Abstract:
1. A passenger side airbag door for an instrument panel having an airbag, comprising: an instrument panel substrate defining an airbag opening; an airbag reinforcement board of a cellulosic composite material soaked by at least one of a thermoplastic plastic and a thermoplastic elastomer to allow said airbag reinforcement board to maintain a stable shape and mechanical properties and disposed continuously over said airbag opening for receiving the impact of the airbag when deployed, said airbag reinforcement board having an end portion being secured to said instrument panel substrate for allowing said airbag reinforcement board to fold along said connected end portion when the airbag is deployed and a body portion extending from said end portion and continuously over said airbag opening for receiving the impact of the airbag when deployed; a skin layer for defining an outer surface of the instrument panel and being spaced from said instrument panel substrate and said airbag reinforcement board; a foaming layer disposed between said skin layer and said instrument panel substrate and said airbag reinforcement board; a clamp plate disposed across only said end portion of said airbag reinforcement board and between said instrument panel substrate and said skin layer for sandwiching said end portion of said airbag reinforcement board between said clamp plate and said instrument panel substrate to secure said end portion of airbag reinforcement board to said instrument panel substrate; and an airbag tape disposed only on said body portion of said airbag reinforcement board and said instrument panel substrate for securing said body portion of said airbag reinforcement board to said instrument panel substrate; wherein said airbag reinforcement board folds along said clamp plate and maintains said stable shape and mechanical properties for prohibiting said airbag reinforcement board from smashing into small pieces and flying off during airbag deployment and said skin layer and foaming layer are movable with said airbag reinforcement board during airbag deployment for defining a deployment space for the airbag.
