JP5225927B2 - Seat cushion structure for vehicle seat - Google Patents

Description

  The present invention relates to a seat cushion structure in a vehicle seat such as an automobile seat.

  Conventional seat cushions for general automobile seats are equipped with a synthetic resin finisher that is separate from the seat cushion itself, and a reclining device, slide rail, lifter, etc. exposed from the side of the seat cushion. These mechanical parts are covered (for example, JP-A-2006-88943).

JP 2006-88943 A

  Therefore, the conventional seat cushion covers the mechanical parts with the finisher to improve the appearance quality of the seat cushion, but the finisher is made of synthetic resin and is against the trim cover made of flexible material such as cloth that forms the outer surface of the seat cushion. It has a different feeling and is subject to design constraints.

  Further, the finisher needs to be attached to the frame of the seat cushion, the upper rail of the slide rail, etc. by pins, hooks, set screws, etc., and there is a problem that requires a lot of man-hours for the attachment.

  Therefore, an object of the present invention is to eliminate problems caused by the synthetic resin finisher disposed on the side lower side of the seat cushion.

  In order to achieve the above object, a seat back structure for a vehicle seat according to the present invention includes a side portion of a trim cover that constitutes a side surface of a seat cushion, and a mechanism component that is exposed from the outside and below the side portion of the seat cushion. The finisher portion to be covered is formed integrally with a molded non-woven fabric impregnated with a synthetic resin and formed into an uneven shape.

  Moreover, you may use the raw material which has the hardness of about 50 or less Shore hardness, and can be sewn instead of the said shaping | molding nonwoven fabric.

  Moreover, it is preferable to provide a groove or a ridge-shaped deflection absorbing portion in the molded nonwoven fabric or the trim cover portion of the material corresponding to the side portion of the trim cover.

  According to the present invention, since the conventional synthetic resin finisher is not used, the conventional finisher mounting operation becomes unnecessary. In addition, since the side portion and the finisher portion of the trim cover of the seat cushion are integrally formed of the molded nonwoven fabric or the material, there is a sense of unity in design and design variations can be expected.

  In addition, by providing a bending absorbing portion in the trim cover portion of the molded nonwoven fabric or material, the bending applied to the seat cushion is absorbed, and deformation of the molded nonwoven fabric or the finisher portion of the material can be prevented.

The perspective view of the seat cushion of the structure which concerns on this invention. The perspective view of the shaping | molding nonwoven fabric used for this invention. XX sectional drawing of FIG.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 shows an automobile seat having a seat cushion structure according to the present invention, in which A and A show the molded nonwoven fabric, and B shows a main part of a trim cover of the seat cushion SC.

As the molded nonwoven fabrics A and A, for example, molded nonwoven fabrics that are impregnated with a synthetic resin and molded into a concavo-convex shape with a press or the like are used.
As shown in FIG. 2, the molded nonwoven fabrics A and A are impregnated with a synthetic resin and molded into a concavo-convex shape with a press or the like. For example, Japanese Utility Model Laid-Open No. 7-15448 A material molded by the disclosed material and molding method is used.

  The molded non-woven fabrics A and A are exposed from the trim cover portion 1 corresponding to the side portion of the trim cover constituting the side surface of the seat cushion SC, and from the outside and the lower side of the side portion of the seat cushion SC integrally with the trim cover portion 1. The finisher unit 2 is configured to cover mechanical parts such as a reclining device, a slide rail, and a lifter.

  One fastener chain 13A of the slide fastener is sewn to the terminal 12 facing the main part B of the trim cover 1 of the above trim cover part 1, and the other fastener chain 13B is sewn to the main part B as shown in FIG. ing.

  The main part B is fixed to the surface of the molded foam pad 5 by bonding or the like.

  Therefore, the pad 5 is covered by connecting the trim cover portion 1 of the molded nonwoven fabric A to the left and right of the main portion B with slide fasteners. Instead of the slide fastener, the trim cover portion 1 may be sewn and connected to the main portion B.

  The trim cover portion 1 shown in the figure is provided with bending absorbing portions 10 and 11 in the front and rear direction in two vertical stages. Therefore, the pad 5 bends due to a load, such as when seated, and the trim cover portion 1 bends following the load. The bending absorbing portions 10 and 11 absorb this bending. Accordingly, since the bending is not transmitted to the finish portion 2, the finish portion 2 is not deformed by the load.

  Although the illustrated bending absorbing portions 10 and 11 are formed of concave grooves that are recessed inward, they may be formed as protruding ridges protruding outward instead of the concave grooves.

  The trim cover portion 1 of the above molded nonwoven fabric A is sewn with hooks, insertion plates, and the like, and the hooks are fixed to the frame 6 of the seat cushion or the upper rail (not shown) of the slide rail. desirable.

  The finisher portion 2 of the molded non-woven fabric A is shaped so as to protrude outward with respect to the trim cover portion 1 in substantially the same shape as the conventional finisher.

  The molded nonwoven fabric A is preferably laminated with a decorative resin (polyester or the like) film on the surface of the molded nonwoven fabric A at the same time as molding. Since it is coated, the appearance quality is improved, and the shape retention of the molded nonwoven fabric A can be improved.

  In the drawing, reference numeral 20 denotes an accommodation recess for accommodating the operation members 3 and 4 such as the reclining device 7 for tilting the seat back SB of the finisher portion 2, and the operation member insertion ports 31 and 41 are opened. Reference numeral 21 denotes an upper projecting portion of the finisher portion 2.

  In the figure, the molded nonwoven fabrics A and A are connected to the left and right sides of the main part B, but the molded nonwoven fabric A is provided only on one side, and the other side is formed from the same material as the main part B with a trim cover. You may do it.

  The main part B is formed of a woven fabric, synthetic resin leather, leather, or the like conventionally used for this type of sheet.

Further, instead of the molded nonwoven fabric A, the trim cover portion 1, the finisher portion 2, and the bending absorbing portions 10 and 11 are made of a material having a shore hardness of about 50 or less and capable of being sewn. You may shape | mold in uneven | corrugated shape.
This material is made of, for example, a synthetic resin plate having a shape-retaining property, and synthetic leather, a film, etc., and a terminal that can be sewn with one fastener chain of a slide fastener. .

Then, the shore hardness of the trim cover portion 1 and the portion corresponding to the finisher portion 2 is changed, for example, the hardness of the trim cover portion 1 is softened with respect to the finisher portion 2, and the trim cover portion 1 is further made It may be easy to bend.
Moreover, when the said raw material is used, decoration processing etc., such as the synthetic resin material plate or synthetic leather of the outer surface side, can improve a shape retention property and can make appearance quality favorable.

  Therefore, as described above, since the side portion of the conventional trim cover and the portion corresponding to the synthetic resin finisher are integrally formed with the molded nonwoven fabric or material, the conventional finisher becomes unnecessary, and the finisher portion Since 2 is integrated with the trim cover part, there is a sense of unity in design between the seat cushion and the attached member of the seat cushion, and a seat cushion excellent in appearance quality can be provided.

A: Molded nonwoven fabric or material, 1 ... Trim cover portion of molded nonwoven fabric or material, 2 ... Finisher portion of molded nonwoven fabric or material, 10, 11 ... Deflection absorbing portion.
