摘要

A head restraint assembly for a vehicle seat includes a base portion, a head restraint, and a locking mechanism. The head restraint is mounted with respect to the base portion and is selectively rotatable with respect to the base portion about a first axis. The locking mechanism includes a first lock member, a second lock member, and a first spring. The first lock member is mounted with respect to the base portion and defines a first plurality of teeth. The second lock member is movably mounted with respect to the head restraint and the first lock member. The second lock member defines a second plurality of teeth. The first spring continuously biases the second lock member toward the first lock member such that the second plurality of teeth continuously contact the first plurality of teeth.
