Problems solved by technology

[0003] However, in the case where the peripheral portion of the surface layer of an interior part with an integrated surface layer has a corner, as shown in the above-mentioned patent document, if the rigidity of the peripheral portion is increased, it is difficult for the outer surface of the peripheral portion of the surface layer to follow the direction of the base material at the corner portion. Longitudinal walls are pressed against each other, creating a gap between the two
For this reason, the above-mentioned resin leakage occurs between the outer surface of the peripheral portion of the surface layer and the vertical wall surface of the base material.

Embodiment approach 1

[0036] figure 1 , is a vehicle instrument panel 1 showing an interior member with an integrated surface layer according to Embodiment 1 of the present invention. The instrument panel 1 is composed of an upper panel 3 and a lower panel 5 . The portion of the upper panel 3 excluding the front end edge of the vehicle body constitutes a resin intermediate layer 11 integrally formed between the flexible resin surface layer 7 and the rigid resin base material 9 as shown in FIG. The cushion part 13 of the three-layer structure. The above-mentioned vehicle body front end edge is a single layer where the base material 9 is exposed on the side inside the vehicle, and a front anti-fog nozzle 15 is formed along the vehicle width direction at this position.

[0037] The above-mentioned flexible resin surface layer 7 is formed of a flexible soft material such as vinyl chloride or thermoplastic (olefine), and is molded into a predetermined shape by vacuum forming, long slit forming, or the...

Embodiment approach 2

[0048] Embodiment 2 consists of Figure 8 to Figure 10 express. In Embodiment 1, flat surface portions 27 extending from both ends of the groove 25 extending in the vehicle width direction to the rear of the vehicle body are formed on the base material 9 . Instead of the flat surface, in this embodiment, as Figure 9 As shown, a groove 37 similar to the groove 25 described above is provided on the substrate 9 in such a manner as to connect both ends of the groove 25 . On the other hand, the left and right of surface layer 7, such as Figure 10 As shown (only the left side is shown in the figure), the lower flange is not provided and only the side cover 31 is provided so that it contacts as Figure 8 The side wall surface of the groove 37 of the base material 9 as shown, that is, the cover pressing surface 37a.

[0049] and, if Figure 9 As shown, a scalloped corner portion 29 is formed at a corner portion 28 formed by the cover pressing surface 25a on the front side of th...

Abstract

While a corner part 35 of a skin 7 formed between side covers 30 and 31 has a sector shape, a corner part 29 of a base material 9 also has a sector shape. When resin is charged between the skin 7 and the base material 9, the sector-shaped corner part 35 is bent under a pressure at which the resin is charged to stretch outward, thereby bringing the sector-shaped corner part 35 into absolute contact with the sector-shaped corner part 29 of the base material 9. This prevents resin leakage from between the skin 7 and the base material 9.

Description

technical field [0001] The present invention relates to an interior component with an integrated surface layer, in particular to countermeasures against resin leakage at corners. Background technique [0002] On the fourth page of Japanese Patent Application Laid-Open No. 9-76256 (1997), figure 1 , discloses an interior part in which a resin intermediate layer is integrally formed between a surface layer and a base material, and the surface layer is integrated. In this patent document, the peripheral portion of the surface layer is bent downward to cover the side surface of the resin intermediate layer, and this peripheral portion is formed in such a manner as to be in contact with the vertical wall surface of the base material without gaps. Furthermore, the rigidity of the peripheral portion is improved by providing the thick portion on the peripheral portion of the surface layer, so that the contact between the outer surface of the peripheral portion and the base material...
