Abstract
A displaceable head restraint for a seat has a padded portion that is displaceable relative to a base part of the head restraint from a nominal position to a safety position using a driving mechanism and returnable to the nominal position using a restoring device. The restoring device includes a handle releasably connected to a receiver plate, and the receiver plate is positioned on a fixed portion of the base part. A cable having one end attached to the handle and an opposed end connected to a rotatable member is disposed between the padded portion and the base part. Application of a force on the handle that is opposed to a direction of displacement of the padded portion between the nominal position and the safety position rotates the rotatable member to return the padded portion to the nominal position.

A head restraint for use in a seat, the head restraint having a padded portion that is displaceable relative to a base part of the head restraint from a nominal position to a safety position using a driving mechanism and returnable to the nominal position using a restoring device, the head restraint comprising:
- a handle releasably connected to a receiver plate, wherein the receiver plate is positioned on a fixed portion of the base part;
- and
- a cable having one end attached to the handle and an opposed end connected to a rotatable member disposed between the padded portion and the base part, wherein application of a force on the handle that is opposed to a direction of displacement of the padded portion between the nominal position and the safety position, rotates the rotatable member to return the padded portion to the nominal position.
A head restraint for a vehicle having a padded portion that is displaceable relative to a base part of the head restraint between a nominal position and a safety position, the head restraint comprising:
- a driving mechanism having a first fixed member connected to the base part, a second displaceable member attached to the padded portion and displaceable with respect to the first fixed member between the nominal position and the safety position, and a third rotatable member rotatably mounted between the first fixed member and the second displaceable member, and rotation of the third rotatable member displaces the second displaceable member between the nominal position and the safety position;
- and
- a restoring device having a handle releasably connected to a receiver plate positioned on the first fixed member and a cable having one end attached to the handle and an opposed end connected to the third rotatable member, wherein application of a force on the handle, that is opposed to a direction of displacement of the second displaceable member between the nominal position and the safety position, returns the padded portion to the nominal position.
A head restraint for a vehicle having a padded portion that is displaceable relative to a base part of the head restraint between a nominal position and a safety position comprising:
- a driving mechanism having a first fixed member connected to the base part, a second displaceable member attached to the padded portion and displaceable with respect to the first fixed member between the nominal position and the safety position, and a third rotatable member rotatably mounted between the first fixed member and the second displaceable member, and rotation of the third rotatable member displaces the second displaceable member between the nominal position and the safety position;
- a restoring device having a swivel lever connected to a rear surface of the first fixed member, wherein the swivel lever includes a radially extending arm and a pin projecting perpendicular to the arm and the pin cooperatively engages the third rotatable member to restrict rotation of the third rotatable member;
- and
- a torque transmitting device for applying a restoring torque on the swivel lever along an axis of rotation of the third rotatable member to displace the second displaceable member between the nominal position and the safety position and return is the padded portion to the nominal position.
