Patent ID: 8590923

Claim:
A door hinge structure for passenger airbags, comprising: an airbag module installed inside a crash pad at a location spaced apart from the crash pad; and an airbag door having a hinge unit provided on an inner surface of the crash pad at a location facing the airbag module; wherein the airbag door is provided with a reinforcing bracket, the reinforcing bracket being embedded in the airbag door at an area around the hinge unit, on which a stress is concentrated when an airbag cushion deploys from the airbag module, thus increasing a strength of the airbag door; wherein the reinforcing bracket includes: base parts arranged in opposite sides of the hinge unit with respect to a longitudinal axis of the hinge unit and connected to the airbag door; side connection parts connecting the base parts to each other at opposite distal ends of the base parts and arranged along a bent part of the hinge unit; and at least one center connection part connecting the base parts to each other between the side connection parts and arranged along the bent part of the hinge unit; wherein the side connection parts are exposed outside of the hinge part in a direction towards the airbag module in a way such that the stress generated when the airbag cushion deploys directly acts on the side connection parts; and wherein the side connection parts protrude more towards the airbag module than the at least one center connection part from the hinge part such that, when the airbag cushion deploys, the stress can act on the side connection parts before the stress acts on the at least one center connection part.
