked into the locking hole 2, the hook portion 7 can be locked to the mounting mouth more accurately.

With this structure, the interior material main body 4, which has a seat or leather made of a synthetic resin material such as vinyl chloride resin or fabric, is towed along the ceiling A of the vehicle body. If the retainer 3 at the end is fixed to the mounting hole provided in advance on the ceiling part A, the interior material main body 4 is stretched under tension due to its elasticity, and the interior work of the ceiling part A is carried out. After the main work is completed, the interior material main body 4
Compared to the case where the retainer 3 is attached directly to the mounting opening, the installation work is extremely easy and a standardized finish can be obtained. A thermoplastic synthetic resin layer 1 such as vinyl chloride resin is layered on the interior material main body 4, and the end portion of the interior material main body 4 is attached to the interior material attachment portion 3' formed on one side of the retainer 3. Since the thermoplastic synthetic resin layer 1 is welded and integrated in advance using a welding method such as a high frequency welding method, the retainer 3 can be integrated extremely firmly compared to the case where the retainer 3 is attached using an adhesive or a clamping member. Since there is no change over time or creep phenomenon, there is no risk of peeling during use, and even though the retainer main body 2 is made of a metal plate and is prone to rust due to water leakage, etc., the surface is made of thermoplastic synthetic resin. Due to the rust-preventing effect of layer 1, there is no deterioration due to rust, so there is an advantage that it can be used for a long time.

Note that the type of thermoplastic synthetic resin forming the thermoplastic synthetic resin layer 1 and the material of the interior material main body 4 are not particularly limited; Seats and leather made of synthetic resin are ideal for increasing welding strength.

Therefore, in order to manufacture such an automobile ceiling interior material, the end portions of the interior material main body 4 are cut in advance according to the shape of the automobile ceiling portion A, and the end portions are mass-produced in advance and placed in the lower mold of a high-frequency welding device. Mass production is easy because all you have to do is attach it to the interior material attachment part 3' of the set retainer 3, apply high frequency, and weld the two parts together. As mentioned above, interior work can be done by fixing the retainer 3 to the ceiling of the car body, so the end part of the interior material body is wrapped around the retainer that is fixed to the mounting bracket and bonded with adhesive, and the part that was rolled and glued is Compared to the interior work in which the ends of the retainer are inserted into the clamping members and attached to the ceiling, skill is not required and the work time is significantly shortened.
Since the two parts are integrated with sufficient strength, the holding member can be used as needed, reducing the number of parts.Furthermore, since no adhesive is used, the working environment can be improved, which has many advantages.

Note that the retainer 3, which is integrally welded to at least one end of the interior material main body 4, should be able to be fixed to the fitting opening only by pushing as shown in the third embodiment. This is preferable for measuring efficiency.

Therefore, the present invention has great practical value as an automotive ceiling interior material that eliminates the problems associated with the installation work of conventional automotive ceiling interior materials.
