Abstract

The present invention relates to a memory foam sheet for automobiles. More specifically, the structure of the seat 10 supporting the hips of the occupant when seated and the backrest 20 supporting the back of the occupant are molded into a dual structure of the memory foam 11 and the urethane foam 12 when driving for a long time. The fatigue applied to the buttocks and the lower back is solved by the body pressure distribution function that the memory foam 11 has, and it is designed to protect the body by stably absorbing the secondary shocks applied to the lower back in the event of a car collision and a collision.

Conventional automobile seat (1) is made of a polyurethane foam (12) made by foaming polyurethane, the urethane foam (12) is flexible and good elasticity to reduce the fatigue of the occupants while driving, but accumulated during long driving This also had certain limitations to relieve fatigue.

Therefore, the present invention comprises a surface of the seat 10 in direct contact with the buttocks of the occupant and the surface of the backrest 20 in contact with the back of the occupant in order to overcome the conventional problems and maximize the ride comfort of the memory foam 11, The back portion of the memory foam 11 is to provide a memory foam sheet for automobiles composed of a double of the urethane foam (12).

The present invention relates to a memory foam sheet for automobiles. More specifically, the structure of the seat supporting the buttocks of the occupant when seated and the backrest supporting the back of the occupant are molded into a dual structure of memory foam and urethane foam so that the memory foam has fatigue applied to the buttocks and the lower back when driving for a long time. It is designed to solve the body pressure dissipation function, and to protect the body by stably absorbing the secondary shock applied to the back of the car during collision and collision.

Ordinary automobile seats are made of urethane foam made of foamed polyurethane. The urethane foam has good flexibility and elasticity to reduce occupant fatigue while driving, but it also has a certain limit to relieve accumulated fatigue during long driving. There was.

In recent years, various types of devices and tools are being developed, including automobile seats, to promote comfortable and safe driving.

Therefore, the present invention was devised to overcome the limitations of the fatigue absorption rate of the conventional urethane foam sheet in order to promote a comfortable and safe operation, and the memory foam having the characteristics of low elasticity, high density and excellent fatigue absorption power with the conventional urethane foam By constructing a dual structure up and down together, to reduce the fatigue applied to the buttocks and back of the driver and occupant while driving the car, to provide a memory foam seat for a car that can be more comfortable and stable driving than conventional.

Automotive seats are generally composed of a seat 10, a back 20 and a headrest 30, as shown in FIG. The headrest 30 is configured to be mounted on the upper end of the backrest 20 through the connecting rod 31, to relieve fatigue of the head and neck portion applied to the occupant while driving. When the occupant leans back his head, the headrest 30 is supported by the back of the head and neck, and fatigue is eliminated.

In addition, as is well known, the seat 10 supports the hip of the occupant, and the backrest 20 is configured to support the back of the occupant. The seat 10, the back 20 and the headrest 30 are generally made of urethane foam 12 molded by foaming polyurethane.

Hereinafter, with reference to the accompanying drawings the technical configuration and effects of a preferred embodiment that can achieve the object of the present invention is as follows.

FIG. 2 is a cross-sectional view taken along the line AA of FIG. 1, which is a seat 10 of the vehicle, and a double structure in which the memory foam 11 and the urethane foam 12 supporting the buttocks of the occupant as shown in FIG. to be.

That is, the conventional urethane foam 12 is configured at the lower portion, and the memory foam 11 is configured at the upper portion directly in contact with the buttocks.

The memory foam 11 is a material having characteristics of low elasticity, high density, and excellent shock absorption. As the contour of the human body is shaped as it is, the contact surface is widened, so that the fatigue load applied to the buttocks is equally distributed, thereby making it feel comfortable. .

In addition, the upper and lower dual structures of the memory foam 11 and the urethane foam 12 are also applied to the backrest 20, and the fatigue load applied to the back and the waist is absorbed evenly by the memory foam 11, resulting in a comfortable ride. I can feel it.

Therefore, according to the present invention, as the buttocks and back of the occupant reach the memory foam 11 and the urethane foam 12 is formed on the back, the buttocks and the lower back contact the seat 10 and the back 20 for a long time. Even if it is, the buttocks and the lower back are not pressed by the body pressure dispersion function of the memory foam 11, which has the advantage of being able to run comfortably.

In addition, the memory foam 11 is naturally deformed along the contour of the buttocks and the lower back while the tensioned body is relaxed while twisting the tense body to the left and right, thereby providing a feeling of unification of the memory foam 11 and the whole body, thereby allowing comfortable driving. .

On the other hand, since the memory foam 11 has excellent shape restoring force, no recession occurs in the joint surface even after a long run, and as shown in FIG. 2, protrusions 13 are formed on both sides of the seat 10 to comfortably seat the buttocks. It can be done.

As described above, the automobile seat 10 and the backrest 20 according to the present invention have a memo reform 11 and a urethane foam 12 formed up and down in a double structure, and the manufacturing process thereof with reference to FIG. 3. Explain.

3 shows a molding process of the seat 10 in the configuration of the automobile seat 1, and the backrest 20 forming process is also the same.

The memory foam 11 is pre-molded in a separate mold and attached to the memory foam mounting portion 42 of the upper mold 40 of FIG. 3.

Thereafter, the urethane foam injection portion 43 of the lower mold 41 is injected with a certain amount of urethane foam 12, and then the upper mold 40 is closed. In this process, the urethane foam 12 is foamed in the sealed urethane foam injection portion 43, and is bonded to the bottom surface of the memory foam 11 in the foaming process.

After the predetermined foaming time passes, the upper mold 40 is opened to remove the seat 10, which is double-bonded, and the seat 10 of the memory foam 11 and the urethane foam 12 of the present invention are doubled up and down. This is done.

Meanwhile, another bonding method of the memory foam 11 and the urethane foam 12 is provided with the memory foam 11 and the urethane foam 12 formed in each mold and apply an adhesive or adhesive tape to the bonding surface. The memory foam 11 and the urethane foam 12 may be bonded to each other.

As a result, the technical gist of the present invention consists of a memory foam 11 comprising a surface of the seat 10 directly contacting the buttocks of the occupant and a surface of the backrest 20 to which the back of the occupant is in contact with the vehicle seat. The back portion of the foam 11 is a memory foam sheet for automobiles, which is composed of urethane foam 12.

As described above, since the fatigue applied to the hips and back of the occupant is eliminated through the present invention, it is possible to promote comfortable and stable driving, and stably absorbs the secondary shock applied to the back of the car during collision and collision. It is effective to protect the body.
