The automotive industry is changing very rapidly. New components are introducing by automotive manufacturer in manner of improving passenger’s comfort and safety as well as aesthetic. Safety and comfort of occupant are very important. Recliner of automotive seat is a mechanism which is give rotation to seat back forward & rearward direction from a pivot point at the base of seat back according to the passenger’s seating comfort. Seat recliner is the most critical criteria in the design of seat structure in auto motive seat industry. The aim of this paper is to design and optimize the existing seat recliner subjected to loading. The scope of present work involves Finite Element Modeling of seat recliner assembly using HYPERMESH & ANSYS. The result in the form of stress, load and displacement are extracted using FEA result.
