Abstract
The present invention, includes: a damper unit provided between an airbag module that acts as a damper mass for a steering wheel and the steering wheel to dampen vibrations of the steering wheel, an engagement mechanism provided in the airbag module that maintains the airbag module on the steering wheel in a relatively displaceable manner, and protecting means provided on the airbag module for stopping external forces to the engagement mechanism in a non-engaged state with the steering wheel, that may cause deformation, and thereby protecting the engagement mechanism.
Claims15
A driver seat airbag device, comprising:
- an airbag module provided with an airbag cushion and inflator for expanding and deploying the airbag cushion, and serving as a damper mass for a steering wheel;
- one or more damper units provided in between the airbag module and the steering wheel for damping vibration of the steering wheel;
- an engagement mechanism provided in the airbag module in parallel with the one or more damper units, for engaging with the steering wheel, and retaining the airbag module on the steering wheel while enabling relative displacement;
- and
- protecting means provided in the airbag module, the protecting means accepting external force that causes deformation of the engagement mechanism to protect the engagement mechanism in a state in which the engagement mechanism is disengaged from the steering wheel.
