Description

Comfort car seat foam

technical field

The utility model relates to the technical field of automobile seat cushions, in particular to a comfortable automobile seat foam.

Background technique

At present, the vehicle seat is mainly composed of a support frame, foam and a mask. The foam is mainly used to make the occupant sit in the safest position in the vehicle seat, and at the same time to improve the comfort of the seat and reduce the impact of collision. To protect people and appliances from damage, the seat foam of automobiles and other vehicles is the most used. Generally speaking, the seat cushion should make people sit comfortably and reduce fatigue. Generally speaking, the softer the better, but too soft will make people feel sticky in the seat, making it inconvenient to move the body and change posture, while too hard will improve comfort. Reduced, so each production factory is adjusting its softness to improve, in order to obtain an optimal effect. At present, all domestic manufacturers involved in foam cushions use cushions with the same density and the same rebound rate, but this kind of foam cannot solve the above problems well.

Utility model content

In order to solve the above technical problems, the utility model provides a comfortable car seat foam.

The technical scheme is as follows: a comfortable car seat foam, its key lies in: comprising a hard layer positioned at the lower layer and a soft layer positioned at the upper layer, a fabric layer is arranged between the hard layer and the soft layer, the The hard layer and the soft layer are closely connected to each other through the fabric layer, and the area of the fabric layer is greater than or equal to the contact surface of the hard layer and the soft layer. Using the above technical solution, the foam adopts two kinds of materials with different hardness. The hard layer mainly plays the role of supporting load-bearing, and the soft layer is directly used as the contact layer with the occupants. The touch is softer and more comfortable, and the riding feeling is better. In an accident, it can protect the occupant to a certain extent and prevent the occupant from being injured.

As a preference: the above-mentioned soft layer is staggeredly distributed with deformation-expandable communication grooves, and the deformation-expandable communication groove divides the upper part of the soft layer into a plurality of supporting blocks. With this design, the deformation amount generated after the soft layer is deformed by force can be absorbed by the deformation expansion channel, and the pressure distribution is more uniform.

Air holes are respectively provided in the hard layer and the soft layer, and the air holes in the hard layer communicate with the air holes in the soft layer. Adopting this scheme, the ventilation holes play the role of ventilation and ventilation, so as to prevent the occupants from feeling stuffy when riding.

The middle and rear parts of the soft layer are respectively provided with the support blocks, and each of the support blocks is respectively provided with the air holes. With this design, the middle and rear parts of the seat cushion bear most of the occupant's pressure, and the support block can better absorb the occupant's pressure.

The thickness of the hard layer is greater than 20mm, and the thickness of the soft layer is greater than 30mm. The thickness used is the minimum thickness that the occupant feels more comfortable.

The fabric layer is made of non-woven fabric.

The front part to the middle part of the soft layer gradually slopes down to form a leg support part, and the rear part of the soft layer protrudes upwards to form a buttock support part. The leg support part of this solution lifts the occupant's legs upward slightly to relieve the discomfort of sitting for a long time.

The thickness of the front portion of the hard layer is smaller than that of the rear portion. With this design, the rear part is the main load-bearing part, and the thickness of the hard layer here is slightly thicker, which is conducive to improving the strength of the foam.

The air holes are gradually inclined towards the rear of the soft layer from bottom to top. When the design is adopted, the vent hole is not easy to be squeezed and closed by the deformed soft layer or hard layer when the occupant rides.

The grammage of the above non-woven fabric is 30-50 g/m ² .

Beneficial effect: the beneficial effect of adopting the utility model is that the foam adopts two kinds of materials with different hardness, the hard layer mainly plays the role of supporting load-bearing, and the soft layer is directly used as the contact layer with the occupants, the touch feeling is softer and more comfortable, and the riding feeling is better , and in the process of riding, especially in an accident, it can protect the occupant to a certain extent and prevent the occupant from being injured.

detailed description

Below in conjunction with embodiment and accompanying drawing, the utility model is further described.

As shown in Fig. 1 and Fig. 2, a kind of comfortable car seat foam comprises the hard layer 1 that is positioned at the lower layer and the soft layer 2 that is positioned at the upper layer, is provided with between the hard layer 1 and the soft layer 2 The fabric layer 3, the hard layer 1 and the soft layer 2 are closely connected to each other through the fabric layer 3, and the area of the fabric layer 3 is greater than or equal to the contact surface of the hard layer 1 and the soft layer 2.

The soft layer 2 is staggered with deformable telescopic grooves 4 along its length and width directions, and the deformable telescopic grooves 4 divide the upper part of the soft layer 2 into a plurality of supporting blocks 6, and the hard layer 1 and the soft layer 2 are respectively provided with air holes 5, the air holes 5 in the hard layer 1 communicate with the air holes 5 in the soft layer 2, the middle and rear of the soft layer 2 Each of the support blocks 6 is respectively provided with the air holes 5 , and the air holes 5 are gradually inclined toward the rear of the soft layer 2 from bottom to top.

The front part to the middle part of the soft layer 2 gradually slopes down to form a leg support part, and the rear part of the soft layer 2 protrudes upwards to form a buttock support part, and the thickness of the buttock support part is greater than that of the leg support The thickness of the front part of the hard layer 1 is less than the thickness of the rear part, the thickness of the hard layer 1 is greater than 20mm, the thickness of the soft layer 2 is greater than 30mm, and the material of the fabric layer 3 is Non-woven fabric, the non-woven fabric has a grammage of 30-50 g/m ² , preferably 40 g/m ² .

Finally, it should be noted that the above description is only a preferred embodiment of the utility model, and under the inspiration of the utility model, those skilled in the art can make many A similar representation, such transformations all fall within the protection scope of the present utility model.
