Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a seat cushion for a vehicle, which is mainly used as a seat cushion for an automobile.

(Prior art) Seat cushion pads are molded and integrated on both sides of the seat with approximately triangular hollows on the back side and the top slightly protruding from the seat surface. A vehicle seat cushion that is fitted and covered with a seat cover is
These vehicle seat cushions are widely known for being comfortable to sit on and can be mass-produced at low cost, but the back side of the seat has a generally triangular cross section and deforms due to repeated getting on and off. However, it is not possible to maintain a firm appearance for a long period of time, and especially when the seat spring's fitting mouth part and upper frame line are housed in the hollow part, the seat side parts may wear out, and the durability may deteriorate. It was lacking in sex.

(Problem to be solved by the invention) In addition, in a seat cushion pad in which the seat side part is integrally molded with the top slightly protruding from the seat seating surface, an insert member is attached to the seat cushion pad in order to maintain the shape of the seat side part. The idea of integrally molding the insert member inside the side part can be seen in Japanese Utility Model Application Publications No. 58-121254 and Japanese Utility Model Application No. 60-180554, but integrating the molding of the insert member complicates the molding process and is difficult to achieve in mass production. Not only are there problems, but application to the side portion of a relatively thin sheet with a generally triangular cross section poses many technical problems, resulting in high costs.

(Means for Solving the Problems) The present invention solves the above-mentioned problems and improves the shape retention of the seat side parts and the inner strength of the seat cushion without impairing the features of the seat cushion for this type of vehicle. This eliminates the wear and tear that occurs when the spring comes into contact with the mouth part and the upper frame line.The seat side part has a hollow part with a roughly triangular cross section on the back side on both sides of the seat seat part, and the top part of the seat part is attached to the seat surface. A seat cushion pad which is integrally molded with a slight protrusion is fitted onto the seat spring with the seat spring's fitment mouth part and upper frame line housed in the hollow part, and then covered with a seat cover. The seat cushion for a vehicle is characterized in that an auxiliary pad material having a substantially triangular cross section is fitted and held in the hollow portion, and is attached to the inner surface of the seat side portion 4 to reinforce the seat side portion. be.

(Function) This type of vehicle seat cushion is installed inside the vehicle body like conventional ones of this type, and has a body holding function on the side of the seat with the top protruding from the seat surface on both sides, a seat spring and The cushioning properties of the seat cushion pad fitted into this cushion provide a comfortable feeling of use, and
Even if the seat side part is thin, the auxiliary pad material that fits and holds in the cavity reinforces the seat side part from the inside and maintains the shape of the seat side itself, and the fish mouth part has a seat spring on the inside. The upper frame line prevents wear and tear, ensuring long-term durability.

(Embodiments) Next, the present invention will be described in detail with reference to illustrated embodiments.

1 has seat side parts 4 integrally molded on both sides of a seat seat part 2, each having a hollow part 3 having a substantially triangular cross section on the back surface, and a similar seat rear part 5 also integrally molded on the rear side of the seat seat part 2. The seat cushion pad is made of polyurethane foam, and the tops of the seat side parts 4, 4 and the seat rear part 5 are both slightly protruded from the seat surface of the seat seat part 2 and are relatively shallow. It has a bucket shape. Reference numeral 6 denotes a seat spring stretched between the frames, and the seat cushion pad 1 is fitted and supported by the seat spring 6, and has the above-described approximately triangular cross section in which the seat mouth portion and upper frame line are accommodated. An auxiliary pad material 7 made of polyurethane foam and having a substantially triangular cross section is fitted and held in the hollow portion 3 so as to line and reinforce the inner surface of the seat side portion 4. In addition, this auxiliary pad material 7
When the seat cushion pad 1 is molded, it can be bent and attached to the inner surface of the seat side parts 4, 4 by bending it continuously at the hem end of the seat side parts 4, 4. Of course, it may be separately molded, and its foaming degree and material may be the same as or different from the seat cushion pad 1. Further, numeral 8 in the figure is a seat cover on which the seat cushion pad 1 is covered.

When this type of seat cushion is installed in the vehicle body, the seat cushion pad 1 is placed on both sides of the seat portion 2 with the top slightly raised above the seat surface. The seat side parts 4 are integrally molded, and the overall design is shallow and bucket-shaped, which is excellent in terms of design.The seat side parts 4 also have a body-retaining function and a seat spring. 6 and the cushioning properties of the seat cushion pad 1 itself, providing a comfortable feeling of use, which is the same as with conventional seat cushions for this type of vehicle. A seat side portion 4 is provided in the hollow portion 3 having a substantially triangular cross section formed on both sides.
The auxiliary pad material 7, which has a substantially triangular cross section, is fitted and held so that the inner surface of the seat spring 6 is lined and reinforced. Even if the friction of It is possible to maintain a firm appearance for a long period of time without deforming the seat side portion 4 due to repeated bending.

(Effects of the invention) As is clear from the above description, the present invention can replace the conventional seat shoes for this type of vehicle by simply fitting and holding an auxiliary pad material having a triangular cross section into the cavity so as to line the inner surface of the side of the seat. The shape retention of the seat side parts is increased without compromising the features of the seat, and the seat side parts are reinforced from the inside without being worn away by the seat mouth part of the seat spring and the upper frame line, making it durable for a long time. In addition, the auxiliary pad material, which has a substantially triangular cross section, is simply fitted and held in the cavity along the inner surface of the seat side, and does not require a complicated process unlike the case where the insert member is integrally molded. Moreover, it has many advantages, such as being able to be applied even if the side portions of the sheet are thin.

Therefore, the present invention solves the problems of conventional seat cushions for this type of vehicle, and has the advantage of being simple in structure and easy to mass-produce, so it can be provided at low cost, and has extremely high practical value. It is.
