Arm rest device for vehicles

摘要

An interior member on a side wall of a passenger room is formed with an arm rest body projecting inwardly of the passenger room and has a placed member on an upside part of the arm rest body for providing a place for an arm of the passenger to be put thereon, the placed member being detachably attached to the arm rest body and lockingly engaged therewith by an engagement mechanism having lock pawls integral with the placed member and engaged with an edge of an opening formed in the upside part of the arm rest device and ribs integral with the placed member and brought into abutment with the edge of the opening so that, as a primary collision has happened at a lateral side of vehicle, a secondary collision load of the passenger imposed on the arm rest body forces the placed member to be released from the locking engagement by the engagement mechanism.
