Abstract
An airbag module of a type that only a module cover is moved to actuate a horn switch and at least one switch unit is arranged between spoke-fitting portions, wherein a portion around either of spoke-fitting portions on both sides of the switch unit can be prevented from being excessively deformed, thereby providing an improved horn switch operational feeling. Hooks are loosely fitted in holes formed in leg portions of a module cover for a predetermined space, whereby the module cover can move vertically. As a portion around lower left and lower right spoke-fitting portions is pressed, a switch unit arranged therebetween is actuated. The spoke-fitting portions are provided with stoppers projecting therefrom. The stoppers are disposed such that their ends can come in contact with extension pieces of the horn switch supporting member.
Claims10
An airbag module comprising:
- a folded airbag;
- a retainer to which the airbag is secured,
- a module cover including a plurality of spoke-fitting portions for covering the airbag;
- and
- a horn switch disposed between two of the spoke-fitting portions under a portion of the module cover not including one of the spoke fitting portions, the switch being actuated by pressing the module cover downward;
- and
- a plurality of stoppers for preventing the spoke-fitting portions interposing the switch therebetween from being moved downward in excess of a predetermined distance.
An airbag module comprising:
- a retainer for an airbag, the retainer including a hook;
- a module cover with an opening for receiving the hook to connect together the retainer and module cover;
- a horn switch;
- and
- a stopper for preventing the module cover from being moved toward the retainer greater than a predetermined distance,
- wherein the stopper is located in a region of the module cover where downward motion of the module cover is not limited by the horn switch.
An airbag module for a vehicle steering wheel comprising:
- a module cover having a plurality of spoke fitting portions;
- a first horn switch located under a portion of the cover not including one of the spoke fitting portions and a second horn switch located under one of the spoke fitting portions, wherein the first and second horn switches limit movement of the module cover away from a driver of the vehicle;
- and
- wherein the airbag module is configured so that movement of the airbag module away from a driver of the vehicle at a location where a horn switch is not present is limited by a stopper.
