Description

자동차용 카펫트 구조{Carpet structure for automobile}Carpet structure for automobile}

본 발명은 자동차용 카펫트 구조에 관한 것으로, 더욱 상세하게는 카펫트 하면에 PP 폼이 일정한 간격으로 삽입 발포된 PU 폼 시트를 일체로 발포성형함으로써, PU폼 시트의 딱딱함과 PP폼의 부드러움을 동시에 얻을 수 있는 자동차용 카펫트 구조에 관한 것이다.The present invention relates to a carpet structure for an automobile, and more particularly, by integrally foam molding a PU foam sheet in which a PP foam is inserted and foamed at regular intervals on a carpet, thereby obtaining both the hardness of the PU foam sheet and the softness of the PP foam at the same time. The present invention relates to a carpet structure for automobiles.

일반적으로 자동차의 실내에서는 바닥면에 소음 방지 뿐만 아니라 편의성을 추구하기 위해 카펫트를 깔고 있다.In general, the interior of the car is carpeted not only to prevent noise but also for convenience.

이러한 카펫트는 보통 신발이 직접 닿는 카펫트면과, PU 패드(felt pad)그 하면에 일체로 발포성형되어 2층 구조로 많이 제작하여 사용하고 있다.Such carpets are usually foam molded integrally with the carpet surface directly contacted by the shoe and the lower surface of the PU pad (felt pad), and are manufactured and used in a two-layer structure.

특히, 상기 PU층은 부드러움을 더해 주기 위한 것으로, 구두 등을 신고 밟게 되면 푹신한 느낌을 주게 되며, 차체로부터 전달되는 소음이나 진동을 저감시켜 주는 부수적인 기능도 가지고 있다.In particular, the PU layer is intended to add softness, and when the user puts on shoes or the like, gives a soft feeling, and has an additional function of reducing noise and vibration transmitted from the vehicle body.

그러나, 기존의 카펫트는 PU 폼 시트만을 이용하여 소음 및 진동을 흡수하기 위한 경우(두께가 약 30㎜ 이상이 되면) 푹신한 정도가 지나쳐서 오래 사용하다 보면 자주 밟히는 부분이 주저 앉게 되어 미관상 좋지 않게 되고, 또한 재질이 갖는 물성치가 떨어져서 소음 및 진동 흡수의 기능이 떨어지는 문제가 발생하게 되어 이에 대한 개선이 필요하게 되었다.However, in the case of conventional carpets using PU foam sheets only to absorb noise and vibration (when the thickness is about 30 mm or more), the softness is excessive, and when used for a long time, the stepped parts often sit down and become aesthetically unfavorable. In addition, there is a problem that the material properties of the material is dropped and the function of the sound absorption and vibration absorption is reduced, which is required to improve.

본 발명은 이러한 점을 감안하여 안출한 것으로, 카펫트의 하면에 PU 폼 시트를 일체로 발포성형하되, 이 PU 폼 시트의 상면에는 PP폼이 등간격으로 유입되어 일체로 발포성형되어 이루어진 것을 특징으로 함으로써, 카펫트를 밞으면 PU폼 시트의 부드러움과 함께 PP폼의 딱딱함을 느낄 수 있고, 이 뿐만 아니라 너무 부드럽지 않고 딱딱하지 않은 상태로 카펫트를 오랫동안 지속적으로 사용할 수 있는 자동차용 카펫트 구조를 제공하는데 그 목적이 있는 것이다.The present invention has been made in view of this point, but the PU foam sheet integrally foamed on the lower surface of the carpet, PP foam is introduced into the upper surface of the PU foam sheet at equal intervals, characterized in that the foam is formed integrally. Thus, when the carpet is woven, the softness of the PU foam sheet can be felt together with the softness of the PP foam, as well as providing a carpet structure for automobiles that can continuously use the carpet for a long time without being too soft and hard. There is a purpose.

이를 첨부도면을 참조하여 본 발명의 구성 및 작용효과를 설명하면 다음과 같다.Referring to the accompanying drawings, the configuration and effect of the present invention will be described.

첨부도면 도 2는 본 발명에 따른 카펫트 구조를 나타내는 단면도로, 도면부호 10은 카펫트를 나타낸다.2 is a cross-sectional view illustrating a carpet structure according to the present invention, and reference numeral 10 denotes a carpet.

본 발명은 상기 카펫트(10)를 제조함에 있어서, 이와 유사한 재질로 이루어져 있으면서 푹신한 느낌을 주는 재질인 PPU 시트(11)를 그 하면에 일체로 발포성형하여 이루어진 자동차용 카펫트 구조에 있어서, 상기 PU폼 시트(11)에 이보다 조금 딱딱한 느낌을 줄 수 있도록 PP폼(12)을 유입하여 일체로 사출성형하여 이루어진 것이다.In the present invention, the carpet 10, in the carpet structure for automobiles formed by integrally foaming the PPU sheet 11, which is made of a similar material and gives a soft feeling to the lower surface thereof, the PU foam It is made by injection molding integrally by injecting the PP foam 12 to give a slightly harder feeling to the sheet (11).

여기서, 상기 PU폼 시트(11)는 PP폼(12)에 비해 더 푹신한 느낌을 주게 되며, 전체적인 형상은 사각 판 상의 중앙에 등간격으로 구멍(13)이 관통 성형된 형태가 되도록 일체로 발포성형하게 된다.Here, the PU foam sheet 11 gives a more fluffy feeling than the PP foam 12, and the overall shape is integrally molded so that the hole 13 is formed through the center at equal intervals on the square plate. Done.

특히, 상기 구멍(13)은 꼭지점 부위가 절개된 역원뿔 형상으로 성형하게 되는데, 이는 카펫트(10)를 밟게 되면 넓은 범위에 걸쳐 상기 구멍(13)에 발포성형되는 PP폼(12)에 의해 지지될 수 있도록 하기 위함이다.In particular, the hole 13 is formed into an inverted cone shape in which the vertex is cut off, which is supported by the PP foam 12 which is foamed into the hole 13 over a wide range when the carpet 10 is stepped on. To make it possible.

즉, 상기 PU폼(12)은 PP폼(11)보다 더 딱딱한 재질로 PU 폼 시트(11)의 윗면에서 차지하는 면적을 넓게 함으로써, 카펫트(10)를 밟게 되면 푹신한 느낌과 함께 딱딱한 느낌을 가질 수 있도록 한 것이다.That is, the PU foam 12 is made of a harder material than the PP foam 11, thereby widening the area occupied by the upper surface of the PU foam sheet 11, and when the carpet 10 is stepped on, the PU foam 12 can have a hard feeling with a fluffy feeling. It would be.

따라서, 상기 PP 폼 시트(11)는 원래 가지고 있는 푹신한 느낌과 함께 이보다 딱딱한 느낌을 주는 PU폼(12)이 일체로 발포성형되어, 발로 밞게 되면 이 두가지 느낌을 동시에 가질 수 있게 되는 것이다.Accordingly, the PP foam sheet 11 is foamed integrally with the PU foam 12 which gives a softer feeling as well as the original softness, and when the foot is squeezed, it is possible to have these two feelings simultaneously.

이상에서 본 바와 같이 본 발명은 카펫트의 하면에 일체로 성형되는 PU 폼 시트의 윗면에 이보다 딱딱한 느낌을 주는 PP폼이 등간격으로 배치되도록 발포성형함으로써, 푹신한 느낌과 함게 조금 딱딱한 느낌을 동시에 느낄 수 있으며, 또한 오랜 사용에도 푹신한 PU폼 시트가 원래의 물성 특성이 없어지는 것을 방지할 수 있게 되어 수명의 연장으로 상품성을 높일 수 있는 효과가 있는 것이다.As described above, the present invention is foamed to be arranged at equal intervals on the upper surface of the PU foam sheet integrally molded on the lower surface of the carpet, by foam molding, so that you can feel a little hard at the same time with a fluffy feeling In addition, the PU foam sheet fluffy even after long use is able to prevent the loss of the original physical properties has the effect of increasing the product life by extending the life.
