Description

  The present invention relates to a seat back of an automobile seat, and more particularly to a surface structure of the seat back.

  Conventional seat backs for automobile seats include a foam pad applied to a frame and covered with a skin that is sewn into a bag shape.

  In addition, there is also one in which the pad is integrally formed on the skin and the surface is given a concavo-convex shape (for example, JP-A-2-307494).

  Furthermore, in order to improve the assemblability of the skin, the one that divides the skin on the back side of the seat back from the skin on the front side and connects them together with a slide fastener (for example, Japanese Patent Application Laid-Open No. 2005-262628) It is disclosed.

JP-A-2-307494 JP 2005-262628 A

  The above skin is made of a material that is difficult to form in a concavo-convex shape such as woven fabric, synthetic resin leather, leather, etc., so that the surface shape is uneven by molding or adhering to the foam pad integrally. It is trying to become.

  On the other hand, there is one using a nonwoven fabric (felt) on the back side of the seat back, for example, which has the advantage that it can be sewn with a sewing machine to a skin made of woven fabric on the front side of the seat back, and is widely practiced.

  However, since the whole using this non-woven fabric is flat, a recess cannot be formed on the back side of the seat back so as to ensure a sufficient foot space for the rear seat.

 In order to solve such a problem, there is one in which a resin plate formed by injection molding with a synthetic resin such as polypropylene and having a recess for the foot space is provided on the back side of the seat back.

  Since this is a resin plate, not only is it difficult to sew the outer skin, but it must be locked to the frame side of the seat back, requiring man-hours for its installation work, and after installation, When the knee or foot hits, the resin plate comes into contact with the spring stretched around the frame in the seat back, and there is a drawback that abnormal noise is generated.

  Therefore, the present invention aims to solve the above-mentioned problems of the conventional product.

  In order to achieve the above object, the automotive seat back according to claim 1 synthesizes either or either the front skin constituting the front side of the seat back and the back skin constituting the back side of the seat back. It is characterized by being formed of a molded nonwoven fabric formed by impregnating a resin and molding it into a concavo-convex shape.

  The invention of claim 2 is configured by laminating a resin film for decoration on the surface of the molded nonwoven fabric.

  The invention of claim 3 has a configuration in which a recessed portion for a foot space for a rear seat is provided in the molded nonwoven fabric.

  The invention according to claim 4 is characterized in that the rear skin comprises the upper part of the front skin and the upper part of the rear skin, and the molded nonwoven fabric connected to the upper part of the rear skin and the left and right sides of the front skin. The non-woven fabric is formed in an inverted U-shape upward, and its upper end is formed in a substantially horizontal shape toward the inside, and the ends of this non-woven fabric are formed at both the upper end of the rear epidermis and the left and right sides of the front epidermis. It is the structure formed by integrally connecting with the engaging means which mutually engage.

  In the invention of claim 5, the front skin constituting the front side of the seat back and / or the rear skin constituting the back side of the seat back have at least a Shore hardness of about 50 or less. However, there is a configuration in which a material that can be sewn is formed into a concavo-convex shape, and for example, synthetic leather is attached to a synthetic resin material.

  According to the first aspect of the present invention, since the molded nonwoven fabric can be formed into a concavo-convex shape, the foam pad is integrally foamed on the skin, or the pad is bonded to the skin, as in the conventional product, It is not necessary to give unevenness to the skin. Therefore, for example, an uneven shape can be formed on the back side of the seat back without providing a pad on the back side.

  The invention of claim 2 is configured such that the material is a molded nonwoven fabric formed by impregnating a synthetic resin into a concavo-convex shape, or a member in which synthetic leather is bonded to a synthetic resin material. Since the material can be formed into a concavo-convex shape, it is not necessary to impart a concavo-convex shape to the skin by integrally foaming a foam pad on the skin or adhering the pad to the skin as in the conventional product. Therefore, for example, an uneven shape can be formed on the back side of the seat back without providing a pad on the back side.

  Moreover, when shape | molding and demolding the said shaping | molding nonwoven fabric, since a shaping | molding nonwoven fabric has a softness | flexibility, it can shape | mold to a desired complicated uneven | corrugated shape.

  In addition, since the molded nonwoven fabric can be stitched to other skin members, a seat back excellent in design can be provided.

  According to the second aspect of the present invention, since the molded nonwoven fabric is covered with the decorative resin film, a seat back excellent in design can be provided.

  According to the third aspect of the present invention, even if the molded nonwoven fabric is soft and comes into contact with the spring material in the seat back, no abnormal noise is generated. Therefore, the molded non-woven fabric can be brought close to the spring member in the seat back, the foot space can be formed in an enlarged shape with respect to the conventional product, and the usability of the foot space can be improved.

  According to the invention of claim 4, since the molded nonwoven fabric is formed independently with respect to the upper part of the rear skin, the left and right sides of the front skin, it is easy to assemble the front skin, etc. In addition, it is easy to sew engagement means to the ends of the molded non-woven fabric and both the left and right both sides of the upper part of the rear skin and the front skin, and the connection by the engagement means to the front skin of the molded non-woven fabric is smooth. Can be done.

  In particular, when a slide fastener is used as an engagement means between the molded non-woven fabric and the upper part of the rear skin, it is easy to sew the molded non-woven fabric of the slide fastener and the upper part of the rear skin, and the operability of the slider of the slide fastener is improved. Well, the connection by the slide fastener can be performed smoothly.

According to the invention of claim 5, the front epidermis constituting the front side of the seat back and the rear epidermis constituting the back back side of the seat back have a Shore hardness of about 50 or less. Since it is formed in a concavo-convex shape from a material that can be stitched, the front epidermis and the rear epidermis can be connected by stitching a slide fastener etc. to the terminal, or both terminals can be sewn together with a sewing machine . Furthermore, by making the entire material harder to a shore hardness of about 50 or less, it is possible to easily ensure deflection in the foot space for the rear seats, and to give the back seats a different texture. You can provide what you don't give.
Moreover, since it has a softness | flexibility like the said shaping | molding nonwoven fabric, the effect similar to the said shaping | molding nonwoven fabric is acquired, such as being able to shape | mold into a desired complicated uneven | corrugated shape.

The perspective view of the shaping | molding nonwoven fabric used for this invention. FIG. 5 is a sectional view taken along line ZZ in FIG. 4. The perspective view of another Example.

  1 to 5 show a first embodiment of the present invention, in which 1 is a molded nonwoven fabric, 2 is a front skin comprising a conventional skin member and constituting the front side of the seat back SB, 3 is a foam pad, Reference numeral 4 denotes a frame, and 5 denotes a spring stretched around the frame 4.

  The front skin 2 shown in the figure is composed of a body 21 that is located on the front surface of the seat back SB and a town 20 that is integrated with the body 21 and is located on the front side of the side surface of the seat back SB. It is integrally formed. The upper part 22 and the upper part of the town 20 are integrally stitched with a rear skin upper part 22 with a pad 30 located on the back side of the seat back SB.

  The above front skin 2 and the like are all formed of woven fabric, resin leather, leather or the like used in conventional seat backs.

    The above molded non-woven fabric is a non-woven fabric that is press-molded by impregnating a polyester fiber with an SB resin and heated, as disclosed in, for example, Japanese Utility Model Publication No. 7-15448. A recess 10 for a person's foot space is formed.

  And, it is preferable to laminate a decorative resin (polyester or the like) film simultaneously with the molding of the molded nonwoven fabric, and by laminating in this way, the outer surface of the molded nonwoven fabric is covered with the resin film, so that the appearance quality is improved. In addition, the shape retention of the molded nonwoven fabric can be improved.

  As shown in the drawing, the molded nonwoven fabric 1 is formed in an inverted U shape upward, and constitutes the lower back portion of the seat back SB and the outer surfaces of the rear half portions of the left and right side surfaces.

  In the figure, 10A is the bottom of the concave portion 10, 11 is the central portion of the molded nonwoven fabric 1, 12, 12 are the same side portions, 13 is the upper portion, 14 is the bent portion, and 15 and 15 are the ends of the side portions 12 and 12, respectively. .

  The upper part 13 of the above-mentioned molded nonwoven fabric 1 is formed in a substantially right angle with respect to the central part 11 as shown in FIG. Therefore, the molded non-woven fabric 1 is bent inward in a substantially horizontal direction in an attached state, and one fastener chain 16A engaging with each other is sewn with a sewing machine. The one fastener chain 16A is provided along the terminals 15 and 15 of the side portions 12 and 12.

  Accordingly, one slide chain 16A is provided behind one terminal 15, the upper 13 terminal, and the other terminal 15, and the upper 13 terminal is substantially flat. One fastener chain 16 </ b> A is easily sewn from the end toward the end of the upper portion 13.

  The other fastener chain 16B that engages with the one fastener chain 16A is stitched to the left and right gussets 20 of the front skin 2 and the end of the upper upper skin 22 respectively, and both fastener chains 16A and 16B are engaged with a slider. By doing so, the molded nonwoven fabric 1 is integrally connected to the front skin 2 or the like to form the seat back SB.

  When the fastener chains 16A and 16B are engaged with each other by the above slider, the upper part 13 of the molded nonwoven fabric 1 to which the fastener chain 16A is sewn is substantially horizontal, so that the upper part 13 extends from the terminal 15 on one side 12 side. The molded nonwoven fabric 1 can be accurately and easily connected to the terminal 15 of the other side portion 12 so that the slider can easily move.

  Therefore, when the back side of the seat back SB is formed with the molded nonwoven fabric 1 as described above, since the molded nonwoven fabric 1 is soft, no abnormal noise is generated even if the inside of the recess 10 contacts the spring 5.

  Therefore, the depth of the recess 10 can be increased so that the recess 10 can be brought close to the spring 5, thereby increasing the foot space for the rear seat.

  The bent portion 14 of the molded nonwoven fabric 1 is fixed to the bottom portion of the seat cushion SC so that the lower end portion of the seat back SB is not exposed when the seat back SB is moved forward.

  Further, the lower end portions 12A and 12A of the left and right side portions 12 of the molded nonwoven fabric 1 are configured to be bent inward so as to reliably cover a reclining device (not shown).

  In the second embodiment shown in FIG. 6, the skin of the seat back is divided into two parts, the front skin 2 and the rear skin, and both are integrally connected by the slide fasteners 16A and 16B. The entire rear skin is formed of a molded nonwoven fabric 1 ′.

  The concave portion 10 is formed in the molded nonwoven fabric 1 ′, and the molded nonwoven fabric 1 ′ is also molded from the same material as the molded nonwoven fabric 1. In the figure, 12 'and 12' are side portions of the molded non-woven fabric 1 'and form the rear half of the side surface of the seat back SB.

  Instead of the molded non-woven fabric 1, it may be formed in a concavo-convex shape from a material that has a Shore hardness of about 50 or less and can be stitched. This material has shape retention and can be formed into an uneven shape by a press or the like, and at least the terminal can be sewn, for example, a synthetic resin material bonded with synthetic leather. The front and rear epidermis can be connected to each other by sewing a slide fastener with a sewing machine, and the terminals of both can be sewn together with the sewing machine.

  By making the hardness of the entire material a shore hardness of about 50 or less, it is possible to easily secure the deflection in the foot space for the rear seats and to give the back seats a different texture. Can offer things.

  When using the above synthetic resin material with synthetic leather bonded to the above-mentioned material, it is preferable to decorate the outer surface of one or both of the synthetic resin material and the synthetic leather.

  Therefore, even if the above materials are used in place of the molded nonwoven fabric, the same effects as the molded nonwoven fabric can be obtained. It is done.
