Abstract

A headrest assembly that is rotatable to various positions includes a support defining a horizontal axis. A shell is rotatably mounted to the support. Notches are disposed on the support, and each notch is associated with one of the positions. A lever is mounted to the shell and has a locking portion rotatable about the pivot axis and partially disposed in one of the notches to prevent movement of the shell. An actuator is mounted to the shell and rotates the locking portion of the lever about a pivot axis in a direction transverse to the horizontal axis. The actuator moves the locking portion out of one of the notches to allow the shell to rotate about the horizontal axis. Furthermore, the actuator moves the locking portion into one of the notches to prevent the shell from rotating about the horizontal axis.

Description

CROSS REFERENCE TO RELATED APPLICATION

[0001] This application claims the benefit of provisional patent application Ser. No. 60 / 759,422 filed Jan. 17, 2006.BACKGROUND OF THE INVENTION

[0002] 1. Field of the Invention

[0003] The present invention generally relates to a headrest assembly rotatable to a plurality of positions.

[0004] 2. Description of the Related Art

[0005] As both the number and speed of vehicles on the road increase, the potential for serious occupant injury during a vehicle crash also increases. Vehicles now offer standard occupant restraint and protection devices to mitigate the effects of a vehicle crash on an occupant. Such devices include seatbelts, airbags, and headrest assemblies for vehicle seats. A headrest assembly situated on the top of a vehicle seat offers safety protection from crash-related injuries and provides comfort for an occupant. Vehicle headrest assemblies are categorized as integral, active, or adjustable. An adjustable headrest assembly typic...
