ABSTRACT:
A multi-stage door opening device. This device reliably retains the door as it was opened at a desired opening angle and generates no operational noise in opening and closing motions of the door and lengthens the using life. An arm is hinged to a car body and comprises a steel core totally coated with a high strength engineering plastic material. This arm is partially thinned in order to provide a plurality of locking portions. A hinge pin hole of the arm has a synthetic resin bushing placed beside the steel core. A stopper is engaged with a notched fixing portion of the arm for limiting a full door opening position. A locking unit is slidably penetrated by the arm and locked to one of the locking portions of the arm. A locking body of the locking unit receives a pair of roller units slidably contacting with the arm. Each roller unit comprises a roller carrier, a locking roller seated on the roller carrier and an elastic material placed on the back of the roller carrier for biasing the roller carrier and the roller toward the arm. The stopper comprises a shock absorber, having a plurality of shock absorbing projections, and a fixture having compression projections on its opposed sides.
