Adjustable head restraint assembly for vehicle seats

摘要

A head restraint assembly is provided with a head restraint frame mounted to a post for movement along the post for adjustment relative to a vehicle seat. The head restraint frame has a contact surface. A biasing member is mounted to the head restraint frame for movement relative to the head restraint frame to maintain the head restraint frame in a locked condition along the post. An actuation member is mounted to the head restraint frame for movement relative to the head restraint frame. The actuation member cooperates with the biasing member such that movement of the actuation member moves the biasing member, thereby disengaging the biasing member from the post to permit movement of the head restraint along the post such that the biasing member engages the contact surface in the second position to provide feedback to the user of an unlocked condition of the head restraint frame.

主权项

1. A head restraint assembly comprising:
a head restraint frame adapted to be mounted to at least one post for movement along the at least one post to permit adjustment of the head restraint frame relative to a vehicle seat, the head restraint frame having a contact surface; a biasing member mounted to the head restraint frame for movement relative to the head restraint frame, the biasing member cooperating with the head restraint frame to maintain the head restraint frame in a locked condition along the at least one post; and an actuation member mounted to the head restraint frame for movement relative to the head restraint frame, the actuation member cooperating with the biasing member such that movement of the actuation member from a first position corresponding to the locked condition of the head restraint frame to a second position corresponding to an unlocked condition of the head restraint frame, moves the biasing member, thereby disengaging the biasing member from the at least one post to permit movement of the head restraint frame along the at least one post such that the biasing member engages the contact surface in the second position to provide feedback to a user of the unlocked condition of the head restraint frame; and wherein the engagement of the biasing member upon the contact surface provides an audible pressure point, for audible detection by the user during manual actuation of the actuation member.
