In automotive industry, vehicle seat has been came first to mind at beginning of components that is encounter directly with customer. The customers have many expectations in terms of aesthetics, functionality and comfort from the seats of vehicle. When considering comfort in car seats, backrest, cushion, headrest foam and upholstery are the place of at the top of the list. The seat upholstery in vehicle has a composite structure by including fabric, lamination foam and backing scrim. This composite structure is combined with the foam by using techniques such as traditional method or in-situ technology. In traditional method, the upholstery is trimmed on the product’s foam. In in-situ technology, PU is injected into ready-placed upholstery. The advantage of in-stu technology is to make a perfect trimming for curved foam designs. Especially in headrest, it is preferred concave shapes for distance that effects on comfort and also safety between the driver's head and the seat headrest. In in-situ process, an overflow failure may occure from the upholstery surface of injected foam including polyurethane (PU) with high pressure during process. Overflow failure is not required by main automobile producers for aesthetical aspect and quality point of view. In this study, it is evaluated the effect of lamination foam and fabric in composite structure on overflow failure. In evaluation of overflow behaviour of PU injected foam, fabric types and lamination foam types were tested regarding weight measurement, peeling strength and air permeability. Final products as headrest were obseved by 40x microscop to evaluate the overflow failure.
Günümüzde fikri mülkiyet hakları; sektörde bilgi odaklı çalışmaların ve bilgi ekonomisinin artışı sonucunda firmalar için bir farklılaşma adımı, rakiplerin önüne geçmek ve küresel piyasa koşullarında hayatta kalmak için olmazsa olmaz bir duruma gelmiştir. Birçok sektörde olduğu gibi, otomotiv sektöründe de sahip olunan maddi varlıkların yanı sıra maddi olmayan varlıklar giderek önem kazanmıştır. Maddi olmayan varlıkların başında ise fikri mülkiyet hakları; özellikle patent gündeme gelmektedir. Süreçlerini olumlu tamamlayan buluşlar için patent başvuruları yapılmakta ve belirli bir patent portföyü oluşmaktadır. Böylelikle tescil sayısının artması ve nitelikli patentler ile birlikte patentlerden kazanılacak faydalarda artış olması ön görülmektedir.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
