Abstract
This disclosure generally relates to a headrest assembly, seat, and a method of use. In the disclosure, a head restraint is moveable from an upright position to a folded position by movement of either the push-button or a lever. The disclosed arrangement provides two ways to fold a head restraint, and can further be integrated with another assembly, such as a seat back folding assembly. The disclosed arrangement is further configured to resist vibration, leading to a tighter, more stable design, which provides increased customer satisfaction.
Claims15
A headrest assembly, comprising:
- a head restraint including a push-button and a push-lever, wherein the push-lever is rotatable by a pull cable, wherein the head restraint is moveable from an upright position to a folded position by movement of the push-button or the pull cable, wherein the head restraint includes a pawl configured to resist vibrations of the head restraint,
- wherein the head restraint includes a locking plate and a locking trigger engaged with the locking plate when the head restraint is in the upright position,
- wherein the locking trigger is configured to disengage the locking plate in response to movement of the push-button or pull cable,
- wherein the push-button is directly coupled to a push-pin,
- wherein the push-pin is directly coupled to the push-lever, and
- wherein the push-lever is coupled to the locking trigger via a linkage.
A seat for a motor vehicle, comprising:
- a seat back;
- a pull-cable;
- a headrest assembly, comprising:
- a head restraint including a push-button and a push-lever, wherein the push-lever is rotatable by a pull cable, wherein the head restraint is moveable from an upright position to a folded position by movement of the push-button or the pull cable, wherein the head restraint includes a pawl configured to resist vibrations of the head restraint;
- wherein the head restraint includes a locking plate and a locking trigger engaged with the locking plate when the head restraint is in the upright position, and
- wherein the locking trigger is configured to disengage the locking plate in response to movement of the push-button or the pull cable,
- wherein the pawl includes a first arm having a free end configured to directly contact a projection of the locking plate when the head restraint is in the upright position;
- and
- an actuator configured to pull the pull-cable to move the head restraint to a folded position and to fold the seat back.
A method, comprising:
- folding a head restraint from an upright position to a folded position by movement of a push-button or a cable, wherein the cable is connected to a push-lever, and
- resisting vibration of the head restraint using a pawl, wherein the pawl includes a first arm having a free end configured to directly contact a projection of a locking plate when the head restraint is in the upright position.
