摘要 |
An arm support member for chairs or seats provided with an arm rest frame connected to said arm support member by a hinge mechanism. The arm rest frame is swung under the effect of a first spring into a vertical position, by a rotation about a horizontal axis parallel to and spaced apart from the longitudinal center plane (A-A) of the arm support member. The hinge mechanism also enables the arm rest frame to perform a sliding movement parallely to the hinge axis against the effect of a second spring only when the frame is in its raised position. Locking means is provided to hold the arm rest in both positions.
