Publication number: 20020079678Abstract: An air bag device having a switch adapted to be operated when a breakable cover member covering an air bag module mounted in the steering wheel is pushed. Particularly, H-shaped tear lines, including grooves of a V-shape in section, are defined in an inner surface of the cover member. The tear lines are broken by a pressure resulting from the expansion of the air bag to open a lid defined in the cover member. A pair of ridges are integrally formed on the cover member astride a central one of the tear lines. The rigidity of the rear cover member is enhanced by the ridges, whereby the deformation of the cover member is prevented. Thus, the cover member can be slid smoothly to ensure the reliable operation of the switch.Type: ApplicationFiled: October 9, 2001Publication date: June 27, 2002Applicant: Honda Giken Kogyo Kabushiki KaishaInventors: Takeshi Kai, Toshiya Sakai, Hiroyuki Saitoh, Masahiro Sato
