Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION This invention relates to a resin seat component with a built-in reinforcing member, which is used, for example, in the seat back of a seat in an automobile or the like.

Moxibustion Dungeon 4 Generally, a car has a rear seat 1-cushion 1 and a rear seat 1-back 2 as shown in FIG.
As shown in FIG. 9, this seat hack 2 has a U-shaped bent portion 4a formed at the peripheral edge of a back panel 4 made of steel plate provided on the back side. Music section 4
A reinforcement 5 is joined to the inside of the back panel 4, and a pad 6 is provided to the urethane sheet serving as a cushion member on the front side of the back panel 4, and the peripheral edge 7a of the seat skin is attached to the back panel fold. The seat pad 6 is inserted into the curved portion 4a so as to cover the seat pad 6.

However, in such a seat back 2, there is a bent portion 4a on the back panel 4 just to stop the seat skin.
It takes time and effort to form the reinforcement, join the reinforcement 5, and further arrange the sea I-pad 6, and
Since the hack panel 4 is exposed on the back side of the sheet, it is necessary to perform a surface treatment on the panel 4 to prevent rust and improve its appearance, and this requires either sheet manufacturing or pigment treatment. Therefore, a seat component 10 formed by blow molding as shown in FIG. 10 was considered as a seat component 10 that has cushioning properties and can be easily manufactured.

That is, this sheet component 10 is a blow-molded resin body 11.
If it is alone, the strength is weak, so a reinforcing member 12 corresponding to the back panel 4 is required, and this reinforcing member 12 is embedded in the back side of the blow molded resin body 11 during blow molding.

Problems to be Solved by the Invention However, if such blow molding is used, it is easier to manufacture the sheet than the conventional example because it is integrally molded.
Since the reinforcing member 12 is exposed on the back side of the blow-molded resin body 11 like the hack panel 1, surface treatment is still necessary, and it is not easy to manufacture. Together.

Since the reinforcing member 12 was exposed, there was also a problem in terms of appearance quality.

Means for Solving the Problems In order to solve the problems, the present invention provides a front plate portion that is formed into a substantially box shape by flow molding and supports a seated person, and a front plate portion that is spaced apart from the front plate portion. and a back plate portion facing each other,
The seat body includes a seat body comprising a peripheral edge of the back plate part and a side plate part connecting the peripheral edge of the front plate part; A resin seat component with a built-in reinforcing member, which is equipped with a seat skin that holds a reinforcing member and covers a front plate part and a side plate part of the seat main body, the corner part of the back plate part of the seat main body A groove recessed into the seat main body is formed in the vicinity, and a recess recessed into the seat main body is formed near the corner of the seat main side side plate, and the side wall of the recess on the back plate side and the The side wall on the side plate side of the groove portion and the inner wall of the corner portion form a holding portion for holding the reinforcing member within the corner portion, and the peripheral edge of the seat skin is further inserted into the groove portion to provide reinforcement. It is characterized by being a resin sheet part with built-in parts.

According to this method, the reinforcing member is built into the seat body at the holding part and is not exposed on the surface.
It requires surface treatment such as rust prevention, and is easily manufactured by being integrally molded by blow molding.

Further, since the groove portion forming the holding portion is used for attaching the seat skin, there is no need to form a new part for attaching the seat skin, making the production of the seat 1 even easier. Moreover, by incorporating the reinforcing member into the seat body, the appearance quality is also improved.

Example Hereinafter, this invention will be explained based on examples.

1 to 6 are diagrams showing one embodiment of the present invention.

To explain the structure first, the resin sheet component of the present invention is applied to, for example, a seat back 16 of a rear seat 15 in this embodiment.

That is, this seat back 16 has a reinforcing member 18 built into a seat body 17 formed into a substantially box shape by blow molding, and a seat skin 1 in this seat body 17.
9 are installed.

The seat body 17 includes a front plate part 17a that supports the seated person, that is, serves as a backrest, a back plate part 17b that is a seat back facing the front plate part 17a, and a back plate part 17a. Peripheral portion 17c of 17b and front plate portion 1
It is formed from a side plate part 17e that connects the peripheral edge part 17d of 7a. To mold this sheet body 17, polyethylene resin, polypropylene resin, vinyl chloride resin,
All thermoplastic resins can be used, such as polystyrene resins, polycarbonate resins, acrylic resins, nylon resins, acrylic-styrene copolymer resins. This side plate portion 17e includes the second wall L7f, both vertical walls 17g and the lower Ji1
7h are formed continuously.

The back plate portion 17b has a groove 1 recessed into the seat body 17 near the corner 17i on the peripheral edge 17c side of the back plate portion 17b.
7j are formed continuously over the entire circumference.

In addition, the side plate portion 17e has two locations on the vertical wall 17g, and on the top and bottom.
Two recesses 17k are formed in each of the lower walls 17f and 17h. This recess 17 is formed near the corner 171 and is open on the front plate portion 17a side.

The gap C between the recess 17 and the groove 17j is set to be very small as shown in FIG. Then, in this recess 17,
The side wall 17+u on the back plate portion 17b side, the side wall 17n of the groove portion 17j on the side plate portion LVe side, and the inner wall of the corner portion 17i constitute a holding portion that holds the rod-shaped reinforcing member 18.

On the other hand, as shown in FIG. 5, the reinforcing member 18 is, for example, a circular pipe made of steel (a square pipe made of resin, a long plate made of steel, etc. may also be used), and a frame part 18a is formed at the corner part 17i of the seat body. At the same time, a horizontal bar 18b is provided inside this frame portion 18a. Bent portions 18c are formed at both ends of the horizontal bar 18b so as to bypass the groove portion 17j of the seat body 17. Further, in the upper and lower parts of the frame portion L8a in FIG.
Pin portions 18d and 18e protrude from the vertical wall 17g of e.

Such a reinforcing member 18 is built into the seat main body corner part 17i while being held by the holding part.On the other hand, the seat skin 19 is made of, for example, a heavy-duty material such as salt and vinyl, and is attached to the front plate part 17a of the seat main body 17. It is formed in a size and shape that covers the side plate portion 17e, and the peripheral edge portion L9a is folded and sewn with the core material 19t+ sandwiched therebetween.

This peripheral edge 19a is the groove 17 of the seat body 17.
] By being inserted and fixed inside, the seat skin 19 covers the front plate part 17a and the side plate part 17e of the seat body 17'! He finished 12th.

The lower pin portion 18e of the reinforcing member 18 protruding from the seat body 17 is fitted into the bracket 1-20 as shown in FIG. connected.

Further, the second pin portion 18d is adapted to be locked to a side wall of the vehicle body (not shown).

The sea 1-back 16 having such a configuration is integrally molded by blow molding with the reinforcing member 18 built into the seat main body 17. The reinforcing member 18, which ensures the strength and rigidity of the seat main body 17, is Since it is built into the main body 17 and does not appear on the surface, the sheet can be manufactured easily without the need for surface treatment such as rust prevention, and the appearance quality of the sheet 1 itself is also improved.

By the way, in order to incorporate the reinforcing part 18, since the inside of the seat body 17 is hollow, the problem is how to hold the reinforcing member 18. In this embodiment, the groove part 17j
A holding portion 17υ is formed in the recess 17 or the like to hold it in place. In addition, this groove 17j is connected to the sea 1 - epidermis 1.
9! By using it for mounting A, there is no need to form a new mounting part, which is advantageous in terms of manufacturing.

On the other hand, as a modification of the recess 17 of the second embodiment, the seventh
If the recess 27k is formed into a roughly V-shape when viewed from the side as shown in the figure, the recess 27k will easily deform when the front plate 17a of the seat body 17 receives force.
The cushioning property of No. 7 is better than that of the above example. Moreover, when the recess 27k is formed not only partially but over the entire circumference of the side plate portion 17e.

The cushioning properties are better.

Although the reinforcing member 18 in the above embodiment was provided continuously over the entire circumference of the corner portion 17i of the seat body 17, it is of course possible to divide the reinforcing member 18 into two parts, for example, on the upper side or the lower side. In addition, in the above embodiment, the resin seat component of the present invention is applied to the seat back 16 of the rear seat 1-15, but is not limited to this (it can be applied to a seat cushion, or it can be applied to other parts). As explained above, according to the present invention, by blow molding etc., it can be easily manufactured with cushioning properties, and Since the reinforcing member can be held within the sheet body by the holding part formed by the groove or recess, there is no need to apply anti-corrosion treatment to this reinforcing member, making manufacturing easy.
Moreover, since the reinforcing member is not visible from the outside, the appearance quality can be improved. At the same time, since the groove has two functions, one for holding the reinforcing member and the other for attaching the seat skin, there is no need to newly form a part for attaching the seat skin, which is advantageous in terms of seat manufacturing. , practical use 1: exhibits beneficial effects.
