Description

  The present invention relates to a tacker stop structure for a vehicle interior product having a skin.

As shown in FIG. 6, the conventional tacker-fixing structure for a vehicle interior product having a skin is formed by winding a skin material 53 around an interior base material 52, and the terminal 53a of the skin material is folded back at a terminal 52a of the interior base material. Some are fixed to the outer peripheral edge of the back surface side 52b of the base material 52. In such a vehicular interior material, the outer peripheral edge of the back surface side 52 b of the interior base material 52 is thickened, and the skin material terminal 53 a is fixed to the thick portion 57 by the tacker needle 59.
According to this technique, the tacker needle 59 is stopped at the thick portion 57, thereby effectively preventing the tucker needle 59 from jumping out to the surface of the interior base material 52 and firmly fixing the skin 54 to the interior base material 52. be able to.

By the way, in recent years, there is a movement to reduce the weight and cost of the interior material for the vehicle, and the production of the interior material for the vehicle by thinning and high cycle molding is required. However, when the tacker needle stopper is thicker than the general part, deformation due to heat shrinkage such as sink marks and warpage occurs, which has been an obstacle to high cycle molding and thinning.

  It is an object of the present invention to provide a reliable and robust vehicle interior tucker stopper structure that prevents deformation of sinkers and warps and the like, and eliminates the floating of the tucker needle when the tucker needle is fixed to a base material. And

  In order to achieve the above object, an invention according to claim 1 of the present application is directed to a vehicle interior product in which an outer skin is tackered to a resin base body, and the resin base body has a general part and a tacker stop part The tacker stop portion is a vehicle interior product tacker stop structure having a positioning protrusion of a tucker needle punch and a tucker needle receiving rib.

  According to the first aspect of the present invention, the positioning protrusions and the tucker needle receiving ribs of the tacker needle punching machine of the tacker stopper are both rib-shaped. Therefore, even if the general part is thinner than the tacker stop part, the occurrence of deformation such as sink marks and warpage can be effectively suppressed, and the tucker needle receiving part where the tucker needle pierces is given an appropriate thickness. The tucker needle never penetrates the skin. In addition, the tucker can be positioned, and when the tucker is hit, it prevents the tucker needle from being loosened or suspended in the air due to variations in the position where the operator hits the tucker needle. Can be stopped.

  Furthermore, the invention according to claim 2 is characterized in that the positioning protrusion has a height higher than that of the tucker needle receiving rib.

  According to invention of Claim 2, since the said positioning protrusion is shape | molded higher than the Tucker needle | hook receiving rib, it can position easily.

  According to the present invention, even when thinned and thinned, it effectively prevents deformation such as sink marks and warpage, and eliminates floating of the tucker needle when the tucker needle is fixed to the base material. It is possible to provide a tacker stop structure for vehicle interior parts.

  An embodiment in which the present invention is applied to a pillar garnish will be described below.

  This embodiment will be described with reference to FIG. 1 based on a pillar garnish which is an interior product 10 for a vehicle. The pillar garnish that is the vehicle interior article 10 shown in FIG. 1 has a skin 24 on the surface of the resin base body 11. The resin base body 11 has a tacker stopper 14 and a general part 12 for stopping the skin 24 with a tacker needle 19, and the tacker stopper 14 is provided on the entire peripheral edge avoiding the clip part 20. The skin 24 also has cuts to avoid the clip portion 20. The tacker stopper 14 has a positioning protrusion 14a and a tucker needle receiving rib 14b shown in FIG. The distance between the positioning protrusions 14a is 18 mm, and the positioning protrusion 14a, the tucker needle receiving rib 14b, the tucker needle receiving rib 14b, the tacker needle receiving rib 14b, and the positioning protrusion 14a are arranged in this order, and the width is 2.5 mm. The ribs are arranged at intervals of about 2.6 mm. The positioning projection 14a is formed higher than the other tucker needle receiving ribs 14b. Specifically, the thickness of the resin base body 11 is 2.5 mm, and the height of the tucker needle receiving rib 14b formed between the positioning protrusions 14a is 3.5 mm from the resin base body 11, and the positioning is performed. The protrusion 14a is 6.5 mm. The general portion 12 has a skin end portion positioning portion 35, and when the skin 24 is stopped by the tucker needle 19, the skin end portion 24 a of the skin 24 can be stopped according to the skin end portion positioning portion 35.

  Next, the process of winding the skin 24 around the pillar garnish which is the vehicle interior product 10 of the present embodiment will be described. First, the front side of the resin base body 11 of the pillar garnish is covered with a frame-shaped jig (not shown), an adhesive is applied to the exposed portion, and the exposed portion of the adhesive is dried.

  Next, when the resin base body 11 to which the adhesive is applied is placed on a sponge-like jig on which a skin 24 having a thickness of 2 mm is placed and pressed from above, the skin 24 is temporarily fixed to the resin base body 11. The (Refer to FIG. 1) The skin 24 has a cut for avoiding the clip portion 20.

  In a state where the skin 24 is temporarily fixed to the resin base body 11, the skin edge 24a of the skin 24 is aligned with the skin edge positioning part 35, and the tacker 30 is positioned as shown in FIG. 14a, and tucking while pulling the skin edge 24a. FIG. 4A is a top view of the tacker stopper 14 taken along the line aa. The distance between the positioning protrusions 14a is 18 mm, and the covering 24 is 2.0 mm thick, and is made of knitted fabric, polyurethane foam, and nonwoven fabric. Since the tuckering machine has a width of 16.4 mm, as shown in FIG. 3 (a), when the tuckering machine 30 is set, the polyurethane foam of the outer skin 24 is slightly crushed and the side surface between the positioning projections 14a. Since the left and right side surfaces of the tucker driving machine 30 come into contact with each other, the horizontal displacement of the tucker driving machine 30 can be prevented and the tacker stopper 14 can be set.

  The positioning protrusion 14a is formed higher than the other tucker needle receiving ribs 14b. Specifically, the thickness of the resin base body 11 is 2.5 mm, and the height of the tucker needle receiving rib 14b formed between the positioning protrusions 14a is 3.5 mm from the resin base body 11, and the positioning is performed. The protrusion 14a is 6.5 mm. Since the positioning protrusion 14a is higher than the other ribs, the tucker driving machine 30 can be positioned. Therefore, the horizontal displacement of the tucker driving machine 30 is prevented, and the tacker driving machine 30 is placed between the positioning protrusions 14a. Can be set. Therefore, as shown in FIG. 3B, the tucker needle 19 can be securely fixed to the tucker needle receiving rib 14b.

  In addition, you may change embodiment of this invention as follows.

  In FIG. 2, the skin 24 is wound around the entire circumference of the vehicle interior product 10. As shown in FIG. 2, a triangular notch 37 can be formed in the skin 24. The notches 37 are provided at intervals of 10 mm, which is the length of the upper surface of the tucker needle 19, and the notch 37 can be used as a mark even when the outer skin 24 covers the tacker stopper 14 and the positioning protrusion 14a is difficult to grasp. The position of the protrusion 14a can be grasped, and the tacker can be stopped more quickly. (Example 2)

  The tucker needle receiving rib 14b may be formed longer than the positioning protrusion 14a as shown in FIG. Even when the position of the tucker driving machine 30 is shifted in the vertical direction, the tucker needle receiving rib 14b is formed long, so that the tucker needle 19 reliably stops on the tucker needle receiving rib 14b. (Example 3)

  The positioning protrusion 14a may be U-shaped as shown in FIGS. 5 (a) and 5 (b). By adopting the U-shape, the displacement of the tucker driving machine 30 is eliminated, and the tucker needle 19 can be more securely stopped on the tucker needle receiving rib 14b. Example 4

  The positioning protrusion 14a may have a surrounding shape as shown in FIG. By using the enclosure shape, when the tacker hammer 30 is set to the tacker stopper 14, the vertical and horizontal misalignment of the tacker hammer disappears, and the tacker hammer 30 can be securely fixed, and the tacker is more reliably secured. The Tucker needle 19 can be stopped on the needle receiving rib 14b. (Example 5)

  Further, when the positioning protrusion 14a is enclosed, the tucker needle receiving rib 14b may be a cylindrical rib as shown in FIG. 5 (d) or a horizontal rib as shown in FIG. 5 (e). You may make it. Any shape is a shape which can fix the tucker needle 19 easily. (Example 6)

  Further, when the positioning protrusions 14a are provided on the left and right as shown in FIG. 4A, the tucker needle receiving rib 14b has a height of 0.5 mm even when the tucker driving machine is displaced in the vertical direction. Since the tucker needle stops in such a manner as to straddle the needle receiving rib 14b, it is possible to prevent the protrusion to the surface.

  In addition, the tacker stopper 14 may not be provided on the entire periphery of the resin base body 10, and can be provided in a place where it does not deform in accordance with the shape of the resin base body 11. Further, the interval between the positioning projection 14 a of the tacker stopper 14 and the tucker needle receiving rib 14 b can also be provided at an interval that seems appropriate depending on the shape of the resin base body 11 and the type of the tacker hammer 30.
