Airbag device
First Claim
1. An airbag device for a vehicle, the airbag device comprising:
- an airbag operatively mounted to a predetermined component of the vehicle;
a gas generator for inflating the airbag with inflation gas; and
a detector operable to detect a load applied to the predetermined component of the vehicle prior to airbag deployment to allow inflation of the airbag to be controlled based on the applied load.

Abstract
An airbag device is provided to prevent an airbag from being deployed or to reduce the deployment force of an airbag when an airbag device or a vehicle-body component adjacent to the airbag device is leaned against by a vehicle occupant. In one form, a passenger-seat airbag device is set in an instrument panel and includes a bracket which is fixed to a vehicle-body member with, for example, a bolt. A strain gauge is attached to the bracket. When a lid covering the front side of a retainer is leaned against by a vehicle occupant, the weight of the occupant is transmitted to the bracket via the retainer, such that a small strain is generated in the bracket. Such a strain is detected by the strain gauge to allow the deployment force of the airbag to be reduced.
