Patent number: 7703799Abstract: In an airbag module cover, at least one pair of tear lines is provided on a double-wall portion (an inner side wall and an outer side wall). The tear line provided on the inner side wall is formed as a slit. The tear line provided on the outer side wall is formed as a groove. Therefore, strength of the double-wall portion is reduced to tear the tear lines unfailingly and torn module cover can be opened unfailingly as a deployment door by an inflating airbag.Type: GrantFiled: July 25, 2007Date of Patent: April 27, 2010Assignee: Nihon Plast Co., Ltd.Inventor: Mamoru Takagi
