Abstract

The utility model discloses a seat foam assembly, comprising a foam assembly body (1). The foam assembly body (1) comprises a concave seat cushion in the middle, and bumps at a left end part and a right end part; and a regenerative foam block (2) is arranged inside each of the left end part and the right end part of the foam assembly body (1). With the adoption of the technical scheme, the seat foam assembly has the advantages of simple machining process and low manufacturing cost, meets the requirements of having a soft middle part and two hard side parts, and is comfortable and durable. Furthermore, regenerative foam is pre-embedded in the seat foam, so that the waste foam can be treated for a useful purpose, and the purpose of reusing the waste is achieved. The seat foam assembly is very beneficial because the waste foam is non-degradable and can be circularly used.

Description

The seat foam assembly

Technical field

The utility model relates to a kind of foam assembly of automotive seat, particularly a kind of foam assembly of seat cushion of automobile rear seat.

Background technology

Automotive seat are made up of seat cushion and backrest, and its function is respectively passenger's buttocks and back to be provided support.The two is formed by skeleton, foam assembly and face cover.Skeleton is the basis of supporting, and the face cover then makes seat have good surface appearance and texture, and the foam assembly makes and takes advantage of seat comfortable and have certain modeling function.So it is in order to let seat take advantage of seat comfortable, softer on the one hand with the foam requirement of human body back, buttocks contact site; But requiring simultaneously the health outside that certain support is arranged again is coated sensation, and seat will have good moulding and other requirements, and this just requires the both sides of seat foam partly to want hard relatively.The orthodox method that realizes this function is dual density even multi-density foam, and promptly seat foam is made different density in different at different position and different, to reach the different effect of different parts soft or hard.But this makes the production technology of seat foam assembly become complicated undoubtedly, makes productive costs high, and foam is generally nondegradable product, being processed in order to let the problem of people's headache of waste and old foam.

The utility model content

In order to solve the problems of the technologies described above, the present invention provides a kind of productive costs low, and processing technology is simple, two hardness seat foam assemblies of environmental protection.

To achieve these goals; The technical scheme of the utility model is following: a kind of seat foam assembly; Comprise foam assembly body (1); Said foam assembly body (1) comprises the right ends portion of umbilicate cushion portion and convexity, and the inside of the right ends portion of said foam assembly body (1) is provided with the regenerated foam piece of being processed by the primary foam beads of scrapping (2).

Adopting technique scheme, regenerated foam is to break into the foam that granule and foam raw material are processed through second time of foaming by a certain percentage by the primary foam of scrapping.The primary relatively foam of regenerated foam is general hard.When making the seat foam assembly, establish the regenerated foam piece in the both ends of foam assembly, thereby make the hardness at both ends greater than the hardness of middle cushion; On the one hand: processing technology is simple, and low cost of manufacture is soft in the middle of having satisfied; The requirement that both sides are hard, both comfortable, durable again.Another fermentation, pre-buried regenerated foam in seat foam for the processing of scrapping foam provides a useful place to go, reaches the waste and old purpose of utilizing again.For the non-degradable and the cycling and reutilization characteristic of waste foam, this is highly profitable beyond doubt.

In technique scheme: said regenerated foam piece (2) is positioned at the middle part of the right ends portion of foam assembly body (1).

In technique scheme: the volume of said regenerated foam piece (2) be foam assembly body (1) right ends portion volume 2/3rds to 4/5ths.Make the hardness of right ends portion be guaranteed like this.

Beneficial effect: the utility model is reasonable in design, simple in structure, enforcement is easy, low cost of manufacture, and processing technology is simple, and is not only comfortable but also durable.

The specific embodiment

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

Embodiment 1; Shown in Fig. 1-3; The seat foam assembly of the utility model mainly is made up of foam assembly body 1 and regenerated foam piece 2, and said foam assembly body 1 comprises the right ends portion of umbilicate cushion portion and convexity, and this is a prior art; Do not do at this and to give unnecessary details; The inside of the right ends portion of said foam assembly body 1 is provided with regenerated foam piece 2 (regenerated foam is to break into the foam that granule and foam raw material are processed through second time of foaming by a certain percentage by the primary foam of scrapping, and this is a prior art, also its preparation technology is not further specified at this); Said regenerated foam piece 2 is positioned at the middle part of the right ends portion of foam assembly body 1, and the volume of said regenerated foam piece 2 be foam assembly body 1 right ends portion volume 2/3rds to 4/5ths.

Claims

1. seat foam assembly; Comprise foam assembly body (1); Said foam assembly body (1) comprises the right ends portion of umbilicate cushion portion and convexity, and it is characterized in that: the inside of the right ends portion of said foam assembly body (1) is provided with regenerated foam piece (2).

2. according to the said seat foam assembly of claim 1, it is characterized in that: said regenerated foam piece (2) is positioned at the middle part of the right ends portion of foam assembly body (1).

3. according to the said seat foam assembly of claim 1, it is characterized in that: the volume of said regenerated foam piece (2) be foam assembly body (1) right ends portion volume 2/3rds to 4/5ths.
