Description

  The present invention relates to a vehicle seat to which a resin molded product that can prevent a sheet cover end portion around a resin molded product mounting portion from protruding from a peripheral portion of the resin molded product and a production method thereof.

  2. Description of the Related Art Conventionally, a passenger door for a two-door vehicle is usually provided with an operation lever for moving the seat back forward for the purpose of getting on and off the rear seat user. In recent years, this operation lever is generally attached to the side of the shoulder portion on the door side of the passenger seat in consideration of operability and securing of the interior space. The operation lever has a structure in which a resin molded product called a bezel in which a lever guiding long hole is formed is attached to a sheet, and the operation lever is slid along the long hole.

As a mounting structure for such a resin molded product, a seat cover end portion around the resin bezel mounting portion is fixed by pressing on the back side of the resin bezel, or a thick cushion layer is interposed and fixed. Etc. are known (see, for example, Patent Document 1). However, in the conventional case, when a finger or the like is applied to the periphery of the resin bezel mounting part during the reclining operation of the seat or when the passenger gets on and off, a tensile force is applied to the seat cover, and as shown in FIG. There was a problem that the edge of the peripheral seat cover protruded from the peripheral edge of the resin bezel. Furthermore, since the end portion of the sheet cover that has once protruded does not automatically return to the original state, it has been in a state of protruding and has a problem that the appearance quality is remarkably deteriorated.

  The present invention solves the problems as described above, and a vehicle seat capable of preventing a sheet cover end portion around a resin molded product mounting portion such as a resin bezel from protruding from the peripheral portion of the resin molded product, The present invention has been completed for the purpose of providing a production method capable of efficiently and inexpensively producing a vehicle seat to which such a resin molded product is attached.

  The present invention made to solve the above-mentioned problems is a vehicle seat in which a resin molded product obtained by installing a resin molded product on a part of a sheet in which a urethane pad is covered with a skin cover is attached, and the resin Legs that can be locked to the seat frame are projected on the back side of the molded product, while the skin cover and urethane pad are formed with slits into which the legs can be inserted, and around the slits of the skin cover. Reinforcement cloth and hot melt film are sequentially laminated on the back side of the part, and the skin cover or reinforcement cloth and urethane pad in the periphery of the slit are bonded and integrated by the hot melt film heated and melted. According to a first aspect of the present invention, there is provided a vehicle seat having a resin molded product attached thereto.

  The reinforcing cloth is preferably a canvas having a smaller area than the hot melt film, and the canvas is preferably integrated with the skin cover by sewing.

  Also, a method for producing a vehicle seat in which a resin molded product obtained by installing a resin molded product on a part of a sheet in which an ureta pad is covered with a skin cover is attached, and the rear surface of the peripheral portion of the slit for mounting the resin molded product Laminate cloth and hot melt film are sequentially laminated on the side, sewn together on the skin cover, then the urethane pad is covered with the skin cover, and the resin molded product is attached through the slits from the top of the skin cover. Finally, finish steam is blown from the surface side to the periphery of the resin molded product, and the hot melt film is heated and melted to bond and integrate the skin cover or reinforcing cloth around the slit to the urethane pad. According to a third aspect of the present invention, there is provided a method for producing a vehicle seat having a resin molded product attached thereto.

In the vehicle seat of the present invention, a reinforcing cloth and a hot melt film are sequentially laminated on the back side of the periphery of the slit of the skin cover, and the hot melt film heated and melted is covered with the skin cover or the reinforcing cloth in the periphery of the slit. Since the urethane pad is bonded and integrated, even if a finger is applied around the resin bezel mounting part and a tensile force is applied to the seat cover, the edge of the seat cover around the resin bezel mounting part is resin. Protruding from the peripheral edge of the bezel can be prevented.
In addition, when canvas is used as the reinforcing cloth, the periphery of the slit can be reliably reinforced by the strength of the canvas, and heat transfer for melting the hot melt film can be cut off because of the breathability. The hot melt film can be satisfactorily melted by heating and can be sufficiently impregnated into the skin cover or the canvas.

  In addition, the vehicle seat production method of the present invention is similar to the conventional method. After the seat assembly is completed by attaching the resin molded product through the slit portion from above the skin cover, the finish steam is finally applied from the surface side to the resin molded product. Because the hot melt film is heated and melted and the reinforcing cloth or the skin cover is impregnated into the periphery of the slit, the skin cover or the reinforcing cloth around the slit can be bonded and integrated with the urethane pad. It is possible to efficiently and inexpensively produce a vehicle seat that can prevent the resin bezel from protruding from the peripheral edge of the resin bezel. In addition, since the hot melt film, the reinforcing cloth, and the skin cover are sewn together, resin molding It is excellent in attachment to the product.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
The drawings show a case in which a resin vessel for forward operation is attached as a resin molded product to the side of the shoulder portion of the passenger seat, FIG. 1 is a perspective view showing the seat, and FIG. 2 is a perspective view showing the seat frame. 3 is a cross-sectional view of the main part showing a state where the resin molded product is attached, FIG. 4 is a cross-sectional view of the main part showing the mounting part of the resin molded product, and FIG. 5 is a front view showing the mounting part of the resin molded product. is there.
In the figure, 1 is a seat comprising a seat back 1a and a seat cushion 1b, and 2 is a resin molded product (in the case of illustration, a resin vessel for forward operation) attached to the side of the shoulder of the seat back 1a. The outer surface of the urethane pad 10 is covered with a skin cover 11.

As shown in FIG. 2, a guide groove 2a of the operation lever 3 is formed in the resin molded product 2, and a plurality of leg portions 2b that can be engaged with the seat frame 4 protrude from the back surface side. . Further, a receiving member 5 having a hole 5a is provided on the side surface of the shoulder portion of the seat frame 4, and a convex portion 2c formed at the distal end of the resin molded product 2 is a receiving member 5 as shown in FIG. The resin molded product 2 is fixed and held by engaging with the hole 5a.
Meanwhile, as shown in FIGS. 3 to 4, the skin cover 11 and the urethane pad 10 are formed with slits 11 a and 10 a into which the leg portions 2 b can be inserted, respectively. On the back side, a reinforcing cloth 12 and a hot melt film 13 are sequentially laminated.

And in the sheet | seat of this invention, when the hot melt film 13 heat-melted impregnates the skin cover 11 or the reinforcement cloth 12, the skin cover 11 or the reinforcement cloth 12 of a slit peripheral part adhere | attaches and integrates with the urethane pad 10. It has become a state.
As a result, during the reclining operation of the seat or when the occupant gets in and out, a tensile force is applied in the direction of further tearing the slit portion of the skin cover 11 by placing a finger or the like around the resin bezel mounting portion, and the peripheral edge of the slit of the skin cover 11 Even if the portion protrudes to the outside of the resin molded product 2, the skin cover 11 is bonded and integrated with the urethane pad 10, so that the skin cover 11 is automatically restored when the urethane pad 10 is elastically restored. Therefore, the protrusion of the skin cover does not occur. Moreover, if the said tensile force is small, it will be suppressed that the slit peripheral edge part of the skin cover 11 adhere | attached and integrated with the urethane pad 10 protrudes outside the resin molded product 2 with the elastic force of the urethane pad 10. FIG.

  As the reinforcing cloth 12, a vinyl chloride sheet has been conventionally used. However, in the present invention, as described later, it is necessary to pass the finishing steam in the production process, and the hot melt film 13 which is heated and melted is impregnated. The canvas is optimal because of the necessity and the increased strength around the slit. This canvas is a fabric used for ship sails, tents and the like, and is made of cotton yarn or hemp yarn.

Next, a method for producing a vehicle seat according to the present invention will be described.
First, a laminate of the reinforcing cloth 12 and the hot melt film 13 is prepared by sewing (temporary sewing), and the reinforcing cloth 12 and the hot melt film are provided on the back side of the slit peripheral portion for attaching the resin molded product of the skin cover 11. 13 are sewn so as to be sequentially laminated (main stitching) to form the skin cover 11 (see FIGS. 4 and 5). The slits of the urethane pad 10, the skin cover 11, and the reinforcing cloth 12 are formed in advance at the time of molding, and the slits of the hot melt film can be formed by cutting with a cutter knife or the like. Further, as shown in FIG. 5, the hot melt film 13 is disposed larger outward than the outer periphery of the reinforcing cloth 12.

  Next, according to a conventional method, the ureta pad 10 is covered with the obtained skin cover 11, and then the resin molded product 2 is attached from above the skin cover 11 through the slits 11a and 10a to complete the seat assembly (see FIG. 3). .

Finally, finish steam is sprayed from the surface side to the periphery of the resin molded product 2 to heat and melt the hot melt film 13 and impregnate the reinforcing cloth 12 or the skin cover 11, and the skin cover 11 or the reinforcement around the slit. The cloth 12 is bonded and integrated with the urethane pad 10.
Conventionally, a vinyl chloride sheet has been generally used as the reinforcing cloth 12. However, in the present invention, when the finished steam is sprayed by using the canvas, the hot melt film melted by heating is used as the reinforcing cloth 12 or the skin cover. Thus, the skin cover 11 and the urethane pad 10 can be bonded.

  The sheet obtained in this way is in a state where the skin cover or reinforcing cloth around the slit is bonded and integrated with the urethane pad. Even in the case of adding, it is possible to reliably prevent the end portion of the seat cover around the resin bezel mounting portion from protruding from the peripheral edge of the resin bezel. In addition, since the seat can be produced without changing the conventional equipment, the vehicle seat capable of preventing the end of the seat cover from protruding from the peripheral edge of the resin bezel can be produced efficiently and inexpensively.
