Description

차량 도어의 도어트림에 장착되는 핸들 제조방법{METHOD FOR MANUFACTURING HANDLE MOUNTED DOOR TRIM}Method for manufacturing a handle mounted on the door trim of a vehicle door

본 발명은 차량 도어의 도어트림에 장착되는 핸들 제조방법에 관한 것이다.The present invention relates to a method for manufacturing a handle mounted on a door trim of a vehicle door.

일반적으로 차량 실내에 설치되는 각종 장비는 탑승자의 접촉에 의해 전달되거나 공기 등을 통하여 외부로부터 유입되는 세균에 쉽게 노출되어 있다.In general, various types of equipment installed in the interior of a vehicle are easily exposed to germs that are transmitted through contact with passengers or introduced from the outside through air or the like.

예컨대, 탑승자의 승하차시 탑승자가 조작하는 도어 인사이드 핸들, 그립 핸들 등은 세균이 번식하기 쉽다.For example, a door inside handle, a grip handle, etc. operated by an occupant when the occupant gets on or off is easy to breed bacteria.

이를 위하여, 종래에는 별도의 살균제 등을 분사하거나 도포하여 세균을 제거한다. 그러나 살균제로 살균하는 것은 시간이 많이 소요되기 때문에 번거로울 수 밖에 없다. 또한 그 효과는 시간이 지나면 소멸되기 때문에 반복해서 살균작업을 해야 하는 문제점이 있다.For this purpose, conventionally, a separate sterilizing agent or the like is sprayed or applied to remove bacteria. However, sterilization with a disinfectant is time-consuming and therefore cumbersome. In addition, since the effect disappears over time, there is a problem in that the sterilization operation must be repeated.
