Description

[Detailed description of the invention] Industrial field of application The present invention relates to a trim cover that is formed by integrally joining a skin material, a wading material, and a backing material with an uneven pattern of undulations on the surface. It is.

BACKGROUND TECHNOLOGY In general, when configuring a vehicle seat as shown in FIGS. 4 and 5, the seat skin covering the seat back B and seat cushion S is formed with an uneven pattern on the surface and the skin material 1 and wading are formed. A trim cover is used in which a material 2 and a backing material 3 are integrally joined.

Conventionally, in manufacturing this trim cover, three parts are sewn together using sewing machine stitching or the like, thereby forming the sewn parts as recesses P in an uneven pattern. In this case, it is possible to form a geared pattern in the recess together with the stitching, which is preferable because it creates a sense of luxury, but the work is extremely time-consuming and requires skilled techniques, resulting in high costs.

Alternatively, the skin material 1, wading material 2, and backing material 3 may be crimped and bonded into one body using hot press, high frequency or ultrasonic welding, or pressure bonding using an adhesive. Pressure bonding allows a uniform pattern of protrusions and recesses to be formed accurately without requiring particularly skilled techniques.

Problems that the invention attempts to solve: However, in this pressure bonding, the recesses P
When the skin material 1, wading material 2, and backing material 3 are compressed, they harden and lose their elasticity, which not only gives the seater a feeling of tightness or a foreign body sensation, but also gives a poor feeling when sitting. The curing reduces the tear strength, which causes tearing, and the rounded edges of the recesses look bent, resulting in a lack of flexibility in appearance.

Means for Solving the Problems In the trim cover according to the present invention, the wavy wrinkles extending from the recesses of the uneven pattern to the plane of the protrusions and intersecting the longitudinal direction of the recesses are pressed in the longitudinal direction. It is formed by shaping.

Function In this trim cover, even if the uneven pattern is press-formed using a hot press or welder, the undulating wrinkles extending from the recess to the plane of the convex part and intersecting the longitudinal direction of the recess are Because it is formed in all directions, the expansion and contraction of these wavy wrinkles does not give the sitting person a feeling of stiffness or a foreign body, and the tensile force can be dispersed, preventing the occurrence of tears, etc.
In addition, the wavy wrinkles create a sense of flexibility in terms of appearance.

Embodiments The following description will be made with reference to FIGS. 1 to 3.

This trim cover consists of a skin material 1, a wading material 2, and a backing material 3 that are stacked on top of each other, forming an uneven pattern on the surface, extending to the plane of the convex part in the recess P, and extending in the longitudinal direction of the recess. By shaping the intersecting corrugated wrinkles 4, 4a, and 4b in the longitudinal direction of the recess, the three parts are press-joined together. For the pressure bonding, hot press, high frequency welder, ultrasonic welder, pressure bonding with adhesive, etc. can be applied, and in this pressure bonding, the thickness of the recesses P of the uneven pattern is reduced in the longitudinal direction. By continuously curving the material with small undulations, it can be formed to exhibit wavy wrinkles 4, 4a, and 4b. The wavy shape is formed by carving corrugations W ₁ and W ₂ that match each other on the opposing surfaces of the protrusions of the upper and lower molds C ₁ and C ₂ , and upwardly sloping protrusions A and A on both sides of the corrugation W ₁ ... If the skin material 1, the wadding material 2, and the backing material 3 are crimped between these opposing surfaces, the recess P can be shaped at the same time as it is invaginated.

This trim cover can be used in a conventional manner to cover a cushion pad of a vehicle seat or the like. In this trim cover, when a tensile force is applied due to the load of the occupant when sitting, the convex part of the uneven pattern and the elongation of the material exhibit elasticity against the tension in the X direction. In addition, in response to tension in the Y direction, in addition to the elasticity similar to that in the be able to be distributed to Therefore, even if the recesses P of the uneven pattern are hardened by pressure-bonding the skin material 1, wading material 2, and backing material 3, the seater will not feel a tightness or a foreign body sensation, and there will be no tension. Since the force is not concentrated locally, it will not act as if it would tear the material. Furthermore, this wavy wrinkle 4,4
A and 4b create a flexible appearance.

Effects of the invention As described above, according to the trim cover of the present invention, even if a concave-convex pattern is formed by hot pressing or welding, the feeling of deflection when sitting is improved by giving elasticity to the concave areas, and the feeling of deflection when sitting is improved. This makes it possible to form a seat cover or the like that has good elasticity and does not cause tearing or the like.
